Travelling system for hybrid power static pressure bulldozer
The invention relates to the technical field of engineering machinery static pressure bulldozers, in particular to a travelling system for a hybrid power static pressure bulldozer. The travelling system involves a power part, a main pipeline, an execution output part, an air suction preventing assembly, a flushing valve and an overload preventing valve, wherein the output end of the power part is connected with a variable pump-motor, high-pressure oil in a main pipeline connected with the high-pressure oil output end of the variable pump-motor is divided into a plurality of branches, the execution output part, the air suction preventing assembly, the flushing valve and the overload preventing valve are all installed on the corresponding branches, and the tail ends of the branches are connected back to the low-pressure oil end of the main pipeline. A permanent magnet synchronous motor and a travelling variable are coaxially connected with an engine through a clutch, the clutch is disconnected when the output power is not high in the working state, and the motor is directly driven by a battery to rotate, so that the travelling or bulldozing action is achieved, and when high-power output is needed, the engine works, and at the moment, the motor is converted into a power generator to charge the battery, so that energy conservation and energy recovery are achieved in a real sense.
本发明涉及工程机械静压推土机技术领域，尤其是一种混合动力静压推土机行走系统，包括动力部件、主管路、执行输出部件、防吸空组件、冲洗阀、防过载阀，所述动力部件的输出端与变量泵‑马达相连接，与所述变量泵‑马达的高压油输出端相连的主管路内的高压油分为若干支路，执行输出部件、防吸空组件、冲洗阀、防过载阀均安装在对应的各支路上，各所述支路的末端接回主管路的低压油端。永磁式同步电机与行走变量经过离合器同轴与发动机连接，在工作状态输出功率不高时离合器断开，直接由电池带动电机转动，实现走车或者推土动作，当需要大功率输出时，发动机工作，这时电机转为发电机给电池充电，真正意义的实现节能和能量回收。
