Patent ID: 7484748

Claim:
A steering connection assembly for a vehicle train that includes a first implement towed behind a second implement being towed behind a tow vehicle in a direction of travel, the first implement including a wheel assembly located at a forward end of a frame and supported to swivel about a first vertical axis defined by a vertical steering column located along a central longitudinal axis of the first implement, the steering connection assembly comprising: an elongated tow bar having a forward end opposite a rearward end, the forward end pivotally coupled to the second implement, the rearward end including an elongated opening extending along a length of the tow bar, the rearward end of the tow bar being pivotally coupled to rotate about a second vertical axis at the forward end of the frame of the first implement; a first and a second side retainer member in general parallel to and attached at opposite sides of the elongated tow bar, the first and second retainer members defining the elongated opening therebetween, the first and second retainer members each including a rearward end relative to the direction of travel; a steering arm includes a generally horizontally aligned steering arm member aligned generally perpendicular to a vertically aligned steering arm member; the horizontally aligned steering member includes a forward end having an opening extending therethrough to receive a steering rod member relative to the steering arm; and the steering rod member is attached so that the steering arm is operable to rotate with rotation of the wheel assembly of the first implement about the first vertical axis defined by the steering rod member; wherein a second angle of rotation of the steering arm and attached wheel assembly about the second vertical axis is less than the first angle of rotation of the tow bar about the first vertical axis relative to the central longitudinal axis of the first implement.
