Problems solved by technology

[0003] The known multi-clutch arrangements have proven themselves: a simple balancing of the hydraulic oil can be achieved, but the disadvantage is that both the first and the second clutches are subject to increased wear

Embodiment Construction

[0029] figure 1 A first embodiment of the multiple clutch arrangement 2 according to the invention is shown. The axis of rotation 4 of the multiple clutch device 2 is indicated by a dashed line. Furthermore, the opposite axial directions 6 , 8 , the opposite radial directions 10 , 12 and the opposite circumferential directions 14 , 16 of the multiclutch arrangement 2 are indicated by corresponding arrows.

[0030] The multiclutch arrangement 2 has a first clutch 18 and a second clutch 20 , with the result that the multiclutch arrangement 2 in the embodiment shown is a double clutch. Here, the first clutch 18 and the second clutch 20 are arranged in a nested manner in the radial direction 10 , 12 , that is to say the first clutch 18 surrounds the second clutch 20 from the outside in the radial direction 10 , For this reason, the first clutch 18 can also be referred to as an outer clutch, and the second clutch 20 can also be referred to as an inner clutch. This is also a conc...

Abstract

The present invention relates to a multiple clutch device (2) having a first clutch (18) which is assigned a first actuating piston (72) with a first pressure chamber (84) and a first pressure equalization chamber (82), and having a second clutch (20) which is assigned a second actuating piston (92) with a second pressure chamber (98) and a second pressure equalization chamber (102), a first crossflow channel (116) being provided for setting the hydraulic fluid column in the first pressure equalization chamber (82) and a second crossflow channel (118) being provided for setting the hydraulic fluid column in the second pressure equalization chamber (102). According to the invention, the first and second crossflow channels (116, 118) are arranged in such a way that both the oil which is discharged via the first crossflow channel (116) and the oil which is discharged via the second crossflow channel (118) can be fed to the first and second clutches (18, 20).

Description

technical field [0001] The invention relates to a multi-clutch arrangement having a first clutch equipped with a first actuating piston with a first pressure chamber and a first pressure balance chamber; and the multi-clutch device has a second clutch equipped with a second actuating piston with a second pressure chamber and a second pressure balancing chamber; providing A first cross flow passage sets the hydraulic fluid column in the first pressure balance chamber and a second cross flow passage sets the hydraulic fluid column in the second pressure balance chamber. Background technique [0002] A variety of hydraulically actuatable multiple clutch arrangements are known from the prior art, which are generally referred to as dual clutches. For example, the known double clutches comprise a first clutch and a second clutch, possibly actuated by an axially displaceable first actuating piston and by an axially displaceable second A piston is actuated to actuate the second cl...
