Description
【０００１】[0001]
本考案は、ミッションケ−ス内の、ミッションユニットの上方に、各歯車にオ イルを導くオイルパスを備えた変速機の潤滑構造に関する。 The present invention relates to a lubricating structure for a transmission, which includes an oil path for guiding oil to each gear above a mission unit in a mission case.
【０００２】[0002]
一般に、歯車変速機においては、ミッションケ−ス内に封入した潤滑油の上方 位置にて回転可能に上記ミッションケ−スに軸支されるシャフトに、その一端か ら軸方向へ延びる給油孔とその径方向へ延びて外周及び上記給油孔に開口する複 数の流出孔を設け、上記潤滑油を上記シャフトの給油孔及び流出孔を通じて同シ ャフトに組付けた各歯車の軸受部、摺動部等へ供給するようにしている。そして 、ミッションケ−スのミッションユニットの上方内部に配設され各歯車に潤滑油 を導く略樋形状のオイルパスと、該オイルパスをシャフトの潤滑孔の一端開口部 に接続する連通路を備えており、歯車によって掻き揚げられた潤滑油をオイルパ スに集め、連通路を通じて給油孔に導き、かつ流出孔を通じてシャフト上に組付 けた各歯車の軸受部、摺動部等へ供給し、当該部を潤滑するようにしている。 Generally, in a gear transmission, a shaft that is rotatably supported by the above-mentioned mission case rotatably above the lubricating oil enclosed in the mission case is provided with an oil supply hole extending from one end thereof in the axial direction. A plurality of outflow holes that extend in the radial direction and open to the outer circumference and the oil supply hole are provided, and the bearings of each gear that slides the lubricating oil through the oil supply hole and the outflow hole of the shaft into the same shaft and slides. I am trying to supply it to the department. Further, it is provided with a substantially trough-shaped oil path arranged inside the mission unit of the mission case and guiding the lubricating oil to each gear, and a communication passage connecting the oil path to one end opening of the lubricating hole of the shaft. The lubricating oil scraped up by the gears is collected in an oil path, guided to the oil supply hole through the communication passage, and supplied to the bearings, sliding parts, etc. of each gear mounted on the shaft through the outflow hole. I try to lubricate the parts.
【０００３】 例えば実開昭６１−１１４１５６号公報に記載されるように、通常のオイルパ スのほかに、別のオイルパスを設け、該オイルパスに開口部を形成し、該開口部 を通じて潤滑油を歯車に対して供給するものは知られている。For example, as described in Japanese Utility Model Laid-Open No. 61-114156, another oil path is provided in addition to a normal oil path, an opening is formed in the oil path, and a lubricating oil is provided through the opening. Are known to supply gears to gears.
【０００４】[0004]
ところが、そのようなものは、２つのオイルパスを有するものであり、歯車に よって掻き揚げられる潤滑油が少い場合、全ての歯車に開口部を通じて上記潤滑 油を供給するようにすると、十分な潤滑を行うことができない。 However, such a device has two oil paths, and when the amount of lubricating oil scraped up by the gears is small, it is sufficient to supply all the gears with the lubricating oil through the openings. Inability to lubricate.
【０００５】 本考案は、掻き揚げられる潤滑油が少ない場合の潤滑性能を高めた変速機の潤 滑構造を提供するものである。The present invention provides a lubrication structure for a transmission with improved lubrication performance when a small amount of lubricating oil is scraped up.
【０００６】[0006]
本考案は、ミッションケ−ス内の、ミッションユニットの上方に、１対の傾斜 面を有し各歯車にオイルを導く断面略Ｖ字形状のオイルパスを備えた変速機の潤 滑構造を前提とするもので、上記オイルパスには、該オイルパスの谷底線上に位 置する第１油流出部と、傾斜面上に位置する第２油流出部とがそれぞれ形成され ている構成とする。 The present invention is premised on a lubrication structure of a transmission in a mission case, which has a pair of inclined surfaces and which has an oil path having a substantially V-shaped cross section for guiding oil to each gear, above the mission unit. Therefore, the oil path is configured to have a first oil outflow portion located on the valley bottom line of the oil path and a second oil outflow portion located on the inclined surface.
