What is the function of Rail Rubber Pads?
Rail rubber pads function to absorb and dampen vibrations and shocks from trains, which protects the rails and concrete sleepers from deterioration. They also help extend the life of the track, reduce noise, improve passenger comfort, and provide electrical insulation.
| Rubber Rail Pad | ||
| Technical Parameter | Unit | Value |
| Stiffness | KN | 90-130 |
| Hardness Shore A | ℃ | 72-80 degree |
| Electronic Resistance | Ω | ≥ 106 |
| Tensile Strength before Aging | Mpa | ≥12.5 |
| Elongation before Aging | % | ≥250 |
Key functions of Railway Rubber Pad
- Vibration and shock absorption: Rubber pads act as a cushion between the rail and the sleeper, absorbing the high-frequency forces and impacts generated by moving trains. This reduces stress on the track structure.
- Protection of components: By dampening vibrations, the pads help prevent the cracking and deterioration of concrete sleepers and reduce wear on the rails themselves.
- Noise reduction: The pads help to quiet the ride by absorbing noise and vibrations, which improves the experience for passengers.
- Electrical insulation: They prevent electrical signals from the rails from being transmitted to the ground, which is crucial for the safe operation of the railway's signaling system.
- Improved stability and longevity: By providing a more stable and protected foundation, rail pads help extend the service life of the entire track system and reduce maintenance costs.
