Abstract

PURPOSE:To simplify the structure of a controller and reduce the ratio of occurrence of trouble, by controlling a V-belt-type stepless transmission with a throttle cam and a governor valve. CONSTITUTION:A torque ratio control valve 60 has a spool 61 which is located in series with the spool 71 of a throttle valve 71 through a spring 29. load F, which is function of the degree of opening the throttle valve 71, is applied to the left-end land of the torque ratio control valve 60 by the spring 29 to which the movement of a throttle cam 20 is transmitted through the spool 71. Governor pressure Pg is applied to the right-end of the valve 60, which has pressure reception area A. The area of opening of a port 62 connected to an oil passage 1 and that of a drain port 63 are regulated by the equilibration between the spring load F and the governor pressure Pg so that torque ratio pressure PT relating to torque and revolution speed is applied to the hydraulic cylinder 313 of an input-side pulley through an output port 64 and an oil passage 8 to control a V-belt-type stepless transmission perform to stepless speed shifting.
