Description

  The present invention relates to a motorcycle equipped with a horn.

  The horn of a motorcycle must reach a person or the like in front of the motorcycle so that the sound volume reaches a predetermined amount or more. Therefore, not only the volume generated by the horn itself but also the mounting position of the horn is important. In general, the mounting position of the horn is preferably the front side of the vehicle body.

  Conventionally, a motorcycle having a so-called full cowl is known. A motorcycle equipped with a full cowl is provided with a cover that covers almost the entire front portion of the vehicle body. In a motorcycle equipped with a full cowl, a front cowl that covers the front of the steering wheel, an inner panel that is disposed from the upper part of the front wheel to the rear, and a side cover that is disposed on the left and right outer sides of the inner panel and extends rearward. Some have

  However, in a motorcycle equipped with a full cowl including an inner panel, if the horn is arranged in front of the inner panel, the flow of traveling wind on the front side of the inner panel is disturbed by the horn. Therefore, there is a possibility that traveling wind for cooling cannot be effectively supplied to components requiring cooling disposed on the rear side of the inner panel (for example, an engine in an air-cooled engine, a radiator in a water-cooled engine, etc.).

Patent Document 1 describes a motorcycle in which an opening for a horn is formed on an inclined surface of an upper portion of an inner panel, and the horn and the inclined surface of the inner panel are arranged on substantially the same surface. With such an arrangement, the horn does not protrude from the inner panel, so that the turbulence of the traveling wind on the front side of the inner panel can be suppressed.
Japanese Utility Model Publication No. 63-13392

  Japanese Patent Application Laid-Open No. H10-228707 describes that the warning sound of the horn is not reduced because the horn faces the opening of the rectifying surface of the inner panel. However, since the opening is located immediately behind the front fork, there is a possibility that the warning sound of the horn may actually be reduced.

  The present invention has been made in view of such points, and an object of the present invention is to provide a motorcycle that can easily secure a sufficient volume of a horn.

  The motorcycle according to the present invention includes a head pipe, a front fork supported by the head pipe, a front wheel rotatably supported by a lower end portion of the front fork, a front cowl covering the front of the head pipe, An inner panel disposed behind the front wheel below the front cowl, left and right side covers disposed on the left and right outer sides of the inner panel, and a position overlapping the inner panel in a front view. And at least a part of the horn disposed outwardly in the left-right direction of the front fork.

  ADVANTAGE OF THE INVENTION According to this invention, the motorcycle which is easy to ensure the sound volume of a horn is realizable.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<Embodiment 1>
As shown in FIG. 1, the motorcycle 10 according to the embodiment of the present invention includes a vehicle body frame 24 having a head pipe 11. A fuel tank 26 and a seat 28 are supported on the body frame 24. A rear arm 38 is swingably supported on the vehicle body frame 24 via a pivot shaft 36. A rear wheel 34 is rotatably supported at the rear end portion of the rear arm 38.

  An engine 30 is suspended from the body frame 24. In the present embodiment, the engine 30 is a water-cooled single cylinder engine. However, the engine 30 may be an air-cooled engine or a multi-cylinder engine. The engine 30 includes an engine body 30a and a cylinder 30b that extends obliquely forward and upward from the engine body 30a. As shown in FIG. 7, a water pump 30c is attached to the right side of the cylinder 30b when viewed from the front. Further, as shown in FIG. 2, an exhaust pipe 33 is disposed on the left side of the vehicle as viewed from the front. The exhaust pipe 33 is connected to the cylinder 30b. A muffler 35 is attached to the rear end of the exhaust pipe 33.

  As shown in FIG. 1, a front fork 14 is rotatably supported on the head pipe 11. A handle 16 is attached to the top of the front fork 14. A front wheel 12 is rotatably supported at the lower portion of the front fork 14. A fender 18 is attached to the front fork 14 so as to cover the upper and rear of the front wheel 12.

