Patent number: 8052561Abstract: A method for optimizing the link plates of a plate-link chain drive chain for use in a variable speed unit of a belt-driven conical-pulley transmission. The chain includes plate links formed from pairs of plates that have openings through which pairs of rocker members extend. The plates include longitudinally-extending legs that extend in the chain movement direction and vertical legs that extend perpendicular to the chain movement direction. The method is directed to minimizing bending stresses in the longitudinal and vertical legs of the plates as the chain passes around a pulley, and as the rocker members and the chain tension impose forces on the plates. The stress minimization results in minimal material usage and minimal weight of the chain.Type: GrantFiled: April 10, 2003Date of Patent: November 8, 2011Assignee: LuK Lamellen und Kupplungsbau Beteiligungs KGInventors: Wolfgang Oberle, André Teubert

Patent number: 7493203Abstract: A method for regulating or controlling the transmission ratio of an automatic power-branched transmission. Power is transmitted through a shaft driven by an engine, a variable speed drive, a gear transmission, a driven shaft, and at least two control clutches. The variable speed drive and the gear transmission are connected to each other in such a way that the regulating range of the variable speed drive is traversed in one direction within a first range of transmission ratios, and is traversed in the opposite direction within a second range of transmission ratios during traversing of the entire range of transmission ratios. The shifting strategies result in reduced wear of the endless belt device and allow for comfortable changing between the transmission ratio ranges.Type: GrantFiled: January 27, 2003Date of Patent: February 17, 2009Assignee: LuK Lamellen und Kupplungsbau Beteiligungs KGInventors: Franz Bitzer, Christian Lauinger, Michael Reuschel, Martin Vornehm, André Teubert, Manfred Homm, Eric Müller, Reinhard Stehr, Bernhard Walter

Publication number: 20080176693Abstract: A plate-link chain for a belt-driven conical-pulley transmission having a continuously variable transmission ratio. Individual rocker joints that join chain links formed by plate sets are designed as pairs of rocker members inserted into openings in the plates and having rolling surfaces that bear against each other. Three plates lying side-by-side in the transverse direction of the plate-link chain and which are associated with three adjacent chain links in the longitudinal direction of the plate-link chain, form a plate subsequence. Outer plates of a plate subsequence in the transverse direction of the plate-link chain are situated in the same chain link with an outer plate of an adjacent plate subsequence that is adjacent in the transverse direction of the plate-link chain.Type: ApplicationFiled: December 15, 2007Publication date: July 24, 2008Applicant: LuK Lamellen und Kupplungsbau Beteiligungs KGInventor: Andre Teubert

Publication number: 20070111832Abstract: A method for controlling the adjustment of a continuously variable transmission in which pairs of conical disks are adjustable relative to each other so that transmission ratios can be set continuously between first and second shafts on which the respective conical disk pairs are positioned. In respective absolute end positions of the adjustable disks the transmission ratio assumes an extreme value. A control system provides that in a first adjustment range the adjustable disks are always kept within relative end positions that are at least at a defined distance from the absolute end positions. In a second operating state, the adjustment of the adjustable disks is controlled in such a way that the adjustable disks can be moved within a second adjustment range over the entire adjustment distance to the absolute end positions, so that in the second operating state a maximum possible spread of the transmission is utilized.Type: ApplicationFiled: September 30, 2006Publication date: May 17, 2007Applicant: LuK Lamellen and Kupplungsbau Beteiligungs KGInventors: Michael Reuschel, Andre Teubert, Andreas Englisch

Patent number: 7204775Abstract: A plate-link chain formed from short plate links and long plate links. The long plate links have an extension at one end. The installation direction of the long plate links is such that their extensions overlap plate links in an adjacent row and that are next in order in the longitudinal direction of the plate-link chain, when viewed from the side of the chain. The overlap permits the plate links to have defined positions relative to adjacent plate links by minimizing the ability of adjacent plate links to shift laterally relative to each other.Type: GrantFiled: February 13, 2004Date of Patent: April 17, 2007Assignee: LuK Lamellen und Kupplungsbau Beteiligungs KGInventors: André Teubert, André Linnenbrügger

Patent number: 7179184Abstract: A link chain for use in the continuously variable transmission of the power train in a motor vehicle is assembled of pairs of composite identical or dissimilar links each having a stack of apertured plates, and of coupling units employing pairs of non-circular pins extending through registering portions of apertures in the respective stacks of plates. The pins are designed to cooperate with the plates to limit the extend of inward and outward pivotability of links of the respective pairs from positions of alignment, and the pins carry stops which act alone or cooperate with diaphragm springs or with other types of springs to prevent wobbling of the plates. The plates can be provided with projections which cooperate with the pins to limit the extent of pivotability of the pairs of links relative to each other and/or to prevent jamming of pairs of links in angular positions from which they cannot return to the positions of alignment. Each plate is traversed by two pairs of pins.Type: GrantFiled: July 25, 2003Date of Patent: February 20, 2007Assignee: Luk Lamellen und Kupplungsbau Beteiligungs KGInventors: André Linnenbrügger, André Teubert
