Abstract
An equalized suspension system is provided for the truck of a truck-trailer combination of the tandem axle type. The suspension on each side of the vehicle includes independent semi-elliptic leaf springs mounted in tandem relationship one behind the other, and which are respectively connected at their midpoint to the forward and rearward axles. The remote ends of each spring are supported in rolling contact with respective roller assemblies housed by respective brackets which, in turn, are secured to the frame of the truck. An equalizer support bracket is provided between the adjacent ends of each pair of springs and an equalizer is pivotally supported within each equalizer support bracket. The adjacent ends of the springs are pivotally attached to shackles which, in turn, are pivotally mounted to the respective equalizers.
