  • Control valve for influencing the tire pressure of a vehicle wheel
    Patent number: 4805681
    Abstract: A control valve for increasing or reducing the air pressure in a tire of a vehicle wheel that is to be carried out over a short period of time, has a valve chamber that is connected, on one side, to the interior of the tire and, on the other side, to a supply duct. The valve chamber has a space that extends axially through the wheel hub, the interior end of this space being sealed off with respect to an axle part carrying the vehicle wheel. In this space, an automatically closing valve member is arranged that can be controlled into its open position against the interior pressure of the tire by a control piston that is also guided in this space and can be acted upon by a pressure medium. For supplying air to and removing air from the tire, the axle part projects into an axial duct of the control piston with a cylindrical projection that is penetrated by the supply duct.

  • Device for the contactless indirect electrical measurement of the torque at a shaft
    Patent number: 4805466
    Abstract: A device for the contactless indirect electrical measurement of the torque at a shaft utilizing the Matteucci effect in which the shaft is located in an induced magnetic direct-axis field. Upon torsion of the shaft, the change in magnetization in the shaft itself is not measured, but rather a measuring layer applied to the shaft is metrologically detected by the device. In order to avoid disturbing influences from the basic magnetization of the shaft on the measuring layer, a further layer is applied to the shaft, which short-circuits the magnetic flux resulting from the basic magnetization of the shaft, the measuring layer being magnetically decoupled from the inner layer by a highly nonmagnetic layer between the inner, further layer and the measuring layer.

  • Suspension system for rigid vehicle axle
    Patent number: 4802689
    Abstract: The invention relates to an axle suspension means for motor vehicles, wherein the guide means of a rigid axle is constructed so that the latter changes its position in the sense of a positive oblique springing during inward spring stroke movements, and executes no inherent steering movements during one-sided and alternate-side inward and outward spring strokes.
