| 摘要 | A drive device (11) for driving a wheel (7) of an electrically powered vehicle having an electric machine (12) and a transmission unit. The transmission unit has a spur gear transmission (14) and a planetary transmission (13) which, when viewed in the direction of the flow of force during a traction operation, is positioned on the output side of the electric machine (12) in the sequence of the planetary transmission (13) and then the spur gear transmission (14). | ||

| 主权项 | 1. A drive device (11) for driving a wheel (7) of an electrically powered vehicle, the drive device including a housing and comprising: an electric machine (12), and a transmission unit, the transmission unit having a spur gear transmission (14) and a planetary transmission (13) which, when viewed in a direction of a flow of force during a traction operation, being positioned on an output side of the electric machine (12) in a sequential order of the planetary transmission (13) and then the spur gear transmission (14), the planetary transmission (13) and the spur gear transmission (14) having mating helical gears, and the housing of the drive device (11) being directly connected and integrated into a trailing arm of an axle (1), adjacent a connection point of the drive device with the trailing arm, so as to lower an unsuspended mass of the drive device (11). | ||
