Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motorcycle having a pair of brake devices disposed on the left and right of front wheels, and connecting the operating parts of the pair of brake devices by connecting hoses extending above the front wheels. In particular, the present invention relates to a motorcycle having an improved structure in which a connecting hose is held by a fender covering an upper portion of a front wheel.

[0002]

2. Description of the Related Art A conventional motorcycle shown in FIGS. 3 and 4 includes a front wheel 1 supported by a pair of left and right front forks 9, and a fender 20 covering the upper portion of the front wheel 1. A pair of brake devices 3a and 3b having brake calipers (actuating parts) 4a and 4b are arranged on the left and right of the front wheel 1. The brake calipers 4a and 4b of the pair of brake devices 3a and 3b are connected by a connecting hose 6 that extends above the front wheel 1.

Of the pair of brake devices 3a and 3b, the brake caliper 4b of the right brake device 3a.
Further, one side of the main hose 8 extending upward is connected to the. As shown in FIG. 3, the other side of the main hose 8 is connected to the master cylinder 16. The hydraulic pressure generated in the master cylinder 16 by the operation of the brake lever 18 is transmitted to the brake caliper 4a of the right brake device 3a by the main hose 8 and the brake pressure of the left brake device 3b is transmitted by the connecting hose 6. It is also transmitted to the caliper 4b.

As shown in FIG. 4, a plurality of clamps 14 for holding the connection hose 6 are attached to the front side of the fender 20 at a position corresponding to the connection hose 6 (a rear portion of the fender 20). And the connection hose 6 is
It is held on the front side of the fender 20 by a plurality of clamps 14. Further, as shown in FIGS. 3 and 5, a radiator 10 is disposed behind the fender 20, and the air (traveling wind) flowing near the front side of the fender 20 hits the radiator 10 to cool the radiator 10. (See Figure 5).

[0005]

However, such a conventional motorcycle has the following problems. That is, as shown in FIG. 5, the air flow (running wind) on the front side of the fender 20 is disturbed by the connecting hose 6 held on the front side of the fender 20, so that air resistance and wind noise on the front side of the fender 20 are large. turn into. Moreover, since the connecting hose 6 is held by the plurality of clamps 14, the number of parts and the number of assembling steps increase.

The present invention has been made in consideration of such a point, and can prevent the air flow near the front side of the fender from being disturbed by the connecting hose, and
An object of the present invention is to provide a motorcycle in which parts for holding a connecting hose can be omitted.

[0007]

The means according to the present invention comprises a front wheel, a fender for covering the upper part of the front wheel, a pair of braking devices arranged on the left and right of the front wheel and having an operating portion, and above the front wheel. A motorcycle having a connecting hose for connecting between the operating portions of the pair of brake devices, the fender is formed with a groove portion across the front side thereof, and the connecting hose is held in the groove portion. It is characterized by having done.

According to this means, since the connecting hose is held in the groove portion crossing the front side of the fender, it is possible to prevent the air flow (running wind) near the front side of the fender from being disturbed by the connecting hose. . Further, it is not necessary to provide a member for holding the connecting hose on the front side of the fender.

[0009]

Next, an embodiment of the present invention will be described with reference to the drawings. In addition, in the embodiment of the present invention shown in FIGS. 1 and 2, the same components as those of the conventional example shown in FIGS. The same components will be described with reference to FIG. 3 as appropriate.

1 and 2 are views showing an embodiment of the present invention. In FIG. 1, the motorcycle includes a front wheel 1 supported by a pair of front forks 9 and a fender 2 that covers an upper portion of the front wheel 1 and is fixed to lower portions 11 of the pair of left and right front forks 9. I have it. A pair of brake devices 3 are provided on the left and right of the front wheel 1.
a and 3b are provided. Each braking device 3a, 3b
Is a brake disc 5 attached to the front wheel 1.
a, 5b and brake calipers (operating parts) 4a, 4b which are mounted on the lower portion 11 of the front fork 9 while sandwiching the brake discs 5a, 5b.
And Then, the pair of brake devices 3a, 3
The front wheel 1 is located between the brake calipers 4a, 4b of b.
Are connected by a connecting hose 6 extending over the upper part of the.

Of the pair of brake devices 3a, 3b, the brake caliper 4b of the right brake device 3a.
Further, one side of the main hose 8 extending upward is connected to the. The main hose 8 is held by a clamp 12 attached to the right side of the fender 2, and the other side is connected to a master cylinder 16 (see FIG. 3). Then, the brake lever 18 (see FIG. 3)
The hydraulic pressure generated in the master cylinder 16 by the operation of
The main hose 8 transmits the brake caliper 4a of the right brake device 3a, and the connection hose 6 transmits the brake caliper 4b of the left brake device 3b.

Next, as shown in FIGS. 1 and 2, at a position corresponding to the connecting hose 6 of the fender 2 (a rear portion of the fender 2), a groove portion 7 crossing the front side thereof is formed. The connecting hose 6 is the fender 2
It is held in the groove portion 7 formed in. Further, as shown in FIG. 2, a radiator 10 is arranged behind the fender 2 (see FIG. 3), and the air (traveling wind) flowing near the front side of the fender 2 hits the radiator 10 to cool the radiator 10. It is like this.

Next, the operation of this embodiment having such a configuration will be described. According to this embodiment, since the connecting hose 6 is held in the groove portion 7 that crosses the front side of the fender 2, it is possible to prevent the air flow near the front side of the fender 2 from being disturbed by the connecting hose 6. Therefore, it is possible to reduce air resistance and wind noise on the front side of the fender 2 of the motorcycle, smooth the air flow hitting the radiator 10, and improve the cooling efficiency of the radiator 10. Further, it is not necessary to mount a component for holding the connecting hose 6 on the front side of the fender 2. Therefore, it is possible to reduce the number of parts of the motorcycle and the number of assembling steps.

As shown in FIG. 1, even if the lower portion 11 of the front fork 9 strokes up and down together with the front wheel 1, the fender 2 and the brake caliper 4 are also moved.
Since both a and 4b are attached to the lower portion 11 of the front fork 9, the brake caliper 4a,
The connecting hose 6 that connects the 4b to each other also interlocks with the fender 2. Therefore, by appropriately setting the length of the connecting hose 6 and the like, the connecting hose 6 can be removed from the inside of the groove 7 even if the cross-sectional shape of the groove 7 is not formed to prevent the connecting hose 6 from falling off. There is no danger of

[0015]

According to the first aspect of the present invention, since the connecting hose is held in the groove that crosses the front side of the fender, the air flow (running wind) near the front side of the fender is disturbed by the connecting hose. Can be prevented. Therefore, air resistance and wind noise on the front side of the fender of the motorcycle can be reduced. Further, it is not necessary to provide a member for holding the connecting hose on the front side of the fender. Therefore, it is possible to reduce the number of parts of the motorcycle and the number of assembling steps.
