  • Patent number: 4405147
    Abstract: A steering device for steering a spaced axle trailer includes a pair of pivots connecting a tongue to a frame of the trailer. The steering device includes a primary arm pivotally connected to the trailer frame. The primary arm is coupled to pivotal spindle mechanisms on which the front trailer wheels are mounted to translate pivotal movement of the primary arm to the spindles, causing steering of the trailer. A mechanical surge brake device is connected to the tongue. A laterally movable element of the surge brake mechanism is attached to a hitch socket that fits over a hitch ball attached to a tow vehicle, so that the distance between the tow vehicle and the trailer is decreased slightly when the brakes of the tow vehicle are applied.
