A commercial vehicle cab collision buffering device comprises a buffering beam, a force transmission plate, an energy absorption beam, a bolt set, a first nut set, a baffle, a buffering spring, a guide plate, a sliding rod, a longitudinal beam, a second nut set and an installation plate. The installation plate is fixed to the front end of a cab floor longitudinal beam, the buffer beam is a thin-wall beam and is fixedly connected with the installation plate through a bolt set and a first nut set, and a round hole larger than the diameter of the sliding rod is formed in the side wall, close to the longitudinal beam, of the buffer beam. The force transmission plate is arranged on the inner surface of the buffering beam, the buffering beam is filled with the energy absorption beam, the surfaceof the guide plate is provided with a round hole with the diameter larger than that of the sliding rod and arranged in the longitudinal beam, and one end of the sliding rod is provided with a thread,sequentially penetrates through the buffering spring, the baffle and the second nut set and passes through the buffering beam and the round hole in the guide plate. Through multiple ways of spring compression, energy absorption beam deformation, buffer beam collapse and the like, head-on collision energy of a cab is buffered and consumed, the buffering and energy absorption effect is good, the structure is simple, and practicability is high.

    一种商用车驾驶室碰撞缓冲装置,包括缓冲梁、传力板、吸能梁、螺栓组、螺母组一、挡板、缓冲弹簧、导向板、滑杆、纵梁、螺母组二、安装板。所述安装板固定于驾驶室地板纵梁前端,所述缓冲梁为薄壁梁,且通过螺栓组、螺母组一与安装板连接固定,缓冲梁靠近纵梁侧壁设有大于滑杆直径的圆孔;所述传力板设置于缓冲梁内表面,所述吸能梁填充于缓冲梁内,所述导向板表面设有大于滑杆直径的圆孔,且设置于纵梁内部,所述滑杆一端设置有螺纹,依次穿过缓冲弹簧、挡板、螺母组二,并通过缓冲梁、导向板上圆孔。本发明通过弹簧压缩、吸能梁变形、缓冲梁溃缩等多种途径,缓冲和消耗驾驶室正面碰撞能量,缓冲吸能效果好,结构简单,实用性强。