  A front cowl 20 is provided in front of the head pipe 11. The front cowl 20 is provided with a headlight 20a and a windbreak plate 20b. An inner panel 42 is disposed below the front cowl 20 so as to extend from the upper side to the rear side of the front wheel 12. In the present embodiment, since the fender 18 is provided above and behind the front wheel 12, the inner panel 42 is disposed from above the fender 18 to the rear. Left and right side covers 22 extending rearward are provided on the left and right outer sides of the inner panel 42, respectively.

  In the description of the present specification, the left and right directions refer to the left and right directions when the motorcycle 10 is viewed from the front. Therefore, the left and right directions are opposite to the left and right directions viewed from the rider seated on the seat 28 of the motorcycle 10. The left side and the right side of the vehicle mean the left side and the right side from the center line M1 (see FIG. 2) of the vehicle.

  FIG. 3 is a front view of the inner panel 42. As shown in FIG. 3, the inner panel 42 is formed with a main opening 72 extending left and right across the center of the vehicle (ie, the center line M1). In the present specification, the “opening of the inner panel” refers to a hole formed in the inner panel or a bent portion formed in the periphery. The main opening 72 is a portion that swells downward in the upper portion of the inner panel 42. In the present embodiment, the main opening 72 is formed above the intermediate position in the vertical direction of the inner panel 42 (that is, the center line M2). The main opening 72 is an opening through which traveling wind from the front passes rearward, and plays a role of supplying traveling wind to the radiator 40 in the present embodiment.

  Ventilation openings 52L and 52R and ventilation openings 50L and 50R are formed below the main opening 72 in the inner panel 42. The ventilation opening 52L and the ventilation opening 52R are formed at symmetrical positions. Further, the ventilation opening 50L and the ventilation opening 50R are formed at symmetrical positions. The ventilation openings 52L and 52R are formed above the ventilation openings 50L and 50R. These ventilation openings 50L, 50R, 52L, and 52R have a function of supplying traveling air to components requiring cooling (for example, the engine 30) disposed behind the inner panel 42.

  Ventilation opening 50L. Air guide surfaces 54L, 54R, 58L, and 58R that extend toward the front of the vehicle are formed around 50R, 52L, and 52R, respectively. These air guide surfaces 54L, 54R, 58L, 58R form a duct shape that becomes narrower from the front to the rear of the vehicle, thereby effectively feeding the traveling wind to the rear of the inner panel 42. . A reinforcing rib 56L is formed between the ventilation opening 52L and the ventilation opening 50L. A reinforcing rib 56R is also formed between the ventilation opening 52R and the ventilation opening 50L. In addition, a reinforcing rib 74 extending left and right is formed below the main opening 72.

  On both the left and right sides of the main opening 72 of the inner panel 42, air guide walls 68L and 68R that rise to the front end of the side cover 22 are formed. A horn opening 60 is formed in the right air guide wall 68R. The horn opening 60 is formed on the side of the main opening 72. The horn opening 60 is formed above an intermediate position in the vertical direction of the inner panel 42. In the present embodiment, the horn opening 60 is not more than ¼ of the vertical length of the inner panel 42 from the upper end 42 a of the inner panel 42. Formed in position. However, as described later, the position of the horn opening 60 can be variously modified and is not limited to the above position.

  Although the size of the horn opening 60 is not particularly limited, the horn opening 60 is smaller than the main opening 72 in the present embodiment. The horn opening 60 may be larger or smaller than any one of the ventilation openings 50L, 50R, 52L, and 52R, and may be the same size. The shape of the horn opening 60 may be a rectangular shape, or may be other shapes such as a circular shape or an oval shape.

