BELT TYPE CONTINUOUSLY VARIABLE TRANSMISSION

摘要

PROBLEM TO BE SOLVED: To provide a belt type continuously variable transmission improving transmission torque capacity while satisfying a point of not reducing the durability of a V belt and not increasing a driving torque of an oil pump. SOLUTION: A sheave surface angleβin an input side pulley 20 in a side determining a pulley ratio is set smaller (β<α) than the sheave surface angleαin an output side pulley 30 in a side determining a pushing force toward the V belt 40.
