Patent number: 6966286Abstract: A method for equalizing the filling of cylinders of a multi-cylinder internal combustion engine (14) comprising a fully variable mechanical valve train (20) having an adjusting shaft (1) that controls the valve lift of the inlet valves of a cylinder bank and can be rotated together with its rotationally fixed adjusting cam (2) by an electromechanical actuator (3) whereby an equalization of the filling of the individual cylinders is achieved by the fact that filling-dependent engine data are measured by a sensor (16) while the engine (14) is running and are processed using suitable software in a control device (15) into signals with which the actuator (3) rotates the adjusting shaft (1) selectively for each cylinder in keeping with the opening phase and thus regulates the lift and the time cross-section of the individual inlet valves and, as a consequence, also the filling of the individual cylinders to a desired set value.Type: GrantFiled: May 20, 2004Date of Patent: November 22, 2005Assignee: INA-Schaeffler KGInventor: Ulrich Grau

Patent number: 6767305Abstract: An actuating unit for use on an electromechanically actuated disc brake for automotive vehicles including a drive unit or an electric motor, an actuating element for actuating one of two friction linings displaceably arranged in a brake caliper, and a first and a second reducing gear. The first reducing gear is comprised as a ball screw, while a planetary gear is used as the second reducing gear. To increase the efficiency, the present invention discloses a coupling shaft used to transmit forces from the planet cage of the planetary gear to the threaded spindle of the ball screw. The ends of the coupling shaft form universal joints with the planet cage and the threaded spindle.Type: GrantFiled: September 27, 2002Date of Patent: July 27, 2004Assignees: Continental Teves AG & Co., oHG, Ina-Schaeffler KGInventors: Wendelin Backes, Alexander Zernickel, Juergen Hartmann, Ulrich Grau, Werner Dorsch, Peter Rieth, Johann Jungbecker, Stefan Schmitt, Ralf Schwarz, Oliver Hoffmann, Joachim Nell

Patent number: 6684831Abstract: The invention concerns an electrically rotatable shaft, and more particularly, an adjusting shaft (1) of a fully variable mechanical valve train of an internal combustion engine, said shaft comprising an adjusting cam (2). The low-friction and lash-free configuration of a drive required for a rapid and exact functioning of the fully variable mechanical valve train is achieved by the fact that the adjusting shaft (1) is rotated by an actuator (3) that comprises an adjusting lever (4) connected rotationally fast to the adjusting shaft (1), while the free end of the adjusting lever is articulated preferably on the screw nut (10) of a screw-and-nut drive (5) that is driven by an electromotor (6).Type: GrantFiled: April 24, 2002Date of Patent: February 3, 2004Assignee: INA-Schaeffler KGInventor: Ulrich Grau
