一种配砟整形车四轴驱动结构
摘要：
本发明公开了一种配砟整形车四轴驱动结构，包括发动机、分动箱、油泵、液压驱动马达、齿轮箱和轮对，发动机传动连接于分动箱，分动箱传动连接于油泵；油泵包括两个，液压驱动马达包括四个，分动箱驱动连接两个油泵；一个油泵分别连接两个液压驱动马达，该两个液压驱动马达分别连接于两个齿轮箱，该两个齿轮箱分别连接于配砟整形车的前转向架和后转向架的一轮对；另一个油泵分别连接于另外两个液压驱动马达，该两个液压驱动马达分别传动连接于两个齿轮箱，该两个齿轮箱分别连接于配砟整形车的前转向架和后转向架的另一轮对。本发明可大幅度提高了整车的牵引能力，并且在牵引力需求较小时，可以实现一个油泵带动两个驱动马达的液压传动形式。
摘要（英）：

The invention discloses a four-axis driving structure of a ballast distributing and regulating vehicle. The structure comprises an engine, a transfer case, two oil pumps, four hydraulic driving motors, gear boxes and wheel pairs, the engine is in transmission connection with the transfer case, the transfer case is in transmission connection with the oil pumps, and the transfer case is in driving connection with the two oil pumps; one oil pump is connected with two hydraulic driving motors separately, wherein the two hydraulic driving motors are connected with the two gear boxes respectively, and the two gear boxes are connected with one wheel pair of a front bogie and a rear bogie of the ballast distributing and regulating vehicle respectively; the other oil pump is connected with the other two hydraulic driving motors separately, wherein the two hydraulic driving motors are in communication with the other two gear boxes respectively, and the two gear boxes are connected with the otherwheel pair of the front bogie and the rear bogie of the ballast distributing and regulating vehicle respectively. By means of the four-axis driving structure of the ballast distributing and regulating vehicle, the traction capability of the whole vehicle can be greatly improved, and the hydraulic transmission mode of driving every two driving motors by one oil pump can be achieved when the traction demand is low.
