ABSTRACT:
A steering control mechanism greatly reduces the sway of a towed trailer. The steering control mechanism comprises a stabilizer that is mounted between the wagon frame and a kingpin that supports a steering wheel. The stabilizer introduces friction that resists changes in the wagon direction of travel that are set up by changes in the direction of travel of a towing vehicle. One end of the stabilizer is connected to the wagon frame. The other end of the stabilizer is joined to a stabilizer block that in turn is attached to the kingpin. The stabilizer produces friction sufficient to resist transient steering forces exerted on the wagon tongue, while allowing the wagon to turn in response to permanent changes in the direction of travel of the towing vehicle.
