Continuously variable transmission

摘要

A continuously variable transmission is provided with an adjustable pulley assembly including two sheaves on a pulley shaft, at least one sheave is axially movable with respect to the pulley shaft by a hydraulically operated movement, the movement includes a piston/cylinder assembly for generating a first force acting on the movable sheave and centrifugal pressure compensator for generating a second force acting on the movable sheave in a direction opposite with respect to the first force; the centrifugal pressure compensator includes a further cylinder fixed to the axially movable sheave in radial direction beyond the piston/cylinder assembly, and a further piston fixed to the pulley shaft, the further piston and the further cylinder form a further piston/cylinder assembly.
