The invention belongs to the technical field of coupler buffers, and particularly relates to a combined buffer and coupler buffer.The combined buffer comprises a rubber part and a thermoplastic elastomer, the rubber part is in a sleeve shape, a through hole is formed in the middle of the thermoplastic elastomer, a cavity is formed in the thermoplastic elastomer, and the cavity surrounds the through hole and communicates with the through hole; the thermoplastic elastomer can be arranged on the outer side of the rubber part in a sleeving mode through the through hole, and the axial size of the thermoplastic elastomer is not larger than that of the rubber part. The buffer capacity and the energy absorption rate are increased while the running stability of a train is improved, the overall springback speed and springback amount are guaranteed, the sensitivity is higher, the buffer can be applied to more scenes, the structural designability is higher, and the technical requirements of different coupler buffers can be better met.

    本发明属于车钩缓冲器技术领域,具体涉及一种组合式缓冲件及车钩缓冲器,包括橡胶件和热塑性弹性体,所述橡胶件为套筒状,所述热塑性弹性体中部设有通孔,热塑性弹性体的内部设有空腔,空腔环绕通孔设置并与通孔连通,所述热塑性弹性体可通过通孔套设在橡胶件的外侧,且热塑性弹性体的轴向尺寸不大于橡胶件的轴向尺寸。本发明提高列车运行平稳性的同时增大了缓冲容量及能量吸收率,并保障整体的回弹速度及回弹量,灵敏度更高,可适用的场景更多,且结构的可设计性更强,能更好地满足不同车钩缓冲器的技术要求。
