Abstract

An oil duct part includes a conduit with an inlet port and an outlet port. The conduit has an oil conducting direction (F) from the inlet port to the outlet port and has a conduit wall that is closed all around perpendicularly to the oil conducting direction (F). The oil duct part further includes at least one oil collection region for collecting oil conducted through the conduit. The oil duct part also includes at least one drain for oil from the at least one oil collection region. The at least one oil collection region includes a first reservoir having a first reservoir wall and a first reservoir base. The conduit adjoins the reservoir wall of the first reservoir in such a way that the first reservoir base is arranged between the inlet port and the outlet port when viewed in the oil conducting direction (F) of the conduit.

3. The oil duct part ( 1 ) according to claim 1 , wherein one end of the conduit wall ( 21 ) of the conduit ( 2 ) facing away from the inlet port ( 11 ) forms a circumferential wall ( 21 a ) projecting above the first reservoir base ( 24 ) of the first reservoir ( 13 ) and delimiting the outlet port ( 12 ).

4. The oil duct part ( 1 ) according to claim 3 , wherein the oil collection region ( 13 a ) of the oil duct part ( 1 ) comprises a second reservoir ( 14 ), wherein the second reservoir ( 14 ) has a second reservoir wall ( 27 ) and a second reservoir base ( 26 ), wherein the second reservoir ( 14 ) is connected with the first reservoir ( 13 ) via a connection channel ( 29 ), and wherein an edge of the circumferential wall ( 21 a ) on a side facing the first reservoir ( 13 ) has a distance from the first reservoir base ( 24 ) which is less than a distance of the edge of the circumferential wall ( 21 a ) from the second reservoir base ( 26 ) on a side facing the second reservoir ( 14 ).

5. The oil duct part ( 1 ) according to claim 1 , wherein the conduit ( 2 ) is configured in a straight line from the inlet port ( 11 ) to the outlet port ( 12 ).

6. The oil duct part ( 1 ) according to claim 1 , wherein the oil collection region ( 13 a ) of the oil duct part ( 1 ) comprises a second reservoir ( 14 ), wherein the second reservoir ( 14 ) has a second reservoir wall ( 27 ) and a second reservoir base ( 26 ), wherein the second reservoir ( 14 ) is connected with the first reservoir ( 13 ) via a connection channel ( 29 ).

7. The oil duct part according to claim 6 , wherein a second drain ( 16 ) projects from the second reservoir wall ( 27 ) of the second reservoir ( 14 ) in a predetermined installation direction above the second reservoir base ( 26 ).

8. The oil duct part ( 1 ) according to claim 7 , wherein a third drain ( 19 ) projects from the first reservoir wall ( 25 ) of the first reservoir ( 13 ) in the predetermined installation direction above the first reservoir base ( 26 ) on a side opposite the first drain ( 15 ) of the at least one drain ( 15 a ).

9. The oil duct part ( 1 ) according to claim 1 , wherein the oil duct part ( 1 ) comprises a plurality of holder cams ( 23 ) projecting from the oil duct part ( 1 ), via which the oil duct part ( 1 ) can be mounted in a predetermined installation state in the transmission ( 100 ).
