Description

The present invention relates to a multiple clutch arrangement for transmitting a torque with a carrier rotatably arranged about a rotation axis, a radially inwardly of the carrier about the rotation axis rotatably arranged first sub-coupling, in particular a first multi-plate clutch, a first actuating assembly for actuation, preferably for frictional engagement, the first Partial coupling, wherein at least a first return element on the first actuating assembly has a restoring force to disengage / open the first part clutch, a radially rotatable within the carrier about the rotation axis arranged second sub-coupling, in particular a second multi-plate clutch and at least one second actuation assembly for actuation, preferably for frictionally closing, the second sub-clutch, wherein a second return element on the second actuating assembly has a restoring force to the second sub-clutch from to couple / open.

From the prior art multiple clutch assemblies and torque transmission devices are known which use disc springs as return elements. These disc springs, which act as air springs, are made in one piece due to their operation and are inserted during assembly in the multiple clutch assembly.

In the German patent application DE 10 2017 008 624 A1 a torque transmitting device is disclosed in which a force application point of the return means / return element is arranged radially outside of an actuating finger of an actuating assembly.

A disadvantage of multiple coupling arrangements according to the prior art, however, is that no further components or components can be centered on the disc springs and that just as few other components can be fixed to the disc spring. During assembly, a high level of awareness regarding unwanted loosening of the disc springs and falling out is also required. A centering, in particular of pressure pots of the respective coupling, if necessary, must take place via another / other component.

It is therefore the object of the invention to avoid or at least reduce the disadvantages of the prior art and in particular to provide a multiple-clutch arrangement and a hybrid module which has a compact design, in particular a small axial length, ensures easy installation, is low in production and provides a centering and / or anti-rotation of other components or components.

The object of the invention is achieved in a generic multiple clutch assembly according to the invention that the first return element is designed as a helical spring / helical compression spring and the second return element as a plate spring. The fact that the first return element is designed differently from the second return element, the advantages of the two return elements can be combined. The helical compression spring or the helical compression springs have the advantage of good handling and a very good centering possibility. The disc springs, however, have a very small axial space. The combination with the first return element as a helical spring and the second return element as a plate spring thus has a good handling for assembly, a good centering function for other components and yet a small axial space.

Advantageous embodiments are claimed in the subclaims and are explained below.

Preferably, the actuating assembly may include a pressure cup provided for axially displacing and actuating the respective partial clutch, which is designed to apply a contact force to a respective, for example, first (steel) blade of the respective partial clutch via a pressure ring and / or one or more actuating fingers. Such an actuating assembly is well implemented in terms of production and has a safe operation of an operation.

In a preferred embodiment, the at least one helical spring may have approximately the same radial distance from the axis of rotation as the first actuating finger. This configuration allows direct power flow and the resulting spring force of the coil spring can be directly supported without force redirection. As a result, a deflection of components, which supports the coil spring, is reduced.

According to one embodiment of the invention, it is expedient if the multiple-clutch arrangement has a carrier ring (a base plate) which is fastened to the carrier, wherein the at least one helical spring is supported on the carrier ring in the axial direction. The coil spring can therefore be indirectly supported on the support ring on the carrier. About the support ring, the at least one coil spring can be positioned in particular, at the same time a mounting and manufacturing is simplified.

Preferably, the support ring has an opening / a passage / a window through which the first actuating finger is movably guided in the axial direction and centered with respect to the axis of rotation. The support ring, which is attached to the carrier and centered by this and held against rotation, in turn, the first actuating finger, which is actuated in the axial direction, lead and center.

According to one aspect of the invention, the support ring has on its radial inner side a recess / a gate in the radial direction, in which a second actuating finger of the second actuating assembly protrudes and is movably guided in the axial direction. The carrier ring, which is fixed relative to the carrier, in turn serves as a guide of the second actuating finger and thus the second actuating assembly.

It is preferred if the recess of the carrier ring is designed such that it centers the second actuating finger relative to the (common) axis of rotation (radial centering) and in the circumferential direction to the carrier ring against rotation (rotationally fixed) holds. The support ring is also used in this embodiment, the centering and rotation of the second actuating finger and thus the second actuator assembly. This can be done in particular over alternating recesses and projections in the radial direction.

In particular, the plate spring can be supported on the one hand on the support ring and on the other hand on a second pressure pot of the second actuating assembly in the axial direction. The plate spring is therefore supported on the one hand indirectly via the support ring on the carrier and on the other hand on the second pressure pot. When axial displacement of the second pressure pot and a power transmission to the second actuating finger builds up a restoring force by the support on the support ring and thus the support by the plate spring.

