Abstract
This invention relates to a continuously variable transmission which increases the range of potential transmission ratios and thereby decreases the fuel consumption rate, and which is compact in size and thereby increases space in a passenger compartment. The continuously variable transmission has low and high gear trains and a reverse gear train. Each of the low and high gear trains has a pair of meshed gears and a one-way clutch which controls the direction of transmitting the generated torque. The high gear train further has a clutch which engages at a medium or high vehicle speed and disengages at a low vehicle speed. A jaw clutch is slidably mounted on an output shaft and is located in either a first position or a second position. The jaw clutch forms the low gear train when the jaw clutch is in the first position, and the reverse gear train when the jaw clutch is located on the second position.
