Definitions
- the invention relates to an adjustment device for compensating for wear on a clutch, so that the clutch can always be actuated by an actuating device via the same actuating path.
- the invention also relates to a clutch with such an adjustment device, in particular a dry friction clutch, with the aid of which a torque flow can be established or interrupted in a drive train of a motor vehicle.
- the invention also relates to a pusher of an adjustment device.
- an adjustment device for a clutch with an actuation direction comprising a pusher movable in an actuation direction for disengaging the clutch, wherein the pusher has a drive ramp and an adjustment ramp (hereinafter also referred to as adjustment ramp element) in a transverse direction to the actuation direction, a drive element movable in the actuation direction for actuating the adjustment device with a first counter ramp, wherein the first counter ramp has a counter contour to the drive ramp and rests with the counter contour on the drive ramp in the actuation direction, an adjustment element movable in the transverse direction with a second counter ramp, wherein the second counter ramp has a counter contour to the adjustment ramp and can be placed with the counter contour on the adjustment ramp in the actuation direction.
- adjustment ramp element hereinafter also referred to as adjustment ramp element
- the adjustment element and the drive element are connected to one another in the transverse direction and the drive element is movably mounted on the adjustment element in the actuation direction, wherein the drive ramp and the counter contour are designed to be self-locking to the drive ramp and the adjustment ramp and the counter contour are designed to slide against one another in the transverse direction when there is a contact force in the actuation direction, and wherein the adjustment element is fixed in the actuation direction.
- the pusher must be fixed to the housing in relation to the circumferential direction so that the adjustment device can function. This fixation can be done, for example, on fixing bolts that are attached to the housing. However, a certain amount of extra work (e.g. centering bolts and their attachment to the housing) is required to fix the pusher.
- a certain amount of work is also required on the pusher to be fixed. For example, areas for contact with the centering bolts must be formed. This increases the material required for the component and may require more manufacturing effort. Another disadvantage is that the ramp areas with the fixing function differ in shape from the other ramp areas, which may also be problematic for production.
- An adjustment device with the features of claim 1, a pusher according to the features of claim 8 and a coupling with the features of claim 9 contribute to solving this problem.
- Advantageous further developments are the subject of the dependent claims.
- the features listed individually in the claims can be combined with one another in a technologically meaningful way and can be supplemented by explanatory facts from the description and/or details from the figures, whereby further embodiments of the invention are shown.
- An adjustment device for a clutch with one actuation direction is proposed.
- the adjustment device comprises
- a pusher movable relative to the housing in the actuation direction for disengaging the clutch, the pusher having a drive ramp and an adjustment ramp element in a transverse direction to the actuation direction,
- a drive element that is movable relative to the housing in the actuation direction for actuating the adjustment device with a first counter ramp, wherein the first counter ramp has a counter contour to the drive ramp and rests with the counter contour on the drive ramp in the actuation direction,
- an adjusting element which is movable in the transverse direction relative to the housing and has a second counter ramp, wherein the second counter ramp has a counter contour to the adjusting ramp element and can be placed with the counter contour on the adjusting ramp element in the actuation direction, and
- the adjustment element and the drive element are connected to one another in (or opposite) the transverse direction and the drive element is movably mounted on (or opposite) the adjustment element in the actuation direction.
- the drive ramp and the counter contour to the drive ramp are designed to be self-locking and the adjustment ramp element and the counter contour are designed to slide off one another in the transverse direction when there is a contact force in the actuation direction.
- the adjustment element is arranged stationary on the housing at least with respect to the actuation direction.
- the pusher is arranged stationary on the housing with respect to the transverse direction by the (first) actuation element.
- the adjustment device proposed here corresponds in particular to the adjustment device according to the DE 10 2021 122 730.5 mentioned at the beginning, whereby the adjustment ramp described there corresponds to the adjustment ramp element mentioned here.
- a special fixation of the pusher relative to the housing is proposed here.
- a conventional clutch has at least two pressure plates (e.g. but also a pressure plate, a counter plate, and a clutch disc arranged so that they can be clamped between them), one of which (e.g. pressure plate and counter plate) is connected to an input shaft and one (e.g. the clutch disc) to an output shaft, and which are in frictional connection with one another via friction elements when the clutch is closed.
