ABSTRACT:
Disclosed is a continuously variable transmission. The continuously variable transmission includes a propulsion controller connected to an engine crankshaft; a forward/reverse controller mounted on an input shaft extending from the propulsion controller and which determines whether the vehicle is driven in forward or reverse modes; a low/high-speed selector connected to an output of the forward/reverse controller, for selecting a low-speed or a high-speed driving state; a continuously variable device connected to a first output of the low/high-speed selector; and a drive power synthesizer connected both an output of the continuously variable device, and to a second output of the low/high-speed selector.
