The invention provides a bidirectional balance hydraulic system with a rotation buffering function. The bidirectional balance hydraulic system with the rotation buffering function comprises a two-waybalance valve, a first pilot overflow valve, a second pilot overflow valve, a throttle valve, an OR gate type shuttle valve, a first multi-way valve oil outlet V1, a second multi-way valve oil outletV2, a first motor oil inlet C1, a second motor oil inlet C2, a brake oil port S, an oil tank T, a control pipeline, a first oil return pipeline and a second oil return pipeline. The two-way balance valve comprises a first balance valve and a second balance valve. According to the bidirectional balance hydraulic system with the the rotation buffering function, the two balance valves are integrated,so that the rotation action is stable, sharp abrasion of a brake pad and shaking during stopping caused by direct braking of a reduction gearbox are overcome, the two pilot overflow valves are integrated, a motor rotates after system pressure is established, and the stability of rotation starting is guaranteed; and when stopping is needed, communication of the pressure of the motor oil inlets isachieved through the pilot overflow valves, so that the pressure on the two sides of the motor is balanced, and the problem of shaking stopping caused by pressure impact during stopping is avoided.

    本发明提供一种双向平衡带回旋缓冲液压系统,包括双向平衡阀、第一先导式溢流阀、第二先导式溢流阀、节流阀、或门式梭阀、第一多路阀出油口V1、第二多路阀出油口V2、第一马达进油口C1、第二马达进油口C2、刹车油口S、油箱T、控制管路、第一回油管路和第二回油管路,双向平衡阀包括第一平衡阀、第二平衡阀;本发明通过集成两个平衡阀,使得回转动作平稳,克服由于减速箱直接刹车时造成的刹车片急剧磨损和停止时的抖动,通过集成两个先导式溢流阀,使马达在系统压力建立起之后再转动,保证了回转启动的平稳;当需要停止时,马达进油口压力通过先导式溢流阀连通,使马达两侧压力平衡,避免了停止时压力冲击造成停止抖动的问题。