According to a further embodiment, the helical spring can be arranged radially further outward with respect to the plate spring. This special arrangement allows a particularly compact design, since the coil springs can be arranged in approximately the same axial position to the (radially inner) plate spring.

Preferably, a support ring is attached to the first pressure pot in particular rotationally fixed, on which the coil springs are supported in the axial direction, wherein the support ring for positioning the coil spring has at least one geometric position marker. The support ring favors a mounting process.

Preferably, the support ring also has an opening / a passage / a window through which the first actuating finger is movable in the axial direction and guided against rotation in the circumferential direction.

In a preferred embodiment, a plurality of circumferentially, in particular evenly, distributed first actuating fingers may be provided, wherein between two first actuating fingers in each case a helical spring is arranged. Such a configuration is of particular advantage, since the coil springs and the first actuating fingers have a same radial distance from the axis of rotation and can initiate a force uniformly over the circumference.

Also, preferably, a plurality of distributed over the circumference second actuating finger may be provided, which in each case project into the corresponding recesses of the carrier ring. The support ring centered on the one hand, the second actuating finger and thus the second actuator assembly and on the other holds the support ring against rotation.

In particular, the carrier ring can be designed as a sheet metal component in the form of a carrier plate with preferably a radially outer collar for stiffening and centering on the carrier. An education in the form of a carrier sheet is particularly simple and inexpensive to manufacture.

According to one embodiment of the invention, the plate spring or the plate springs may have a recess through which the second actuating finger protrudes in the axial direction. Thus, the plate spring is centered by the second actuating finger and held against rotation.

According to a particular embodiment, the support ring may be designed as a sheet metal component in the form of a support plate. An education in the form of a support plate is particularly simple and inexpensive to manufacture.

The invention also relates to a hybrid module for a vehicle with such a multiple clutch. By using a multiple clutch arrangement according to the invention, a compact and easy-to-handle hybrid module can be provided.

In other words, the invention relates to a Lüftfederanordnung for axial double clutches (or multiple clutch assemblies) with at least one plate spring and a compression spring package (coil spring "package" or a coil spring). For the ventilation of the one (first) partial clutch is used as a compression spring package, for the other (second) Partial coupling the diaphragm spring used. In particular, the compression spring assembly is arranged radially on the outside of the (multiple) clutch and is supported between the outer disk carrier (ALT) / rotor carrier / carrier and a first pressure pot. Here are the advantages of the compression spring package (handling and centering) and the diaphragm spring (low axial space) combined. The individual compression springs (coil springs) are arranged between two sheets, which serve the connection (axially) within the (multiple) coupling. The outer plate carrier facing sheet (base plate / support ring) is formed such that it projects radially inwardly into the (multiple) coupling and serves both the centering of the two pressure cups and the support of the second plate spring.

It is therefore intended to optimize a hybrid module, in particular with regard to a radial installation space as well as the handling / handling during installation. In addition, a centering of both the first printing and second printing to be realized. For the release of the first part clutch so the compression spring package (coil spring package) and the plate spring is used for the second part clutch. The compression spring assembly has individual compression springs (coil springs), which are preferably distributed over the circumference that they sit in the "interstices" of the passages of a first pressure ring (first actuator assembly). The (pitch circle) diameter on which the compression springs are mounted or the (radial) distance to the axis of rotation is located in particular on (radial) height of the outer disk carrier (carrier), which has the advantage that the resulting spring force, directly on Outer plate carrier, without power diversion, is supported. This reduces the deflection of the base plate (carrier ring). The base plate has radially outside in particular a collar which serves on the one hand the centering of the (coil) spring assembly on the outer disk carrier and on the other hand increases the rigidity of the base plate / sheet / carrier ring. Towards the axis of rotation, or radially inwards in relation to the collar, there are, distributed over the circumference, preferably windows or openings through which the first pressure ring can reach. These windows also serve to center the first pressure ring. Next radially inward are on the base plate outbreaks or recesses that are designed or designed so that they serve on the one hand the centering and on the other hand, the rotation of the second pressure pot. Adjacent to this are pads for the second diaphragm spring attached.

The second plate spring has a radially inner "force edge" (support section) and radially outer fingers (support fingers). This makes it possible that the plate spring can lie radially within the second pressure pot and only pass through the fingers radially outward. Thus, the plate spring can be supported on the provided on the base plate supports while the pressure pot centered on the corresponding outbreaks.

