  • SYNTHETIC ELASTOMERIC AIR SPRING WITHOUT REINFORCING FIBERS
    Publication number: 20230056137
    Abstract: A spring assembly for a vehicle is provided. The spring assembly may include a piston, and a sleeve with a noncircular cross section, the sleeve made from an unreinforced synthetic elastomeric material and being free of reinforcing fibers. The sleeve is coupled with a plurality of end components and defines a deformable pressure vessel, the deformable pressure vessel supplies a support force, and at least one of the end components is the piston.

  • AIR SPRINGS AND METHODS FOR MAKING THE SAME
    Publication number: 20220410645
    Abstract: A spring assembly for a non-rail wheeled or tracked vehicle is provided. The spring assembly includes a piston, and a sleeve with variable thickness. The sleeve is made from an unreinforced synthetic elastomeric material and being free of reinforcing fibers. The sleeve is coupled with a plurality of end components and defines a deformable pressure vessel, and the deformable pressure vessel supplies a support force.

  • Air springs and methods for making the same
    Patent number: 11433726
    Abstract: A method for forming an air spring for a vehicle including a frame coupled to the air spring includes heating an elastomeric base material to a melting point of the elastomeric base material, thereby forming a melted elastomeric base material, forming a sleeve from the melted elastomeric base material, the sleeve being substantially free of textile reinforcing fibers, and engaging the sleeve with end components, the sleeve and the end components defining a deformable pressure vessel, where the deformable pressure vessel supplies a supporting force.
