Description

ストラドルドビークルStraddled vehicle
　本発明は、ストラドルドビークルに関する。 The present invention relates to a straddled vehicle.
　ストラドルドビークルの軽量化が要求されている。ストラドルドビークルの軽量化を図るために、例えば、繊維強化樹脂によって構成された部品を備えたストラドルドビークルが提案されている。繊維強化樹脂によって構成された部品を備えたストラドルドビークルとして、例えば特許文献１に開示されている自動二輪車が知られている。 There is a demand for weight reduction of straddled vehicles.

　本発明者は、ストラドルドビークルの部品を繊維強化樹脂によって構成することについて、軽量化だけではなく耐久性の観点からも検討した。その結果、軽量化及び耐久性の両方を考慮した場合、ストラドルドビークルにおける繊維強化樹脂製の部品の採用が難しいことが分かった。 The present inventor examined the construction of the straddled vehicle parts with fiber reinforced resin from the viewpoint of durability as well as weight reduction. As a result, it has been found that it is difficult to adopt a part made of fiber reinforced resin in a straddled vehicle when considering both weight reduction and durability.
　本発明は、ストラドルドビークルにおいて、軽量化及び耐久性の両立を図りつつ、繊維強化樹脂製の部品を採用可能な構成を得ることを目的とする。 The object of the present invention is to obtain a configuration in which a part made of fiber reinforced resin can be adopted in a straddled vehicle while achieving both weight reduction and durability.
　本発明者は、鋭意検討の結果、軽量化及び耐久性を考慮した場合、ストラドルドビークルにおける繊維強化樹脂製の部品の採用が難しいことが分かった。 As a result of intensive studies, the present inventor has found that it is difficult to adopt a fiber-reinforced resin part in a straddled vehicle when considering weight reduction and durability.
　その理由は、以下のとおりである。 The reason is as follows.
　まず、本発明者は、ストラドルドビークルに多くの繊維強化樹脂製の部品を採用することにより、車両を軽量化できると考えた。そのため、本発明者は、ストラドルドビークルの様々な部品を、繊維強化樹脂製の部品に置き換えることを検討した。その検討の過程において、本発明者は、繊維強化樹脂製の部品の耐久性について検討した。検討の結果、繊維強化樹脂製の部品が磨耗した場合、内部の繊維が露出することが分かった。 First, the present inventor considered that the weight of the vehicle can be reduced by adopting many fiber reinforced resin parts in the straddled vehicle. Therefore, the present inventor considered replacing various parts of the straddled vehicle with parts made of fiber reinforced resin. In the course of the study, the present inventor examined the durability of the parts made of fiber reinforced resin. As a result of the investigation, it was found that when the fiber reinforced resin part was worn, the internal fibers were exposed.
　これに対し、本発明者は、繊維強化樹脂製の部品の耐久性を確保できるように、該部品の表面に塗装を厚く塗布することを考えた。このように繊維強化樹脂製の部品の表面に塗装を厚く塗布することにより、繊維強化樹脂製の部品が磨耗して繊維が露出することを抑制できた。しかしながら、このように繊維強化樹脂製の部品の表面に塗装を厚く塗布した場合には、繊維強化樹脂製の部品であるにもかかわらず、十分な軽量化の効果が得られないことが分かった。すなわち、繊維強化樹脂製の部品では、軽量化及び耐久性の両立を図ることは難しいことが分かった。 On the other hand, the present inventor considered applying a thick coating on the surface of the component so as to ensure the durability of the component made of fiber reinforced resin. Thus, by applying a thick coating on the surface of the fiber reinforced resin part, it was possible to suppress the fiber reinforced resin part from being worn out and exposed to the fiber. However, it has been found that when the coating is applied thickly on the surface of the fiber reinforced resin part as described above, a sufficient weight reduction effect cannot be obtained even though the part is made of fiber reinforced resin. . That is, it has been found that it is difficult to achieve both weight reduction and durability in a fiber reinforced resin part.
　本発明者は、繊維強化樹脂製の部品の耐久性について、繰り返し検討を行った。その結果、以下のことが分かった。 The inventor repeatedly examined the durability of fiber reinforced resin parts. As a result, the following was found.
　ストラドルドビークルは、乗員が跨って乗る乗り物である。そのため、ストラドルドビークルに用いられる部品のうち、磨耗が促進される部分は、車両の右側面または左側面で、且つ、シートに着座した乗員の下半身が接触する部分であることが分かった。また、乗員に限らず、荷ひも、ヘルメット及びバッグなどの付属品が車両に接触する部分でも、前記部品の磨耗が促進されることも分かった。 The straddled vehicle is a vehicle on which the passenger rides. For this reason, it has been found that, among the parts used in the straddled vehicle, the portion where wear is promoted is the portion on the right or left side of the vehicle and the lower body of the occupant seated on the seat. It has also been found that the wear of the parts is promoted not only in the occupant but also in parts where accessories such as luggage, helmets and bags contact the vehicle.
　さらに、前記磨耗が促進される部分は、ストラドルドビークルの車種毎に決まることも分かった。 Furthermore, it was found that the portion where the wear is promoted is determined for each vehicle type of the straddled vehicle.
