Hydrostatic drive multifunctional snow sweeper
The invention relates to the technical field of snow sweepers, in particular to a hydrostatic drive multifunctional snow sweeper. The system comprises a closed variable plunger pump, the output end of the closed variable plunger pump is connected with a control system, the two ends of the control system are connected with a front wheel hydraulic motor and a rear wheel hydraulic motor in parallel, the front wheel hydraulic motor and the rear wheel hydraulic motor are connected with an oil tank, and the control system is connected with a servo system. A one-pump two-motor closed hydrostatic driving system is adopted, a pump is connected with an engine, the hydraulic motors are connected with steering drive axles, hydraulic oil reaches the motors through the pump and then acts on the axles, and therefore the functions of advancing, retreating, steering and the like of the sweeper are achieved; due to the fact that no transmission shaft component exists, a space below the position from a main shaft to a middle frame can be completely used for rolling brushes, and the modification amount is reduced; and the servo system is adopted, the response speed is high, work is stable, the anti-jamming capability is high, and energy conservation and high efficiency are achieved.
本发明涉及除雪车技术领域，具体为一种静液压驱动多功能除雪车。包括闭式变量柱塞泵，闭式变量柱塞泵输出端连接有控制系统，控制系统两端并联有前轮液压马达和后轮液压马达，前轮液压马达和后轮液压马达均连接油箱，控制系统连接有伺服系统。采用一泵两马达的闭式静液压驱动系统，泵与发动机相连，液压马达与转向驱动桥相连，液压油通过泵到马达再作用于桥上，从而实现车辆前进后退转向等功能，并且因无传动轴部件，主轴距中间车架以下空间全部可供滚刷使用，减少改动量；采用伺服系统，响应速度快，工作稳定，抗干扰能力强，节能高效。
