Description

本発明は、鞍乗型燃料電池車両に係り、特に、ラジエータの冷却性能を向上させることができるラジエータおよびその周辺構成を有する鞍乗型燃料電池車両に関する。   The present invention relates to a straddle-type fuel cell vehicle, and more particularly to a radiator capable of improving the cooling performance of a radiator and a straddle-type fuel cell vehicle having a peripheral configuration thereof.

従来から、水素と酸素の化学反応によって電気を発生する燃料電池を積載し、この燃料電池からの供給電力で走行する燃料電池車両が知られている。通常、このような燃料電池車両には、燃料電池が発生する熱を放熱するためのラジエータが備えられている。   2. Description of the Related Art Conventionally, there is known a fuel cell vehicle on which a fuel cell that generates electricity by a chemical reaction between hydrogen and oxygen is loaded and travels with power supplied from the fuel cell. Usually, such a fuel cell vehicle is provided with a radiator for radiating heat generated by the fuel cell.

特開２００７−５９１２７号公報 Patent Document 1 discloses a straddle-type fuel cell motorcycle in which another radiator is disposed in front of a head pipe of a vehicle body frame in addition to a radiator attached to a vehicle body frame on the rear side of a front wheel. ing.
JP 2007-59127 A

車室を有する４輪車等と異なり、余剰スペースの少ない鞍乗型車両においては、ラジエータも極力小型であることが好ましい。そして、走行風等が通過することで放熱を行うラジエータは、車体への配設位置等が冷却性能に与える影響が大きく、ラジエータを大型化することなく冷却性能を高める手法の開発が望まれている。   Unlike a four-wheeled vehicle or the like having a passenger compartment, in a saddle-ride type vehicle with a small excess space, the radiator is preferably as small as possible. And radiators that dissipate heat by passing running wind, etc., have a great influence on the cooling performance due to the installation position on the vehicle body, etc., and it is desired to develop a method for improving the cooling performance without increasing the size of the radiator Yes.

本発明の目的は、上記従来技術の課題を解決し、ラジエータの冷却性能の向上を可能とするラジエータおよびその周辺構成を有する鞍乗型燃料電池車両を提供することにある。   An object of the present invention is to solve the above-described problems of the prior art and provide a saddle type fuel cell vehicle having a radiator capable of improving the cooling performance of the radiator and its peripheral configuration.

前記目的を達成するために、本発明は、燃料電池からの供給電力で走行する鞍乗型燃料電池車両において、前記燃料電池からの供給電力を蓄える二次電池と、前記燃料電池の冷却水の放熱器であるラジエータとを具備し、前記ラジエータは、車体前後方向に対して前輪の斜め後方の左右に配設され、前記左右のラジエータの間に前記二次電池が設けられている点に第１の特徴がある。   In order to achieve the above object, the present invention relates to a secondary battery that stores power supplied from the fuel cell and a cooling water for the fuel cell in a saddle type fuel cell vehicle that travels with power supplied from the fuel cell. The radiator is a radiator, and the radiator is disposed on the left and right sides of the front wheel obliquely behind the front-rear direction of the vehicle body, and the secondary battery is provided between the left and right radiators. There is one feature.

また、前記二次電池と前記前輪との間に、薄板状のインナカウルが配設されている点に第２の特徴がある。   A second feature is that a thin plate-like inner cowl is disposed between the secondary battery and the front wheel.

また、車両前方を覆うカウリングと、前記ラジエータを囲繞する導風機構とを具備し、前記導風機構は、走行風の導入口および排出口を有すると共に、前記インナカウルの左右かつ前記カウリングの内側に配設されている点に第３の特徴がある。   A cowling that covers the front of the vehicle; and a wind guide mechanism that surrounds the radiator. The wind guide mechanism includes an inlet and a discharge port for running wind, and is provided on the left and right sides of the inner cowl and inside the cowling. The third feature is that it is disposed.

さらに、前記排出口には、前記ラジエータを通過後に車体外部に排出される風の向きを、運転者に向ける方向と車体外側に向ける方向との間で任意に変更できるルーバが備えられている点に第４の特徴がある。   Furthermore, the exhaust port is provided with a louver that can arbitrarily change the direction of the wind discharged to the outside of the vehicle body after passing through the radiator between a direction toward the driver and a direction toward the outside of the vehicle body. There is a fourth feature.