In order to be able to assemble the compression spring package simply, a (second) support plate is preferably mounted (axially) opposite the base plate. In turn, in particular windows or openings are embedded / introduced, through which the pressure fingers (actuating fingers) can reach through.

The centering of the first and second pressure pots takes place in particular via the base plate of the compression spring package. The rotation of the second pressure pot is in particular also on the base plate. The diaphragm spring can be supported mainly on the base plate.

Due to this arrangement, a compact and easy-to-handle air spring device or multiple clutch arrangement and an optimized hybrid module is to be realized.

In other words, the invention relates to a torque transfer device (multiple clutch assembly). According to the invention, the torque transmission device for transmitting torque between a drive element and an output element, with at least one arranged around a rotation axis first clutch assembly (first sub-clutch) with a first clutch input and a frictionally engageable with this via a first Reibpaket and connectable to a first transmission input shaft first A clutch output, a first actuator (first actuating assembly) for actuating the first clutch assembly having at least a first actuating finger and a first pressure pot, and a first return element for effecting a restoring force on the first actuating element, wherein the force introduction point of the first restoring element radially to the axis of rotation of the first coupling assembly on Height of the first actuating finger for actuating the first coupling assembly is arranged. As a result, the resulting spring force of the return spring can be supported directly without power redirection at the clutch input.

A particularly preferred embodiment of the invention is characterized in that for supporting the first return element at the first coupling input, a first support element (support ring) is provided which is non-rotatably connected to the first coupling input.

In a particularly advantageous embodiment, the support element has a bent collar. On the one hand, the collar serves to center the restoring element on the first coupling inlet and on the other hand increases the rigidity of the supporting element.

Advantageously, the support element is designed as a bent sheet metal component.

In a further particularly advantageous embodiment, the first support element has a recess (window) through which the first actuating finger can be guided. By such a recess, a centering of the first actuating element with its first actuating finger and its first pressure pot is particularly easy.

Furthermore, the support element may have radially on its inner circumference outbreaks (recesses) through which a second actuating finger of a second actuating element (second actuating assembly) of a second coupling assembly (second sub-coupling) can pass.

Preferably, the outbreaks are designed so that a radial centering and anti-rotation in the circumferential direction of the second actuating finger of the second actuating element can take place.

Furthermore, the first support element bearing areas for supporting a second return element for effecting a restoring force on a second actuating element of a second coupling assembly.

Particularly preferably, a second support element (support ring) is provided for supporting the first return element on the pressure pot, which is non-rotatably connected to the pressure pot.

That means on the radial outside of the carrier 4 For example, windings or magnets are arranged with the carrier 4 are rotatably connected and when exposed to electricity or in interaction with a magnetic field on the carrier 4 transmit a corresponding torque. The radial outside of the carrier 4 is designed in the form of a cylinder whose radius along the axial direction is the same is. Radial inside the vehicle 4 is, also around the axis of rotation 3 rotatably arranged, a first part clutch 5 arranged in the form of a multi-plate clutch. A first actuation assembly 6 actuates the first part clutch 5 by breaking the first part clutch 5 presses and thus causes a frictional connection. The first part clutch 5 is a in normal position or normal state opened clutch, as several first reset elements 7 on the first actuator assembly 6 affect a restoring force to the first part clutch 5 disengage or open.

Also, the multiple clutch assembly 1 a radially inside of the carrier 4 around the axis of rotation 3 rotatably arranged further, second part clutch 8th in the form of a multi-plate clutch. The second part clutch 8th has approximately the same radial distance to the axis of rotation 3 on and is in the axial direction to the first part clutch 5 added. A second actuator assembly 9 actuates the second part clutch 8th , where analogously a second return element 10 on the second actuator assembly 9 a restoring force affects the second part clutch 8th disengage or open. The second part clutch is open in normal position or normal state clutch, since at least the second return element 10 on the second actuator assembly 9 a restoring force impacted to the second part clutch 8th disengage or open. In 1 is the first and second partial clutch 5 . 8th shown in a disengaged or opened state.

In contrast to the prior art known in the present invention is the first return element 7 as a coil spring or helical compression spring 11 and the second return element 10 as a plate spring 12 executed. The combination of the return elements as a helical spring 11 and as a plate spring 12 combine the advantages of both forms, namely on the one hand by means of coil springs 11 a good handling / handling and on the other by the diaphragm spring 12 a small space in the axial direction. For ventilating the first part clutch 5 So is the coil spring 11 as the first return element 7 provided and only by applying a force against the restoring force of the coil spring 11 becomes the first part clutch 5 engaged and closed. The same applies to the diaphragm spring 12 as a second return element 10 ,

The coil springs 11 are around the axis of rotation 3 circumferentially evenly distributed and in the axial direction (in the direction of the axis of rotation 3 ), so that the restoring force of the coil springs 11 also circumferentially act evenly in the axial direction and the coil springs 11 a restoring force in the axial direction relative to the carrier 4 to bear on which they support themselves.

