Abstract:
1. A parallel dual clutch device for arrangement in a drive train of a motor vehicle, between a drive unit and a transmission, which has a first multiplate clutch assigned to a first transmission input shaft and having a first plate assembly, a first actuating piston, a first inner plate carrier and a first outer plate carrier for selective torque transmission between the drive unit and the first transmission input shaft, and has a second multiplate clutch assigned to a second transmission input shaft and having a second plate assembly, a second actuating piston, a second inner plate carrier and a second outer plate carrier for selective torque transmission between the drive unit and the second transmission input shaft, wherein the actuating pistons have mutually opposed actuating directions wherein the inner plate carriers are each designed as the input side and the outer plate carriers are each designed as the output side of the first and second multiplate clutches wherein the first actuating piston is assigned a first pressure application chamber and the second actuating piston is assigned a second pressure application chamber, which are arranged on the mutually facing sides of the actuating pistons, wherein the pressure application chambers are separated from one another in the axial direction by a partition arrangement connected to a clutch main hub for conjoint rotation, said partition arrangement being formed, at least in the radially outer end section thereof, by two partition walls, which are spaced apart in the axial direction, are designed as formed sheet-metal parts, and on which the actuating pistons can be supported or are supported in the radial direction or in the axial direction.
