Transtion joint for reducing impacted vibration to rail joint by heavy load train

The invention discloses a transition joint for reducing shock vibration at the joints of the steel rails for heavy load vehicles, adding a transition joint at the joint of existing steel rails, able to play a role of connecting two steel rails and prevent vertical dislocation of the joint. And at the same time, it can also play a role of dividing the load of the train wheels, namely a load-sharing method. It is composed of two parts, one is an inside joint and the other one is an outside joint. That is to say, in the thermal-expanding and cold-contracting space at the joint, when the wheel passes through an expansion joint at the joint, there is always some part to bear the wheel weight to ensure the wheel to run stably. When the vehicle runs stably, there is no shock vibration between the wheel and the steel rails, thus improving the safety of vehicles and prolonging the service life of road foundation.