第１の発明によれば、燃料電池からの供給電力を蓄える二次電池と、燃料電池の冷却水の放熱器であるラジエータとを具備し、ラジエータは、車体前後方向に対して前輪の斜め後方の左右に配設され、左右のラジエータの間に二次電池が設けられているので、ラジエータに当たる走行風が前輪に遮られることがなく、ラジエータに効率よく走行風を当てることが可能となる。これにより、ラジエータの冷却性能が高められ、同じ冷却性能を確保しつつラジエータを小型化することが可能となる。また、ラジエータを左右に振り分けたことで確保される車幅方向中央のスペースを二次電池の配設スペースとして有効利用できるようになる。また、二次電池が車体前方寄りに配設されることで、前後輪の重量配分が後輪寄りになりやすい車体構成においても、前輪側の比率を増加させやすくなり、車体の前後重量バランスを向上させることが可能となる。   According to the first aspect of the present invention, the secondary battery that stores power supplied from the fuel cell and the radiator that is the radiator of the cooling water for the fuel cell are provided, and the radiator is obliquely rearward of the front wheel with respect to the longitudinal direction of the vehicle body. Since the secondary battery is provided between the left and right radiators, the traveling wind hitting the radiator is not blocked by the front wheels, and the traveling wind can be efficiently applied to the radiator. Thereby, the cooling performance of the radiator is enhanced, and the radiator can be downsized while ensuring the same cooling performance. In addition, the space in the center in the vehicle width direction secured by distributing the radiator to the left and right can be used effectively as the secondary battery installation space. In addition, by arranging the secondary battery closer to the front of the vehicle body, even in the vehicle body configuration where the weight distribution of the front and rear wheels tends to be closer to the rear wheel, it becomes easier to increase the ratio of the front wheel side, and the front-rear weight balance of the vehicle body It becomes possible to improve.

第２の発明によれば、二次電池と前輪との間に、薄板状のインナカウルが配設されているので、中央部において二次電池を衝撃から保護し、水や埃からも保護することが可能となる。   According to the second invention, since the thin plate-like inner cowl is disposed between the secondary battery and the front wheel, the secondary battery is protected from impact at the center, and is also protected from water and dust. Is possible.

第３の発明によれば、車両前方を覆うカウリングと、ラジエータを囲繞する導風機構とを具備し、導風機構は、走行風の導入口および排出口を有すると共に、インナカウルの左右かつカウリングの内側に配設されているので、導風機構によって、カウリング内側に配設されるラジエータに走行風を効率よく当てることができるようになる。   According to the third aspect of the invention, there is provided a cowling that covers the front of the vehicle and an air guide mechanism that surrounds the radiator. The air guide mechanism has an inlet and an exhaust port for traveling wind, and is provided on the left and right sides of the inner cowl and on the cowling. Since it is disposed on the inner side, the traveling wind can be efficiently applied to the radiator disposed on the inner side of the cowling by the wind guide mechanism.

第４の発明によれば、排出口には、ラジエータを通過後に車体外部に排出される風の向きを、運転者に向ける方向と車体外側に向ける方向との間で任意に変更できるルーバが備えられているので、ラジエータを通過して温められた排出風を運転者に当てて暖房に利用したり、車体外側に向けて運転者に当たらないように排出することを任意に選択できるようになる。   According to the fourth aspect of the invention, the exhaust port is provided with a louver that can arbitrarily change the direction of the wind discharged to the outside of the vehicle body after passing through the radiator between the direction toward the driver and the direction toward the outside of the vehicle body. Therefore, it is possible to arbitrarily select whether the exhausted air that has been warmed through the radiator is applied to the driver to be used for heating, or discharged toward the outside of the vehicle body so as not to hit the driver. .

左右のラジエータ６０Ｌ，６０Ｒは、前輪ＷＦおよびフロントフォーク３によって走行風が遮られて冷却効果が低下しないように、ラジエータコアが配設される平面部を車体中心側に傾けると共に、左右に振り分けられて取り付けられている。二次電池５１は、前輪ＷＦの車体後方側において、左右のラジエータ６０Ｌ，６０Ｒの間に配設されている。燃料電池車両１の車体は、車輪を除く大部分が外装部品としてのカウリング１７で覆われている。樹脂の薄板等で形成されるカウリング１７は、燃料電池車両１の外観を構成すると共に、車体内部への雨や埃等の侵入防止や走行風を整流する等の機能を有する。カウリング１７の車体前方側には、左右一対の開口部７１が形成されており、該開口部７１の略中央に外気を強制的にカウリング１７の内側に導入する電動ファン７０が配設されている。   The left and right radiators 60L and 60R are distributed to the left and right while tilting the plane portion on which the radiator core is disposed so that the cooling effect is not lowered by the front wheel WF and the front fork 3 being blocked by the traveling wind. Attached. The secondary battery 51 is disposed between the left and right radiators 60L and 60R on the vehicle body rear side of the front wheel WF. Most of the vehicle body of the fuel cell vehicle 1 except for the wheels is covered with a cowling 17 as an exterior part. The cowling 17 formed of a resin thin plate or the like constitutes the appearance of the fuel cell vehicle 1 and has functions such as preventing rain and dust from entering the vehicle body and rectifying running wind. A pair of left and right openings 71 are formed on the vehicle body front side of the cowling 17, and an electric fan 70 that forcibly introduces outside air into the inside of the cowling 17 is disposed at the approximate center of the opening 71. .

