The novel stamping and welding front auxiliary frame comprises an auxiliary frame body, the auxiliary frame body is composed of a left longitudinal beam, a right longitudinal beam, a front cross beam and a rear cross beam, front anti-collision beam supports are welded to the left end and the right end of the surface of the front cross beam, the left longitudinal beam and the right longitudinal beam are installed on the left side and the right side of the auxiliary frame body, and the rear cross beam is installed on the left side and the right side of the auxiliary frame body; a stress groove is formed in the surface of the middle tower sleeve, a swing arm front point support is installed on the front side face of the middle tower sleeve, and front anti-collision beam supports are welded to the front end of the left longitudinal beam and the front end of the right longitudinal beam correspondingly. According to the novel stamping and welding front auxiliary frame, the left longitudinal beam and the right longitudinal beam are stamping parts, the front cross beam is formed by combining a stamping pipe beam and a welding beam, the size precision of the overall molded surface of the auxiliary frame is improved, the front cross beam is formed by assembling pipe fittings and welding parts, arrangement is compact, the requirement for arrangement space is reduced, and through the design of the local lap joint molded surface and the structure, the overall size precision of the auxiliary frame is improved. The matching lap joint precision between parts is improved, and the overall durability and rigidity of the auxiliary frame are improved.

    本发明公开了一种新型冲压焊接前副车架,包括副车架本体,其由左纵梁、右纵梁、前横梁和后横梁组成,所述前横梁表面的左右两端焊接有前防撞梁支架,所述左纵梁和右纵梁安装在副车架本体的左右两侧,所述后横梁;的表面开设有应力槽,所述中塔套管的前侧面安装有摆臂前点支架,所述左纵梁和右纵梁的前端均焊接有前防撞梁支架。该新型冲压焊接前副车架,左右纵梁为冲压件,前横梁为冲压管梁和焊接梁相结合的形式,提高了副车架整体型面的尺寸精度,前横梁采用管件和焊接件装配的形式,布置紧凑,降低了对布置空间的要求,通过局部搭接型面与结构的设计,提高了零件之间的匹配搭接精度,提升副车架整体耐久性能和刚度。
