Cooling Oil Conducting Element And Drivetrain Comprising Same
Abstract: The present invention relates to a cooling oil conducting device for rotating components, an annular oil duct (K) running in a radial direction, and cooling oil being feedable from radially inwards and the oil duct (K) being partially open radially outwards, characterised in that a sealing region is provided in a radially outer region of the oil duct (K), in that the sealing region comprises blocking elements (12) and discharge elements (13), in that the blocking elements (12) are arranged radially inside the discharge elements (13) and have at least two apertures (14) in the radial direction, distributed over the circumference, in that discharge ducts (A) which are aligned with the apertures (14) and also inlets (E) which are disposed, in the circumferential direction, between the discharge ducts (A) are formed by the discharge elements (13), and in that an annular duct (R) is provided between the blocking elements (12) and the discharge elements (13) in order to connect the inlets (E) to the discharge ducts (A) or apertures (14). The invention further relates to a drivetrain comprising a cooling oil conducting device of this kind.
