The invention discloses a lightweight upper guide beam in a trailer air suspension system, which comprises an upper cover plate, an upper swing arm, a baffle plate, a sleeve and a bushing, the bushingis pressed in the middle of the sleeve, the upper surface of the sleeve is welded and fixed at the front end of the upper swing arm, and the lower surface of the sleeve is welded and fixed at the front end of the baffle plate; the upper swing arm is welded to the upper surface of the baffle plate along the lower surface; the rear end of the upper swing arm is welded to the upper surface of the upper cover plate; the light-weight upper guide beam in the trailer air suspension system replaces the front half part of a plate spring in a traditional trailer suspension, the structure is simplified,the design concept of a box body is adopted, the torsion resistance of the upper guide beam is improved. The service life of the upper guide beam is effectively prolonged, and the production cost andthe maintenance cost are reduced.
本发明公开了一种挂车空气悬架系统中轻量化的上导向梁,包括上盖板,上摆臂,挡板,套管,衬套,所述衬套居中压装在套管中,所述套管的上面焊接固定在上摆臂前端,所述套管的下面焊接固定在挡板前端,所述上摆臂沿下面焊接在挡板的上面,所述上摆臂后端焊接在上盖板的上面,该挂车空气悬架系统中轻量化的上导向梁,代替传统挂车悬架中的板簧前半部分,结构简化,采用盒体的设计理念,提高上导向梁的抗扭能力,有效提高上导向梁的使用寿命,降低生产成本以及维修成本。
