The invention discloses a transverse and longitudinal rigidity adjusting method and structure of a primary suspension device. The primary suspension device comprises a base, a top plate, conical springs and a limiting stopper; cavities are formed in the conical springs; and the two conical springs are arranged between the base and the top plate side by side in the longitudinal direction. A limiting stopper is arranged in the cavity of each conical spring; the lower end of the limiting stopper is connected with the base; an axle box seat is arranged on an axle box, the base is installed in theaxle box seat, a stop hole is formed in the lower end of a bogie, the upper end of each conical spring further penetrates through the top plate to extend into the stop hole of the bogie, and when thebogie moves relative to the axle box in the transverse direction or the longitudinal direction and the limiting stop abuts against the inner sides of the conical springs, the primary suspension devicecan generate variable rigidity. According to the invention, the capacity of a vehicle for passing through a small-curvature-radius curve can be remarkably improved, the primary suspension space is greatly saved, and the weight of the bogie is reduced.

    一种一系悬挂装置的横向和纵向刚度调节方法及结构,一系悬挂装置包括底座、顶板、锥形弹簧和限位止挡,锥形弹簧内开有空腔,底座和顶板之间沿纵向方向并排设置有两个锥形弹簧,每个锥形弹簧的空腔中都设置有限位止挡,且限位止挡的下端与底座连接,轴箱上设有轴箱座,底座安装在轴箱座中,转向架下端开有止挡孔,每个锥形弹簧的上端还穿过顶板伸入到转向架的止挡孔中,当转向架相对于轴箱在横向方向或纵向方向上产生相对移动,且限位止挡与锥形弹簧的内侧相顶时,一系悬挂装置会产生变刚度。本发明能显著提高车辆通过小曲率半径弯道的能力,且极大节省了一系悬挂空间,降低了转向架的重量。
