The invention discloses an auxiliary frame structure for a car chassis. The auxiliary frame structure comprises a front tubular beam and a rear tubular beam, the front tubular beam and the rear tubular beam are connected through a car body support, connecting supports are connected to the left ends and the right ends of the front tubular beam and the rear tubular beam, each connecting support is composed of an upper support body and a lower support body, and the outer ends of the connecting supports are connected with lining installation bases. And vehicle body bushings are mounted on the lining installation bases. The connecting supports are formed by tailor-welding the upper support bodies and the lower support bodies, so that the single-piece cost of a rear auxiliary frame is reduced, and the manufacturing defects caused by difficult forming are reduced.
本发明提供一种用于轿车底盘副车架结构,包括前管梁和后管梁,前管梁和后管梁之间通过车身支架连接,前管梁和后管梁左右两端连接有连接支架,连接支架由支架上体和支架下体组成,连接支架外端连接有衬套安装座,衬套安装座上安装有车身衬套。采用支架上体和支架下体两个冲压件拼焊来组成连接支架,降低了后副车架的单件成本,降低了由于成型难而造成的制造缺陷。
