Abstract
A tandem-axle walking beam suspension is disclosed which uses bushings of novel design in the bores at opposite ends of the walking beams. The cores of the bushings have projecting ends each of which fits between the bifurcated end of one of the pair of axle bracket arms which straddle one end of each walking beam. A removable fastener, such as a nut and bolt is used to connect each projecting bushing core end and its associated bifurcated axle bracket arm. The resulting new system of connecting the equalizer or walking beams to the axle brackets provides easier serviceability of the beam end connections during repair or replacement and by using shims in the connections provides a convenient means of suspension alignment.
