Patent number: 11225132Abstract: A hybrid module for a powertrain of a motor vehicle includes a rotational axis defining an axial direction, a housing, first and second support bearings, an intermediate shaft, a separating clutch, and a sensor device. The second support bearing is arranged at a distance from the first support bearing in the axial direction to form a receiving space therebetween. The intermediate shaft is mounted by the first support bearing and the second support bearing to be rotatable relative to the housing about the rotational axis. The separating clutch has a rotary component arranged to be coupled to an electric machine, and connected for conjoint rotation with the intermediate shaft. The sensor device includes at least one part arranged in the receiving space.Type: GrantFiled: February 6, 2018Date of Patent: January 18, 2022Assignee: Schaeffler Technologies AG & Co.

Patent number: 8733522Abstract: A dual clutch and a method for controlling the same in a drive train of a motor vehicle which has two friction clutches that transmit a torque from an internal combustion engine to respective transmission input shafts of a dual clutch transmission and which have a common counterpressure plate firmly connected to a crankshaft of the internal combustion engine and two contact plates that are fixed in terms of rotation relative to the counterpressure plate and can be moved axially by respective lever springs supported on a housing part firmly connected to the counterpressure plate. To limit the axial installation space for the dual clutch, the lever springs for actuating the friction clutches are actuated radially on the inside in the same direction by respective actuating systems in the case of a change from one friction clutch to the other of a torque to be transmitted via the friction clutches.Type: GrantFiled: June 7, 2011Date of Patent: May 27, 2014Assignee: Schaeffler Technologies AG & Co.
