ABSTRACT:
The gooseneck trailer hitch assembly includes a block tube that is fixed to a trailer frame. A top plate is fixed to the block tube. A vertical shaft is connected to the top plate. A steel spherical member is slidably mounted on the vertical shaft. Two rings are clamped to the spherical member and pivotable about the spherical member center. A tower assembly tube receives on of the two rings and is fixed to the rings. A tube positioning member is fixed to the tower assembly. The positioning member includes a wedge surface that contacts a steel ring and moves the tower assembly tube toward a vertical position as the spherical member is moved toward to the top plate. The positioning member also includes a cylindrical surface that engages the steel ring after the tower assembly tube is vertical. A vibration and force damper is provided between the steel ring and the block tube.
