    摘要: In an automatic transmission (AT) in which an input shaft (Input) and an output gear (Output) are disposed on the same axis and three clutches (C1-C3) and two brakes (B1, B2) are selectively operated to provide six forward speeds, first and second planetary gear sets (GS1, GS2) are configured to consistently reduce the speed of input rotation and output the speed-reduced rotation, thereby enabling downsizing of them. The first and second planetary gear sets (GS1, GS2) are arranged in a transmission case at both the axial ends thereof. Third and fourth planetary gear sets (GS3, GS4) are connected to each other to have four rotation elements in combination, thereby constituting a Simpson planetary gear train. One of the four rotation elements (a fourth carrier (PC4) in an illustrated example) is connected to the output gear (Output). Rotations input and reduced in speed by the first and second planetary gear sets (GS1, GS2) are input to sun gears (S3, S4) of the third and fourth planetary gear sets (GS3, GS4), respectively. First to third clutches (C1-C3) and a first brake (B1) are arranged to surround the first and second planetary gear sets (GS1, GS2).

    摘要: An automatic transmission is provided comprising a transmission case, a first shaft housed in and rotationally supported by said transmission case, and capable of receiving torque from an engine, a first shifting gear mechanism arranged coaxially with the first shaft, and a second shifting gear mechanism including a second planetary gear set. The second planetary gear set is housed within the transmission case and arranged coaxially with the first shaft, one of its sun and ring gears is capable of rotating together with the input shaft, and the other of the sun and ring gears is fixed to the transmission case. The automatic transmission further comprises first and second frictional elements arranged at least partly overlapped with the second planetary gear set in the axial direction between the planetary gear set and the transmission case in the radial direction. Accordingly, the plurality of frictional elements may be arranged on a shorter shaft without excessively increasing the radial size of the automatic transmission.
