Multiple clutch for a motor vehicle, particularly for a hybrid drive of a motor vehicle

Abstract

The invention relates to a multiple clutch (1) for a motor vehicle, particularly for a hybrid drive of a motor vehicle, comprising at least one first, one second and one third separating clutch (K1, K2, KO), the first separating clutch (K1) being provided for coupling a first transmission input shaft (2) to a drive (4 or 5) or uncoupling same therefrom, the second separating clutch (K2) being provided for coupling a second transmission input shaft (3) to a drive (4 or 5) or uncoupling same therefrom, where the first and second separating clutches (K1, K2) are embodied as multiple-plate clutches and comprise an inner plate carrier (6, 7) and an outer plate carrier (8a, 8b), and the third separating clutch (KO) being provided for coupling the outer plate carrier (8a, 8b) of the first and second separating clutches (K1, K2) to a drive (4 or 5) or uncoupling same therefrom, the third separating clutch (KO) being embodied as a multiple-plate clutch, the outer plate carrier (8a, 8b, 8c) of the first, the second and the third separating clutches (K1, K2, KO) being embodied as a common outer plate carrier (8) for receiving, supporting and / or guiding the outer plates (10, 11, 12) of the first, second and third separating clutches (K1, K2, KO), and the actuating piston of the middle separating clutch (K1) has a double bearing.

Description

technical field [0001] The invention relates to a multiple clutch for a motor vehicle, in particular for a hybrid drive of a motor vehicle, according to the features of the preamble of patent claim 1 . Background technique [0002] Multiple clutches for motor vehicles, in particular also for hybrid drives of motor vehicles, are already known from a large amount of prior art. [0003] Usually, such multiple clutches have a first, a second and a third separating clutch, which are designed in particular as friction multi-disk clutches. In this case, the first separating clutch is provided for coupling or decoupling the first transmission input shaft to a drive, in particular to an internal combustion engine and / or to an electric motor. In particular in the case of a double clutch transmission, a second separating clutch is then provided, which is provided for coupling or decoupling the second transmission input shaft thus provided with a drive, in particular with an internal c...

AI Technical Summary

Problems solved by technology

On the one hand, the construction and assembly complexity of the known multiple clutches is increased, in particular different discs, in particular differently configured and / or differently dimensioned, have to be produced in part for the first and second separating clutches and also for the third separating clutches optimized friction linings, which also have to be arranged or positioned accordingly in several assembly steps

This results in high cost

Furthermore, the cooling oil system is not yet optimal in the case of already known multiple clutches or multiple clutch systems

Due to the complex spatial arrangement of the corresponding inner and outer plate carriers of the first, second and third separating clutches, partly complex cooling oil channels have to be formed or realized, which in turn increases the manufacturing costs accordingly
