Description

The The invention relates to an assembly of a motor vehicle after Preamble of claim 1.

A Such assembly has a support member and an on the support member arranged housing part of a Adjustment on. When arranged on the support element Housing part lie while the housing part and the Carrier element with associated flat Sections together.

A Such assembly can, for example, in one on a subframe a vehicle door arranged window regulator be provided. The carrier element is here by the subframe and the housing part through a housing of a drive device the window regulator realized.

At one of the DE 20 2005 018 483 U1 known adjusting device in the form of a window regulator device engages a housing part with pin a body-mounted carrier and engages in a further, arranged on the other side of the carrier housing part. By way of a suitable connecting means, for example a screw, the two housing parts are connected to one another and held on the carrier.

The housing parts of the DE 20 2005 018 483 U1 grasp a cable drum of the window lifter device, which is set into a rotary motion by a drive motor during operation of the window lifter device and drives a cable stretched along guide rails for adjusting a window pane. Due to the rotational movement of the cable drum during operation, a torque around the axis of rotation of the cable drum also acts on the cable drum enclosing housing parts, which must be accommodated in a suitable manner to prevent the housing of the adjusting rotates with its housing parts in total operation of the window regulator , On one of the housing parts, therefore, at least two positive locking areas are additionally provided for the positive engagement of the housing part in the carrier. For this purpose, pins on the carrier pass through a bore and a slot on the housing part and thus secure the housing part against rotation on the carrier.

The solution of DE 20 2005 018 483 U1 can preferably be used in plastic carriers. In the case of steel beams, a blind rivet may alternatively be provided as an anti-twist device.

by virtue of the additional positive locking areas for a positive engagement by means of pins must for the production of such components additional Tolerances are provided which the manufacture of these components elaborate. Are the tolerances too big, rattles the drive device optionally in operation. Are the tolerances too small, the assembly is difficult.

at However, attach additional blind rivets arise additional costs for blind rivets and additional Effort through required further assembly steps.

task The present invention is an assembly of the aforementioned To provide a simple way to provide a Anti-rotation of a arranged on a support element Housing part allows, while the assembly process not difficult and at the same time inexpensive.

These The object is achieved by an object having the features of the claim 1 solved.

at an assembly of the type mentioned is provided that on the flat portion of the support element and / or the housing part at least one press-in element for pressing into the associated flat section the housing part and / or the carrier element is arranged.

The The present invention is based on the idea of one or more additional press-in elements either on the support element or on the housing part or both on the carrier element as well as on the housing part to provide, between the flat Installation of the carrier element and the housing part Act. On a flat portion of the support element and / or the housing part is for this purpose at least one press-in part provided, which is mounted on the support member housing part in an associated areal section of the housing part or the support element is pressed and thus actuating forces can absorb in the plane of the abutting flat Portions of the housing part and the carrier element Act.

For this purpose, the at least one press-in element can be designed and provided to be pressed into the associated planar section of the housing part and / or of the carrier element during assembly of the housing part on the carrier element. For example, the housing part can be connected via a screw connection with the carrier element. When producing the screw connection, the at least one press-in element is then inserted into the associated flat section of the housing part (if the press-in element is arranged on the carrier element) or of the carrier element (if the press-in element is attached to the housing part) orders) is pressed. The press-in elements thus automatically occur in the assembly of the housing part on the carrier element in operative connection with the associated areal section and are pressed into the planar section. Special precautions to the associated planar portion, for example in the form of recesses or the like are not required for this purpose. The only prerequisite is that the press-in part by its shape and / or its material properties can be incorporated in the production of the connection between the housing part and the support member in the associated planar section.

advantage the solution according to the invention is that no additional tolerances are to be provided. through the press-fit is a backlash-free rotation in less expensive Made way, which is the assembly of a housing part on Carrier element not appreciably difficult.

moreover are no additional components for making a Anti-rotation, for example in the form of blind rivets or the like required and therefore no additional installation steps to Production of such anti-rotation devices.

The At least one press-in element can, for example, in the manner of a Mandrel of the flat portion of the support element and / or the housing part towards the associated planar Section of the housing part and / or the carrier element protrude. The thorn-like press-in then works at Production of the connection between the housing part and the carrier element in the associated planar Section and provides the anti-rotation.

Around forces acting during operation of the adjusting advantageous To record, the press-in element can be formed be that with at least a surface section of a Actuating direction of the adjusting opposite is. This is based on the idea, the press-in to so shape it to take in particular such forces can, in the operation of the adjustment to a twisting of the housing part on the support element lead would. Grasps the housing part, for example, a Cable drum, so the rotation must in particular around the axis of rotation the cable drum can absorb acting torques. The press-in element can then be designed, for example, in such a way that it is with at least one of its in the associated planar section protruding surfaces just the direction of actuation, So the forces acting around the axis of rotation of the cable drum forces, is opposite.

For example the press-in element can be conical or pyramidal from the flat portion of the housing part or protrude the support element and thus to the outside tapering to a point. Be the housing part and the support element with their associated flat sections then attached to each other, the press-in element on the one component in the associated planar section of the other component pressed and produces the twist-proof connection.

