Description

本発明は、車両用デファレンシャル装置に関し、詳細にはデフケースを支持する軸受回りの潤滑に関する。   The present invention relates to a vehicle differential device, and more particularly to lubrication around a bearing that supports a differential case.

この種のデファレンシャル装置では、ハウジング内に充填された潤滑油をデフケースの外壁に固定されたデフリングギヤにより掻き揚げることによって軸受等の各摺動部に供給する場合がある。例えば、特許文献１には、ベアリング収納凹部に、デフリングギヤの回転によって飛散した潤滑油を受け止める油受けリブと、該油受けリブで受け止めた潤滑油を軸受に導くガイドリブとを形成したものが提案されている。
特開平１１−４８８０６号公報 In this type of differential device, there is a case where the lubricating oil filled in the housing is supplied to each sliding portion such as a bearing by being lifted up by a diff ring gear fixed to the outer wall of the differential case. For example, Patent Document 1 proposes that a bearing receiving recess is formed with an oil receiving rib for receiving the lubricating oil scattered by the rotation of the diff ring gear, and a guide rib for guiding the lubricating oil received by the oil receiving rib to the bearing. Has been.
JP-A-11-48806

ところで、上記従来装置のように、デフリングギヤにより飛散した潤滑油を受け止めて軸受に導く構造を採用した場合には、撹拌抵抗によるデフリングギヤのメカニカルロスが大きくなるという問題がある。   By the way, when adopting a structure in which the lubricating oil scattered by the diff ring gear is received and guided to the bearing as in the conventional device, there is a problem that the mechanical loss of the diff ring gear due to agitation resistance increases.

そこで、潤滑油による撹拌抵抗の低減を図るために、デフケース内にセパレートプレートを配設することが考えられる。しかしながら、セパレートプレートを単に配設した場合には、上記油受けリブへの潤滑油の飛散量が減少し易く、場合によっては潤滑性が低下するおそれがある。   Therefore, in order to reduce the stirring resistance by the lubricating oil, it is conceivable to arrange a separate plate in the differential case. However, when the separate plate is simply disposed, the amount of the lubricating oil scattered on the oil receiving rib is likely to decrease, and in some cases, the lubricity may be lowered.

本発明は、上記従来の実情に鑑みてなされたもので、潤滑油による撹拌抵抗の低減を図ることができ、かつ軸受への潤滑油量を確保できる車両用デファレンシャル装置を提供することを目的としている。   The present invention has been made in view of the above-described conventional situation, and an object of the present invention is to provide a vehicle differential apparatus that can reduce agitation resistance due to lubricating oil and can secure the amount of lubricating oil to the bearing. Yes.

本発明は、差動歯車機構を備えたデフケースの軸方向両端部が軸受を介してハウジングにより支持され、上記デフケースの外壁にデフリングギヤが軸方向中心部より一側に偏位させて設けられた車両用デファレンシャル装置において、上記ハウジングの上記デフケースの軸方向他側に臨む部分に該デフケースの回転方向と対向するよう延びるリブを形成し、上記ハウジング内をセパレートプレートにより上記デフリングギヤが配置された一側室と、上記リブが形成された他側室とに区分けし、上記セパレートプレートとリブとで上記デフリングギヤにより掻き揚げられた潤滑油の一部を溜める油溜まり部を形成し、該油溜まり部の潤滑油を少なくとも上記軸受に供給する連通路を設けたことを特徴としている。   In the present invention, both end portions in the axial direction of a differential case provided with a differential gear mechanism are supported by a housing via a bearing, and a differential ring gear is provided on the outer wall of the differential case so as to be deviated to one side from the central portion in the axial direction. In the vehicle differential device, a rib extending so as to face the rotation direction of the differential case is formed in a portion of the housing facing the other side in the axial direction of the differential case, and the differential ring gear is disposed in the housing by a separate plate. It is divided into a side chamber and the other side chamber in which the rib is formed, and an oil reservoir portion is formed by the separate plate and the rib to store a part of the lubricating oil swept up by the diff ring gear. A communication path for supplying at least lubricating oil to the bearing is provided.

