Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a running wind intake device for a motorcycle. 2. Description of the Related Art Motorcycles have a streamlined cowling whose outer sides are curved rearward so as to cover the front of a vehicle body so as to reduce wind resistance during traveling. As shown in FIG. 5, a headlamp B is mounted on the cowling at the upper center of an upper cowl A, which is an upper part of the cowling, and air inlets C are provided at both outer portions of the headlamp B. There is a type used to receive air from a vehicle during traveling to supercharge the intake air of the engine (supercharging of traveling wind), or to introduce cooling air. As shown in FIG. 6, an upper cowl A
There is also a type in which a headlamp B is mounted at the upper center of the vehicle and an air inlet C is provided below the central headlamp B. [0004] However, the dynamic pressure of the wind received during traveling is highest at the center of the upper cowl A received directly in front, and becomes lower as it goes to the outside that is curved rearward. Therefore, in FIG. 5, the air intake C is located at a location close to the outside, and the intake efficiency is not good. On the other hand, the traveling dynamic pressure increases near the center in the vehicle width direction,
In the thing of FIG. 6, although the air inlet C is in the center of the upper cowl A and can take in the wind with high dynamic pressure,
The oblong flat shape reduces the intake area. The larger the air intake C, the higher the position of the headlamp B, and accordingly, the higher the position of meters D such as a speedometer mounted above the headlamp B,
The meters D protrude greatly inside the transparent screen E connected to the upper side of the upper cowl A, and the condition becomes worse. In addition, the height of the headlamp B is narrowed by the air intake C and the meters D, so that an ideal reflector shape cannot be obtained, and conversely, the air intake C becomes narrow vertically. [0005] In view of the above, the present invention allows the traveling wind to be taken in from a place with a high dynamic pressure near the center of the cowling, so that the traveling wind can be taken in efficiently and the position of the headlamp can be improved. It is an object of the invention to obtain a motorcycle wind intake device that is not too high and does not protrude upward. In order to achieve the above object, the present invention provides a motorcycle wind intake device.
The headlamp attached to the upper front center of the cowling which covers a front portion of the vehicle body, from the central portion to the front lens of the headlamp toward the right and left side edge to form a lateral groove which gradually becomes deeper, the side edges of the lateral grooves, forward The opening is connected to the central wall of the air inlet opening. [0007] Since a high dynamic pressure portion of the wind received during traveling at the center of the cowling is guided to the lateral groove of the front lens of the headlamp and flows to the air inlet, the efficiency of taking in the traveling wind can be increased. The headlamp can be mounted so that the mounting position on the cowling is less restricted and the meter position is not too high. FIG. 1 shows an embodiment of the present invention.
This will be described with reference to FIGS. Since the entire configuration of the motorcycle is applicable to the motorcycle shown in FIG. 5, illustration of the overall configuration of the motorcycle is omitted. In a motorcycle, a front lens 5 of a headlamp 4 is attached to a window hole 3 at a center of an upper front surface of a cowling 2 covering a front portion of a vehicle body 1. The front lens 5 of the headlamp 4 is formed with a lateral groove 6 that gradually becomes deeper from the center toward the left and right ends.
On the left and right sides of the headlamp 4 of the cowling 2, a wall 7
Then, the air inlet 8 is formed, and the wall 7 on the center side is formed in the lateral groove 6 formed in the front lens 5 of the headlamp 4.
To be linked to The air inlet 8 is an inlet tube 9 passing near the front steering 13 and is connected to the engine 1.
4 is connected to an air cleaner 10 for filtering the intake air. At the upper end of the cowling 2, a transparent screen 11 that is continuous with the cowling 2 is mounted, and above the headlamp 4, a meter 12 is mounted rearward. The traveling wind of high dynamic pressure received by the central portion of the cowling 2 passes through the lateral groove 6 of the front lens 5 of the headlamp 4 and is received by the air inlet 8. Then, the air enters the air cleaner 10 through the introduction tube 9, and supercharges the intake air of the engine. Thus, the traveling wind can be efficiently used for supercharging. Further, the headlamp 4 can be mounted at a high position while ensuring a sufficient size, and the
The mounting position of 2 can also be made not too high. A lateral groove 6 is provided in the front lens 5 of the headlamp 4, and the light distribution of the headlamp 4 can be adjusted by cutting the inner surface of the front lens 5. In addition, the orientation can be prevented from causing a problem even when the angle of the broken surface of the character line around the lateral groove 6 is set to R15 or more. As described above, since the present invention is constructed as described above, the traveling groove having a high dynamic pressure near the center is formed by the lateral groove formed in the front lens of the headlamp provided at the center of the front of the cowling. The wind can be received through the lateral grooves into the air inlets provided on the left and right sides of the headlamp,
The traveling wind can be received efficiently. Then, the mounting position does not increase while the size of the headlamp is sufficiently secured, and the mounting position of the meter mounted above the headlamp does not become too high. Further, the change of the light distribution due to the lateral groove formed in the front lens of the headlamp may be adjusted by cutting the inner surface of the front lens.
