The invention discloses a waistband type air spring and swing bolster combined structure which comprises a waistband type air spring and a swing bolster, a through hole is formed in a swing bolster lower cover plate of the swing bolster, the air spring rotates reversely, the bottom of the air spring penetrates through the through hole, and the air spring is partially embedded into the swing bolster. The invention further provides a vehicle bogie which comprises the combined structure of the belt type air spring and the swing bolster and a bogie side beam, and the top of the air spring is fixedly connected with the bogie side beam below the air spring. Compared with the prior art, according to the combined structure of the belt type air spring and the swing bolster and the vehicle bogie, the curvature of the swing bolster can be designed to be smaller, the gap between the swing bolster and the underframe bolster beam is increased, the operation space for installing bolts between a rotary support and a vehicle body is larger, and fasteners are convenient to install. And meanwhile, the stress at the bent part is reduced due to the smaller bending angle, and the safety of the vehicle in the running process is improved.

    本申请公开了一种腰带式空气弹簧与摇枕的组合结构,包括腰带式空气弹簧与摇枕,其所述摇枕在其摇枕下盖板处开设通孔,所述空气弹簧倒转且其底部穿过所述通孔,使空气弹簧部分嵌入摇枕内部。本申请还提供一种车辆转向架,包括如上所述的腰带式空气弹簧与摇枕的组合结构以及转向架侧梁,所述空气弹簧顶部与下方的转向架侧梁固定连接。与相关技术相比,本发明腰带式空气弹簧与摇枕的组合结构及车辆转向架,摇枕的弯曲度可以设计得更小,增加摇枕与底架枕梁之间的间隙,使得回转支撑与车体之间的安装螺栓的操作空间更大,便于安装紧固件。同时更小的折弯角减小了折弯处的应力,提高车辆运行过程的安全性。
