Currently available hybrid modules that combine combustion engine mode and electric motor mode through coupling of the combustion engine to the vehicle's powertrain usually include an electric motor, a detachable clutch and its operating system, bearings, and housing components. and they connect the three main components to form one operable unit. The electric motor enables electric travel, increased power for combustion engine mode, and regeneration. A detachable clutch and its actuation system provide for engagement or disengagement of a combustion engine. If the hybrid module is combined with the double clutch in such a way that the hybrid module is positioned between the combustion engine and the transmission in the torque transmission direction, in the vehicle the combustion engine, the hybrid module, the double clutch including their operating systems, and the transmission are successively connected, or be placed next to each other.

A hybrid module positioned in this type is referred to as a P2 hybrid module. However, this arrangement sometimes causes significant mounting space problems that affect or make assembly difficult.

From DE 10 2009 059 944 A1 a hybrid module is known comprising a split clutch inside the rotor of an electric machine. The split clutches of the double clutch device are arranged next to the rotor of the electric machine and thus also to the split clutch in an axially offset manner. In this case, the separable clutches are interleaved with each other in the radial direction. The actuation systems for the individual clutches are arranged next to said clutches in an axially offset manner.

DE 10 2007 008 946 A1 teaches a multiple clutch for vehicles with a hybrid drive. In this hybrid module, the two friction clutches are arranged inside the space enclosed by the rotor of the electric machine. The available mounting space within the hybrid module is determined, crucially, through the electric machine used and its laminated sheet package.

The object of the present invention is to provide an insert module, a hybrid module and a powertrain for a motor vehicle, which, based on the background art, combines a small mounting space with the possibility of simple assembly or observance of small tolerances.

The task is achieved via an insert module according to the invention according to claim 1, via a hybrid module according to the invention according to claim 6, via a powertrain according to the invention according to claim 8, and This is solved by the method according to the invention for assembling a powertrain according to claim 9 .

A preferred implementation form of the hybrid module of the present application is specified in dependent claim 7 . A preferred embodiment of the method for assembling a powertrain is specified in dependent claim 10 .

The features of the claims may be combined in their own technically suitable form and manner, to which also may be added features in the descriptions and drawings in the following description, including supplementary embodiments of the invention. there is. The axial and radial direction indications relate to the common axis of rotation of the aforementioned device assemblies. Thus, the axial direction is oriented perpendicular to the friction surfaces of the disks.

The present invention relates to an insert module for placement in a hybrid module of a motor vehicle, the insert module comprising a substantially rotationally symmetric disk carrier and at least two clutch devices, in particular one separable clutch and one or more starting clutches, The clutch devices each comprise one or more disc packs, each of which one or more discs act on the driver device of the disc carrier, in particular the toothing and torque-resistant manner. ) is connected to The disk carrier has, substantially, the form of a hollow annular cylinder consisting of two hollow cylinders arranged rotationally symmetrically. Further, the driver devices are arranged in a space defined in the radial direction by the disk carrier on at least one of the sides of the hollow annular cylinder that are spaced apart in the radial direction and opposed to each other.

The insertion module of the present application includes inner disc carriers and outer disc carriers connected to the disc packs of the clutch devices, by means of which inner and outer disc carriers each clutch device has one or more outputs of the hybrid module to which the insert module is to be provided. It can be connected to the side and rotationally fixed method. Each inner or outer disc carrier comprises at least one axially extending through opening, whereby a radially protruding portion is formed within the rotor carrier which, in the assembled state of the insertion module, is seated radially on the disc carrier. Through openings of inner disc carriers or outer disc carriers in which a tool is axially for the purpose of applying a force with a radial component for a radial displacement of a locking element, in particular a spring ring. can pass through

The inner disk carriers and the outer disk carriers are arranged in such a way that they are each radially opposite to the common disk carrier.

In particular, in the assembled state of the insertion module, the locking member in or on the rotor carrier extends radially from the rotor carrier into the disc carrier, in particular radially inwardly into the first hollow cylinder 93 of the disc carrier. do.

The inner disk carriers or the outer disk carriers are rotatably arranged about a common axis of rotation, so that they can be arranged in such a way that they are axially aligned with one another in a defined angular position, whereby the tool Through-holes may pass through.

Besides the function of the through-holes and the tool inserted into them for radially displacing the locking-member, the through-holes and the tool are additionally, consequently, in a common disc carrier through axially inserting the clutch devices as a whole. In order to facilitate the assembly of the clutch devices in the inner disk carriers or the outer disk carriers, and accordingly the disks of the disk packs of the clutch devices and disposed on the inner or outer disk carriers are also interchangeable. It is used for relatively accurate positioning of the liver.

