Abstract

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.
