Transmission device for a mobile machine with turning behaviour control valve

摘要

Each motor (10,20,30,40) is connected to three hydraulic lines and is connected to a hydraulic pump (50). The flow from the pump is divided between the front wheels (51) and the rear wheels and there is a multiple control valve (70) which passes differing proportions of the hydraulic fluid to the four motors to give a differential effect when going round corners.
