Description

The present invention relates to a coupling for coupling a drive shaft of an automotive engine with a first transmission input shaft of a motor vehicle transmission with a first part clutch for coupling the drive shaft with the first transmission input shaft. In particular, the invention relates to a dual clutch with a first transmission input shaft and a second transmission input shaft of a motor vehicle transmission having a first part clutch for coupling the drive shaft with the first transmission input shaft and a second part clutch for coupling the drive shaft with the second transmission input shaft.

From the EP 1 524 446 A1 is a double clutch for coupling a drive shaft of an automotive engine with a first transmission input shaft and a second transmission input shaft of a motor vehicle transmission known.

In the previously unpublished DE 10 2014 206 066.4 a dual clutch for coupling a drive shaft of an automotive engine with a first transmission input shaft and a second transmission input shaft of a motor vehicle transmission will be described. In this case, intermediate plates are proposed, which are arranged between the friction linings of a respective clutch disc. Upon actuation of the respective partial clutch of the double clutch, the corresponding pressure plate is moved towards a counter plate, so that the interposed clutch disc is acted upon by the friction linings with a torque. With the help of the respective intermediate plate, it is possible to provide two further friction linings for pressing friction linings of the associated clutch disc, so that the number of friction surfaces of the respective part clutch can be correspondingly increased with the intermediate plate. Due to the increased number of friction surfaces, a correspondingly increased torque can be transmitted. Additionally or alternatively, the applied to the respective pressure plate contact pressure can be reduced in order to transmit a certain maximum torque can still. Due to the smaller outer radius, the moment of inertia of the respective sub-coupling can be reduced and radial space can be saved.

Regarding the details of the double clutch is unpublished on you DE 10 2014 206 066.4 Reference, the contents of which are fully incorporated in this document to that extent.

In the previously unpublished DE 10 2014 212 783.1 is proposed a clutch disc with double-sided friction linings. Such clutch plates can advantageously in the double clutch according to DE 10 2014 206 066.4 be used.

Regarding the details of the clutch disc is unpublished on you DE 10 2014 212 783.1 Reference, the contents of which are fully incorporated in this document to that extent.

Next is from the DE 10 2010 024 460 A1 It is known that clutch discs have spring elements between the metallic carrier and the generally non-metallic friction lining. These spring elements are used to ensure a specific moment structure.

The object of the invention is to at least partially solve the problems described with reference to the prior art and, in particular, to provide a coupling which has an even more compact design and in which, moreover, the number of components is further reduced. Next, an intermediate plate should be specified, which is particularly suitable for use in the coupling according to the invention.

These objects are achieved with a coupling according to the features of independent claim 1 and with an intermediate plate according to the features of independent claim 10. Further advantageous embodiments are given in the dependent formulated claims. It should be noted that the features listed individually in the dependent claims can be combined in any technologically meaningful manner and define further embodiments of the invention. In addition, the features specified in the claims are specified and explained in more detail in the description, wherein further preferred embodiments of the invention are shown.

wobei die erste Zwischenplatte eine linke Zwischenplatte und eine rechte Zwischenplatte aufweist, wobei zwischen linker Zwischenplatte und rechter Zwischenplatte zumindest ein Federelement angeordnet ist. The invention relates to a coupling for coupling a drive shaft of a motor vehicle engine with a first transmission input shaft of a motor vehicle transmission with

• A first partial clutch for coupling the drive shaft to the first transmission input shaft, wherein the first partial clutch, a first counter-plate, a relative to the first counter-plate axially displaceable first intermediate plate and a relative to the first counter-plate and the first intermediate plate axially displaceable first pressure plate for pressing first friction linings the first clutch plate between the first counter-plate and the first intermediate plate and between the first intermediate plate and the first pressure plate,

wherein the first intermediate plate has a left intermediate plate and a right intermediate plate, wherein between the left intermediate plate and the right intermediate plate at least one spring element is arranged.

In particular, the spring element and thus the intermediate plate is compressible in an axial direction. In particular, the spring element is a spacer between left intermediate plate and right intermediate plate, so that the intermediate plates are spaced from each other by a fixed distance.

In particular, friction linings of a clutch disc are thus arranged on both sides of the intermediate plate. The first part of the disc disc is arranged with particular two-sided friction linings between counter-plate and intermediate plate and the second part disc the same clutch disc with particular two-sided friction linings between intermediate plate and pressure plate.

In any case, therefore, the intermediate plate is formed with spaced apart (left and right) intermediate plates. The division of the intermediate plate into a left and a right intermediate plate leads to the creation of two additional surfaces, through which heat can now be released. Thus, the thermal stability of the intermediate plate and the double clutch can be further increased.

