Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a front cover device for a two-wheeled motor vehicle or a three-wheeled motor vehicle.

Conventionally, motorcycles and three-wheeled vehicles have been known that are equipped with a front cover that covers the leg shield from the front in front of the head pipe of the vehicle body, but in this case, a relatively large space is formed inside the front cover. It is desirable to be able to effectively utilize this space as a housing space for radiators and headlights.

SUMMARY OF THE INVENTION An object of the present invention is to provide a device that satisfies such demands, and provides a two-wheeled motor vehicle or a three-wheeled motor vehicle equipped with a front cover that covers a leg shield from the front in front of a head pipe of a vehicle body. is arranged in a backward-inclined manner from the lower part above the wheel to the upper part in front of the head pipe, an air guide path is formed in the lower space within the cover that connects to the air guide port at the lower front of the cover, and a stay is installed in the air guide path. The present invention is characterized in that a radiator is provided which is fixed to the head pipe through a bracket, a head light is attached to the stay, and a baffle plate is interposed between the head light and the radiator.

Next, the present invention will be explained with reference to the illustrated embodiments.

Referring to Figures 1 and 2, 1 is 1 each in front and rear.
It shows a vehicle body equipped with a pair of wheels 2, 2, and a swing type power unit 4 equipped with a rear upper seat 3 and a water-cooled engine for driving the rear wheels 2 below the vehicle body 1. A two-wheeled vehicle is constructed, and furthermore, a footrest plate 5 is provided at the lower middle of the vehicle body 1, and a head pipe 6 and a down tube 7 of the vehicle body 1 are attached to the front end of the footrest plate 5 as shown in FIG. A leg shield 8 is provided to cover the leg shield 8 from the back, and a front cover 9 is provided in front of the head pipe 6 to cover the leg shield 8 from the front.

Here, according to the present invention, an air guide path 11 is formed in the lower space inside the front cover 9, and the air guide path 11 is connected to the air guide port 10 at the lower front surface of the front cover 9.
According to this, the radiator 12 is installed in the radiator 12 by effectively utilizing the ram pressure by introducing the running air from the air guide port 10 at the lower front of the cover 9 near the branching point of the running air. The cooling performance is improved, and the stability of the vehicle body 1 is also improved by arranging the heavy radiator 12 in the lower space of the cover 9 close to the front wheels 1. In the drawings, reference numeral 11a indicates a duct constituting the air guide path 11.

As shown in the figure, the radiator 12 is formed into a low horizontally long shape with water tanks 12a, 12a on both the left and right sides, as shown in FIG. 4, so that it can be compactly stored in the lower space. It is bolted to a bracket 14 fixed to the head pipe 6 via a pair of left and right stays 13, 13 which are wide in the vertical direction and are fastened to the upper and lower frame pieces 12b, 12b, and is used to prevent vertical vibrations of the vehicle body 1. The support rigidity of the radiator 12 can be increased.

In the drawing, 12c indicates a fan case provided on the back side of the radiator 12, and a fan 12e driven by a motor 12d on the back side of the fan case 12c is attached to the fan case 12c.
An air outlet 15 formed on the lower side surface of the front cover 9 accommodates a fan 12e to provide forced ventilation to the radiator 12, and directs air from the fan 12e through a transparent window 13a formed in each stay 13. It was made to be discharged from the outside.

Furthermore, according to the present invention, the headlight 16 is disposed in the upper space within the front cover 9, and unlike the conventional arrangement in which the headlight 16 is disposed on the handle side, handling by the inertial mass of the headlight 16 is improved. Moreover, by arranging the headlight 16 in the space above the cover 9, the necessary illumination angle can be obtained and visibility can be ensured.

The headlight 16 may be installed in a fixed manner so as to face the irradiation window formed on the front surface of the cover 9, but as shown in the figure, it may be retractable and movable together with a light lid 17 provided on the front surface of the cover 9 that can be opened and closed. If it is a type, the appearance will be good. In the drawings, reference numeral 18 denotes a support frame that supports the headlight 16 in a manner that it can be raised and lowered, 19 is a link mechanism for raising and lowering the headlight 16, and 20 is a link for opening and closing the light lid 17.

In addition, in the illustrated one, the headlight 16 is mounted on the stays 13, 13 in the support frame 18, and the headlight 16 and the radiator 12 are assembled to the stays 13, 13 in advance to enable small assembly. It has been made possible to improve workability on the interlock assembly line. Furthermore, the support frame 18 is mounted on the stays 13, 13 via the buff-full plate 21,
Direct action of hot air from the radiator 12 onto the headlight 16 can be prevented.

In addition, in the illustrated example, the upper half 9a of the front cover 9, which covers the area where the headlight 16 is arranged, is pivoted to a bracket 22 at the upper end fixed to the head pipe 6, so that it can be opened and closed, thereby improving maintainability. In addition, the lower half 9b of the cover 9 has a duct 11a constituting the above-mentioned conduction path 11 inside.
Insert each bolt 23 implanted in the stays 13, 13 from above through the mounting hole 24 at the upper end with the bolts attached, and bolt to the side rail portion 8a of the leg shield 8 through the mounting hole 25 at the rear of the lower end. And so.

It should be noted that the present invention is of course applicable not only to the above-mentioned two-wheeled motor vehicle but also to a three-wheeled motor vehicle having two rear wheels 1.

In this way, according to the present invention, the front cover 9
is arranged to be inclined backward from the lower part above the wheel to the upper part in front of the head pipe 6, and an air guide path 11 is formed in the lower space in the cover 9 that connects to the air guide port 10 at the lower front of the cover 9. Since the radiator 1 fixed to the head pipe 6 via the stay 13 is arranged in the air passage 11, the radiator 12 can be installed by effectively utilizing the space inside the front cover 9, and the center of gravity can be lowered. Since the inertia mass of the steering wheel does not increase, the stability of the vehicle body is not compromised.Moreover, the headlight 16 is attached to the same stay 13 as the radiator 12, and the bump-full plate 21 is interposed between the two.
6 can be placed as high as possible on the vehicle body side, and has the effect of blocking the direct action of hot air from the radiator 12.
