この考案は、自動車等に使用されている歯車式変速機の
潤滑装置に関するものである。[Detailed Description of the Invention] This invention relates to a lubricating device for a gear type transmission used in automobiles and the like.
この種の潤滑装置としては、変速機箱の底部に形成した
油溜室内の潤滑油を歯車群によって各部に掻き上げ給油
させるのが一般的である。This type of lubricating device generally uses a group of gears to scoop up lubricating oil in an oil reservoir formed at the bottom of a transmission box and supply the lubricating oil to each part.
又、変速機内部を充分に潤滑させるためには、最下部に
設けたすべての歯車によって潤滑油を掻き上げさせる必
要がある。In addition, in order to sufficiently lubricate the inside of the transmission, it is necessary to scrape up the lubricating oil with all the gears provided at the lowest position.
ところが、一般には、最下部にカウンタシャフトを設け
、このシャフトに大小様々の歯車を装着しているので、
潤滑油面を最も小径の歯車に合わせる必要がある。However, in general, a counter shaft is installed at the bottom, and gears of various sizes are attached to this shaft.
It is necessary to match the lubricating oil level to the smallest diameter gear.
すると、カウンタシャフトに装着された大径の歯車が必
要以上に潤滑油を攪拌するため、油温が異常に上昇し、
又は、シンクロ操作力が重くなるなどの不都合が生じる
ことがある。Then, the large diameter gear attached to the countershaft stirs the lubricating oil more than necessary, causing the oil temperature to rise abnormally.
Alternatively, inconveniences such as increased synchronization operation force may occur.
この考案は、上記に鑑みてなされたものであって、潤滑
油の攪拌抵抗が増加する中高速運転時は変速材箱底部に
形成された主室内の潤滑油を歯車群の上方に設けた副室
内に自動的に貯溜させて犬歯主群による攪拌抵抗を低減
させつつ前記副室から小歯車群に給油して潤滑性を確保
し、又、犬歯主群による攪拌抵抗が減少する停止時及び
低速運転時には副室内の潤滑油を自動的に主室内に戻し
てその油面を確保し、小歯車群による掻き上げ油量をも
確保して所期の潤滑を行わせることにより、潤滑性を損
うことなく油温の上昇とシンクロ操作力の増加とを効率
よく抑制することを目的とするものである。This idea was made in view of the above, and during medium and high speed operation where the agitation resistance of the lubricating oil increases, the lubricating oil in the main chamber formed at the bottom of the transmission box is transferred to a secondary tank located above the gear group. Lubricating oil is automatically stored in the chamber to reduce the stirring resistance caused by the main canine group, and the small gear group is supplied from the auxiliary chamber to ensure lubricity. During operation, the lubricating oil in the auxiliary chamber is automatically returned to the main chamber to secure the oil level, and the small gear group also secures the amount of oil scraped up to perform the desired lubrication, thereby preventing loss of lubricity. The purpose is to efficiently suppress an increase in oil temperature and an increase in synchro operation force without causing any problems.
以下、添付図面に示された一実施例に基づいてこの考案

とを軸架している。In the figure, 1 is a transmission box in which a main drive pinion 2 and a main shaft 3 are mounted on the same axis, and meshes with gears 4a, 4b, . . . , 4m attached to the pinion 2 and the main shaft 3. Counter shaft 6 equipped with counter gears 5a, 5b...5n
It is supported by a shaft.
前記変速機箱１の底部には前記各カウンタ歯車５ａ 、
５ｂ・・・５ｎによって掻き上げ給油される潤滑油を
貯溜する主室７を形成している。At the bottom of the transmission box 1, each of the counter gears 5a,
A main chamber 7 is formed to store lubricating oil that is scooped up and supplied by the pumps 5b...5n.
８は前記歯車群の上方に形成された副宿で、掻き上げ油
量の多い歯車群、即ち、大径のカウンタ歯車５ａ、５ｂ
及び、この歯車に噛み合うメインドライブピニオン２と
歯車４ａとで掻き上げられる潤滑油の飛行方向に向って
開口する集油口９を設けている。Reference numeral 8 denotes a sub-housing formed above the gear group, which is a gear group that scrapes up a large amount of oil, that is, large-diameter counter gears 5a and 5b.
An oil collection port 9 is provided which opens in the direction of flight of the lubricating oil scooped up by the main drive pinion 2 and the gear 4a that mesh with this gear.
１０は集油口９に設けた集油管である。10 is an oil collecting pipe provided at the oil collecting port 9.
又、前記副室８の側壁には、掻き上げ油量の少ない歯車
群の上方で開口する給油口１１を設けると共に、その底
壁には排油口１２を設けている。Further, a side wall of the auxiliary chamber 8 is provided with an oil supply port 11 that opens above the gear group where the amount of oil being scraped up is small, and an oil drain port 12 is provided on the bottom wall thereof.
１３は前記集油口９に副室８の内側からスプリング１４
で弾圧保持された入口バルブ、１５は排油口１２に設け
た出口バルブであって、両バルブ１３．１５の弁軸１６

