Abstract
A trailer hitch assembly having a connecting arm disposed within a sleeve and pivotally coupled within the sleeve by a bolt. A tongue at the distal end of the arm rests on one or more air cushions which provide damping or shock absorption to the coupled arm and sleeve during travel. The air cushions are mounted between the tongue and a cross brace of a trailer frame assembly. A hitch coupling is included at a distal end of the arm for engaging a hitch on a towing vehicle. Inflation or deflation of the air cushions allows adjustment of the amount of shock absorption according to the trailer load or road surface conditions.
