Embodiment Construction

[0034] Combine Figure 1 to 6 In detail seen a first embodiment of the multi-plate clutch as a friction clutch of the present invention is implemented 1. Further aid Figure 7 to 10 Illustrate two further embodiments, however, these two further embodiments of structure and function in accordance with the principles of a multi-plate clutch of the first embodiment. For brevity, therefore only the differences between the embodiments set forth in the following embodiments.

[0035] returnfigure 1 It can be seen that the multi-plate clutch 1 according to the present invention is used in the mixing module 2 or is formed into a component of the mixing module 2. Furthermore, the mixing module 2 is used in a typical manner in the power assembly 3 of the motor vehicle. The power assembly 3 illustrates the two transmission input shafts 26a, 26b side of the transmission in this view. The transmission input shaft 26a, 26b is connected to the output side of the mixing module 2, as described in de...

Abstract

The invention relates to a multi-disc clutch (1) for a hybrid module (2) of a motor vehicle drivetrain (3), having a first clutch component (4a) and a second clutch component (4b) which can be coupled as desired to the first clutch component (4a) for conjoint rotation, wherein the first clutch component (4a) has a first carrier (7) which is provided for connection to a rotor (5) of an electric machine (6) for conjoint rotation and has a first group (8) of frictional elements (9a, 9b, 9c) which is connected to the first carrier (7) for conjoint rotation, and the second clutch component (4b) has a second carrier (10) and a second group (11) of frictional elements (12a, 12b) which is coupled to the second carrier (10) for conjoint rotation, wherein the frictional elements (9a, 9b, 9c) of the first group (8) are arranged in alternation with the frictional elements (12a, 12b) of the second group (11) next to one another in an axial direction of a common rotational axis (13), wherein a first frictional element (9a) of the first group (8), which first frictional element is connected in an axially fixed manner to the first carrier (7), is connected to a second frictional element (9b) of the first group (8) for conjoint rotation via a driver element (14) which is held for conjoint rotation and in an axially relatively displaceable manner on the first frictional element (9a) of the first group (8). The invention also relates to a hybrid module (2) and a dual clutch device (30), each designed with a multi-disc clutch (1). The invention also relates to a drivetrain (3).

Description

Technical field [0001] The present invention relates to a motor vehicle, the hybrid module multiplate clutch powertrain as cars, trucks, buses, or other utility vehicle / vehicle powertrain, said multi-plate clutch, preferably as friction disc clutch achieve multiple disk clutch having a first clutch part and a second clutch for selectively rotationally fixed portion coupled to the first clutch, of which the first clutch part having a motor for preparing a first carrier member and the rotor is connected rotationally fixed to the first friction element carrier rotationally fixedly coupled to the first group and the second clutch part having a second carrier and a second carrier member rotationally fixed with the a friction coupling elements of the second group, and wherein the frictional member of the first group are arranged alternately side by side with a friction member of the second clutch in the axial direction of the common axis of rotation. Further, the present invention rel...
