The invention belongs to the technical field of buffers, and particularly relates to a longitudinal traction buffering device for a road-rail car. Comprising a coupler, a buffer, a slave plate and a coupler yoke, the buffer comprises a barrel, a first piston, a connecting frame, a traction guide rod and a conversion unit. When a traction guide rod of the buffer is subjected to impact force to move leftwards, a first piston moves leftwards to extrude hydraulic oil and push a second piston at the moment, a second spring is placed between a baffle and the second piston, so that when the second piston is pushed, the second piston extrudes the second spring, and then the impact force is shared by elastic potential energy of the second spring; therefore, the purpose of sharing the buffering force is achieved; similarly, the buffering force can be shared when the traction guide rod moves rightwards.
本发明属于缓冲器技术领域,具体的说是一种公铁两用车用纵向牵引缓冲装置;包括:车钩、缓冲器、从板以及钩尾框;所述缓冲器包括:筒体、一号活塞、连接框、牵引导向杆、转化单元;本发明通过当缓冲器的牵引导向杆受到冲击力左移时,此时一号活塞左移,挤压液压油,推动二号活塞,由于挡板与二号活塞之间放置有二号弹簧,故在推动二号活塞时,二号活塞挤压二号弹簧,进而将冲击力分担为二号弹簧的弹性势能,以此实现分担缓冲力的目的;同理牵引导向杆右移时也能达到分担缓冲力效果。
