Zusammenfassung:A transmission unit for a driven vehicle wheel comprising an input shaft having a pinion and an output shaft having a ring gear which are parallel so that the input and the output shafts can move transverse relative to one another. At least one planetary gearwheel engages the pinion and the ring gear and is supported by a planetary carrier such that the carrier, the pinion and the ring gear are coaxial with one another. A second carrier is supported coaxial with the ring gear such that the planetary gearwheel is axially arranged between the first and second carriers. The transmission unit enables transverse decoupling between the input and the output, and transmission of large torques. The transmission unit decouples wheel-hub motors from the wheel suspension, in relation to deflection movement of the driven wheel, which facilitates the reduction of the unsprung masses of a wheel-hub drive.
