Provided are a rigidity adjusting method and structure for conical springs of a primary suspension device. The primary suspension device comprises a base, conical springs and limiting stoppers. Each conical spring comprises a rubber body and a mandrel. Stopping holes are formed in the lower end of a bogie, and the upper ends of the mandrels are installed in the stopping holes of the bogie. Cavities are formed in the rubber bodies and the mandrels. The two conical springs are arranged in the base side by side in the longitudinal direction, one limiting stopper is arranged in a cavity of each conical spring, and the lower end of each limiting stopper is connected with the base. An axle box is provided with an axle box seat, and the base is installed in the axle box seat. When the bogie movesrelative to the axle box in the vertical direction and the lower ends of the mandrels abut against the limiting stoppers, the primary suspension device can generate variable rigidity in the verticaldirection. 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锥形弹簧的刚度的调节方法及结构,一系悬挂装置包括底座、锥形弹簧和限位止挡,锥形弹簧包括橡胶体和芯轴,转向架下端开有止挡孔,芯轴上端安装在转向架的止挡孔中,橡胶体和芯轴内都开有空腔;底座中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,当转向架相对于轴箱在垂向方向上产生相对移动,且芯轴下端与限位止挡相顶时,一系悬挂装置会在垂向方向上产生变刚度。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。
