Abstract:
A railcar diaphragm is described having a first and a second plate assembly, a bellows assembly, and a spring assembly. The first plate assembly is coupled to a railcar. The second plate assembly is configured to contact another railcar. The bellows is disposed between first and second plate assemblies. The spring assembly includes a leaf spring and a pivot member coupled to the leaf spring. The first and second plate assemblies are coupled through the spring assembly. The spring assembly has a first and a second configuration based on whether the railcar is engaged to another railcar. The spring assembly and the second plate assembly can collectively swivel about a centerpoint associated with the pivot member when the spring assembly is in the second configuration and the railcar is in a curved portion of a track.
