They connect three main components to form one operable unit. The electric motor enables electric running, increased power for the combustion engine mode, and regeneration. The separate clutch and its operating system provide for the connection or disconnection of the combustion engine. If the hybrid module is combined with a double clutch in such a way that the hybrid module is located between the combustion engine and the transmission in the torque transmission direction, the combustion engine, the hybrid module, the double clutch including its operating systems, and the transmission in the vehicle are successively 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 the assembly or make the assembly difficult.

From DE 10 2009 059 944 A1 a hybrid module is known which includes a separate clutch inside the rotor of an electric machine. The separate clutches of the double clutch device are arranged next to the rotor of the electric machine and thus also next to the separate clutch in a axially offset manner.

Preferred embodiments of the insertion module herein are specified in the dependent claims 2 to 5. Preferred embodiments of the hybrid module of the present application are specified in the dependent claims. Preferred embodiments of the method herein for assembling a powertrain are specified in the dependent claims 10.

The features of the claims can be combined in their respective technically appropriate types and manners, to which the features in the description and drawings in the following description, including supplementary embodiments of the invention, can also be added. have. The axial and radial direction indications relate to the common axis of rotation of the device assemblies described above. Thus, the axial direction is oriented perpendicular to the friction surfaces of the disks.

The present invention relates to an insertion module for placement in a hybrid module of a motor vehicle, the insertion module comprising a disk carrier which is substantially rotationally symmetrical, two or more clutch devices, in particular one separate clutch and one or more starting clutches, The clutch devices each comprise one or more disc packs, in which each one or more discs is a driver device of the disc carrier, in particular a tooththing and a torque-resistant manner. ). The disc carrier bears the form of a hollow annular cylinder consisting essentially of two hollow cylinders arranged in rotational symmetry. Further, the driver devices are arranged in a space portion radially defined by the disk carrier on one or more of the sides of the hollow annular cylinder which are spaced radially apart from each other.

The insertion module of the present disclosure includes inner disk carriers and outer disk carriers connected to the disk packs of the clutch devices, by which each clutch device is provided with one or more outputs of the hybrid module to which the insertion module is to be provided. Can be connected to the side in a rotationally fixed manner. Each inner disk carrier or outer disk carrier includes one or more through openings extending axially, thereby projecting radially in a rotor carrier radially seated on the disk carrier in the assembled state of the insertion module. The through opening of the inner disk carriers or the outer disk carriers in the axial direction by the tool for the purpose of applying a force with a radial component for the radial displacement of the locking element, in particular the spring ring. Can pass through them.

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

In particular, in the assembled state of the insertion module, in or on the rotor carrier the locking member starts at the rotor carrier and extends radially into the disk carrier, in particular into the radially inner first hollow cylinder 93 of the disk carrier. do.

The inner disk carriers or the outer disk carriers are rotatably arranged about a common axis of rotation, whereby they can be arranged in a line aligned with each other in the axial direction at a predetermined angular position, so that the tool at the angular position It may pass through the through openings.

In addition to the through openings for radially displacing the locking member and the function of the tool inserted therein, the through openings and the tool are additionally in the common disk carrier through the axial insertion of the clutch devices as a whole as a result. In order to facilitate the assembly of the clutch devices in the system, the inner disk carriers or the outer disk carriers and the disks arranged on the inner or outer disk carriers while also being the disks of the disk packs of the clutch devices are also mutually mutual. It is used to position the liver relatively accurately.

Clutch devices may be formed as wet clutches. In this case, the separate clutch device is in particular connected with the input side of the hybrid module. Preferably, in addition to the separate clutch, two partial clutch devices of the double clutch device are provided, the disk packs of these partial clutch devices being connected to the output side of the hybrid module.

In this case, the torque resistant application of the disk of the disk pack to the driver device can allow for axial displacement. For this purpose, the driver device is preferably formed as plug-in toothing. In this case, the hollow annular cylinder is a body which forms an outer surface on which its inner hollow cylinder is radially opposed to the inner surface of the outer hollow cylinder.

