ABSTRACT:
A mechanical synchronizer clutch selectively connects drive gears to an output shaft in response to movement of an actuator piston that pressurizes a hydraulic disc clutch following engagement of the synchronizer clutch with the gears. The disc clutch applies power to the gear train and removes torque therefrom so that the synchronizer clutch can produce engagement under no load. A variable diameter belt driven transmission produces an infinite range of speed ratios between the driven and the driving shaft. The driven shaft is coupled to an output shaft through the forward drive and reverse drive gear elements.
