前副车架总成和车辆

Abstract

本申请涉及车辆底盘技术领域提供了一种前副车架总成和车辆，前副车架总成包括：车架纵梁；安装板，所述安装板连接在所述车架纵梁的前端，并形成有向第一方向的第一侧凸出设置的隆起部，所述隆起部在所述第一方向的第二侧形成有至少部分位于所述车架纵梁所述第一侧的容置空间；加强支架，所述加强支架与所述车架纵梁相连，且部分所述加强支架置于所述容置空间内并与所述安装板连接配合。由此，当车辆发生碰撞时，自前向后传递的碰撞力可以先作用在隆起部处，并通过隆起部向位于安装板后侧的加强支架一侧传递，加强支架可以将力传递至车架纵梁，从而对车辆发生小重叠碰撞时的碰撞力传递路径进行优化，有助于提升前副车架总成的整体碰撞安全性能。
