ABSTRACT:
A power transmission for driving a vehicle wherein a high-low speed changer is disposed between an engine and a primary speed change mechanism. The speed changer comprises a planetary gear mechanism provided between an input shaft and an output shaft, a speed increasing clutch for causing the gear mechanism to effect a speed increase, and a direct coupling clutch for coupling the input shaft to the output shaft via the gear mechanism without speed change. Since the torque transmitted to the speed change mechanism is small, the transmission can be compact in its entirety.
