A gearbox assembly, in particular for a wheel drive of a vehicle with a hydrostatic gearbox ( 2 ) having at least one downstream planetary stage ( 3 ), wherein coupling the planetary stage ( 3 ) to the hydrostatic gearbox ( 2 ) is via intermediate gearbox means for speed overlap within the planetary stage ( 3 ), by having, according to a first driving mode, the sun gear ( 3 b) of the single planetary stage ( 3 ) in effective interaction with a ring gear ( 3 a) of the planetary stage ( 3 ) via a first coupling ( 4 ), so that the output speed of the planetary stage ( 3 ) is a linear function of the output speed of the hydrostatic gearbox ( 2 ) and that, according to a second driving mode, the ring gear ( 3 a) is in effective interaction with the hydrostatic gearbox ( 2 ), wherein, at the same time, the sun gear ( 3 b) is in effective interaction with a gearbox input shaft ( 1 ) via a second coupling ( 5 ) so that as a consequence of power distribution, the speeds of the ring gear ( 3 a) and the sun gear ( 3 b) overlap.
