摘要： A railroad car draft gear is provided which includes a housing. The housing is a unitary structure, having an open end and a closed end. Compressible spring elements are located inside the housing, with an end of the spring element located against the interior side of the closed end. A friction assembly is also located within the housing, near the open end. The friction assembly provides energy absorption during compression cycles. The spring element restores the friction assembly to its fully extended position after a compression event.

摘要： A car coupling system for a rail vehicle includes a draft sill, and a crash energy management system disposed within the draft sill. The crash energy management system includes a first end plate, a second end plate, and a central tube disposed between the first end plate and the second end plate. The central tube is configured to deform in response to a force exerted into the car coupling system that exceeds a predetermined force threshold. Deformation of the central tube attenuates at least a portion of the force.

摘要： A car coupling system for a rail vehicle includes a first crash energy management system disposed within a draft sill. The first crash energy management system includes a first end plate, a second end plate, and a first central tube disposed between the first end plate and the second end plate. A second crash energy management system is also disposed within the draft sill. The second crash energy management system includes a third end plate, a fourth end plate, and a second central tube disposed between the third end plate and the fourth end plate.

摘要： 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.
