Heavy Duty Truck Tandem Suspension for On/Off Highway Applications

This paper describes the design, development, and testing of a heavy duty truck tandem suspension intended for vehicles that must operate both on and off the highway.

The notable features of this suspension are a nonlinear spring rate, improved axle vertical travel, the wide span over which the suspension is mounted to the frame, and the ease with which the suspension accommodates different spacings between the tandem axles.
