  • Wheel drive having a rotary union
    Patent number: 9643459
    Abstract: A wheel hub drive with a planetary transmission includes a wheel hub rotatably mounted on a fixed component and at least one fluid-carrying passage. The fixed component is configured to receive a tire with a gaseous filling. The at least one fluid-carrying passage extends indirectly as far as the tire through the fixed component in order to regulate the gas pressure in the tire. An annular rotary union defines at least a portion of the at least one fluid-carrying passage and is configured to connect the fixed component fluidically to the tire. The annular rotary union is arranged axially between the fixed component and the rotatably mounted wheel hub.
    Type: Grant

  • Power split gearbox for a motor vehicle
    Patent number: 8678967
    Abstract: A power split gearbox, in particular for a motor vehicle, includes a mechanical power branch and a hydrostatic power branch. The mechanical power branch and hydrostatic power branch, in a parallel arrangement with respect to one another, are in contact with a common drive shaft. The branched power from the mechanical power branch and hydrostatic power branch are combined in a gear drive arranged on an end side. The mechanical power branch has two planetary gear sets with sun gears, planet gears and internal gears. A clutch is arranged on a side of one of the two planetary gear sets. An internal gear is connected to a sun gear shaft by the clutch.
