The invention discloses a multidirectional forklift hydraulic system based on a hydraulic motor. The multidirectional forklift hydraulic system comprises a driving wheel, wherein the driving wheel is disposed in the middle of the rear portion of a vehicle body, and the driving wheel is connected with a driving wheel steering motor through a first transmission device; a left bearing wheel, wherein the left bearing wheel is disposed on a left supporting leg of the vehicle body, and the left bearing wheel is connected with a left bearing wheel steering motor through a second transmission device; and a right bearing wheel, wherein the right bearing wheel is arranged on a right supporting leg of the vehicle body and connected with a right bearing wheel steering motor through a third transmission device. Traveling wheels are connected with a hydraulic motor, so that direct use of an oil cylinder for driving is avoided, and the mounting space is greatly reduced; meanwhile, an electromagnetic valve and an electromagnetic proportional valve in the whole-vehicle hydraulic system are combined for use, so that the whole-vehicle hydraulic system is quick in steering response, quick in action and low in comprehensive cost; and in addition, the hydraulic motor is high in overload resistance, the failure rate of the whole vehicle is reduced, and maintenance is relatively convenient.
本发明公开了一种基于液压马达的多向叉车液压系统,包括驱动轮,其居中的设置在车身后部,所述驱动轮通过第一传动装置与驱动轮转向马达连接,左承载轮,其设置在车身左支腿上,所述左承载轮通过第二传动装置与左承载轮转向马达连接,右承载轮,其设置在车身右支腿上,所述右承载轮通过第三传动装置与右承载轮转向马达连接。本发明通过将各个行驶轮连接液压马达,避免了直接使用油缸驱动,极大的降低安装空间;同时整车液压系统中电磁阀和电磁比例阀组合使用,使整车液压系统转向响应快,动作迅速和综合成本低;另外液压马达抗过载能力强,降低了整车的故障率,维护也较为方便。
