Patent number: 11788584Abstract: 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.Type: GrantFiled: July 23, 2020Date of Patent: October 17, 2023Assignee: Schaeffler Technologies AG & Co. KGInventors: Stephan Maienschein, René Daikeler, Christian Hügel

Patent number: 11407300Abstract: 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.Type: GrantFiled: August 27, 2019Date of Patent: August 9, 2022Assignee: Schaeffler Technologies AG & Co.
