Patent number: 7946630Abstract: A hydraulic system, especially for motor vehicles includes a master cylinder, a slave cylinder and a pressure medium line connected thereto. The invention provides a hydraulic system which is simple or economical to produce by virtue of the fact that the hydraulic system includes at least one hydraulic plug-type connection with a plug connector and a socket contact and the plug connector includes an abutment and a sealing element which are made of different materials and which are connected together in a material fit.Type: GrantFiled: May 13, 2003Date of Patent: May 24, 2011Assignee: Schaeffler Technologies GmbH & Co. KGInventors: Udo Popp, Roland Welter, Matthias Zink, Rudolf Hoenemann, Markus Heitbaum, Urban Panther, Jan Grabenstaetter

Patent number: 6695110Abstract: A torque-transmitting apparatus for motor vehicles includes a hydrokinetic torque converter with a housing connected to the driving shaft of an engine. The housing contains a pump and a turbine, the latter arranged to drive an input shaft of a power train. At least one damper is arranged in the power flow path between the turbine and a rotary output element of the apparatus. The damper has an input member constrained to rotate with the turbine and an output member connected to the rotary output element. The input member and the output member are rotatable relative to each other against the opposing forces of energy-storing devices arranged between the input member and the output member. The input member has a radially outer portion in form-locking engagement with the turbine.Type: GrantFiled: May 3, 2002Date of Patent: February 24, 2004Assignee: LuK Getriebe-Systeme GmbHInventors: Stephan Maienschein, Marc Meisner, Rudolf Hönemann

Patent number: 6659254Abstract: A clutch disc, particularly for use between a pressure plate and a counterpressure plate in a friction clutch which is installed in the power train of a motor vehicle, has two friction linings flanking resilient carriers mounted on a washer which has a hub connectable with a torque receiving part, such as the input shaft of a change-speed transmission. The carriers are connected with reinforcing sections of the friction linings by rivets in such a way that the friction linings and the washer are movable radially relative to each other. This reduces the likelihood of excessive wear upon the friction linings in response to repeated engagement and disengagement of the clutch.Type: GrantFiled: February 14, 2002Date of Patent: December 9, 2003Assignee: LuK Lamellen und Kupplungsbau Beteiligungs KGInventors: Martin Kraus, Hans-Dieter Elison, Rudolf Hönemann

Patent number: 6354413Abstract: The invention relates to hydrodynamic torque converter comprising a pump wheel which is arranged inside of a housing, a turbine wheel, a stator, a torque converter lock-up clutch and a torsional vibration damper. The turbine wheel has a turbine hub which is axially and rigidly mounted on a drive hub of the torque converter in an axial direction to the drive hub by means of at least one axial bearing. The turbine hub is mounted in a radial direction by means of a radial bearing. A connection with circumferential backlash is provided between the turbine hub and the drive hub by means of a disengaging gear. The invention also provides a rotationally fixed connection by means of an engaging gear located between the input component of the torsional vibration damper and the turbine hub, whereby the engaging gear and the disengaging gear are arranged on an essentially same axial position and radially within one another.Type: GrantFiled: March 13, 2001Date of Patent: March 12, 2002Assignee: LuK Lamellen und Kupplungsbau GmbHInventors: Jean-Francois Heller, Thomas Heck, Steven Olsen, Rudolf Hönemann

Patent number: 6273226Abstract: An improved apparatus and method for assembly of a hydrokinetic torque converter which comprises a hydraulic pump, a turbine, a stator, a driven hub, and a housing that is driven by the output element of an engine of a motor vehicle, and which functions to transmit torque to the hydraulic pump is disclosed. In such a torque converter the housing is coaxial with the pump and the turbine, and further defines an interior chamber, which encloses the turbine as well as a bypass or lockup clutch cooperating with a torsion damper having an input member and an output member.Type: GrantFiled: January 11, 2000Date of Patent: August 14, 2001Inventors: Rudolf Hönemann, Thomas Heck, Steven Olsen

Patent number: 6223872Abstract: The hydrodynamic torque converter (1) comprises a pump wheel (4) in a casing (2,3), a turbine wheel (5) and a turbine distributor (6). There is also a bypass coupling (70) including an axially moving piston, a torsional oscillations absorber (40) with input and output parts rotating relative to each other in opposition to force accumulators. Its turbine wheel comprises a hub (13) housed axially on the torque converter output hub (15). A connection with the rotational clearance, the splines (32,34), is provided between the two hubs. A fixed connection, by splines (34,41a) is between the input part of the absorber and the turbine wheel hub. The two sets of splines are in the same axial position radially one in the other.Type: GrantFiled: February 25, 2000Date of Patent: May 1, 2001Assignee: LuK Getriebe-Systeme GmbHInventors: Jean-Francois Heller, Thomas Heck, Steven Olsen, Rudolf Hönemann
