【従来の技術及びその課題】[Prior art and its problems]

従来、自動車用手動変速機の潤滑構造は図4に概略図で示すような構造となっ ており、トランスミッションケース1に溜められたオイルOは、その上部に配設 されたデフリングギア3の回転によりかき揚げられ、デフリングギア3の周縁上 部に配設されたオイル取入口4内に集められ、集められたオイルをオイル取入口 4に接続された導管5を通して各潤滑部に供給する構造となっており、このよう な従来構造においては、デフリングギア3でかき揚げられたオイルの一部が、ト ランスミッションケース1の壁面に沿ってオイル取入口4へ集められるものであ り、デフリングギア3に例えばノンスリップ装置等を追加した場合には、トラン スミッションケースの壁面とデフリングギア3との隙間が大となり、デフリング ギア3によりかき揚げられたオイルの大部分がトランスミッションケース側へ逃 げてオイル取入口4まで届かず、そのため潤滑部に供給されるオイルの量が減少 して、潤滑が不充分になってしまうという問題点があった。 Conventionally, the lubrication structure of a manual transmission for an automobile has a structure as shown in the schematic view of FIG. 4, and the oil O accumulated in the transmission case 1 is rotated by the rotation of the differential ring gear 3 arranged above the transmission case 1. The structure is such that the oil is fried and collected in an oil intake port 4 arranged on the upper edge of the differential ring gear 3, and the collected oil is supplied to each lubrication unit through a conduit 5 connected to the oil intake port 4. However, in such a conventional structure, a part of the oil lifted up by the differential ring gear 3 is collected along the wall surface of the trans mission case 1 into the oil intake port 4. If a non-slip device is added, the gap between the wall of the transmission case and the diff ring gear 3 becomes large, and Most of the fried oil escapes to the transmission case side and does not reach the oil intake 4, which reduces the amount of oil supplied to the lubrication part, resulting in insufficient lubrication. there were.

【課題を解決するための手段】[Means for Solving the Problems]

本考案は上記従来の問題点に鑑み案出したものであって、確実良好にオイル取 入口へオイルを集めて潤滑部に十分なオイルを供給できる手動変速機の潤滑構造 を提供せんことを目的とし、その要旨は、トランスミッションケース内に溜めら れたオイルをデフリングギアの回転によりかき揚げ、該かき揚げられたオイルを 前記デフリングギアの周縁上部部位に配設されたオイル取入口で集油し、該オイ ル取入口に連通接続された導管を通してオイルを各潤滑部へ供給するように構成 した手動変速機において、前記デフリングギアの外周に、かき揚げられるオイル を前記オイル取入口へ導く断面コの字形のカバーを配設したことである。 The present invention has been made in view of the above conventional problems, and an object thereof is not to provide a lubrication structure for a manual transmission that can reliably collect oil at an oil intake port and supply sufficient oil to a lubricated portion. The gist is that the oil accumulated in the transmission case is lifted up by the rotation of the differential ring gear, and the lifted oil is collected at the oil inlet located at the upper peripheral portion of the differential ring gear, In a manual transmission configured to supply oil to each lubrication part through a conduit connected to the oil intake, a U-shaped cross-section that guides the oil to be lifted to the oil intake around the outer periphery of the differential ring gear. That is, a cover is provided.

【0004】[0004]

【作用】[Action]

デフリングギアの外周には断面コの字形のカバーが配設されているため、デフ リングギアの回転によりかき揚げられるオイルは、このカバーによりガイドされ て良好にオイル取入口側へ飛散し、オイル取入口内で良好にオイルを集油して潤 滑部に大量のオイルを供給することができる。 A cover with a U-shaped cross section is provided on the outer circumference of the diff ring gear, so the oil lifted up by the rotation of the diff ring gear is guided by this cover and scatters well to the oil intake side. It is possible to satisfactorily collect the oil inside and supply a large amount of oil to the lubrication part.

【実施例】【Example】

【0005】 以下、本考案の実施例を図面に基づいて説明する。図1は、自動車用手動変速 機の潤滑構造を示す概略構成図であり、図2はデフリングギア周辺の拡大構成図 であり、又、図3は図2の側面図である。 図において、トランスミッションケース1内にはオイルOが溜められており、 このオイルO内に下部部位を浸漬された状態でデフリングギア3が配設されてお り、このデフリングギア3は回転軸2に固設されたデフ本体3aの外周に形成さ れたものである。An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram showing a lubrication structure of a manual transmission for an automobile, FIG. 2 is an enlarged configuration diagram around a differential ring gear, and FIG. 3 is a side view of FIG. In the figure, an oil O is stored in a transmission case 1, and a diff ring gear 3 is arranged in a state in which a lower portion is immersed in the oil O. The diff ring gear 3 is attached to a rotary shaft 2. It is formed on the outer periphery of the fixed diff body 3a.

【0006】 また本例においては、このデフリングギア3の上部外周に断面コの字形のカバ ー6が配設されており、このカバー6はステー7,7を介しクラッチハウジング 又はトランスミッションケース1に固定されている。コの字形カバー6はその下 端部が前記オイルOの上面側に位置し、その上端部を、デフリングギア3の周縁 上部右側に上端を上方へ向けて開口されたオイル取入口4の上部に臨ませたもの であり、図3で示すようにカバー6の幅W2は前記デフリングギア3の幅W1よ り約10mm広いものに形成されており、また図2に示すようにカバー6の大径H 1はデフリングギア3の半径Rより約20mm大きくしてあり、またカバー6の小 径H2はデフリングギア3の半径Rよりも小さくなるように設定されている。Further, in this example, a cover 6 having a U-shaped cross section is arranged on the outer periphery of the upper portion of the differential ring gear 3, and the cover 6 is fixed to the clutch housing or the transmission case 1 via the stays 7, 7. Has been done. The lower end of the U-shaped cover 6 is located on the upper surface side of the oil O, and the upper end of the U-shaped cover 6 is located above the oil intake 4 which is open to the upper right of the peripheral edge of the differential ring gear 3 with its upper end facing upward. As shown in FIG. 3, the width W2 of the cover 6 is wider than the width W1 of the differential ring gear 3 by about 10 mm, and as shown in FIG. H 1 is set to be about 20 mm larger than the radius R of the differential ring gear 3, and the small diameter H 2 of the cover 6 is set to be smaller than the radius R of the differential ring gear 3.

【0007】 したがって、カバー6はデフリングギア3の外周縁の上部を約4分の1以上覆 蓋するものであり、デフリングギア3の回転によりかき揚げられるオイルOを良 好にガイドして、前記オイル取入口4へオイルを導くことができるものである。 そのため、カバー6に導かれて大量のオイルがオイル取入口4内に集油され、集 められたオイルは導管5を通して各潤滑部に供給され、潤滑部は大量のオイルに より良好に潤滑される。Therefore, the cover 6 covers the upper part of the outer peripheral edge of the differential ring gear 3 by about 1/4 or more, and properly guides the oil O lifted up by the rotation of the differential ring gear 3, and The oil can be guided to the intake port 4. Therefore, a large amount of oil is guided to the cover 6 and collected in the oil intake port 4, and the collected oil is supplied to each lubrication unit through the conduit 5, and the lubrication unit is better lubricated by the large amount of oil. It
