The invention relates to an automobile chassis part, and in particular relates to an aluminum alloy auxiliary frame. The aluminum alloy auxiliary frame comprises a front cross beam, a rear cross beam parallel to the front cross beam, upper beams arranged at the two ends of the front cross beam respectively, and lower beams parallel to each other and connected with the two upper beams and the two ends of the rear cross beam respectively. The upper beams are formed by low pressure casting, the front cross beam, the rear cross beam and the lower beams are formed through extrusion, the front cross beam, the rear cross beam, the upper beams and the lower beams are connected through welding, two sets of parallel front cross beam supports are welded to the upper side of the front cross beam, rear cross beam sleeves are welded to the two ends of the rear cross beam, longitudinal beam supports are welded to the outward sides of the lower beams, and the front cross beam supports, the rear cross beam sleeves and the longitudinal beam supports are used for fixedly mounting the frame. According to the technical scheme, the technical problem of how to meet the requirements of strength and rigidity of the auxiliary frame while reducing the overall weight of the frame is solved.
本发明涉及一种汽车底盘零部件,具体是涉及一种铝合金副车架,前横梁,以及平行于前横梁设置的后横梁,以及分别设置在前横梁两端的上梁,以及彼此平行并且分别连接两个上梁与后横梁两端的下梁,上梁通过低压铸造成型,前横梁、后横梁和下梁通过挤压成型,前横梁、后横梁、上梁和下梁之间通过焊接连接,前横梁的上侧焊接安装有两组平行的前横梁支架,后横梁的两端焊接安装有后横梁套筒,下梁朝外的一侧焊接安装有纵梁支架,所述前横梁支架、后横梁套筒和纵梁支架用于车架的固定安装,本技术方案解决了如何在降低车架整体重量的同时满足副车架的强度与刚度的需求的技术问题。
