The invention belongs to the field of vehicles, and provides an auxiliary frame, a vehicle and a vehicle front end collision load transfer method.The auxiliary frame comprises a frame longitudinal beam and a vehicle body mounting frame, the frame longitudinal beam is provided with a first end and a second end which are oppositely arranged in the length direction of the frame longitudinal beam, and the first end is provided with a first weakening part capable of generating induced deformation when the vehicle collides; the vehicle body mounting frame comprises a first connecting section connected with the second end and a second connecting section used for being connected with a vehicle body, the first connecting section is provided with a second weakening part capable of breaking and losing efficacy when the vehicle collides, and the second connecting section is of a reinforcing structure capable of keeping connection with the vehicle body when the vehicle collides. When a vehicle has a head-on collision, the energy absorption effect of the auxiliary frame is improved through induced deformation of the first weakening part and fracture failure of the second weakening part, the second connecting section is always connected with the vehicle body, the integrity of connection between the rear end of the auxiliary frame and the vehicle body is effectively guaranteed, and the safety of the vehicle is greatly improved.
本申请属于车辆领域,提供了一种副车架、车辆及车辆前端碰撞载荷传递方法,包括:车架纵梁以及车身安装架,车架纵梁沿自身长度方向具有相对设置的第一端和第二端,第一端具有在车辆发生碰撞时能够发生诱导变形的第一弱化部;车身安装架包括连接第二端的第一连接段及用于连接车身的第二连接段,第一连接段具有在车辆发生碰撞时能够发生断裂失效的第二弱化部,第二连接段为在车辆发生碰撞时能够与车身保持连接的加强结构。在车辆发生正面碰撞时,通过第一弱化部发生诱导变形,第二弱化部断裂失效,有利于提升副车架的吸能效果,而第二连接段与车身始终保持连接,有效保证副车架的后端与车身连接的完整性,大大提高了车辆的安全性。
