The invention relates to a front anti-collision beam assembly which comprises a front cross beam and energy absorption boxes arranged on the inner sides of the two ends of the front cross beam, a hydraulic buffer valve is arranged in each energy absorption box, the front ends of the hydraulic buffer valves are fixedly connected with the energy absorption boxes, and the hydraulic buffer valves are fixed to a longitudinal beam of a vehicle body. According to the technical scheme, the rubber and the hydraulic buffering structure are added to serve as first-order buffering, instantaneous impact force is reduced, the protection effect on passengers is good, the damage rate of the anti-collision beam is reduced during low-speed collision, and economical efficiency is good.
本发明涉及一种前防撞梁总成,包括前横梁及设置于前横梁两端内侧的吸能盒,在每个吸能盒内均设置有一个液压缓冲阀,液压缓冲阀的前端与吸能盒固定连接,液压缓冲阀固定于车身纵梁上。本技术方案通过增加橡胶和液压缓冲结构作为一阶缓冲,降低瞬时冲击力,对乘员保护效果较好,且低速碰撞时防撞梁损坏率降低,经济性较好。
