The invention relates to the technical field of automobile chassis, in particular to a front auxiliary frame structure and an automobile. Longitudinal beams (2) are arranged at the two ends of the rear cross beam (1) respectively. The longitudinal beams (2) are respectively provided with a bending collapse structure and a collision falling structure; the longitudinal beam (2) is connected with a vehicle body; the bending and collapsing structures are bent during collision through the longitudinal beams, so that collision energy is absorbed; therefore, the balance of rigidity, strength and collision energy absorption of the whole structure of the front auxiliary frame can be effectively realized; according to the collision falling-off structure, when front collision happens to an automobile, the front auxiliary frame is separated from an automobile body, an engine is guided to sink, and therefore the deformation energy absorption space of a cabin is increased, and impact and deformation to a passenger compartment are effectively reduced; the energy absorption effect of the front auxiliary frame can be effectively enhanced.
本发明涉及汽车底盘技术领域,具体地说,本发明涉及一种前副车架结构及汽车,包括后横梁(1);所述后横梁(1)的两端分别设有纵梁(2);所述纵梁(2)上分别设有折弯溃缩结构和碰撞脱落结构;所述纵梁(2)与车身连接;折弯溃缩结构通过纵梁在碰撞时折弯,吸收碰撞的能量;从而能够有效实现前副车架整体结构的刚度、强度和碰撞吸能的平衡;碰撞脱落结构在汽车发生正面碰撞时,通过使前副车架与车身分离,引导发动机下沉,从而增加机舱的变形吸能空间,有效减少对乘员舱的冲击和变形;能够有效加强前副车架的吸能效果。
