The invention provides an integrated laminated spring and a railway vehicle bogie suspension vibration reduction system. The railway vehicle bogie suspension vibration reduction system is subjected to lightweight and intelligent design. A laminated spring, a motor node, a center pin sleeve, a rotating arm node, a liquid rubber node, a traction node, a motor backstop, a transverse buffer, a small-amplitude tilting system and a plate spring are designed, and through structural optimization and new structure integrated design, redundancy is removed, the number of parts is reduced, and the overall weight of the parts is reduced; through the lightweight design of materials, the weight of the parts is reduced on the premise that the structural performance is guaranteed; through system function integration, a plurality of parts with different functions are integrated into a single integral system component, and the purpose of weight reduction is achieved. The volume of liquid in a liquid cavity of the liquid rubber composite node is actively controlled, the height difference of air springs on the two sides of a vehicle body is actively controlled, the response speed of a bogie component is increased, and the requirement of a higher-speed-grade railway vehicle is met.

    本发明提供了一种一体化叠层弹簧和轨道车辆转向架悬挂减振系统,对轨道车辆转向架悬挂减振系统进行轻量化和智能化设计。对叠层弹簧、电机节点、中心销套、转臂节点、液体橡胶节点、牵引节点、电机止挡、横向缓冲器、小幅倾摆系统和板弹簧进行设计,通过结构优化和新结构整合设计,去除冗余,减少零部件数量,降低部件整体重量;通过材料轻量化设计,保证结构性能的前提下,减轻这些部件重量;通过系统功能集成,将不同功能的多个零部件部件集成为单一整体系统部件,达到减重的目的。对液体橡胶复合节点液体空腔中的液体体积进行主动控制,对车体两侧的空簧的高度差进行主动控制,提高转向架部件的反应速度,达到更高速等级轨道车辆的要求。