  As shown in FIGS. 4 and 5, a cylindrical portion 61 extending rearward is provided on the back side of the horn opening 60 in the inner panel 42. In the present embodiment, the cylindrical portion 61 is a part of the inner panel 42 and is integrated with the inner panel 42. However, it is also possible to form the cylindrical portion 61 separately from the inner panel 42 and attach it to the inner panel 42 later. In the present embodiment, the cylindrical portion 61 is formed in a rectangular tube shape. However, the shape of the cylindrical part 61 is not specifically limited, For example, you may form in other shapes, such as a cylindrical shape, a long cylindrical shape, and a triangular cylinder shape. The cylindrical portion 61 preferably extends substantially horizontally in a side view, but may be slightly inclined forward or backward. As shown in FIG. 4, in the present embodiment, the cylindrical portion 61 extends substantially horizontally.

  As shown in FIGS. 2 and 4, the radiator 40 is disposed on the rear side of the main opening 72 of the inner panel 42. The radiator 40 is supplied with traveling wind passing through the main opening 72.

  As shown in FIGS. 4 and 5, a bracket 43 is supported on the right side portion of the radiator 40. A stay 44 that supports the horn 70 is attached to the bracket 43. Thus, the horn 70 is supported by the radiator 40 via the stay 44 and the bracket 43. The horn 70 is disposed behind the cylindrical portion 61 of the inner panel 42. Therefore, the horn 70 is disposed at a position spaced rearward from the horn opening 60 of the inner panel 42. Further, the horn 70 is arranged so as to face substantially forward through the horn opening 60 so as to emit a warning sound forward through the horn opening 60. That is, the horn 70 is disposed substantially forward. Further, the horn 70 is arranged so as to face a direction substantially along the longitudinal direction of the cylindrical portion 61.

  In the present specification, the phrase “arranged so as to face substantially forward” is not only a case where it is disposed forward in a strict sense, but also a case where it can be regarded as disposed forward. included. That is, not only the case where the plane is formed parallel to the plane formed by the horizontal line and the vertical line, in other words, the plane orthogonal to the longitudinal direction of the vehicle body, but also the case where the plane is slightly inclined with respect to the plane is included. For example, when viewed from the front, the horn 70 is inclined so that the left and right ends and the upper and lower ends can be seen. In addition, for example, it is considered that even when the inclination angle with respect to the plane is within 30 degrees, it is arranged so as to face substantially forward.

  Next, the positions of the horn opening 60 and the horn 70 when viewed from the front will be described. As shown in FIG. 2, the horn opening 60 and the horn 70 are disposed on the right side of the main opening 72. However, a part of the horn 70 may be located inside the main opening 72. The horn opening 60 and the horn 70 are disposed on the right side of the radiator 40. Specifically, the horn opening 60 and the horn 70 are disposed between the right end of the radiator 40 and the outermost end 22 a of the right side cover 22.

  Further, the horn opening 60 and the horn 70 are arranged on the right side of the front fork 14. Specifically, the horn opening 60 is disposed between the right end 14 a of the front fork 14 and the outermost end 22 a of the right side cover 22. The left and right widths of the horn 70 are shorter than the distance between the right end 14a of the front fork 14 and the outermost end 22a of the right side cover 22, and the horn 70 has the right end 14a of the front fork 14 and the right side. The cover 22 is disposed between the outermost end 22a. In the present embodiment, the entire horn 70 is disposed on the right side of the right end 14a of the front fork 14, but only a part of the horn 70 is positioned on the right side of the right end 14a of the front fork 14. You can also

  As shown in FIG. 7, the horn 70 is disposed on the right side of the cylinder 30 b of the engine 30. Specifically, the horn 70 is disposed between the right end of the cylinder 30 b and the outermost end 22 a of the right side cover 22.

  As described above, according to the motorcycle 10 according to the present embodiment, when viewed from the front, at least a part of the horn 70 is at a position overlapping the inner panel 42 and to the right of the front fork 14 (that is, in the left-right direction) It is arranged outside). Therefore, according to the present embodiment, since the sound output from the horn 70 is transmitted directly to the front without being interfered with the front fork 14, the motorcycle 10 capable of sufficiently securing the volume of the horn 70 is realized. be able to. Moreover, it can suppress that the horn 70 becomes air resistance.