【０００７】[0007]
潤滑油量の少ない低回転時には、少い潤滑油が、第１油流出部を通じて、潤滑 の必要な歯車だけに導かれる。潤滑油量が増加する高回転時には、潤滑油量が増 加するため、その他の歯車にも、第２油流出部を通じて導かれる。 At low revolutions with a small amount of lubricating oil, a small amount of lubricating oil is introduced to the gears that require lubrication through the first oil outflow portion. At the time of high rotation where the amount of lubricating oil increases, the amount of lubricating oil increases, so that it is guided to other gears through the second oil outflow portion.
【０００８】[0008]
以下、本考案の実施例を図面に沿って詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
【０００９】 歯車変速機の潤滑構造を示す図１において、１はミッションケ−スで、その内 部にミッションユニット２が配設されている。ミッションユニット２は、ミッシ ョンケ−ス１に回転可能に軸支されたプライマリシャフト３及びセカンダリシャ フト４と、該各シャフト３，４に組付けられた変速ギヤ列とにより構成されてい る。プライマリシャフト３はクラッチ手段（図示省略）を介してエンジンのクラ ンクシャフトに連結されている。セカンダリシャフト４は、デファレンシャル装 置のリングギヤ５に連係されている。そして、各シャフト３，４に組付けられた 変速ギヤ列は互いに噛合するようになっている。In FIG. 1 showing a lubrication structure of a gear transmission, reference numeral 1 is a mission case, and a mission unit 2 is arranged inside the mission case. The mission unit 2 is composed of a primary shaft 3 and a secondary shaft 4 which are rotatably supported by the mission case 1 and a transmission gear train assembled to the shafts 3 and 4. The primary shaft 3 is connected to the crankshaft of the engine via clutch means (not shown). The secondary shaft 4 is linked to a ring gear 5 of a differential device. The transmission gear trains assembled on the shafts 3 and 4 are in mesh with each other.
【００１０】 また、デファレンシャル装置のリングギヤ５の下側略半分が潤滑油６中に浸漬 されている。これによって、潤滑油６の一部が、リングギヤ５によって上方に掻 き揚げられるようになっている。Further, the lower half of the ring gear 5 of the differential device is immersed in the lubricating oil 6. As a result, part of the lubricating oil 6 is scraped upward by the ring gear 5.
【００１１】 上記ミッションケ−ス１内で、かつミッションユニット２の上方には、各変速 ギヤに潤滑油を導くオイルパス１１が上記両シャフト３，４の軸線に沿って配設 されている。Inside the mission case 1 and above the mission unit 2, an oil path 11 for guiding lubricating oil to each transmission gear is arranged along the axes of the shafts 3 and 4.
【００１２】 オイルパス１１は、図２〜図６に示すように、断面略Ｖ字形状を形成する１対 の傾斜面部１１ａ，１１ｂと、該傾斜面部１１ａ，１１ｂの両側縁より上方に延 びる縦壁部１１ｃ，１１ｄとを有する。また、オイルパス１１の上下方向の高さ の最も低い傾斜面部１１ａ，１１ｂの交叉部上、いわゆる谷底線１１ｅ上に第１ 油流出部としての第１開口部１３ａ，１３ｂ，１３ｃ，１３ｄ，１３ｅ，１３ｆ ，１３ｇが、該第１開口部１３ａ〜１３ｇより若干高さが高い位置の傾斜面部１ １ａ，１１ｂに第２油流出部としての第２開口部１４ａ，１４ｂ，１４ｃがそれ ぞれ若干下方に突出して形成されている。これによって、潤滑油の少い低回転時 には第１開口部１３ａ〜１３ｇのみを通じて、潤滑油が多い高回転時には、第１ 及び第２開口部１３ａ〜１３ｇ，１４ａ〜１４ｃを通じて潤滑油が供給されるこ とになる。As shown in FIGS. 2 to 6, the oil path 11 extends upward from a pair of inclined surface portions 11 a and 11 b forming a substantially V-shaped cross section and both side edges of the inclined surface portions 11 a and 11 b. It has vertical wall portions 11c and 11d. The first opening 13a, 13b, 13c, 13d, 13e as the first oil outflow portion is formed on the intersection of the inclined surface portions 11a, 11b having the lowest vertical height of the oil path 11, that is, on the so-called valley bottom line 11e. , 13f and 13g are slightly higher than the first openings 13a to 13g, and the second openings 14a, 14b and 14c as the second oil outflow parts are slightly provided on the inclined surface parts 11a and 11b. It is formed so as to project downward. As a result, the lubricating oil is supplied only through the first openings 13a to 13g when the rotation speed is low with a small amount of lubricating oil, and through the first and second openings 13a to 13g and 14a to 14c when the rotation speed is high with a large amount of lubricating oil. Will be done.
