Patent ·
OSTI ID:6885175
A vehicle air suspension member is described comprising: (a) a hydraulic shock absorber with an axis of extension having an outer body containing an oil filled reservoir, a rod operatively positioned within the reservoir for coaxial reciprocal movement along the axis of extension, the rod extending axially outward from the outer body of the shock absorber; (b) an airspring having an upper retainer with a bore therethrough for receiving therein the rod, the upper retainer being connected to the rod by a resilient mounting means. An airspring piston is axially spaced apart from the upper retainer. A flexible, tubular member is sealingly connected at a first end thereof to the airspring piston and at a second end to the upper retainer to form a sealed pneumatic working cavity. A means is included for changing pressure within the working cavity, a port connecting the working chamber to the means for changing pressure. The airspring piston is attached to the outer body of the hydraulic shock absorber by a means for pivoting the shock absorber relative to the airspring piston during operation of the air suspension.
