The auxiliary frame mounting mechanism comprises an engine compartment edge beam and an auxiliary frame mounting sleeve, part of the engine compartment edge beam is bent to form a bent part, the engine compartment edge beam is provided with a first mounting hole, and the aperture of the first mounting hole is larger than the outer diameter of the auxiliary frame mounting sleeve. The auxiliary frame mounting sleeve penetrates through the first mounting hole, the first connecting piece is connected with the auxiliary frame mounting sleeve and the inner wall of the first mounting hole, and the first mounting hole is formed in one side of the bending part, so that when the engine compartment edge beam deforms in the bending direction, the auxiliary frame mounting sleeve is connected with the auxiliary frame mounting sleeve and the inner wall of the first mounting hole. The first connecting piece is separated from the auxiliary frame mounting sleeve, or the first connecting piece tends to be separated from the auxiliary frame mounting sleeve. According to the method, the maximum load of falling of the auxiliary frame is achieved through adaptive adjustment according to vehicle requirements, and meanwhile the reliability of the dynamic stiffness requirement, fatigue durability and the like of an auxiliary frame mounting point and the falling requirement in the collision process are guaranteed.
本发明涉及一种副车架安装机构及汽车,包括发动机舱边梁和副车架安装套管,所述发动机舱边梁的部分折弯形成折弯部,所述发动机机舱边梁设有第一安装孔,所述第一安装孔的孔径大于副车架安装套管的外径,所述副车架安装套管穿过所述第一安装孔,还包括第一连接件,所述第一连接件与副车架安装套管和第一安装孔内壁均连接,所述第一安装孔位于所述折弯部的一侧,使得所述发动机舱边梁沿着折弯的方向形变时,所述第一连接件与副车架安装套管脱离连接,或者所述第一连接件产生与副车架安装套管脱离连接的趋势。本发明根据车辆需求适应性调整实现副车架脱落的最大载荷,同时保证副车架安装点的动刚度要求、疲劳耐久等可靠性以及碰撞过程脱落要求。
