Abstract

The proposal relates to an oil guide channel part (1) for installation in a transmission (100), in particular in an automotive transmission, which comprises a guide channel (2) with a receiving opening (11) and a discharge opening (12), which guide channel (2) comprises an oil guide direction (F) from the receiving opening (11) to the discharge opening (12) and a circumferentially closed channel wall (21) perpendicular to the oil guide direction (F), which further comprises at least one oil collecting area (13a) for storing oil guided through the guide channel (2), and which comprises at least one outlet (15a) for oil from the at least one oil collecting area (13a). It is proposed that the at least one oil collecting area (13a) comprises a first reservoir (13), the first reservoir (13) having a first reservoir wall (25) and a first reservoir bottom (24), the guide channel (2) is adjacent to the first reservoir wall (25) of the first reservoir (13), and, viewed in the oil guide direction (F) of the guide channel (2), the first reservoir bottom (24) is arranged between the receiving opening (11) and the discharge opening (12).

Claims

1. An oil guide channel component (1) for assembly into an automobile transmission in a predetermined assembly direction, The oil guide channel component (1) comprises a guide channel (2) having a receiving opening (11) and a discharge opening (12), The guide channel (2) comprises an oil guide direction (F) from the receiving opening (11) to the discharge opening (12), and a channel wall (21) that is closed in the circumferential direction perpendicular to the oil guide direction (F). The oil guide channel component (1) further comprises at least one oil collection area (13a) for storing oil guided through the guide channel (2), The oil guide channel component (1) comprises at least one outlet (15a) for oil from the at least one oil collection area (13a), wherein the at least one oil collection area (13a) includes a first storage tank (13), The first storage tank (13) has a first tank wall (25) and a first tank bottom (24), The guide channel (2) is adjacent to the first tank wall (25) of the first storage tank (13), and the first tank bottom (24) is positioned between the receiving opening (11) and the discharge opening (12). The first outlet (15) protrudes from the first tank wall (25) above the first tank bottom (24) in the predetermined assembly direction. The oil collection area (13a) of the oil guide channel component (1) includes a second storage tank (14), and the second storage tank (14) has a second tank wall (27) and a second tank bottom (26). The second outlet (16) protrudes from the second tank wall (27) of the second storage tank (14) above the second tank bottom (26) in the predetermined assembly direction. The second storage tank (14) is connected to the first storage tank (13) via a connecting channel (29). The end of the channel wall (21) of the guide channel (2) on the opposite side of the receiving opening (11) protrudes beyond the first tank bottom (24) of the first storage tank (13) and forms a peripheral wall (21a) that defines the discharge opening (12). The edge of the peripheral wall (21a) has a distance from the first tank bottom (24) on the side facing the first storage tank (13), and this distance is smaller than the distance of the edge of the peripheral wall (21a) from the second tank bottom (26) on the side facing the second storage tank (14). An oil guide channel component (1) characterized by the following:

2. The oil guide channel component (1) according to claim 1, characterized in that the oil guide channel component (1) is assembled in the predetermined assembly direction with respect to gravity (G), and the first tank bottom (24) is assembled substantially perpendicular to gravity (G).

3. The oil guide channel component (1) according to claim 1, characterized in that the guide channel (2) is formed in a straight line from the receiving opening (11) to the discharge opening (12).

4. The oil guide channel component (1) according to claim 1, characterized in that the third outlet (19) protrudes from the first tank wall (25) of the first storage tank (13) above the first tank bottom (26) in the predetermined assembly direction and on the side opposite to the first outlet (15).

5. The oil guide channel component (1) according to claim 1, characterized in that the oil guide channel component (1) has a plurality of retaining cams (23) protruding from the oil guide channel component (1) on the opposing side of the oil guide channel component (1), and the oil guide channel component (1) can be installed in the transmission (100) in the predetermined assembly direction by the retaining cams (23).
