The embodiment of the invention provides a damping spring and a bogie primary spring suspension device. The damping spring comprises an upper spring seat assembly and a lower spring seat assembly. The upper ends and the lower ends of the rubber spring body and the air spring body are fixed to the upper spring seat assembly and the lower spring seat assembly respectively, the air spring body is provided with an air bag, the rubber spring body is located in the air bag, and the air bag is provided with an air channel communicated with the outside. The damping spring can provide the vertical rigidity of the primary spring in a narrow space, and the requirements of the bogie for different vertical rigidity parameters of the primary spring under the linear working condition and the curve working condition can be separated; and during curve operation, air is supplied to the air spring bodies in the damping springs on the outer side through control, so that the comprehensive vertical rigidity of the damping springs on the outer side is improved, and the anti-side-rolling capacity of the first system of the vehicle bogie is improved.
本申请实施例中提供了一种阻尼弹簧及转向架一系弹簧悬挂装置,包括:上弹簧座组件和下弹簧座组件;橡胶弹簧体和空气弹簧体,橡胶弹簧体、空气弹簧体的上下两端分别与上弹簧座组件和下弹簧座组件固定,空气弹簧体具有气囊,橡胶弹簧体位于气囊中,气囊具有与外界连通的气路。上述阻尼弹簧可以在狭小空间提供一系弹簧的垂向刚度,能够实现将直线工况与曲线工况下转向架对一系弹簧不同垂向刚度参数的需求的分离;在曲线运行时,通过控制给外侧的阻尼弹簧中的空气弹簧体供风,提高外侧阻尼弹簧的综合垂向刚度,提升车辆转向架一系的抗侧滚能力。
