Prior art documents relating to this type of headlamp include JP-A-6-103801 and JP-B-7-97441.
[0003]
[Problems to be solved by the invention]
By the way, the strongest part of the front cowling receives the traveling wind, in other words, the center part of the front cowling in the vehicle width direction. Therefore, the highest supercharging effect can be obtained by providing an intake inlet at the center of the front cowling and the vicinity thereof. However, in the conventional motorcycle headlamp device, in the case of the two-lamp type, since the headlamp has to be located at the tip, an intake intake is provided outside the headlamp on a side part shifted from the center of the tip. It will open. Therefore, a strong wind pressure cannot be used effectively, and the space in the center cannot be effectively used, and as a result, there has been a problem that the supercharging effect cannot be improved.
[0004]
Further, in the conventional motorcycle, since the turn signal and the intake opening are separately configured, from the viewpoint of preventing interference between the turn signals and the like, a space between the mounting wall portion of each turn signal and the outer wall portion of the air duct of the intake opening is provided. A gap had to be formed. Therefore, either the turn signal or the intake opening must be configured to be small with the formation of the clearance to prevent the width from expanding or to prevent an increase in air resistance. Because of the problem for that reason, the intake intake must be made smaller. As a result, similarly to the above, there is a problem that the supercharging effect is reduced.
[0005]
SUMMARY OF THE INVENTION The present invention has been made in view of the above-described conventional problems, and has as its object to provide a motorcycle headlamp device capable of changing a mounting position of a headlamp to improve a supercharging effect .
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention includes a streamlined front cowling that covers a front portion of a motorcycle, and a headlamp provided on the front cowling.
At the center of the front cowling in the vehicle width direction, a plurality of lamps are vertically arranged and attached.A lower lamp of the plurality of lamps is attached to a front end of the streamlined front cowling, and a lower lamp is attached. It is also characterized by a small-diameter ramp, approaching the left and right sides of the lower ramp, and an air intake intake for the engine's air intake system located closer to the center of the tip of the front cowling in the vehicle width direction .
It is preferable that, of the plurality of lamps, the upper lamp be a lamp provided with a reflecting mirror and the lower lamp be a projector lamp.
[0008]
According to the present invention, a reflector-type lamp is arranged above the center of the front cowling, and a projector lamp which can be generally formed into a small-diameter structure is arranged below the center of the front cowling. Intake intake openings can be located at the center of the front front cowling that is strongly received and / or near the left and right sides thereof. In addition, a generally long projector lamp can be set at the lower part of the center, so that the front cowling can be bent to form a streamlined structure, or the projector can be used to secure space for steering wheels, measuring instruments, electrical components, etc. The lamp does not become an obstacle.