- the distance between the pressure plates when the clutch is closed is determined by the thickness of the friction elements. If the friction elements wear, the distance between the pressure plates when the clutch is closed decreases.
- an actuating element of the clutch which is for example a release lever or a diaphragm spring tongue, covers a further distance between the open and closed clutch as wear increases.
- an upstream actuating device such as a clutch pedal, also covers this further distance.
- an adjustment device is arranged between the clutch and the actuating device.
- the drive element When the drive element is actuated on the input side in the actuation direction, for example via a clutch pedal, the drive element, which rests on the drive ramp, moves the pusher in the actuation direction via the first counter ramp, which then disengages the clutch on the output side, for example on a release lever or a plate spring tongue. Because the first counter ramp rests on the drive ramp in a self-locking manner, the transmission of such a movement or an associated force between the first counter ramp and the drive ramp in the actuation direction is possible without the first counter ramp slipping off the drive ramp and subsequently moving in the transverse direction.
- the adjustment ramp moves away from the second counter ramp, which is fixed in the actuation direction and therefore immobile.
- the clutch closes again, for example by means of a spring element, and the pusher is pressed back until the friction elements of the clutch are in contact with one another again.
- the adjustment ramp or the adjustment ramp element and the second counter ramp also come into contact with one another again.
- a force results between the second counter ramp and the adjustment ramp or the adjustment ramp element in the actuation direction, as the clutch pushes the pusher back a further distance than before, but the second counter ramp is immobile in the actuation direction. This force causes the second counter ramp to slide along the adjustment ramp or the adjustment ramp element and in the transverse direction.
- the drive element As the adjustment element is connected to the drive element in the transverse direction, the drive element is adjusted in the transverse direction by the sliding, so that the first counter ramp also slides along the drive ramp.
- the distance between the pusher and the drive element changes to the same extent as the distance between the pusher and the adjustment element, namely until there is no longer any force between the pusher and the adjustment element.
- the axial length in the actuation direction of the pusher and the adjustment element and the axial length of the pusher and the drive element always have the same, fixed difference when the gradient corresponds to one another (e.g. when the drive ramp and the adjustment ramp or adjustment ramp element have the same gradient or when the gradient ratio of the ramp systems is the same).
- the drive element therefore always remains in the same position in the actuation direction when the clutch is closed and does not pass on an extended path resulting from wear to an actuation device.
- the adjustment device is self-contained and independent of an actuating device.
- the adjustment device can then, for example, be installed directly on the clutch and does not require any further adjustment when later mounted with an actuating device.
- the adjustment device can also be combined with a variety of different actuating devices.
- Another advantage is that the adjustment device is completely self-actuating and requires no maintenance. There is also no need for a wear indicator, which would be required to indicate that maintenance is required.
- the proposed adjustment device has a small number of components, so that a correspondingly small number of manufacturing tolerances interact. The respective tolerances can therefore be chosen to be large enough so that the adjustment device can be manufactured inexpensively. In summary, a simple and comfortable clutch with low assembly and maintenance costs has been created.
- Disengaging the clutch by the pusher means that the pusher adjusts a (first) actuating element of the clutch.
- a (first) actuating element of the clutch is, for example, a release lever or a diaphragm spring tongue and acts directly or indirectly on at least one pressure plate of the clutch so that the pressure plates are moved away from each other and the force-locking contact between the friction elements of the pressure plates is eliminated.
- the clutch is opened, for example, to change a gear in a downstream transmission or during purely electric driving of a downstream hybrid transmission.
- a respective ramp preferably has a longer slope than the associated counter ramp, so that the counter ramp can rest safely on the ramp over a corresponding path in the transverse direction.
- the respective counter ramp or one of the counter ramps can also have a longer slope than the associated ramp, so that the ramp can rest safely on the counter ramp over a corresponding path in the transverse direction.
- the drive element is provided in particular for actuating the adjustment device.
- the drive element is provided so that an actuating device acts on it.
- the drive element has an actuating bearing that is provided for receiving the actuating device.
- such an actuating device is a push rod that acts on the drive element and is mechanically coupled to a clutch pedal or an automated device for actuating the clutch.
- the pusher has at least one contour which forms a positive connection with the (first) actuating element in relation to the transverse direction.
