Abstract

A drive unit for a motor vehicle includes an electric machine which has a stator, a rotor and clutch for producing a rotary driving connection of the rotor to a drive element. The clutch has a release member which is axially displaceable by an actuating device arranged at least partially in a receiving space surrounded by the stator. The actuating device has an electric actuator drive motor and an actuator drive shaft directed transverse to the axis of rotation of the drive unit. The actuator drive shaft is operatively connected to a release arrangement which includes a rotatable input element which is fixed axially relative to the release member and an output element which is axially displaceable relative to the input element and which is operatively connected to the release member.
