Product Description

Main uses
Fix the position of the steel rail
The rails are firmly clamped onto the sleepers or track plates by elastic clamping force to prevent longitudinal crawling, lateral displacement or overturning of the rails.
2. Buffer dynamic loads
The elastic deformation of the elastic bar is utilized to absorb the impact force of the train wheel-rail, reduce the vibration and noise of the track, and extend the service life of the rails and sleepers.
3. Insulation protection
Some elastic fasteners are made of insulating materials (such as nylon gaskets) to prevent short circuits in the track circuit and ensure the normal operation of the signal system.
4. Adjust the gauge and the slope at the bottom of the rail
The height and gauge of the rails can be fine-tuned through the matching pads or adjustment parts to meet the design requirements of different lines.

 

Usage scenarios
Conventional speed railway
For ordinary railways with mixed passenger and freight operations, such as Type III elastic fasteners, it is necessary to take into account both load-bearing capacity and durability.
2. High-speed railway
High-elasticity and high-fatigue-strength fasteners (such as Vossloh elastic strips and domestic WJ-8 type) are adopted to cope with the frequent dynamic load impact of high-speed trains.
3. Heavy-haul railway
It uses reinforced elastic bars (such as the E-type elastic bars from the United States) to withstand the high-intensity pressure of heavy-duty trucks.
4. Urban rail transit
Insulating elastic couplings commonly used in subways, light rails, etc., have both vibration damping and electrical insulation functions.
5. Special locations
Sections such as Bridges, tunnels, and small-radius curves should be equipped with anti-loosening designs or special elastic strips to enhance the anti-deformation capacity.

 

Selection considerations
Line speed grade: High-speed lines require higher elasticity and fatigue life.
Axle load and transportation capacity: Heavy-duty lines require greater clamping force and stronger wear resistance.
Environmental conditions: Anti-corrosion treatment is required in areas with high humidity and large temperature differences.
Convenience of maintenance: Some fasteners are designed to be maintenance-free or quick to replace.

 

The reasonable design and application of railway spring bar fasteners are the basis for ensuring the safe and stable operation of trains, and the corresponding models need to be matched according to the specific line conditions.
