Abstract

A turnable pneumatic suspension system is provided wherein proper air flow to the diaphragm is ensured through a charging route that is maintained in a securely sealed condition and which includes a nonrotatable point of attachment to a remote pressurization device. The pneumatic suspension system includes an air spring and a damper in combination, mounted to rotate relative to a vehicle with a dynamic seal provided between a nonrotatable seal ring and mating components of the air spring facilitating rotation of the suspension module while the entrance to the air charging route of the suspension module remains stationary.
