Description
本発明は、電動二輪車の技術分野に関し、より詳しくは、電動二輪車の動力組立部材の給油システム（A lubrication system of a power assembly of an electric scooter）に関する。 The present invention relates to the technical field of electric motorcycles, and more particularly, to an lubrication system for a power assembly of an electric scooter.
従来の電動二輪車は主にモーターを動力源とし、伝動装置によって車輪に伝動させて車両を走行させている。前記モーター及び伝動装置のギアセットは高速回転状態となるため、適切な潤滑油を使用して潤滑性及び冷却効果を提供する必要がある。 2. Description of the Related Art Conventional electric motorcycles mainly use a motor as a power source, and the vehicle travels by being transmitted to wheels by a transmission device. Since the motor and the gear set of the transmission are in a high-speed rotation state, it is necessary to provide lubricity and a cooling effect by using an appropriate lubricating oil.
前記モーター及び前記減速ギアセットは共に独立した部材または装置であるため、各々独立した潤滑油流路により潤滑性及び冷却効果を提供する必要がある。このため、潤滑油の流路が大きくなり、潤滑性及び冷却効果が理想的にはならなかった。また、潤滑油が流動することで気泡が生じてしまい、すぐに気泡を除去しなければ流動した潤滑油が気泡と混じり合って潤滑油の流動性が低下し、部材に対する冷却効果も低下した。 Since the motor and the reduction gear set are independent members or devices, it is necessary to provide lubrication and cooling effects by independent lubricating oil channels. Therefore, the flow path of the lubricating oil becomes large, and the lubricity and the cooling effect are not ideal. In addition, bubbles flow due to the flow of the lubricating oil, and if the bubbles are not removed immediately, the flowing lubricating oil mixes with the bubbles to reduce the fluidity of the lubricating oil and the cooling effect on the members.
そこで、本発明者は上記の欠点が改善可能と考え、鋭意検討を重ねた結果、合理的かつ効果的に課題を改善する本発明の提案に到った。 Therefore, the present inventor considered that the above-mentioned disadvantages can be improved, and as a result of intensive studies, came to a proposal of the present invention that rationally and effectively improves the problem.
かかる従来の実情に鑑みて、本発明は、電動二輪車の動力組立部材の給油システムを提供することを目的とする。つまり、潤滑油の流路が短く、即時気泡を除去できる効果を有する。 In view of such a conventional situation, an object of the present invention is to provide a fuel supply system for a power assembly member of an electric motorcycle. In other words, the lubricating oil flow path is short and has the effect of immediately removing bubbles.
また、本発明の他の目的は、電動二輪車の動力組立部材の給油システムを提供する。つまり、互いに噛合しトルクを伝達する２つのギアがその噛合位置で潤滑性及び冷却効果を直接提供し、トルクの伝達をよりスムーズにする。 Another object of the present invention is to provide an oil supply system for a power assembly member of an electric motorcycle. That is, the two gears that mesh with each other and transmit the torque directly provide lubrication and cooling effects at the meshing position, and make the torque transmission smoother.
上記課題を解決する本発明は、ケース内に従動ギアシャフトダクトに対応するケースダクトが形成され、前記従動ギアシャフトダクトは従動ギアシャフトの軸方向内部に形成される。また、ベアリングシートダクトは前記ケース内に形成されると共に従動ギアベアリングシート及び駆動ギアベアリングシートに連結され、前記ベアリングシートダクトは前記従動ギアシャフトダクトに連通されることを特徴とする。 According to the present invention for solving the above problems, a case duct corresponding to a driven gear shaft duct is formed in a case, and the driven gear shaft duct is formed inside an axial direction of the driven gear shaft. A bearing seat duct is formed in the case and connected to the driven gear bearing seat and the drive gear bearing seat, and the bearing seat duct is communicated with the driven gear shaft duct.
よって、前記潤滑油は前記ケースダクトから前記従動ギアシャフトダクトに向けて流れ、前記従動ギアシャフトダクトから前記従動ギアベアリングシートに流出し、且つ前記ベアリングシートダクトを通過させて前記駆動ギアベアリングシートに向けて流れる。これにより、潤滑油の流路の短縮、及び潤滑性及び冷却効果の向上を達成させる。 Therefore, the lubricating oil flows from the case duct toward the driven gear shaft duct, flows out of the driven gear shaft duct to the driven gear bearing seat, and passes through the bearing seat duct to the drive gear bearing seat. Flow toward This achieves shortening of the lubricating oil flow path and improvement in lubricity and cooling effect.
