Abstract
A plastic knuckle pin for a coupler on a railway car which accepts bending fatigue, eliminates rust or corrosion, and reduces the coefficient of friction during opening and closing the coupler. The pin also protects the integrity of the coupler body and the knuckle to reduce coupler maintenance and further reduces the weight of the railway car and facilitates the use of a self-locking feature.
