Gear shifting system and method of wheel excavator
The gear shifting system comprises a transfer connector, a hydraulic motor A, a gear shifting control valve, a reduction gearbox and a hydraulic motor B. The transfer connector is connected with the gear shifting control valve, the gear shifting control valve is connected with the hydraulic motor A and the hydraulic motor B, and the hydraulic motor A and the hydraulic motor B are connected with the reduction gearbox. And the reduction gearbox is arranged on the frame. According to the system, gear shifting operation of the vehicle at any vehicle speed can be achieved, the hydraulic motor does not have the overspeed phenomenon in the gear shifting process, the comfort of a driver and the reliability of the hydraulic motor are improved, high-speed running can be continuously conducted, the working efficiency is improved, the hydraulic motor can be effectively protected through the balance valve, and the service life of the vehicle is prolonged. And the phenomenon of slope sliding can be prevented, and the safety of the whole vehicle is improved.
本发明公开了轮式挖掘机换挡系统及方法，所述换挡系统包括中转接头、液压马达A、换挡控制阀、减速箱、液压马达B，所述中转接头与换挡控制阀连接，所述换挡控制阀分别与液压马达A、液压马达B连接，所述液压马达A、液压马达B分别与减速箱连接，所述减速箱设置车架上。本发明的系统能实现车辆在任意车速下进行换挡操作，液压马达在换挡过程中且不会出现超速现象，提高了驾驶人员的舒适性和液压马达的可靠性，可持续进行高速行驶，提高了工作效率，平衡阀可有效的保护了液压马达，可防止出现溜坡现象，提高了整车的安全性。
