    摘要: Herein disclosed is a brake system for use with an automatic transmission for braking a rotatable member such as a brake drum, which is accommodated in a casing and connected to the sun gear or the like of a planetary gear mechanism, by bringing a brake band having two ends into contact with the outer circumference with the rotatable member. The brake system comprises: a cylinder tube so held in a predetermined position in the casing as to move forward and backward in the tangential direction of the rotatable member; a piston fitted in the cylinder tube; a piston rod united with the piston and projecting from the cylinder tube such that it is connected to one end of the brake band; an anchor rod so held in a predetermined position in the casing as to move forward and backward in the tangential direction of the rotatable member and conneced to the other end of the brake band; a connecting member for connecting the cylinder tube and the anchor rod so tha they may move together forward and backward; and a valve mechanism disposed in the cylinder tube and adapted to be opened, when the cylinder tube is moved by a force received in a predetermined direction from the brake band through the piston rod to either apply a fluid pressure in a direction to reduce the fastening force by the brake band or release the fluid pressure.

    摘要: A control apparatus for a vehicle for a continuously variable transmission (CVT) whose speed ratio is continuously variable, the apparatus including a mode selector responsive to a currently required output of an engine, for selecing one of a continuously variable speed mode in which the speed ratio of the CVT is continuously changed, and a stepping shift mode in which the speed ratio is changed in a plurality of steps. The apparatus further includes a first control device operable in the continuously variable speed mode, for continuously changing the speed ratio of the continuously variable transmission so as to operate the engine with minimum fuel consumption, and a second control device operable in the stepping shift mode, for selecting one of a plurality of speed-ratio positions corresponding to the above-indicated plurality of steps, and for maintaining the selected speed-ratio position, based on the detected currently required output of the engine and the detected running speed of the vehicle.

    摘要: An automatic transmission including gear trains, which are constructed of at least three planetary gear sets each having three rotating members. A first clutch is arranged closer to an input shaft than the first planetary gear set for connecting any one of the rotating members of the first planetary gear set arranged adjacent to the input shaft. A second clutch is also arranged closer to the input shaft than the first planetary gear set for connecting another of the rotating members of the first planetary gear set and the input shaft. A third clutch is interposed between the first planetary gear set and the second planetary gear set for connecting any one of the rotating members of the second planetary gear set arranged at the opposite side to the input shaft across the first planetary gear set and the any one or the another of the rotating members of either one of the first clutch and the second clutch or the first planetary gear set. A fourth clutch is interposed between the first planetary gear set and the second planetary gear set for connecting the another of the rotating members of the second planetary gear set and the any one or the another of the rotating members of the first clutch, the second clutch or the first planetary gear set.
