Power distribution system for loader, power distribution method for loader, and loader
The invention belongs to the technical field of loaders, and discloses a power distribution system of a loader, a power distribution method of the loader and the loader.In the power distribution system of the loader, a walking pump is in transmission connection with a walking device, a first electric proportional pressure reducing valve is used for adjusting the output displacement of the walking pump, and a working pump is in transmission connection with a working device; the second electric proportional pressure reducing valve is used for adjusting the constant power adjustment starting point pressure value of the working pump, the walking pump and the working pump are both in transmission connection with the engine, the first stroke sensor is used for detecting the stroke of an accelerator pedal, and the second stroke sensor is used for detecting the stroke of an intelligent brake pedal. The first stroke sensor, the second stroke sensor, the first electric proportional pressure reducing valve and the second electric proportional pressure reducing valve are all electrically connected with the controller. According to the power distribution system of the loading machine, stepless adjustment of the vehicle speed can be achieved, the running speed of the vehicle can be controlled at the centimeter level, and power waste and early damage of parts under the limiting working condition can be prevented.
本发明属于装载机技术领域，公开了装载机的功率分配系统、装载机的功率分配方法及装载机，该装载机的功率分配系统中，行走泵与行走装置传动连接，第一电比例减压阀用于调节行走泵的输出排量，工作泵与工作装置传动连接，第二电比例减压阀用于调节工作泵的恒功率起调点压力值，行走泵和工作泵均与发动机传动连接，第一行程传感器用于检测油门踏板的行程，第二行程传感器用于检测智能制动踏板的行程，第一行程传感器、第二行程传感器、第一电比例减压阀和第二电比例减压阀均与控制器电连接。该装载机的功率分配系统，能够实现车速无极可调，车辆的行驶速度可以厘米级别控制，而且能防止极限工况下产生功率浪费和零部件提早损坏。
