The railway rubber pad is also called rubber track bed damping pads, railway track pads, and rubber rail pads. Installed between the steel rail and concrete sleepers, it plays a key role in the rail fastening system. The product structure of the railway rubber pad is a long cushion with a nail post structure on one side, and its flat plate part is composed of fabric-reinforced rubber.
The rubber track bed damping pad plays the role of vibration isolation and belongs to the continuous support structure. Its typical laying and installation method is that the rubber rail pad uses the whole track bed board as a vibration unit. It has the characteristics of large mass and small vibration amplitude, good vibration isolation performance, excellent fatigue resistance and easy installation and usage.
The Longhua Railway Rubber Pad is designed with several key characteristics that make it an essential component of railway track structures:
·Superior Vibration Isolation:
It offers excellent vibration isolation performance with a large mass and small vibration amplitude, effectively reducing track vibrations caused by passing trains.
·Exceptional Durability:
The rubber rail pad is resistant to deformation or breakage across a wide range of temperatures, thanks to its outstanding elasticity, shock absorption, abrasion resistance, and thermal stability.
·Long Service Life and Low Maintenance:
With its long-lasting performance, the rubber pad significantly reduces maintenance and replacement costs, providing substantial savings over time.
·Versatile Compatibility:
Available in a wide range of models and specifications, the railway rubber pad can be tailored to meet specific technical requirements. It is compatible with various types of sleepers, as well as synthetic sleepers, wooden sleepers, and concrete sleepers.
·Other Key Advantages:
The rubber rail pad also offers excellent shock resistance, thermal insulation, wear resistance, and high strength, and is easy to install, ensuring reliable performance and minimal downtime.
