The invention discloses a buffer device, a coupler and a rail wagon. The buffer device comprises a mounting base, a center pin, a connecting body and a buffer element, a hollow mounting cavity is formed in the mounting base, and the center pin is mounted in the mounting base; a buffer hole with the size larger than the maximum size of the cross section of the center pin is formed in the connectingbody, and the connecting body extends into the mounting cavity and sleeves the center pin through the buffer hole; the buffer element is an elastic element, is arranged on the center pin in a sleeving manner, is arranged in the mounting cavity and is positioned between the connecting body and the mounting base; and one end of the buffer element is fixed, and the other end of the buffer element islimited through the connecting body. According to the buffer device provided by the invention, thecoupler, the buffer device and a mounting structure of the rail wagon are simplified, the connectionfree gap is reduced, and the longitudinal traction, compression and vertical buffer characteristics of the wagon are optimized. Therefore, longitudinal dynamic stability and power performance of trainoperation are improved, longitudinal and vertical impact of a train is improved, and part abrasion and cracking faults are reduced.

    本发明公开了一种缓冲装置、车钩以及铁路货车,缓冲装置包括安装座、中心销、连接体和缓冲元件,安装座内部具有一中空的安装腔,中心销安装于安装座中;连接体上设置有尺寸大于中心销横截面最大尺寸的缓冲孔,连接体伸入安装腔中,且通过缓冲孔套装于中心销上;缓冲元件为弹性元件,缓冲元件套装于中心销上,缓冲元件设置于安装腔中、且位于连接体与安装座之间;缓冲元件的一端固定、另一端通过连接体限位。本发明提供的缓冲装置,简化铁路货车车钩缓冲装置与安装结构,减少连接自由间隙,优化车辆纵向牵引、压缩和垂向缓冲特性。从而提高列车运行的纵向动态稳定和动力性能,改善车辆纵向和垂向冲击,降低部件磨耗和裂损故障。
