Abstract

PURPOSE:To simplify structure and to reduce oil agitation resistance, by a method wherein two chambers are formed in series so that the one end surface of a gear chamber is totally open to an output distribution chamber, and an oil guide is located above a chain driving device in an output distribution chamber. CONSTITUTION:A transfer case 1 is provided at its interior with a gear chamber 3 containing a transmission gear device 2 and an output distribution chamber 5 containing a chain type output distribution device 4 adapted to distribute an output to front and rear wheels. The output distribution chamber 5 is formed in a shape in that it is extended further toward the front output shaft 9 side than a gear chamber 3, and is formed in series so that the one end surface of the gear chamber 3 is wholly open to the output distribution chamber 5. An oil guide 11, adapted to temporarily stow oil, is located in the upper space of a chain transmission device 10 in the output distribution chamber 5. This simplifies a case 1 through elimination of a conventional partition, and causes a decrease in an amount of return oil by means of the oil guide 11, resulting in reduction in agitation resistance of oil.

きわめて大きくなっている。Conventionally, such a transfer case for a four-wheel drive vehicle is disclosed in, for example, Japanese Utility Model Application Publication No. 53-121642. As shown in FIG. 1 of the present application, this device includes a gear chamber 3 that houses a transmission gear device 2 within 1 degree of a transfer case, and a chain type output distribution device 4 that distributes output to front and rear wheels (not shown). An output distribution chamber 5 for housing is provided. Inside the output distribution chamber 5, there is a rear export force shaft 7 arranged coaxially with the input shaft 6, and a counter shaft 8 of the transmission gear device 2 with a predetermined interval therebetween. The front export force axis 9 is located parallel to each of the above axes.
are inserted through the re-output shaft 7.9, and a chain transmission 10 is provided which interlocks and connects these. This chain transmission device 10 consists of a driving sprocket 10a fixed to the rear export force shaft 7, a driven sprocket 10b fixed to the front export force shaft 9, and a chain 710c wrapped around both sprockets 10a, 10b. Further, the gear chamber 3 and the output distribution chamber 5 are completely partitioned off by a partition wall 11'. In order to efficiently incorporate this partition wall 11', a gear case 1al that covers the transmission gear device 2 and a chain case that covers the output distribution device 4 are formed separately, and the chain case further includes a gear case side portion 1b' and a chain cover 1c.
The partition wall 11' is cast integrally with the gear case side part 1b'. The transfer case 1' shown in the above-mentioned publication has problems in that it has a long overall length, is heavy, has a complicated structure, and is difficult to assemble. In order to solve such problems, the present inventor invented a transfer case 1'' for a four-wheel drive vehicle as shown in FIG. In comparison, it is assumed that the gear case side part 1b' and the chain cover lcl in FIG. 1 are integrally cast, and the partition wall 11''
is abolished, and one end surface of the gear chamber 3 is configured to be entirely open to the output distribution chamber 5. One end of the counter shaft 8 of the speed change gear device 2 crosses the output distribution chamber 5 and is supported by the chain case 1b''.The other structure of the chain transmission device 10 is the same as that shown in Publication No. 1. . According to the transfer case IIT for a four-wheel drive vehicle configured in this way, the overall length can be made shorter and lighter in weight than that shown in the above-mentioned Utility Model Application Publication No. 53-121642, and the structure is also improved. This provides advantages such as easy assembly and easy assembly. However, according to the transfer case 1'' for a four-wheel drive vehicle configured in this way, since the oil can freely flow across the gear chamber 3 and the output distribution chamber 5, the output distribution chamber 5 is The oil level in the gear chamber 3 is at the same level as the gear chamber 3. Therefore, a new problem arises in that a large oil agitation resistance occurs, especially in the output distribution chamber 5 in which the chain transmission device 10 is built. The oil scattered within the output distribution chamber 5 and the oil carried upward by the traveling chain 710c are forcibly returned downward at a high speed by the chain transmission device 10, so that the oil scattered within the output distribution chamber 5 As a result, the oil level is high near the driven sprocket 10b of the chain transmission 10, and the agitation resistance of the oil against the chain transmission 10 is as follows:
It has become extremely large.

装置に対するオイルの攪拌抵抗を著しく低減できる。As described above, according to the present invention, the gear chamber housing the transmission gear device in the transfer case, the rear export force shaft, and the front export force shaft are interlocked and connected by a chain transmission device, and the output is transferred between the front and rear. The output distribution chamber that houses the chain-type output distribution device that distributes to the wheels is formed in a series so that one end surface of the gear chamber is completely open to the output distribution chamber, which corresponds to a conventional partition wall. Since the transfer case is eliminated, the transfer case can be made smaller and lighter, and the structure is simpler, making assembly easier. Furthermore, during operation, oil scraped up by the chain transmission and transmission gear is scattered in the form of droplets inside the transfer case, but inside the output distribution chamber, the oil is scattered in the upper space of the chain transmission. , Since an oil guide was installed to temporarily store oil, the oil that is scattered,
In particular, the oil, which in the conventional example re-adhered to the cheno transmission and was forcibly returned downward at a high speed, is received by the oil guide and temporarily stored. Thereafter, this oil is gradually returned to the lower part of the output distribution chamber from the lower side of the oil guide. As a result of the oil being temporarily stored in the oil guide in this way, the amount of oil that is returned to the lower part of the outlet distribution chamber at a faster speed by the Cheno transmission is smaller than before, and the output during operation is reduced. The height of the oil level in the distribution chamber can be kept low, and the oil agitation resistance to the chain transmission can be significantly reduced.

