Railroad car moving vehicle

摘要

A railroad car moving vehicle has a main frame on which are mounted front and rear axles with steel wheels for engaging the railroad track. Front and rear coupler assemblies have a set of coupler arms with a cross rail member extending between one end of the arms. A coupler is reciprocally mounted on the cross rail member and adapted for coupling with the railroad car. The other ends of the coupler arms are rotatably mounted on a pivot shaft supported by the main frame. The pivot shaft extends between opposed sides of the main frame at its center line. Each set of front and rear coupler arms are mounted on a common pivot shaft such that the horizontal portion of any shock load imparted to one coupler will pass directly through the pivot shaft to the other coupler and not to the main frame. Each end of the pivot member is supported by an isolator assembly. Each isolator assembly is mounted on the main frame and includes a resilient mount. The resilient mount absorbs and dampens any shock load imparted to the coupler assemblies and thus reduces the shock load and vibration on the main frame of the vehicle.
