ABSTRACT:
Trailer hitch apparatus including dampening mechanisms to simultaneously dampen vibration and shock in a longitudinal direction and vertical direction. The apparatus consists of a hollow draw bar tube capable of being removably coupled to a vehicle mounted receiving tube. The draw bar tube is adapted to move longitudinally relative to the receiving tube while a biasing means within the draw bar tube provide dampening of shock and vibration in the longitudinal movement. The apparatus further has a ball hitch assembly carried by a transverse support bar attached to an outer portion of the draw bar tube. The ball hitch assembly is biased against vertical movement thereby dampening shock and vibration in the vertical direction.