本発明に係るデファレンシャル装置によれば、ハウジング内をセパレートプレートによりデフリングギヤが配置された一側室と他側室とに区分けしたので、デフリングギヤにより掻き揚げられた一側室の潤滑油の一部が他側室に流入することとなり、それだけ一側室の潤滑油量を減らすことができ、撹拌抵抗を低減できる。   According to the differential device of the present invention, the inside of the housing is divided into the one side chamber in which the diffring gear is arranged by the separate plate and the other side chamber, so that a part of the lubricating oil in the one side chamber swept up by the diffring gear is another As a result, the amount of lubricating oil in one side chamber can be reduced, and the stirring resistance can be reduced.

本発明では、ハウジングに形成されたリブとセパレートプレートとで潤滑油の一部を溜める油溜まり部を形成し、該油溜まり部の潤滑油を軸受に供給するようにしたので、油溜まり部に潤滑油を溜めておくことができ、従来の飛散した潤滑油を受け止めてそのまま軸受に供給する場合に比べて軸受に供給する潤滑油の必要量を確保することができる。   In the present invention, the oil reservoir portion for storing a part of the lubricating oil is formed by the rib formed on the housing and the separate plate, and the lubricating oil in the oil reservoir portion is supplied to the bearing. Lubricating oil can be stored, and the required amount of lubricating oil to be supplied to the bearing can be ensured as compared with the case where the conventional scattered lubricating oil is received and supplied to the bearing as it is.

またハウジングの剛性を高めるためのリブと、撹拌抵抗を低減するためのセパレートプレートとで油溜まり部を形成したので、特別な部品を追加することなく潤滑性の改善を図ることができる。   Further, since the oil reservoir is formed by the rib for increasing the rigidity of the housing and the separate plate for reducing the stirring resistance, the lubricity can be improved without adding any special parts.

The separate plate 35 is formed with a hole 35d for returning the lubricating oil in the right chamber B.

上記セパレートプレート３５の第１セパレート部３５ａには、上記最下端に位置するリブ２８ｅより高所に位置するよう上方に延びる延長部３５ｃが形成されている。また上記リブ２８ｅの先端面は上記延長部３５ｃの傾斜面に当接又は近接している。さらに上記リブ２８ｅは油面ａに対して斜め上向きに傾斜している。   The first separation portion 35a of the separation plate 35 is formed with an extension portion 35c extending upward so as to be positioned higher than the rib 28e located at the lowermost end. Further, the tip surface of the rib 28e is in contact with or close to the inclined surface of the extension portion 35c. Further, the rib 28e is inclined obliquely upward with respect to the oil surface a.

そして上記セパレートプレート３５の延長部３５ｃとリブ２７ｅ及びハウジング本体２７ａの外壁２７ａ′とで囲まれた部分が油溜まり部３７となっている。この油溜まり部３７はデフリングギヤ７ａにより掻き揚げられた潤滑油の一部が溜まるよう上向きに開口している。   A portion surrounded by the extension 35 c of the separate plate 35, the rib 27 e and the outer wall 27 a ′ of the housing body 27 a is an oil reservoir 37. The oil reservoir 37 is opened upward so that a part of the lubricating oil scraped up by the diff ring gear 7a is accumulated.

また上記油溜まり部３７の底部を形成するボス部２７ｃには、油溜まり部３７ｅと軸受３２の外側とを連通する連通路３８が形成されている。この連通路３８はボス部２７ｃと軸受３２の外面との間に形成されており、該軸受３２と上記オイルシール８ｃとの間に潤滑油を導くようになっている。この導かれた潤滑油は上記軸受３２の転動面，上記オイルシール８ｃの摺動面を潤滑し、さらに上記出力軸８のスプライン噛合面を潤滑する。   The boss portion 27 c that forms the bottom of the oil reservoir portion 37 is formed with a communication path 38 that communicates the oil reservoir portion 37 e with the outside of the bearing 32. The communication path 38 is formed between the boss portion 27c and the outer surface of the bearing 32, and guides lubricating oil between the bearing 32 and the oil seal 8c. The guided lubricating oil lubricates the rolling surface of the bearing 32 and the sliding surface of the oil seal 8c, and further lubricates the spline meshing surface of the output shaft 8.

