Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fairing device for a motorcycle including a windshield that relieves wind pressure mainly applied to a driver's upper body.
[0002]
[Prior art]
Supersport type motorcycles that have a shape close to that of a road racer are equipped with a fairing that reduces the air resistance during high-speed driving. This type of fairing consists of an upper cowl, a middle cowl and an under cowl. The upper cowl is positioned in front of the upper portion of the front fork, and has a transparent windshield that relieves wind pressure mainly applied to the upper body of the driver. The middle cowl and the under cowl cover a range from the side of the engine to the bottom, and mainly protect the driver's legs from wind pressure.
[0003]
By the way, the upper cowl covers and conceals the lamp body and meter unit of the headlamp disposed in front of the upper portion of the front fork, and a window support portion is formed at the upper end of the upper cowl. The window support portion has a cutout portion that is tapered downward while being inclined downward as it advances forward, and a windshield is screwed to the peripheral portion of the cutout portion.
[0004]
The windshield is smoothly curved downward as it goes forward, above the lamp body and meter unit, and rectifies so that the air flow from the front is smooth while the motorcycle is running. Yes. For this reason, when the driver travels with his / her upper body lying in the windshield so that he / she lies inside the windshield, the driver secures a forward view through the windshield.
[0005]
Further, this type of upper cowl has a front surface connected to the windshield, and the lens of the headlamp is exposed on the front surface of the upper cowl. In this case, as seen in, for example, “JP-A-11-59529”, in a motorcycle in which a pair of headlamps are arranged in front of the front fork and spaced apart from each other in the vehicle width direction, the lens of the headlamp is Exposed side by side on the front surface of the upper cowl, the front end of the notch portion of the window support portion is positioned above these lenses.
[0006]
Therefore, when the motorcycle is viewed from the front, the front end of the windshield is located higher than the headlamp, and the front of the upper cowl connecting the front end of the windshield and the lens of the headlamp is formed just between the lamp body. Located in front of the space.
[0007]
[Problems to be solved by the invention]
On the other hand, a super sports type motorcycle may be used as a road racer by removing a safety part such as a flasher lamp. In such a usage pattern, the driver is often forced to face down, and inevitably increases the chance of looking forward through the windshield.
[0008]
However, in a motorcycle having left and right headlamps as seen in the above-mentioned publication, the front end of the windshield is located higher than the pair of headlamps, so that the upper body is particularly turned down so as to be buried inside the windshield. When driving in a different posture, the upper part of the front surface of the upper cowl may enter the driver's field of view.
[0009]
For this reason, there is a risk that it may be difficult to check the road surface condition immediately before the front wheel and the distance between the front wheel and the preceding vehicle when traveling in a face-down position, and there is still room for improvement in this regard. Yes.
[0010]
The present invention has been made based on such circumstances, and when looking through the windshield while ensuring workability when fitting the fitting pin of the upper cowl to the support portion of the headlamp assembly. The purpose of the present invention is to provide a fairing device for a motorcycle that can easily expand the driver's forward view downward .
[0011]
[Means for Solving the Problems]
In order to achieve the above object, a motorcycle fairing device according to one aspect of the present invention is provided.
A headlamp assembly having left and right lamp bodies spaced apart in the vehicle width direction in front of the front fork and left and right lenses connected to the front ends of the lamp bodies ;
Are anda cowl covering the upper portion of the lamp body and the front fork of the headlamp assembly from the front.
The upper cowl has a window support portion above the headlamp assembly, and the window support portion has a notch portion that is tapered downward while being inclined downward as it advances forward. A transparent windshield that covers the notch is attached to the part.
The headlamp assembly has a connecting portion straddling between the lamp bodies below the upper surface of the lamp body, and a support portion protruding forward from the connecting portion,
The upper cowl has a front surface from which the lens of the headlamp assembly is exposed, and a fitting pin that protrudes rearward from a central portion of the front surface that is located between the lenses. The front surface of the upper cowl is supported by the support portion by being fitted to the support portion of the lamp assembly.
When the upper cowl is viewed from the front, the window support portion of the upper cowl is inserted between the left and right lamp bodies at the front end of the tapered cutout, and the windshield is connected to the front end of the cutout portion. The front end of the extended portion is positioned in front of the fitting portion between the support portion of the headlamp assembly and the fitting pin. It is set to.
[0012]
According to such a configuration, while the motorcycle is running, the driver looks forward through the windshield of the upper cowl in a state where the driver lies down so that the upper body is buried inside the windshield.
At this time, the front end of the notch portion of the window support portion and the front end of the extension portion of the windshield are positioned in front of the fitting portion between the fitting pin of the upper cowl and the support portion of the headlamp assembly. Therefore, when the motorcycle is viewed from the front, the front end of the notch portion of the wind support portion and the extended portion of the windshield can be inserted between the lamp bodies, especially when the driver takes a lying posture. The driver can see the front through the windshield extension from between the lamp bodies.
[0013]
Therefore, the driver's field of view when looking forward through the windshield can be expanded downward, and the road surface condition immediately before the front fork and the trend of the preceding vehicle can be easily recognized.
In addition, when the fitting pin of the upper cowl is fitted to the support portion of the headlamp assembly, the alignment operation between the fitting pin and the support portion can be performed through the front end of the notch portion. Therefore, the operation | work which fits a fitting pin with a support part becomes easy.
