Patent number: 8100809Abstract: A first element of a duplex planetary gear set is selectively coupled to an input shaft via a third clutch, or is selectively fixed via a first brake. A second element is selectively coupled, via a second clutch, to an intermediate shaft that is directly coupled to a speed-increasing element of a simplex planetary gear set which increases the rotational speed of the input shaft, or is selectively fixed via a second brake. A third element is directly coupled to an output shaft. A fourth element is selectively coupled to the input shaft via a first clutch. Therefore, by increasing the speed of the rotation of the input shaft by the simplex planetary gear set and transferring it to the duplex planetary gear set, it is possible to reduce the torques on individual components of an automatic transmission and therefore to reduce the sizes of the individual components and the capacities of the individual friction engagement elements.Type: GrantFiled: November 29, 2005Date of Patent: January 24, 2012Assignee: Aisin AW Co., Ltd.Inventors: Takao Taniguchi, Kazumasa Tsukamoto, Masahiro Hayabuchi, Akitoshi Katou, Satoru Kasuya, Naoji Katou, Hiroshi Katou, Masashi Kitou, Hiroaki Sanji, Naoki Takabayashi
