    • A compact automatic transmission for a vehicle capable of preventing increase in relative rotational speed between shift elements. A planetary gear unit is provided with a sun gear to which rotation of an input shaft is input, a carrier that can be stopped from rotating, and a ring gear for outputting, to a planetary gear set, rotation that is reduced in speed relative to that of the input shaft. A clutch is connected/disconnected, the input shaft and the sun gear are appropriately connected/disconnected, and the carrier is appropriately stopped/unstopped by a brake and a one-way clutch. This prevents relative rotational speed between shift elements of the gear unit that does not participate in a shifting operation from excessively increasing. When the clutch is disposed between the input shaft and the sun gear, the torque capacity of the clutch can be reduced as compared with the case where it is disposed between the gear unit and the gear set. Therefore, the clutch can be formed into a more compact structure and the overall automatic transmission can be made more compact.
    • 一种用于车辆的紧凑型自动变速器,其能够防止变速元件之间的相对转速增加。 行星齿轮单元设置有输入轴的旋转的太阳齿轮,可以停止旋转的载体,以及用于向行星齿轮组输出相对于行星齿轮组减速的旋转的齿圈 输入轴的。 离合器连接/断开,输入轴和太阳齿轮适当地连接/断开,并且载体被制动器和单向离合器适当地停止/停止。 这防止了不参与换档操作的减速器的换档元件之间的相对转速过度增加。 当离合器设置在输入轴和太阳齿轮之间时,与设置在减速器和齿轮组之间的情况相比,可以减小离合器的扭矩能力。 因此,离合器可以形成为更紧凑的结构,并且可以使整体自动变速器更紧凑。

    • In a four wheel drive vehicle, this torque distribution device includes a friction engaging mechanism which controls drive torque distribution to the front vehicle wheels and/or to the rear vehicle wheels, and a servo device which receives an actuating hydraulic fluid pressure and which applies an engaging force to the friction engaging mechanism so as to cause it to be able to transmit torque. The engaging force for the friction engaging mechanism and the maximum torque transmission capacity thereof this provided both increase monotonically according to increase of the actuating hydraulic fluid pressure. This servo device includes first and second pistons which partially serve to define respective first and second pressure chambers, and which, when impelled by hydraulic fluid pressure in their respective first and second pressure chambers, both provide such engaging force for the friction engaging mechanism. When actuating hydraulic fluid pressure is supplied to two different combinations of the first pressure chamber and the second pressure chamber, the relationships between the magnitude of the engaging hydraulic fluid pressure and the engaging force for the friction engaging mechanism and the maximum torque transmission capacity of the friction engaging mechanism differ. The combinations may be the individual pressure chambers by themselves, or may be one of the chambers and the two of them together. A three stage specialization of this device, and the method of operation thereof, are also described.
