摘要： A railcar energy absorption/coupling system including a cushioning assembly arranged in operable combination with a coupler and a yoke. The cushioning assembly is positioned in a draft pocket defined by a draft sill on a railcar between the front and rear stops. The yoke consists of a back wall along with top and bottom walls which are joined to and axially extending from the back wall toward a forward end of the cushioning assembly. The back wall of the yoke is disposed to contact the rear end of the cushioning assembly. The top and bottom walls of the yoke are operably coupled to a shank portion of the coupler toward a forward end of the yoke. The top and bottom walls of the yoke each include stop members which extend in opposed lateral directions from each other and limit draft travel while maximizing buff travel and limit total combined travel of the energy absorption/coupling system. The energy absorption/coupling system has a neutral position, a full buff position disposed a first predetermined distance from the neutral position, and a full draft position disposed a second predetermined distance from the neutral position, with the full buff and full draft positions for the energy absorption coupling system being disposed in opposite directions from the neutral position.

摘要： A railcar yoke for a railcar energy absorption/coupling system. The yoke includes a rigid and elongated top wall joined to and axially extending from a back wall toward an open forward end of the yoke along with a rigid and elongated bottom wall joined to and axially extending from said back wall toward the open forward end of the yoke. The top and bottom walls of the yoke are separated by a distance whereby allowing an energy management system to be disposed therebetween. Each of the top and bottom walls of the yoke have two forward-facing stops thereon and which extend in opposed lateral directions from each other. The forward-facing stops on the top wall of the yoke are arranged in a generally coplanar relationship with the two forward-facing stops on the bottom wall of the yoke.

摘要： 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.

摘要： An energy absorption/coupling system for a railcar including a draft assembly provided toward opposed ends of a centersill on the railcar. Each draft assembly includes a coupler and a draft gear assembly disposed in longitudinally disposed and operable relation relative to each other. The coupler is configured to allow at least 4.5 inches of travel in a single longitudinal direction during operation of the coupler. The draft gear assembly of each draft assembly is configured to consistently and repeatedly withstand up to about 110,000 ft-lbs. of energy imparted to the energy absorption/coupling system at a force level not to exceed 900,000 lbs. over a range of travel of a wedge member in an inward axial direction relative to the housing of at least 4.5 inches. With the present invention disclosure, high level impact forces between rail cars can be absorbed and dissipated while maintaining an overall length of the railcar constant and unchanged. A method for releasably coupling two railcars to each other is also disclosed.

摘要： A constant contact side bearing assembly for a railcar including a housing with wall structure defining a central axis for the side bearing assembly and a multipiece cap. The cap is arranged in operable combination with the housing and includes a movable first member and a movable second member carried by the first member. A spring resiliently urges the cap members toward railcar body structure. The cap members define cooperating angled surfaces therebetween for urging wall structure on the first member and wall structure on the second member into frictional engagement with the wall structure on the housing in response to a vertical load acting on the friction contacting surface on the cap. An apparatus, carried by the cap members, allow the cap members to horizontally slide relative to each other while limiting vertical separation of the cap members relative to each other during operation of the constant contact side bearing assembly.
