The invention discloses an auxiliary frame assembly and a vehicle, the auxiliary frame assembly comprises a frame longitudinal beam, at least part of the frame longitudinal beam is constructed to be an inclined section, and the inclined section is constructed to obliquely extend outwards from back to front; the mounting bracket is mounted on the inclined section through a mounting bolt; the front end of the inner side of the lower swing arm is movably connected with the mounting bracket through a connecting bolt; wherein the axis of the connecting bolt extends in the front-back direction, collision force is suitable for sequentially passing through the inclined section, the mounting bolt and the mounting support during collision, and the mounting support acts on the connecting bolt and enables the connecting bolt to be broken before the mounting bolt. According to the auxiliary frame assembly, after the connecting bolts are broken due to the shearing force of the installation support, the lower swing arm is thrown out towards the transverse outer side of the vehicle, more serious structural damage to the installation support or the lower swing arm and the like can be reduced, and potential maintenance cost and personal risks can be reduced.
本发明公开了一种副车架组件和车辆,所述副车架组件,包括:车架纵梁,车架纵梁的至少部分构造为倾斜段,倾斜段构造为从后往前朝外倾斜延伸;安装支架,安装支架通过安装螺栓安装于倾斜段;下摆臂,下摆臂的内侧前端与安装支架通过连接螺栓可活动地相连;其中,连接螺栓的轴线沿前后方向延伸,且在碰撞时碰撞力适于依次经过倾斜段、安装螺栓和安装支架,安装支架作用于连接螺栓且使连接螺栓先于安装螺栓发生断裂。本发明的副车架组件,在连接螺栓受到安装支架的剪切力断裂后,下摆臂朝向车辆横向的外侧甩出,可减少安装支架或下摆臂等更严重的结构损坏,可减少潜在的维修成本和人身风险。
