Patent number: 11519377Abstract: A method actively dampens a start-up resonance of a torsional damper when starting an internal combustion engine. The torsional damper (4) is fixed between an internal combustion engine (1) and a secondary side (5) of a torsional elasticity, and the internal combustion engine (1) is started using a starter generator (3) arranged on a side of the internal combustion engine (1) counter to the torsional elasticity. A counter excitation is applied to a torque generated by the starter generator (3) when the internal combustion engine (1) is started, which counter excitation is modulated on the basis of a parameter of the internal combustion engine (1) which changes when the internal combustion engine (1) is being started.Type: GrantFiled: December 10, 2019Date of Patent: December 6, 2022Assignee: Schaeffler Technologies AG & Co. KGInventors: Thorsten Krause, Kai Schenck, Bertrand Pennec

Patent number: 10060516Abstract: An oil-flooded single-plate or multi-plate lockup clutch is provided in a torque transfer device. The torque transfer device may, for example, be a converter, a dual clutch, a starting clutch, a manual shifter, or power shifting clutch, having a piston to engage the clutch and a damper. In accordance with the present disclosure, the piston together with a housing of the torque transfer device forms a closed pressure chamber when the clutch is engaged and at least one oil flow opening is provided in the piston in an area outside of the pressure chamber. The torque transfer device preferably has a damper and the piston of the clutch forms a part of the damper and may be designed as a retainer for springs of the damper.Type: GrantFiled: July 13, 2016Date of Patent: August 28, 2018Assignee: SCHAEFFLER TECHNOLOGIES AG & CO.

Patent number: 9038793Abstract: Centrifugal pendulum device including pendulum masses arranged on axial sides of a pendulum mass support rotatable about an axis of rotation to form a pendulum mass pair. To form the mass pair, the masses are fastened to each other by means of a fastener passing through a cutout in the mass support. The mass pair is pivotable relative to the mass support due to a rolling element arranged to roll in a recess of the mass support and of the mass. In a section axially covering the recess of the mass support, the rolling element has a first outer diameter. In a section axially covering the recess of the pendulum mass, the rolling element has a second outer diameter. The rolling element further comprises a section axially located between the first and second diameters and has a third diameter, which is smaller than or equal to the first outer diameter.Type: GrantFiled: February 11, 2013Date of Patent: May 26, 2015Assignee: Schaeffler Technologies AG & Co.

Publication number: 20070181396Abstract: A three-channel torque converter in which an additional wall is mounted, thereby creating a third space which hydraulically connects the end of the plates that faces away from the turbine to a third channel. This third space ensures that an exchange flow of oil in a region of the hydrodynamic components (impeller, turbine, stator), of an optional damper, and of the lockup clutch is always restricted to flow across the plates of the lockup clutch. This provides high-performance cooling of the plates in the slip mode.Type: ApplicationFiled: January 11, 2007Publication date: August 9, 2007Applicant: LuK Lamellen und Kupplungsbau Beteiligungs KGInventors: Stephan Maienschein, Mario Degler, Bruno Mueller, Kai Schenck
