AXLE LOAD DISTRIBUTION CHARACTERISTICS OF A TRIPLE-AXLE TRUCK SUSPENSION SYSTEM

A test of a semitrailer triple-axle suspension, known as the "six-spring" design, revealed that the suspension behaved more like three individual suspended axles rather than a load-equalizing/sharing system. The axle loads were found to vary with axle displacement and chassis attitude, and were often not repeatable. This suspension should therefore, more appropriately be considered a three-axle group rather than a triple axle. (Author/TRRL)
