Patent number: 8739930Abstract: A gearbox for a motor vehicle is provided that includes, but is not limited to an input shaft, an output shaft and a plurality of wheel sets for coupling input and output shaft with different transmission ratios and a gear pump, which is arranged to for delivering from a reservoir of the gearbox. The gear pump is an outer gear pump and one of two gears of the gear pump meshing with one another belongs to one of the wheel sets.Type: GrantFiled: August 18, 2008Date of Patent: June 3, 2014Assignee: GM Global Technology Operations LLCInventors: Jörg Bönning, Jan Sporleder

Patent number: 8126623Abstract: A shifting device is provided for the gear selection in a manual transmission that includes, but is not limited to a shift/selector lever that can be moved in a shifting degree of freedom and a selection degree of freedom, a measuring sensor for measuring a current position (s, w) of the shift/selector lever in the two degrees of freedom, a two-dimensionally controllable actuator device and a control circuit for the controlling of the actuator device in a position (S, W) which is associated with the sensed position (s, w) of the shift/selector lever, which depicts the movement region of the shift/selector lever on a region of possible positions of the actuator device. The movement region of the shift/selector lever included, but is not limited to a two-dimensional prohibited part region, in which the shift/selector lever is simultaneously moveable in both degrees of freedom.Type: GrantFiled: February 6, 2009Date of Patent: February 28, 2012Assignee: GM Global Technology Operations LLCInventors: Christian Rübsam, Jan Sporleder

Patent number: 8113082Abstract: An external gear shift for the gear selection in a manual transmission is provided that includes, but is not limited to a gearshift/selector lever, which is guided in a link plate and which is movable along a selector track and a plurality of shifting tracks, and a measuring sensor to detect an instantaneous position (s, w) of the gearshift/selector lever. Guide fingers of the link plate disposed between shifting and selector tracks each have flanks oriented obliquely to the shifting and selector tracks.Type: GrantFiled: February 6, 2009Date of Patent: February 14, 2012Assignee: GM Global Technology Operations LLCInventors: Christian Rübsam, Jan Sporleder

Publication number: 20120006643Abstract: A double-acting synchronizer includes, but is not limited to a shaft, first and second gearwheels rotatably mounted on said shaft, a sleeve which is axially displaceable along said shaft between a position in which it locks the first gearwheel to the shaft and a position in which it locks the second gearwheel to the shaft. A single conical friction surface is formed between a first baulk ring and the first gearwheel, and multiple nested conical friction surfaces are formed between a second baulk ring and the second gearwheel.Type: ApplicationFiled: January 22, 2010Publication date: January 12, 2012Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Jan Sporleder, Joerg Appelshaeuser, Hans-Juergen Zuck, Theodore Kokx

Patent number: 8019519Abstract: A shift-by-wire control unit is provided that includes, but is not limited to a sensor for detecting the position of a shift lever, which is movable on a path between a neutral position and at least one shift position, a control circuit, and an actuator for driving a selector fork in accordance with a movement of the shift lever detected by the control unit. The control circuit is set up to predefine a setpoint position of the actuator for each detected position of the shift lever, the rate of change of the setpoint position as a function of the shift lever position being higher in a first area of the path adjacent to the neutral position than in a second area of the path, which is at a greater distance from the neutral position than the first area.Type: GrantFiled: December 8, 2008Date of Patent: September 13, 2011Assignee: GM Global Technology Operations LLCInventors: Christian Ruebsam, Jan Sporleder

Publication number: 20110214522Abstract: A shifting clutch includes, but is not limited to a synchronizer body rotationally fixed on a shaft, a first and a second gear wheel, at least two synchronizing rings, a shifting sleeve which is displaceable over a neutral position on the synchronizer body in axial direction of the shaft between a first and a second shifted position, in which it establishes a non-positive connection between synchronizer body and the first or second gear wheel, and at least one thrust piece which is displaceable over a neutral position through the shifting sleeve between a first and a second synchronizing position, in which it loads the first or second synchronizing ring in each case against the first or second gear wheel. The shifting sleeve comprises at least one inwardly directed projection which in the first shifted position restricts the axial freedom of movement of the thrust piece.Type: ApplicationFiled: March 7, 2011Publication date: September 8, 2011Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Jan Sporleder, Joerg Appelshaeuser
