CONTINUOUSLY VARIABLE TRANSMISSION

摘要

A continuously variable transmission includes a first pulley, a second pulley, and an endless rotatable device operatively interconnecting the first and second pulleys. The endless rotatable device includes a device body and a plurality of device teeth protruding from the device body. Each of the first and second pulleys includes a first sheave, a second sheave, and a pulley axle operatively coupled between the first sheave and the second sheave. The pulley axle defines a pulley center. The first sheave is movable relative to the second sheave along the pulley axle. Each of the first and second sheaves includes a sheave body and a plurality of sheave teeth protruding from the sheave body. The sheave teeth are annularly arranged around the pulley center. The sheave teeth are shaped to mate with the device teeth.