• • einer zweiten Teilkupplung zum Kuppeln der Antriebswelle mit der zweiten Getriebeeingangswelle, wobei die zweite Teilkupplung eine zweite Gegenplatte, eine relativ zur zweiten Gegenplatte axial verlagerbare zweite Zwischenplatte und eine relativ zur zweiten Gegenplatte und zur zweiten Zwischenplatte axial verlagerbare zweite Anpressplatte zum Verpressen von zweiten Reibbelägen einer zweiten Kupplungsscheibe zwischen der zweiten Gegenplatte und der zweiten Zwischenplatte sowie zwischen der zweiten Zwischenplatte und der zweiten Anpressplatte aufweist,

wobei zumindest eine von der ersten und zweiten Zwischenplatte eine linke Zwischenplatte und eine rechte Zwischenplatte aufweist, wobei zwischen linker Zwischenplatte und rechter Zwischenplatte zumindest ein Federelement angeordnet ist, so dass die Zwischenplatte in einer axialen Richtung komprimierbar ist. In particular, the clutch is a double clutch for coupling a drive shaft of an automotive engine with a first transmission input shaft and a second transmission input shaft of a motor vehicle transmission with

• A first partial clutch for coupling the drive shaft to the first transmission input shaft, wherein the first partial clutch, a first counter-plate, a relative to the first counter-plate axially displaceable first intermediate plate and a relative to the first counter-plate and the first intermediate plate axially displaceable first pressure plate for pressing first friction linings the first clutch plate between the first counter-plate and the first intermediate plate and between the first intermediate plate and the first pressure plate,
• A second sub-clutch for coupling the drive shaft to the second transmission input shaft, the second sub-clutch having a second counter-plate, a second intermediate plate axially displaceable relative to the second counter-plate and a second pressure plate axially displaceable relative to the second counter-plate and the second intermediate plate for pressing second friction linings second clutch plate between the second counter-plate and the second intermediate plate and between the second intermediate plate and the second pressure plate,

wherein at least one of the first and second intermediate plates has a left intermediate plate and a right intermediate plate, wherein between left intermediate plate and right intermediate plate at least one spring element is arranged so that the intermediate plate is compressible in an axial direction.

At least one of the intermediate plates thus comprises at least a left intermediate plate and a right intermediate plate and arranged therebetween spring elements. Thus, the intermediate plate is compressible, in particular in the axial direction and thus realized a pad suspension of the intermediate plate.

The suspension of the intermediate plate allows in particular further that the lining suspension of the clutch discs (lining suspension of the friction linings between counter-plate and intermediate plate and between intermediate plate and pressure plate) can be omitted. Thus, the (two) pad springs of the friction linings can be optionally replaced by the (one) suspension of the intermediate plate. This space can be saved in the axial direction or the mass of the thermally stressed intermediate plate can be increased. Furthermore, the number of components of the double clutch is reduced.

In a pad suspension of the clutch disc, these are connected in series (pad suspension of the friction linings between counter-plate and intermediate plate and between intermediate plate and pressure plate). Here it is possible that during operation of the clutch not both pad springs spring in at the same time, but one after the other. This has the consequence that the torque to be transmitted (especially at low torques) is initially transmitted only partially or more strongly via a part of the disc disc. This is an unfavorable force-displacement characteristic, in particular with respect to geometrically induced torque fluctuation before.

The arrangement of a lining suspension in the intermediate plate allows that there is always the same force-displacement characteristic for each partial friction disc (clutch disc) per partial clutch.

Next can be compensated by the arrangement of a lining suspension in the intermediate plate tolerances or geometric errors of the clutch discs. In contrast to rigid intermediate plates thus the error of a first part of the disc disc disc is not transmitted to the second part of the disk disc disc.

Preferably, at least one (metallic) spring element of the intermediate plate is arranged between a metallic left intermediate plate and a metallic right intermediate plate. Thus, the life is further increased compared to pad springs in clutch discs, since the (metallic) spring elements in clutch discs can work into the non-metallic friction linings.

In particular, the first intermediate plate and the second intermediate plate are each composed of a left intermediate plate and a right intermediate plate, each having at least one, arranged therebetween spring element.

At least one of the friction linings of the clutch disks preferably has a lining suspension.

In particular, at least the first left intermediate plate is mounted on at least one leaf spring on the first counter-plate and / or the second left intermediate plate on at least one leaf spring on the second counter-plate

In particular, the at least one leaf spring extends substantially in the circumferential direction and tangentially to the intermediate plate and the counter-plate. With the help of the leaf spring, the double clutch can be radially centered on the drive shaft. The leaf spring may further provide axial flexibility in the nature of a flexplate to compensate for and / or dampen axial oscillations and / or wobble of the drive shaft. The at least one leaf spring also transmits torques between the connected plates (here counter plate and intermediate plate). The torques between the left intermediate plate and the right intermediate plate are transmitted through the at least one spring element. Furthermore, the at least one leaf spring serves to position the interconnected plates along the axial direction.

Preferably, the at least one leaf spring is a stack of leaf springs. Preferably, a plurality of leaf springs are arranged in the circumferential direction, in particular at equal distances from each other.

In particular, (exclusively or in addition to the storage of the first left intermediate plate on the first counterplate), the first right intermediate plate is mounted on the second counterplate via at least one leaf spring.

In particular, (in addition to the storage of the first left intermediate plate on the first counter-plate), the first right intermediate plate is supported by leaf springs on the first counter-plate.

In particular, the leaf springs are respectively fixed to a fixed in the axial direction component of the coupling (ie instead of attachment to a counter-plate), so that the intermediate plates are each mounted opposite this fixed in the axial direction component. This fixed in the axial direction component is in particular a clutch cover.

In particular, first and second counter-plate are combined in one component.

The invention further relates to an intermediate plate for a clutch / dual clutch, in particular for a clutch / double clutch according to the invention, wherein the intermediate plate has at least one left intermediate plate and a right intermediate plate and at least one, arranged therebetween spring element

In particular, the spring element and thus the intermediate plate is compressible in an axial direction. In particular, the spring element is a spacer between left intermediate plate and right intermediate plate, so that the intermediate plates are spaced from each other by a fixed distance.
