A series hybrid straddle-type vehicle described in Patent Document 1 includes a battery, an engine-driven power supply unit, and a drive motor, and runs by the drive motor supplied with power from the battery and the engine-driven power supply unit.

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.

In this study, the present inventors have found that by supporting the power generating engine on the vehicle body frame so as to allow vibration and providing a gap between the engine and the battery to allow vibration, the vibration of the power generating engine and the We have found that heat is suppressed from being transferred to the battery. Specifically, the power generation engine is supported on the vehicle body frame via a support mechanism configured to allow vibration of the power generation engine with respect to the vehicle body frame, and the battery is subjected to all of (A) to (C) below. is pivotably or fixedly supported on the vehicle body frame so as to satisfy Here, the above (A) to (C) are

As a result, it is possible to suppress the vibration of the power generation engine from being transmitted to the vehicle body frame. Also, by arranging the battery as shown in (A) and (B), the battery and the generator engine are arranged in the longitudinal direction of the series hybrid straddle-type vehicle, thereby suppressing the horizontal and vertical sizes. can be done. Further, by arranging as shown in (C), it is possible to suppress transmission of permissible vibration of the power generation engine to the battery, and suppress transmission of heat of the power generation engine to the battery. That is, the gap between the power generation engine and the battery in (C) is a gap for suppressing transmission of vibration of the power generation engine to the battery, and a gap for suppressing transmission of heat from the power generation engine to the battery. can also serve as a gap between By supporting the power generation engine and the battery on the vehicle body frame in this way, the series hybrid straddle-type vehicle can be configured compactly while allowing vibration and heat generation of the power generation engine. Compactness can be achieved while reducing the influence of vibration and heat. Note that the gap may be partially or wholly included in the front and rear inter-wheel region, for example. This makes it possible to realize a more compact arrangement.

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.

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.

図6のシリーズハイブリッド式鞍乗型車両6の発電用エンジン20は、第一領域A1に含まれるシリンダ21の体積が、第二領域A2に含まれるシリンダ21の体積よりも少なくなり、且つ発電機30が部分的又は全体的に第一領域A1に含まれるように、偏心的に配置される。ここで、第一領域A1及び第二領域A2は、シリーズハイブリッド式鞍乗型車両6を含む空間を、左右方向LRにおけるシリーズハイブリッド式鞍乗型車両6の中心Cを通り上下方向UD及び前後方向FBに広がる中心面で2つに区分することにより定義される2つの領域を指す。
また、図6のシリーズハイブリッド式鞍乗型車両6は、ラジエータ23と、走行風通路26と、空冷フィン43と、排風通路27と有する。ラジエータ23は、バッテリ40の前方Fに配置される。走行風通路26は、走行風が第一領域A1においてバッテリ40の横を通るように構成される。空冷フィン43は、走行風通路26に露出するようにバッテリ40に設けられる。排風通路27は、ラジエータ23の排風を第二領域A2においてバッテリ40の横に流すように構成される。 In thepower generation engine 20 of the series hybrid straddle-type vehicle 6 of FIG. 30 is arranged eccentrically so that it is partially or wholly contained in the first area A1. Here, the first area A1 and the second area A2 extend the space including the series hybrid straddle-type vehicle 6 in the vertical direction UD and the front-rear direction through the center C of the series hybrid straddle-type vehicle 6 in the left-right direction LR. Refers to the two regions defined by the two divisions on the central plane that spans the FB.
The series hybrid saddle-ride type vehicle 6 of FIG. The radiator 23 is arranged in front F of the battery 40 . Traveling wind passage 26 is configured to allow the traveling wind to pass beside battery 40 in first region A1. The air cooling fins 43 are provided on the battery 40 so as to be exposed to the running air passage 26 . The exhaust passage 27 is configured to allow the exhaust air from the radiator 23 to flow to the side of the battery 40 in the second area A2.
また、図6のシリーズハイブリッド式鞍乗型車両6は、ラジエータ23と、走行風通路26と、空冷フィン43と、排風通路27と有する。ラジエータ23は、バッテリ40の前方Fに配置される。走行風通路26は、走行風が第一領域A1においてバッテリ40の横を通るように構成される。空冷フィン43は、走行風通路26に露出するようにバッテリ40に設けられる。排風通路27は、ラジエータ23の排風を第二領域A2においてバッテリ40の横に流すように構成される。 In the
The series hybrid saddle-
走行風通路26は、例えば車体フレーム10の側面をカウル261で覆うことにより生じた第一領域A1におけるバッテリ40及び発電用エンジン20と、カウル261との間の隙間を利用する。排風通路27は、例えば前後方向FBにおけるラジエータ23の後方向Bに、整流板271を設けることにより確保する。整流板271により、ラジエータ23からの排風を第二領域A2に導くことができる。なお、排風通路27は、ラジエータ23の後に排風を第二領域A2に導く排風口を設けることにより構成してもよい。
