Abstract: PURPOSE: A hydraulic controlling system of a CVT(continuously variable transmission) is provided to drive a vehicle in specific transmission/torque ratios by controlling the transmission ratio to an intermediate value between the maximum points and minimum points value in a fail of a TCU(transmission control unit). CONSTITUTION: In a fail of a TCU, a solenoid valve(S) is turned off and a valve spool(45) of a fail-safe valve(7) moves to left. A transmission ratio controlling valve(5) feeds hydraulic pressure to a driving pulley(11) through a first port(29) of the fail-safe valve(7) to fix a transmission ratio. A manual valve(3) supplies line pressure to a reverse brake(25) normally through fourth to sixth ports(35,37,39). Thus, a vehicle is backed up.

Abstract: PURPOSE: A transmission ratio controlling system of a CVT(continuously variable transmission) is provided to simplify a circuit of a TCU(transmission control unit) and to predict a fail as well as to reduce a manufacturing cost. CONSTITUTION: During driving, an input torque and line pressure are reduced by decreasing in the opening degree of a throttle valve. A driven pulley decreases in diameter and a belt penetrates into the driven pulley. The belt loses tension and a moving sheave(13) of a driving pulley(1) moves to left. The driving pulley(1) increases in diameter and the belt comes out of the pulley(1). A link(9) rotates clockwise and allows an adaptor(7) to move to right. A transmission ratio control valve(5) moves to right and a part of hydraulic pressure is discharged from the driving pulley(1). Thus, the moving sheave(13) moves to right and the driving pulley(1) decreases in diameter to control a CVT to the original transmission ratio.