Clutch devices can be designed as wet clutches. In this case, the split clutch device is connected in particular to the input side of the hybrid module. Preferably, in addition to the split clutch, two partial clutch devices of a double clutch device are provided, the disc packs of which are connected with the output side of the hybrid module.

In this case, the torque-resistant application of the disks of the disk pack to the driver device can allow for axial displacement. For this purpose, the driver device is preferably designed as a plug-in toothing. In this case, the hollow annular cylinder is a body forming an outer surface with its inner hollow cylinder located radially opposite the inner surface of the outer hollow cylinder.

Thus, as a sub-assembly or group of sub-assemblies, an insert module that can be inspected from the outside of the hybrid module is provided, which is also referred to as a triple clutch if it accommodates three clutch devices. The advantage of such an insert module is, in particular, that almost all assembly steps and measurement procedures necessary for the manufacture of the insert module can be carried out outside the rotor of the electric machine of the hybrid module, for which the insert module is provided, in a reliable manner. It is based on the fact that all the geometrical proportions of the clutch devices relative to each other and to the disk carrier can be set to the respective intended actual dimensions, in the assembled state the dimensional accuracy is high or the assembly tolerances are small.

Also, in this way, the setting procedures in the clutch devices are performed relatively simpler and more accurately, respectively. Furthermore, the insert module according to the invention makes it possible to manufacture insert modules for several hybrid modules or rotor carriers, in which only the contours of the insert module can be integrated into the rotor carrier independently of place and time, the so-called "" In order to provide one unit as an "Add in", it only needs to be made suitable for the rotor carrier.

In particular, the disc packs of the two clutch devices are arranged in a manner offset from each other in the radial direction, and the driver devices are arranged such that, for connection with one or more discs of one disc pack, the two inner surfaces of the two hollow cylinders of the hollow annular cylinder are On the two inner surfaces facing each other and spaced apart in the radial direction while facing each other, they are disposed in a space defined in the radial direction by the disc carrier. In other words, the driver devices are arranged in a hollow annular cylinder chamber defined radially by a disk carrier on inner surfaces located opposite to each other in the radial direction, to which disc packs are connected in a rotationally fixed manner, and then As a result, the disk packs are connected to the inner faces located opposite to each other.

In a further preferred embodiment, an additional clutch device is arranged axially next to the clutch device of one of the two clutch devices, in which additional clutch device likewise one or more discs are connected to the disc pack of the axially adjacent clutch device. One or more discs are also placed on the driver device on the inner surface of the hollow cylinder placed thereon. In other words, the disc packs of the third clutch device have, up to the common rotational axis of the clutch devices, a spaced distance such that the disk packs of the axially adjacent clutch devices overlap each other when viewed in the radial direction. In this case, the disks of both disk packs are connected in a rotationally fixed manner with the driver devices there on the same side of the same hollow cylinder.

Despite the arrangement of a three-disk pack, the insertion module according to the invention offers the advantage of simple handling, in particular during assembly on the assembly line and during insertion of the hybrid module to be manufactured into the rotor carrier, whereby assembly is simplified. It can be done in a way and certainly manually, or it can be automated.

In particular, the disc packs of the first part clutch device and the second part clutch device of the double clutch device are arranged on the inner surface of the outer hollow cylinder, and the disc packs of the split clutch device are arranged on the outer surface of the inner hollow cylinder. The disks of the disk packs on the faces of the aforementioned hollow cylinders are connected to the driver devices realized there.

The driver devices are preferably formed as teeth comprising a plurality of teeth extending in the axial direction and arranged distributedly on each periphery. In this case, one or more supporting elements may be incorporated into the teeth, which are used for absorbing the actuating force applied to the clutch device in the axial direction for actuation of the respective clutch device. Thus, for example, the support element may be a gap in the teeth, on which gap the counter plate of the disc pack is supported in the axial direction, or can be supported.

To form a mechanical unit that simplifies assembly processes, the hollow annular cylinder of the disc carrier comprises at least one end face connecting member radially connecting the two hollow cylinders of the hollow annular cylinder to each other.

In order to transmit torque from the rotationally driven component to the disk carrier or vice versa, the disk carrier transmits, on its radial outer surface, the torque from the disk carrier to the component radially connected to the disk carrier. It includes one or more torque transmission members for. In this way, torque can be transmitted from the disk carrier to the rotor carrier of the hybrid module which radially surrounds the disk carrier and vice versa.

