The invention discloses a height-adjustable primary suspension device for a railway vehicle bogie, and relates to the technical field of railway vehicle bogie assembly. The device comprises a primaryspring and an axle box, and is characterized by further comprising a height adjusting mechanism used for adjusting the distance between the primary spring and the axle box, the primary spring is coaxially placed at the top of the height adjusting mechanism, and the height adjusting mechanism is coaxially and fixedly connected with a spring mounting seat of the axle box. According to the invention,an adjusting gear matches a toothed thread lifting seat; multiple times of adjustment of the height of the primary suspension device can be achieved only by one-time falling of the bogie, the use frequency and the transfer cost of a large crane and a transfer vehicle are reduced, at least more than 10 working hours are saved for each bogie, and the production efficiency of rail vehicles is improved. And meanwhile, all adjustment work can be completed by only one person through gear transmission and thread lifting, operation is easy and convenient, and the labor intensity of workers is reduced.

    轨道客车转向架用高度可调的一系悬挂装置涉及轨道客车转向架装配技术领域,其包括一系弹簧和轴箱,其特征在于,该装置还包括用于调整一系弹簧和轴箱之间间距的高度调整机构,一系弹簧同轴放置在所述高度调整机构的顶部,所述高度调整机构同轴固连在轴箱的弹簧安装座上。本发明通过调整齿轮和带齿螺纹升降座的配合,实现只需要转向架落成一次,便可以实现一系悬挂装置高度的多次调整,减少了大型起重机和转运车辆的使用频率和转运费用,每台转向架至少节省10个工时以上,提高了轨道车辆的生产效率。同时,该装置通过齿轮传动和螺纹升降实现仅需要1人就可以完成全部调整工作,操作简单、方便,降低了工人的劳动强度。
