Title: TRANSMISSION DEVICE AND ELECTRIC DRIVE UNIT COMPRISING AT LEAST ONE ELECTRIC MACHINE AND THE TRANSMISSION DEVICE
Abstract:
The invention relates to a transmission device (2) which has at least one first planetary drive (6), a second planetary drive (8), a hollow shaft, and a shaft (15) which sits concentrically in the hollow shaft and can be rotated relative to the hollow shaft. The first planetary drive (6) is made at least of a first sun gear (11) and first planet gears (12) which mesh with the first sun gear (11); the second planetary drive (8) has second planet gears (35) which mesh with the second sun gear (33); the first planet gears (12) and the second planet gears (35) are arranged at a radial distance from a common rotational axis for the hollow shaft and the shaft; a portion of the shaft protrudes axially from an end of the hollow shaft, and the first sun gear (11) thereby sits on the portion of the shaft; and the second sun gear (33) sits on the hollow shaft coaxially to the first sun gear.