図５および図６は、図４の一部拡大図および図５のＡ−Ａ線断面図である。前記と同一符号は、同一または同等部分を示す。スクータ型の燃料電池車両１の車両前方側は、外装部品としてのカウリング１７で覆われている。そして、前輪ＷＦおよびフロントフォーク３の車体後方側には、樹脂の薄板等で形成され、前輪ＷＦによる水はね等が車体内部に侵入することを防ぐインナカウル２１が取り付けられている。カウリング１７やインナカウル２１は左右対称の形状とされるので、図５および図６では、車幅方向右側のみを示している。   5 and 6 are a partially enlarged view of FIG. 4 and a cross-sectional view taken along line AA of FIG. The same reference numerals as those described above denote the same or equivalent parts. The vehicle front side of the scooter type fuel cell vehicle 1 is covered with a cowling 17 as an exterior part. An inner cowl 21 is formed on the rear side of the front wheel WF and the front fork 3 with a resin thin plate or the like and prevents water splashes or the like from the front wheel WF from entering the vehicle body. Since the cowling 17 and the inner cowl 21 have a symmetrical shape, only the right side in the vehicle width direction is shown in FIGS.

前記カウリング１７の内側には、導風機構２２が配設されている。左右対称の導風機構２２には、走行風を導入するためのスリット２３，２４が形成されている。該スリット２３，２４は、前輪ＷＦおよびフロントフォーク３の車幅方向外側に位置し、走行風２７をほぼ直線的に導風機構２２に導入することができる。また、導風機構２２は、ラジエータ６０Ｌ，６０Ｒを囲繞する形状を有し、その車体後方側には導風板２２ａが取り付けられているので、スリット２３，２４から導入された走行風のほぼ全部をラジエータ６０Ｌ，６０Ｒに当てることが可能である。ラジエータを通過した走行風は、複数のルーバ２５を備える排出口６３から速やかに車体外部に排出される。このため、走行風の導入抵抗が低減され、ラジエータの冷却性能が一層高められる。   An air guide mechanism 22 is disposed inside the cowling 17. The symmetrical air guide mechanism 22 is formed with slits 23 and 24 for introducing running air. The slits 23 and 24 are located on the outer side in the vehicle width direction of the front wheel WF and the front fork 3 and can introduce the traveling wind 27 into the wind guide mechanism 22 almost linearly. Further, the wind guide mechanism 22 has a shape surrounding the radiators 60L and 60R, and since the wind guide plate 22a is attached to the rear side of the vehicle body, almost all of the traveling wind introduced from the slits 23 and 24 is provided. Can be applied to the radiators 60L and 60R. The traveling wind that has passed through the radiator is quickly discharged to the outside of the vehicle body from a discharge port 63 having a plurality of louvers 25. For this reason, the introduction resistance of the traveling wind is reduced, and the cooling performance of the radiator is further enhanced.

なお、本実施形態では、導風機構２２がインナカウル２１の左右側部に連結されているので、インナカウル２１には、二次電池５１を衝撃から保護し、水や埃からも保護すると共に、ラジエータに効率よく走行風を導く機能も与えられる。   In the present embodiment, since the air guide mechanism 22 is connected to the left and right sides of the inner cowl 21, the inner cowl 21 protects the secondary battery 51 from impact, protects it from water and dust, and also serves as a radiator. Is also provided with a function to efficiently guide the driving wind.

また、前記ルーバ２５は角度可変式とされており、駆動モータや手動によってその角度を変更することで、走行風の排出方向を変えることができる。これにより、走行風を運転者向き排出風２６ａに示すような向きにし、ラジエータを通過して温められた走行風を運転者に当てて暖房に利用したり、一方、車体外向き排出風２６ｂに示すように運転者に当たらないように排出することもできる。なお、スリット２３，２４にも可変式のルーバを取り付けて、インナカウル２１の内部に導入する走行風の量を任意に調整できるように構成してもよい。   The louver 25 is of a variable angle type, and the direction in which the traveling wind is discharged can be changed by changing the angle by a drive motor or manually. As a result, the traveling wind is directed as shown in the driver-oriented exhaust air 26a, and the traveling wind warmed by passing through the radiator is applied to the driver and used for heating. As shown, it can be discharged without hitting the driver. Note that a variable louver may be attached to the slits 23 and 24 so that the amount of traveling wind introduced into the inner cowl 21 can be arbitrarily adjusted.