上記デフハウジング部２７内には潤滑油が充填されており、該潤滑油の油面ａは車両停止状態でデフケース２６の軸心付近に位置している。   The differential housing portion 27 is filled with lubricating oil, and the oil level a of the lubricating oil is located near the axis of the differential case 26 when the vehicle is stopped.

車両が走行状態となると、デフリングギヤ７ａとともにデフケース２６が回転し、該デフリングギヤ７ａの回転に伴って左側室Ａの潤滑油が掻き揚げられ、セパレートプレート３５の上方から右側室Ｂに流入する。この右側室Ｂに流入した潤滑油の一部は油溜まり部３７に溜まり、ここから連通路３８を通って軸受３２，オイルシール８ｃに供給される。   When the vehicle enters a traveling state, the differential case 26 rotates together with the differential ring gear 7a, and the lubricating oil in the left chamber A is swept up along with the rotation of the differential ring gear 7a, and flows into the right chamber B from above the separate plate 35. A part of the lubricating oil flowing into the right chamber B is accumulated in the oil reservoir 37, and is supplied to the bearing 32 and the oil seal 8c through the communication path 38 from here.

本実施形態によれば、デフハウジング部２７内をセパレートプレート３５によりデフリングギヤ７ａが配置された左側室Ａと、リブ２７ｅが形成された右側室Ｂとに区分けしたので、デフリングギヤ７ａにより掻き揚げられた潤滑油の一部が右側室Ｂに流入することとなる。その結果、左側室Ａの潤滑油量が減る分だけ、デフリングギヤ７ａが受ける撹拌抵抗を低減できる。   According to the present embodiment, the inside of the differential housing portion 27 is divided into the left chamber A where the differential ring gear 7a is disposed by the separate plate 35 and the right chamber B where the rib 27e is formed. A part of the obtained lubricating oil flows into the right chamber B. As a result, the agitation resistance received by the diff ring gear 7a can be reduced by the amount that the amount of lubricating oil in the left chamber A decreases.

本実施形態では、デフハウジング部２７のリブ２７ｅ及び外壁２７ａ′と、セパレートプレート３５とで潤滑油を溜める油溜まり部３７を形成し、該油溜まり部３７の潤滑油を連通路３８を介して軸受３２に供給するようにしたので、デフリングギヤ７ａにより掻き揚げられた潤滑油は油溜まり部３７に一旦溜まることとなり、従来の飛散した潤滑油をそのまま軸受に供給する場合に比べて軸受３２に供給するための潤滑油の必要量を確保することができる。   In the present embodiment, the rib 27e and the outer wall 27a 'of the differential housing portion 27 and the separate plate 35 form an oil reservoir portion 37 for storing lubricating oil, and the lubricating oil in the oil reservoir portion 37 is passed through the communication path 38. Since the lubricating oil pumped up by the diff ring gear 7a is temporarily stored in the oil reservoir 37, the lubricating oil scattered to the bearing 32 is compared with the conventional case where the scattered lubricating oil is supplied to the bearing as it is. The required amount of lubricating oil for supply can be ensured.

また上記デフハウジング部２７の剛性を高めるためのリブ２７ｅと、撹拌抵抗を低減するためのセパレートプレート３５とで油溜まり部３７を形成したので、特別な部品を追加することなく潤滑性の改善を図ることができる。   Further, since the oil reservoir portion 37 is formed by the rib 27e for increasing the rigidity of the differential housing portion 27 and the separation plate 35 for reducing the stirring resistance, the lubricity can be improved without adding special parts. Can be planned.

また上記実施例では、リブ２７ｅがデフケース２６の回転方向と直交する方向、換言すればハウジング本体２７ａの型割方向に延びているので、鋳造作業を複雑化することなく上記油溜まり部３７を形成することができる。   In the above embodiment, the rib 27e extends in the direction orthogonal to the rotation direction of the differential case 26, in other words, in the mold splitting direction of the housing body 27a, so that the oil reservoir 37 is formed without complicating the casting operation. can do.
