Description
Technical Field
The invention relates to a clutch device and a drive train for a motor vehicle.
Background
Plate spring clutches have been pioneered, particularly for applications in motorcycles. However, the implementation of the process for the manufacture of the component parts is relatively complex. The sheet carrier is usually manufactured by means of a roll forming process, which results in the use of complex dies and relatively high energy requirements.
Clutch devices are known from two documents WO 2016/131450 a1 and WO 2016/082832 a1, in which the plate carriers are connected to the hub element in a substantially rotationally fixed manner via leaf springs. The leaf spring serves here for the axial force application of the plate package for the purpose of transmitting torque in frictional engagement within the clutch device.
It is also known from WO 2014/139526 a1 to provide a spring mechanism between the input side and the output side of the clutch device in order to increase the pressing force or to reduce the pressing force required for closing the clutch device. The contact pressure can be generated and/or increased or decreased depending on the operation by means of the leaf springs taught in this document as spring means.
WO 2013/000455 a1 discloses a wet clutch, which is preferably embodied as a multi-disk wet clutch for motorcycles. The clutch includes an inner cover and an outer cover coaxially disposed on a transmission main shaft. First friction disks are engaged with the outer cover and second friction disks are engaged with the inner cover, wherein the first and second friction disks are coaxially disposed in an alternating sequence. In order to support the housing in the event of centrifugal force loading, the housing can comprise an additional circumferential ring section.
Disclosure of Invention
In view of this, the object of the invention is to provide a small-volume clutch device which can be produced with little material and assembly effort and ensures a long service life.
This object is achieved by a clutch device according to the invention according to claim 1. Advantageous embodiments of the clutch device according to the invention are given in the dependent claims 2 to 9. In addition, a drive train for a motor vehicle is provided according to claim 10 with a clutch device according to the invention.
The features of the claims can be combined in any technically expedient manner, wherein for this purpose reference can also be made to the statements made in the following description and to the features in the drawings, which comprise additional embodiments of the invention.
The invention relates to a clutch device for transmitting torque between a drive and a driven device, comprising: an inner and an outer plate carrier which are rotatably supported about an axis of rotation; at least one first friction disk, which is arranged on the inner disk carrier in a torque-engaging and axially displaceable manner, and at least one second friction disk, which is arranged on the outer disk carrier in a torque-engaging and axially displaceable manner. The first and second friction plates together form a plate pack. Further, the clutch device includes: force application means for effecting axial compression on the friction plates for transmitting torque between the inner plate carrier and the outer plate carrier via the friction plates; and a hub element for mechanically connecting the driven device, wherein the hub element is substantially rotationally fixedly connected to the inner plate carrier by means of a leaf spring, and the respective leaf spring is mechanically fixed to the hub element by means of a respective first end and to the inner plate carrier by means of a respective further second end thereof. One of the connections of the respective leaf spring to the respectively connected component is realized by means of a stepped bolt, wherein the stepped bolt is guided in an axially translatorily displaceable manner in the respectively further component connected by means of the leaf spring, and the stepped bolt has a bolt head on its end opposite the fastening on the component, said bolt head having a larger radial extent than the passage opening in the component guiding the stepped bolt in a translatory manner.
The outer sheet carrier is also referred to as a cover. The first and second friction plates are typically plates made of friction material and thin plate-like steel plates, which together form a high friction coefficient and can be produced at low cost.
This embodiment has the advantage that the inner leaf carrier, the leaf spring and the hub element together form a compact unit, which is also referred to as a leaf spring core, which ensures a precise positioning of the hub element with respect to the inner leaf carrier and thus a simple assembly, despite the continuous action of the leaf spring between the hub element and the inner leaf carrier.
The clutch device according to the invention is preferably a normally closed clutch, wherein a force is thus applied in order to disconnect the clutch from a normal state.
The connection of the leaf spring to the hub element is preferably effected by means of a stepped screw, wherein the stepped screw extends through the inner plate carrier in a translationally movable manner.
However, the opposite design is not to be excluded, in which the leaf spring is fixed to the inner plate carrier by means of a stepped screw and the stepped screw extends through the hub element in a translatorily displaceable manner.
The clutch device should furthermore comprise a counter plate which is connected in a rotationally fixed manner to the outer plate carrier, wherein the counter plate has a bore and the corresponding bore is shaped at least in regions complementary to the cross section of the bolt head of the stepped bolt.
This ensures that, during assembly, when the bolt heads of the stepped bolts are inserted into the corresponding bores in the counter plate, a precise angular positioning of the stepped bolts and thus a centering of the inner plate carrier and the hub element connected thereto with respect to the counter plate and thus with respect to the outer plate carrier is achieved.
Preferably, it is provided that the stepped screw is mechanically connected to the respective component by means of a riveted connection. The stepped screw itself here constitutes a rivet.
The stepped screw and the inner plate carrier can be designed such that they can form-fittingly pretension the leaf spring between the inner plate carrier and the hub element.
