Publication number: 20230265908Abstract: A vibration damper with at least two absorbers, each having at least one spoke spring, enables efficient damping of the frequency response of a crankshaft. The absorbers preferably have different natural frequencies that are adapted to the frequency response of the crankshaft. The absorbers exhibit a frequency response, which is not or only insignificantly dependent on aging of the spoke springs and on the ambient temperature. The corresponding vibration dampers can be easily designed and mounted.Type: ApplicationFiled: February 21, 2023Publication date: August 24, 2023Applicant: Schaeffler Technologies AG & Co.

Publication number: 20070029156Abstract: The friction clutch between the prime mover and the change-speed transmission in the power train of a motor vehicle is actuatable by a slave cylinder cooperating with a master cylinder wherein the piston is movable by a clutch pedal or by an electric actuator. The casing of the slave cylinder is made, at least in part, of a plastic material and defines a plenum chamber arranged to receive pressurized fluid from the master cylinder by way of a conduit extending through a bell which contains the clutch and the slave cylinder. The annular piston of the slave cylinder surrounds the input shaft of the transmission. The plastic material of the casing of the slave cylinder can contain one or more additives which enhance its strength and/or influence its frictional engagement with the adjacent surfaces of the piston or of a lip seal which reciprocates with the piston.Type: ApplicationFiled: October 12, 2006Publication date: February 8, 2007Inventors: Axel Rogner, Manfred Jansen, Woflgang Fugel, Ulrich Helfmeier, Ernani Almeida, Dieter Adler, Uwe Abraham, Gerhard Meyer, Ludwig Winkelmann, Rainer Venz, Manfred Kraus, Peter Giese, Roland Welter, Jean-Francois Heller, Volker Lang, Wolfgang Sulger, Urban Panther

Patent number: 6769254Abstract: The piston of a master cylinder in the power train of a motor vehicle is made, at least in part, of a thermosetting plastic material and cooperates with one or more annular seals to ensure that a source of hydraulic fluid is communicatively connected with the chamber in the housing of the master cylinder when the piston is moved by one or more springs or otherwise in a sense to increase the volume of the chamber. When a pedal or another actuator causes the piston to expel pressurized fluid from the master cylinder into a slave cylinder, the seal or seals cooperates or cooperate with the housing and/or with the piston of the master cylinder to seal the source from the chamber of the master cylinder. The slave cylinder can actuate the friction clutch between the prime mover and the transmission in the power train of the motor vehicle.Type: GrantFiled: February 12, 2002Date of Patent: August 3, 2004Assignee: LuK Lamellen und Kupplungsbau Beteiligungs KGInventors: Jean-Francois Heller, Urban Panther, Jan Grabenstätter, Thomas Rammhofer, Roland Welter

Patent number: 6463954Abstract: A hydraulic control device for a transmission of a motor vehicle has a housing with a bore hole and a valve piston that is contained in the bore hole and slidable between different axial positions. The shift levels of the transmission are determined by setting the axial position of the valve piston. Prior to installation of the control device on another part of the motor vehicle, the valve piston is secured by a safety element against axial movement. Installation of the control device causes the safety element to release the valve piston.Type: GrantFiled: September 8, 2000Date of Patent: October 15, 2002Assignee: LuK Lamellen und Kupplungsbau Beteiligungs KGInventor: Urban Panther
