Abstract
A pneumatic proportioning system for heavy-duty vehicle air springs includes an air supply, a height control valve and a solenoid valve in fluid communication with one another and with the air springs of at least one axle/suspension systems of a heavy-duty vehicle. A proportioning means is in fluid communication with the air supply, with the height control valve, with the solenoid valve, with the air springs and with atmosphere and operates to proportion loads between the air springs of the axle/suspension systems when the solenoid valve is activated during operation of the heavy-duty vehicle.
