心盘组件以及具有其的铁路车辆
By designing diameter variations and limiting structures for multiple shaft sections and bearing components, the center plate assembly can effectively disperse forces, solving the problem that traditional center plates cannot drive the running gear to lift, thereby improving the operational stability and safety of railway vehicles.

AI Technical Summary
Technical Problem
Traditional center plate structures cannot effectively lift the running gear when subjected to vertical upward force, affecting vehicle maintenance efficiency and safety.
Method used
Design a core plate assembly, including a shaft and bearing components. The shaft is composed of multiple shaft segments with gradually changing diameters. The cross-sectional area of the bearing components first increases and then decreases. With the help of a limiting structure, force dispersion and vertical lifting are achieved.
Benefits of technology
It effectively disperses forces, reduces structural fatigue, improves operational stability and safety, and balances vertical load-bearing and lifting functions.
