Description

本発明は主として自動車の変速機の潤滑構造に関する。   The present invention mainly relates to a lubricating structure for an automobile transmission.

従来、急発進時に変速用歯車に対して十分に潤滑油が供給されるトランスミッションの潤滑構造として、車両発進時の慣性力によって後方へ移動しようとする潤滑油を堰き止めるための反射壁部と、堰き止められた潤滑油が変速用歯車の歯面に供給されるように該反射壁部から歯面に向けて所定の角度θで傾斜して延在する供給壁部とから形成される反射構造壁を有するものが提供されている（特許文献１参照）。   Conventionally, as a transmission lubrication structure in which lubricating oil is sufficiently supplied to a gear for gear shifting at the time of sudden start, a reflection wall portion for damming the lubricating oil trying to move backward by inertial force at the time of vehicle start, A reflection structure formed from a supply wall portion that extends at an angle θ from the reflection wall portion toward the tooth surface so that the blocked lubricating oil is supplied to the tooth surface of the transmission gear. What has a wall is provided (refer patent document 1).

特開２００３−１１３９２９号公報（第２−３頁、第１図）JP 2003-113929 A (page 2-3, FIG. 1)

一般に、変速機のケーシング内の潤滑油は回転する歯車によって攪拌されているので、潤滑油を後側に移動させる力が加えられている場合には、反射構造壁より前側の潤滑油が歯車の攪拌力によって該反射構造壁を超えて後側に移動する量に対して、反射構造壁より後側の潤滑油が該反射構造壁を乗り越えて前側に移動する量は少なく、そのため、反射構造壁によって堰き止められ該反射構造壁より前側に蓄えられていた潤滑油は、歯車の攪拌力によって該反射構造壁を超えて徐々に後側に移動することとなる。
したがって上記従来の構成では、長時間にわたって潤滑油を後側に移動させる力が加えられる場合、例えば自動車が登坂走行を長時間行なう場合には、反射構造壁より前側に蓄えられていた潤滑油のほとんどが、歯車の攪拌力によって該反射構造壁を超えて後側に移動してしまい、反射構造壁より前側の歯車の潤滑不良が発生するおそれがあるという問題があった。 Generally, since the lubricating oil in the casing of the transmission is agitated by a rotating gear, when a force for moving the lubricating oil to the rear side is applied, the lubricating oil on the front side of the reflecting structure wall is Compared to the amount that moves behind the reflecting structure wall to the rear side by the stirring force, the amount of the lubricating oil on the rear side from the reflecting structure wall moves over the reflecting structure wall and moves to the front side. The lubricating oil that has been dammed up and stored on the front side of the reflecting structure wall gradually moves to the rear side beyond the reflecting structure wall by the stirring force of the gears.
Therefore, in the above-described conventional configuration, when a force that moves the lubricating oil to the rear side for a long time is applied, for example, when an automobile runs on an uphill for a long time, the lubricating oil stored on the front side of the reflecting structure wall is reduced. Most of the gears move to the rear side beyond the reflecting structure wall due to the stirring force of the gears, and there is a problem in that poor lubrication of the gears on the front side of the reflecting structure wall may occur.

本発明は上記従来の課題を解決するための手段として、変速機(1) の複数個の歯車(7) を潤滑油によって潤滑する変速機(1) の潤滑構造であって、該潤滑油の少なくとも一部が後側に移動するのを堰き止める潤滑油堰き止め部材(5) と、該潤滑油を該潤滑油堰き止め部材(5) より前側に供給する潤滑油供給手段とを有する変速機(1) の潤滑構造を提供するものである。
変速機(1) のケーシング(2) 下部にはバッフルプレート(3) が設置されており、上記潤滑油堰き止め部材は、該バッフルプレート(3) の前部に立設された潤滑油堰止め板(5) であることが望ましい。
また、該潤滑油堰止め板(5) より前部において該バッフルプレート(3) には切欠部(8) が設けられており、該ケーシング(2) の内周面には前後方向に沿ってガイドリブ(11)が凸設されており、上記潤滑油供給手段は、該ケーシング(2) の内周面を伝って流下する潤滑油を該ガイドリブ(11)によって受止して前側へガイドし、該ガイドされた潤滑油を該バッフルプレート(3) の切欠部(8) を介して該潤滑油堰止め板(5) より前側に供給するものであることが望ましい。
更に、該潤滑油堰止め板(4,5) は前後一対に立設されており、該前後一対の潤滑油堰止め板(4,5) の間には油溜り部(6) が画設されていることが望ましい。
また更に、該切欠部(8) は、該前後一対の潤滑油堰止め板(4,5) の間において設けられており、該ガイドリブ(11)によってガイドされた潤滑油を該バッフルプレート(3) の切欠部(8) を介して該油溜り部(6) に供給することが望ましい。 The present invention provides a lubricating structure of a transmission (1) that lubricates a plurality of gears (7) of a transmission (1) with lubricating oil as means for solving the above-described conventional problems. A transmission having a lubricating oil damming member (5) for blocking at least a part of the oil from moving to the rear side, and a lubricating oil supply means for supplying the lubricating oil to the front side from the lubricating oil damming member (5) The lubricating structure of (1) is provided.
A baffle plate (3) is installed in the lower part of the casing (2) of the transmission (1), and the lubricating oil damming member is a lubricating oil damming standing on the front of the baffle plate (3). The plate (5) is desirable.
The baffle plate (3) is provided with a notch (8) in front of the lubricating oil weir plate (5), and the casing (2) has an inner peripheral surface along the front-rear direction. Guide ribs (11) are provided so that the lubricating oil supply means receives the lubricating oil flowing down along the inner peripheral surface of the casing (2) by the guide ribs (11) and guides it to the front side. It is desirable that the guided lubricating oil is supplied to the front side of the lubricating oil damming plate (5) through the notch (8) of the baffle plate (3).
Further, the lubricating oil weir plates (4, 5) are erected in a pair, and an oil reservoir (6) is provided between the pair of front and rear lubricating oil weir plates (4, 5). It is desirable that

The lubricating oil flowing down along the inner peripheral surface of the pipe is received by the guide rib (11) and guided to the front side, and the lubricating oil is guided through the notch (8) of the baffle plate (3) to the rear dam plate. (5) Since it can be supplied to the front side, that is, the oil sump (6), when a force to move the lubricating oil to the rear side for a long time is applied, for example, when a car runs uphill for a long time Even so, there is no loss of lubricating oil in front of the rear weir plate (5), and the gear (7) in front of the rear weir plate (5), that is, the oil reservoir (6) It is possible to prevent the occurrence of poor lubrication of the front gear (7) at the same longitudinal position.
