Abstract
An air spring system adapted to be mounted on a vehicle for absorbing road shocks exerted on the vehicle and for maintaining the vehicle body level with respect to the axles. The air spring includes an end plate and a piston sealingly connected to the open ends of a flexible elastomeric sleeve to form a pressurized fluid chamber therebetween. The flexible elastomeric sleeve rolls over the piston to allow for expansion and contraction of the chamber during shocks. A height sensor is positioned between the sleeve and the piston and in some embodiments includes elements that are molded or embedded within the sleeve and/or piston or both.
