The supporting mechanism comprises a steering gear shell, a pressing block is arranged in the steering gear shell, a spring is arranged on the side, opposite to a rack, of the pressing block, the end of the spring is pressed on the pressing block, the supporting mechanism further comprises a lower cover and an upper cover, the upper cover is fixedly arranged, and the upper cover is fixedly connected with the pressing block. The end face, facing the pressing block, of the lower cover is connected with the pressing block in a pressed mode, the end face, back on to the pressing block, of the lower cover is a first end face, the face, facing the lower cover, of the upper cover is a second end face, the first end face and the second end face are completely attached and are both spiral faces, and the spiral directions of the first end face and the second end face are opposite. An elastic piece is arranged between the upper cover and the lower cover, and the elastic force of the elastic piece tends to enable the lower cover to rotate so as to be away from the upper cover. According to the invention, the condition of abnormal sound during automobile running is eliminated, and the condition of impact crushing between the pressing block and the lower cover and between the lower cover and the upper cover is avoided.
本发明涉及一种齿轮齿条转向器的支撑机构、转向器及汽车,包括转向器壳体,所述转向器壳体的内部设有压块,所述压块背向齿条的一侧设有弹簧,弹簧的端部压迫在压块上,还包括下盖和上盖,所述上盖固定布置,所述下盖面向所述压块的端面与所述压块压接,所述下盖背向所述压块的端面为第一端面,所述上盖面向所述下盖的面为第二端面,所述第一端面和第二端面完全贴合,且均为螺旋面,所述第一端面与第二端面的螺旋的方向相反,所述上盖和下盖之间设有弹性件,所述弹性件的弹力具有令所述下盖转动进而远离所述上盖的趋势。本发明消除了汽车行驶时的异响的状况,避免了压块与下盖、下盖与上盖之间的冲击破碎的情况。