- the handle is a sheet metal part and the at least one contour is created by forming the sheet metal part.
- the pusher is in contact with the (first) actuating element (e.g. with the tips of the actuating levers) particularly due to its function in the adjustment device.
- Such actuating levers are mounted on the housing with swivel joints, for example, and are thus able to support a lateral force on the tip, e.g. in the transverse direction or in a circumferential direction of the coupling. In this way, a moment can be found here to support the rotation of the pusher.
- the contact point of the pusher with the (first) actuating element or the contact points of the pusher with the tips of the actuating levers) be designed in such a way that rotation is also prevented here.
- the centering bolts mentioned above and their fixation to the housing can be omitted.
- the proposed contour can be implemented or the contact point shapes and II. easier to implement than the previously known contact point on the ramp areas.
- the actuating direction is an axial direction and the transverse direction is a circumferential direction of a cylindrical coordinate system, wherein the pusher, the drive element and the adjusting element are formed coaxially (in particular to the axial direction).
- a compact adjustment device is created that can be easily arranged on a coupling that is also usually coaxially constructed.
- the drive ramp and the adjustment ramp as well as the counter ramps then each have a gradient along a trajectory that follows the circumferential direction.
- the drive element and the adjustment element can be connected, for example, via a toothing or axially interlocking projections.
- the pusher has at least one contour which forms a positive connection with the (first) actuating element relative to the transverse direction, wherein the contour is arranged along a radial direction between the adjustment ramp element and the drive ramp.
- the pusher has two contours which form a positive connection with the (first) actuating element in both circumferential directions.
- the adjusting device has a plurality of (first) actuating elements which are arranged distributed along the circumferential direction, preferably exactly three.
- ramp elements distributed around the circumference are provided as a drive ramp and/or as an adjustment ramp element.
- the counter ramps are then also divided into several parts.
- all ramp elements of a ramp are designed the same. This advantageously achieves uniform support of the drive element or the adjustment element as well as the pusher over the circumference.
- the adjustment device has a housing, wherein the adjustment element is mounted on the housing so that it can move in the transverse direction and is fixed in the actuation direction.
- the adjustment device is then self-contained and can function independently. It can be used as a single component with a large number of couplings of different designs.
- the adjustment device can be fixed to a fixed component of a coupling and in particular be designed to be integrated with the coupling.
- the position of the adjustment element is fixed in the actuation direction in order to serve as a counter bearing for a force between the adjustment ramp and the second counter ramp in this direction.
- a pusher for the described adjustment device is also proposed, wherein the pusher is a sheet metal part and has at least one contour for forming a positive connection with the (first) actuating element in relation to a transverse direction, wherein the contour is produced by forming the sheet metal part.
- the pusher has a drive ramp and an adjustment ramp element in a transverse direction to the actuating direction.
- the pusher is designed as a disk element with a rotation axis. The pusher can be moved in the adjustment device along the actuation direction.
- the pusher is connected to the (first) actuation element of the adjustment device via the at least one contour in such a way that the pusher is fixed in relation to the transverse direction, i.e. cannot be rotated in the transverse direction.
- the pusher has a plurality of drive ramps and adjustment ramp elements along the transverse direction (here, circumferential direction), which are each arranged in particular at equal intervals.
- the drive ramps are arranged in a radial direction on an outer edge of the pusher.
- the adjustment ramp elements are arranged in the radial direction on an inner edge of the pusher.
- the pusher is disk-shaped, with the contours being arranged in this area. The contours are in particular designed as bulges or elevations, so that a stop is formed for the (first) actuating elements resting on the pusher in relation to the transverse direction.
- a clutch for selectively connecting or separating an input shaft and at least one output shaft is further proposed, wherein the clutch has the described adjustment device.
- the adjustment device and the clutch can be integrated as a single unit and share a common housing. This reduces the number of components, so that fewer component tolerances interact.
- the adjustment device can be provided as a separate component and arranged on a clutch mount.
- the clutch has a plurality of partial clutches for a plurality of output shafts, wherein at least one partial clutch has the described adjustment device.
