Abstract: An actuator and clutch assembly for a power transmission device includes a first and second clutch members arranged to selectively define a connected state of the clutch when the second clutch member is drivingly engaged with the first clutch member and a disconnected state of the clutch when the second clutch member is not drivingly engaged with the first clutch member. An electric motor drives an input member driven for rotation about an axis, and an output member is driven axially relative to the input member when the input member rotates, wherein the second clutch member moves axially with the output member. A spring provides a force on the output member that biases the output member in a direction in which the second clutch member is moved toward the first clutch member. The spring is radially and axially overlapped by the input member and the output member.

Abstract: A dual clutch arrangement for a transmission that is provided with a first input shaft and a second input shaft has a clutch housing that is connectable to a drive train in a rotationally fixed fashion. The first and second friction clutches can transmit a torque between the clutch housing and the first and the second input shafts, respectively. The first and second friction clutches are nested in the radial direction with respect to each other and actuated by a first and a second actuating unit that have pistons for pressuring clutch disk packs. The compressive force exerted by the piston of the first actuating unit and the compressive force exerted by the piston of the second actuating unit are directed in axially opposite directions with respect to each other.
