Abstract

PURPOSE:To improve operatability by feeding front wheel and rear wheel hydraulic motors with working fluid from separate hydraulic pumps and ensuring that whole working fluid from the pumps is fed to the rear wheel hydraulic motor when a selector valve is changd over. CONSTITUTION:In low-speed operation, an engine 7 is driven and hydraulic pumps 9 and 10 operate so as to discharge working fluid set by a control lever. The working fluid flows through a selector valve 22 into branch valves 11 and 13, where it is divided evenly into right and left portions, then fed to hydraulic motors 3L, 3R, 6L, and 6R for driving front wheels 1L and 1R and rear wheels 2L and 2R at the same speed. For turning, a handle 20 is operated to turn on limit swithches 18 and 19 through the function of a Pitman arm 17 and the solenoid valves 12 and 14 are changed over. Therefore, the high-pressure sides of the motors 3L, 3R, 6L and 6R are shortcircuited, and the left front wheel 1L and left rear wheel 2L rotate rapidly. Result is deflection effect between the left and right motors 3L, 3R, 6L, and 6R and a rapid turning.
