Abstract

A suspension system for a vehicle tandem axle has air springs positioned adjacent the ends of the trailing and lead axles of the tandem axle. Pairs of air springs on each side of the vehicle are pneumatically connected to form a common reservoir. Displacement of the ends of the lead and trailing axles of the tandem axle are averaged to provide a controlling input to air spring pressurization controllers provided for each pair of air springs.
