Running gear for road transport vehicles

The design requirements for commercial and road transport vehicle suspensions are more critical than for any car, even a racing car, because the suspension cannot be tuned for its optimum effectiveness at one load or over a narrow range of loadings. For commercial vehicles, the range of operational loading is from about 25% of maximum load right up to (and through) maximum load. The problems arising from this type of operation and the design improvements that solve these problems (and continually improve commercial vehicle running gear) cover all aspects of the suspensions, axles, brakes, wheels and tyres and the mounting and interconnection. Gradual improvements in bridge and road design and construction and economic evaluation of the overall costs to the community have gradually increased the maximum allowable axle and gross loadings, thus promoting further developments in commercial vehicle running gear. "safety" requirements (some of possible doubtful effectiveness) have been among other problems which commercial vehicle engineers have had to solve. This paper comments upon the variety of suspension and configurations, as well as axles, brakes, wheels and tyres and refers to the solution of some problems, and mentions some of the current problems and possible future developments.
