Title
(EN) Railroad car coupling system
Abstract
(EN)

A railroad car coupling system including a draft sill with front and rear stops, a coupler along with an energy management assembly for receiving and dissipating external forces experienced by the coupler. A yoke also forms part of the coupling system and is operably coupled to the coupler. The yoke includes top and bottom walls which each include two forward facing stops. A follower is mounted substantially between the top and bottom walls of the yoke for receiving forces experienced by the coupler. The follower is configured with two laterally spaced vertical extensions disposed toward opposed upper corners of the follower and two laterally spaced vertical extensions disposed toward opposed lower corners of the follower. Forward facing surfaces on the follower extensions arc arranged in generally coplanar relationship relative to each other. Rearward facing surfaces on the follower extensions are arranged in generally coplanar relationship with each other and operably engage with the forward facing stops on the yoke to enhance the distribution of forces when the follower engages the front stops on the center sill when the coupling system is in a full draft condition.
