ABSTRACT:
A pulley thrust pressure control apparatus for a belt-type continuously variable transmission having a drive pulley connected with an input member, a driven pulley connected with an output member, a V-belt trained around the drive and driven pulleys, a drive cylinder for varying the pulley width of the drive pulley, and a driven cylinder for varying the pulley width of the driven pulley. The actual transmitting torque transmitted through the V-belt is calculated and a belt transmittable torque is calculated by multiplying the actual transmitting torque by a safety factor which is higher when said actual transmitting torque is negative than when it is positive. A pulley thrust pressure control valve controls the pressures supplied to the drive and driven cylinders so as to obtain the calculated belt transmitting torque.
