Bogies are complex railway vehicle subsystems that are crucial to ensuring reliable performance of vehicles.

Ensure the stability and ride comfort of rail vehicles Bogies are complex railway vehicle subsystems, including brake systems, drive systems, wheel subsystems and bogie frames with auxiliary spring systems. Although different bogies are designed for different purposes, they have the same functionality. This includes supporting the rail vehicle body, helping to ensure the vehicle is stable on the track and providing riding comfort. Connecting directly to the wheelset and bogie frame is the axle case, which contains the axle case bearing system, which is connected to other subsystems and components. The wheel sets can have different configurations and designs depending on the railway gauge, wheel diameter and axial load. Since all these systems are critical to the performance and reliability of rail vehicles, they should be carefully considered when choosing a solution.
