Description

The invention relates to a brake caliper arrangement for a vehicle disc brake. The vehicle can in particular be a motor vehicle and/or a road vehicle. For example, the vehicle can be a passenger car, a truck or a bus.

Brake caliper assemblies and in particular floating brake calipers are known and established in the art. Generally, they are used to position brake pads relative to a rotating brake disc to produce braking action. An example of an existing brake caliper assembly is shown in the KR 101208370 B1 to find.

The prior art example also shows the established principle of the floating caliper housing, which includes guide pins. These are rigidly coupled to the caliper housing and typically mechanically attached to it. The guide pins form elongated projections, for example in the form of cylindrical shafts, and are each accommodated in a guide recess in a brake pad carrier. The brake pad carrier is not movable relative to the brake disc and is attached to a steering knuckle, for example. The floating brake caliper housing, on the other hand, can be moved relative to the brake disc and the brake pad carrier.

In sum, this means that the guide pins, which guide a relative movement between the brake pad carrier and the brake caliper housing, have so far been on the movable component, i.e. H. the brake caliper housing.

While appropriately designed caliper assemblies are accompanied by various advantages, there remains room for improvement. For example, the NVH properties (noise, vibration, harshness) of existing brake calipers can be further improved, in particular to limit vibrations and associated braking noise. Additionally, it is desirable to limit the weight of existing caliper assemblies.

Accordingly, it is an object of this invention to provide a brake caliper assembly with improved NVH characteristics, particularly limited weight.

This object is achieved by the subject matter according to the appended independent claim 1. Advantageous embodiments are disclosed in this description, in the figures and in the dependent claims.

Accordingly, a brake caliper assembly for a vehicle disc brake is disclosed, the brake caliper assembly comprising: a brake caliper housing having a receiving portion for a brake piston; a brake pad carrier configured to slidably receive a pair of brake pads; and at least one guide pin configured to guide relative (e.g., sliding) movement between the caliper housing and the brake pad carrier; wherein the guide pin is attached to the brake pad carrier or is formed in one piece with it and is slidably received in the brake caliper.

The caliper assembly may be a floating caliper. The brake caliper housing can therefore be slidably connected to the brake pad carrier or, viewed differently, can be movable relative to the brake pad carrier and/or supported by it. This can be provided by a brake caliper housing that is coupled to the brake pad carrier via at least one guide pin. This means that the brake caliper housing can be carried by the guide pin, in particular in such a way that it is axially displaceable along the guide pin.

The brake pad carrier, on the other hand, may be stationary (i.e. may not be movable relative to the brake disc). It can be attached to a vehicle component that is not movable relative to the brake disc, for example a steering knuckle.

There can be one or more guide pins, in particular two guide pins. One of the guide pins may be positioned on a rear side and the other may be positioned on a front side of the brake caliper assembly (e.g., "front" and "rear" with respect to a forward rotation direction of the brake disc). If reference is made here to only one guide pin, this does not exclude the possibility that at least one corresponding second guide may exist. On the other hand, when reference is made to two guide pins, this does not exclude that only one guide pin may be provided.

The guide pin can also be referred to as a rod. It can be set up according to known examples. For example, it can be an elongated element or include it, in particular have a cylindrical shaft section. At least a part (e.g. an axial section) of this shaft section can be accommodated in a guide recess in the brake caliper housing.

The caliper housing can be a fist brake caliper. It may have a finger side on (or opposite to) a first side surface of a brake disc of the vehicle disc brake. It can have a piston side that includes the receiving part and is arranged opposite another side surface of the brake disc. The piston side and the finger side can be connected by a bridge part. The bridge part can extend along and in particular essentially parallel to an axis of rotation of the brake disc. In other words, the brake caliper housing can therefore bridge, span and/or partially enclose the brake disc.

As used herein, references to terms such as axial, radial and circumferential may generally refer to the axis of rotation of the brake disc. An axial direction may extend along the axis of rotation, a radial direction may extend at an angle to the axis of rotation, and a circumferential direction may extend about the axis of rotation.

