Planetary gear for transmitting a driving torque in a vehicle, and drive unit comprising the planetary gear

摘要

A planetary gear and a drive unit having the planetary gear, the planetary gear being characterized by very good integratability. For this purpose, a planetary gear (5) for transmitting a drive torque in a vehicle is proposed, having a first sun wheel attachment (12a) and a second sun wheel attachment (12b), each of the sun wheel attachments (12a, b) being coupled to a shaft (2a, b) in a rotationally fixed manner, and the sun wheel attachments (12a, b) being rotatable relative to one another, and the sun wheel attachments (12a, b) being situated in an overlapping area (11), overlapping in the radial direction.

主权项

1. A drive unit comprising:
a planetary gear for transmitting a drive torque in a vehicle; and at least one electric motor for providing the drive torque; a superposition gear; and an additional electric motor, the superposition gear or the additional electric motor being situated coaxially with respect to the shafts, the planetary gear comprising:
a first sun wheel device and having a second sun wheel device, each of the first and second sun wheel devices being coupled to a shaft in a rotationally fixed manner, and the first and second sun wheel devices being rotatable relative to one another, the first and second sun wheel devices being situated in an overlapping area so that the first sun wheel device is radially interior or exterior to the second sun wheel device in the overlapping area.
