The invention belongs to the technical field of aluminum alloy auxiliary frames, and provides a front cross beam and longitudinal beam mounting assembly of a lightweight welding aluminum alloy auxiliary frame, which comprises a front cross beam and a longitudinal beam, the front cross beam is arranged at the front part of the longitudinal beam, one end of the longitudinal beam is connected to the rear part of the front cross beam, and a vehicle body mounting bracket is connected between the front cross beam and the longitudinal beam. The vehicle body installation support is provided with a transmission connection structure which transmits collision force transmitted by the front cross beam to the longitudinal beam and disperses the collision force to the middle cross beam and the rear casting. The front cross beam and the longitudinal beam are connected through the front vehicle body mounting bracket, so that on one hand, the problem of position height difference of U-shaped grooves of the front cross beam and the longitudinal beam is ingeniously solved, and collision force (or energy) transmitted in harsh front 25% small offset collision passes through the auxiliary frame energy absorption box mounting bracket, the front cross beam, the vehicle body mounting bracket and the longitudinal beam; and the small-offset collision bending mode meets the target requirement.
本发明属于铝合金副车架技术领域,提供了一种轻量化焊接铝合金副车架的前横梁与纵梁安装组件,包括有前横梁和纵梁,前横梁设置在纵梁的前部,纵梁的一端连接在前横梁的后部,前横梁和纵梁之间连接有车身安装支架,车身安装支架上具有将前横梁传递来的碰撞力传递至纵梁并分散至中间横梁和后铸件的传递连接结构。本发明的优点在于通过前车身安装支架连接前横梁、纵梁和纵梁,一方面巧妙解决前横梁与纵梁的U型槽位置高度差问题,将苛刻的正面25%小偏置碰撞中传递来的碰撞力(或能量)经副车架吸能盒安装支架、前横梁、车身安装支架、纵梁后,分散至副车架中间横梁和后铸件,小偏置碰撞折弯模式满足目标需求。
