Abstract

Clutch arrangement for a motor vehicle drive train. The clutch arrangement has a first and a second clutch which are embodied as normally open clutches. The first clutch can be activated from an open position into a closed position by means of a first actuator arrangement. The second clutch can be activated from an open position into a closed position by means of a second actuator arrangement. The clutch arrangement has a locking device for locking a clutch in the closed position. Only the second clutch can be locked in the closed position by means of the locking device, while the first clutch cannot be locked in the closed position. Thus, the first actuator arrangement has to be supplied with energy in order to secure the first clutch in the closed position.
