摘要： A second planetary gear unit PR and a clutch C1 for outputting reduced speed rotation are located on one axial side of a first planetary gear unit PU, with an output unit located therebetween. A clutch C2 which connects/disconnects an input shaft 2 to/from a sun gear S2 of the planetary gear unit PU and a clutch C3 connects and disconnects the input shaft to/from a carrier CR2 of the planetary gear unit are on the other axial side of the first planetary gear unit PU. Compared with a transmission wherein a clutch C2 or clutch C3 is located between the second planetary gear unit PR and the planetary gear unit PU, the second planetary gear unit PR and the first planetary gear unit PU can be located closer together, and a member which transmits the reduced speed rotation can be made shorter. Further, compared to the case wherein, for example, the clutches C1, C2, C3 are located together on one axial side, oil supply to their servos is simplified.

摘要： A vehicular automatic transmission is provided with a reduction planetary gear for reducing and outputting an inputted rotation of an input shaft, first and third clutches for enabling the transmission of a reduced rotation reduced through the reduction planetary gear, a planetary gear unit having second and third sun gears to which the reduced rotation is transmitted by the first and third clutches, and a fourth clutch for enabling the transmission of the inputted rotation to the second sun gear. The fourth clutch is linked to the second sun gear of the planetary gear unit via output side members, i.e., a clutch drum and a link member, of the third clutch, to commonly use as the output side members.

摘要： A reduction in the weight and size of a speed-change mechanism is obtained by shortening a high-torque transmission system. The speed-change shock is attenuated by reducing an inertia torque in a muilti-stage vehicular automatic transmission. The vehicular automatic transmission is equipped with a planetary gear set that receives a decelerated rotation and a non-decelerated rotation as inputs and outputs a plurality of speed-change rotations, a reduction planetary gear, an input shaft that passes through an inner side of the planetary gear set, first and third clutches that couple the input shaft to two different speed-change elements of the planetary gear set respectively through the reduction planetary gear in an engageable and disengageable manner, and a second clutch that couples the input shaft to the other speed-change element of the planetary gear set in an engageable and disengageable manner. The reduction planetary gear and the third clutch for transmitting a high torque are arranged on one side of the planetary gear set, whereas the first clutch for transmitting a high torque is arranged on the other side of the planetary gear set.
