The invention discloses a trailer and a special vehicle chassis precision casting. The trailer comprises a chassis and a crash barrier, wherein a first buffer column and a second buffer column are fixedly mounted at the lower end of one side surface of the crash barrier in parallel; a sleeve is fixedly mounted on the lower surface of the chassis; buffer cavities are formed in the sleeve and the chassis correspondingly, the first buffer column and the second buffer column are movably inserted into the buffer cavities in the corresponding positions correspondingly, first springs are arranged inthe buffer cavities, and a plurality of anti-collision buffer mechanisms are evenly and fixedly installed on the surface of the other side of the crash barrier in parallel from top to bottom. When thecrash barrier is slightly collided, the buffer plate moves towards one side of a strip-shaped box under the action of collision force, the collision force can be buffered through the acting force ofthe second spring, when the crash barrier is subjected to violent collision, the first buffer column and the second buffer column can go deep into the buffer cavity, and meanwhile, the effect of effectively reducing damage to a colliding vehicle and a collided vehicle is achieved through the side guardrail anti-collision device.
本发明公开了一种拖车及特种车辆底盘精密铸件,包括底盘和防撞栏,防撞栏一侧表面下端平行固定安装有第一缓冲柱和第二缓冲柱,所述底盘下表面固定安装有套筒,所述套筒内部及底盘内部均开设有缓冲腔,所述第一缓冲柱及第二缓冲柱分别活动插设于对应位置的缓冲腔内,缓冲腔内设置有第一弹簧,所述防撞栏另一侧表面自上而下均匀平行固定安装有多个防撞缓冲机构。本发明防撞栏被轻度碰撞时,缓冲板在碰撞力作用下向条型盒一侧移动,通过第二弹簧作用力能够缓冲碰撞力,当防撞栏受到剧烈碰撞时,第一缓冲柱和第二缓冲柱能够深入缓冲腔内,同时通过侧护栏防撞装置,起到有效降低碰撞车辆和被碰撞车辆受到损伤的作用。
