Rail joint bar with transferred load

Abstract

The present invention is a joint bar wherein the load is transferred from the wheel thread and top of rail onto the wheel flange by means of a ramp built into the inside joint bar. The increasing ramp height ensures that the wheel does not impact the receiving rail. When the wheel has crossed the joint the decreasing ramp action transfers the load back to the wheel thread and onto the top of the rail.

1 . A joint system comprising wherein the joint bars carry the wheel over the joint and prevent impact loads created by the wheel as it traverses the joint. 
   
   
       2 . A joint system as in  claim 1  further comprising where said joint bars carry the wheel over the joint by a ramp. 
   
   
       3 . A joint system as in  claim 2  further comprising where said ramp is on the inside of the rail. 
   
   
       4 . A joint system as in  claim 2  further comprising where said ramp is on the outside of the rail. 
   
   
       5 . A joint system as in  claim 2  further comprising where said ramp is on the inside of the rail built into the inside joint bar. 
   
   
       6 . A joint system as in  claim 2  further comprising where said ramp is on the outside of the rail built into the inside joint bar. 
   
   
       7 . A joint system as in  claim 2  further comprising where said ramps are cast into the joint bars. 
   
   
       8 . A joint system as in  claim 2  further comprising where said ramps are cast as inserts put into the joint assembly.