  In the motorcycle 10 according to this embodiment, the front wheel 12 has a narrower width than the front wheel of this type of conventional motorcycle. When the width of the front wheel is wide, the space between the left and right tubes of the front fork is widened, so even if the horn is placed inward in the left and right direction of the front fork, the interference between the sound of the horn and the front fork is not a problem. Must not. However, when the width of the front wheel 12 is small, the distance between the left and right tubes of the front fork 14 is narrowed. Therefore, unless special measures are applied as in this embodiment, the sound of the horn 70 and the front fork 14 It becomes easy to interfere. Thus, the effect of the present embodiment becomes more prominent as the width of the front wheel 12 is smaller.

  On the other hand, in the motorcycle 10 according to this embodiment, since the lateral width of the front wheel 12 is thin as described above, the left and right width of the front fork 14 is shortened, and compared with the outer portion of the front fork 14 of the inner panel 41 in a front view. Large area is secured. Therefore, when viewed from the front, the horn 70 can be easily disposed outside the front fork 14 in the left-right direction. The inventor of the present application pays attention to this point and arranges the horn 70 outside the front fork 14 in the left-right direction.

  According to the motorcycle 10 according to the present embodiment, the inner panel 42 (see FIG. 3) has a main opening 72 extending left and right across the center in the left-right direction, and at least a part of the left-right direction outside the main opening 72. A horn opening 60 located on the opposite side is formed. The horn 70 is disposed substantially forward behind the horn opening 60 of the inner panel 42 (see FIGS. 4 and 5). Therefore, the horn 70 does not disturb the flow of traveling wind flowing from the front of the vehicle toward the rear through the main opening 72. In the present embodiment, the radiator 40 is disposed behind the main opening 72, but the flow of the traveling wind supplied to the radiator 40 is not likely to be disturbed by the horn 70. Therefore, a decrease in the cooling performance of the radiator 40 is suppressed. Further, since the horn 70 is arranged so as to face substantially forward, the warning sound from the horn 70 is smoothly output forward. Furthermore, since the horn 70 is located outward from the main opening 72, it is possible to suppress the warning sound from the horn 70 from interfering with the front wheel 12. Therefore, even if the horn 70 itself is not enlarged, a warning sound having a sufficient volume can be reached by a person in front of the vehicle. Therefore, the horn 70 can be reduced in size, weight, or cost can be reduced.

  According to the present embodiment, the horn 70 is disposed so as to be separated rearward from the horn opening 60 of the inner panel 42 (see FIG. 5). Therefore, even when the mud splashed from the ground is scattered in the vicinity of the horn opening 60, the risk of the mud adhering to the horn 70 is reduced. Therefore, the possibility that the warning sound from the horn 70 is weakened by mud adhering to the horn 70 is reduced.

  Furthermore, according to this embodiment, the cylindrical part 61 extended back is provided around the opening 60 for horns of the inner panel 42 (refer FIG. 6). Thereby, it can further suppress that the mud splashed from the ground adheres to the horn 70. Further, the tubular portion 61 suppresses the divergence of the warning sound output from the horn 70. That is, the cylindrical portion 61 serves as a so-called megaphone, and can effectively emit a warning sound from the horn 70 toward the front. Furthermore, the strength of the inner panel 42 is improved by the cylindrical portion 61 serving as a so-called reinforcing rib. Accordingly, the inner panel 42 is formed with a plurality of openings (in the present embodiment, the main opening 72, the ventilation openings 50L and 50R, the ventilation openings 52L and 52R, and the horn opening 60). The strength of can be kept high enough.

  According to the present embodiment, the horn opening 60 is formed above an intermediate position in the vertical direction of the inner panel 42 in a front view (see FIG. 3). Further, the upper end of the horn 70 is located above the upper end of the radiator 40 (see FIG. 4). Thus, since the positions of the horn opening 60 and the horn 70 are high, the mud splashed from the ground is less likely to adhere to the horn 70. Moreover, since the positions of the horn opening 60 and the horn 70 are high, the warning sound from the horn 70 can be transmitted more effectively to a person or the like in front of the vehicle.

