Description

The present invention relates to a hybrid module for the drive train of a motor vehicle. In particular, the hybrid module comprises an electric machine having a stator and a rotor. The rotatable about an axis rotor has at least one rotor carrier. On an outer periphery of the rotor carrier a plurality of magnetizable elements are provided, which are arranged opposite to the stator. A separating clutch is mounted in the rotor of the electric machine on the rotor arm. A double clutch is the electrical machine nach- and upstream of a gearbox. The dual clutch consists of a first partial clutch and a second partial clutch, wherein the first partial clutch is positioned in the radial direction closer to the axis of the hybrid module, as the second partial clutch.

The German patent application DE 10 2009 059 944 A1 also relates to a hybrid module for a powertrain of a vehicle. The hybrid module sits in a drive train of a vehicle. The powertrain of a vehicle consists of an internal combustion engine, the hybrid module and the transmission. According to one exemplary embodiment of the prior art, the hybrid module is disclosed with a separating clutch and an electric machine consisting of stator and rotor in conjunction with a double wet clutch connected downstream of the hybrid module. The double wet clutch consists of a radially outer partial clutch and a radially inner partial clutch, wherein the separating clutch and the dual clutch are arranged in a common closed wet space.

Disadvantage of wet clutches when using a hybrid module are their increased costs and their insufficient efficiency.

The invention has for its object to provide a hybrid module for the drive train of a motor vehicle, which is inexpensive, has a short axial space and has a good thermal coupling between the couplings used and the electric machine. Furthermore, the assembly of the hybrid module should be simple and have individual testable units.

The above object is achieved by a hybrid module for the drive train of a motor vehicle, comprising the features of claim 1.

A hybrid module for the powertrain of a motor vehicle includes an electric machine that consists of a stator and a rotor. The rotor is designed to be rotatable about an axis and has a rotor carrier which carries on an outer circumference a plurality of magnetizable elements which are arranged opposite to the stator. The hybrid module comprises a separating clutch, which is mounted in the rotor of the electric machine on the rotor carrier. Likewise, a double clutch is provided, which has a downstream of the electric machine and a transmission upstream first partial clutch and second partial clutch. The first sub-clutch is positioned closer to the axis in the radial direction than the second sub-clutch. The first separating clutch, the first partial clutch and the second partial clutch of the double clutch are designed as dry clutches. One carrier plate holds the separating clutch and the second partial clutch on the rotor carrier. With the carrier plate, a clutch cover is connected, which holds the first part clutch and the second part clutch.

The advantage of this hybrid module is that it achieves a short axial space requirement. Likewise, a good thermal coupling between the dry separating clutch and the dry double clutch and the electric machine is given. Also achieved by the present invention is a simple assembly of the individual elements of the hybrid module, which in turn affects the cost of the hybrid module lowering and also leads to a robust design of the hybrid module.

The carrier plate for fastening the separating clutch and the second partial clutch is connected via a screw connection to the rotor carrier. The support plate is u. a. also for heat dissipation between the couplings and the electric machine.

The screw connection can be designed such that the counter plate of the separating clutch, the carrier plate and the rotor carrier are interconnected. Alternatively, a counter-plate of the second partial clutch instead of the carrier plate of the separating clutch can be fixed by this screw. It is also possible for both counterplates to be connected by this screw connection to the carrier plate and the rotor carrier. It makes sense to use several fasteners distributed around the circumference. These fasteners can then connect different numbers of components and / or different components of the hybrid module.

The stability of the carrier plate can be improved by conical regions adjacent or between the radially extending regions (disk-shaped regions) and the axially extending regions (cylindrical regions).

When the support plate in the region extending in a predominantly axial direction radially below the magnetizable elements (magnets) of the extends in the region extending in a predominantly radial direction adjacent to the electrical machine, having no openings or only has openings which are closed during operation of the hybrid module by other components, protects the support plate made of sheet metal from the heat of Clutch, the pad wear of the clutch discs and / or other emissions of the clutches (clutch and dual clutch). The protection of the electric motor is in addition to the holders of the couplings another important task of the support plate.

The carrier plate holds the separating clutch. For this purpose, a pressure plate of the rotor carrier and the counter-plate are usefully connected in a rotationally fixed manner to the carrier plate and are axially supported by the latter. The counter-plate is firmly connected to the carrier plate. The pressure plate is limited axially displaceable connected to the support plate. The support plate may additionally serve as a mounting or supporting element for other components of the separating clutch, such as lever springs, disc springs, leaf springs or adjusting rings, which serve for attachment and or actuation of the pressure plate and / or as adjustment elements and / or energy storage. It is possible that the carrier plate so comprehensively supports the disconnect clutch or the disconnect clutch components that the disconnect clutch only via the support plate, the mechanical connection to their actuation system and by the connection of the disconnect clutch disc to the shaft in operative connection with other parts of the hybrid module Active compound is.

According to another Augestaltung all components of the first part of the clutch and the second part clutch are attached to the clutch cover. Thus, the dual clutch is already a functional and independently of the other parts of the rest of the hybrid module testable unit. This unit is thus already given before the attachment of the clutch cover to the support plate. This facilitates the assembly and testing process. If both the pressure plate and the counter plate of the second sub-coupling are attached to the clutch cover, the axially displaceable pressure plate can be arranged both on the clutch cover facing side of the clutch disc and on the carrier plate facing side of the clutch disc. The counter-plate is always located on the other side of the clutch disc as the pressure plate and can thus support the force exerted by the pressure plate on the clutch disc axial force.

