ABSTRACT:
A slackless drawbar system for a railway car in which there is provided an elastomeric pad that absorbs forces during buffing conditions and helps to maintain the slackless nature of the system. The elastomeric pad absorbs forces during lateral and vertical angling and serves to maintain the slackless nature of the system during these conditions. Preloading of the resilient elastomeric pad is provided by means of an adjustable wedge element, which wedge element is adjustably positionable relative to the elastomeric pad by means of a screw shaft and nut, whereby the initial loading of the pad may be achieved to meet any required operating conditions and to accommodate wear and tear.