The receiving part for the brake piston can define a recess or a cavity in which the brake piston can be received. It may have a round cross-section and/or may be generally cylindrical. It may have an open end surface or an open base, with the end surface or base facing a brake pad carried by the brake pad carrier. The receiving part can be configured to define a hydraulic chamber together with the brake piston, wherein the hydraulic pressure in the hydraulic chamber can be adjusted to move the brake piston to activate or deactivate the brake.

The brake pad carrier may include a finger side positioned on the same side surface of the brake disc as the finger side of the caliper housing. The brake pad carrier may include a piston side positioned on the same side surface of the brake disc as the piston side of the brake caliper housing. The brake pad carrier can include at least one bridge part that connects its finger side and piston side. In particular, two bridge parts can be provided which form circumferential outer edge sections of the brake pad carrier.

The brake pad carrier and the brake caliper housing may be configured according to known examples (in addition to the characteristic arrangement of the guide pins according to this disclosure). Accordingly, the brake pad carrier can form a frame structure in which the brake pads are received on both sides of the brake disc, while also slidably supporting the brake caliper housing. The brake caliper housing can be set up to contact and move the brake pads relative to the brake disc in accordance with a brake piston movement.

It has been found that providing the at least one guide pin on the brake pad carrier helps reduce noise and vibration generated by the brake caliper assembly during braking. It also provides the potential to reduce the weight of the caliper assembly without compromising braking performance.

For example, it has been found that appropriately positioning the at least one guide pin means that the size and mass of the movable caliper housing is reduced. Because the caliper housing is movably guided, it tends to move (particularly tilt) and vibrate more during braking compared to the non-movable brake pad carrier. Accordingly, the present solution allows the size and mass of the tiltable and vibration-prone component of the caliper assembly to be reduced. In addition, the rigidity of the non-movable brake pad carrier can be increased, e.g. B. due to the omission of previously provided guide recesses for receiving prior art guide pins attached to the caliper housing. The foregoing helps to reduce the overall level of noise and vibration generated by the caliper assembly.

The overall level of elastic deformation of the brake caliper assembly can also be reduced because the guide pins no longer form an extended lever arm by means of which the tiltable brake caliper housing is received in the brake pad carrier. The mass of the tiltable caliper housing can also be reduced because it no longer includes the guide pins. Accordingly, the levels of torque transmitted to the brake pad carrier through the movable and possibly tilting caliper housing may be reduced. The rigidity of the brake pad carrier can also be increased, e.g. B. by omitting guide recesses in the brake pad carrier and instead attaching the guide pins to it. As a result, the overall level of elastic deformation of the components of the caliper assembly can be reduced. This can enable a corresponding reduction in the mass of, for example, the brake pad carrier.

Particularly in connection with tilting movements of existing caliper housings during braking, it has been found that uneven pressure distributions can occur along existing guide pins attached to such caliper housings. For example, the guide pins can be bent and/or inclined within the guide recesses of the brake pad carrier in which they are accommodated. This can result in varying contact pressures along the length of the guide pins. Specifically, so-called fluttering can occur, which can cause the guide pins to vibrate within the guide recesses in which they are accommodated.

However, using the present solution, the extent or level of such flutter can be reduced. This is due to the reduced overall level of elastic deformation discussed above. Furthermore, the contact area between the guide pins and a recess in which they are received can now be reduced compared to existing solutions, thereby also reducing the size of the fluttering surfaces in contact with each other (and accordingly limiting the level of vibrations generated). For example, it has been found that the present solution (e.g. due to the reduced level of bending moments transmitted between the components, see above) requires smaller contact areas between the at least one guide pin and a guide recess (or other receiving component) in which he is included, makes possible. This also means that the size of potentially fluttering surfaces in contact with each other can be reduced, thereby limiting a level of vibration transmitted between the caliper housing and the brake pad carrier.

