The invention relates to an energy dissipating device suitable to be used as part of a connection device that connects a first car of a multi-car vehicle with a second car of the multi-car vehicle, comprising a plug that has a longitudinal axis and a mandrel that has an opening, whereby the plug is arranged to be moved at least partially through the opening, if a force pointing in the longitudinal axis is applied to the plug, and whereby at least a part of the plug—especially its hull—is deformed, when the plug is at least partially moved through the opening, whereby said hull being at least partially deformed, when the plug is at least partially moved through the opening. The hull is attached to the rod by clamping or fixing with fasteners, preferably with protrusions around the rod and/or at least one plug or nut. The hull is a relatively independent element which can be put over a rod and therefore the hull can be mounted or unmounted subsequently to a rod without influencing the stability or main function of the connection device.

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.

Embodiments relate to a damping system, and in particular a clutch mechanism for an extended travel draft gear having components arranged such that movement of clutch mechanism components transforms kinetic energy into thermal energy via friction, while allowing for an extended length of travel. An arrangement of clutch component geometries, lengths, angles, etc. allows for motion along a longitudinal axis of the clutch mechanism to be damped via energy dissipation.

A dual friction draft gear assembly for a car coupling system of a rail car includes a housing having an internal chamber. One or more friction shoes are disposed within the internal chamber. A first load block has, defines, or otherwise provides a first angled interface with the one or more friction shoes. A second load block has, defines or otherwise provides a second angled interface with the one or more friction shoes.

An assembly that includes a housing with a chamber formed within a bore of the housing. The assembly further includes a center shaft disposed at least partially within the bore of the housing. The chamber includes a backing wedge, a sliding wedge, and a load spring. The sliding wedge is positioned to apply a force onto an angled contact surface of the backing wedge. The sliding wedge is also positioned to apply a frictional force to a rod portion of the center shaft. The load spring is compressed between a contact surface of the chamber and a contact surface of the sliding wedge. The load spring is positioned to apply a compressive force onto the contact surface of sliding wedge toward the angled contact surface of the backing wedge.