FIGS. 3 and 4 show an example of a transfer case for a four-wheel drive vehicle according to the present invention. Inside the transfer case 1, there are provided a gear chamber 3 that accommodates a transmission gear device 2, and an output distribution chamber 5 that accommodates a chenette type output distribution device 4 that distributes output to front and rear wheels. Inside the output distribution chamber 5, there is a rear export force shaft 7 arranged coaxially with the input shaft 6, and a counter shaft 8 of the transmission gear device 2 at a predetermined distance from the rear output power shaft 7. The input shaft 6 and the front export force shaft 9 arranged parallel to the rear export force axis 7 are inserted,
Further, a chain transmission device 10 is provided over both output shafts 7 and 9 to interlock and connect them. This chain transmission device 10 includes a driving sprocket 10 fixed to a rear export force shaft.
a, and a driven sprocket 10 fixed to the front export force shaft 9
b, and a chain IOc wrapped around both sprockets 10a and 10b. The output distribution chamber 5 that houses the output distribution device 4 configured in this way usually has an input shaft 6, a counter shaft 8, and an input shaft 6, as shown in FIG.
It is formed in a shape that extends closer to the front export force shaft 9 than the gear chamber 3 that houses the rear export force shaft 7, that is, in this example, extends diagonally downward to the left in FIG. 4. The transfer case 1 is formed by being divided into a gear case 1a that covers part of the gear chamber 3 and the output distribution chamber 5, and a chino case 1b that covers the remainder of the output distribution chamber 5. The end surface of the gear chamber 3 in the gear case la on the output distribution chamber 5 side is formed so as to be entirely open to the output distribution chamber 5. Inside the output distribution chamber 5, in the space above the chino transmission 10, there is an oil guide 11 for temporarily storing oil (the hunting part in FIG. 3).
is provided. In this example, the oil guide 11 is formed integrally with the inner wall of the chenoke case 1b so as to protrude into the output distribution chamber 5, and the protruding tip thereof is
Gear case 1a facing the inner wall of the Cheno case 1b
It is in contact with the inner wall IC. The upper and lower gaps between the oil guide 11 and the ceiling of the cheno case 1b are formed on the upper side with respect to the rotational direction of the chenno 10c of the chenno transmission 10, that is, at the inlet 12 of the oil guide 11, the scattered oil is removed. The receiver is large so that it can be easily stopped, and on the other hand, on the lower side, that is, at the outlet 13 of the oil guide 11, it is formed small enough to allow the stored oil to leak little by little. Since the transfer case 1 configured in this manner does not have a portion corresponding to a conventional partition wall, the overall length can be made shorter and lighter than the conventional case. Further, since the transfer case 1 is composed of the gear case 1a and the cheno case 1b, the structure is simple and the assembly work is easy. In particular, forming the oil guide 11 integrally with the cheno case 1b can reduce the number of parts and reduce the cost.
1 can be provided, and the work of assembling the transfer case 1 becomes even simpler and easier, which is advantageous. Now, driving/following sprocket 1 of Cheno transmission IO
For example, if 0a and 10c are rotated counterclockwise in FIG. 10c causes the oil to flow in a counterclockwise direction, and the oil is raked up into the output distribution chamber 5 and scattered.
As the chino 10c rotates, oil is carried above the output distribution chamber 5 and is scattered. The oil scattered in this way will not only fall naturally, but also fall onto the drive sprocket 1.
Cheno 1 on the side that hangs from 0a to driven sprocket 10b
0C forces it to return downward at a fast speed. In the present invention, since the oil guide 11 is provided, the oil that is forcibly returned is stopped from the inlet 12 of the oil guide 11 which is wide open, and is temporarily stored in this oil guide 11. Guide 1
The oil is returned to the lower part of the output distribution chamber 5 so as to leak little by little from the outlet 13 of 1. As a result, compared to the past, the amount that is forced downward at a faster speed is extremely small, and the output distribution chamber 5
can keep the oil level low. Therefore, the agitation resistance of the oil to the ceno 10c is significantly reduced. Note that the scope of the present invention is not limited to the above-described embodiments, and in the embodiments, the oil guide is formed integrally with the Cheno case, but for example, the oil guide may be formed integrally with the gear case. Alternatively, a separate oil guide may be installed. In short, it is sufficient that the oil in the output distribution chamber is temporarily stored, and the specific shape and configuration are not critical.