Thus, as a subassembly or subassembly group, an insertion module is provided which can be inspected from the outside of the hybrid module, which is also referred to as a triple clutch when accommodating three clutch devices. The advantage of such an insertion module is that it can be carried out in a reliable manner, in particular that almost all the assembly steps and measurement procedures necessary for the manufacture of the insertion module can be carried out on the outside of the rotor of the electric machine of the hybrid module for which the insertion module is provided. Based on the fact that all geometric ratios between the clutch arrangements and relative to the disc carrier can be set to their respective intended actual dimensions, the dimensional accuracy in the assembled state is high or the assembly tolerance is small.

Also, in doing so, the setting procedures in the clutch devices are each performed relatively simpler and more accurately. In addition, the insertion module according to the invention makes it possible to manufacture insertion modules for several hybrid modules or rotor carriers, only the contour of the insertion module being so-called "which can be integrated into the rotor carrier regardless of location and time. In order to provide one unit as "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 radially offset manner from each other, and the driver devices have two inner surfaces of the two hollow cylinders of the hollow annular cylinder for connection with one or more disks of one disc pack. On the two inner surfaces facing each other and radially spaced apart from each other, in a space defined radially by the disc carrier. In other words, the driver devices are arranged in a hollow annular cylinder chamber which is radially defined by the disk carrier on inner surfaces located opposite one another in the radial direction, wherein the disk packs are connected in a rotationally fixed manner. As a result, the disk packs are connected to opposite inner surfaces.

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

Despite the arrangement of the three disc packs, the insertion module according to the invention offers the advantage of simple handling, especially during assembly on the assembly line and during insertion into the rotor carrier of the hybrid module to be manufactured, whereby the assembly is simplified Can be performed in a manner and reliably manually, or can be automated.

In particular the disk packs of the first partial clutch device and the second partial clutch device of the double clutch device are arranged on the inner surface of the outer hollow cylinder, and the disk pack of the separate clutch is arranged on the outer surface of the inner hollow cylinder. The disks of the disk packs at these faces of the hollow cylinders described above are connected to the driver devices realized there.

The driver devices are preferably formed as teeth, which are arranged on each circumference and comprise a plurality of teeth extending in the axial direction. In this case, one or more supporting elements can be incorporated in the tooth, which are used to absorb the operating force applied to the clutch device in the axial direction for the operation of each clutch device. Thus, for example, the support element may be a gap in the tooth, on which the opposing plate of the disc pack may be supported or supported axially.

To form a mechanical unit that simplifies the assembly processes, the hollow annular cylinder of the disc carrier comprises one or more end face connecting members connecting the two hollow cylinders of the hollow annular cylinder to each other in the radial direction.

In order to transfer torque from the rotationally driven component to the disk carrier, or vice versa, the disk carrier transfers the torque from the disk carrier to the component radially connected to the disk carrier, on its radial outer surface. One or more torque transmission members for the purpose of the invention. In this way, torque can be transferred 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 axially insert the disc carrier or the entire insertion module into the rotor carrier.

The disc carrier can be formed in a single member or in a multi-member form, in particular in a two-member form, wherein the disc carrier comprises an inner member and an outer member, and the mechanical connection of the inner and outer members is an inner hollow cylinder and an outer hollow 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 part of the end face connecting member being disposed on or formed by the outer member of the disc carrier, and the inner part of the end face connecting member Is disposed on or formed by the inner member of the disc carrier, and the mechanical connecting portion is formed between the inner portion of the end face member and the outer portion of the end face connecting member. The mechanical connection can be formed through a plurality of screw or rivet joints realized on the periphery of the connection region, or via clinch or weld joints. Mutualle parts of the disc carrier enable the manufacture of the disc carrier using relatively simpler and more cost effective manufacturing methods. In addition, the multiple absence of the disc carrier also discloses the possibility of another assembly order of the disc carrier into the rotor carrier of the hybrid module, since one of the members of the inner member and the outer member is first placed in or on the rotor carrier. If desired, the clutch devices can be inserted into the space enclosed by the rotor of the electric machine of the hybrid module, after which the other side, if any, is provided with a disc pack of an additional clutch device in advance. This is because the member can be inserted.

In particular, in this case, each through opening must be substantially aligned with the axial profile of the first hollow cylinder inside the disc carrier. The through openings are preferably arranged on a diameter about 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 simply structurally formed, that is to say a pin that can be inserted through the through openings aligned in line with one another in the axial direction at each angular position where the through openings are arranged in line with each other. Enable the use of (pin). In this case, the through openings and the pin are rotatably receiving the disks of the disc pack of the clutch pack of one of the clutch devices, with the pin inserted axially into the through openings and when the disc carrier is inserted into the rotor carrier. And the teeth disposed on the inner surface of the disc carrier for the purpose of preventing collision of the pins with each other.

