　鞍乗型車両は、小型軽量であることが求められる。シリーズハイブリッド式鞍乗型車両についても、小型軽量が求められる。従って、シリーズハイブリッド式鞍乗型車両は、バッテリ、エンジン駆動電力供給ユニット及び駆動モータを搭載するため、これらの要素をコンパクトに配置することが求められる。これに対し、エンジン駆動電力供給ユニットは、発電用エンジンを備えているため、シリーズハイブリッド式鞍乗型車両において各要素を密接に配置すると、発電用エンジンの振動及び熱が他の要素に伝達してしまう可能性がある。本発明の目的は、発電用エンジンの振動及び熱による影響を低減しつつ、コンパクトに構成した、シリーズハイブリッド式鞍乗型車両を提供することである。 Straddle-type vehicles are required to be compact and lightweight. Series hybrid straddle-type vehicles are also required to be compact and lightweight. Therefore, since the series hybrid straddle-type vehicle is equipped with a battery, an engine-driven power supply unit, and a drive motor, it is required to arrange these elements in a compact manner. On the other hand, since the engine-driven power supply unit is equipped with an engine for power generation, if each element is closely arranged in a series hybrid straddle-type vehicle, the vibration and heat of the engine for power generation will be transmitted to other elements. There is a possibility that SUMMARY OF THE INVENTION An object of the present invention is to provide a series hybrid straddle-type vehicle that is compact while reducing the effects of vibration and heat of a power generation engine.
　本発明者は、シリーズハイブリッド式鞍乗型車両に搭載の要素をコンパクトに配置することについて検討した。特許文献１のシリーズハイブリッド式鞍乗型車両は、バッテリとエンジン駆動電力供給ユニットとが、近接して配置されている。ここで、エンジン駆動電力供給ユニットの発電用エンジンは、振動及び熱が発生する。特許文献１のシリーズハイブリッド式鞍乗型車両では、発電用エンジンの振動及び熱が、バッテリに伝わる可能性がある。また、発電用エンジンの振動については、車体フレームを介してバッテリに伝わる可能性もある。バッテリに振動及び熱が伝わると、例えば充電及び放電等のバッテリの性能に影響が及ぶ可能性がある。 The inventor studied compact arrangement of mounted elements in a series hybrid straddle-type vehicle. In the series hybrid straddle-type vehicle disclosed in Patent Document 1, a battery and an engine-driven power supply unit are arranged close to each other. Here, the power generation engine of the engine-driven power supply unit generates vibration and heat. In the series hybrid straddle-type vehicle disclosed in Patent Document 1, there is a possibility that the vibration and heat of the power generation engine are transmitted to the battery. In addition, there is a possibility that the vibration of the power generating engine will be transmitted to the battery via the vehicle body frame. Vibration and heat transfer to the battery can affect battery performance, such as charging and discharging.
　そこで、本発明者は、エンジン駆動電力供給ユニットの発電用エンジンから発生する振動及び熱を考慮しつつ、シリーズハイブリッド式鞍乗型車両の車体をコンパクト化することについて検討した。この検討の中で、本発明者は、振動を許容するように発電用エンジンを車体フレームに支持し、エンジンとバッテリとの間に振動を許容する隙間を設けることにより、発電用エンジンの振動及び熱が、バッテリに伝達するのを抑制するという知見を得た。具体的には、発電用エンジンを、車体フレームに対する発電用エンジンの振動を許容するように構成される支持機構を介して車体フレームに支持し、バッテリを、下記（Ａ）から（Ｃ）の全てを満たすように、車体フレームに、揺動可能に又は固定的に、支持する。ここで、前記（Ａ）から（Ｃ）は、
（Ａ）バッテリは、シリーズハイブリッド式鞍乗型車両の前後方向で発電用エンジンよりも前に配置されること、
（Ｂ）バッテリの少なくとも一部は、シリーズハイブリッド式鞍乗型車両を前後方向に見て発電用エンジンと重なりを有するように配置されること、
（Ｃ）バッテリは、発電用エンジンと間隙を空けてシリーズハイブリッド式鞍乗型車両の前後方向に対向するように配置され、間隙は、振動の方向において、支持機構により許容される振動の最大振幅と前記振動の方向における前記バッテリの最大振幅との合計よりも大きいこと

　本明細書では、新しいシリーズハイブリッド式鞍乗型車両について説明する。以下の説明では、説明の目的で、本発明の完全な理解を提供するために多数の具体的な詳細を述べる。しかしながら、当業者には、これらの特定の詳細無しに本発明を実施できることが明らかである。本開示は、本発明の例示として考慮されるべきであり、本発明を以下の図面または説明によって示される特定の実施形態に限定することを意図するものではない。 This specification describes a new series hybrid straddle-type vehicle. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the invention. However, it will be obvious to those skilled in the art that the present invention may be practiced without these specific details. The present disclosure should be considered exemplary of the invention and is not intended to limit the invention to the specific embodiments illustrated by the following drawings or description.
