The importance of track clips in railway tracks

With the increase of the axle load of railway locomotives and the increase of train speed, as well as the development of urban rail transit and subway, spring bars, as a key link of track structure, are constantly developing, and their importance is becoming more and more important. countries are concerned.

Our country is a vast country with great differences in climate, transportation conditions and regions. It needs various elastic bars with different performance requirements to meet the requirements of different tracks and different track types. For example, on conventional lines, large buckle pressure and good elasticity are required to meet the needs of heavy-duty and high-speed lines; while in seamless lines of viaduct tracks, in order to reduce the interaction force between rails and bridges, fasteners are required The resistance is small, and the elastic strips are guaranteed to have sufficient elasticity, that is, the rigidity of the elastic strips is low enough to ensure that the buckle pressure loss caused by the compression of the under-rail cushion is small when the train passes, and the fasteners are not loose.

It can be seen that although the spring bar is a small public service device, it is an important part on the track. Because of its large demand, about 7,000 pieces per kilometer, its reliability is directly related to the safety of driving.
