The present invention is directed to an adjustable trailer hitch that
provides a suspended connection between a tow vehicle and an attached
trailer. The hitch includes a support member that is adapted to be
attached to a tow vehicle and a frame having first and second pivots for
pivotally support a hitch plate, which is operative to connect to a
trailer (e.g., engage a trailer pin). A first air spring has a first end
fixedly connected to the support member and a second end fixedly
connected to the frame. The air spring permits relative movement between
the support member and the frame as well as transmitting towing forces
therebetween. The air spring provides a pliable connection that at least
partially mechanically isolates the trailer and the vehicle from each
other. Instead of acting as a single unit, the vehicle and the trailer
act at least partially independently of each other.
