A hybrid drive module, comprising an annular diaphragm spring having an inner surface and one or more fingers protruding radially inward from the inner surface and a carrier hub concentric with the diaphragm spring and connected to a rotor of an electric motor and a cover of a torque converter, the carrier hub having an outer surface with one or more retention grooves configured to interlock with the one or more fingers of the diaphragm spring to inhibit axial movement of the diaphragm spring relative to the carrier hub.

In a clutch release bearing device, an inner ring (12) of a ball bearing (10) is pressed against a diaphragm spring (40) so that a clutch is disengaged. A contact member (20) made of steel is press-fitted to the inner ring (12) so that a convex spherical protruding portion (20b) formed at an end portion of the contact member (20) is brought into contact with the diaphragm spring (40). In addition, a contact position (C) between the protruding portion (20b) and the diaphragm spring (40) is located between an extension line of an inner diameter (D1) of the inner ring (12) and an extension line of an outer diameter (D2) of the inner ring (12).

The present invention relates to an actuating device for a clutch having a stator device, a rotor device which is rotatable in relation to the stator device and a carriage device which is movable to a limited extent in an axial direction in relation to the rotor device and which supplies tensile and thrust forces, which is operatively connected to a push-pull device that is designed to exert tensile and thrust forces on a lever element of the clutch, where the push-pull device has at least one pull element and at least one push element, between which the lever element can be accommodated, and which are connectible to one another, as well as to a clutch having an actuating device, an electric drive module having a clutch, and a method for installing a clutch having an actuating device.
