Oilway arrangement for a transmission housing
An oil guidance arrangement for a transmission housing ( 1 ) of a vehicle includes at least one annular oil slinger ( 2 ) for collecting radially outward flowing oil. A guide area ( 3 ) for generating a laminar oil flow is closed in sections and is provided on a circumferential area of the oil slinger ( 2 ). A transmission housing ( 1 ) includes the oil guidance arrangement. The oil slinger ( 2 ) of the oil guidance arrangement is attached to a transmission housing-side centering plate ( 10 ) and surrounds a clutch ( 6 ). By rotation of the clutch ( 6 ), oil is guidable radially outward to the guide area ( 3 ) of the oil slinger ( 2 ).
1. An oil guidance arrangement for a transmission housing ( 1 ) of a vehicle, comprising at least one annular disk-shaped oil slinger ( 2 ) for collecting radially outward flowing oil, wherein the oil slinger ( 2 ) has a guide area ( 3 ) for generating a laminar oil flow, the guide area ( 3 ) closed in sections and having at least one inflow opening ( 4 ) and at least one outflow opening ( 5 ), the guide area ( 3 ) provided on a circumferential area of the oil slinger ( 2 ).
2. The oil guidance arrangement of claim 1 , wherein the guide area ( 3 ) has a turbine blade geometry in a circumferential direction for oil guidance.
3. The oil guidance arrangement of claim 1 , wherein the guide area ( 3 ) is configured such that a radially directed oil flow enters into the guide area ( 3 ) through the inflow opening ( 4 ), the oil in the guide area ( 3 ) is tangentially diverted by the guide area ( 3 ), and an axially aligned oil flow exits the guide area ( 3 ) through the outflow opening ( 5 ).
4. The oil guidance arrangement of claim 1 , wherein the guide area ( 3 ) on the circumferential area of the oil slinger ( 2 ) extends along a circumferential angle of approximately thirty degrees.
5. The oil guidance arrangement of claim 1 , wherein the oil slinger ( 2 ) comprises a plurality of attachment sections across the circumferential area, the plurality of attachment sections configured for attachment on the transmission housing ( 1 ) to mount the oil slinger ( 2 ) to the transmission housing ( 1 ).
6. The oil guidance arrangement of claim 1 , wherein the oil slinger ( 2 ) defines a central recess ( 9 ), the central recess ( 9 ) configured for receipt of a shaft within the transmission housing ( 1 ).
7. A transmission housing, comprising the oil guidance arrangement of claim 1 , wherein the oil slinger ( 2 ) of the oil guidance arrangement is attached to a transmission housing-side centering plate ( 10 ) and radially surrounds a clutch ( 6 ) such that rotation of the clutch ( 6 ) guides oil radially outward to the guide area ( 3 ) of the oil slinger ( 2 ).
8. The transmission housing of claim 7 , wherein the inflow opening ( 4 ) of the guide area ( 3 ) of the oil slinger ( 2 ) is radially aligned with the clutch ( 6 ).
9. The transmission housing of claim 7 , wherein the outflow opening ( 5 ) in the guide area ( 3 ) of the oil slinger ( 2 ) is directed axially towards an interior space of the transmission housing ( 1 ).
