The invention discloses a primary axle box suspension device of a railway vehicle bogie. An axle box primary suspension is arranged inside and outside each wheel of a whole wheel pair of the bogie; the outer axle box suspension comprises a longitudinally-arranged outer axle box positioning pull rod, a primary vertical shock absorber, a vertically-arranged outer axle box spring component, an outer axle box body, an outer axle box bearing, an outer axle box end cover and an outer axle box bearing positioning check ring. The inner axle box suspension comprises a longitudinally arranged inner axle box positioning pull rod, a vertically arranged inner axle box spring component, an inner axle box body, an inner axle box bearing, an inner axle box end cover and an inner axle box bearing positioning check ring. By adopting the double-axle box one-stage suspension scheme, the stress state of the axle is better than that of the axle of a conventional outer axle box bogie and an inner axle box bogie, so that the whole wheel set axle can be lightened to the maximum extent, and the unsprung mass of the bogie is smaller.

    本发明公开了一种轨道车辆转向架的一系轴箱悬挂装置,所述转向架整体轮对每个车轮内、外布置轴箱一系悬挂,所述外轴箱悬挂包含纵向布置的外轴箱定位拉杆、一系垂向减振器、垂向布置的外轴箱弹簧部件、外轴箱体、外轴箱轴承、外轴箱端盖和外轴箱轴承定位挡圈。所述内轴箱悬挂包含纵向布置的内轴箱定位拉杆、垂向布置的内轴箱弹簧部件、内轴箱体、内轴箱轴承、内轴箱端盖和内轴箱轴承定位挡圈。通过采用该双轴箱一系悬挂方案,车轴受力状态比常规外轴箱转向架和内轴箱转向架车轴更加良好,从而可实现整体轮对车轴最大程度的轻量化,进而实现更小的转向架簧下质量。
