Wolfgang Stoff has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8177245
    Abstract: A suspension is provided for non-steered wheels on a motor vehicle body. The suspension includes, but is not limited to a twist-beam rear axle with a Watt linkage. A top rocker arm of the Watt linkage is mounted on the motor vehicle body. The Watt linkage prevents the motor vehicle from oversteering during cornering. The damping bushes can be disconnected in part from wheel-guiding functions as the Watt linkage performs a major part of the wheel guiding functions, which leaves some freedom for designing the characteristics so as to significantly increase motoring comfort.

  • Publication number: 20110309593
    Abstract: A Watt's linkage for the movable connection of two machine parts, in particular a vehicle axle and a vehicle body, includes, but is not limited to two rods, whose ends facing away from one another engage on a first of the machine parts, and a coupling device, which couples the ends of the rods facing toward one another to one another, and is linked on the second machine part. The coupling device includes, but is not limited to two levers pivotable around fixed pivot axes on the second machine part. A first engagement point of the levers is connected in each case to one of the ends of the rods facing toward one another, and second engagement points of the levers are connected to one another by a coupling body, which forces a pivot movement in opposite directions of each of the two levers around their pivot axes.