  Further, according to the present embodiment, the horn opening 60 is formed on the side of the main opening 72 (see FIG. 3). Therefore, it is possible to secure a sufficient space for forming other openings (ventilation openings 50L, 50R, 52L, 52R in the present embodiment) in the lower portion of the main opening 72 in the inner panel 42.

  According to the present embodiment, the ventilation openings 50L, 50R, 52L, and 52R are formed below the main opening 72 and the horn opening 60 in the inner panel 42. Therefore, traveling wind can be introduced from the front of the inner panel 42 to the rear through the ventilation openings 50L, 50R, 52L, 52R. Therefore, the inner panel 42 effectively cools the vehicle parts by the traveling wind taken from the ventilation openings 50L, 50R, 52L, and 52R while preventing mud etc. from adhering to the vehicle parts such as the engine 30 to some extent. It becomes possible.

  As described above, according to the present embodiment, the horn opening 60 and the horn 70 are arranged on the right side of the front fork 14 in a front view (see FIG. 2). Therefore, the warning sound output from the horn 70 is not hindered by the front fork 14. Therefore, even if the horn 70 is not increased in size, a sufficiently large warning sound can reach a person in front of the vehicle. According to the present embodiment, since it is not necessary to provide the horn 70 in front of the front fork 14, the width of the front fork 14 (in other words, the fork pitch) can be reduced. As a result, the width of the front wheel 12 can be shortened. Further, the turnable angle of the handle 16 can be increased, and the so-called small turn motorcycle 10 can be realized.

  According to the present embodiment, the horn 70 is supported by the radiator 40 via the bracket 43 and the stay 44 (see FIG. 5). That is, the horn 70 is indirectly supported by the radiator 40. Thus, by supporting the horn 70 with the radiator 40, it is not necessary to provide a member for supporting the horn 70 in the vehicle body frame 24. Moreover, it becomes easy to arrange the horn 70 near the inner panel 42. Further, since the radiator 40 is a relatively heavy vehicle part, it is a vehicle part that is hardly affected by vibration. Therefore, the horn 70 can be firmly supported by supporting the horn 70 on the radiator 40. Further, the possibility that the warning sound of the horn 70 is attenuated by vibration is reduced. In the present embodiment, the horn 70 is indirectly supported by the radiator 40, but the horn 70 can also be directly supported by the radiator 40.

  According to this embodiment, when viewed from the front, the horn 70 is disposed on the right side of the intermediate position in the left-right direction of the vehicle, and the exhaust pipe 33 is disposed on the left side (see FIG. 2). Thus, by arranging the horn 70 on the side opposite to the side where the exhaust pipe 33 is provided, interference between the horn 70 and the exhaust pipe 33 can be easily avoided, and the position of the exhaust pipe 33 is restricted. The installation position of the horn 70 can be selected relatively freely without any problem.

  The engine 30 according to the present embodiment is a single cylinder engine. Therefore, the width of the engine 30 is narrower than that of a parallel multi-cylinder engine. Further, the lateral width of the radiator 40 may be narrow. Therefore, it becomes easy to arrange the horn opening 60 and the horn 70 on the side of the main opening 72.

<Embodiment 2>
As shown in FIG. 8, in the second embodiment, the horn opening 60 formed on the side of the main opening 72 is eliminated in the first embodiment, and the ventilation opening 52R is used as the horn opening. That is, in the second embodiment, the ventilation opening 52R in the first embodiment becomes the horn opening 60.

  In this embodiment, a bracket (not shown) is supported on the cylinder 30b of the engine 30, and the stay 44 of the horn 70 is attached to the bracket. In the present embodiment, the horn 70 is disposed substantially forward behind the horn opening (= the ventilation opening 52R).

  Other parts are the same as those of the first embodiment. Parts similar to those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted. Also in the present embodiment, at least a part of the horn 70 is disposed at a position overlapping the inner panel 42 in the front view and outside the front fork 14 in the left-right direction.

