41. rame rails 4 Greater stability and control A unique feature to the ReycoGranning AIRGLIDE drive axle air suspension system is the wear towers and wear blocks These time proven components prevent unwanted side to side lateral motion without the use of costly and complex track rods Air Control System A primary subsystem of a ReycoGranning AIRGLIDE drive axle air suspension system is the air control system Depending on the actual system used the air control system will provide the ability to automatically control the amount of air pressure in the air springs thus automatically control the suspension ride height The major components of an automatic air control system consist of an air compressor reservoir tank height control valve and air spring The operation of the system is simple The compressor supplies air to the tank which maintains the air pressure between 95 125 psi Air from the tank is supplied to the height control valve The height control valve supplies air to or depletes air from the air spring via a mechanical linkage based on axle loading The pressure changes in the air spring but the height remains the same thereby giving the optimum ride regardless of load A system with a single height control valve supplies both air springs simultaneously while a dual height control valve system supplies each air spring separately The dual system increases the sensitivity of side to side distributions of axle loading A sch