Again, limiting the size of the contact areas and the level of transmitted vibration allows for a reduction in the mass of the caliper assembly.

According to one embodiment, the brake caliper housing comprises a guide recess in which the guide pin is received. The guide recess can z. B. be a hole, a cavity, a blind hole or a through hole. It can have a cylindrical shape. In one example, the guide recess is an elongated hole.

In general, a shape and in particular a cross section of the guide recess can correspond to a shape or a cross section of the guide pin.

The guide pin and/or the guide recess can extend axially. Their long axes can coincide. There can be exactly two guide recesses (and two guide pins). One may be positioned on a leading edge and one on a trailing edge of the caliper assembly.

In one embodiment, the guide pin rests on at least one elastic element that is accommodated in the guide recess. The elastic element can also be referred to as an elastic seat. The brake caliper housing and/or the brake pad carrier can both be metallic elements, in particular made of cast iron. The guide pin can also be a metallic element. The elastic element can be more elastic than the brake housing and/or the brake pad carrier and/or the guide pin. For example, it can be at least twice as elastic, at least four times as elastic or at least ten times as elastic as the brake caliper housing and/or the brake pad carrier and/or the guide pin. The elasticity can be measured, for example, in terms of a modulus of elasticity of the corresponding elements and materials.

In general, the elastic property of the elastic element may indicate a significant macroscopic elastic deformability (e.g. greater than 0.1 mm) under operating conditions.

The guide pin can only be in contact with or rest against the elastic element (apart from the brake pad carrier to which it is attached). In other words, it is possible that there is no contact with and/or no contact with an element, in particular a comparatively inelastic element or a significantly less elastic element (e.g. an element that is less than half as elastic, less than a quarter as elastic or less than a tenth as elastic).

The elastic element may include or consist of a non-metallic material. In one example, the elastic element includes (or consists of) a plastic material and/or a rubber material. The rubber material may be a natural rubber material or a synthetic rubber material.

Additionally or alternatively, the elastic element may be an elastic sleeve, an elastic bushing or an elastic disk adapted to contact the guide pin. Viewed another way, the guide pin may be accommodated in and in direct contact with the elastic member. Accordingly, a surface of the elastic member that contacts the guide pin can act as a sliding surface as the caliper body slides along the guide pins. In general, the elastic element can surround and/or contact at least a portion of the guide pin. The section can be a section of the guide pin which is separated from the brake pad carrier and e.g. B. protrudes in the direction of the brake caliper housing. In one example, the section may be formed by a free end of the guide pin.

Additionally or alternatively, the elastic element can be set up to be accommodated in the guide recess in a non-movable manner. Viewed differently, the elastic element may not be movable relative to the guide recess and the brake caliper housing during operation of the brake caliper assembly. For this purpose, it can, for example, be glued to the guide recess or another part of the brake caliper housing. Additionally or alternatively, it can be held in the guide recess by a positive fit (e.g. a tight fit) and the corresponding frictional forces resulting therefrom.

Alternatively, the elastic element can be held on the guide pin, e.g. B. through a positive fit (e.g. a tight fit). In this case, it can be movable relative to the caliper housing and its guide recesses. For example, the elastic element can be a bushing or sleeve into which a shaft portion of the guide is inserted (and is not movable relative thereto). Alternatively, the elastic member may define an elastic portion disposed on the guide pin (e.g., received in a recess thereof). There can be a variety of such elastic sections, e.g. B. distributed in a circumferential direction of the guide pin and / or forming an elastic arrangement.

Providing an elastic member according to any of the examples discussed herein may further help reduce vibrations transmitted from the moving caliper housing to the brake pad carrier. In addition, it can dampen tilting movements of the brake caliper housing relative to the brake pad carrier and the guide pin attached thereto.

