The invention belongs to the technical field of power-assisted steering gears, and particularly relates to a self-adaptive automobile electric power-assisted steering gear structure which comprises a steering auxiliary machine shell and a steering rocker arm in transmission connection with a steering shaft of a steering wheel. The outer surface of the middle of the steering straight pull rod is sleeved with a threaded pipe shaft, and a double-position relieving oil cylinder is fixedly arranged on one side of the threaded pipe shaft and located in the open shell. Sealing structures are arranged at the two ends of the threaded pipe shaft correspondingly, an oil leakage prompting structure is arranged on the outer side of the double-position relieving oil cylinder, ball core air valves are assembled at the ends, close to the double-position relieving oil cylinder, of the two oil guide pipes correspondingly, and an anti-overflow valve is fixedly installed at the tail end of an oil supplementing opening through a bolt. An oil supplementing cap is in threaded connection with the end, away from the oil supplementing opening, of the anti-overflow valve. Influences of external force on internal parts can be weakened, a sealing structure facilitating repairing work is provided, the oil leakage condition can be found conveniently, and boosting oil supplementing is facilitated.

    本发明属于助力转向器技术领域,具体涉及一种自适应汽车电动助力转向器结构,包括转向辅助机壳以及与方向盘转向轴传动连接的转向摇臂,所述转向直拉杆中部另一侧的外表面固定安装有液塞一,所述转向直拉杆中部的外表面套设有螺纹管轴,所述螺纹管轴一侧并位于开口壳体的内部固定设置有双位缓解油缸;所述螺纹管轴的两端均设置有密封结构,所述双位缓解油缸的外侧设置有漏油提示结构,两个所述导油管靠近双位缓解油缸的一端均装配有球芯气阀,且补油口的末端通过螺栓固定安装有防溢阀,所述防溢阀远离补油口的一端螺接有补油帽。本发明能够弱化外力对内部零件的影响,具备便捷修缮工作的密封结构,还可便于发现漏油情况、便于助力油补充。