The torque transmitting member can likewise be a tooth which makes it possible to insert the disc carrier or the entire insertion module axially into the rotor carrier.

The disk carrier may be formed as a single member or as a multi-member, in particular as a two-member, the disk carrier comprising an inner member and an outer member, the mechanical connection of the inner and outer members being an inner hollow cylinder and an outer hollow cylinder. It is formed at a radial position between the radial positions of the cylinder. Thus, in particular, the end face connecting member can be divided into two, the outer portion of the end face connecting member being disposed on or formed by the outer member of the disk carrier, and the inner portion of the end face connecting member. is disposed on or formed by the inner member of the disc carrier, and a mechanical connection is formed between an inner portion of the end face member and an outer portion of the end face member. The mechanical connection can be formed via a number of screw or riveted connections realized on the periphery of the connection area, or via clinch or welded connections. The multi-parts of the disk carrier allow manufacturing of the disk carrier using relatively simpler and more cost effective manufacturing methods. In addition, the multi-member nature of the disk carrier also opens up the possibility of a different assembly sequence of the disk carrier into the rotor carrier of the hybrid module, since first one of the elements of the inner and outer members is placed in or on the rotor carrier. and, if desired, the clutch devices can be inserted into the space enclosed by the rotor of the electric machine of the hybrid module, and only then, on each other side, optionally previously equipped with a disk pack of additional clutch devices. This is because the member can be inserted.

In particular, in this case, each through-opening has to be substantially aligned with the axial profile of the first hollow cylinder on the inside of the disk carrier. Preferably, the through openings are arranged exactly on a diameter centered on a common axis of rotation, which diameter also coincides with the diameter of the first hollow cylinder inside the disc carrier. This allows the use of a tool that is structurally simple to form, namely a pin which can be inserted through the through openings aligned with one another, in the axial direction, at each angular position where the through openings are aligned with one another. (pin). In this case, the through-holes and the pin are rotationally fixed accommodation of the disks of the disk pack of one of the clutch devices in the state of axially inserting the pin into the through-holes and when inserting the disk carrier into the rotor carrier. For this, it is formed in such a way that collision between the pin and the tooth disposed on the inner surface of the disk carrier does not occur.

In addition, for ease of assembly, the hollow annular cylinder of the disc carrier includes at least one end face connecting member for connecting the two hollow cylinders of the hollow annular cylinder to each other in a radial direction, substantially axially of the disc carrier of the insertion module. At the transition from the directionally extending hollow cylinder to the end face connection member, the disk carrier is configured to radially displace the radially projecting locking member during axial displacement of the disk carrier into the rotor carrier, said locking member. It includes a section with an oblique profile in at least some areas for the purpose of realizing a wedge action for .

The axial insertion of the disk carrier of the insertion module into the rotor carrier is thus facilitated, since the locking member no longer blocks the displacement movement of the disk carrier in the axial direction based on the radial displacement of the locking member. A region comprising an oblique profile can be formed via a conical segment between each hollow cylinder and the end face connecting member. In an alternative embodiment, the region comprising the oblique profile is formed convexly curved on the outer surface, similar to a hollow spherical segment. Thus, the convexly curved region includes points where the applied tangents include the aforementioned oblique profile.

For axial fixation between the disk carrier and the rotor carrier, the disk carrier preferably comprises, on one of its radial limiting sides, a shaped element on which the rotor carrier and A locking member, in particular a spring ring, disposed between the disk carriers can be seated in the axial direction. Accordingly, relative axial movement between the rotor carrier and the disc carrier in either direction is prevented.

In a preferred constructional embodiment, the shape member is formed through a cavity into which a locking member, in particular a spring ring arranged between the rotor carrier and the disk carrier, can be radially engaged. The cavity, which may also be referred to as a groove or a penetration, allows a locking member or spring ring to be axially supported on one side on the cavity and thus block relative axial movement between the rotor carrier and the disk carrier. there is. In particular, in this case, engagement of the locking member into the first hollow cylinder of the disk carrier forming its radially inward limit is performed.

Another aspect of the present invention is a hybrid module for a vehicle for connecting an internal combustion engine and a transmission, the hybrid module comprising an insert module according to the present invention and an electric machine in which a rotor thereof is connected in a rotationally fixed manner to a rotor carrier. do. The rotor carrier is coupled to the insertion module in a rotationally fixed manner, whereby the torque applied by the rotor of the electric machine can be transmitted to the insertion module. A radially protruding locking member, in particular a spring ring, is arranged in or on the rotor carrier and extends in a radial direction from said rotor carrier in some areas into the disc carrier. In this way, an axial fixation of the disc carrier or insertion module on the rotor carrier is ensured.