The first actuator assembly 6 has for axial displacement and actuation of the first part clutch 5 a first pressure pot 13 on, which is designed, over several first actuating fingers 14 , which are circumferentially equally distributed and project in the axial direction, on a first steel plate 15 of several slats 16 or outer plates 16 the first part clutch 5 , which is designed as a multi-plate clutch to apply a contact force to the first part of the clutch 5 or the first multi-plate clutch frictionally close and engage.

The diameter on which the coil springs 11 opposite the axis of rotation 3 are arranged, is approximately the same diameter, on which the first actuating finger 14 are arranged. Specifically, in this preferred embodiment, as seen in the circumferential direction, coil springs alternately 11 and first actuating fingers 14 intended. In other words, change in the circumferential direction with approximately the same radial distance, the coil spring 11 and the first actuating fingers 14 from. Both the coil springs 11 as well as the first actuating fingers extend in the main in the axial direction. The radial distance to the axis of rotation 3 that the coil springs 11 In addition, is approximately the same radial distance as to the radial outside of the carrier 4 or the outer disk carrier of the outer disk 16 the first part clutch 5 , This has the advantage that the resulting spring force or restoring force of the coil springs 11 as directly as possible to the carrier 4 is supported with the smallest possible lever arm in the radial direction, so that the restoring force mainly applies a tensile-compressive force in the longitudinal axis direction of the components.

Analogous to the first actuator assembly 6 has the second actuator assembly 9 for axial displacement and actuation of the second part clutch 8th a second pressure pot 17 which is designed to have a plurality of circumferentially distributed second actuating fingers 18 of the second pressure pot 17 , which extend in the axial direction, on a first steel plate 15 of several slats or outer slats 16 the second part clutch 8th , which is designed as a multi-plate clutch to apply a contact force, so as to the second part of the clutch 8th or the second multi-plate clutch frictionally close and engage. The first actuating fingers 14 facing the second actuating fingers 18 a multiple of the axial extent, since the second pressure pot 17 seen in the axial direction between the first pressure pot 13 and an end portion of the first operating finger 14 lies.

A seen in the radial direction inside portion of the single plate spring 12 lies on the second pressure pot 17 and squeezes the second pressure pot 17 and thus the second actuating fingers 18 in the open position of the second part clutch 8th , The second pressure pot 17 and the second actuating fingers 18 are integrally formed, wherein the second pressure pot 17 a ring structure 19 with curvature in the axial direction, but extending in the main thing in the radial direction. The second actuating fingers 18 stand transversely to the domed ring structure 19 in the axial direction and the tips of the second actuating fingers 18 act on the first steel plate 15 the outer lamellae 16 on.

The first part clutch 5 and the second part clutch 8th seen in the axial direction one behind the other at approximately the same radial height or at approximately the same radial distance from the axis of rotation 3 arranged. The coil springs 11 , which as the first return element 7 on the first part clutch 5 act, but are opposite the diaphragm spring 12 not arranged with the same radial distance but radially further out. Analogous to the reset elements 7 . 10 are also the first actuating fingers 14 opposite the second actuating fingers 18 arranged radially further outward.

While the partial clutches 5 . 8th radially inside the carrier and in 1 As seen on the left, both are actuating assemblies 6 . 9 spaced in the axial direction to the partial clutches 5 . 8th in 1 seen arranged to the right. The first part clutch 5 is in 1 seen farther left than the second part clutch 8th arranged. As previously explained, the first actuating fingers extend 14 opposite the second actuating fingers 18 For this reason, many times in the axial direction. The first actuating fingers 14 stand for an actuation or for the transmission of a contact force in each case by respective passage openings 20 the second part clutch 8th , seen in the axial direction between the first part clutch 5 and the first pressure pot 13 is arranged through. The first pressure pot 13 remote or the first steel plate 15 the first part clutch 5 facing end of each formed in the form of a metal strip first actuating finger 14 , Has a radially inwardly bent end 21 on. A section of the bent end 21 lies on the first steel lamella 15 radially in the middle. Thus, a central and optimal force on the first part clutch 5 guaranteed in the form of multi-plate clutch.

