Wheel excavator steering control system and control method
The invention discloses a wheel excavator steering control system and method. The system comprises a controller, an electromagnetic reversing valve and a proportional reversing valve. The electromagnetic directional valve and the proportional directional valve are electrically connected to the output end of the controller; the input end of the electromagnetic reversing valve is connected with the main pump through an oil way, and the output end of the electromagnetic reversing valve is connected with the steering gear through an oil way. The main pump drives the walking motor to move, and the walking motor drives a walking mechanism of the wheel excavator to move. The input end of the proportional reversing valve is connected with the gear pump through an oil way, and the output end of the proportional reversing valve is connected with the walking motor and the steering gear through an oil way. When the vehicle is in a high-speed state, the steering flow and the walking flow are reasonably distributed, and the walking energy consumption of the excavator and the risk of turning over due to steering misoperation are reduced.
本发明公开了一种轮式挖掘机转向控制系统及控制方法，系统包括控制器、电磁换向阀和比例换向阀；所述电磁换向阀和比例换向阀电性连接至所述控制器的输出端；所述电磁换向阀的输入端通过油路连接主泵，所述电磁换向阀的输出端通过油路连接转向器；所述主泵驱动行走马达运动，所述行走马达带动所述轮式挖掘机的行走机构运动；所述比例换向阀的输入端通过油路连接齿轮泵，所述比例换向阀的输出端通过油路连接行走马达和转向器；本发明在车辆处于高速状态下，合理分配转向流量和行走流量，降低挖掘机的行走能耗以及转向误操作翻车的风险。
