The invention discloses an electric steering mechanism with a wear self-repairing function. The electric steering mechanism comprises a driving motor, a planetary roller screw, a sector gear and an output shaft; an output shaft of the driving motor is connected with the planetary roller lead screw, the planetary roller lead screw is connected with the sector gear, and the sector gear is installedon the output shaft. Due to the fact that a hydraulic system is omitted, the working efficiency is high, noise pollution is small, and the phenomena of air leakage and liquid leakage do not exist. Especially for various new energy vehicles, as the power source of the device does not depend on an engine and automatic control is easy to realize, the electric steering mechanism has a wider application prospect compared with the traditional structure. By adopting the planetary roller mechanism and the lubricating grease with the self-repairing function, the complexity of the steering mechanism issimplified, the boundary dimension of the mechanism is reduced, and the service life of the mechanism can be prolonged.

    一种具有磨损自修复功能的电动转向机构,包括驱动电机、行星滚柱丝杠、扇形齿轮和输出轴。驱动电机的输出轴与行星滚柱丝杠相连,行星滚柱丝杠与扇形齿轮相连,扇形齿轮安装在输出轴上。本发明由于取消了液压系统,所以其工作效率高,噪音污染小,不存在漏气、漏液现象。特别在各种新能源车上,由于其动力源不依赖发动机,且易于实现自动控制,所以较传统结构有着更广的应用前景。采用行星滚柱机构和具有自修复功能的润滑脂,不但简化了转向机构的复杂程度,缩小机构外形尺寸,而且可延长机构寿命。
