Abstract
A multispeed spur gear transmission is provided with a planetary gear stage. The multispeed spur gear transmission includes, but is not limited to a spur gear pairing for each gear, a clutch bell with clutch device for coupling a transmission input to a motor output shaft, at least one transmission drive shaft and a transmission output shaft for receiving the spur gear pairings of the gears and a transmission output with an output gear on the transmission output shaft. Between the clutch bell and the transmission input the planetary gear stage is arranged, whose planetary gear cage includes, but is not limited to a spur gear rim that meshes with at least one first spur gear of a rotor shaft of an electrodynamic device.
Claims10
A planetary gear stage of a multispeed spur gear transmission, comprising:
- a first spur gear and a second spur gear forming a pairing for each gear of the multispeed spur gear transmission;
- a clutch bell with a clutch device configured for coupling a transmission input to a motor output shaft;
- a transmission drive shaft and a transmission output shaft configured for receiving the pairing for each gear;
- and
- a transmission output with an output gear on the transmission output shaft;
- a planetary gear cage between the clutch bell and the transmission input the planetary gear stage, the planetary gear cage comprising a spur gear rim that meshes with the first spur gear of a rotor shaft of an electrodynamic device.