排油口を開きかつ、スプリング１４に抗して入口バルブ
１３が集油口９を開口させると出口バルブ１５が排油口
１２を閉じるようにしである。13 is a spring 14 that connects the oil collection port 9 from the inside of the auxiliary chamber 8.
15 is an outlet valve provided at the oil drain port 12, and the valve stems 16 of both valves 13 and 15 are
, 17 through the link arm 18, when the inlet valve 13 is closed, the outlet valve 15 opens the oil drain port, and the inlet valve 13 opens the oil collection port 9 against the spring 14. When the oil outlet valve 15 is turned on, the outlet valve 15 closes the oil drain port 12.
以上の構成において、カウンタシャフト６が回転される
と、各カウンタ歯車５ａ 、 ５ｂ・・・５ｎによって
主室Ｔ内の潤滑油が掻き上げられる。In the above configuration, when the counter shaft 6 is rotated, the lubricating oil in the main chamber T is scraped up by each counter gear 5a, 5b, . . . , 5n.
ここに、カウンタシャフト６が高速で回転すると、大径
のカウンタ歯車群５ａ 、５ｂによる掻き上げ油量が増
加し、これらの歯車群に噛み合うピニオン２及び歯車４
ａから集油管１０内に飛行する潤滑油圧が上昇する。Here, when the counter shaft 6 rotates at high speed, the amount of oil scraped up by the large-diameter counter gear groups 5a and 5b increases, and the pinion 2 and gear 4 that mesh with these gear groups increase.
The lubricating oil pressure flowing into the oil collecting pipe 10 increases from a.
このようにして集油口、９から流入しようとする潤滑油
圧がスプリング１４のセット圧より大きくなると、スプ
リング１４に抗して入口バルブ１３が図中右側に移動し
て集油口９を開く。When the lubricating oil pressure that is about to flow in from the oil collection port 9 becomes greater than the set pressure of the spring 14, the inlet valve 13 moves to the right in the figure against the spring 14 to open the oil collection port 9.
又、この集油口９の開口と同時に排油口１２が出口バル
ブ１５で閉じられる。Further, at the same time as the oil collection port 9 is opened, the oil drain port 12 is closed by the outlet valve 15.
その結果、掻き上げ油量の多い歯車群で掻き上げられた
潤滑油の一部が集油口から副室８内に流入して貯溜され
る。As a result, a portion of the lubricating oil scraped up by the gear group with a large amount of scraped up oil flows into the auxiliary chamber 8 from the oil collection port and is stored therein.
副室８内の潤滑油量が増加するにともなって主室７内の
潤滑油量が減少し、各カウンタ歯車５ａ、５ｂ・・・５
ｎによる攪拌抵抗が減少する。As the amount of lubricating oil in the sub chamber 8 increases, the amount of lubricating oil in the main chamber 7 decreases, and each counter gear 5a, 5b...5
The stirring resistance due to n is reduced.
又、主室７内の潤滑油量が減少すると、小径のカウンタ
歯車の掻き上げ油量が激減するのであるが、副室８内の
潤滑油量が所定値以上に達すると給油口１１から掻き上
げ油量の少ない歯車群に向って潤滑油が流下供給される
ため、潤滑性は確保される。Furthermore, when the amount of lubricating oil in the main chamber 7 decreases, the amount of oil scraped up by the small-diameter counter gear decreases dramatically, but when the amount of lubricating oil in the subchamber 8 reaches a predetermined value or more, it is scraped up from the oil filler port 11. Lubricating oil is supplied in a downward direction toward the gear group with the least amount of oil, so lubricity is ensured.

が集油口９を閉じて副室８内に潤滑油が流入するのを阻
止する。As a result, the pressure inside the oil collecting pipe 10 becomes lower than the set pressure of the spring 14, so that the inlet valve 13 is opened as shown in FIG.
closes the oil collection port 9 and prevents lubricating oil from flowing into the auxiliary chamber 8.
前記集油口９が閉じられると同時に出口バルブ１５が排
油口１２を開くため、副室８内の潤滑油は主室７内に流
下する。Since the outlet valve 15 opens the oil drain port 12 at the same time as the oil collection port 9 is closed, the lubricating oil in the auxiliary chamber 8 flows down into the main chamber 7.
従って、歯車群による攪拌抵抗の小さい時は主室７の潤
滑油面力相動的に上昇（潤滑油量が増加）するために、
小歯車群による掻き上げ油量が確保される。Therefore, when the stirring resistance due to the gear group is small, the surface force of the lubricating oil in the main chamber 7 increases phase-wise (the amount of lubricating oil increases).
The amount of oil scraped up by the small gear group is ensured.
以上説明したように、この考案に係る潤滑装置によれば

シンクロ操作性を向上できる。As explained above, according to the lubricating device according to this invention, when the agitation resistance of the lubricating oil due to the gear group increases, the lubricating oil in the main chamber is stored in the subchamber to reduce the agitating resistance and to scrape up the oil. Lubricating oil is supplied from the auxiliary chamber to gear groups with a small quantity, and when the stirring resistance is small, the lubricating oil in the auxiliary chamber is returned to the main chamber to raise the oil level, improving the lubricity inside the transmission. It is possible to suppress the rise in oil temperature without causing any damage, and it is also possible to improve synchro operability.
