An automatic shift manual transmission equipped with a forward shifter for forward stage shifting, a reverse shifter for reverse stage shifting, an actuator rod carrying the forward shifter and the reverse shifter , and an actuator to operate the actuator rod according to shift operations of a shift lever, wherein a shifter length of the reverse shifter is substantially the same as the that of the forward shifter, and a reverse stage shift stroke is greater than a forward stage shift stroke by the difference in an operating measurement of the actuator rod.

Automatic shift type manual transmission

In a pulley arrangement of a belt-type continuously variable transmission, a ring member (6) integrated with a first cylinder member (3) is coupled to a second cylinder member (5) using splines (6d and 5c) to limit mutual movements of the first and second cylinder members and using snap ring (7) to limit the axial displacement therebetween in peripheral directions of the respective first and second cylinder members. The first cylinder member is slidably contacted on an outer peripheral surface of a hollow cylindrical portion of a second conical pulley component. The second cylinder member is fixed onto an outer peripheral surface of a shaft portion of a first conical pulley component. In addition, a another stopper is provided between an outer peripheral end of the hollow cylindrical portion (56d) and an inner peripheral surface of the second piston member (8) for limiting mutual movements of the second piston member and the hollow cylindrical portion in the peripheral directions of the second piston member and the hollow cylindrical portion.

Arrangement of pulley cylinder in a belt-type continuously variable

In a pulley working fluid (oil) passage arrangement for a belt-type continuously variable transmission having a V belt wound about a letter V-shaped groove formed with mutually opposing oblique surfaces of movable and stationary sheaves and a working fluid pressure cylinder chamber to which a working fluid pressure is supplied so as to move the movable sheave toward or away from the stationary sheave, thus a gear shift being varied, a first working fluid passage communicated with an axle chamber working fluid passage is extended in an axial direction of the axle member at an opposing surface thereof against the axle member and the movable sheave and a second working fluid passage having one end communicated with the first working fluid passage and the other end opened to a working fluid pressure cylinder chamber is extended along a radial direction of the axle member.
