Abstract: 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.

Abstract: Embodiments relate to a one-piece, integrally formed universal backing ring comprising an integrally formed, one piece annular structure having a center opening configured to be translated over a journal of a railcar axle and engage a dust guard and a dust guard fillet of the railcar axle. The annular structure includes an inner contoured surface having a profile that is contoured for a tight surface fit with a complementary surface of the dust guard fillet. The annular structure also includes a dust guard lip which projects over the dust guard fillet and engages the dust guard. The dust guard lip has a length extending generally parallel with an axis of the annular structure, and is configured to provide a mechanical interference fit of the dust guard lip with the dust guard of 0.052-0.1875 inches with a maximum diameter of the dust guard for each Class of railcar axle.

Abstract: Embodiments relate to a railcar damping system configured for placement in a railcar center sill having longitudinally spaced stops defining a center sill pocket. The system includes a damping assembly configured for receiving and dissipating external forces acting on a coupler connected to the damping system. Various embodiments of the damping system include a longitudinally moveable member, at least one stop and at least one follower block. Some embodiments include a housing. The shape, positioning, and configurations of these features allow for differentiated travel between buff and draft movements.
