The invention relates to the technical field of engineering machinery, discloses a brake heat dissipation control system and engineering machinery, and discloses an efficient brake heat dissipation control system which comprises a brake variable pump, a liquid filling control valve set, an energy accumulator, a heat dissipater, a brake disc, a brake pedal, a return oil filter and a hydraulic oil tank. The liquid filling control valve group is used for ensuring that liquid is filled preferentially when the pressure of the energy accumulator is lower than the set pressure, the liquid filling process is stable, the liquid filling pressure accords with a liquid filling control set value, and the situation that the pressure of the energy accumulator is higher than that of the liquid filling control valve when the pump opening load of the brake variable pump is higher than the highest set pressure of the liquid filling control valve is avoided. Load sensitive control can be achieved when the radiator works independently, the outlet pressure of the brake variable pump is adjusted according to the liquid filling load during liquid filling work, constant-flow liquid filling is achieved, in the pressure maintaining state of the energy accumulator, the pressure behind the liquid filling control valve is not affected by the outlet pressure of the brake variable pump, and the stability of a brake system is guaranteed when a vehicle rotates at different rotating speeds.

    本发明涉及工程机械技术领域,公开了一种制动散热控制系统及工程机械,本发明公开一种高效的制动散热控制系统,包括制动变量泵、充液控制阀组、蓄能器、散热器、制动盘、制动踏板、回油过滤器以及液压油箱,充液控制阀组用于保证蓄能器压力低于设定压力时优先充液,保证充液过程平稳,充液压力符合充液控制设定值,避免出现制动变量泵的泵口负载高于充液控制阀最高设定压力时,蓄能器压力高于充液控制阀的情况。本发明可以实现散热器单独工作时负载敏感控制、充液工作时根据充液负载调节制动变量泵出口压力,恒流充液,在蓄能器保压状态下,充液控制阀后的压力不受制动变量泵出口压力影响,保证车辆在不同转速时制动系统的稳定性。