【００１３】 ここで、第１開口部１３〜１３ｇは、それぞれ、リバ−スシンクロ装置２１、 ５速用変速ホ−ク（図示せず）、５速用シンクロ装置２３、軸受部２４、４速用 シンクロ装置２５、３速用変速ホ−ク２６（図５参照））及び３速用シンクロ装 置２７に対応して設けられている。また、第２開口部１４ａ，１４ｂ，１４ｃは 、リバ−ス用変速ギヤ３１、５速用変速ギヤ３２及び４速用変速ギヤ３３にそれ ぞれ対応して設けられている。Here, the first openings 13 to 13g are respectively provided with a reverse synchro device 21, a fifth speed gear shift horn (not shown), a fifth speed synchro device 23, a bearing portion 24, and a fourth speed gear. The synchro device 25 is provided corresponding to the 3rd speed shift hood 26 (see FIG. 5)) and the 3rd speed synchro device 27. The second openings 14a, 14b, 14c are provided corresponding to the reverse gear 31, the fifth speed gear 32, and the fourth speed gear 33, respectively.
【００１４】 オイルパス１１は、プライマリシャフト３の端部付近において、連通部材１５ を介して、プライマリシャフト３の中心軸線に沿って延びる給油孔３ａに潤滑油 を供給するようになっている。１６はミッションケ−ス１の端部に設けられたカ バ−部材である。The oil path 11 supplies the lubricating oil to the oil supply hole 3 a extending along the central axis of the primary shaft 3 via the communication member 15 in the vicinity of the end of the primary shaft 3. Reference numeral 16 is a cover member provided at the end of the mission case 1.
【００１５】 また、オイルパス１１は、プライマリシャフト３の端部になるほど高さが低く なるように傾斜して配置され、潤滑油が流れ易くなるようになっている。Further, the oil path 11 is arranged so as to be inclined so that the height thereof becomes lower toward the end portion of the primary shaft 3, so that the lubricating oil can easily flow.
【００１６】 また、オイルパス１１の上側には、一方の縦壁部１１ｃの上縁から他方の縦壁 部１１ｄの上方を越えて延びるガイド部材４１が一体的に形成されている。ガイ ド部材４１は、リングギヤ５が潤滑油を掻き揚げる部位に対してのみ設けられ、 リングギヤ５によって掻き揚げられた潤滑油を、ガイド部材４１の下面４１ａに 沿わせて案内してオイルパス１１に導くようになっている。A guide member 41 is integrally formed on the upper side of the oil path 11 and extends from the upper edge of the one vertical wall portion 11c to over the other vertical wall portion 11d. The guide member 41 is provided only for the portion where the ring gear 5 scrapes up the lubricating oil, and guides the lubricating oil scraped up by the ring gear 5 along the lower surface 41a of the guide member 41 to the oil path 11. It is designed to guide you.
