Shock absorbing trailer hitch
Abstract:
A shock absorbing trailer hitch generally includes a socket adapted to lock onto a ball connected to the towing vehicle. The socket is connected to a lower support member which supports the bottom of a shock absorbing assembly. An inner tube extends up from the socket and lower tube through the shock absorbing assembly. The upper portion of the shock absorbing assembly is connected to an upper support member that is connected to the towed vehicle. A bearing is secured to the upper tube that slidably but non-rotatably receives the upper portion of the inner tube. The shock absorbing assembly includes rubber springs that absorb the forces experienced by the trailer hitch.