- a clutch is provided for an agricultural machine or construction machine, with a first output shaft serving to drive the machine and being, for example, the input shaft of a drive gear, and a second shaft being a power take-off shaft for a secondary application such as driving a cable winch or a lifting device.
- only the first partial clutch for the first output shaft is designed or equipped with an adjustment device, since this is subject to greater wear due to more frequent use, particularly under load.
- the pusher, the adjustment element and/or the drive element can have recesses distributed around the circumference for the passage of elements of the second partial clutch in order to create a particularly compact clutch.
- first, “second”, ...) primarily serve (only) to distinguish between several similar objects, sizes or processes, and in particular do not necessarily specify a dependency and/or sequence of these objects, sizes or processes. If a dependency and/or sequence is required, this is explicitly stated here or it is obvious to the person skilled in the art when studying the specifically described design. If a component can occur multiple times (“at least one"), the description of one of these components can apply equally to all or part of the majority of these components, but this is not mandatory.
- the invention and the technical environment are explained in more detail below with reference to the attached figures. It should be noted that the invention is not intended to be limited by the exemplary embodiments given. In particular, it should be noted that the figures and in particular the size relationships shown are only schematic. They show:

- Fig. 1 shows a clutch 2 known from DE 10 2021 122 730.5 with an adjusting device 1 in a perspective view.
- Fig. 2 shows the clutch 2 according to Fig. 2 in a side view in section.
- Figs. 1 and 2 are described together below.
- DE 10 2021 122 730.5 With regard to the basic function of a clutch 2 and the adjusting device 1, reference is made to DE 10 2021 122 730.5.
- the clutch 2 is suitable for optionally connecting or separating an input shaft 15 and at least one output shaft 16, wherein the clutch 2 has the adjustment device 1.
- the adjustment device 1 and the clutch 2 are integrated as a unit and share a common housing 12.
- the clutch 2 has a first partial clutch 17 and a second partial clutch 18 (only indicated).
- Each partial clutch 17, 18 is assigned to an output shaft 16, wherein only the first partial clutch 17 has the adjustment device 1.
- the first actuating elements 13 are assigned to the first partial clutch 17.
- the second actuating elements 19 are assigned to the second partial clutch 18.
- the adjustment device 1 comprises a pusher 4 which is movable in an actuating direction 3 for disengaging the clutch 2 or the first partial clutch 17, wherein the pusher 4 has a drive ramp 6 and an adjustment ramp (hereinafter also referred to as adjustment ramp element 7) in a transverse direction 5 to the actuating direction 3.
- the adjustment device 1 also has a drive element 8 which is movable in the actuating direction 3 for actuating the adjustment device 1 with a first counter ramp 9, wherein the first counter ramp 9 has a counter contour to the drive ramp 6 and rests with the counter contour on the drive ramp 6 in the actuating direction 3.
- the adjustment device 1 also has an adjustment element 10 which is movable in the transverse direction 5 and has a second counter ramp 11, the second counter ramp 11 having a counter contour to the adjustment ramp or to the adjustment ramp element 7 and being able to be placed with the counter contour on the adjustment ramp in the actuation direction 3.
- the adjustment element 10 and the drive element 8 are connected to one another in the transverse direction 5 and the drive element 8 is movably mounted on the adjustment element 10 in the actuation direction 3, the drive ramp 6 and the counter contour to the drive ramp 6 being self-locking and the adjustment ramp and the counter contour being designed to slide off one another in the transverse direction 5 when there is a contact force in the actuation direction 3, and the adjustment element 10 is fixed in the actuation direction 3.
- the clutch 2 has a pressure plate 20, a counter plate 21 and a clutch disk 22 arranged so as to be clamped between them, of which the pressure plate 20, the counter plate 21 is connected to the input shaft 15 and the clutch disk 22 is connected to the output shaft 16, and which are in frictional connection with one another via friction elements when the clutch 2 is closed.
- the distance between the pressure plates is determined by the thickness of the friction elements when the clutch 2 is closed. If the friction elements wear, the distance between the pressure plates decreases when the clutch 2 is closed.
- a first actuating element 13 of the clutch 2, which is shown here as a release lever covers a further distance between the open and closed clutch 2 as wear increases.
- an upstream actuating device such as a clutch pedal, also covers this further distance.
- an adjusting device 1 is arranged between the clutch 2 and the actuating device.
