本発明は、走行ミッションケースに、車軸の収納ケース
を連設した走行用伝動構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a traveling transmission structure in which an axle storage case is connected to a traveling transmission case.
かかる走行用伝動構造においては、ミッションケース内
に収納したギヤ群の潤滑のため、ミッションケース内に
潤滑油を貯留することになり、そして、従来では、前記
潤滑油を冷却するに、ミッションケースの外面部からの
放熱により行なわせるようにしていた。In such a driving transmission structure, lubricating oil is stored in the transmission case to lubricate the gear group housed in the transmission case. Conventionally, in order to cool the lubricating oil, the transmission case is heated. This was done by radiating heat from the outer surface.
従来技術によれば、ミッションケースの外面部のみを放
熱面に利用して潤滑油を冷却していたため、潤滑油を充
分に冷却することができず、油温上昇により潤滑油を早
期に劣化させてしまう不都合があった。According to conventional technology, only the outer surface of the transmission case was used as a heat dissipation surface to cool the lubricating oil, which made it impossible to cool the lubricating oil sufficiently, causing the lubricating oil to deteriorate prematurely due to an increase in oil temperature. There was an inconvenience.
ちなみに、潤滑油冷却のための特別なオイルクーラを設
置する手段が考えられるが、全体構造が複雑になる不利
があり、実用上に難点があった。Incidentally, installing a special oil cooler for cooling the lubricating oil has been considered, but this has the disadvantage of complicating the overall structure, which is difficult in practice.
本発明は、上記実情に鑑みてなされたものであって、そ
の目的は、本来構成を有効利用した簡単な改造で、潤滑
油を効率よく冷却できるようにする点にある。The present invention has been made in view of the above-mentioned circumstances, and its purpose is to enable efficient cooling of lubricating oil by a simple modification that makes effective use of the original structure.
本発明の特徴構成は、前記ミッションケース内の潤滑油
を前記収納ケース内に循環流動させる油路を設けると共
に、前記車軸あるいはそれて連設のギヤに、前記循環流
動のためのポンプ作用部を備えさせてある点にあり、そ
の作用及び効果は次の通りである。The characteristic configuration of the present invention is that an oil passage is provided for circulating the lubricating oil in the transmission case into the storage case, and a pump acting part for the circulating flow is provided on the axle or a gear connected thereto. The functions and effects are as follows.
すなわち、ミッションケース内の潤滑油を車軸収納ケー
ス内に循環流動させることによって、車軸収納ケースの
外面部をも放熱面に利用しながら潤滑油を冷却すること
ができ、しかも、車軸あるいはそれに連設のギヤを利用
した簡素な構成で、尚滑油循環流動のためのポンプ作用
部を備えさせるようにしである。In other words, by circulating the lubricating oil inside the transmission case into the axle storage case, the lubricating oil can be cooled while also using the outer surface of the axle storage case as a heat dissipation surface. It has a simple structure using gears, and is also equipped with a pumping section for circulating oil.
したがって、本来的に備えられる車軸収納ケースの外面

体構造が複雑にな（゛ ることを抑制する状態で
油温上昇による潤滑油の早期劣化を防止して、一層便利
に使用できる走行川伝ｗＪ構造を得るに至った。Therefore, the lubricating oil can be efficiently cooled by a simple modification that effectively uses the outer surface of the axle storage case as a heat dissipation surface, thereby reducing the complexity of the overall structure. We have achieved a structure that prevents early deterioration of the lubricating oil due to increases in oil temperature while suppressing this phenomenon, making it even more convenient to use.
