Patent number: 7828688Abstract: The transmission has a plurality of members that can be utilized in powertrains to provide ten forward speed ratios and one reverse speed ratio. The transmission includes three planetary gear sets, six torque-transmitting devices, and two fixed interconnections. The powertrain includes an engine and torque converter that is continuously connected to one of the planetary gear members and an output member that is continuously connected with another one of the planetary gear members. The six torque-transmitting devices provide interconnections between various gear members, and the transmission housing, and are operated in combinations of three to establish ten forward speed ratios and one reverse speed ratio.Type: GrantFiled: July 9, 2007Date of Patent: November 9, 2010Assignee: GM Global Technology Operations, Inc.Inventors: Andrew W. Phillips, Scott H. Wittkopp, James M. Hart, Clinton E. Carey

Patent number: 7824302Abstract: A transmission having gearsets (RS1-RS4), shafts (1-8) and shifting elements (A-E). A carrier of gearset (RS4) and an input shaft forming shaft (1), a carrier of gearset (RS3) and an output shaft form shaft (2), sun gears of gearsets (RS3, RS4) form shaft (3). A ring gear of gearset (RS1) forms shaft (4). Ring and sun gears respectively of gearsets (RS2, RS1) couple as shaft (5), a carrier of gearset (RS1) and a ring gear of gearset (RS3) form shaft (6), sun and ring gears respectively of gearsets (RS2, RS4) couple as shaft (7). A carrier of gearset (RS2) forms shaft (8). Located in the flow of power: elements (A, B) are respectively between shafts (3, 4) and a housing, element (C) between shafts (5, 1), element (D) between shafts (8, 2) or (8, 6) and element (E) between two of shafts (5, 7, 8).Type: GrantFiled: March 15, 2006Date of Patent: November 2, 2010Assignee: ZF Friedrichshafen AGInventors: Gabor Diosi, Josef Haupt, Gerhard Gumpoltsberger, Peter Ziemer, Hagen Döpfert, Uwe Firzlaff, Martin Brehmer, Christoph Hutzel

Patent number: 7819773Abstract: An output side transfer member 103 of a second clutch C-2 extends around the outer circumferences of the output side transfer members 101, 102 of the third and first clutches C-3, C-1, the output side transfer member 104 (or 13, 101) of a fourth clutch C-4 and the output side transfer member 101 of a third clutch C-3 are linked to a sun gear S2, the output side transfer member 104 (or 13, 101) of a fourth clutch C-4, an output side transfer member 101 of a third clutch C-3, and a sun gear S2, which rotate integrally, are disposed radially inward with respect to the output side transfer member 102 of the first clutch C-1. Thereby, it becomes possible to reduce the diameter of the output side transfer member 104 (or 13, 101) of the fourth clutch C-4, to reduce the weight and inertia, and to improve the controllability of the automatic transmission 1.Type: GrantFiled: March 8, 2006Date of Patent: October 26, 2010Assignee: Aisin AW Co., Ltd.Inventors: Toshihiko Aoki, Minoru Todo, Kazuhisa Ozaki, Takuya Ishii, Satoshi Fukuyama, Tomochika Inagki, Yousuke Andoh

Patent number: 7803084Abstract: The transmission has a plurality of members that can be utilized in powertrains to provide eight forward speed ratios and one reverse speed ratio. The transmission includes four planetary gear sets having five torque-transmitting devices, three fixed interconnections and a grounded member. The powertrain includes an engine and torque converter that is continuously connected to at least one of the planetary gear members and an output member that is continuously connected with another one of the planetary gear members. The five torque-transmitting devices provide interconnections between various gear members, and with a stationary member, and are operated in combinations of three to establish at least eight forward speed ratios and at least one reverse speed ratio.Type: GrantFiled: October 5, 2007Date of Patent: September 28, 2010Assignee: GM Global Technology Operations, Inc.Inventors: Andrew W.