In one example, the guide pin is mechanically attached to the brake pad carrier. Alternatively, he can e.g. B. welded or glued to the brake pad carrier or formed in one piece with it. The latter can be achieved by forming the guide pins and the brake pad carrier as a jointly produced, cast part. The mechanical fastening can e.g. B. include clamping the guide pin on and/or within the brake pad carrier. Additionally or alternatively, the guide pin can be mechanically fastened to the brake pad carrier by means of a screw connection.

For example, the brake pad carrier can have at least one threaded section, e.g. B. include a threaded through hole. The guide pin may be provided with a threaded portion adapted to engage the threaded portion. The guide pin may be screwed into the threaded portion, thereby mechanically attaching it to the brake pad carrier. A portion of the guide pin, and particularly a free end, remote from (and/or protruding from) the threaded portion may protrude relative to the through hole and toward the caliper housing.

The present solution and in particular the screw connection make it possible to design the portion of the brake pad carrier (e.g. comprising the above through hole) to which the guide pin is attached with limited dimensions. This is particularly true in comparison with dimensions of sections of existing brake pad carriers in which the guide pins have previously been movably accommodated and which, for. B. have comparatively large guide recesses.

On the other hand, due to the limited transmitted torques (e.g. due to the reduced mass of the brake caliper housing, which no longer includes the guide pins), the guide recesses in the brake caliper housing can also be provided with a limited size. Consequently, when arranging and attaching the at least one guide pin as described herein, the overall size and therefore mass of the caliper assembly may be reduced.

In general, the guide pin may be provided as a one-piece element. It may be the only element required to provide attachment to the brake pad carrier and be housed in the brake pad housing. Consequently, unlike some prior art examples, it is possible not to provide a multi-part assembly in which a guide pin member is secured to the brake pad housing (in the prior art) by a separately provided lock nut member. Further embodiments of this disclosure may include a multi-part arrangement, in particular comprising a corresponding lock nut.

Accordingly, the guide pin can comprise a threaded section in order to form a screw connection directly with the brake pad carrier, e.g. B. by inserting it into a threaded recess or hole of the brake pad carrier is screwed in. Alternatively, the threaded portion can engage a mechanical fastener (e.g. a lock nut discussed here) that secures the guide pin to the brake pad carrier.

According to a further example, the brake caliper assembly further comprises a dust sleeve connected to the brake caliper housing and the brake pad carrier. In particular, the dust protection sleeve can be attached (e.g. clamped, screwed or glued) to both the brake caliper housing and the brake pad carrier. The dust sleeve may surround or, viewed differently, enclose a portion of the guide pin that extends between the brake caliper housing and the brake pad carrier. The dust protection sleeve can be made of an elastic material, e.g. B. material according to one of the examples discussed in connection with the elastic element accommodated in the guide recess. The dust sleeve can prevent dirt from entering the guide recess and/or between surfaces of the guide pin and caliper housing that contact and slide along each other.

In one example, the brake pad carrier and the guide pin comprise or are formed from a different material, in particular a material of the guide pin being more elastic than a material of the brake pad carrier (e.g. having an elastic modulus that is at least 3%-5% higher ). For example, the brake pad carrier can comprise or be formed from steel, while the guide pin can comprise or be formed from a different and more elastic steel alloy (e.g. with an elastic modulus that is at least 3%-5% higher). Alternatively, the brake pad carrier may comprise or be formed from aluminum, while the guide pin may comprise or be formed from a different and more elastic aluminum alloy (e.g. with a modulus of elasticity that is at least 3%-5% higher).

1 shows a brake caliper assembly 10 which is in principle arranged in accordance with prior art solutions, particularly with respect to the illustrated arrangement and attachment of guide pins 28, as discussed below. Connecting protruding parts 29 for explaining an embodiment of this invention are also indicated schematically and are discussed in more detail below.

The brake caliper assembly 10 from 1 is set up according to well-known principles of a floating saddle. It includes a brake caliper housing 12, which is slidably supported by a stationary brake pad carrier 14.

