The invention discloses a bogie primary suspension device and a railway vehicle. The primary suspension device comprises a framework, a suspension unit and an axle box, the framework is positioned above the axle box; bearing platforms are arranged on the axle boxes and used for fixing the suspension units; the suspension unit comprises a spiral spring, a positioning structure and a rigidity adjusting component; the spiral spring is fixed between the framework and a bearing platform of the axle box; the positioning structure is located in the spiral spring and provided with an inner cavity. The rigidity adjusting component is arranged in the inner cavity and used for adjusting the transverse rigidity and the longitudinal rigidity of the axle box. The primary suspension device not only can adjust the rigidity in the transverse direction, the longitudinal direction and the vertical direction, improve the bearing capacity of a vehicle and prolong the service life of an axle box system, but also can effectively reduce wheel track abrasion, restrain snaking motion and side rolling motion of a bogie, and meet the running dynamics performance requirements of stable running and stable performance on the premise of improving the critical running speed of the vehicle.

    本发明公开了一种转向架一系悬挂装置及轨道车辆。该一系悬挂装置包括构架、悬挂单元和轴箱;构架位于轴箱的上方;轴箱上设置有承台,用于固定悬挂单元;悬挂单元包括螺旋弹簧、定位结构和刚度调节部件;螺旋弹簧固定于构架和轴箱的承台之间;定位结构位于螺旋弹簧内,定位结构设置有内腔;刚度调节部件设置于内腔内,用于调节轴箱的横向刚度和纵向刚度。该一系悬挂装置不仅能够调整横、纵、垂三向刚度,提高车辆承载能力延长轴箱系统使用寿命,还能有效地降低轮轨磨耗、抑制转向架蛇行运动和侧滚运动,在提高车辆运行临界速度的前提下实现运行平稳和稳定性能的运行动力学性能要求。
