Definitions
- the invention relates to an electric drive unit, in particular a hybrid module for a motor vehicle for coupling an internal combustion engine, and a drive arrangement for a motor vehicle with an internal combustion engine and an electrical drive unit according to the invention.
- Electrical drive units and in particular hybrid modules for motor vehicles or the drive train of a motor vehicle are known from the prior art, which comprise an electrical machine and a coupling device in a torque transmission path between an internal combustion engine and a gear unit.
- the electric machine enables electric driving, driving in a boost mode and recuperation when operating a motor vehicle equipped with the hybrid module. It is known to provide a disconnect clutch and a torque transmission device, the torque transmission device e.g. can be a clutch, a double clutch device, a torque converter or a continuously variable transmission.
- the torque transmission device e.g. can be a clutch, a double clutch device, a torque converter or a continuously variable transmission.
- An actuation system of the disconnect clutch ensures that the internal combustion engine is coupled or uncoupled.
- the torque is always conducted via the torque transmission device.
- a clutch or double clutch device is usually preferred as the torque transmission device.
- all components of the electric drive unit can be designed and arranged very compact. It is very helpful here if as many components of the electric drive unit as possible can be accommodated in a common housing without space-consuming partitions between the components.
- the coupling device slips, heat is generated. So that the friction surfaces do not overheat, which can lead to so-called fading, ie excessive wear of the friction linings and thermally caused component deformations, the friction energy introduced into the clutch device is temporarily stored by heating the material in the clutch plates. The coupling device then releases heat to the surrounding components and to the air surrounding them. The friction surfaces of the clutch rubbing against each other lead to their wear.
- the material removal which is associated with the wear of the clutch linings that occurs over the service life of the clutch, leads to material, mostly referred to as clutch dust or simply as dirt or dirt particles, escaping from the clutch. With electric drive machines, care must therefore be taken not only to protect the electric machine from the heat of the clutch, but also from the dirt of the clutch.
- the unpublished German patent application with the official file number 102017125845.0 describes a hybrid module for a drive train of a motor vehicle, comprising an electrical machine with a rotor arranged on a rotor carrier and a stator, with a disconnect clutch and with a double clutch.
- a carrier plate holds at least the separating clutch on the rotor carrier of the electrical machine.
- the carrier plate is designed such that it after installation with the rest of the hybrid module no longer has a free opening through which air, heat or dirt are transferred from the couplings to the electrical machine.
- the unpublished German patent application with the official file number 102017130349.9 describes an electric drive unit with an electric machine and at least one first coupling device.
- the electrical drive unit Fastened to a rotor or rotor carrier of the electrical machine, the electrical drive unit includes a dirt deflector, so that dirt particles of the coupling device are thrown axially next to the electrical machine.
- a dirt shield can also be present, which is connected to the housing.
- the dirt deflector can have an axial component in its direction of extension, so that it extends both radially and axially and thus obliquely.
- the rotating dirt deflector and / or the non-rotating dirt shield can keep the dirt escaping or thrown off at the front of the electrical machine away from the electrical machine or other sensitive parts and direct it axially to a desired location outside the electrical machine .
- the object of the present invention is to provide an electric drive unit and a drive arrangement equipped therewith, which combine little space requirement and little assembly effort with reliable operation and a long service life.
- axial In the context of the present invention, the terms “axial”, “radial”, “tangential” and “circumferential direction” or “direction of rotation” always refer to the axis of rotation of the electric drive unit.
- the invention relates to an electric drive unit, in particular a hybrid module for a motor vehicle for coupling an internal combustion engine.
- the electrical drive unit comprises an electrical machine for generating a drive torque and at least one clutch device for transmitting the torque provided to at least one output shaft, in particular a transmission input shaft, the electrical drive unit comprising a clutch cover which is connected to a rotor Electrical machine is essentially non-rotatably connected and at least partially realizes a torque transmission path from the electrical machine to the at least one transmission input shaft.
- the at least one coupling device and the electrical machine are arranged on opposite sides of the coupling cover, the coupling cover realizing a gap seal together with a sealing element of the electrical drive unit.
- the gap seal can have a gap which runs in particular at an angle, as a result of which the gap seal is designed as a labyrinth seal. This offers a higher flow resistance than an essentially straight gap.
- the electrical drive unit can be installed very easily.
- the coupling device is attached to the electrical machine by means of the coupling cover.
- the radially outer part of the clutch cover is located axially at a position provided for the gap seal.

- the clutch device 30 has a disconnect clutch 31 and a double clutch device 32, the double clutch device 32 comprising a first partial clutch 33 and a second partial clutch 34.
- the output side of the first partial clutch 33 is connected in a rotationally fixed manner to the first transmission input shaft 70, and the output side of the second partial clutch 34 is connected in a rotationally fixed manner to the second transmission input shaft 71.
- the electrical machine 20 comprises a rotor 21 and a gate 22.
