Drehmomentabstützung eines Aktors an einem Kupplungsgehäuse/Getriebegehäuse

摘要

The invention relates to an actuating device for a motor vehicle, comprising an electromechanical actuator which has a spindle that can be set in a rotary movement by an electric motor, wherein said spindle can be coupled to a release device of a clutch via a motion conversion transmission that converts a rotational movement into a linear movement while transmitting pressure and/or traction to a pressure sleeve. The pressure sleeve thereby acts upon a clutch actuation device by means of a joint unit that secures the pressure sleeve against rotation. The invention also relates to a clutch having such an actuating device.
