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.
Clutch arrangement for a motor vehicle drive train, wherein the clutch arrangement has a first and a second clutch which are embodied as normally open clutches, wherein the first clutch can be activated from an open position into a closed position by means of a first actuator arrangement, and wherein the second clutch can be activated from an open position into a closed position by means of a second actuator arrangement, and wherein the clutch arrangement has a locking device for locking the second clutch in the closed position,
Drive train for a motor vehicle, wherein the drive train has a drive engine and a step-by-step variable speed transmission which has a plurality of gearspeed stages and a first and a second component transmission which, by means of a clutch arrangement, can be shifted into a power flux and whose outputs are connected to a driven axle, wherein the clutch arrangement has a first and a second clutch which are embodied as normally open clutches, wherein the first clutch can be activated from an open position into a closed position by means of a first actuator arrangement, and wherein the second clutch can be activated from an open position into a closed position by means of a second actuator arrangement, and wherein the clutch arrangement has a locking device for locking the second clutch in the closed position, wherein 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, such that the first actuator arrangement has to be supplied with energy in order to secure the first clutch in the closed position, wherein the first clutch can shift the first component transmission into the power flux, and wherein the second clutch can shift the second component transmission into the power flux, and wherein the clutches can be activated in an overlapping fashion in order to carry out a gearspeed change.
Method for actuating a clutch arrangement, wherein the clutch arrangement has a first and a second clutch which are embodied as normally open clutches, wherein the first clutch can be activated from an open position into a closed position by means of a first actuator arrangement, and wherein the second clutch can be activated from an open position into a closed position by means of a second actuator arrangement, and wherein only the second clutch can be locked in the closed position by means of a locking device, while the first clutch cannot be locked in the closed position, such that the first actuator arrangement has to be supplied with energy in order to secure the first clutch in the closed position.
