ABSTRACT:
An automotive V-belt nonstage transmission includes a drive pulley having a fixed sheave fixedly mounted on a drive shaft, a movable sheave mounted on the drive shaft, a return coil spring, a flyweight mechanism, a collar being rotatable relative to the fixed and movable sheaves is mounted rotatably on the drive shaft, and a one-way clutch mounted between the collar and the drive shaft interlocks the collar and the drive shaft so that only the rotation of the collar in the normal rotating direction is transmitted to the drive shaft. The collar has an outer surface serving as a bottom surface of a V-groove defined by the respective conical pressure surfaces of the fixed and the movable sheave of the drive pulley, and a conical surface forming a central part, around the drive shaft, of the conical pressure surface of the fixed sheave of the drive pulley.
