The drive-by-wire type steering device comprises a steering wheel, a fixing shaft is installed at one end of the steering wheel, an automatic rotating mechanism is installed at one end of the center of the fixing shaft, a force feedback assembly is installed at one end of the fixing shaft, and the force feedback assembly is electrically connected with a first ECU through a connecting wire. A steering motor drives a rotating shaft to rotate through transmission of a gear set, then a steering signal is sent to an ECU, then the steering signal is transmitted to a steering mechanism, steering of a steering wheel is achieved through the steering motor, drive-by-wire automatic steering is achieved, and by means of installation of double motors in the automatic rotating mechanism, a main motor and a standby S motor, automatic steering is achieved. The situation of steering failure caused by damage of the main motor is prevented, and the use safety of equipment is improved; a rack in the automatic rotating mechanism is a double-face rack, steering straight gears are meshed with the two faces of the rack, the steering straight gears on the two sides jointly drive the transverse rod to steer, and steering sensitivity can be improved.

    本发明公开了自动驾驶小车线控式转向装置,包括方向盘,所述方向盘一端安装有固定轴,且固定轴中心一端安装有自动转动机构,固定轴一端安装有力反馈组件,且力反馈组件通过连接线电性连接有第一ECU,本法发明转向电机通过齿轮组的传动带动转动轴转动,随即将转向信号发送到ECU,随后传递转向信号给转向机构,利用转向电机实现转向轮的转向,实现了线控式的自动转向,通过自动转动机构中的双电机的安装,一个主电机,一个备用S电机,防止主电机损坏导致的转向失灵的情况出现,提升了设备使用的安全性;自动转动机构中的齿条为双面齿条,两面均啮合有转向直齿轮,两侧的转向直齿轮共同驱动横杆进行转向,有利于提高转向灵敏度。
