The invention discloses a primary suspension device for a rail bogie, which comprises a vertically arranged spring part, longitudinally arranged longitudinal positioning pull rods and transversely arranged transverse positioning pull rods, the spring part is arranged at the top or two sides of an axle box, and the two longitudinal positioning pull rods are in central symmetry about the axis of a bearing; wherein one longitudinal positioning pull rod is higher than the other longitudinal positioning pull rod, the transverse positioning pull rod is arranged at the top of the axle box, the centerline of the transverse positioning pull rod is located over the center line of the bearing, and a vertical shock absorber is further arranged on the axle box. By the adoption of the device, verticalsuspension, longitudinal positioning, transverse positioning and vertical vibration attenuation damping of the primary suspension device can be achieved through independent components respectively, itcan be guaranteed that suspension parameters of the primary suspension device in all directions are more accurate and reliable, and independent design of positioning rigidity of the primary suspension device in all directions can be achieved; and the rigidity in each direction can be optimized at the same time.

    本发明公开了一种用于轨道转向架的一系悬挂装置,包含垂向布置的弹簧部件、纵向布置的纵向定位拉杆和横向布置的横向定位拉杆,所述弹簧部件设于轴箱顶部或两侧,两个所述纵向定位拉杆关于轴承的轴线中心对称,其中一个所述纵向定位拉杆的高度高于另一个所述纵向定位拉杆的高度,所述横向定位拉杆设于轴箱顶部,其中心线在轴承中心线的正上方,所述轴箱上还布置有垂向减振器。采用本装置可实现一系悬挂装置的垂向悬挂、纵向定位、横向定位和垂向减振阻尼分别由独立的部件实现,能保证一系悬挂装置各方向的悬挂参数更准确、可靠,可实现一系悬挂装置各个方向定位刚度的单独设计,使各个方向刚度能同时达到最优。