二次電池５１は、左右の導風機構２２を連結する薄板状のインナカウル２１の裏面側に隣接して配設されている。本実施形態に係る燃料電池車両１においては、燃料電池３０や車体後端部の水素ボンベ１５、駆動モータを内装するスイングアーム１１等の重量物によって、前後輪の重量配分が後輪寄りになりやすいが、車体前方寄りに二次電池５１を配置することにより、前輪側の比率を増加させやすくなり、車体の前後重量バランスを向上させることができる。また、本実施形態に係る二次電池５１の配設位置は、ラジエータ６０Ｌ，６０Ｒを左右に振り分けたことで確保されるスペースが有効利用できると共に、重量物である二次電池５１が車幅方向中央の車体下部に配設されることとなり、車幅方向の重量バランスが保たれると共に、車体の重心位置が下げられ、より一層好適な位置である。   The secondary battery 51 is disposed adjacent to the back side of the thin plate-like inner cowl 21 that connects the left and right air guide mechanisms 22. In the fuel cell vehicle 1 according to the present embodiment, the weight distribution of the front and rear wheels is closer to the rear wheels due to heavy objects such as the fuel cell 30, the hydrogen cylinder 15 at the rear end of the vehicle body, and the swing arm 11 that houses the drive motor. Although it is easy to arrange the secondary battery 51 closer to the front of the vehicle body, it becomes easier to increase the ratio of the front wheels, and the front-rear weight balance of the vehicle body can be improved. In addition, the secondary battery 51 according to the present embodiment can be arranged in such a way that a space secured by distributing the radiators 60L and 60R to the left and right can be used effectively, and the heavy secondary battery 51 is disposed in the vehicle width direction. It is arranged at the lower part of the vehicle body in the center, maintaining a weight balance in the vehicle width direction and lowering the center of gravity of the vehicle body, which is a more suitable position.

上記したように、本発明に係る鞍乗型燃料電池車両によれば、車体前後方向に対して前輪の斜め後方の左右にラジエータ６０Ｌ，６０Ｒを配設したので、ラジエータに当たる走行風が前輪ＷＦに遮られず、ラジエータに効率よく走行風を当てることが可能となる。これにより、ラジエータの冷却性能が高められ、同じ冷却性能を確保しつつ小型化を図ることが可能となる。また、ラジエータを左右に振り分けたことで確保される車幅方向中央のスペースを二次電池の配設スペースとして有効利用できるようになる。   As described above, according to the straddle-type fuel cell vehicle according to the present invention, the radiators 60L and 60R are disposed on the left and right sides of the front wheels obliquely rearward with respect to the longitudinal direction of the vehicle body. Without being obstructed, the running wind can be efficiently applied to the radiator. As a result, the cooling performance of the radiator is enhanced, and it is possible to reduce the size while ensuring the same cooling performance. In addition, the space in the center in the vehicle width direction secured by distributing the radiator to the left and right can be used effectively as the secondary battery installation space.

なお、ラジエータや導風機構、インナカウルの形状、導風機構のスリットおよびルーバの数や形状等は、上記した実施形態に限られず、種々の変更が可能である。例えば、導風機構に導入した走行風の一部を二次電池の冷却に使用したり、導風機構のルーバに、上下左右に風向きを変更できるものを適用してもよい。   Note that the shape of the radiator, the air guide mechanism, the inner cowl, the number and shape of the slits and louvers of the air guide mechanism are not limited to the above-described embodiment, and various changes can be made. For example, a part of the traveling wind introduced into the wind guide mechanism may be used for cooling the secondary battery, or a louver of the wind guide mechanism that can change the wind direction vertically and horizontally may be applied.

また、燃料電池車両の形態は、自動二輪車のほか３／４輪車等であってもよく、燃料電池、水素貯蔵手段、過給機、加湿機、電圧変換器、二次電池、ラジエータ等の構成部品の形態や配置も種々の変更が可能である。   Further, the form of the fuel cell vehicle may be a 3/4 wheel vehicle or the like in addition to the motorcycle, such as a fuel cell, a hydrogen storage means, a supercharger, a humidifier, a voltage converter, a secondary battery, a radiator, etc. Various changes can be made to the form and arrangement of the components.