- a clutch cover 40 which is connected to the separating clutch 31 and the rotor 21 of the electrical machine 20 by means of a rotationally fixed connection 23.
- an input element 35 of the double clutch device 32 here configured as a central plate, is connected to the clutch cover 40 in a rotationally fixed manner.

- a torque made available by an internal combustion engine (not shown) can be transmitted to the separating clutch 31 via the output device 3, here configured as an intermediate shaft mechanically coupled to the vibration damper 72.
- a torque made available by the electrical machine 20 can be transmitted via the clutch cover 40 to the input element 35 of the double clutch device 32.
- the electric drive device 1 further comprises a housing 10 with a first housing component 11 and a second housing component 13, the coupling device 30 being arranged in a first housing interior 12 of the first housing component 11, and the electrical machine 20 in a second housing component. Interior 14 of the second housing component 13 is arranged.
- the two housing components 11, 13 are firmly connected to one another via a plurality of connecting points 15 distributed over the circumference by means of connecting screws 16.
- the clutch cover 40 essentially separates the first housing interior 12 from the second housing interior 14 and thus spatially the coupling device 30 from the electrical machine 20, the clutch cover 40 being designed as a largely closed sheet metal part. This ensures that particles released from the separating clutch 31 or one of the partial clutches 33, 34 cannot reach the electrical machine 20 directly.
- the clutch cover 40 has an axial and also a radial extension component, with the axial extension on a radial inside of the clutch cover 43 making it possible to remove particles in the axial direction, in particular away from the electrical machine 20.
- the clutch cover 40 is designed as a component rotating about the axis of rotation 2 and the housing 10 is fixed, there is a relative rotation between these elements during operation of the electric drive unit 1, which is caused by a gap 51 between the clutch cover 40 and the housing 10 is made possible.
- the electrical drive unit 1 comprises a gap seal 50 and a receiving space 60 for receiving particles that have accumulated.
- the gap seal 50 is formed by the clutch cover 40, a sealing element 52 and a sealing web 53.
- the sealing web 53 is designed as a ring and is arranged in the first housing interior 12 on the first housing component 11. In this case, an end region 41 of the clutch cover 40 extends, which essentially corresponds to the end of the clutch end facing away from the electrical machine 20. ckels 20 corresponds radially next to the sealing web 53 in the axial direction.
- the sealing element 52 is designed as a sealing plate and is arranged in the connection point 15 between the two housing components 11, 13, wherein it extends radially inwards and thereby a section of the clutch cover 40 between itself and an outside 42 Gap seal 50 forms. In this section, the contour of the sealing element 52 essentially follows the contour of the outside of the clutch cover 40, so that the gap 51 in this section has an essentially constant thickness or width.
- the receiving space 60 formed in the first housing component 11 is designed as a recess in the side of the first housing component 11 facing the connection point 15, the sealing element 52 thereby limiting the receiving space 60 in the axial direction or closing it off in terms of flow technology.
- the receiving space 60 is connected in terms of flow technology by means of a channel 61 to the gap seal 50 or its gap 51.
- the channel 61 represents the only opening 65 of the receiving space 60.
- the channel 61 is arranged axially between the sealing element 52 and the sealing web 53. It is therefore positioned axially between the end region 41 of the clutch cover 40 which faces axially away from the electrical machine 20 and the electrical machine 20.
- Particles released by the coupling device 30 are thus discharged along the inside 43 of the clutch cover 40 and then flung off by the latter.
- the particles In order to get to the electrical machine 20, the particles would have to flow through an axial gap 51 between the end region 41 of the clutch cover 40 facing away from the electrical machine 20 in the radial direction and the sealing web 53 located on the first housing component 11. The particles would then have to flow radially inwards and follow the gap 51 between the sealing element 52 and the clutch cover 40. In order to get into the sealing gap, the particles would have to overcome the step between the inner contour of the housing 10 and the inner contour of the sealing web 53 in the radial direction towards the inside.
- the entire gap seal 50 is designed in such a way that it greatly impedes or completely prevents the particles from flowing through.
- the particles of the coupling device 30 rotating in the first housing component 11 cause the particles to swirl around so that they are subject to a centrifugal force. A movement of the particles radially inward is thus prevented or made more difficult by rotation of the rotating components of the coupling device 30.
- the air flow in or through the gap 51 is severely restricted by the angular course and the small gap width, so that hardly any particles can be conveyed into the gap 51 and possibly even through the gap 51.
- This gap 51 leads continuously radially inward, so that particles which are accelerated in the tangential direction by the rotation of the clutch cover 40 are again transported radially outward from the gap 51 by the centrifugal force.
- the particles which have further entered the gap 51 thus move radially outward again, at least as a result of centrifugal force, before the gap seal 50 finally passes and pass through the channel 61 into the receiving space 60.