The at least one press-in element is preferably in the region of an attachment point for fastening the housing part to the carrier element arranged. Such an attachment point can, for example, a Have pins which is arranged on the housing part and when arranged on the support member housing part passes through the support element. Are several press-in elements provided, so these can be around the pin of the attachment point around be arranged while radially and / or circumferentially to each other be offset. The arrangement and number of press-fit can be chosen so that in the operation of the adjustment acting actuating forces just recorded effectively become.

When Another idea of the invention may just as much Press-in elements on the housing part and / or the carrier element be provided as in establishing the connection between the Housing part and the support element just yet in the respectively associated planar sections of the other Can incorporate component. The number of possible Press-in elements depends, for example, on the material properties of the housing part and the carrier element, wherein the number of pressfit can increase, if for example, the housing part with press-fit elements arranged thereon made of a hard material (for example made of metal) is and the support element simultaneously from a soft Material (for example, plastic) is made. The number the possible press-fit can continue from the arrangement the press-in elements on the housing part and / or on the carrier element of the shaping of Einpresselemente and for the production of the Connection between the housing part and the carrier element be dependent on applied connection forces.

Preferably should hereby form, size and number of press-fit be sized so that the generated by the connecting screws Force for (far-reaching) pressing in the material of the assigned Part is just enough. This succeeds, the one Twisting of the parts (housing part, carrier element) to maximize counteracting support surfaces and thus minimizing the risk of loosening the connection.

If the housing of the adjustment from formed two housing parts, which are arranged on both sides of the support member, the pin of a housing part for making a connection with the other housing part engage in a receptacle of the other housing part. The one housing part, for example, record a cable drum in the wet room of a vehicle door, while the other housing part encloses in a conventional manner electrical components, such as an electric motor for driving the cable drum. About the pin can be made for example by means of a screw connection between the two housing parts to connect the two housing parts clamped to the support member.

In an advantageous embodiment may be on the housing part be provided three attachment points, wherein at least one the attachment points arranged at least one press-in element is. It is conceivable here, at only one attachment point or provide more pressfit. It is also conceivable one or more press-in elements at each of the three attachment points to arrange in this way a particularly reliable To provide rotation.

Of the The idea underlying the invention is based on the following the embodiments shown in the figures closer be explained. Show it:

1 a plan view of an adjusting device with a cable drum arranged on a housing part;

2 a detailed view of an attachment point;

3 a sectional view through an attachment point;

4 a view of an attachment point on a housing part;

1 to 4 show in different views as a cable drive housing 1 trained housing part of an adjustment 6 in the form of a cable window lifter. The cable drive housing 1 holds a rope drum 2 in the operation of the window lift along a cable guide 21 guided rope for adjusting a window in a conventional manner up or unwinds.

The cable drive housing 1 is part of a two-part housing of the adjustment 6 and is located on one side of a support member forming a subframe 3 (please refer 3 ) at. On the other side of the subframe 3 there is a second housing part (see 3 ) in the form of a motor housing 4 , which is usually arranged in a drying room of a vehicle door, while the cable drive housing 1 is located in a wet room to adjust the also located in the wet room window of a vehicle door.

The cable drive housing 1 is about three attachment points 10a . 10b . 10c (please refer 1 ) with the subframe 3 connected and accesses this on the cable drive housing 1 arranged cones 12 (please refer 3 ) in recordings 41 of the motor housing 4 one. The pin 12 each attachment point 10a . 10b . 10c takes hold of the subframe 3 and is in a hole 410 the assigned recording 41 plugged. One in a central hole 120 of the pin 12 screwed in screw 5 then put from the side of the motor housing 4 , So from the dry room side, the connection of the motor housing 4 with the cable drive housing 1 ago.

At on the subframe 3 arranged cable drive housing 1 lies the cable drive housing 1 with a flat portion in the form of an annular support portion 11 on a flat section in the form of a contact surface 30 of the subframe 3 at. Like, for example 2 can be seen, lies the cable drive housing 1 not with the entire support section 11 to the assembly carrier 3 but the contact surface 30 of the subframe 3 is slightly smaller than the rest section 11 ,

As a contact surface 30 is in this context the surface of the subframe 3 defined with the surface formed support section 11 of the cable drive housing 1 at an attachment point 10 . 10a . 10b . 10c got into contact.

When the housing is mounted, ie with the subframe 3 connected cable drive housing 1 and motor housing 4 are the cable drive housing 1 on the one hand and the motor housing 4 on the other hand by the screw connections of the attachment points 10a . 10b . 10c against the subframe 3 pressed. The connection of the cable drive housing 1 with the subframe 3 must be designed so that even during operation of the adjustment 6 the cable drive housing 1 against rotation on the subframe 3 is held. This requires in particular that forces can be absorbed, which are about the axis of rotation D of the cable drum 2 act and are conditional that during operation of the adjustment 6 Tensile forces on the rope drum 2 adjoining rope of the adjusting device 6 be exercised and to a torque load of the cable drive housing 1 about the axis of rotation D in the direction of co-rotation of the cable drive housing 1 to lead.

