Tag axle suspension system for a dump vehicle

摘要

A tag axle suspension system for use with a dump vehicle and other systems provides weight reduction and enhanced safety and ride quality. In a described embodiment, a tag axle suspension system includes hanger brackets pivotably attached to a vehicle frame. Actuators push rearwardly on the hanger brackets to raise an axle relative to the vehicle frame. The hanger brackets are rigidly attached to a tubular member extending laterally across the vehicle frame. The tubular member is rotatably attached to the vehicle frame.
