A power-split axle drive for an agricultural vehicle, including a first additional drive element, a first vehicle axle, a second vehicle axle, and a primary drive element for providing a torque which via a first shaft is able to be transmitted to a primary transmission. The primary transmission is connected to the second vehicle axle, and at least the second vehicle axle via the primary transmission is drivable by the torque of the primary drive element. The power-split axle drive has a power-splitting transmission connected to the second vehicle axle and the primary transmission and via a second shaft is connected to the first vehicle axle. The first additional drive element is able to be connected to the power-splitting transmission, wherein a first switching element is disposed on the second shaft.

Power-split axle drive and agricultural vehicle

A power supply arrangement having an interface for operation of a multi-voltage system of an agricultural vehicle includes a first network segment with a motor generator connected thereto and a second network segment with a lead battery connected thereto. The first network segment has a first voltage level corresponding to a nominal voltage of the lead battery for operation of an electric vehicle components, and the second network segment includes a higher second voltage level for charging the lead battery and providing electric power to an electric load comprising an agricultural implement. The interface forms a voltage source connecting the two network segments and provides an equalization voltage resulting from the two voltage levels in a charging mode and which is bypassed in a motor operating mode.
