The invention relates to a supporting bush for a steering gear rack, and belongs to the technical field of automobile steering systems, the supporting bush comprises a steering gear shell and a rack body accommodated in the steering gear shell, a blocking piece and a bush body are sequentially clamped in the steering gear shell in the transverse direction, and the adjacent ends of the blocking piece and the bush body are in close contact. The rack body penetrates through the blocking piece to be connected with the bushing body, the bushing body comprises an injection molding layer, a steel bushing layer and a rubber layer which are sequentially arranged from inside to outside, and the rubber layer is in close contact with the inner wall of a steering gear shell. The problem that when the steering gear is impacted by a large load and the rack swings up and down, the supporting bush collides with the steering gear shell to generate abnormal sound can be solved, and the problem that the supporting bush axially moves and collides with the steering gear shell to generate abnormal sound during rapid left-right reversing can also be solved.
本发明涉及一种转向器齿条用的支撑衬套,属于汽车转向系统技术领域,包括转向器壳体、容置在转向器壳体内的齿条本体,所述转向器壳体内沿横向依次卡设有阻挡件、衬套本体,所述阻挡件与衬套本体的相邻端紧密接触,所述齿条本体穿过阻挡件与衬套本体连接,所述衬套本体包括从里到外依次设置的注塑层、钢套层、橡胶层,所述橡胶层与转向器壳体内壁紧密接触。本发明不仅能解决转向器在受到较大载荷冲击齿条上下摆动时,支撑衬套与转向器壳体碰撞产生异响的问题,还能解决快速左右换向时支撑衬套轴向窜动与转向器壳体碰撞产生异响的问题。
