The invention relates to a vehicle auxiliary frame, a front cabin assembly and a vehicle, the vehicle auxiliary frame is used for being arranged in a front cabin, and the vehicle auxiliary frame comprises a longitudinal beam extending in the same direction as the advancing direction of the vehicle; the cross beams are perpendicular to the longitudinal beams and connected with the longitudinal beams, and the cross beams and the longitudinal beams define a frame structure; a bendable weak area is arranged at the end, close to a cab, of each longitudinal beam so that the frame structure can move in the direction close to the cab when the front face of the front cabin collides. The vehicle auxiliary frame structure is of the frame structure composed of the longitudinal beams and the transverse beams, the bendable weak areas are arranged on the sides, close to the cab, of the longitudinal beams, when the front face of a front engine room is collided, the weak areas are bent firstly, and the frame structure retreats in the direction close to the cab; a larger crumple space is provided for the front cabin, the rigidity of the front cabin is reduced, and therefore the effect of protecting the safety of passengers is achieved.
本公开涉及一种车辆副车架、前舱总成及车辆,车辆副车架用于设置在前机舱内,包括:纵梁,与车辆的行进方向同向延伸;横梁,与所述纵梁垂直设置且与所述纵梁连接,所述横梁与所述纵梁合围成框架结构;所述纵梁靠近驾驶舱的一端设置有可弯折的薄弱区,以使在所述前机舱正面发生碰撞时该框架结构向靠近所述驾驶舱的方向移动。本公开的车辆副车架构造为由纵梁及横梁组成的框架结构,纵梁靠近驾驶舱的一侧设有可弯折的薄弱区,在前机舱的正面发生碰撞时,薄弱区首先发生弯折,框架结构向靠近驾驶舱的方向后退,为前机舱提供更大的溃缩空间、降低前机舱刚度,从而达到保护乘员安全的效果。