　このように磨耗が促進される部分が予め分かっていれば、前記部品を繊維強化樹脂によって構成した場合に、表面に塗装を施すのではなく、繊維強化樹脂製の部品において樹脂を部分的に厚くすることにより、前記部品の重量の増加を抑えつつ耐久性を向上できることが分かった。 In this way, if the part where wear is promoted is known in advance, when the part is made of fiber reinforced resin, the resin is partially thickened in the part made of fiber reinforced resin instead of coating the surface. It was found that the durability can be improved while suppressing an increase in the weight of the component.
　以上の検討結果に基づいて、本発明者は、ストラドルドビークルにおいて、繊維強化樹脂製の部品における繊維強化樹脂層の最外層よりも車両外方に磨耗許容層を設けるとともに、該磨耗許容層を、車両の左方向または右方向から見て、位置によって厚みが異なるように形成する構成を見出した。 Based on the above examination results, the present inventor provided a wear-allowable layer in the straddled vehicle outside the vehicle rather than the outermost layer of the fiber-reinforced resin layer in the fiber-reinforced resin part. The present inventors have found a configuration in which the thickness varies depending on the position when viewed from the left or right direction of the vehicle.
　具体的には、本発明者は、以下のような構成に想到した。 Specifically, the present inventor has conceived the following configuration.
　本発明の一実施形態に係るストラドルドビークルは、前輪と、後輪と、車両の左右方向の中央に位置し、乗員が着座するシートと、前記乗員が前記シートに着座した状態で左足を載せる左ステップと、前記乗員が前記シートに着座した状態で右足を載せる右ステップと、樹脂と該樹脂を強化する強化繊維とを含む繊維強化樹脂層を有し且つ少なくとも一部が前記車両の左側外表面を構成する繊維強化樹脂製部品を、少なくとも一つ有するストラドルドビークル左側外表面部と、樹脂と該樹脂を強化する強化繊維とを含む繊維強化樹脂層を有し且つ少なくとも一部が前記車両の右側外表面を構成する繊維強化樹脂製部品を、少なくとも一つ有するストラドルドビークル右側外表面部と、を備える。前記ストラドルドビークル左側外表面部は、前記繊維強化樹脂層の最左外層と車両左側外表面との間に、前記樹脂と一体形成され、且つ、前記車両左側外表面が擦れた際に磨耗し、前記車両を左方向から見て、前記車両の左右方向の厚みが相対的に大きい部分と小さい部分とを含むストラドルドビークル左側磨耗許容層を有し、かつ、前記ストラドルドビークル右側外表面部は、前記繊維強化樹脂層の最右外層と車両右側外表面との間に、前記樹脂と一体形成され、且つ、前記車両右側外表面が擦れた際に磨耗し、前記車両を右方向から見て、前記車両の左右方向の厚みが相対的に大きい部分と小さい部分とを含むストラドルドビークル右側磨耗許容層を有する。 A straddled vehicle according to an embodiment of the present invention has a front wheel, a rear wheel, a seat positioned in the center of the vehicle in the left-right direction, and a seat on which an occupant is seated, and a left foot in a state where the occupant is seated on the seat. A left step; a right step of placing a right foot in a state where the occupant is seated on the seat; a fiber reinforced resin layer including a resin and a reinforcing fiber that reinforces the resin, and at least a part of the left outer side of the vehicle The vehicle has a straddled vehicle left outer surface portion having at least one fiber reinforced resin part constituting the surface, a fiber reinforced resin layer including a resin and a reinforced fiber for reinforcing the resin, and at least a part of the vehicle A straddled vehicle right outer surface portion having at least one part made of fiber reinforced resin constituting the right outer surface. The left outer surface portion of the straddled vehicle is integrally formed with the resin between the leftmost outer layer of the fiber reinforced resin layer and the vehicle left outer surface, and wears when the vehicle left outer surface is rubbed. A straddled vehicle left-side wear-permissible layer including a relatively large portion and a small portion of the vehicle in the left-right direction when the vehicle is viewed from the left, and the straddled vehicle right-side outer surface portion Is formed integrally with the resin between the rightmost outer layer of the fiber reinforced resin layer and the outer right surface of the vehicle, and wears when the outer right surface of the vehicle is rubbed, and the vehicle is viewed from the right. And a straddled vehicle right-side wear-allowing layer including a portion having a relatively large and small thickness in the left-right direction of the vehicle.
　これにより、車両の左側外表面が、シートに着座した乗員の下半身と接触して擦れた場合、繊維強化樹脂層の最左外層と車両左側外表面との間に樹脂と一体形成されたストラドルドビークル左側磨耗許容層が磨耗する。また、車両の右側外表面が、シートに着座した乗員の下半身と接触して擦れた場合、繊維強化樹脂層の最右外層と車両右側外表面との間に樹脂と一体形成されたストラドルドビークル右側磨耗許容層が磨耗する。よって、繊維強化樹脂層が磨耗して強化繊維が露出することを防止できる。 As a result, when the left outer surface of the vehicle contacts and rubs against the lower body of the occupant seated on the seat, the straddle formed integrally with the resin between the leftmost outer layer of the fiber reinforced resin layer and the left outer surface of the vehicle The left side wearable layer of the vehicle wears.

