  • Patent number: 7338034
    Abstract: An elastomeric spring including an elongated elastomeric body defining a longitudinal axis for the spring and having first and second longitudinal ends. An outer surface of the elastomeric body extends between the first and second ends and has four generally planar sides, with each planar side of the outer surface being disposed to one side of and generally parallel to the longitudinal axis of the spring so as to reduce radial bulging of the spring in all directions when an axial load is applied to the spring. The outer surface of the elastomeric body further includes four angled corner sections extending between the first and second ends of the elastomeric body and disposed a substantially common distance from the longitudinal axis of the spring. One corner section is disposed between any two adjoining sides on the outer surface of the elastomeric body.
