Abstract

A multiple clutch device which includes a drive unit, a downstream transmission connected to a drive shaft of the drive unit and accommodated in a clutch bell that does not co-rotate with the drive shaft, two wet multi-plate clutches, which include a plate support at the input and output end and plates alternating axially, and an actuation mechanism. A housing of the actuation mechanism is supported on the clutch bell, and the plate support at the input end of at least one of the multi-plate clutches is connected to the housing by a supporting metal sheet or a supporting pot and a footstep bearing such that a flow of an actuation force generated by the actuation mechanism is redirected to the housing of the actuation mechanism via the supporting metal sheet or the supporting pot and the footstep bearing, thus creating a closed force flow within the device.

Dependent claims

A multiple clutch device for a drive train which has a drive unit with a drive shaft and a following transmission, the device comprising:

a transmission housing, which is not corotatable with the drive shaft of the drive unit, the device being connectable to the drive shaft of the drive unit and received in the transmission housing;
two multi-plate clutches each have an input-side plate carrier, an output-side plate carrier and plates alternating in an axial direction;
an actuating device having a housing supported radially on the transmission housing via a bearing block;
and
a support sheet or a support pot and a supporting hearing arranged so as to connect the input-side plate carrier of at least one of the multi-plate clutches to the housing of the actuating device such that a force flux of an actuating force generated by the actuating device is returned to the housing of the actuating device by the support sheet or the support pot and the supporting hearing, so that the force flux, which is closed within the multiple clutch device, is present.
