A torque transmitting device for transmitting torque between a first drive element and an output element, having a torque transmitting unit with a housing delimiting a first fluid chamber filled with a liquid, and a separating clutch arranged outside of the torque transmitting unit and the first fluid chamber in a second fluid chamber separated from the first chamber and which selectively transmits torque between the first drive element and the torque transmitting unit. The separating clutch has a clutch output that is connectable to a clutch input via a friction device and a clutch actuator that comprises a pressing element and an actuation element to which fluid pressure can be applied to move the actuation element. The pressing element is arranged within the second fluid chamber, and the actuation element is at least partly arranged within the first fluid chamber so that pressure is applied thereto by fluid pressure.

Torque transmitting device

A torque transmission apparatus for transmitting a torque between a first drive element and an output element, including a torque converter, having a torque converter input, which is rotatable about a rotation axis (A) and is coupled to the first drive element, and a torque converter output, which can be connected to the output element. A separating clutch arranged outside of the torque converter and effectively between the first drive element and the torque converter, having a clutch input and a clutch output, which can be connected thereto by the action of a clutch actuating apparatus. The clutch actuating apparatus having a pressure means chamber and a pressure means channel (K) supplying said pressure means chamber with pressure means, and the separating clutch being dry-operated and the pressure means channel (K) extending through the torque converter at least in portions.

The invention relates to a method for manufacturing a centrifugal pendulum () as well as a centrifugal pendulum () which is manufactured using said method and which comprises pendulum components () made of sheet metal, i.e. a pendulum mass support () that is arranged about an axis of rotation (d), and pendulum masses () that are distributed about the circumference. In order to reduce tool costs and the cost per item, at least one punched blank () comprising at least two pendulum components () is manufactured, whereupon the pendulum components () are separated from one another.

A hybrid module for a drivetrain of a motor vehicle includes a separating clutch for coupling an input-side drive shaft with an output-side intermediate shaft, and an actuating device for actuating the separating clutch, co-rotatable with the drive shaft or with the intermediate shaft. The actuating device includes a pressure chamber connectable to a pressure source arranged to provide a hydraulic actuating pressure through a hydraulic medium, and a compensation device for at least partially compensating a change in pressure in the pressure chamber from a first centrifugal force acting on the hydraulic medium. The drive shaft may be a crankshaft of an internal combustion engine arranged for mechanically driving the motor vehicle and the intermediate shaft may be a rotor shaft for an electric machine arranged for electrically driving the motor vehicle.
