Description

[Detailed Description of the Invention] The present invention relates to a fairing device provided to cover the upper front portion of a motorcycle body.

A fairing is attached to the front of a motorcycle for the purpose of windshielding and regulating air flow.

Conventionally, such fairings are often provided to partially cover the upper front portion of the vehicle body, and are not the best in terms of appearance, windshield, and air flow.

Therefore, it has been proposed to cover the front part of the car body, including the engine, but this method causes the heat generated by the engine and other heat-generating parts, as well as the engine noise, to get trapped inside the fairing, making it not the best in terms of engine cooling and noise control. .

Therefore, the applicant has proposed a fairing device that extends the fairing from the front of the vehicle to the rear, hangs down from above the engine to the rear, and provides a fairing over the entire surface while exposing the engine, etc., which is a heat generating part, to the outside. However, in this case, there is a risk of a gap occurring between the inner end of the middle part of the fairing and the fuel tank on the vehicle body side, especially if the fairing is integrally molded into the above shape from synthetic resin etc. There is a risk of errors and assembly errors, and it is difficult to completely eliminate the gap between the fuel tank and the vehicle body.Since the side of the fuel tank is curved, the inner end of the above part of the fairing should be It is difficult to mold the material so that it contacts accurately.

The existence of such a gap may cause hot air to blow up since the engine is disposed below the gap, and there is also a risk that noise may enter through this gap.

The present inventors devised this invention in order to solve the above-mentioned inconveniences. This will close the gap that occurs between the inner end of the above part of the fairing and the lower side of the fuel tank, etc., thereby providing heat insulation and sound insulation while covering all but the engine with the fairing. An object of the present invention is to provide a fairing device for a motorcycle, which has excellent properties and is capable of achieving the above while suppressing the precision in molding and assembling the fairing to a certain degree.

Next, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 show the external appearance of a motorcycle 1, in which the upper part of a front fork 5 supporting a front wheel 6 is pivotally connected to a head tube 3 provided at the front end of a frame 2 by a bridge 4 so as to be freely steerable. A handle 7 is attached on the top bridge.

A fuel tank 8 is mounted on the front part of the frame 2, an engine 9 is mounted on a down tube 2a that hangs down from the head tube 3 of the frame 2 and extends rearward, and an engine 9 is mounted on the rear of the fuel tank 8. A seat cowl 11 is attached to the left and right sides under the seat 10.

A rear fork 12 that supports a rear wheel 13 is pivotably extended from the rear lower part of the frame to the rear.
A ballast cushion unit 14 is interposed between the rear part and the vehicle body.

A fairing 15 is attached to the front part of the motorcycle 1 described above for the purpose of windshielding and rectifying air flow.

The fairing consists of a main body 16 and a windscreen 17 erected at an angle on the front part of the main body 16.

The main body 16 is connected to the handle 7 in front of the upper part of the front fork 5.
A shell-shaped front part 16a that has a streamlined shape at the front and surrounds the front, left and right, bottom and around the windscreen, and extends rearward from the left and right of this, the upper left and right of the front fork 5, and the left and right of the head tube 3. , includes intermediate portions 16b, 16b extending to the front left and right sides of the fuel tank 8,
a faces above the front fender 18 of the front wheel 6, and a lower surface 16c of the intermediate portion 16b faces above the engine 9 and surrounds the upper part.

In the figure, the engine 9 has multiple cylinders, and each cylinder 9a and cylinder head 9b are arranged on both sides, and each intermediate portion 16
b extends rearward so as to cover the cylinder head 9b.

A rear portion 16d of the intermediate portion 16b extends to the rear of the engine 9, and a rear piece 16e is provided at each rear portion 16d of the left and right intermediate portions 16b.
is installed hanging down, and the upper end of the rear piece 16e is connected to the rear part 16d.

The front surface 16f of the rear piece 16e is the left and right cylinders 9a of the engine 9.

It faces the rear surface of the cylinder head 9b and surrounds the rear of the left and right parts of the engine, thus leaving the front and sides of the engine open.

The bottom plate portion 16 of the intermediate portion 16b of the fairing body 16 as described above.
A gap S is provided between the inner end 16h of the fuel tank 8 and the lower ends 8b of the side plates 8a of the fuel tank 8, and the engine 9 is located directly below the gap S.

This gap S is extended from the front end of the fuel tank to the rear end of the fairing main body intermediate portion 16b, and this portion is closed with a cover plate 19.

The cover plate 19 is made of a member having some degree of flexibility, such as rubber, and in the embodiment shown in FIG. A mounting hole 16i was formed, and a projection 19a protruding from the lower surface of the cover plate 19 was engaged with the mounting hole 16i to determine the position in the width direction.

The cover plate 19 covers the gap S and connects the inner end 19b to the fuel tank 8.
butts against the outer surface of the lower end 8b, thus closing the gap S.

As a result, the gap S defined by the side surface of the fuel tank of the fairing body is closed, making it possible to block hot air from the engine toward the passenger side and engine noise.

6 and 7 show modified embodiments, and FIG. 6 shows the cover plate 1.
An upward protrusion 119a is provided at the inner end of the cover plate 119, and a groove 119b is formed on the upward protrusion 119a to engage the lower end 8b of the fuel tank 8. It is mounted and supported on the bottom plate portion 16g.

Figure 7 shows the outer part of the cover plate 219 and the bottom plate 16g of the middle part of the main body.
The inner end 219a of the inner end 219a extends to the middle part of the bottom of the tank 8, passing under the lower end Bb of the tank 8.

The cover plate may be mounted and supported as described above, and the structure for mounting and supporting the cover plate is arbitrary.

Although the illustrated embodiment has been described above, in addition to the space between the fuel tank and the inner end of the fairing body, the covering plate extends to the front gap, thereby creating a gap between the vehicle body side and the inner end of the fairing body. Close the gap.

In the drawing, 20 is a headlight provided at the front end of the fairing body 16, 21 is a rearview mirror provided on the left and right sides of the front part of the fairing body, and 22 is a turn signal attached to the left and right sides of the front or middle lower surface of the main body 16. - indicates.

As is clear from the above, according to the present invention, the engine is exposed, the fairing body is provided almost entirely, the gap between the body and the fuel tank is closed, hot air and noise are blocked,
It is possible to prevent this from entering the fairing.

In particular, we intentionally created a gap between the outer surface of the fuel tank and the outer surface of the fuel tank.
Since this is closed with a cover plate, manufacturing errors and assembly errors of the fairing are allowed, and a fairing with excellent functionality can be easily obtained and easily assembled.
It has many advantages such as being advantageous in terms of cost when putting the fairing into practical use.
