Wheel bulldozer fine motion function and hydraulic braking control system

The utility model discloses a wheel bulldozer fine motion function and hydraulic braking control system belongs to the wheel bulldozer field. The utility model discloses an oil tank, inhale oil filter, gear pump, high pressure filter, prefill valve, fine motion hydro -cylinder, left pedal valve, pressure switch, braking valves, right pedal valve, shuttle valve valves, rear axle stopper, front axle stopper, parking brake. The utility model discloses a setting of left pedal valve (fine motion function treadle valve) for the driver combines tire drive power effective control tire drive power between 0% to 100%, prevents the wheel -slip, reduces the tire wear, but like this effective use engine power, reduce oil consumption, quickening circulation velocity. The fine motion function can also realize emergency braking through the service brake ware in effective control tire drive power, showing increase braking system reliability and driving safety. The tube coupling has been simplified greatly to this control system's main element integration on the braking valves, make the pipeline layout more equitable.