The brake caliper assembly 10 is generally set up, brake pads 26 (one of which is in 1 is partially visible), which are received and guided in the brake pad carrier 14 against a brake disc 16. Only part of the outer peripheral edge of the brake disc 16 is in 1 indicated by a dashed line, the brake disc 16 being generally set up according to known examples. Furthermore, in 1 an axis of rotation R, about which a brake disc 16 rotates, indicated schematically by a dashed line.

The brake caliper housing 12 includes a receiving part 15, of which in 1 only an outer wall is visible and which is designed as a (not visible) open cylindrical cavity. A brake piston, not shown, can be accommodated in the receiving part 15.

The brake caliper housing 12 includes a piston side 18, which is located on a first side surface of the brake disc 16 and specifically on the same side surface as the receiving part 15. Furthermore, the brake caliper housing 12 includes a finger side 20, which is located on the corresponding opposite side surface of the brake disc 16 compared to the piston side 18. The finger side 20 includes (by way of example only) two finger parts 21 according to known configurations.

The finger side 20 and the piston side 18 are connected to one another by a bridge part 22. The bridge part 22 overlaps the outer peripheral surface of the brake disk 16 or, viewed differently, spans the brake disk 16 axially and/or extends from one of the side surfaces of the brake disk 16 to the other.

In a well-known manner, in 2 the brake piston accommodated in the receiving part 15 and the inside of the finger parts 21, which face away from the viewer, are set up to form the brake pads 26 and press them against the brake disc 16.

Like the brake caliper housing 12, the brake pad carrier 14 includes a piston side 18, a finger side 20 and a bridge part 22. It should be noted that the weight savings made possible by the present solution can be achieved in particular by reducing a volume of the finger side 20 of the brake pad carrier 14. There, the so-called outer carrier, to which the arrow of the lower reference number 20 points, can be reduced in size or even omitted due to the increased rigidity of the disclosed brake pad carrier 14.

Guide grooves 24 are provided on an inside of the bridge part 22 to slidably receive two brake pads 26, which in 1 is partially visible. The brake pads 26 are located on opposite side surfaces of the brake disc 16. The brake pads 26 are generally identical to one another, but are differently oriented to face different side surfaces of the brake disc 16.

1 also illustrates that the movable caliper housing 12 is slidably supported by and guided relative to the brake pad carrier 14 by means of guide pins 28 on both a rear side and a front side of the caliper assembly 10.

The arrangement and design of the guide pins 28 corresponds to examples of the prior art, and the characteristic design according to this invention will be explained with particular reference to 2 discussed. According to the state of the art configuration of 1 the guide pins 28 are each accommodated in a cylindrical blind hole (not shown) in the brake pad carrier 14. An axial length of the blind holes exceeds that of the guide pins 28, so that the latter can slide axially backwards and forwards within the blind holes.

The guide pins 28 are attached to the brake caliper housing 12 by means of a screw connection. Specifically, mounting projections 31 are provided on each of a rear side and a front side of the brake caliper housing 12, wherein the mounting projections 31 each include an invisible through hole. The guide pin 28 is aligned with the through hole to engage a lock nut 33 provided on an opposite side of the fastening projections 31. In this way, the guide pin 28 is mechanically attached to the fastening projections 31 and consequently to the caliper housing 12.

1 also schematically illustrates connecting protrusions 29 which may be used to provide the alternative location and attachment of the guide pins 28. It should be noted that in order to use the connecting protruding parts 29, the fastening projections 31 would also have to be repositioned so that the through holes 34 in the connecting protruding parts 29 and those in the fastening protrusions 31 are aligned. This is not specifically illustrated.

2 is a sectional view of a portion of a brake caliper assembly 10 according to an embodiment of this invention. The brake caliper assembly 10 can be according to the example of 1 be formed, except for the differences in relation to the guide pins 28, which are discussed below. In 2 Only one of the guide pins 28 and a connection formed thereby are shown. Nevertheless, both guide pins 28 (which are generally similar 1 may be positioned on both a rear side and a front side of the brake assembly 10) may be set up according to this example.

