Claims14
A coupling element (30), the coupling element (30) comprising:
- an annular body, an inner circumference of the annular body defining an inner toothing, an outer circumference of the annular body defining an outer toothing, a first end region of the annular body in an axial direction defining a recess (32),
- wherein the inner circumference of the annular body at the first end region defines a circumferential groove (31),
- wherein an oil space (33) is defined at the inner circumference of the annular body, the oil space (33) being delimited in the axial direction by a delimiting surface, the circumferential groove (31) at least partially defining the delimiting surface, and
- wherein the oil space (33) is in fluid communication with the recess (32), the recess (32) enabling an oil flow from the oil space (33) in a radial direction.
