The invention relates to a loader wheel side hydraulic motor four-wheel-drive system which is characterized in that a PA port of a plunger pump is connected with an A port of a flow dividing module, an A1 port of the flow dividing module is connected with an A port of a left rear motor, and an A2 port of the flow dividing module is connected with an A port of a right rear motor; a port R of the left rear motor is connected with a port A of the left front motor through a first pipeline, and a port R of the left front motor is connected with a port PB of the plunger pump; a port R of the right rear motor is connected with a port A of the right front motor through a second pipeline, and a port R of the right front motor is connected with a port PB of the plunger pump; a first electromagnetic directional valve and a throttle valve are connected between the first pipeline and the second pipeline; the first electromagnetic directional valve is in a normally open state, and the throttling valve is arranged beside the first electromagnetic directional valve, so that oil of the two front wheel motors can be finely adjusted during steering, namely part of hydraulic oil can flow to the second pipeline through the first pipeline or flow to the first pipeline through the second pipeline, and accelerated abrasion of tires is avoided.

    本发明是一种装载机轮边液压马达四驱系统,柱塞泵的PA口与分流模组的A口连接,分流模组的A1口与左后马达的A口连接,分流模组的A2口与右后马达的A口连接;左后马达的R口与左前马达的A口通过第一管路连接,左前马达的R口与柱塞泵的PB口连接;右后马达的R口与右前马达的A口通过第二管路连接连接,右前马达的R口与柱塞泵的PB口连接;第一管路、第二管路之间连接有第一电磁换向阀、节流阀;第一电磁换向阀处于常通状态,第一电磁换向阀旁有一节流阀,能使两前轮马达的油液在转向时进行微量调节,即有部分液压油可经第一管路流至第二管路,或第二管路流至第一管路,避免轮胎加速磨损。
