A device () for driving working equipment () which can be connected to an agricultural commercial vehicle. The commercial vehicle has a combustion engine () and a generator () which can be driven by the combustion engine (). The commercial vehicle and/or the working equipment () have at least a hydraulic pump (), for the supply of a hydraulic working circuit (), and a mechanical connection (), for driving the working equipment (). At least one hydraulic pump () and/or the mechanical connection () can be driven electrically and/or mechanically, and can be driven with a controllable rotational speed by way of the power branching.

Device for driving working equipment of a commercial vehicle

An apparatus for adjusting the power transfer capabilities of two, shifting elements, by way of which output torque of a transmission of a vehicle can be conducted in a direction transverse to the longitudinal axis of the vehicle to driving wheels of a drivable vehicle axle with the inherent degrees of apportionment as conducted in relationship to the power transfer capability of the shifting elements. Each shifting element has an electric motor; a transmission operationally connected with the electric motor; and placed between the shifting element and the transmission apparatus, a drive converter apparatus, by way of which rotationally directed drive of the electric motors is respectively transformed into a translational activation motion for the control of the shifting elements. The drive converter apparatuses respectively possess a first drive element and a second drive element of which one drive element, converse to the other drive element, is of translational movement.

Apparatus for the adjustment capability of two frictional shifting components

An automatic transmission () is described, having a variator () that comprises at least two conical disk sets (), such that a wrap-around element () is guided via the conical disk sets () for torque transmission with continuous variation of the transmission ratio. In this, the arrangement of the rotation axes of two conical disks of at least one conical disk set relative to one another can be varied.
