The invention relates to the technical field of automobile parts, in particular to a frame type auxiliary frame integrated with automobile body part longitudinal beams, which comprises a left longitudinal beam and a right longitudinal beam, a front cross beam and a rear cross beam are fixedly connected between the left longitudinal beam and the right longitudinal beam, and two left automobile body connecting bosses are arranged on one side, far away from the right longitudinal beam, of the left longitudinal beam. Two right vehicle body connecting bosses are arranged on the side, away from the left longitudinal beam, of the right longitudinal beam, a first receding groove is formed in the portion, between the two left vehicle body connecting bosses, of the left longitudinal beam, and a second receding groove is formed in the portion, between the two right vehicle body connecting bosses, of the right longitudinal beam. On the same platform vehicle type, under the condition that various performance targets of a suspension and a vehicle body are met, the lower part parts of the longitudinal beam of the vehicle body are integrated on the auxiliary frame, the weight of aluminum parts can be reduced, the development cost is reduced, the number of final assembly parts is reduced, and the final assembly efficiency is improved.
本发明涉及汽车零部件技术领域,尤其涉及一种集成车身部分纵梁的框架式副车架,包括左纵梁和右纵梁,所述左纵梁与右纵梁之间固定连接有前横梁和后横梁,所述左纵梁远离右纵梁的一侧设置两个左车身连接凸台,所述右纵梁远离左纵梁的一侧设置有两个右车身连接凸台,两个所述左车身连接凸台之间的左纵梁上形成第一避让凹槽,两个所述右车身连接凸台之间的右纵梁上形成第二避让凹槽。本发明在同一平台车型,可在满足悬架及车身各项性能目标情况下,将车身纵梁下部分零件集成到副车架上,能减轻铝制零件重量降低开发成本,减少总装零件数量,提升总装效率。