In addition, for ease of assembly, the hollow annular cylinder of the disc carrier comprises at least one end face connecting member which radially connects the two hollow cylinders of the hollow annular cylinder with each other and is substantially axle of the disc carrier of the insertion module. The disc carrier at the transition from the hollow cylinder extending in the direction to the end face connecting member is adapted to radially displace the radially projecting locking member during the axial displacement of the disc carrier into the rotor carrier. And a section with an oblique profile in at least some area for the purpose of realizing a wedge action for.

The axial insertion of the disc carrier of the insertion module into the rotor carrier is thus facilitated because the locking member no longer blocks displacement of the disc carrier in the axial direction based on the radial displacement of the locking member. The region comprising the oblique profile can be formed through the 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 the hollow spherical segment. Thus, the convexly curved region includes points where applied tangents include the above-described oblique profile.

For axial fixation between the disc carrier and the rotor carrier, preferably, the disc carrier comprises a shaped element on one of its radially limiting sides, 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. Thus, axial relative movement between the rotor carrier and the disc carrier in either direction is prevented.

In a preferred structural embodiment, the shaped member is formed through a cavity, into which the locking member, in particular a spring ring, disposed between the rotor carrier and the disk carrier can be radially engaged. The cavity, which may also be referred to as a groove or penetration, may allow the locking member or spring ring to be supported on the cavity at one side in the axial direction and thus block axial relative movement between the rotor carrier and the disc carrier. have. In particular, in this case, the engagement of the locking member into the first hollow cylinder of the disc carrier forming its radially inner restriction is performed.

Another aspect of the invention is an automotive hybrid module for connecting an internal combustion engine and a transmission, the hybrid module comprising an insertion module according to the invention and an electric machine in which its rotor is connected to the rotor carrier in a rotationally fixed manner. 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. The radially protruding locking member, in particular the spring ring, is disposed in or on the rotor carrier and extends from the rotor carrier in the radial direction into the disk carrier in some region. In this way, axial fixation of the disc carrier or the insertion module on the rotor carrier is ensured.

For operation of clutch devices arranged side by side in the axial direction, the axially actuating member, which is mechanically connected to the pressing plate of one clutch device of the two clutch devices, is a disc pack of the clutch device adjacent in the axial direction. It can pass through the disk pack to realize axial movement transfer through it. The clutch device comprising the disc pack is assigned an operating system which can be located inside or outside the space portion enclosed by the disc carrier in the radial and axial directions. Correspondingly, the actuation system mechanically coupled with the actuating member penetrating the disc pack in the axial direction can also be located inside or outside the space portion enclosed by the disc carrier in the radial and axial directions. The aforementioned operating systems can be assigned to two partial clutch devices of the double clutch device.

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

The rotor carrier is preferably formed complementary to the outer shape of the disc carrier in at least some area with respect to its shape, whereby the rotor carrier forms a recess in the form of a hollow cylinder and into this recess. The insertion module according to the invention can be inserted, and is preferably shape-coupled with the rotor carrier using, for example, an outer toothing which interacts in a rotationally fixed manner with the inner tooth of the rotor carrier. Can be connected in a manner. In other words, the rotor carrier surrounds the disk carrier radially in at least some region. Modular assembly of the hybrid module can be carried out via an insert module which can be manufactured separately.

The locking member, in particular a spring ring, may be arranged between the disc carrier and the rotor carrier in the radial preload state. This ensures a secure radial engagement of the locking member into the disc carrier, thereby eliminating the unintended separation of this axial fixation.

Equally, the present invention relates to an automotive powertrain comprising an internal combustion engine, a hybrid module according to the invention and a transmission, the hybrid module being mechanically connected to the internal combustion engine and the transmission via clutch devices of an insertion module in the hybrid module. Can be connected or connected.

