  • Trailer with mass restraint
    Patent number: 4369983
    Abstract: In a trailer having two steerable wheels, there is provided a device which, in response to the lateral acceleration of a turn, applies a steering force to the wheels such that the tires generate a side force toward the center of the turn which is equal and opposite to that of the trailer resulting from the acceleration. As a consequence, no net force is exerted on the tow vehicle by the trailer, preserving its handling characteristics. The application is either through a mass on the trailer, or through use of the mass of the trailer itself.
