Introduce The Characteristics Of Type III Clips

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.
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 by elastic fasteners. The fastening part of the elastic fastener is mainly the elastic strip. Through the bending and twisting deformation of the elastic strip, the buckle force is generated to act on the track, which can effectively ensure the reliable connection between the rails for a long time, maintain the integrity of the track as much as possible, and prevent the The vertical and horizontal movement of the rail relative to the sleeper ensures the normal gauge, thereby ensuring the safety of the rail vehicle. 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 very high instantaneous impact load, so the performance requirements for the elastic strip are very strict.
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. On conventional lines, elastic strips with high 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, fastener resistance is required Smaller, and ensure that the elastic strips have sufficient elasticity, that is, ensure that the elastic strips have a sufficiently low rigidity, so as 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 do not loosen.
