Abstract
A drive device (1) for driving a wheel (2) of a spring strut axle for an electrically driven vehicle. The drive device has an electric machine (3) and a transmission unit, and the transmission unit has a spur gear transmission (5) and a planetary transmission (4) which, viewed in the direction of the flow of force in traction operation, is positioned at the output side of the electric machine (3) in the sequence of from the electric machine (3) to the planetary transmission (4) and then to the spur gear transmission (5).
