Abstract:
A belt-type continuously variable transmission (CVT) with reduced vibration at high engine speeds. A secondary sheave includes a fixed sheave member, a moving sheave member, a compression coil spring, and an outside spring guide. The compression coil spring urges the moving sheave member toward the fixed sheave member. The outside spring guide prevents the compression coil spring from buckling during compression.
