Abstract: A crash energy management system is configured to be disposed within a draft sill of a car coupling system for a rail vehicle. The crash energy management system includes a front sub-assembly including a front end plate, guide legs extending between the front end plate and a front central plate, a front central tube extending between the front end plate and the front central plate, and stop walls coupled to the guide legs. A rear sub-assembly is coupled to the front sub-assembly, and includes a rear end plate, a rear central plate, and a rear central tube extending between the rear end plate and the rear central plate.
Abstract: A draft gear assembly for cushioning buff and draft dynamic impact forces being applied to a center sill member of the railway vehicle during make-up of a train consist and in-track operation of such train consist includes a resilient cushioning member and a friction mechanism both axially mounted within the yoke with the friction mechanism positioned between the front end of the resilient cushioning member and the front coupler follower. A pair of the resilient cushioning members with the friction mechanism mounted therebetween may also be provided.

Abstract: A draft gear assembly for cushioning both buff and draft dynamic impact forces being applied to a center sill member of a railway vehicle includes a housing member closed at one end and open at an opposed end, the housing member having a rear portion adjacent the closed end and a front portion adjacent the open end. At least one compressible elastomeric spring is positioned within the rear portion and has a rear end thereof abutting at least a portion of an inner surface of the closed end. A friction clutch mechanism is also provided in abutting engagement with each of the front end of the compressible elastomeric spring and the coupler shank. The housing member may be provided with a pair of ledge portions disposed intermediate its ends and attachment members disposed on the open end for attaching the housing member directly to the coupler shank.
