Importance of Spring Clips in railway tracks
2021-09-08
The Clip fastener consists of Spring Clip,baffle,nylon seat and flat washer.Its function is to fix the rail on the rail sleeper,keep the gauge and prevent the rail relative to the sleeper horizontal and longitudinal movement. Pressure of elastic fasteners fasteners is the key to play,it article according to the elastic bending and twist deformation,buckle work pressure effect on the orbit,has effectively guarantee the rail on the middle of the connection,try to keep track of sex,blocked rail relativity in sleeper transverse longitudinal move,ensure safe guard all normal,thus ensure rail car driving safety. In addition,because the train wheel and rail contact is a stiffness contact,so it is difficult to avoid vibration,and the unique elastic structure of the elastic bar makes it also has the digestion and absorption of the impact kinetic energy caused by the car,so as to achieve the effect of shock absorption.The elastic bar works under the constantly changing ground stress,and it bears several functions such as bending,twisting,fatigue and erosion.When the vehicle is under the ground,it also bears very high instantaneous impact load,so the characteristics of the elastic bar are very strict.