This means that, in particular, the radially more projecting head of the stepped bolt achieves that the inner plate carrier is at a defined maximum distance from the hub element. In this position the leaf spring is pretensioned. This makes the assembly of the clutch device easier, so that less effort is required for the axial pretensioning for the installation of the unit consisting of the inner disk carrier, the hub element and the leaf spring, also referred to as leaf spring core, and if necessary for the replacement of the disks.
The clutch device can furthermore have a central nut for mechanically connecting the hub element to the transmission input shaft, and a release bearing for compensating for a rotation between a rotating structural element of the clutch device and the connected transmission input shaft.
the central nut closing clutch device is characterized in that: the central nut, when fitted, moves the counter-pressure plate into a mounting position in which the leaf spring causes a defined pressing force on the plate package, so that the clutch device can transmit a defined torque.
The counter-pressure plate can have a centering device, which centers the release bearing.
The inner plate carrier can have at least one and preferably a plurality of release tongues, to which an axially acting force can be applied by means of a force application device in order to axially displace the inner plate carrier and the disconnect clutch device. The separating tongues are preferably arranged on a ring formed by the inner plate carrier, which ring serves to absorb the force of the leaf spring, wherein the separating tongues extend from the radially more inner side of the ring towards the radial inner side.
Furthermore, the inner plate carrier can have at least one and preferably a plurality of driving webs which interact positively with the first friction plate, so that a torque can be transmitted between the driving webs and the first friction plate.
The driver web is designed such that the edge centering and the axial bracing of the axially last friction disk, which is positioned on the side on which the hub element is arranged and is preferably a steel disk, are carried out more narrowly than the guidance of the remaining friction disks.
This embodiment has the advantage that the remaining friction disks can move relatively freely when the clutch device is disengaged, so that a disconnection with reduced wear of the clutch device can be achieved. The axially last friction disk prevents the driving web from being deformed by the action of a large centrifugal force at high rotational speeds, since it has a smaller play with respect to one or more driving webs.
The driving web extends substantially coaxially to the rotational axis of the clutch device. At least one pressure element is formed on at least one of the driving lugs at its end region facing away from the separating tongue, by means of which an axial force can be applied to the friction linings in order to press them against one another and thus transmit the torque in a friction-fitting manner. Accordingly, the axial displacement of the inner plate carrier and thus of the carrier plate and the pressure element causes the pressure element to be able to move away from the friction plates and thus reduces the axial pressure on the friction plates, so that a relative rotational movement between the respective friction plates can be carried out accordingly, and the clutch device is switched off. This means that the clutch device according to the invention can also be provided without additional pressure plates, since the required pressing force is transmitted to the plate package via the individual pressing elements.
In particular, the clutch device according to the invention is designed as a multi-disk clutch which can preferably be used in motor vehicles, but the use of the clutch device in passenger cars, trucks or also tractors should not be excluded. In an application as a clutch device for a motorcycle, it is preferably provided that the clutch device according to the invention is embodied as a wet clutch. The clutch device according to the invention is also embodied as a dual clutch or as a separating clutch of a hybrid module.
the clutch device according to the invention is therefore a low-cost design solution, in particular for a motorcycle clutch, which enables a relatively high torque transmission with a small number of design elements and a small design volume.
In addition, according to the invention, a drive train for a motor vehicle is provided, which has an engine, in particular an internal combustion engine, and a clutch device and a vehicle transmission according to the invention, wherein the clutch device is mechanically connected to the engine and the vehicle transmission.
Within the scope of the invention, the terms radial and axial always relate to the axis of rotation of the clutch device.

Fig. 1 shows a sectional view of a clutch device according to the invention;
Fig. 2 shows a perspective view of a leaf spring core;
Figure 3 shows a perspective view of the inner sheet carrier;
FIG. 4 shows a perspective view of the counter plate;
Fig. 5 shows a further sectional view of the clutch device according to the invention.
Detailed Description
The general construction of the clutch device according to the invention can be seen in particular in fig. 1. The clutch device shown here comprises, arranged about a common axis of rotation 1, an inner disk carrier 10 with a plurality of first friction disks 20 arranged in a rotationally fixed manner in relation thereto, and an outer disk carrier 30 with a plurality of second friction disks 40 arranged in a rotationally fixed manner in relation thereto.
The first friction plate 20 and the second friction plate 40 together form a plate pack 50.
The clutch device furthermore comprises a hub element 60, which is connected in a rotationally fixed manner to the inner plate carrier 20 by means of a plurality of leaf springs 70. A further connection between the hub element 60 and the inner plate carrier 20 is realized by means of a stepped screw 80.
Furthermore, the clutch device comprises a counter plate 100, which is centered by the stepped screw 80. The counter plate 100 is connected in a rotationally fixed manner to a driven device, for example a transmission input shaft. Furthermore, the clutch device comprises a release bearing 120 and a central nut 110, which is axially displaceable, in such a way that it is arranged centrally on the axis of rotation 1. On the side axially opposite these components, the clutch device comprises a bushing 140 on which the damping unit 130 is arranged. The damping unit 130 is connected in a rotationally fixed manner to the outer plate carrier 30 and has the function of a torsion spring with friction, which damps load-changing impacts in order to protect the connected drive train. The sleeve 140 serves to compensate for the difference in rotational speed between the damping unit 130 and the connected transmission input shaft.