本発明によれば、従来の潤滑油の流路は長すぎるため冷却効果が優れず、すぐに気泡を除去できないという欠点を解決させる。 According to the present invention, it is possible to solve the drawback that the conventional lubricating oil flow path is too long, so that the cooling effect is not excellent and the air bubbles cannot be removed immediately.

図１１に示されるように、前記各ダクトの構成及び位置に基づいて、本発明では潤滑油（エンジンオイル）が前記ケースダクト３０を経て前記従動ギアシャフトダクト４０に向けて流れる。前記潤滑油は前記従動ギアシャフトダクト４０から流出した後に前記従動ギアベアリングシート５０に注入されてから前記ベアリングシートダクト６０に流入する。潤滑油は前記ベアリングシートダクト６０を通過させて前記駆動ギアベアリングシート５２内に注入される。前記電動モーター及び前記従動ギアの実際の配置方向に基づいて、前記気泡除去部８０がケースの下方に位置され、よって、潤滑油が前記気泡除去部８０に向けて流れ、且つ前記第２案内ダクト部７４を経て前記気泡除去部８０に進入する。前記気泡除去部８０が複数の前記リブ（図示省略）を有するため、潤滑油が流動することで生じる気泡が即時除去される。その後、適切なオイルポンプによって潤滑油が前記ケースダクト３０に送り込まれる。 As shown in FIG. 11, in the present invention, lubricating oil (engine oil) flows toward the driven gear shaft duct 40 via the case duct 30 based on the configuration and position of each duct. The lubricating oil flows out of the driven gear shaft duct 40, is injected into the driven gear bearing seat 50, and then flows into the bearing seat duct 60. The lubricating oil passes through the bearing seat duct 60 and is injected into the drive gear bearing seat 52. Based on the actual arrangement direction of the electric motor and the driven gear, the bubble removing unit 80 is located below the case, so that the lubricating oil flows toward the bubble removing unit 80 and the second guide duct The air enters the bubble removing unit 80 via the unit 74. Since the bubble removing unit 80 has the plurality of ribs (not shown), bubbles generated by the flow of the lubricating oil are immediately removed. Thereafter, lubricating oil is fed into the case duct 30 by an appropriate oil pump.
さらに、図７、図８、図１０及び図１１に示されるように、潤滑油は前記ベアリングシートダクト６０を通過中に前記段状フランジ６６にぶつかり、部分的な潤滑油が前記ジェットボア６８から噴出し、且つ前記潤滑油が前記駆動ギア２２と前記従動ギア１６との噛合位置で作用する。噴出した潤滑油は前記第１案内ダクト部７２から前記従動ギアベアリングシート５０に戻される。 Further, as shown in FIGS. 7, 8, 10, and 11, the lubricating oil collides with the stepped flange 66 while passing through the bearing seat duct 60, and a partial lubricating oil is discharged from the jet bore 68. The lubricating oil is ejected and acts at the meshing position between the drive gear 22 and the driven gear 16. The spouted lubricating oil is returned from the first guide duct portion 72 to the driven gear bearing seat 50.
本実施形態はフィルターキット９０を備える。前記フィルターキット９０は軸方向にパイプ９４が配設されるフィルター９２を備える（図１２参照）。前記パイプ９４は前記ケースダクト３０内に挿入される。これにより、前記ケースダクト３０に進入した潤滑油の清浄度が高く保たれる。 This embodiment includes a filter kit 90. The filter kit 90 includes a filter 92 in which a pipe 94 is provided in the axial direction (see FIG. 12). The pipe 94 is inserted into the case duct 30. As a result, the cleanliness of the lubricating oil that has entered the case duct 30 is kept high.
図１３によると、上蓋用スロット１００は前記ケース１０に形成され、且つ上蓋１０２は前記上蓋用スロット１００内に装設される。また、前記上蓋用スロット１００の壁面には第３案内ダクト部１０４を有し、前記上蓋１０２内部には上蓋ダクト１０６を有する。前記上蓋ダクト１０６の一端は前記ケースダクト３０に位置を合わせ、前記上蓋ダクト１０６の他端は前記上蓋用スロット１００内部に向けられる。前記第３案内ダクト部１０４は前記従動ギアシャフト２４の前記第１ボア４４に対応する。即ち、潤滑油が前記ケースダクト３０から前記上蓋ダクト１０６に進入する。潤滑油は前記上蓋ダクト１０６から送出された後、前記第１ボア４４から前記軸方向部４２に進入する。 Referring to FIG. 13, an upper lid slot 100 is formed in the case 10, and an upper lid 102 is installed in the upper lid slot 100. In addition, a third guide duct portion 104 is provided on a wall surface of the upper cover slot 100, and an upper cover duct 106 is provided inside the upper cover 102. One end of the upper cover duct 106 is aligned with the case duct 30, and the other end of the upper cover duct 106 is directed to the inside of the upper cover slot 100. The third guide duct portion 104 corresponds to the first bore 44 of the driven gear shaft 24. That is, the lubricating oil enters the upper lid duct 106 from the case duct 30. After the lubricating oil is discharged from the upper lid duct 106, it enters the axial portion 42 from the first bore 44.
