| Abstract: | Current limitators have faults in structure and are hard to maintain or to play their own roles well.Through the research and development of a new type the tongue rail temperature stress-strain expansion joint for high-speed turnouts,instantaneous additional force elasticity on the steel rail is eliminated,and the distortion and direction change of tongue rail are reduced.Therefore,the function of limitators is maximized,with an easy maintenance. |