In addition to this, according to the invention, there is provided a method for assembling a powertrain according to the invention, in which case an insertion module according to the invention is provided, a rotor carrier of a hybrid module to be produced is provided, and an internal combustion The output shaft of the engine is provided, the disc carrier of the insertion module is inserted into the radially enclosed space by the rotor carrier, the rotationally fixed mechanical connection between the output shaft and one of the clutch devices of the insertion module, and the disc carrier A rotationally fixed mechanical connection between the rotor and the rotor carrier is realized. According to the invention, the locking member, in particular the spring ring, also engages in a radially engaging manner with the rotor carrier and the disk carrier in the radial direction.

In this case, the steps of realizing each of the rotationally fixed connections need not necessarily be performed in the order mentioned. Before realization of the 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 may be rotatably mounted on the output shaft.

One of the clutch devices, in particular an actuator or actuation system for actuating the separate clutch, may be arranged in or on the 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 member, whereby the rotor carrier becomes rotatable relative to the housing member. .

During the assembly process, the insertion module is inserted axially into the rotor carrier, with a separate clutch contained therein, and an additional clutch device, for example a starting clutch. An intermediate shaft, which is coupled with one of the insertion module or clutch devices, for example with the input side of the separate clutch, is coupled in a rotationally fixed manner with the output shaft of the internal combustion engine.

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

On the basis of the radial displacement, the locking member, preferably formed as a spring ring, is automatically radial if it is overlapped by a cavity or groove in the disc carrier in the radial direction, that is to say inserted into the cavity or groove in the radial direction Is moved back to. This is also possible through the fact that the tool previously inserted into the through openings is pulled out of the through openings.

Pressure members 85 and 86 are assigned to each of clutch devices 70 and 80 disposed adjacent in the axial direction. The pressure member 75 of the first clutch device 70 is supported directly or directly in the axial direction on the disc pack 71 of the first partial clutch device 70.

The pressure member 85 of the second partial clutch device 80 is indirectly supported on the disk pack 81 of the second partial clutch device 80, that is to say here the disk of the disk pack of the first partial clutch device 70. It is supported by an actuating member 83 which acts in the axial direction while passing through them.

In addition, one disc spring 76, 86 is assigned to each of the two partial clutch devices 70, 80. These disk springs 76, 86 are supported on the inner surface 96 of the second hollow cylinder 95 of the disk carrier 90 by its respective radial outer rim 200. For this purpose, the disc carrier 90 comprises stepped members 97 in this regard.

The radially inner edge 201 of each disk spring 76, 86 acts on the respective pressure member 75, 85 in the axial direction. Each pressure member 75, 85 is mechanically connected to the respective operating system 72, 82 of the two-part clutch devices 70, 80 in the axial direction.

To pass). In this way, the disks of the disc packs 71, 81 are in close contact with each other, and torque can be transmitted by the respective partial clutch devices 70, 80. When the partial clutch devices 70, 80 are to be opened again, the operation of each operating system 72, 82 is terminated. Each disk spring 76, 86 now causes an axial return movement of the respective pressure member 75, 85 such that the disks of the disk packs 71, 81 can be separated from each other.

In FIG. 2, the disk carrier 90 is shown as a single member component. Here, in particular, the driver device 100 which is also arranged on the outer surface 94 of the first hollow cylinder 93 and on the inner surface 96 of the second hollow cylinder 95 can also be confirmed. The two hollow cylinders 93, 95b are mechanically connected via a connecting member 110 at the end face.

However, the disc carrier 90 may also be formed as a two member type component as can be seen in FIGS. 3 and 4. In the case of a two-member part, as shown in FIG. 3, a mechanical connection 132 between the inner member 130 and the outer member 131, separating the two separate members adjacent to the separate clutch 50. joints are provided. The detachable joint or mechanical connection 132 may be, for example, a welded joint.

In the three figures, the axial opening 87 in the actuating member 83 acting in the axial direction of the second partial clutch device 80 is radially larger than the outer diameter of the two disc springs 76, 86. It can be seen that it has an extension or larger diameter. This enables the possibility of later insertion of the disc springs 76, 86 into the disc carrier 90 with the actuating member 83 acting in the axial direction already assembled.

In FIG. 5, not only the disk spring 76 of the first partial clutch device but also the disk spring 86 of the second partial clutch device 80 are also formed on the stepped member 97 of the disk carrier 90, respectively. The point is shown seated on its inner surface 96 of the hollow cylinder 95 and supported there axially.

