Add an Axle by the Use of an Equalizing Air Suspension 650726
Independent equalizing air suspensions are being added to trucks, tractors, and trailers in order to increase their capacity. That is, independent air suspensions are being combined with standard production suspensions so as to economically produce vehicles with greater versatility. Axle load equalization is obtained by regulating air pressure to the air suspension, which controls the load on the independent axle.
This paper describes the design and application of the independent equalizing air suspension as used by the trucking industry.