2 shows a guide pin 28 which is configured as a one-piece metallic element. Specifically, the guide pin 28 is set up as a bolt-like element. The guide pin 28 has an optional head part 30 and an elongated shaft part 32. The shaft part 32 extends parallel to the axis of rotation R of the brake disc 16.

The guide pin 28 is inserted into a through hole 34 provided in the brake pad carrier 14. The connecting hole 34 is provided in a connecting projecting part 29 as shown in 1 can be positioned as specified. However, the connecting protruding part 29 could also be positioned differently. Furthermore, the through hole 34 could be provided in another part of the brake pad carrier 14, and the brake pad carrier 14 could be free of any connecting protruding parts 29.

The guide pin 28 is inserted into the through hole 34 in such a manner that its head portion 30 acts as a stop member by abutting a surface of the brake pad carrier 14. The shaft part 32 extends in the direction of the brake caliper housing 12 and extends into a guide recess 38 provided therein. At least a part of the shaft section 32, which is adjacent to the head part 30, is provided with a thread. The through hole 34 is also threaded. Accordingly, a screw connection is formed between the guide pin 28 and the through hole 34, through which the guide pin 28 is mechanically fastened to the brake pad carrier 14. As a result, the guide pin 28 is not movable relative to the brake pad carrier 14.

The guide recess 38 of the brake caliper housing 12 is set up as a through hole that is aligned with the through hole 34 provided in the brake pad carrier 14. A cross-sectional shape of the guide recess 38 corresponds to a cross-sectional shape of the guide pin 28 and more specifically its shaft part 32. Accordingly, the guide recess 38 receives and surrounds at least an axial section of the guide pin 28.

As a further optional feature, an elastic element 40 in the form of a plastic or rubber bushing is inserted into the guide recess 38. The elastic element 14 surrounds and contacts the guide pin 28. Accordingly, the guide pin 28 lies directly against the elastic element 40 and slides along its inner surface.

Such relative movement occurs when the caliper housing 12 is offset according to known floating caliper principles. In this case, the caliper housing 12 slides together with the elastic element 40 (which is pressed into the guide recess 38, being immovable relative to the caliper housing 12) along the shaft part 32 of the guide pin 28 and consequently relative to the brake pad carrier 14.

2 also shows a flexible and in particular elastically deformable dust protection sleeve 42, the axial end sections of which are attached to each of the brake caliper housing 12 and brake pad carrier 14. The flexible and in particular elastic deformation can occur during the sliding movement of the brake caliper housing 12 relative to the brake pad carrier 14.

3 shows a cross section of the elastic element 40 of 2 . It can be seen that the elastic member 40 is provided with a round, ring-like cross-section, that is, generally configured as a tubular member. Consequently, it can accommodate and reliably contact the correspondingly shaped round cross section of the shaft part 32 of the guide pin 28.

The 4 and 5 are cross sections showing further embodiments of this disclosure. As a mere example, the guide pin 28 is in the 4 and 5 formed in one piece with the brake pad carrier 14. Alternatively, the guide pin 28 could be mechanically attached to the brake pad carrier 14, similarly 2 .

A difference to 2 concerns the elastic element 40. In the 4 and 5 the elastic element 40 is arranged on the guide pin 28 and can be moved together with it relative to the brake caliper housing 12 and its guide recess 38.

In 4 A plurality of elastic elements 40 are provided, each elastic element 40 forming an elongated elastic section 41. The elastic portions 41 are distributed in a circumferential direction and each received in a correspondingly shaped recess 43 provided in an outer peripheral surface of the guide pin 28.

In 5 only one elastic element 40 is provided. It forms a continuous bushing in which the guide pin 28 is inserted. The elastic element is held on the guide pin 28 as it is elastically deformed during insertion.