- the drive element 8 When the drive element 8 is actuated on the input side in the actuation direction 3, for example via a clutch pedal, the drive element 8 moves the pusher 4 in the actuation direction 3 via the first counter ramp 9, which rests on the drive ramp 6, which then disengages the clutch 2 on the output side, here via the first actuation element 13. Because the first counter ramp 9 rests on the drive ramp 6 in a self-locking manner, the transmission of such a movement or an associated force between the first counter ramp 9 and the drive ramp 6 in the actuation direction 3 is possible without the first counter ramp 9 sliding off the drive ramp 6 and subsequently moving in the transverse direction 5.
- the adjustment ramp or the adjustment ramp element 7 moves away from the second counter ramp 11, which is fixed in the actuation direction 3 and is therefore immobile, during the actuation and the associated movement of the pusher 4. If the actuation is released, the clutch 2 closes again, for example by means of a spring element, and the pusher 4 is pushed back until the friction elements of the clutch 2 are in contact with one another again. In the process, the adjustment ramp or the adjustment ramp element 7 and the second counter ramp 11 come into contact with one another again.
- the distance between the pusher 4 and the drive element 8 changes to the same extent as the distance between the pusher 4 and the adjustment element 10, namely until there is no longer any force between the pusher 4 and the adjustment element 10.
- the axial length in the actuation direction 3 of the pusher 4 and the adjustment element 10 and the axial length of the pusher 4 and the drive element 8 always have the same, fixed difference when the gradient corresponds to one another (e.g. when the drive ramp 6 and the adjustment ramp or the adjustment ramp element 7 have the same gradient or when the gradients of the ramp systems are the same ratio).
- the drive element 8 therefore always remains in the same position in the actuation direction 3 when the clutch 2 is closed and does not pass on an extended path resulting from wear to an actuating device.
- Disengagement of the clutch 2 by the pusher 4 is understood to mean that the pusher 4 adjusts a first actuating element 13 of the clutch 2.
- the first actuating element 13 is a release lever and acts directly on the pressure plate 20 of the clutch 2, so that the pressure plate 20 is removed from the counter plate 21 and the clutch disc 22 and the force-fitting contact between the friction elements of the pressure plates is canceled.
- Fig. 3 shows another known clutch 2 with an adjusting device 1 in a perspective view.
- Fig. 4 shows a pusher 4 of the clutch 2 according to Fig. 3 in a perspective view. Figs. 3 and 4 are described together below. Reference is made to the explanations for Figs. 1 and 2.
- the pusher 4 is to be fixed to the housing 12 relative to the circumferential direction (the transverse direction 5) so that the function of the adjustment device 1 is possible.
- This fixation takes place here on fixing bolts 23, which are attached to the housing 12.
- a certain amount of additional effort e.g. fixing bolts 23 and their attachment to the housing 12 is required to fix the pusher 4.
- a certain amount of effort is also required on the pusher 4 to be fixed.
- areas 24 for contact with the fixing bolts 23 must be formed. This increases the material required for the component and may require more manufacturing effort.
- Another disadvantage is that the ramp areas with the fixing function differ in shape from the other ramp areas, which may also be problematic for production.

- the pusher 4 is designed as a disk element with a rotation axis. The pusher 4 can be moved in the adjustment device 1 along the actuation direction 3.
- the pusher 4 is connected via the contours 14 to the first actuation elements 13 of the adjustment device 1 in such a way that the pusher 4 is fixed with respect to the transverse direction 5, i.e. cannot be rotated in the transverse direction 5.
- the pusher 4 has a plurality of drive ramps 6 and adjustment ramp elements 7 along the transverse direction 5 (here the circumferential direction), each of which is arranged at equal intervals.
- the drive ramps 6 are arranged in a radial direction 25 on an outer edge of the pusher 4.

- Fig. 8 shows the coupling 2 according to Fig. 7 in a perspective view. Figs. 7 and 8 are described together below. Reference is made to the explanations of Figs. 1 to 6.

- the adjustment element 10 and the drive element 8 are connected to one another in (or opposite) the transverse direction 5 and the drive element 8 is movably mounted on (or opposite) the adjustment element 10 in the actuation direction 3.
