The utility model relates to a steering mechanism and with this steering mechanism's vehicle, the same first turn to the subassembly to steering mechanism and the second turns to the subassembly including turning to, still include to turn to the first connecting piece of subassembly articulated and turn to subassembly articulated second connecting piece with the second with first, steering mechanism still includes the rotating member that links together first connecting piece and second connecting piece, the rotating member is articulated with first connecting piece and second connecting piecerespectively, the first subassembly that turns to the subassembly transmission through first, second connecting piece and rotating member with the second and is connected. Fall into first connectingpiece and second connecting piece to the connecting piece, and set up the rotating member between first connecting piece and second connecting piece, reduced the length of connecting piece, make the connecting piece reduce the atress in the course of the work, increased the life -span of connecting piece, and adopted the rotating member at middle part, can realize turning than the automobile bodyof small diameter within range.
