<p>A STRIKER FOR RAILWAY COUPLER A striker for a railway vehicle comprises a casting, having an endless rib projecting outwardly from each side wall to reinforce a key slot for a draft key. The endless ribs present continuous surfaces for welding the striker to a sill of a railway vehicle. Above and below the endless rib on each side wall are inwardly-displaced side wall sections to inwardly shift the neutral axes of the wall sections for resisting imposed loads, In a second embodiment, weld sites above and below the endless ribs are formed, High-strength load transfer for pull forces is achieved at weld sites at the rear portion of the casting, Load transfer is supplemented by lower-strength weld sites at the forward portion of the casting, Other weld sites are formed along vertical parts of front draft lugs.</p> |
