In the present invention, the final reduction gear is located above the final reduction gear, which has a large diameter and is immersed in oil, and which meshes with the transmission and transfer device side of the final reduction gear, so that a part of the oil scattered by the rotation of the final reduction gear is removed from the final reduction gear. An oil guide rib is arranged to guide the bevel gear toward the bevel gear which is offset in the left-right direction at the rear upper part of the reduction gear, and the oil guide rib is positioned between the lower end of the rib and the bevel gear. Since the oil reservoirs each have an oil reservoir section that receives oil from the ribs and an oil supply section that is adjacent to the lower part of one of the bevel gears, the oil droplets from the final reduction gear are directly sent through the oil guide ribs to the oil reservoir. Since the oil is collected in the oil reservoir and then supplied to the bevel gear via the oil supply section, the oil supply is stable, and
Since oil is collected in the portion of the oil supply portion adjacent to the lower portion of the bevel gear, the gear and its bearings can be lubricated even better.

A plurality of sets of a speed change drive gear 13 and a driven gear 14 are provided, which are always meshed with each other, and a synchronization mechanism 15 is provided which integrates the driven gear 14 with the subshaft 12 and extracts the power of the speed change by a speed change operation. An output gear 16 is attached to the clutch side end of the countershaft 12, and a final reduction gear 17 with a large diameter of the final reduction device 5 meshes with the output gear 16 to transfer the shifted power from the transmission countershaft 12. It is designed to communicate. The final reduction gear 5 is installed so that the final reduction gear 17 substantially coincides with the center of the wheel, and the differential gear 1 is installed at the center of the final reduction gear 17.
8 is integrally mounted and the axle shaft 19 from the differential device 18 is connected to, for example, the front wheel side, so that the vehicle always runs in front wheel drive. Here, as shown in FIG. 2, in the transmission case 9, oil is deposited at the bottom of the part 9a that covers the final reduction gear 17, which has a large diameter and is installed in a lower position.
The final reduction gear 17 and the substantially lower half of the differential gear 18 are inserted so as to be immersed therein.

連結される。 The transfer device 6 and subsequent devices transmit power to, for example, the rear wheels during four-wheel drive, and unlike the final reduction device 5, there is no restriction on the relationship with the wheels, so the central transfer shaft 20 is connected to the final reduction gear 17. A bearing 21 is mounted at one end, and a double angular bearing 22 is mounted at the other end, at a position higher than the center and facing the left and right direction of the vehicle orthogonal thereto.
They are each pivotably supported and rotatably provided. The final reduction gear 1 is connected to this transfer shaft 20.
A transfer gear 23 is rotatably engaged with the transfer gear 7, and a synchronous transfer clutch 24 is provided between the transfer gear and the shafts 23, 20 to connect and disconnect them. On the other hand, the transfer clutch 2 of such a transfer shaft 20
4, an output shaft 8 is rotatably supported by a tapered roller bearing 25 on the side of the extension housing 10 and is installed in the longitudinal direction of the vehicle.
These transfer shafts 20 and output shafts 8 orthogonal to each other
A pair of bevel gears 7 are connected between the drive side bevel gear 7 and the drive side bevel gear 7.
a is separately attached to the bearing 22 side of the transfer shaft 20, and the driven side bevel gear 7b is formed on the output shaft 8 side. The output shaft 8 is further connected to drive, for example, a rear wheel via a propeller shaft (not shown) or the like.

ある。 With this configuration, the engine power of the engine 1 is transmitted from the crankshaft 2 to the transmission 4 via the clutch 3, and the shifted power from the transmission 4 is transmitted to the final reduction gear 5 via the output gear 16. The signal is input to the final reduction gear 17 and transmitted to the front wheels via the differential device 18 and the axle shaft 19, and is also transmitted to the transfer gear 23 of the transfer device 6. Therefore, when the transfer clutch 24 releases and disconnects the transfer gear and the shafts 23 and 20, the transfer gear 23 idles and no longer transmits power, resulting in two-wheel drive driving using only the front wheels. . On the other hand, transfer clutch 2
4 to engage the transfer gear and shaft 23,
20, after the power is transmitted to the transfer shaft 20, the direction is changed by the bevel gear 7 and the power is transmitted to the rear wheels via the output shaft 8. In this way, the power is transmitted to the rear wheels by the front and rear wheels. The running takes place.

Driven side bevel gear 7b
An oil reservoir 27 is provided at a portion. The oil guide rib 26 is attached to the transmission case 9 by hanging, and the starting end side is connected to the final reduction gear 17 in order to branch a part of the oil that is scattered toward the transfer gear 23 due to the rotation of the final reduction gear 17.
The direction of the bevel gear 7 over a part of the width of 7, for example 45
It is installed diagonally at an angle of 1.5 degrees, and the lower surface is slanted backwards to divert oil when the vehicle is tilted, such as when exiting a vehicle. As detailed in FIG. 3, the oil reservoir 27 includes an oil reservoir portion 27a that is formed like a saucer with an open top and a closed periphery;
It consists of an oil supply part 27b which is arranged perpendicularly to communicate with this oil reservoir part 27a and is open in two directions around the periphery.
This oil reservoir 27 is attached by bolting from the outside of the transmission case 9, and the oil reservoir 27a is communicated with the lower end of the oil guide rib 26 between the differential gear 18 and the transfer clutch 24, and An oil supply section 27b is positioned immediately below the driven bevel gear 7b to receive oil diverted by the oil supply section 26, and supplies oil to the drive and driven bevel gears 7a, 7b, etc. Incidentally, the oil reservoir 27 is also installed to be inclined like the lower surface of the oil guide rib 26, so that it can be operated even when the vehicle is dismounted.

During four-wheel drive, the final reduction gear 17 and the differential gear 18 are always immersed in oil in the part 9a of the transmission case 9 and rotate, so that they and the final reduction gear 1
7, the output shaft 16, the meshing portions of the transfer gear 23, etc. are lubricated. Further, as the final reduction gear 17 having a large diameter rotates while immersed in oil, a relatively large amount of oil is scattered toward the transfer gear 23, while some oil is guided by the oil guide ribs 26. It is split into two parts. In other words, the oil that reaches the transfer gear 23 as it is is transferred to the transfer gear 23, its left and right bearings 21, and the transfer clutch 2.
Supplied to 4th class. On the other hand, the oil guide rib 26
The oil diverted by the oil reservoir 27 is received by the oil reservoir 27a and collected to ensure a predetermined oil level, and the oil is collected in the oil supply part 27b to the driven bevel gear 2.
Since the bevel gear 7b dams up the oil and becomes immersed in it, the drive bevel gear 7a that meshes with it is supplied with a large amount of oil, and the bevel gears 7a, 7b and the bearings 22, 25
is sufficiently lubricated. The oil after lubricating the bevel gears 7a, 7b, etc. immediately returns to the final reduction gear 17 below by its own weight.

As described above, according to the present invention, continuous splashes of oil from the final reduction gear 17 are directed to the oil reservoir 27 of the oil reservoir 27 via the oil guide ribs 26.
Once a predetermined amount is stored in the oil supply section 27
Since the portions of the pair of bevel gears 7 that are offset in the left-right direction at the upper rear side with respect to the final reduction gear 17 are supplied with oil through the terminal b, the oil supply is performed stably. In other words, the lower part of one of the bevel gears 7 comes close to the oil supply portion 27b of the oil reservoir 27 to dam and stir the oil, which improves the quality of the oil. The bearing parts are very well lubricated, and the overall structure is simple.
