1. A coupling element (30), comprising:
an internal toothing; and
a cutout (32),
wherein the coupling element (30) is configured for coupling a first gear set and a second gear set of a gearing, the first gear set comprising a first ring gear (15), the coupling element (30) forms the first ring gear (15) on an inner circumference of the coupling element (30) via the internal toothing,
wherein the coupling element (30) is formed in an annular manner, and the cutout (32) is formed at a first end region of the coupling element (30) in an axial direction, and
wherein an oil chamber (33) is formed by the coupling element (30), the cutout (32) enabling an oil flow out of the oil chamber (33) in the axial direction.
