Abstract
A vehicle suspension system has a combination air spring/damper mounted between spaced first and second components of a vehicle. The damper has a fluid cylinder attached to the first vehicle component and a piston rod connected to the second vehicle component. The air spring has a piston and an end plate with an intervening flexible bellows forming an air chamber. The air spring piston is mounted on and surrounds the damper cylinder and the end plate is secured to the second vehicle component, but at a separate location from the attachment of the piston rod to distribute the loading forces at the points of attachment. A flexible sealing sleeve extends between the piston rod and an end plate opening of the air spring through which the piston rod extends. A rigid canister is mounted on the end plate of the air spring and extends about the flexible bellows and has a sealing skirt at a lower end which engages the damper cylinder.
