ランスファ装置の潤滑装置に係る。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a /1ilI slide device for a chain-driven transfer device in a vehicle such as an automobile. More specifically, the present invention relates to a lubricating device for a chain-driven transfer device that prevents excessive temperature rise of lubricating oil.

ヤがチェーンで連結されるチェーン駆動式トランスファ
装置が用いられることがある。In vehicles such as automobiles, a chain drive type transfer device in which a drive gear and a driven gear are connected by a chain is sometimes used as a transfer device for switching from two-wheel drive to four-wheel drive.
そして、この種のチェーン駆動式トランスファ装置は、

ようになっている。And this kind of chain-driven transfer device is
Generally, a lubricating oil chamber is formed by being surrounded by a case member, and the lubricating oil contained in the lubricating oil chamber is agitated by a rotating part such as a chain or gear, so that predetermined lubricating parts are lubricated.
しかし、上述したこの種のチェーン駆動式トランスファ
装置の潤滑装置においては、潤滑油の温度が過度に高温
となることがあり、そのため潤滑油の劣化や各種シール
部材の劣化をもたらすという不都合がある。However, in the above-mentioned lubricating device for a chain-driven transfer device of this type, the temperature of the lubricating oil may become excessively high, which is disadvantageous in that it causes deterioration of the lubricating oil and deterioration of various seal members.
潤滑油の温度が上昇する原因としては、チェーンと駆動
ギヤまたば被動ギヤとの噛合いによる発熱もあるが、主
として／Ｉｌ滑油の攪拌抵抗に伴う発熱によるところが
大きい。The temperature of the lubricating oil rises due to heat generation due to the meshing of the chain with the driving gear or the driven gear, but it is mainly due to the heat generated due to the stirring resistance of the lubricating oil.
そのため、潤滑油室に多量の潤滑油が入れられるときに
は、必然的に潤滑油の攪拌抵抗が大きくなり、過度に高
温となることがある。Therefore, when a large amount of lubricating oil is put into the lubricating oil chamber, the stirring resistance of the lubricating oil inevitably increases, and the temperature may become excessively high.
尤も、このことから潤滑油室の潤滑油量を少なくするこ
とにより、潤滑油の攪拌抵抗は小さくなり、油温上昇を
押さえることができるが、潤滑油量が少ないときには、
潤滑油の使用頻度が高くなり早期に劣化が生じるため、
一般に、潤滑油室内には所定量のｓｆｋ浦を入れること
が望ましいものとされている。Of course, by reducing the amount of lubricating oil in the lubricating oil chamber, the agitation resistance of the lubricating oil can be reduced and the rise in oil temperature can be suppressed, but when the amount of lubricating oil is small,
As lubricating oil is used more frequently, it deteriorates more quickly.
Generally, it is considered desirable to put a predetermined amount of SFK into the lubricating oil chamber.
而して、本発明の目的は、潤滑油室内には所定量の潤滑
油を入れるが、攪拌される潤滑油量を少なくすることに
より、潤滑油の過度の温度上昇を防止することにある。SUMMARY OF THE INVENTION An object of the present invention is to prevent excessive temperature rise of the lubricating oil by putting a predetermined amount of lubricating oil into the lubricating oil chamber and reducing the amount of lubricating oil that is stirred.

る。[Structure of the Invention] In order to achieve this object, in the lubricating device for a chain-driven transfer device of the present invention, in the lubricating device for a chain-driven transfer device of this kind described in -, #lt oil is stirred for lubrication. In addition to the main oil reservoir formed at the bottom of the lubricating oil chamber, an oil receiver is provided in the lubricating oil chamber to form a sub oil reservoir at a position where the lubricating oil is not stirred. A lubricating oil outlet is provided.
これにより、潤滑油が攪拌潤滑されるとき、潤滑油の一
部はオイル受は部に受けられて、副オイル溜りに溜めら
れる。その結果、主オイル溜りの潤滑油量は少なくなり
、潤滑油の攪拌抵抗が小さくなる。As a result, when the lubricating oil is stirred for lubrication, a portion of the lubricating oil is received by the oil receiver and stored in the sub-oil reservoir. As a result, the amount of lubricating oil in the main oil reservoir is reduced, and the resistance to agitation of the lubricating oil is reduced.
また、副オイル溜りに溜められた潤滑油は、オイル受は
部の流出口から流出し、潤滑油の循環作用が行われる。Furthermore, the lubricating oil stored in the auxiliary oil reservoir flows out from the outlet of the oil receiver, and the lubricating oil is circulated.
本発明は、」−述したように、副オイル溜りに潤滑油を
溜めることにより、攪拌される潤滑油量が少なくなり、
攪拌抵抗が小さくなることから、潤滑油が過度に温度上
昇することがなくなる。According to the present invention, as described above, by storing lubricating oil in the auxiliary oil reservoir, the amount of lubricating oil to be stirred is reduced.
Since the stirring resistance is reduced, the temperature of the lubricating oil will not rise excessively.
また、副オイル溜りに溜められる潤滑油も順次循環する
ため、潤滑油の使用頻度が高くなるようなことがない。Furthermore, since the lubricating oil stored in the sub-oil reservoir is also circulated in sequence, the lubricating oil does not have to be used frequently.
このようなことから、／ｒＪＪ滑油の早期劣化を防止す
ることができる。For this reason, early deterioration of /rJJ lubricating oil can be prevented.