As an additional anti-rotation is therefore at least one of the attachment points 10a . 10b . 10c additionally at least one press-in element 13 intended. The anti-rotation can at each of the three attachment points 10a . 10b . 10c be provided. It is also possible, a rotation only at one or two of the attachment points 10a . 10b . 10c to arrange.

To indicate that anti-rotation of the type explained below at each of the three attachment points 10a . 10b . 10c can be provided, according to the figures 1 the attachment point generally with the reference numeral 10 Mistake.

The press-in elements at the attachment point 10 are as of the flat edition section 11 of the cable drive housing 1 or from the flat contact surface 30 of the subframe 3 projecting, outwardly tapered elements designed and are such that they are in the arrangement of the cable drive housing 1 on the subframe 3 can work into each associated surface section of the other component. On the one hand, this concerns the shape and material properties of the pressfit elements 13 , but also the number of attachments 10 provided Einpresselement 13 ,

Exemplary embodiments of different press-in elements 13 are in 5a . 5b and 5c shown. A press-in element 13 may for example be cone-shaped ( 5a ), pyramidal with cuboid base ( 5b ) or pyramid-shaped without saucer ( 5c ) be configured. The pressfit elements 13 can either on the cable drive housing 1 or on the subframe 3 or also be arranged on both components, wherein, as in 5d schematically illustrates a variety of press-fit 13 radially and circumferentially around the pin 12 the respective attachment point 10 can be distributed.

The press-fit elements are advantageous 13 made of a hard material, such as metal, and are in a flat portion of a softer material, such as plastic, pressed. The pressfit elements 13 then act between the support section 11 of the cable drive housing 1 and the contact surface 30 of the subframe 3 and make a connection between the cable drive housing 1 and the subframe 3 in particular also actuating forces about the axis of rotation D of the cable drum 2 can record.

An advantage of the pressfit elements 13 is that no additional measures to the respectively associated flat sections in which the press-fit 13 be pressed, are provided. Additional recesses or holes or the like are not required. As a result, no additional tolerances in the manufacture of the components, in particular the cable drive housing 1 and the subframe 3 be provided. The connection between the cable drive housing 1 and the subframe 3 is when pressing the pressfit 13 automatically produced without backlash.

The essentially pyramid-shaped press-fit elements 13 according to 5b and 5c are advantageously aligned so that at least one surface section 130 the press-fit elements 13 during operation of the adjustment 6 acting actuation forces is flat opposite, so that the press-fit 13 can absorb the actuating forces effectively.

6 shows in a perspective view Einpresselemente 13 working on a support section 11 of the cable drive housing 1 are arranged. Clearly visible in 6 is also on the cable drive housing 1 arranged cones 12 for the passage of the subframe 3 and to engage in the recording 41 of the motor housing 4 with central bore arranged thereon 120 and additional locking elements 14 for latching connection of the cable drive housing 1 with the subframe 3 for example, for the purpose of pre-assembly.

7 and 8th show the cable drive housing 1 according to 6 before making the connection of the cable drive housing 1 , the motor housing 4 and the subframe 3 ( 7 ) and in the case of a compound ( 8th ).

How out 7 can be seen, are the press-in elements 13 protruding on the support section 11 of the cable drive housing 1 educated. Will the cable drive housing 1 to the subframe 3 set, so the pin passes through 12 the subframe 3 and picks up the shot 41 of the motor housing 4 one. The pressfit elements 13 on the cable drive housing 1 are not here in the subframe 3 pressed.

Will now be a screw 5 (please refer 3 ) in the screwing E in the recording 41 and the central hole 120 of the pin 12 screwed in, so are the cable drive housing 1 , the aggregate carrier 3 and the motor housing 4 pressed together. This will also the pressfit 13 on the cable drive housing 1 in the example made of plastic subframe 3 pressed in and are made at compound, as in 8th represented in the subframe 3 embedded, wherein the support section 11 of the cable drive housing 1 and the contact surface 30 of the subframe 30 lie flat against each other. By embedding the pressfit elements 13 in the subframe 3 can also shear acting actuating forces parallel to the plane of extension of the subframe 3 be recorded.

9 to 11 show an arrangement of press-fit 31 in the area of the contact surface 30 on the subframe 3 , Again, the press-in elements are formed as projecting, for example conical or pyramidal elements (see 10 ).

To the pressfit elements 31 with the rest section 11 of the cable drive housing 1 In turn, be the cable drive housing 1 by making a screw against the subframe 3 pressed and thereby the pressfit 31 on the subframe 3 in the cable drive housing 1 , which may be made of plastic, incorporated, for example. The aggregate carrier 3 In this embodiment, for example, be made of metal, for example steel.

Of the The idea underlying the invention is not based on the preceding limited embodiments described. In particular, it is conceivable Einpresselemente of the kind described on both the subframe and the cable drive housing provided. Basically, this is the type and arrangement the press-in variable, wherein advantageously the arrangement and shaping the press-in elements of the male actuating forces and the maximum einarbeitbaren press-fit, ie the maximum Number of in each assigned surface sections einpressbaren press-fit, be made dependent.
