Actuating arrangement, in particular for coupling an internal combustion engine to a drive train of a hybrid motor vehicle, and use of an actuating arrangement

摘要

It is an actuating arrangement (14), in particular for coupling an internal combustion engine to a drive train of a hybrid motor vehicle, provided with an axially displaceable actuating element (28) for introducing an actuating force for actuating a friction clutch (12), in particular of the type a lever element (22) designed to axially displace a pressure plate (20) of the friction clutch (12) and a support element (24) which is rotationally fixed in the circumferential direction relative to the lever element (22) for pivotally supporting the lever element (22 ), wherein the lever element (22) on the support element (24) about a circumferentially extending pivot point at a support point (26) of the support member (24) is pivotally supported, wherein the support member (24) for axial displacement of the support point (26) movable is configured, in particular for increasing a clearance of the friction Clutch (12) with open friction clutch (12) and to reduce the clearance of the friction clutch (12) with closed friction clutch (12). The supporting element (24) can displace the support point (26) provided for the pivotable mounting of the lever element (22) in the axial direction by means of relative movement relative to the lever element (22) in the circumferential direction in order to close the clearance when the friction coupling (12) is closed to reduce and at an opening of the friction clutch (12) to increase their clearance, so that in a friction clutch (12) in a drive train of a motor vehicle at a short actuation a high contact force in the closed state of the friction clutch (12) without significant drag torque in the open state the friction clutch (12) is possible.