The carrier plate may consist of a first sub-plate and a second sub-plate. The separating clutch is supported by the first sub-plate and the second sub-clutch through the second sub-plate on the rotor arm.

The disconnect clutch can be actuated from the side of an engine coupled to the hybrid module. The first part clutch and the second part clutch of the double clutch can be operated from the side of the transmission forth.

For the actuation of the first separating clutch and the second separating clutch of the double clutch, in each case a concentric slave cylinder, each with a corresponding engagement bearing can be provided.

According to one embodiment, a concentric slave cylinder is provided for the actuation of the separating clutch, which is integrated in a housing of the hybrid module together with an engagement bearing of the concentric slave cylinder. For the actuation of the separating clutch a plurality of openings in the direction of the axis of the hybrid module are formed in the rotor bar. A pressure pot is designed such that it passes through the openings and can interact with the separating clutch in operative connection, when the separating clutch associated concentric slave cylinder is actuated.

The separating clutch can be designed in single or multi-disc design. The first part clutch and the second part clutch of the double clutch can also be designed in single or multi-disc design.

The actuation of the double clutch from the transmission side can also be carried out via a corresponding engagement bearing and several mechanical levers. Likewise, the concentric slave cylinder for the operation of the motor-side clutch in the hybrid module housing can be integrated. The separating clutch and the first part clutch and the second part clutch of the double clutch can be directly operated or operated with clutch internal power amplification. The clutch internal power amplification can, for. B. by a lever spring or more distributed on the circumference of the couplings single lever can be achieved.

If all components of the first part clutch 21 and second part clutch 22 on the clutch cover 34 are fixed, represents the double clutch 1 already a functional and independent of the other parts of the remaining hybrid module 5 testable unity and that before the clutch cover 34 on the carrier plate 30 is attached.

8th describes the way of screwing the from the three clutches (separating clutch 2 , first part clutch 21 , second part clutch 22 ) existing unit with the rotor arm 12 , This assembly concept allows the mounted electrical machine 4 and the completely assembled assembly of the three clutches (separating clutch 2 , first part clutch 21 , second part clutch 22 ) in an easy way to connect. The carrier plate 30 and the clutch cover 34 which already has the separating clutch 2 and the double clutch 1 wear, are doing with the rotor arm 12 of the rotor 11 connected in one operation. These are in the clutch cover 34 , as well as in the clutch disc 22L the second part clutch 22 the double clutch 1 passages 26 designed to be an actuator 39 with the screw connections 36 can be brought into effect. At the in 8th In the embodiment shown, the screw connections are sufficient 36 even through the counter-plate 46 the separating clutch 2 , The counter plate 46 and the carrier plate 30 are in this embodiment, even before the connection through the screw 36 mounted and thus connected captive together. The counter plate 46 is already held in position before the clutches (disconnect 2 and double clutch 1 ) to the electric machine 4 be screwed.

An alternative mounting option for the carrier plate 30 with the separating clutch 2 on the rotor carrier 12 is that the carrier plate 30 with the disconnect clutch attached 2 on the rotor carrier 12 is screwed on. Subsequently, the double clutch 1 with the clutch cover 34 on the carrier plate 30 attached.

Another alternative mounting option shows 3 , The attachment point between the carrier plate 30 and the electric machine 4 takes place in this embodiment on a much smaller radius than in the other embodiments. screw 41 connect the rotor bar 15 with the radially inwardly extending region 30R the carrier plate 30 axially behind the separating clutch 2 , This allows a fully assembled electric machine 4 and a completely assembled assembly of the three clutches (separating clutch 2 , first part clutch 21 , second part clutch 22 ) along the axis A put together and then screwed. This is done in which the screws 41 through openings 62 a supporting wall 60 of the hybrid module 5 put through and tightened. After the screw connection between the rotor bar 12 and the support plate 30 has been tightened, the openings become 62 in the supporting wall 60 , through the previously the tool, the screws 41 screwed, protruding, with lids (not shown) closed. This assembly concept allows the attachment of the complete assembly from the three couplings (separating clutch 2 , first part clutch 21 , second part clutch 22 ) on the electric machine 4 without the coupling assembly having mounting holes that allow access to the fasteners (or joints).

Although in the preceding figures, which serve to describe the invention, the support plate 30 and the rotor carrier 12 seemingly touching each other over a large area, it makes sense to the touch points on the technically necessary places too restrict. It makes sense to touch the carrier plate 30 the rotor carrier 12 at the attachment points, which also take the axial exact alignment of the two parts to each other. In addition, even radial centering are useful, the exact radial alignment and centering of the support plate 30 and the rotor carrier 12 ensure each other. In all other places is reasonably some distance between the support plate 30 and the rotor carrier 12 designed so that the heat transfer from the couplings (separating clutch 2 , first part clutch 21 , second part clutch 22 ) on the electric machine 4 is reduced. If further contact points are nevertheless necessary, these should be as small as possible and also as far as possible from the magnetizable elements 14 be distant. The separating clutch 2 , the first part clutch 21 and / or the second part clutch 22 can be designed as single-disc clutches, as a multi-disc clutch or as multi-disc clutches with any number of slats.

The invention has been described in terms of preferred embodiments. However, it will be understood by those skilled in the art that changes and modifications may be made without departing from the scope of the following claims.
