VEHICLE DRIVE AND SPEED COMBINATION CONTROL DEVICE

摘要

FIELD: transport engineering. SUBSTANCE: proposed device has source of working medium, servocylinder or disengagement chamber, preliminary pressure drop valve and clutch engagement rate regulator. All these members are connected through control valve box provided with intake and outlet valves. valve box housing accommodates accelerating piston rigidly coupled with intake valve shutoff member. Seat of outlet valve is provided with pressure acting spring. Axial and radial holes are made in seat through which working spaces of servocylinder (chambers), preliminary pressure drop valve, clutch engagement rate regulator and accelerating piston cylinder are communicated. Outlet valve seat is connected with movable plate of return spring of gear shift lever movable handle. EFFECT: unification of device for combination control of vehicle drive and clutch with provision of high reliability. 1 dwg