　鞍乗型車両（ｓｔｒａｄｄｌｅｄ　ｖｅｈｉｃｌｅ）とは、運転者がサドルに跨って着座する形式のビークルをいう。鞍乗型車両としては、例えば、モペット型、オフロード型、オンロード型の自動二輪車が挙げられる。また、鞍乗型車両としては、自動二輪車に限定されず、例えば、自動三輪車、ＡＴＶ（Ａｌｌ－Ｔｅｒｒａｉｎ　Ｖｅｈｉｃｌｅ）等であってもよい。自動三輪車は、２つの前輪と１つの後輪とを備えていてもよく、１つの前輪と２つの後輪とを備えていてもよい。鞍乗型車両の駆動輪は、後輪であってもよく、前輪であってもよい。また、鞍乗型車両の駆動輪は、後輪及び前輪の双方であってもよい。また、鞍乗型車両は、リーン姿勢で旋回可能に構成されていることが好ましい。リーン姿勢で旋回可能に構成された鞍乗型車両は、カーブの中心に傾いた姿勢で旋回するように構成される。これにより、リーン姿勢で旋回可能に構成された鞍乗型車両は、旋回時にビークルに加わる遠心力に対抗する。 A straddled vehicle is a vehicle in which the driver sits astride the saddle. Straddle-type vehicles include, for example, moped-type, off-road-type, and on-road-type motorcycles. Moreover, the straddle-type vehicle is not limited to a motorcycle, and may be, for example, a three-wheeled motor vehicle, an ATV (All-Terrain Vehicle), or the like. A motor tricycle may have two front wheels and one rear wheel, or may have one front wheel and two rear wheels. The driving wheels of the straddle-type vehicle may be the rear wheels or the front wheels. Also, the drive wheels of the straddle-type vehicle may be both the rear wheels and the front wheels. Moreover, it is preferable that the straddle-type vehicle is configured to be able to turn in a lean posture. A straddle-type vehicle that is configured to turn in a lean posture is configured to turn in a posture that is inclined toward the center of a curve. As a result, the straddle-type vehicle configured to be able to turn in a lean posture resists the centrifugal force applied to the vehicle during turning.
　車体フレームは、鞍乗型車両の骨格をなし、バッテリ、エンジン駆動電力供給ユニット及び駆動モータ等の鞍乗型車両の搭載部品等を支持する。車体フレームは、ヘッドパイプと、ヘッドパイプに固定された桁部とを有する。車体フレームは、例えば、シングルグレードル型、ダブルグレードル型、ダイヤモンド型、及びモノコック型等が挙げられるが、これらに限定されない。車体フレームは、フレーム本体と剛性を有する部品とが一体となって、前輪及び後輪からの荷重を受ける。 The vehicle body frame forms the skeleton of the straddle-type vehicle and supports mounted parts of the straddle-type vehicle such as the battery, the engine drive power supply unit, and the drive motor. The body frame has a head pipe and a girder fixed to the head pipe. Examples of the body frame include, but are not limited to, single gradle type, double gradle type, diamond type, and monocoque type. The vehicle body frame receives loads from the front wheels and the rear wheels by integrating the frame body and rigid parts.
