The invention provides a method and a structure for adjusting the vertical rigidity 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, a stopping hole is formed in the lower end of a bogie, the upper end of the mandrel is installed in the stopping hole of the bogie, and cavities are formed in the rubber body and the mandrel; the two conical springs are arranged in the base side by side in the longitudinal direction, the limiting stoppers are arranged in the cavities ofthe conical springs, each limiting stopper comprises a stop base and a stop rod, and the stop rod is integrally formed above the stop base; and an axle box is provided with an axle box seat, the baseis installed in the axle box seat, and when the bogie moves relative to the axle box in the vertical direction and the lower end of the mandrel abuts against the stop seats in the vertical direction,the primary suspension device can generate variable rigidity in the vertical direction. 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.
一系悬挂装置的垂向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,限位止挡包括止挡座和止挡杆,止挡杆一体成型在止挡座上方;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,且芯轴下端与止挡座在垂向方向相顶时,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。
