Patent number: 7937925Abstract: A drive chain suitable for use in a continuously variable transmission of a motor vehicle, the transmission having two pairs of spaced drive members about which the chain passes to transfer torque from one drive member to the other. The chain includes a plurality of link elements that include spaced, side-by-side plate links. The plate links include openings in which pairs of parallel rocker members are disposed for relative rocking movement of at least one rocker member about its longitudinal axis. A method for stretching the chain is also disclosed, in which areas of some of the plate links are plastically deformed by stretching the chain before the chain is put to use.Type: GrantFiled: January 21, 2008Date of Patent: May 10, 2011Assignee: LuK Lamellen und Kupplungsbau Beteiligungs KGInventors: André Linnenbrügger, Oswald Kroninger, Klaus Scheufele, André Teubert

Patent number: 7048657Abstract: A transmission with a drive side and an output side conical disk pair. One conical disk pair includes a fixed disk carried by a shaft, a movable disk non-rotatably connected with and axially movable relative to the shaft, and a support ring axially attached to the shaft adjacent a back side of the movable disk. A pressure chamber between the support ring and the back side of the movable disk is supplied with hydraulic pressure medium through a passage in the shaft that opens to the surface of the shaft. An end region of the movable disk when moved along the shaft passes over the opening at a maximum spacing of the movable disk from the fixed disk, and a hydraulic medium connection exists between the passage and the pressure chamber through drainage slots between an inner surface of the movable disk and the peripheral surface of the shaft.Type: GrantFiled: January 15, 2005Date of Patent: May 23, 2006Assignee: Luk Lamellen und Kupplungsbau Beteiligungs KGInventors: Hartmut Faust, Eric Müller, Klaus Scheufele, Werner Gruca

The rocker members extend outwardly beyond the plate links and are retained in position by retaining members that engage particular rocker members. A method for stretching the chain is also disclosed in which areas of some of the plate links are plastically deformed before the chain is put to use.Type: GrantFiled: November 30, 2001Date of Patent: January 13, 2004Assignee: LuK Lamellen und Kupplungsbau Beteiligungs KGInventors: Klaus Scheufele, Werner Gruca

Patent number: 6293887Abstract: A plate link chain of the present invention has rocker link elements configured such that the frictional end surfaces have a profile, which deviates from a planar surface in both circumferential and radial orientations. In a preferred embodiment the end surface profiles are defined by radii of predetermined dimensions in the range of 5 to 50 millimeters with the radius formed in the radial plane being larger than the radius formed in the circumferential plane. The radii originate from midpoints, which are located at predetermined distances from the rocking surfaces, to form substantially spherical end surfaces that are either symmetric or asymmetric for selected applications. The substantially spherical end surfaces are designed to reduce the edge transfer forces and tracking error of the rocker link elements and to improve wear characteristics and the stability of frictional engagement of the transmission in operation.Type: GrantFiled: February 4, 2000Date of Patent: September 25, 2001Assignee: LuK Lamellen und Kuppungsbau GmbHInventors: André Linnenbrügger, André Teubert, Klaus Scheufele
