Spur gears of the gear set may engage with a toothing which is non-rotatably connected to the output shaft. In known oil guide devices, oil lubrication of the gear set may be achieved through a transverse hole in the output shaft. This weakens the output shaft. Summary of the invention

[0003] The object of the present invention is to provide an improved oil guide device.

[0004] This object is achieved by an oil-conducting component for an oil-conducting device, which comprises the features of claim 1. Advantageous embodiments are subject matter of the dependent claims.

One of the first chamber and the second chamber may be annular.

[0006] The outer side of the second output shaft is in fluid communication with the inner space of the second output shaft via the shaft passage. The shaft passage may be formed in the second output shaft. The shaft passage may extend in the radial direction of the second output shaft. The shaft passage may be formed as a hole. A plurality of shaft passages may be provided. The shaft passages may be evenly distributed in the circumferential direction.

[0007] The oil guiding component is configured so that it can be rotationally fixedly connected to the fixed component. The oil guiding component may be at least partially rotationally symmetrical.

The oil guide component 80 includes a first chamber 81 and a second chamber 82 .

[0048] The first chamber 81 is fluidly connected to the second chamber 82 via a connecting passage 83. The oil guide member 80 is arranged in the fixed part 60 and is rotationally fixedly connected to the fixed part 60. The oil guide member 80 is fluidly connected to the main oil gallery 90 via the first chamber 81.

The oil gallery is formed as an annular gap. As a result, oil guidance can be carried out in a simple manner. In particular, in the case of the oil guide device of the present embodiment, oil lubrication of the first gear set can be achieved without radial holes in the first output shaft 5.

[0049] Further details of the oil guide device are described below.

[0050] The second output shaft 6 is rotatably supported in the fixed component 60 by the first bearing 42. The first output shaft 5 extends in sections in the axial direction in the second output shaft 6 and is rotatably supported in the second output shaft 6 by the bearing 41. The first planet carrier 12 extends in multiple regions in the axial direction in the second output shaft 6. The first output shaft 5 extends through the first planet carrier 12. The first planet carrier 12 is non-rotatably connected to the first output shaft 5 by the take-up gear. The first planet carrier 12 is rotatably supported on the second output shaft 6 by the bearing 40 and by the first axial bearing 45. The first planet carrier 12 is rotatably supported on the first sun gear 11 of the first planetary gear set 10 by the second axial bearing 46. The first output shaft 5, the second output shaft 6, the first sun gear 11, the first planet carrier 12 and the oil guide component 80 are coaxially arranged with each other.

[0051] The first chamber 81 of the oil guide member 80 is open toward the outside in the radial direction. The second chamber 82 of the oil guide member 80 is open toward the inside in the radial direction. The first chamber 81 is placed outside the second chamber 82 in the radial direction and is aligned with the second chamber 82 so that the first chamber 81 overlaps with the second chamber 82 in the axial direction.

[0052] The first chamber 81 is disposed between two grooves on the outer peripheral surface of the oil guide member 80. In each of the two grooves, an O-ring seal is disposed. The O-ring seals each abut against the fixing member 60. Therefore, the first chamber 81 is Figure 1 Seal to the left and right sides towards the outside.

[0053] Arrange in Figure 1The first end portion on the right side of the oil guide member 80, at which the first chamber 81 is arranged, includes an outer periphery having a smaller diameter than the outer periphery of the second end portion located opposite in the axial direction. This configuration serves as an insertion aid for inserting the oil guide member 80 into the fixing member 60. Another groove having another O-ring seal is placed on the second end region.

[0054] The second chamber 82 is placed between the two cylindrical annular surfaces on the inner circumferential surface. A rectangular ring is arranged on each inner circumferential surface. The rectangular ring is arranged on the oil guide member 80 to be fixed in rotation and abuts against the groove on the outer circumference of the second output shaft 6. Therefore, the second chamber 82 is Figure 1 Seal to the right and left sides towards the outside.

[0055] The second output shaft 6 can rotate relative to the oil guide member 80. Figure 1 A slight leakage occurs on the rectangular ring on the left side of the middle part. On the left side of the rectangular ring on the left side, the radial shaft sealing ring is arranged on a cylindrical receiving surface on the inner periphery of the oil guide member 80. The cylindrical receiving surface includes a groove in the circumferential direction for accommodating the radial shaft sealing ring. Between the radial shaft sealing ring and the rectangular ring on the left side, a drain hole for preventing oil accumulation is provided, and the drain hole is arranged so that the radial shaft sealing ring is sufficiently supplied with oil.

[0056] In addition, Figure 1 A slight leakage occurs on the rectangular ring on the right side, which is used to lubricate the first bearing 42 of the second output shaft 6 with oil.

[0057] The second chamber 82 is fluidly connected to the shaft passage 91. Through the shaft passage 91, the outer side of the second output shaft 6 is fluidly connected to the inner space of the second output shaft 6 at the position of the second chamber 82. Therefore, the main oil gallery 90 is fluidly connected to the shaft passage 91 via the oil guide member 80.

[0058] The oil passage 92 of the first gear set is formed by the annular gap between the first output shaft 5 and the second output shaft 6. The shaft passage 91 leads to the oil passage 92 of the first gear set. The oil passage 92 for the first gear set guides the oil to the bearing 41 of the first output shaft 5. The first output shaft 5 is hollow and closed by a plug. In this respect, no oil can flow out of the bearing 41 of the first output shaft 5 through the first output shaft 5. The second output shaft 6 is not hollow. In this respect, no oil can flow out of the bearing 41 of the first output shaft 5 through the second output shaft 6.

The recesses are formed by holes. The recesses are arranged opposite to each other. The recesses are centered relative to the bearing for the first spur gear (in this example, the first planetary gear 14). Via the recesses, the bearing of the first spur gear of the first gear set is lubricated.

[0062] The oil passage 94 for the first spur gear is formed by the annular gap between the first output shaft 5 and the first bracket. The oil passage 94 for the first spur gear is fluidly connected to the end of the oil passage 92 for the first gear set. The oil passage 94 for the first spur gear includes a bearing seat for the second axial bearing 46 of the first bracket and lubricates the bearing. The oil passage 94 for the first spur gear is configured such that oil is conducted to the first spur gear via the second axial bearing 46. In particular, the oil passage 94 for the first spur gear is fluidly connected to the first spur gear.

[0063] In particular, the oil passage 92 for the first gear set branches into the oil passage 93 for the first bolt and enters into the oil passage 94 for the first spur gear.
