The invention belongs to the technical field of automobile suspensions, and provides a front auxiliary frame, a front suspension and an automobile, the front auxiliary frame comprises a longitudinal beam, the longitudinal beam is in a hollow long box shape, and a connecting structure used for installing a swing arm is arranged in the longitudinal beam; the side, corresponding to the side wall of the vehicle body and facing the outside of the vehicle, of the longitudinal beam is provided with an installation hole used for the swing arm to penetrate in. The mounting hole is formed in the longitudinal beam, the connecting point of the swing arm and the longitudinal beam is arranged in the longitudinal beam, the overall structure of the longitudinal beam cannot be affected, and the influence on the strength of the longitudinal beam is reduced. The connecting structure is arranged in the longitudinal beam and can be connected with the upper portion and the lower portion of the longitudinal beam at the same time, the connecting strength between the connecting structure and the longitudinal beam is improved, and stress deformation and cracking of the connecting structure are avoided. Meanwhile, the connecting structure does not need to be located above or below the longitudinal beam, the mounting point position of the swing arm does not need to be raised or lowered, and the swing arm is convenient to arrange.

    本发明属于汽车悬架技术领域,提供了一种前副车架、前悬架及汽车,前副车架,包括纵梁,所述纵梁为中空的长盒状,所述纵梁内设置用于安装摆臂的连接结构,所述纵梁对应于车身侧围且朝向车外的一侧上开设有用于所述摆臂穿入的安装孔。本发明通过在纵梁上开设安装孔,将摆臂与纵梁的连接点设置在纵梁内部,不会影响纵梁的整体结构,降低对纵梁强度的影响。连接结构设置在纵梁内部,可以同时与纵梁上部及下部连接,增加了连接结构与纵梁之间的连接强度,避免连接结构受力变形、开裂。同时,连接结构无需位于纵梁的上方或下方,无需提高或降低摆臂的安装点位,便于摆臂的布设。
