The invention relates to a lead screw nut and steering pull rod integrated electric steering device comprising a driving motor, a planetary roller lead screw, a hinge and a steering longitudinal pullrod. And a speed reducer is arranged in the driving motor. And an output shaft of the driving motor is connected with the planetary roller lead screw. And the planetary roller lead screw is connectedwith the steering longitudinal pull rod through the hinge. Since 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 does not depend on an engine and automatic control is easy to realize, the integrated electric steering device has awider application range by being compared with the traditional structure; the planetary roller mechanism with the self-repairing function is adopted, the complexity of the steering mechanism can be simplified, the boundary dimension of the mechanism is reduced, and the service life is prolonged.
一种丝杆螺母与转向拉杆一体式电动转向装置,包括驱动电机、行星滚柱丝杠、铰链和转向纵拉杆。所述驱动电机内部设置有减速器。所述驱动电机的输出轴与行星滚柱丝杠相连。所述行星滚柱丝杠通过铰链与转向纵拉杆相连。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范围;采用具有自修复功能的行星滚柱机构,可简化转向机构复杂程度,缩小机构外形尺寸,延长使用寿命。
