The invention relates to a transmission arrangement (10) with a first planetary gear stage (18) and with a second planetary gear stage (20). The transmission arrangement (10) is driven by a rotor (14) of an electric machine (12). The first planetary gear stage (18) comprises a first sun gear (40), and the second planetary gear stage (20) comprises a second sun gear (42). Stepped planet gears (28, 34) of the first planetary gear stage (18) mesh with the first sun gear (40), whereas planet gears (48, 50) of the second planetary gear stage (20) mesh with the second sun gear (42). In the transmission arrangement (10) according to the invention, the first sun gear (40) of the first planetary gear stage (18) is coupled to the second sun gear (42) of the second planetary gear stage (20) via a coupling shaft (26), or alternatively, a planetary carrier (44) of the first planetary gear stage (18), on which the stepped planet gears (28, 34) of the first planetary gear stage (18) are held, is connected to a second internal gear (58) of the second planetary gear stage (20), with which the planet gears (48, 50) of the second planetary gear stage (20) mesh.
