Problems solved by technology

[0004] However, the embodiments known from the prior art have the disadvantage that the actuating device of the adjustable separating clutch is embodied with a relatively large structure
At the same time, the manufacturing and installation costs of the operating device and of the disconnecting clutch are relatively high
This can have a negative effect on the functionality or service life of the hybrid module

Embodiment Construction

[0023] The drawings are merely schematic in nature and are used only to aid in the understanding of the invention.

[0024] figure 1 A hybrid module 1 according to a preferred embodiment of the invention is shown. exist figure 2 In can be seen a complete, known through the background technology and its principle structure conforms to figure 1 The hybrid module 1' of the hybrid module 1 is shown. In particular, it should be pointed out that figure 1 Details not shown in detail with respect to the two partial clutches 12, 13 and their operation can be obtained from, for example, the figure 1 of the illustrated embodiment figure 2 Learned from.

[0025] Accordingly, the hybrid module 1 according to the invention has a housing 3 in which an electric motor 4 is arranged. The electric machine 4 of the hybrid module 1 has a stator 27 which is firmly connected to the housing 3 and a rotor 6 which is rotatable relative to the stator 27 . In this embodiment, the rotor rotati...

Abstract

The invention relates to a hybrid module (1) for a drive train (2) of a motor vehicle, comprising a housing (3), an electric machine (4) accommodated in the housing (3), an input shaft (5), a carrier(7) rotationally coupled to a rotor (6) of the electric machine (4), a disconnect clutch (8) operatively introduced between the input shaft (5) and the carrier (7), wherein the disconnect clutch (8) is arranged with multiple friction elements (9a, 9b) radially inside a sleeve-type torque transmission region (10) of the carrier (7) coupled to the rotor (6), a hydraulic actuation unit (11) providedfor engaging and disengaging the disconnect clutch (8), and two sub-clutches (12, 13) which each have multiple friction elements (9a, 9b) arranged radially inside the torque transmission region (10) of the carrier (7), and which are rotationally fixed to the carrier (7) by their first clutch component (14b, 14c), wherein the actuation unit (11) has a hydraulic conduit (15) which is hydraulically coupled to an actuating piston (16) accommodated inside the housing (3) on the input shaft (5), and which is introduced into the input shaft (5), forming, at least in part, a rotary union. The invention also relates to a drive train (2) comprising said hybrid module (1).

Description

technical field [0001] The invention relates to a hybrid module suitable for use in a (hybrid) powertrain system of a motor vehicle, such as a passenger car, truck, bus or other commercial vehicle, said hybrid module comprising a housing; accommodated in said housing A motor in the motor; an input shaft; a bracket rotationally coupled with a rotor of the motor; a disconnect clutch effectively installed between the input shaft and the bracket, wherein the disconnect clutch with a plurality of friction elements radially Arranged inside a sleeve-shaped torque transmission area of ​​the carrier coupled to the rotor; a hydraulically operated device for engaging and disengaging the separating clutch is provided; and two partial clutches each having a plurality of The friction element is arranged radially within the torque transmission region of the carrier and is connected in a rotationally fixed manner to the carrier by means of its first clutch assembly. In addition, the present ...