For the operation of clutch devices disposed parallel to each other in the axial direction, an axially acting actuating member mechanically connected to the compression plate of one clutch device of the two clutch devices is a disc pack of an axially adjacent clutch device. through the disk pack to realize axial movement transfer. The clutch device comprising the disk pack is assigned an actuating system which can be positioned either inside or outside the space enclosed by the disk carrier in radial and axial directions. Correspondingly, the actuation system mechanically coupled to the actuating member penetrating the disc pack in the axial direction can also be located inside or outside the space enclosed by the disc carrier in the radial and axial directions. The operating systems described above can be assigned to the two part clutch devices of a double clutch device.

In this case, the driver devices, which are preferably provided as teeth, are arranged at equal radially spaced distances up to a common rotational axis for the transmission of torque to the two clutch devices which are axially arranged next to each other, but axially adjacent clutches. In one of the devices, the disks that do not interact with the driver devices of the disk carrier have a radial extension smaller than the radial extension of the adjacent clutch device, because the radial end faces of said disks This is because between the wheel and the driver device, an actuating member acting in the axial direction passes through the disk pack. The actuation system for the split clutch can be arranged in the axial direction on the faces of the disc carrier located opposite to the two actuation systems mentioned, wherein the actuating member assigned to the actuation system is axially arranged in the hollow of the disc carrier. The end face of the annular cylinder passes through the connecting member.

The rotor carrier is preferably formed, in relation to its shape, at least in some areas complementary to the outer shape of the disk carrier, so that the rotor carrier forms a recess in the form of a hollow cylinder and into this recess. The insert module according to the invention can be inserted and preferably form-fitted with the rotor carrier, for example by means of outer toothings which interact in a rotationally fixed manner with the inner toothings of the rotor carrier. can be connected in this way. In other words, the rotor carrier radially surrounds the disk carrier at least in some areas. With separately manufacturable insert modules, a modular assembly of the hybrid module can be performed.

A locking element, in particular a spring ring, can be arranged between the disc carrier and the rotor carrier in a radially preloaded state. This ensures a positive radial engagement of the locking member into the disc carrier, whereby unintentional separation of this axial fixation is ruled out.

Equally, the present invention relates to a powertrain for a vehicle comprising an internal combustion engine, a hybrid module according to the present invention, and a transmission, wherein the hybrid module is mechanically connected to the internal combustion engine and the transmission through clutch devices of the module inserted into the hybrid module. can be, or are connected.

According to the invention, the locking element, in particular the spring ring, also engages in a form-fitting manner with the rotor carrier and the disc carrier in the radial direction.

In this case, the steps for realizing the respective rotationally fixed connection do not necessarily have to be executed in the stated order. Prior to the realization of a rotationally fixed mechanical connection between the output shaft and one of the clutch devices of the insertion module, the housing member of the hybrid module to which the insertion module is to be provided can be rotationally mounted on the output shaft.

An actuator or operating system for operating one of the clutch devices, in particular a split clutch, may be disposed in or on a wall of the housing member. The rotor carrier on which the rotor of the electric machine is arranged in a rotationally fixed manner relative to the rotor carrier can be arranged on one section of the housing element, whereby the rotor carrier is rotationally movable relative to the housing element .

During the assembly process, the insertion module is inserted axially into the rotor carrier together with the detachable clutch housed therein and a further clutch device, for example a starting clutch. An intermediate shaft coupled with the insertion module or one of the clutch devices, for example coupled with the input side of the split clutch, is rotationally coupled with the output shaft of the internal combustion engine.

In a preferred embodiment of the method according to the invention for assembling a powertrain, an inner disc carrier or an outer disc carrier for the purpose of applying a force with a radial component for a radial displacement of a radially protruding locking element, in particular a spring ring. A tool is axially inserted through the axially extending through openings in the disk carrier. Through the radial displacement of the locking member, a place is provided in the radial direction for axially inserting the disc carrier or insertion module into the rotor carrier. During insertion of the disk carrier into the rotor carrier, the disk carrier radially displaces the locking member, so that the locking member cannot develop a locking action in the axial direction.

Based on the radial displacement, the locking element, preferably formed as a spring ring, is automatically radial if it overlaps in the radial direction by a cavity or groove in the disk carrier, in other words if it is inserted into the cavity or groove in the radial direction. is moved back to This is additionally made possible by the fact that the tool previously inserted into the through-openings is pulled out of the through-openings.

