Air spring unit

摘要

An improved air spring unit adapted to be employed in modifying suspension systems for a wheeled vehicle having a cantilevered leaf spring assembly. The air spring unit is characterized by a pressurizable air bag disposed in substantial vertical alignment with a live axle, a force dissipating rocker arm having one end portion supported by the air bags, and a second end portion disposed in a supported relationship with a projected end portion of the leaf spring assembly, and a clevis connecting the midportion of the arm to a longitudinal frame member provided for the vehicle, whereby the air bag is employed in juxtaposition with the well of an adjacent wheel, so that increased radial expansion of the bag is facilitated.
