Rail Joints

Introduction of Railway Joints

As the core equipment of modern rail transit, the reliability of the connection system of rail vehicles directly affects the safety and efficiency of train operation.

1. Load-bearing connection bracket system: As the mechanical center of the entire vehicle structure, the connection bracket is formed by high-strength alloy casting and strengthened through three-dimensional finite element topology optimization design. This component has the following technical characteristics:

• Multi-directional load-bearing system: It can simultaneously withstand longitudinal traction force (maximum load ≥ 500kN), vertical pressure (design load 800kN), and lateral shear force, with a dynamic load factor of 1.8.

2.Reinforced hanging rib plate assembly: As a key force transmission component for the connection between the car body and the bogie, the new hanging rib plate is manufactured using laser welding technology and incorporates several innovative designs:

• Variable cross-section bionic rib design: Based on biomechanical principles, the gradually changing cross-section structure effectively disperses stress concentration.
• Nano-coating protection: The surface is treated with HVOF sprayed tungsten carbide coating, increasing wear resistance.
• Modular quick-release structure: Equipped with a patented wedge locking device, maintenance time is reduced by 70%.

3. Dynamic adaptive movable crossbeam assembly: As the movement hub of the connection system, this component has achieved three technological innovation breakthroughs:

• With a spherical bearing and cross-slot composite structure, it automatically compensates for ±5° deflection angles.
• Integrated with a micro-quantitative oil injection device, it automatically replenishes 12ml of grease every 100,000 kilometers of operation.
• With 7-series aluminum alloy forging technology, it reduces weight by 35% while maintaining a tensile strength of 900MPa.

Advantages of Railway Joints

Engineering practice shows that the new generation of connection systems, by optimizing the coordination of components, reduces the longitudinal impact force of the entire vehicle by 28% and extends the fatigue life of key connection points to 1.8 million kilometers. Particularly in terms of curve passing performance, the lateral force between the wheel and rail is reduced by 15% compared to traditional structures, fully demonstrating the progress of modern rail vehicle connection technology.
