  • the present invention relates to a drive arrangement, in particular a hybrid drive arrangement for a motor vehicle, comprising an electric machine and a clutch arrangement, wherein the electric machine is arranged radially outside the clutch arrangement and has a preferably non-rotatably connected to the clutch assembly rotor.
  • a disadvantage of this prior art is that the hydraulic oil is not only used for cooling the rotor, but also for cooling the multi-plate clutch, so that the expected cooling effect on the rotor is minimal. In addition, under heavy load of the clutch even a heat input to the rotor can take place.
  • Object of the present invention is therefore to provide a drive assembly with an electric machine and a clutch assembly, in which a radially arranged outside the clutch assembly rotor of the electric machine is sufficiently cooled even under heavy load on the clutch.
  • a drive arrangement in particular a hybrid drive arrangement for a motor vehicle, provided with an electric machine and a Coupling arrangement, wherein the electric machine is arranged radially outside of the coupling arrangement and having a preferably non-rotatably connected to the coupling order rotor.
  • the invention is based on the idea of providing a coolant guide element which extends at least partially substantially radially and is arranged axially adjacent to the clutch arrangement such that a coolant can be guided axially from radially inward to radially outward at least partially outside the clutch arrangement to the rotor.
  • the coolant guide element arranged axially next to the coupling arrangement makes it possible to guide a coolant from radially inward to radially outward in the direction of the rotor, wherein, as in the prior art, the coolant does not already undergo heat input via components of the coupling arrangement.
  • the arrangement according to the invention has the advantage that the coolant can be conducted directly to the rotor, without first being guided by the various components of the multi-plate clutch. This allows for a simpler design of the clutch assembly as well as a faster provision of the coolant to the rotor.

  • the substantially axial coolant passage section may then advantageously be arranged between the axial section of the outer disc carrier and the rotor.
  • the radial section of the outer plate carrier with a coolant inlet opening, through which the coolant from the substantially radial coolant channel can be guided into a multi-disc clutch interior and / or to provide the axial section of the outer disc carrier with a coolant outlet opening, through the coolant a multi-plate clutch interior in the substantially axial coolant ring channel is feasible. Since in this case additional coolant is supplied to the hydraulic oil present in the clutch interior, which has not come into contact with the elements of the clutch assembly substantially, an improved cooling is achieved on the rotor in this case. Such an embodiment is particularly advantageous when the rotor is mounted directly on the outer disk carrier or the rotor carrier at the same time takes over the function of an outer disk carrier.
  • the coolant outlet opening is formed in the vicinity of the radial portion of the outer disk carrier, so that the registered in the multi-plate clutch interior coolant is removed as possible without contact from the multi-plate clutch interior again.

  • a preferably annular gap can remain between the components, which allows a particularly uniform distribution of coolant along the rotor.
  • the substantially axially disposed coolant channel may comprise a baffle, which preferably cooperates with a preferably radially outwardly extending opening through the rotor carrier, so that coolant from the axial coolant channel section directly the rotor or to the laminated cores of the rotor can be discharged.
