V-belt type continuously variable transmission

Abstract

Abstract PURPOSE:To improve the life of an actuator related member, reduce driving torque, and smoothly regulate transmission gear ratio by providing a spring energizing an input sheave on the movable side in the opposite direction to the axial force by a V-belt. CONSTITUTION:A roller holder 76 is fixed to an input sheave shaft 18 in the hollow cylinder part 40a of an input movable sheave 40 provided on the input sheave shaft 18 in such a manner as to be capable of sliding, and a compression coil spring 84 is interposed between the input sheave shaft and the inner surface of a conical part 40b. Thus, the axial force added to the input movable sheave 40 by a V-belt 60 is reduced by the compression coil spring 84, whereby the life of an actuator related member can be improved, driving torque can be reduced, and the transmission gear ratio can be smoothly regulated.