The torque to be transmitted by the clutch device or the rotational movement to be transmitted is introduced into the damping unit 130 and transmitted by the latter to the outer plate carrier 30, so that the second friction plate 40 is set in rotation or a torque is also applied to it. In the normally closed state of the clutch device, the second friction disk 40 transmits a torque in a friction-fit manner to the first friction disk 20, from which it transmits a torque in a form-fitting manner to the inner disk carrier 10.
From which torque is transmitted in turn via the leaf spring 70 to the hub element 60. The hub element has a centrally arranged internal toothing 62 for the positive transfer of torque to a driven device, for example a transmission input shaft, not shown here.
when the central nut 110 or the release bearing 120 is moved axially, the inner disk carrier 10 is pressed downward in this not shown position of the clutch device against the axial force generated by the leaf spring 70, so that the axially acting contact force between the friction disks 20, 50 is reduced, the torque flow through the clutch device is reduced or interrupted and the clutch device is accordingly opened.
Fig. 2 shows the design according to the invention of the clutch device. The so-called leaf spring core 90 shown here comprises the inner plate carrier 10, the hub element 60, the leaf spring 70 arranged therebetween and the stepped screw 80.
It can be seen that the leaf springs 70 are fixed to the hub element 60 by means of respective first ends 71 and to the inner sheet carrier 10 by means of respective second ends 72. In the embodiment shown here, the fastening on the inner plate carrier 10 at the second end 72 is effected by means of riveting, wherein a corresponding rivet extends through the leaf spring riveting hole 16 in the inner plate carrier 10.
The mechanical fastening of the first end 71 of the respective leaf spring 70 takes place by means of a stepped screw 80, which in this case acts as a rivet, thus realizing a riveted connection 91.
The stepped screw 80 is guided through the passage opening 11 in the inner plate carrier 10 and forms, on the side opposite the connection of the leaf spring 70, a screw head 81 which is thicker in the radial direction than a screw shank 82 of the respective stepped screw 80, so that a translational movement of the stepped screw 80 through the passage opening 11 towards the hub element 60 is prevented.
This results in the leaf spring core 90 shown in fig. 2 being available in the prestressed state, so that it can be easily integrated into a drive train with an axially reduced size.
Fig. 3 shows a specific structural configuration of the inner sheet carrier 10 as a separate component. It can be seen that the inner plate carrier 10 has a substantially radially extending annular portion 12, on the radial inside of which a plurality of separating tongues 13 are arranged, on which a force from the central nut 110 or the separating bearing 120 can act axially.
Furthermore, the inner sheet carrier 10 comprises coaxially arranged driving webs 14 which are connected to the ring segment 12. On the side facing away from the ring part 12, the pressing element 15 is connected to the driving web 14, in this case in the form of a web.
Due to the force action of the leaf spring 70, these pressure elements 15 apply a corresponding axial force to the sheet pack 50. With this simplified structure, the clutch device according to the present invention does not require the provision of a pressure plate.
fig. 4 shows a perspective view of a counter plate 100 with a bore 101 which corresponds at least in some regions complementarily to the shape and size of the cross section of the bolt head 81 of the stepped bolt 80. This makes it possible, at least when the leaf spring core 90 is assembled, to position it with respect to the counter plate by means of the bolt head 81 via the bore 101 of the counter plate 100 and thus also with respect to the outer plate carrier 30.
Furthermore, the counter plate 100 comprises radially inwardly extending centering tongues 102 for abutting against the release bearing 120 and thus for centering the counter plate 100.
the recess 104 serves to accommodate the rivet connection of the stepped screw in order to avoid a collision with the counterplate.
In this case, the bore 101 and the centering bore 104 are arranged in the screw connection surface 103 of the counter-pressure plate 100.
Fig. 5 shows the clutch device according to the invention again in different details of the individual described components.
The design according to the invention of the clutch device makes it possible to produce individual components, like for example the hub element 60, as shown in fig. 1, with relatively little effort. Hub element 60 includes a centrally disposed hub sleeve 61 having an internal tooth 62 disposed therein, and a hub flange 63 connected to hub sleeve 61. It is proposed that at least one of the two components hub sleeve 61 and hub flange 63 is made of a softer material than the other component, so that hub sleeve 61 and hub flange 63 can be locked to one another. In order to produce a suitable contour of hub sleeve 61 and hub flange 63 by means of locking, they can each have a toothing on their sides facing one another, which is implemented complementarily to the toothing of the respective other component. In this way, the hub element can be provided in a cost-optimized manner.
The clutch device according to the invention also provides a simple and cost-effective measure against the effect of the widening of the driving webs 14 of the inner plate carrier 10 due to centrifugal forces, in that: a smaller radial play exists between the axially last friction disk 21, which belongs to the first friction disk, which is preferably made of steel, and the driver web 14 than between the driver web 14 and the remaining friction disks 20.
Thus, with the invention proposed here, a clutch device is provided which ensures centering of the leaf spring core 90 with respect to the counter plate 100 in a simple manner during assembly and which simplifies assembly due to the possibility of pretensioning of the leaf spring core 90.
