Patent number: 11207965Abstract: A motor vehicle includes a transmission and a transmission fluid pump for transport of transmission oil to and within the transmission. The transmission fluid pump has a moving element which is coupled to a summation shaft of a planetary gear train. The planetary gear train has a ring gear which is operated by a first drive, and a sun gear which is operated by a second drive. A freewheel mechanism is arranged between the sun gear or a shaft connected to the sun gear and a further element so that the second drive can be switched off, when the first drive operates at high speeds while yet maintaining proper operation of the transmission fluid pump.Type: GrantFiled: April 12, 2017Date of Patent: December 28, 2021Assignee: AUDI AGInventors: Mario Schenker, Ralf Kischkat, Wilhelmus Gieles, Lionel Dumont

Patent number: 8631719Abstract: An arrangement of position transmitters on a selector rod for automatic speed change transmissions in motor vehicles, which interact with housing-mounted position sensors of an electrical speed detection circuit, at least one selector rod on its end regions being movably supported in cross walls of the housing of the transmissions and being actuated by means of a preferably electrohydraulically controlled speed selection unit where the selector rod projects through a through an opening in a cross wall of the transmission, which wall separates the oil compartment into the gear chamber which holds at least the speed selection unit and the position sensors, and the position transmitters are attached directly to the selector rod such that the selector rod with the position transmitters can be mounted through the through the opening as a mounting unit.Type: GrantFiled: June 22, 2007Date of Patent: January 21, 2014Assignee: Audi AGInventors: Christian Meixner, Mario Schenker, Johann Märkl

Patent number: 8546311Abstract: The present disclosure provides a fluid for lubricating the clutch-only portion of a wet clutch in a dual clutch transmission. The fluid provides high dynamic friction durability and comprises an oil of lubricating viscosity formulated with additive components comprising: i) at least one metal detergent; ii) at least one phosphorus-based wear preventative; iii) a phosphorylated and boronated dispersant different than the at least one phosphorus-based wear preventative; iv) a sulfurized extreme pressure agent; and a ratio between the content (ppm) of the sulfur based on the total weight of the fluid composition and a content (ppm) of phosphorus based on the total weight of the fluid composition ranging from about 2.0 to about 0.5 (ppm/ppm).Type: GrantFiled: March 10, 2009Date of Patent: October 1, 2013Assignees: Volkswagen Aktiengesellsschaft, Audi AGInventors: Joerg Fahl, Holger Gruenleitner, Mario Schenker, Ramnath N.

Patent number: 8151665Abstract: A shift device for a speed change transmission in motor vehicles having at least one selector rod which is movably supported in the gear housing in cross walls, by means of which rod the transmission steps in the gear housing can be shifted. The selector rod on one end penetrates a cross wall of the transmission, which wall separates the oil compartment, and by means of a plastic sleeve, which is sprayed onto the selector rod, is guided and sealed in the corresponding through hole of the cross wall of the transmission.Type: GrantFiled: June 22, 2007Date of Patent: April 10, 2012Assignee: Audi AGInventors: Christian Meixner, Mario Schenker, Johann Märkl
