The invention provides an integrated valve block, a hydraulic braking system and an electric forklift hydraulic braking method.The hydraulic integrated valve block comprises a valve body, and an oil inlet P0, an oil return port and a detection oil port M connected with a pressure sensor are formed in the valve body; an OPS electromagnetic valve is connected between the oil inlet P0 and the pilot oil port P1, an unloading valve is connected between the oil inlet P0 and the energy storage oil port P2, a logic valve is connected between the oil inlet P0 and the cooling oil port D, and the unloading valve is connected with the logic valve through an oil way. The oil inlet end of the brake oil port P3 is connected with the energy storage oil port P2 through a two-position three-way electromagnetic valve. Control oil ways of a service brake, a parking brake, a drive axle, an OPS function and the like are integrated into the integrated valve block and are connected and controlled through oil ports respectively. The hydraulic system is easy to install, compact in structure and convenient to install and maintain, and cost is reduced.
本发明提供一种集成阀块、液压制动系统及电动叉车液压制动方法,其中液压集成阀块,包括阀体,所述阀体上设有进油口P0、回油口以及与压力传感器连接的检测油口M;所述进油口P0与先导油口P1之间连接有OPS电磁阀,所述进油口P0与蓄能油口P2之间连接有卸荷阀,所述进油口P0与冷却油口D之间连接有逻辑阀,所述卸荷阀与逻辑阀之间通过油路连接;所述制动油口P3的进油端通过两位三通电磁阀与蓄能油口P2连接。本发明将行车制动器、停车制动器、驱动桥、OPS功能等控制油路集成到本集成阀块,分别通过油口进行连接控制。使液压系统安装简单,结构紧凑便于安装保养,还降低了成本。
