The role of rail clip fasteners in railway tracks

The railway rail is a component that supports the direction of the locomotive and the locomotive, and the rail is fixed on the sleeper of the ballast bed through elastic fasteners.

The buckle part of the elastic fastener is mainly the elastic strip, which generates buckle pressure on the rail through the bending and twisting deformation of the elastic strip, effectively ensuring the reliable connection between the rails for a long time, maintaining the integrity of the rail as much as possible, and preventing the rail from Relative to the vertical and horizontal movement of the sleepers, the gauge is guaranteed to be normal, thereby ensuring the safety of rail vehicles.

In addition, since the contact between the train wheel and the rail is a rigid contact, it is inevitable to generate vibration, and the special elastic structure of the elastic strip can also absorb the impact energy generated when the vehicle passes by, so as to achieve the effect of shock absorption. The elastic strip works under repeated alternating stress. It bears various effects such as bending, torsion, fatigue and corrosion. When the vehicle passes, it also bears a high instantaneous impact load, so the performance requirements for the elastic strip are very strict. .
