The hydraulic power take-off system comprises a wheel side motor support, a power take-off device support and a hydraulic pump, and the wheel side motor support is provided with a wheel side motor; the power take-off device support is provided with a power take-off device, the power take-off device is connected with a wheel edge motor through a transmission shaft, the power take-off device is provided with a wheel output port and a power take-off output port, and the power take-off device is provided with a pneumatic gear shifting mechanism. The hydraulic pump is connected to the power take-off output port, and the pneumatic gear shifting mechanism is used for controlling the power take-off device to transmit output power of the wheel edge motor to the wheel output port or the power take-off output port. The wheel output port and the power take-off output port are formed in the power take-off device, and the hydraulic pump is connected to the power take-off output port, so that the output power of the wheel-side motor can be transmitted to the wheels through the power take-off device and can also be transmitted to the hydraulic pump through the power take-off device through the pneumatic gear shifting mechanism; the technical problems that in the prior art, a hydraulic system usually adopts an independent matched high-power motor, the whole vehicle cost is increased, and the vehicle reliability is reduced are solved.
本申请涉及一种液压取力系统,其包括:轮边电机支架、取力装置支架和液压泵,轮边电机支架安装有轮边电机;取力装置支架安装有取力装置,取力装置通过传动轴与轮边电机连接,取力装置具有车轮输出口和取力输出口,且取力装置安装有气动换挡机构;液压泵连接至取力输出口,气动换挡机构用于控制取力装置将轮边电机的输出动力传递至车轮输出口或者取力输出口。通过在取力装置上设置车轮输出口和取力输出口,并将液压泵连接至取力输出口,轮边电机的输出动力不仅能够通过取力装置传递至车轮,还能通过气动换挡机构换成通过取力装置传递至液压泵,解决了相关技术中液压系统通常采用单独配套大功率电机,增加整车成本,降低车辆可靠性的技术问题。