The outer resin layers 22b, 14b, 8d and the outer resin layers 22e, 24b, 8g, which are straddled vehicle right-side wear-resistant layers, gradually wear out.
　換言すれば、本実施形態に係る車両１では、乗員が車両１に跨った際に車両１において乗員Ｐの下半身が触れる部分（図２から図６における斜線部分）に、炭素繊維強化樹脂によって構成された部品が配置されている。このように、乗員の身体が触れる部分に炭素繊維強化樹脂製の部品が配置されている場合、上述のように乗員の身体との接触によって前記部品の樹脂の磨耗が促進される。 In other words, in the vehicle 1 according to the present embodiment, a portion (hatched portion in FIGS. 2 to 6) where the lower body of the occupant P touches the vehicle 1 when the occupant straddles the vehicle 1 is configured with carbon fiber reinforced resin.

　これに対し、前記部品の表面に塗装を施すことが考えられるが、塗装の耐久性を確保するために該塗装を厚く塗ると、炭素繊維強化樹脂製の部品を用いたにもかかわらず、十分な軽量化の効果が得られない。 On the other hand, it is conceivable that the surface of the part is coated. However, if the coating is applied thickly in order to ensure the durability of the coating, it is sufficient even though the part made of carbon fiber reinforced resin is used. A light weight reduction effect cannot be obtained.
　そこで、本実施形態では、車両１の炭素繊維強化樹脂製の部品において、乗員Ｐが車両１に跨った際に乗員Ｐの下半身が接触する部分では、外表面に位置する外側樹脂層の厚みを大きくする。このように、炭素繊維強化樹脂製の部品において、外表面に位置する外側樹脂層の厚みを車両１の位置によって変えることにより、車両１の重量の増加を抑制しつつ、炭素繊維強化樹脂製の部品の耐久性を向上させることができる。 Therefore, in the present embodiment, in the parts made of carbon fiber reinforced resin of the vehicle 1, the thickness of the outer resin layer located on the outer surface is the portion where the lower body of the occupant P contacts when the occupant P straddles the vehicle 1. Enlarge.

To do. As a result, when the vehicle 1 is viewed from the side, the carbon fiber reinforced resin component includes a portion having a large thickness and a small portion in the vehicle left-right direction in the outer resin layer located on the outer surface.
　図２から図７に示すように、例えば、サイドカバー２２の外側樹脂層２２ｂ，２２ｅのうち、乗員が車両１に跨った状態で該乗員の下半身が接触する部分、すなわち、車両１の左右方向においてサイドカバー２２の端部における外側樹脂層２２ｂ，２２ｅの樹脂の厚みは、外側樹脂層２２ｂ，２２ｅの他の部分の厚みよりも大きい。すなわち、外側樹脂層２２ｂ，２２ｅは、車両１の左右方向においてサイドカバー２２の左右の端部に位置し、且つ、他の部分に比べて樹脂の厚みが大きい肉厚部２２ｇ，２２ｈを有する。肉厚部２２ｇ，２２ｈは、外側樹脂層２２ｂ，２２ｅにおいて、乗員Ｐが車両１に跨った状態で該乗員の下半身が接触する部分に設けられている。 As shown in FIGS. 2 to 7, for example, in the outer resin layers 22 b and 22 e of the side cover 22, the part where the lower body of the occupant contacts with the occupant straddling the vehicle 1, that is, the left-right direction of the vehicle 1. The thickness of the resin of the outer resin layers 22b and 22e at the end of the side cover 22 is larger than the thickness of the other portions of the outer resin layers 22b and 22e.
