Patent number: 8500582Abstract: A plate-link chain for a motor vehicle drive system including conical pulleys. The chain includes a number of link plates hingedly connected with each other by rocker members. The rocker members extend transversely to the longitudinal direction of the chain and within openings in the link plates. The rocker members and link plates bear against each other along curved contact surfaces to transmit power. Rocker member pairs roll against each other on facing curved rolling surfaces at a contact point that moves from an upper area above the center of mass of the rocker member cross section to a lower area below it. The ratio of the distance from the end of the upper area to the center of mass and the distance from the end of the lower area to the center of mass lies in a range of from about 1.1 to about 2.Type: GrantFiled: June 2, 2007Date of Patent: August 6, 2013Assignee: Schaeffler Technologies AG & Co.

Patent number: 8495875Abstract: A turbocharger for an internal combustion engine, in which a mechanical energy flow can be generated from an exhaust gas flow of the internal combustion engine for providing engine intake airfow under pressure. The turbocharger includes a mechanical energy converter connected between the exhaust gas flow and the intake airflow, by which converter the mechanical energy flow can be transferred and transmitted. The turbocharger also includes an electrical energy converter associated with the mechanical energy flow for converting mechanical energy into electrical energy, or vice versa, to enable improved intake airflow charging of an internal combustion engine. By means of the electrical energy converter, an electrical energy flow can be selectively branched off to a battery or fed into the mechanical energy flow.Type: GrantFiled: August 6, 2010Date of Patent: July 30, 2013Assignee: Schaeffler Technologies AG & Co.

Patent number: 7909723Abstract: An adjusting device including a CVT planetary roller transmission having two axially-spaced sun wheels that are rotatable about a common axis of rotation and at different speeds of rotation. Planet wheels contact and ride against peripheral surfaces of each of the sun wheels, and an axially displaceable ring wheel lies radially outwardly of the sun wheels and engages a peripheral groove formed in the sun wheels. When the ring wheel is axially displaced relative to the sun wheels the axes of rotation of the planet wheels tilt relative to the sun wheel axis resulting in a difference in the rotational speed of the sun wheels changes. The device can be employed as an adjusting device for adjusting the rotational speed of connected units, and also as a drive line component having a variable transmission ratio and situated in a power train of a motor vehicle.Type: GrantFiled: January 24, 2008Date of Patent: March 22, 2011Assignee: LuK Lamellen und Kupplungsbau Beteiligungs KGInventors: Andreas Triller, Andreas Englisch, Andreas Götz, Lászlo Mán, Marco Grethel