　発電用エンジンは、例えば、高負荷領域と低負荷領域とを有するエンジンである。発電用エンジンは、例えば、４ストロークエンジンである。４ストロークエンジンは、４ストロークの間に、高負荷領域と低負荷領域とを有する。高負荷領域と低負荷領域とを有する４ストロークエンジンは、例えば、単気筒エンジンである。また、高負荷領域と低負荷領域とを有する。高負荷領域と低負荷領域とを有する４ストロークエンジンは、例えば、２気筒エンジン、不等間隔燃焼型３気筒エンジン、又は、不等間隔燃焼型４気筒エンジンである。高負荷領域と低負荷領域とを有する４ストロークエンジンは、１サイクル７２０度の間に１８０度以上の連続不燃焼区間を含む。高負荷領域と低負荷領域とを有する４ストロークエンジンは、例えば、気筒数が３以上の等間隔燃焼型エンジンは含まない。４ストロークエンジンは、例えば、３つより少ない気筒を有するエンジンである。本開示の一実施形態において、４ストロークエンジンは、例えば、単気筒エンジン又は２気筒エンジンである。２気筒エンジンは、２つの気筒を有する不等間隔燃焼エンジンであってもよい。２つの気筒を有する不等間隔燃焼エンジンとして、例えばＶ型エンジンが挙げられる。シリンダは、起立姿勢又は倒伏姿勢のいずれで設けられてもよい。好ましい実施形態において、シリンダは、倒伏姿勢で設けられる。「シリンダが起立姿勢を有する」とは、シリンダが、シリーズハイブリッド式鞍乗型車両の直立状態においてシリンダが上方を向くように設定されていることをいう。エンジンが複数のシリンダを有する場合、少なくとも１つのシリンダが起立姿勢を有していればよい。ここで、上方を向くとは、シリーズハイブリッド式鞍乗型車両の上下方向においてシリンダがエンジンの回転軸から上方に延び、且つ、シリンダ孔の中心軸が鉛直線に対して成す傾斜角が特定角度以内であることをいう。特定角度は、例えば、４５度であってもよく、３０度であってもよい。なお、傾斜角は、中心軸と鉛直線との双方が含まれる平面を基準として定められる。また、「シリンダが倒伏姿勢」を有するとは、シリンダが、シリーズハイブリッド式鞍乗型車両の直立状態においてシリンダが前方を向くように設定されていることをいう。エンジンが複数のシリンダを有する場合、少なくとも１つのシリンダが倒伏姿勢を有していればよい。ここで、前方を向くとは、シリーズハイブリッド式鞍乗型車両の前後方向においてシリンダがエンジンの回転軸から前方に延び、且つ、シリンダ孔の中心軸が鉛直線に対して成す傾斜角が４５度以上１３５度以下であることをいう。なお、傾斜角は、中心軸と鉛直線との双方が含まれる平面を基準として定められる。 A power generation engine is, for example, an engine that has a high load region and a low load region. The power generation engine is, for example, a 4-stroke engine. A four-stroke engine has a high load region and a low load region during the four strokes. A four-stroke engine having a high load region and a low load region is, for example, a single cylinder engine. It also has a high load area and a low load area. A 4-stroke engine having a high load region and a low load region is, for example, a 2-cylinder engine, a unequal combustion 3-cylinder engine, or an unequal combustion 4-cylinder engine. A four-stroke engine having a high load region and a low load region includes a continuous non-combustion section of 180 degrees or more during one cycle of 720 degrees. A four-stroke engine having a high-load region and a low-load region does not include, for example, an even-spaced combustion engine with three or more cylinders. A four-stroke engine is, for example, an engine with less than three cylinders. In one embodiment of the present disclosure, the four-stroke engine is, for example, a single-cylinder engine or a two-cylinder engine. A two-cylinder engine may be a differential combustion engine having two cylinders. An example of an unequal interval combustion engine having two cylinders is a V-type engine. The cylinder may be provided in either a standing or lying down position. In a preferred embodiment, the cylinder is provided in a laid down position. "The cylinder has an upright posture" means that the cylinder is set to face upward in the upright state of the series hybrid straddle-type vehicle. If the engine has multiple cylinders, at least one cylinder should have a standing posture. Here, "facing upward" means that the cylinder extends upward from the rotation axis of the engine in the vertical direction of the series hybrid saddle-ride type vehicle, and the inclination angle formed by the center axis of the cylinder hole with respect to the vertical line is a specific angle. It means to be within The specific angle may be, for example, 45 degrees or 30 degrees. Note that the tilt angle is determined with reference to a plane that includes both the central axis and the vertical line. Further, "the cylinder has a lying posture" means that the cylinder is set to face forward in the upright state of the series hybrid straddle-type vehicle. If the engine has multiple cylinders, at least one cylinder should be in the laid down position. Here, facing forward means that the cylinder extends forward from the rotation axis of the engine in the longitudinal direction of the series hybrid saddle-ride type vehicle, and the inclination angle formed by the central axis of the cylinder hole with respect to the vertical line is 45 degrees. More than 135 degrees or less. Note that the tilt angle is determined with reference to a plane that includes both the central axis and the vertical line.
