Abstract
A tag axle assembly including spaced front hanger assemblies for attachment to spaced frame portions of a vehicle, spaced rearwardly extending beam assemblies pivotally mounted on the spaced hanger assemblies, spaced rear hanger assemblies attached to the spaced frame portions of the vehicle, spaced rubber springs attached between the spaced rear hanger assemblies and the rear of the spaced beam assemblies, an axle mounted between the spaced beam assemblies, first and second cross members extending between spaced portions of the vehicle frame, a third cross member extending between portions of the spaced rear hanger assemblies on opposite sides of the vehicle, and spaced plates secured to the spaced frame portions for preventing excess upward movement of the beam assemblies in the event of malfunction of the rubber springs.
Claims25
