Abstract
There is an electric railway truck comprising an unsprung third rail collector beam for a swing arm primary suspension. The collector beam and attached current collector is mounted to the truck frame through the use of mounting adapters, links, and elastomeric bushings. Specifically, in the vicinity of the swing arm axle housings, the collector beam is secured to the mounting adapters which, in turn, are suspended below the respective axle housings by the links and accompanying elastomeric bushings. The torsional deflection of the elastomeric bushings permit the links to swing in the longitudinal direction, thereby accommodating the relatively larger angular and longitudinal axle housing motions created by a swing arm primary suspension.
