The invention provides a front auxiliary frame, a chassis structure and a vehicle. Front auxiliary frame longitudinal beams on the left side and the right side of the front auxiliary frame are each provided with an upper longitudinal beam and a lower longitudinal beam which are arranged up and down; the front ends of the upper longitudinal beams and the front ends of the lower longitudinal beams on the sides are connected with a front cross beam of a front auxiliary frame, the rear ends of the upper longitudinal beams and the rear ends of the lower longitudinal beams on the sides are connected to a rear cross beam located on the rear portion of the front auxiliary frame, and crumple sections are arranged on the front sections of the upper longitudinal beams and the front sections of the lower longitudinal beams on the sides. The crumple section can be bent and deformed when the front auxiliary frame longitudinal beam bears direct impact force not lower than a preset threshold value, and the front section of the upper longitudinal beam and the front section of the lower longitudinal beam are guided to crumple. According to the front auxiliary frame, the collision force transmission capacity of the front auxiliary frame can be improved, the collision energy absorption effect of the front auxiliary frame can be improved, and the collision safety of the whole vehicle can be improved.

    本发明提供了一种前副车架、底盘结构及车辆,所述前副车架左右两侧的前副车架纵梁均具有上下布置的上纵梁和下纵梁;各侧所述上纵梁和所述下纵梁的前端与前副车架前横梁连接,各侧所述上纵梁和所述下纵梁的后端均连接在位于所述前副车架后部的后横梁上,且各侧所述上纵梁和所述下纵梁的前段均具有溃缩段;所述溃缩段在所述前副车架纵梁受到不低于预设阈值的正碰力时能够折弯变形,并引导所述上纵梁的前段和所述下纵梁的前段发生溃缩。本发明能够增加前副车架的碰撞力传递能力,并能够提高前副车架的碰撞吸能效果,而有助于提升整车碰撞安全性。
