A drive arrangement of a working machine includes a differential gear, a first drive unit coupled to a first element of the differential gear, a working machine coupled to a second element of the differential gear, and a second drive unit coupled to a third element of the differential gear. The speed of the second drive unit can be superimposed on a speed that is dependent on the speed of the first drive unit, whereby the first or second drive unit can be driven at a variably adjustable speed. When a switching element is closed, an auxiliary gear stage is load-transmitting and speeds of the first and second drive units are coupled as a function of at least one transmission ratio of the auxiliary gear stage, and when the switching element is open, the auxiliary gear stage is load-free and speeds of the first and second drive units are decoupled.

Drive arrangement of a working machine to be driven with a variably adjustable speed and method for operating the drive arrangement

A transmission for a drive assembly for driving a working machine at a variable speed of rotation having: a first planet gear set to which a first drive unit can be coupled and a second planet gear set which the working machine can be coupled. The first planet gear set and the second planet gear set each having planet gears which are arranged on at least two common planet shafts which are mounted in a planet carrier. The planet carrier is rotatably mounted in a transmission housing and can be driven by a second drive unit. A torque on the planet carrier can be braced against the transmission housing via a brake or locking mechanism or clutch.

Transmission, drive assembly having a transmission, and method for operating the drive assembly

A gearbox for a drive arrangement of a machine for driving the machine with variably adjustable rotational speed, with a first planet gear set, to which a first drive unit can be coupled and a second planet gear set, to which the machine can be coupled. The first planet gear set and the second planet gear set each comprise planet gears arranged on at least two common planet shafts which are mounted in a planet carrier. The planet carrier is rotatably mounted in a gearbox housing and can be driven by a second drive unit.
