The embodiment of the invention provides a steering device of a drive-by-wire steering wheel and a steering limiting mechanism. A steering column of the steering device is connected to the steering limiting mechanism and can drive the steering limiting mechanism to rotate. The steering limiting mechanism comprises a base, a driving piece and a driven piece, wherein a linear track and a spiral track which correspond to each other are arranged between the base and the driving piece. The driven piece is arranged between the linear track and the spiral track and can be guided by the spiral track to move in the linear track in a reciprocating mode. When the driven piece moves to the head end or the tail end of the linear rail, the steering column can be stopped from rotating continuously, so that the drive-by-wire steering wheel stops rotating, and the problem that a driver cannot judge whether the drive-by-wire steering wheel is recovered to the neutral position or not due to excessive rotation of the drive-by-wire steering wheel is avoided.

    本申请实施例提供一种线控方向盘的转向装置和转向限位机构。转向装置的转向柱连接于转向限位机构,并且可以带动转向限位机构转动。转向限位机构包括底座、主动件和从动件,其中底座和主动件之间设置有相对应的线性轨道和螺旋轨道。从动件设置在线性轨道和螺旋轨道之间,并且可以受到螺旋轨道的导引,在线性轨道内往复位移。当从动件位移至线性轨道的头端或尾端时,可以止挡转向柱继续转动,从而使线控方向盘停止转动,避免因线控方向盘过度转动导致驾驶员无法判断其是否恢复至中位的问题发生。
