Claims18
An automotive vehicle suspension comprising an axle, means for supporting the vehicle frame on said axle comprising a beam, a pivotal connection between the vehicle frame and one end portion of said beam, and an air spring between the vehicle frame and the other end portion of said beam, said air spring comprising an air spring lobe and a piston, said piston being of inverted, bowl shape having an annular wall terminating at the bottom in a circular peripheral edge, said air spring lobe being connected to the vehicle frame, said piston being mounted on said beam in laterally offset relation to the longitudinal centerline of said beam such that said peripheral edge along one side portion of said piston bears on said beam and said peripheral edge along the other side portion of said piston overhangs one side edge of said beam, and fastening means securing said piston to said beam, said piston having reinforcement ribbing extending inwardly from said annular wall with the bottom surface thereof in the plane of said peripheral edge and bearing on said beam and on said one side edge of said beam.
A piston adapted for use as a component of an air spring in a vehicle suspension, said piston being of inverted, bowl shape having an annular wall terminating at the bottom in a circular peripheral edge, said piston having reinforement ribbing extending inwardly from said annular wall with the bottom surface thereof in the plane of said peripheral edge, said piston having fastening means along one side portion thereof for mounting said piston, said piston being adapted to be mounted by said fastening means on the beam of such vehicle suspension in laterally offset relation to the longitudinal centerline of such beam in a position such that said peripheral edge along said one side portion of said piston bears on such beam and said peripheral edge along the opposite side portion of said piston overhangs one side edge of such beam, and such that the bottom surface of said ribbing bears on such beam and on said one side edge of such beam.
