A THEORETICAL STUDY OF CONSTANT AREA GAS SPRINGS IN PASSENGER CAR SUSPENSIONS

Gas suspensions are finding increasing use for levelling and ride frequency regulation in passenger cars. Oil or gas pumping types may be used alone or in combination with steel springs. Four distinct kinds of system are identified as needing different optimisation methods. Performance and installation aspects are analysed over a range of vehicle weights and the, sometimes surprising, results are discussed and compared. An evaluation of the effect of such variable rate suspensions on the roll stiffness distribution between axles might be of special interest to designers concerned with handling. Finally, four complete vehicle installations are compared and recommendations made.