- the receiving space 60 has only exactly one opening 65, so that an air flow from one opening 65 to the next is excluded. sen, whereby the particles in the receiving space 60 could otherwise be whirled up again and transported out of the receiving space 60.
- the second housing interior 14, in which the electrical machine 20 is arranged, is thus kept free of particles of the coupling device 40 by the gap seal 50 and the receiving space 60.
- the electrical drive unit 1 essentially corresponds to the electrical drive unit 1 from FIG. 1, with the difference that the channel 61, which fluidically connects the first housing interior 12 to the receiving space 60, is arranged in the axial direction on the other side of the sealing web 53 .
- the end region 41 of the clutch cover 40 which faces axially away from the electrical machine 20 is thus positioned axially between the channel 61 and the electrical machine 20. It is thus realized that particles specified by the coupling device 30 already fall into the receiving space 60 through the channel 61 and are held there before they enter the gap seal 50.
- FIG. 3 shows a first housing component 11 of an electric drive unit 1 according to the invention.
- FIG. 3 is shown here in addition to FIG. 1 and shows a corresponding section of the embodiment shown in FIG. 1.
- a plurality of receiving spaces 60 can be provided.
- Each receiving space 60 is connected to the first housing interior 12 by means of a channel 61.
- the channels 61 have a tangential component in their respective extension. The shape and orientation of the channels 61 are thus adapted to the direction of rotation of the coupling device 30 and to the direction of flight of the particles, so that the areas where the particles emerge from the channel 61 into the receiving space 60 are seen behind the openings in the direction of rotation 65 lie through which the particles penetrate into the channel 61.

- the end region 41 of the clutch cover 40 is arranged here, as in FIG. 5, in the axial direction between the axially delimiting sides of the channel 61, the first housing component 11 being a side facing away from the electrical machine 20 and the second housing component 13 forms a limiting side facing the electrical machine 20.
- the part formed by the first housing component 11 and delimiting the channel 61 extends further in the radial direction than the part formed by the second housing component 11 and delimiting the channel 61.
- FIG 9 shows an enlarged section of an electrical drive unit 1 according to the invention in the area of the gap seal 50 or the receiving space 60 according to a sixth embodiment.
- FIG. 9 is essentially a section of the embodiments of an electric drive unit 1 according to the invention shown in FIGS. 1 or 2.
- FIG. 9 differs from these embodiments by the configuration of the gap seal 50 or the receiving space 60.
- FIG. 9 is similar to the design of the gap seal 50 or the receiving space 60 according to FIG. 8. The only difference is the design of the channel 61 and the gap seal 50.
- the side of the channel 61 which delimits the channel 61 and faces away from the electrical machine 20 is shown in FIG 9 not axially further away from the electrical machine 20 than the end region 41 of the clutch cover 40, but essentially in the axial direction at the identical axial position as the end region 41 of the clutch cover 40. Accordingly, the channel 61 is here in the axial direction - Tungth designed narrower than the channel 61 of Figure 8.
- the gap seal 50 is formed by the end region 41 of the clutch cover 40 which extends in the radial direction and the first housing component 11.
- the gap seal 50 is also formed here between the clutch cover 40 and the second housing component 13.
- the gap seal 50 thus has a longer gap 51, in particular a longer gap 51 in the axial direction, than the gap 51 in the embodiment according to FIG. 8.
- FIG. 10 shows an enlarged section of an electric drive unit 1 according to the invention in the area of a gap seal 50 or a receiving space 60 according to a seventh embodiment.
- the section shown in FIG. 10 is essentially an alternative to the embodiment of an electric drive unit 1 according to the invention shown in FIG. 6.
- FIG. 10 differs from FIG. 6 by the configuration of the housing components 11, 13 in the area of the gap seal 50 or the receiving space 60 and by the arrangement of the receiving space 60.
- the receiving space 60 is formed here in the second housing component 13 as a depression in the side of the second housing component 13 facing the connection point 15.
- the connecting screw 16 is arranged on the first housing component 11 instead of on the second housing component 12.
- the receiving space 60 is fluidly connected by means of a channel 61 to the gap seal 50 or directly to the first housing interior 12.
- the channel 61 is arranged axially next to the sealing web 53, on its side facing away from the electrical machine 20. It is therefore positioned axially between the end region 41 of the clutch cover 40 which faces away axially from the electrical machine 20 and the first housing component 11, wherein it is delimited by the first housing component 11 on its side facing away from the electrical machine 20.
- the channel 61 represents the only opening 65 of the receiving space 60, with a further channel 64 being indicated in dashed lines, similar to FIG. 6, in addition to the channel 61.
- the further channel 64 is arranged here in the axial direction between the sealing element 52 and the sealing web 53.
- the further channel 64 realizes a fluidic connection with a receiving space other than the receiving space 60 shown here.
- the electric drive unit according to the invention thus has the advantage of requiring little installation space and requiring little installation effort, combined with reliable operation and a long service life.