図１４に示されるように、潤滑油は前記ケースダクト３０を経て前記上蓋ダクト１０６に流れて送出された後に前記従動ギアシャフトダクト４０に向けて流れる。前記潤滑油は前記従動ギアシャフトダクト４０から流出した後に前記従動ギアベアリングシート５０に注入されると共に前記ベアリングシートダクト６０に流入する。潤滑油は前記ベアリングシートダクト６０を通過させて前記駆動ギアベアリングシート５２内に注入され、且つ前記第２案内ダクト部７４を経て前記気泡除去部８０に進入する。前記気泡除去部８０が複数の前記リブ（図示省略）を有することによって、潤滑油の流動によって生じた気泡が即時除去される。その後、前記潤滑油がポンプにより前記ケースダクト３０に送り込まれる。 As shown in FIG. 14, the lubricating oil flows through the case duct 30 to the upper lid duct 106 and is sent out, and then flows toward the driven gear shaft duct 40. After the lubricating oil flows out of the driven gear shaft duct 40, it is injected into the driven gear bearing seat 50 and flows into the bearing seat duct 60. The lubricating oil is injected into the drive gear bearing seat 52 through the bearing seat duct 60, and enters the bubble removing unit 80 via the second guide duct 74. Since the bubble removing section 80 has the plurality of ribs (not shown), bubbles generated by the flow of the lubricating oil are immediately removed. Thereafter, the lubricating oil is pumped into the case duct 30 by a pump.
以上の説明のように、前記電動モーター１８及び前記従動ギア１６が同じケース１０内に統合されると共に隣接し合うことによって、前記潤滑油流路システムの経路が短縮して潤滑性及び冷却効果が高まる。また、本実施形態では潤滑油が前記駆動ギア２２と前記従動ギア１６との噛合箇所に向けて案内されて噴射されるため、２つのギア間の摩擦が軽減するのみならず、２つの前記ギアの相対運動によって生じる熱量も低下する。 As described above, since the electric motor 18 and the driven gear 16 are integrated and adjacent to each other in the same case 10, the path of the lubricating oil flow path system is shortened, and the lubricating property and the cooling effect are improved. Increase. Further, in the present embodiment, the lubricating oil is guided and injected toward the meshing portion between the drive gear 22 and the driven gear 16, so that not only the friction between the two gears is reduced, but also the two gears are used. The amount of heat generated by the relative motions of the two is also reduced.
前記気泡除去部８０及び前記リブ８２は潤滑油の流動によって生じる気泡を即時除去させ、これにより前記潤滑油が循環中にも好ましい流動性を保つ。また、潤滑油は前記駆動ギアベアリングシート５２及び前記従動ギアベアリングシート５０に向けて流れるため、前記従動ギアベアリング５４及び前記駆動ギアベアリング５６が好ましい潤滑効果及び低減効果を獲得する。 The bubble removing portion 80 and the rib 82 immediately remove bubbles generated by the flow of the lubricating oil, thereby maintaining the preferable fluidity even during the circulation of the lubricating oil. In addition, since the lubricating oil flows toward the driving gear bearing sheet 52 and the driven gear bearing sheet 50, the driven gear bearing 54 and the driving gear bearing 56 obtain favorable lubrication and reduction effects.
上述の実施形態は本発明の技術思想及び特徴を説明するためのものにすぎず、当該技術分野を熟知する者に本発明の内容を理解させると共にこれをもって実施させることを目的とし、本発明の特許請求の範囲を限定するものではない。従って、本発明の精神を逸脱せずに行う各種の同様の効果をもつ改良又は変更は、後述の請求項に含まれるものとする。 The above-described embodiment is merely for explaining the technical idea and features of the present invention, and is intended to allow those skilled in the art to understand and implement the present invention, It does not limit the scope of the claims.
