The invention discloses a multi-safety-guarantee anti-explosion pure electric SUV full-hydraulic braking system which mainly comprises a double pump, an oil tank, an oil filter, a double-loop prefill valve, an energy accumulator, a double-loop foot valve, a handle valve, a front wheel wet brake and a rear wheel wet brake. The full-hydraulic braking system further comprises a two-position three-way ball valve, the two-position three-way ball valve is located between an SW opening of the double-loop prefill valve and an oil inlet of the handle valve, and the other opening of the two-position three-way ball valve is connected with an oil pumping loop in parallel to be connected with an oil tank. A two-position three-way ball valve is further connected in the parking oil way in series and used for being connected with a manual oil pumping loop in parallel, and the hand brake releasing mode is changed by switching the oil way of the ball valve. The system is clear in principle, high in safety and capable of being effectively suitable for the design of a braking system of the mining underground command vehicle, and compared with an existing market braking principle, a plurality of failure safety guarantee measures are added, so that the braking safety of the vehicle under the mine can be effectively guaranteed.

    本发明公开了一种多安全保障的防爆纯电动SUV全液压制动系统,主要包括双联泵、油箱、油滤器、双回路充液阀、蓄能器、双回路脚阀、手柄阀、以及前轮湿式制动器和后轮湿式制动器;所述全液压制动系统还包括二位三通球阀,所述二位三通球阀位于所述双回路充液阀的SW口与手柄阀的进油口之间,所述二位三通球阀的另一个口上并联一条泵油回路连接油箱。在驻车油路中还串联一个二位三通球阀用于并联一条手动泵油回路,通过切换球阀的油路改变解除手刹方式。本发明原理清晰,安全型高,能够有效适用于矿用井下指挥车辆的制动系统设计,其相比于现市场制动的原理,增加多个失效安全保障措施,能够使车辆矿下的制动安全得到有效的保证。
