<p>A friction cushioning mechanism for draft gear of the combination type including a housing defining an inner or rear chamber in which is mounted a cushioning mechanism that may selectively be of the hydraulic or steel or rubber spring types, and an outer or front chamber in which is mounted a friction mechanism of the type disclosed in U.S. Pat. No. 2,916,163, in which the side edge lugs of the friction mechanism inner fixed friction plates, that key such plates to the housing against movement longitudinally of the housing, are specially formed to resist tendencies of such fixed plates to rock outwardly of the housing under laterally acting force concentrations applied to same during the early part of the draft gear closure stroke, and to avoid deformation of the housing ribs they engage that would introduce looseness in the fit of the friction mechanism parts and consequent reduction in useful life of the gear.</p> |
