Transmission Assembly and Drive Unit

A transmission assembly may include a first transmission input shaft and a second transmission input shaft. The first transmission input shaft and the second transmission input shaft are torque-transmittingly coupled to a first planetary transmission. A transmission output shaft of the transmission assembly is also torque-transmittingly coupled to a second planetary transmission. In the power flow, a first spur gear is arranged between the first planetary transmission and the second planetary transmission. In addition, a drive unit for driving a first vehicle axle is proposed, which has a transmission assembly of this type.
