ABSTRACT:
A transmission for a motor vehicle comprises an input shaft connected to the crank shaft of an engine, an output shaft connected to a driving wheel, a V-belt stepless variable speed gear provided between the input and output shafts for providing different gear ratios of the input and output shafts on a stepless basis, and an interlocking transmission gear provided between the input and output shafts parallel to the stepless variable speed gear which, when operated, provides a constant gear ratio of the input and output shafts. A hydraulically operated first clutch of a normally-closed type is provided on the input shaft for operating the stepless variable speed gear when it is connected, and a hydraulically operated second clutch of a normally open type is provided on the output shaft for operating the interlocking transmission gear when it is connected. The hydraulic cylinders of the first and second clutches are allowed to alternately communicate with a hydraulic pump and an oil tank through a control valve.
