Abstract

PURPOSE: To plan to reduce an effort for driving and to enable to utilize a pressure energy from a pressure source without wasting by enabling to effect steering operations of a vehicle by steering only one steering-rod controlling clutches and brakes for left and right caterpillars.
CONSTITUTION: A pump 10 for clutches and a pump 11 for brakes, which is also operating transmission, are provided, and pressurized oil from the pump 10 is selectively supplied to left or right clutches 3L, 3R through a steering valve 33. A working machine back up valve 20, supplying discharged oil of the pump 10 to the circuit of the working machine under cooperating with the valve 33 while steering operations are not effected, is interposed at the upper stream of the steering valve 33. Brake valves 31L, 31R, selectively operating left or right brakes by connecting or disconnecting the supply of the pressurized oil from the pump 11 in responding to pressure variations upon releasing respective clutches 3L, 3R, are provided, while a torque convertor 25 is connected to the pump 11 through a relief valve 27.
