Title: MULTI-CLUTCH DEVICE AND HYBRID MODULE FOR A MOTOR VEHICLE
Abstract:
The invention relates to a multi-clutch device for a hybrid module, comprising a separating clutch (10) by means of which the torque of an internal combustion engine can be transmitted to the multi-clutch device and by means of which the multi-clutch device can be separated from the internal combustion engine; an additional clutch device (30) by means of which the torque of an electric machine and/or the separating clutch (10) can be transmitted to a powertrain, in particular a dual-clutch device comprising a first sub-clutch (40) and a second sub-clutch (50); a separating clutch actuation system (11) for actuating the separating clutch (10); an additional actuation system (31) for actuating the additional clutch device; a first rotational bearing (120); and a second rotational bearing (121). When the separating clutch actuation system (11) is actuated, the first rotational bearing (120) is loaded by the axial force produced by the separating clutch actuation system (11) solely in a first axial direction, and when the additional actuation system (31) is actuated, the second rotational bearing (121) is loaded by the axial force produced by the additional actuation system (31) solely in a second direction opposite the first axial direction. The multi-clutch device according to the invention has little bearing wear as a result of loading the rotational bearings on one side.
