The draft gear includes: friction elements; coil spring elements; and elastomer elements. With respect to the friction elements, three groups of friction surfaces are defined each of which create a specific angle with respect to a centerline passing down the center of the draft gear. The elastomer elements are interconnected multiple segmented columns having specific heights and occupying particular volumes with respect to the coil spring elements. Particular hardness and number of segments of the elastomer elements are also defined. |