<Embodiment 3>
As shown in FIG. 9, the third embodiment is such that, in the first embodiment, the engine 30 is an air-cooled engine and the radiator 40 is omitted. Also in the present embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. Also in the present embodiment, the horn 70 is disposed on the right side of the cylinder 30b of the engine 30 in a front view (see FIG. 7). Further, the horn 70 is disposed at a position overlapping the inner panel 42 in the front view and outside the front fork 14 in the left-right direction.

  In the present embodiment, the traveling wind that has passed through the main opening 72 of the inner panel 42 is supplied to the cylinder 30 b of the engine 30. Here, the horn opening 60 and the horn 70 are formed on the side of the main opening 72, and the horn opening 60 and the horn 70 are arranged on the right side of the cylinder 30 b of the engine 30. Therefore, the flow of the traveling wind supplied to the cylinder 30b is not disturbed by the horn 70. Therefore, also in this embodiment, there is no possibility that the cooling performance of the engine 30 is hindered by the horn 70.

<Modification>
In each of the above embodiments, the cylindrical portion 61 is provided on the rear side of the horn opening 60 of the inner panel 42. However, as shown in FIG. 10, the cylindrical portion 61 can be omitted. Even if it is such a form, it can suppress that the mud splashed up from the ground adheres to the horn 70 by arrange | positioning the horn 70 in the position spaced apart back from the opening 60 for horns. When there is little risk of mud adhesion (for example, when the position of the horn opening 60 is high), the horn 70 is not provided at a position spaced rearward from the horn opening 60 but is provided in the horn opening 60. Also good.

  In each of the embodiments described above, the horn opening 60 and the horn 70 are provided on the right side in a front view. However, the horn opening 60 and the horn 70 may be provided on the left side when viewed from the front. Also in this case, the horn 70 is disposed at a position overlapping the inner panel 42 and on the left side of the front fork 14 (that is, outward in the left-right direction). Moreover, as shown in FIG. 11, the horn opening 60 and the horn 70 may be provided on both the right side and the left side in a front view. In this case, the left and right horns 70 are arranged at positions overlapping the inner panel 42 and outside the front fork 14 in the left-right direction.

  The positional relationship between the horn opening 60 and the main opening 72 is not limited to those in the above embodiments. When viewed from the front, the horn opening 60 and the main opening 72 may be formed at positions shifted vertically. The horn opening 60 may not be located entirely outside the main opening 72, and only a part of the horn opening 60 may be located outside the main opening 72 in the left-right direction. .

  A part of the horn 70 may overlap with the front fork 14 when viewed from the front. Further, when viewed from the front, the horn opening 60 and the front fork may partially overlap.

  A part of the horn 70 may overlap the horn opening 60 when viewed from the front. The entire horn 70 may be disposed inside the horn opening 60.

  In the embodiment, the horn opening 60 is formed by a single opening. However, the shape and the like of the horn opening 60 are not limited at all. The horn opening 60 only needs to be able to pass the sound output from the horn 70 forward, and various other embodiments are conceivable. For example, as shown to Fig.12 (a), the opening for horns may be comprised by the some louver opening 60b extended in a horizontal direction. Moreover, as shown in FIG.12 (b), the opening for horns may be comprised by the some louver opening 60c extended in an up-down direction. Moreover, as shown in FIG.12 (c), the opening for horns may be comprised by several small holes 60d like what is called a punching hole.

  Further, the main opening 72 is not limited to that of the above embodiment, and various modifications are possible. For example, the main opening 72 can be formed by a louver opening or a punching hole. Further, instead of the main opening 72 through which the traveling wind passes, it is also possible to provide a dummy opening through which the traveling wind does not pass.

<< Definition of terms etc. in this specification >>
In the present specification, the “opening of the inner panel” includes a hole formed inside the inner panel (that is, an opening that covers the entire periphery) and a bent portion formed on the periphery of the inner panel (that is, the opening).
