The invention discloses a passenger car front auxiliary frame, and relates to the technical field of automobile parts, the passenger car front auxiliary frame comprises a front auxiliary frame body, two corners of the front auxiliary frame body are integrally provided with fixing ends, the two fixing ends are internally provided with fixing ports, and the two fixing ports are internally provided with fixing shafts and fixing sleeves; the fixing sleeve is rotationally connected with the inner wall of the fixing opening; the two sharp corners of the limiting block are used for limiting the positions of the first limiting tooth and the second limiting tooth of the fixing shaft, and it is ensured that the rotating range of the fixing shaft in the fixing end is small; a spring piece deforms under the condition that the fixed shaft is subjected to large torsion, so that a limiting block or a fixed sleeve is prevented from being damaged, the fixed shaft can be limited again after the torsion is removed, the fixed sleeve can be further limited by a first rack, limiting is firmer, the first rack can be quickly placed in a reserved groove, and the first rack is prevented from being damaged. And interference of the first rack is avoided.

    本发明公开了一种乘用车前副车架,涉及汽车零部件技术领域,包前副车架架体,所述前副车架架体的两拐角处一体设置有固定端,两个所述固定端的内部均开设有固定口,且两个固定口的内部均放置有固定轴和固定套,固定套用于固定口的内壁转动连接;本发明通过,利用限位块的两尖角将固定轴的第一限位齿和第二限位齿进行位置限制,确保固定轴在固定端内部转动范围较小;在固定轴受到扭力较大的情况下弹簧片发生变形,从而避免限位块或者固定套发生损坏,待扭力撤去后可以再次对固定轴进行限位,第一齿条可以进一步将固定套进行限位,限位更加牢靠,可以快速将第一齿条受到预留槽内部,避免第一齿条发生干涉。