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

In the embodiment according to FIG. 7, a snap ring 99 is disposed instead of the support ring 98, on which the radially outer rim 200 of the disc spring 76 is supported in the axial direction. , It is distinguished from the embodiment shown in FIG.

Here, in the axial end region 300 of the disc carrier 90 the disc carrier comprises shaped members 301, ie so-called fingers, which protrude radially outward from its second hollow cylinder 95. It can be seen that. The shape members 301 protruding outward in the radial direction penetrate the rotor carrier 30 in the radial direction, that is to say arranged in the rotor carrier 30 for this purpose and in particular retaining the form of slots. Penetrates the field 303. The recesses 303 are inserted into the end face 304 of the rotor carrier 30 in the embodiment shown here. In this manner, in a simple yet saving mounting space, torque is transmitted between the rotor carrier 30 and the disc carrier 90 or the insertion module 40 formed with the disc carrier. For the purpose of fixing the axial position of the disk carrier 90 relative to the rotor carrier 30, a holding element 305 (retaining element) is disposed on the radially inner surface of the rotor carrier 30. Is inserted radially into the rotor carrier 30 to block axial displacement of the disc carrier 90 and thus the insertion module 40 through axial seating on the disc carrier 90.

In the embodiment shown here, the gripping member is not the only member that blocks the axial displacement, but also on the first hollow cylinder 93 of the disc carrier 90, the radially inner surface of the first hollow cylinder and the rotor carrier. Between the 30 an additional member is arranged for blocking the translational degrees of freedom of the disc carrier 90, ie a spring ring 306 disposed in the groove 309 in the rotor carrier 30.

Dowel pins are provided as additional structural members for the formally coupled transmission of torque between the rotor carrier 30 and the disk carrier 90, which dowel pins are provided at the end faces of the disk carrier 90. It fits in the connecting member 110 and in the rotor carrier 30. For the purpose of realizing the structurally simple operation of the illustrated detachable clutch 50, one or more through openings 308, preferably a plurality of said types, are also present in the rotor carrier 30 and in the end face connecting member 110. Through openings 308 are provided through which the clutch actuating member 310 passes for application of the actuation force to the disks of the separate clutch 50.

In Fig. 10 another cut out part of the hybrid module according to the invention is shown here, in particular here a separate clutch 50, which is likewise arranged inside the disk carrier 90. Here, it can be seen that the disc carrier 90 rests on the rotor carrier 30 with its radially inner limit. In order to fix the axial position of the disc carrier 90 or the insertion module 40 with the disc carrier relative to the rotor carrier 30, the locking member here is in the form of a spring ring 306 shown in the rotor carrier. It is disposed between 30 and the disc 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 is in an untensioned state and extends to within the outline shown by the broken line. After assembly of the spring ring 306 on the rotor carrier 30 and before axial insertion of the disc carrier 90 or the insertion module 40 with the disc carrier into the rotor carrier 30, the spring ring 306 represents an axial block that prevents the insertion process accordingly.

Through openings 400 extending in the axial direction are formed in the two inner disk carriers 74, 84 of the first partial clutch device 70 and the second partial clutch device 80 to enable insertion. do. This type of through opening 400 is also formed in the outer disk carrier 54 of the detachable clutch 50. The through openings 400 are arranged in such a way that they can be aligned with one another in the axial direction, as shown in FIG. 10. This allows for axial insertion of the tool 401 into the through openings 400. By means of a tool, the radially projecting spring ring 306 can be displaced into the rotor carrier 30 in order to enable uninterrupted insertion of the disk carrier 90 into the rotor carrier 30. Preferably, a plurality of through openings 400 are provided that are uniformly distributed within the inner disk carriers or the outer disk carrier, which enable simultaneous axial engagement of the plurality of tools 401. Another auxiliary means when inserting the disc carrier 90 into the rotor carrier 30 is caused through a section comprising an oblique profile 403 in at least some area on the disc carrier 90. The section 403 is disposed between the first hollow cylinder 93 on the inside of the disc carrier 90 and the end face connecting member 110 extending substantially perpendicularly thereto. The beveled area or the rounding portion provided thereon on the disc carrier 90 causes a wedge action on the radially protruding spring ring 306 when inserting the disc carrier 90 into the rotor carrier, whereby the spring ring Is closely spaced inwardly in the axial direction during the insertion movement of the disc carrier 90 into the rotor carrier 30.
