  • Patent number: 7004877
    Abstract: In a variable speed transmission arrangement including an infinitely variable drive having two toroidal input and toroidal output traction wheels with a central shaft connected for rotation with an input traction wheel and extending through the output and the other toroidal input traction wheel and being connected to a planet carrier of a planetary summing gear set while the toroidal traction output wheel is connected, by way of a hollow shaft receiving the central shaft, to the sun wheel of the planetary summing gear set, and the other toroidal traction input wheel is directly connected to the planet carrier by way of a rotational interlocking means rotationally interlocking the planet carrier and the other toroidal traction input wheel, but permitting relative axial movement to facilitate assembly.

  • Patent number: 6991580
    Abstract: A toroidal variable-speed drive unit includes at least one axial offset transmission, at least one actuating member, pivotable supporting journals, and rollers arranged on the pivotable supporting journals which are coupled to one another by the at least one axial offset transmission and can be supported on the at least one actuating member, wherein the rollers are arranged between the actuating member and the at least one axial offset transmission.

  • Patent number: 6855086
    Abstract: A motor vehicle transmission includes a toroidal variable-speed drive unit. The drive unit includes at least an input shaft, a hollow shaft, two driving discs, and a driven disc. The two driving discs are connected fixedly in terms of rotation to one another with the input shaft. The driven disc is connected fixedly in terms of rotation to the hollow shaft arranged concentrically to the input shaft. The hollow shaft is supported axially, at least in one direction, with respect to a transmission case by a bearing.
