Design, Application, and Comparative Tests of Trailer Air Suspension Systems

Air suspension systems for highway trailers offer changes in ride characteristics which affect cargo transport, driver comfort, and structural design. These changes have brought about new considerations for those responsible for designing and maintaining highway vehicles, as well as for those concerned with the effects of shock and vibration upon both cargo and operator.

The purpose of this paper is to describe the design principles of Neway Equipment Company 's trailer air suspension, to illustrate certain applications of this suspension system, and to present results of comparative ride tests.

Conclusions are drawn on the effectiveness of road testing, and suggestions are made on an improved approach to ride analysis.
