ABSTRACT:
A power transmission comprises a belt type continuously variable ratio-change mechanism CVT and a fixed ratio rotational transmission mechanism GT, which transmit the rotational driving force of a primary shaft1rotationally driven by an engine to a countershaft3with a speed ratio change. The continuously variable ratio-change mechanism comprises a drive pulley10, a driven pulley15and a metal belt14while the fixed ratio rotational transmission mechanism GT comprises a forward drive gear train, a forward output transmission gear train, and a reverse drive gear train. The forward drive gear train transmits the rotation of an input drive gear31on the primary shaft1through an idler gear32to a LOW driven gear33on a secondary shaft2, and the forward output transmission gear train transmits the rotation of the secondary shaft2to the countershaft3. The reverse drive gear train transmits the rotation of the input drive gear31through the idler gear32to a reverse driven gear36on the countershaft3.