【００１７】 上記のように構成すれば、リングギヤ５によって掻き揚げられた潤滑油は、ガ イド部材４１の下面４１ａに付着し、該下面４１ａが傾斜していることからその 下面４１ａに沿ってオイルパス１１の方へ案内され、オイルパス１１内に導かれ る。ガイド部材４１は、リングギヤ５が潤滑油を掻き揚げる部位に設けているの で、リングギヤ５によって掻き揚げられた潤滑油は無駄なく、確実にオイルパス １１に案内される。According to the above structure, the lubricating oil scraped up by the ring gear 5 adheres to the lower surface 41a of the guide member 41, and the lower surface 41a is inclined. You will be guided towards Pass 11 and guided into Oil Pass 11. Since the guide member 41 is provided at the portion where the ring gear 5 scrapes up the lubricating oil, the lubricating oil scraped up by the ring gear 5 is reliably guided to the oil path 11 without waste.
【００１８】 オイルパス１１内に案内された潤滑油は、低回転時には、潤滑油の量が少いこ とから、第１開口部１３ａ〜１３ｇを通じてのみ潤滑油が供給され、潤滑の必要 なシンクロ装置等にのみ潤滑油を供給することで、潤滑油を有効に供給するよう にしている。尚、潤滑油量の最小供給量は約４０cc/min（推定）程度である。Since the lubricating oil guided in the oil path 11 has a small amount of lubricating oil at low rotation speed, the lubricating oil is supplied only through the first openings 13a to 13g, and the synchronizing device requiring lubrication is required. By supplying the lubricating oil only to the etc., the lubricating oil is effectively supplied. The minimum supply amount of lubricating oil is about 40 cc / min (estimated).
【００１９】 一方、高回転時には、潤滑油の量が多くなるので、第１開口部１３ａ〜１３ｇ のみならず、第２開口部１４ａ〜１４ｃを通じても潤滑油が供給されることとな り、その他の潤滑が必要なギヤ等にも潤滑油が供給される。そして、潤滑油は、 連通部材１５を介してプライマリシャフト３の給油孔３ａに供給される。尚、潤 滑油量の最大供給量は約４００cc/min（推定）程度である。On the other hand, at high rotation speed, the amount of lubricating oil increases, so that the lubricating oil is supplied not only through the first openings 13a to 13g but also through the second openings 14a to 14c. Lubricating oil is also supplied to gears that require lubrication. Then, the lubricating oil is supplied to the oil supply hole 3 a of the primary shaft 3 via the communication member 15. The maximum supply of lubricating oil is about 400cc / min (estimated).
【００２０】 これによって、低回転、高回転の運転状態に応じて潤滑油の供給が行われ、潤 滑性能が向上する。As a result, the lubricating oil is supplied according to the operating conditions of low rotation and high rotation, and the lubrication performance is improved.
【００２１】 上記実施例では、第２油流出部を第１開口部１３ａ〜１３ｇと同様に開口部と しているが、第２油流出部を縦壁部の上端縁に開放する切欠きとすることもでき る。In the above embodiment, the second oil outflow portion is the same as the first opening portions 13a to 13g, but the second oil outflow portion has a notch for opening to the upper edge of the vertical wall portion. You can also do it.
【００２２】[0022]
本考案は、上記のように構成したから、潤滑油量の少ない低回転時には、少い 潤滑油が、第１油流出部を通じて、潤滑の必要な歯車だけに導かれる一方、潤滑 油量が増加する高回転時には、潤滑油量が増加するため、その他の歯車にも、第 ２油流出部を通じて導かれることとなり、潤滑油量にかかわりなく、良好な潤滑 が図れる。 Since the present invention is configured as described above, a small amount of lubricating oil is guided to only the gears requiring lubrication through the first oil outflow portion at the time of low rotation with a small amount of lubricating oil, while the amount of lubricating oil increases. At high rotation speed, the amount of lubricating oil increases, so that it is guided to the other gears through the second oil outflow portion, and good lubrication can be achieved regardless of the amount of lubricating oil.