It is shown that two hollow cylinders 95 are seated on their inner surfaces 96 and are axially supported there.

In Fig. 6, the disc spring 86 is invariably axially supported only on the stepped member 97, but the disc spring 76 is supported on a support ring 98, which in turn is axially supported. An alternative embodiment is shown supported on a stepped member 97 with .

The embodiment according to FIG. 7 is advantageous in that instead of the support ring 98 a snap ring 99 is arranged, on which the radially outer rim 200 of the disc spring 76 is axially supported. , which is distinguished from the embodiment shown in FIG. 6 .

8 and 9 show portions cut out of the hybrid module according to the present invention, respectively, and FIG. 9 shows a more severely enlarged view of the related area.

The recesses 303 are inserted into the end face 304 of the rotor carrier 30 in the embodiment shown here. In this way, in a simple and space saving manner, torque is transmitted between the rotor carrier 30 and the disk carrier 90 or the insertion module 40 formed with the disk carrier. For the purpose of fixing the axial position of the disc carrier 90 relative to the rotor carrier 30, a retaining element 305 is arranged on the radial inner surface of the rotor carrier 30, which retaining element is radially inserted into the rotor carrier 30 to block axial displacement of the disk carrier 90 and thus the insertion module 40 through axial seating on the disk carrier 90 .

In the embodiment shown here, the gripping member is not the only member blocking axial displacement, but also on the first hollow cylinder 93 of the disk carrier 90, the radial inner surface of the first hollow cylinder and the rotor carrier Between 30 there is an additional element for blocking the translational degree of freedom of the disc carrier 90 , namely here a spring ring 306 arranged in a groove 309 in the rotor carrier 30 .

A dowel pin 307 is provided as an additional structural member for form-fitting transmission of torque between the rotor carrier 30 and the disk carrier 90, which dowel pin is the end face of the disk carrier 90.

For the purpose of realizing a structurally simple operation of the illustrated split clutch 50, one or more through openings 308, preferably a plurality of such types, are provided in the rotor carrier 30 and also in the end face connecting member 110. through-openings 308 are provided, through which the clutch actuating member 310 passes for application of an actuating force to the disks of the detachable clutch 50 .

10 shows another cut-out of the hybrid module according to the invention, namely here in particular a split clutch 50 , which likewise is arranged on the inside of the disc carrier 90 . Here, it can be seen that the disk carrier 90 rests on the rotor carrier 30 with its radially inner limit. In order to fix the axial position of the disk carrier 90 or the insertion module 40 with the disk carrier relative to the rotor carrier 30, a locking element in the form of a spring ring 306 shown here is provided on the rotor carrier. (30) and the disk carrier (90).

In the illustrated position of the spring ring, where the spring ring 306 has a larger diameter than the rotor carrier 30, the spring ring 306 remains free and extends within the outline shown in dashed lines. After assembly of the spring ring 306 on the rotor carrier 30 and before axially inserting the disk carrier 90 or the insertion module 40 with the disk carrier into the rotor carrier 30, the spring ring 306 represents an axial block thus preventing the insertion process.

To enable insertion, axially extending through openings 400 are formed in the two inner disk carriers 74 , 84 of the first partial clutch device 70 and the second partial clutch device 80 . do. A through opening 400 of this type is also formed in the outer disc carrier 54 of the split clutch 50 . The through openings 400 are arranged in such a way that they can be aligned with each other in the axial direction, as shown in FIG. 10 . This allows axial insertion of the tool 401 into the through openings 400 . The radially protruding spring ring 306 can be displaced into the rotor carrier 30 in order to enable unhindered insertion of the disc carrier 90 into the rotor carrier 30 by means of a tool. A plurality of uniformly distributed through openings 400 are preferably provided in the inner disc carriers or the outer disc carrier, which allow simultaneous axial engagement of a plurality of tools 401 . Another auxiliary means when inserting the disk carrier 90 into the rotor carrier 30 is caused by a section comprising an oblique profile 403 on the disk carrier 90 at least in some areas. The section 403 is disposed between the inner first hollow cylinder 93 of the disk carrier 90 and the end face connecting member 110 extending substantially perpendicular thereto. The oblique area on the disc carrier 90 or the rounding provided thereon causes a wedging action on the radially protruding spring ring 306 when inserting the disc carrier 90 into the rotor carrier, thereby During the insertion movement of the disk carrier 90 into the rotor carrier 30, the disk carrier 90 comes into close contact with each other in the axial direction.