　発電機は、例えば永久磁石式の始動発電機である。発電機は、例えば永久磁石を使用しないモータであってもよい。永久磁石式の発電機は、例えば、ブラシレスモータである。ブラシレスモータは、整流子を有さないモータである。発電機は、エンジンによって駆動され発電するモータジェネレータである。発電機は、エンジンを始動する始動モータとして機能してもよい。発電機は、これに限られない。永久磁石式の発電機は、例えば、ブラシ付き直流モータでもよい。ブラシレスモータは、例えば、アウターロータ型でもよく、また、インナーロータ型でもよい。また、ブラシレスモータは、ラジアルギャップ型でなく、アキシャルギャップ型でもよい。また、発電機は、例えばロータに永久磁石を有さないタイプでもよい。 The generator is, for example, a permanent magnet starter generator. The generator may be, for example, a motor that does not use permanent magnets. A permanent magnet generator is, for example, a brushless motor. A brushless motor is a motor that does not have a commutator. A generator is a motor generator that is driven by an engine to generate electricity. The generator may act as a starter motor to start the engine. A generator is not restricted to this. The permanent magnet generator may be, for example, a brushed DC motor. The brushless motor may be, for example, an outer rotor type or an inner rotor type. Also, the brushless motor may be of the axial gap type instead of the radial gap type. The generator may also be of a type that does not have permanent magnets in the rotor, for example.
　支持機構は、車体フレームに発電用エンジンに支持するための接続部品又はこれらの接続部品の組み合わせである。支持機構は、発電用エンジンの振動を許容しつつ車体フレームに発電用エンジンを支持する。発電用エンジンの振動を許容しつつ発電用エンジンを車体フレームに支持する接続部品は、例えば発電用エンジンとフレームとを接続する弾性部材である。発電用エンジンの振動を許容しつつ発電用エンジンを車体フレームに支持する接続部品の組み合わせは、例えばリンク機構と弾性部材との組み合わせである。弾性部材は、例えばゴムブッシュである。弾性部材は、例えば内外筒ブッシュ、スグリブッシュ又はダンパーゴムであってもよい。弾性部材は、弾性を有する部材である。弾性部材は、例えば、緩衝部材、制振部材、防振部材等を含む。リンク機構は、例えばリンク板と回転支持部との組み合わせである。回転支持部は、例えばベアリングにより構成されたベアリング支持部である。回転支持部は、ベアリングに替えて、例えばリンク機構が回転可能に構成された弾性体による支持であってもよい。 The support mechanism is a connection part or a combination of these connection parts for supporting the power generation engine on the vehicle body frame. The support mechanism supports the power generating engine on the vehicle body frame while allowing the power generating engine to vibrate. A connection component that supports the power generation engine on the vehicle body frame while allowing vibration of the power generation engine is, for example, an elastic member that connects the power generation engine and the frame. A combination of connection parts for supporting the power generation engine on the vehicle body frame while allowing vibration of the power generation engine is, for example, a combination of a link mechanism and an elastic member. The elastic member is, for example, a rubber bush. The elastic member may be, for example, an inner/outer sleeve bush, a currant bush, or a damper rubber. The elastic member is a member having elasticity. The elastic member includes, for example, a cushioning member, a damping member, a vibration isolating member, and the like. A link mechanism is, for example, a combination of a link plate and a rotation support. The rotation support is, for example, a bearing support made up of bearings. Instead of the bearing, the rotation support may be supported by an elastic body configured to allow the link mechanism to rotate, for example.
　バッテリと発電用エンジンとの間隙は、空気とは限らない。隙間にゴムのような弾性材料が充填されてもよい。更に、バッテリと発電用エンジンとの間隙は、ゴムと空気の隙間とを有してもよい。 The gap between the battery and the power generation engine is not necessarily air. The gap may be filled with an elastic material such as rubber. Further, the gap between the battery and the power generating engine may have a gap of rubber and air.
　バッテリと発電用エンジンとが前後方向に「対向する」とは、例えばエンジンとバッテリとの間隙に空気が存在する構成を含む。但し、「対向する」構成は特に限定されず、例えば、エンジンとバッテリとの間隙に、バッテリ及びエンジンのための断熱部材及び弾性部材といったエンジン及びバッテリの機能に直接関係する部材が存在する構成でもよい。但し、「対向する」構成は、例えばモータ又は車体フレームといった、エンジン又はバッテリの機能に直接関係しない部品が存在する構成を含まない。 The phrase "facing" the battery and the power generation engine in the front-rear direction includes, for example, a configuration in which air exists in the gap between the engine and the battery. However, the "opposed" configuration is not particularly limited, for example, a configuration in which a member directly related to the function of the engine and the battery, such as a heat insulating member and an elastic member for the battery and the engine, is present in the gap between the engine and the battery. good. However, "facing" configurations do not include configurations in which there are parts that are not directly related to the function of the engine or battery, such as motors or body frames.
　本発明によれば、発電用エンジンの振動及び熱の発生を許容しつつ、コンパクトに構成した、シリーズハイブリッド式鞍乗型車両を提供することができる。 According to the present invention, it is possible to provide a series hybrid saddle-riding vehicle that is compact while allowing the vibration and heat generation of the power generation engine.
