Abstract

An actuator arrangement for a motor vehicle drive train which has at least one friction clutch for transmitting drive torque, in particular in the form of a starting clutch, as well as a gearbox having at least two gears, which can be engaged and disengaged by means of a shift clutch arrangement. The actuator arrangement comprises a hydraulic circuit that has a pump driven by means of an electric motor; a clutch hydraulic cylinder by means of which the friction clutch can be actuated; and a shift actuator device for actuating the shift clutch arrangement. The shift actuator device has a shift drum which is or can be coupled to the electric motor via a shift drum coupling device in a manner such that the shift drum can be set in rotation by means of the electric motor in order to actuate the shift clutch arrangement.
