Abstract
PURPOSE:To improve the transmission efficiency and dissolve faulty return to low speed gear by regulating the oil pressure in a load thrust controlling oil chamber to the optimum oil pressure according to the torque generated at an engine and compensating the optimum oil pressure using the time variation ratio of car speed. CONSTITUTION:In a V-belt type stepless speed change gear a load thrust controlling oil chamber 17 and a transmission ratio controlling oil chamber 16 are formed at a driving pulley and a driving pulley, respectively. In such case according to both throttle opening position and engine r.p.m. a means 81 calculates the torque to be transmitted to the driven pulley and determines the optimum oil pressure in the load thrust controlling oil chamber 17 suitable for said torque. Furthermore, a differentiation means 82 calculates the time change ratio of car speed. And a means 83 multiplies the time change ratio of car speed by a coefficient and determines the compensative oil pressure of the load thrust controlling oil chamber 17.
