An accumulator is provided for a vehicle air system including a vehicle frame. A wheel end is spaced from the frame for supporting the vehicle frame on a roadway. A suspension assembly includes a suspension structure. The suspension structure may be a portion of an axle, a stabilizer bar, a control arm, or other suspension components. The suspension structure is interposed between the frame and the wheel end and is movable relative to the vehicle frame in response to the wheel end receiving inputs from the roadway. A fluid chamber forms the accumulator and is defined by a portion of the suspension structure for storing pressurized air. Preferably a valve is disposed within the fluid chamber to protect the valve from the environment. For light vehicle applications where a conventional air pump may be cost prohibitive, a mechanical pump may be connected between the vehicle frame and the suspension assembly. The mechanical pump provides pressurized air to the fluid chamber in response to relative movement between tree suspension assembly and the vehicle frame as the vehicle travels along the roadway.
