Abstract

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 able to be driven by the torque of the primary drive element. The power-split axle drive includes a power-splitting transmission. The power-splitting transmission via a first gear set is 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 via a first switching element is able to be connected to the power-splitting transmission.