The second actuating fingers 18 of the second pressure pot extend in a straight line in the axial direction and also press centrally on the first steel plate 15 the slats 16 the second part clutch 8th , Seen in the radial direction are the second actuating fingers 18 opposite the first actuating fingers 14 further inside.

The multiple clutch arrangement 1 also has a carrier ring 22 on that on the carrier 4 is attached, rotates with this accordingly and a kind of housing cover of the part clutches 5 . 8th of the carrier 4 represents. The carrier ring 22 is designed rotationally symmetrical and has in the circumferential direction alternately an opening / a window 23 and a support projection 24 in the form of a spherical curvature in the axial direction, the diameter of which is slightly smaller than the diameter of the helical spring 11 , The coil spring 11 thus surrounds the spherical curvature of the support projection 24 and is prepositioned by this. The window 23 are designed in the form of (through) slots in the circumferential direction, through which the first actuating fingers 14 round stand. The window 23 serve to center the first actuating finger 14 and their rotation.

Seen in the axial direction is opposite to the carrier ring 22 or to the wearer 4 and in 1 seen on the right side a support ring 25 provided, attached to the first pressure pot 13 supported in the axial direction. The coil springs 11 So are seen in the axial direction between the carrier ring 22 and the support ring 25 , Both the carrier ring 22 as well as the support ring 25 are designed as sheet metal part and have the axis of rotation 4 as a common axis of rotation 3 , The coil springs 11 So indirectly rely on the support ring 22 on the one hand to the carrier 4 and on the other hand indirectly via the support ring 25 at the first pressure pot 13 in the axial direction. By means of the support ring 25 The coil springs can be mounted well.

The carrier ring 22 , the carrier 4 facing and fixed to this, has a radially outer side collar 26 on, extending in the axial direction to the carrier 4 extends and the carrier 4 engages on the radially outer side outer wall, serves on the one hand a stiffening of the carrier ring 22 and on the other hand as centering of the carrier ring 22 on the carrier 4 , Thus, the carrier ring 22 who is attached to the carrier 4 around the axis of rotation 3 is centered, in turn serve as a centering of other components or components. The radially inwardly projecting section / radial section 27 of the carrier ring 22 takes over as described below with the help of the 5 is explained, the function of centering the first pressure pot 13 as well as the second pressure pot 17 , In addition, the radial section is used 27 the support of the diaphragm spring 12 ,

5 shows in a partial perspective view of the assembly of the carrier ring 22 , the coil springs 11 and the support ring 25 , At a radial inner circumference 28 of the carrier ring 22 are in Circumferential direction recesses 29 and projections 30 provided as guide grooves. These are designed so that they on the one hand the centering and on the other hand, the rotation of the second actuating finger 28 and thus the second actuator assembly 9 serve. In the circumferential direction adjacent to the recesses 29 or the projections 30 are alternately bearing areas for the diaphragm spring 12 intended.

The support ring 25 points, analogous to the carrier ring 22 , Window 31 on, through which the first actuating fingers 14 stand through (see 1 ). Also the plate spring 12 has recesses 32 on, through which the second actuating fingers 18 round stand. This will also the plate spring 12 over the second actuating fingers 18 centered and held against rotation. So you can say that starting from the carrier 4 , the carrier ring 22 As stated above, on the carrier 4 (about the axis of rotation 3 ) centered and guided against rotation, wherein the carrier ring 22 then followed by the centering and anti-rotation of the first actuating finger 14 by means of the windows 23 the first actuator assembly 6 centered and holds against rotation, and on the recesses 29 and projections 30 in geometric interaction with the second actuating fingers 18 of the second pressure pot 17 the second actuator assembly 9 centered and holds against rotation. In addition, the carrier ring serves 22 the axial support of both the coil springs 11 as well as the plate spring 12 ,

As in 1 shown is the multiple clutch assembly 1 as a triple clutch of the hybrid module 2 executed. The first and second partial clutch 5 . 8th are radially inside the common carrier 4 arranged. The multiple clutch arrangement 1 has in this embodiment a third partial clutch 33 for connecting or disconnecting a torque transmission of an internal combustion engine (not shown) with downstream drive train and is the first part clutch 5 and the second part clutch 8th upstream. By means of the third part clutch 33 can, depending on the desired operating condition, the internal combustion engine connected to the downstream drive train or disconnected. The third part clutch 33 , which is also designed in the form of a multi-plate clutch, is at the same axial position as the first part clutch 5 but disposed radially inwardly therefrom.
