Title: Hydraulic control device for continuously variable speed change gear for vehicle
Inventor: YOKOYAMA SHOJI
IPC: F16H9/18
Filed: 1988-11-30
Abstract: PURPOSE:To perform high-efficient transmission of torque by a method wherein an oil pressure responding to the change gear ratio of a V-belt type continuously variable speed change gear, varied through axial movement of a moving flange, is fed to a fluid control circuit to control the hydraulic servo of an output pulley. CONSTITUTION:An oil pressure in an oil pass 3 through which working oil is fed to hydraulic servo 530 and 570 to actuate moving flanges 520B and 560B of output pulleys 520 and 560 is controlled by a change gear ratio detecting valve 50. In this case, since the resilient force of a spring 53 exerted on a valve body 54 of the change gear ratio detecting valve 50 is changed through axial movement of the moving flange 560B, an oil pressure in the oil pass 3 is also changed, and a press force on a V-belt 580 is also changed. With a shaft 550 of the output pulley 560 rotated, the change gear ratio detecting valve 50 is also rotated, but since the valve body 54 is axially movably situated on the axis of a shaft 550, no influence is exercised by a centrifugal force. This constitution enables high-efficient transmission of torque according to a running state.
