A gearshift mechanism for a motor vehicle with hydraulically actuated multiple clutch, particularly a twin clutch, has a first gear input shaft to drive a first group of gears and a second gear input shaft to drive a second group of gears. The two gear input shafts are each assigned a clutch unit being coaxial to one another. A stationary housing accommodates the two clutch units. At its end face, the housing can be closed off by a housing cover that has a central opening through which a drive hub of a clutch cage is guided. The housing cover is provided with a bearing flange around the central opening, on the outside of which the clutch cage is supported. This advantageously supports the clutch on the housing and makes it possible to achieve a support effect for a dual mass flywheel or the crankshaft end of the internal combustion engine.

A torsion damping mechanism with a torsion damper with an input side and an output side, where the input side and the output side are connected elastically to each other by spring-type stored energy elements for rotation in common auxiliary mass which can rotate coaxially to the torsion damping mechanism is connected frictionally to the torsion damping mechanism by way of a friction area, where the frictional connection between the torsion damping mechanism and the auxiliary mass has a predetermined frictional moment. When this moment is exceeded during the occurrence of peaks in the torque being applied to the torsion damping mechanism, the auxiliary mass can slip or slips.

A clutch operator arrangement for introducing an actuating force into a friction clutch includes a ball screw arrangement.

Clutch operator arrangement

A leaf spring arrangement, especially for connecting a pressure plate to a housing, comprises a plurality of adjacent leaf spring elements, where each leaf spring element has a first attachment area for establishing the connection the pressure plate, a second attachment area for establishing the connection to the housing, and a connecting area extending between the first attachment area and the second attachment area. At least certain areas of at least two of the leaf spring elements are spaced apart between their first attachment area and their second attachment area.

A ball screw includes a spindle element which has a first groove arrangement on an outer circumferential surface, a nut element which surrounds the spindle element and has a second groove arrangement on an inner circumferential surface, and a plurality of balls, at least some of which engage into the first groove arrangement and the second groove arrangement. The nut element is rotatable about an axis of rotation with respect to the spindle element, and, during the rotation of the nut element about the axis of rotation with respect to the spindle element, the balls which engage into the first groove arrangement and the second groove arrangement roll in the first and the second groove arrangement, while at the same time rotate about respective ball axes of rotation. In this case, there is provision, with respect to the ball axis of rotation, for an effective ball rolling radius with which the balls roll in the first groove arrangement to be smaller than the effective ball rolling radius with which the balls roll in the second groove arrangement.

A pressure plate assembly for a friction clutch includes a housing arrangement and a pressure plate arrangement, which is held by at least one leaf spring arrangement with freedom of axial movement relative to the housing arrangement. The at least one leaf spring arrangement is fixed by a first attachment area to a first fastening area of the pressure plate arrangement and by a second attachment area to a second fastening area of the housing arrangement. The end area of the first fastening area and/or the second fastening area curves away from the minimum of one leaf spring arrangement, this end area being located in the area along which the at least one leaf spring arrangement extends.

A torsion damping mechanism with a torsion damper with an input side and an output side, which are connected elastically to each other by spring-type stored-energy elements, and with an auxiliary mass which can rotate coaxially to the torsion damper. A combination bearing has a first bearing section for supporting the input side and the output side against each other, and a second bearing section for supporting the auxiliary mass.
