Abstract
An actuator arrangement for a clutch of a drive train for motor vehicles. The clutch is prestressed into an opened position and can be activated electromechanically. An electric motor can be coupled to the clutch in order to activate it. A control unit actuates the electric motor. The actuator arrangement has a safety device which is connected to the electric motor parallel to the control unit. The safety device is configured, in the case of a fault state, to supply electrical power to the electric motor independently of the control unit in order to open the clutch.
