Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a vibration isolation structure for a fairing of a motorcycle.

(Prior Art) In order to reduce running resistance and protect passengers from the effects of wind, a windshield device called a fairing is used that covers the front of the steering wheel and extends rearward through the bottom of the steering wheel. The attached one is known, for example, from Japanese Utility Model Publication No. 52-22041.

(Problems to be solved by the invention) When such a fairing is attached, the center of gravity of the fairing often overhangs the mounting position of the fairing due to the structure of the motorcycle, and the space mass of the fairing is large, causing engine vibration. The current situation is that there are no effective measures to suppress vibrations.

The present invention has been devised to eliminate the above-mentioned disadvantages, and an object of the present invention is to provide a vibration-isolating structure for a fairing of a motorcycle that can suppress vibration of the fairing.

(Means for solving the problem) In order to achieve the above-mentioned object, the present invention has the following features:
Mount rubbers 30 are placed on the left and right locations of the center of the vehicle width on the lower surface of the intermediate portion 16b of the lower fairing 16.
It is characterized in that a steel plate bracket 20 is installed vertically between the two, and a turn signal 25 and other electrical components are attached to each of the brackets 20.

(Function) Vibration of the fairing 16 is suppressed by using the weight of the bracket 20 and electrical components. Furthermore, a bracket 2 suspends the running wind from the fairing 16.
The bracket 20 and the electrical components are caused to collide with each other, and in addition to the weight of the bracket 20 and the electrical components, it acts as a weight mass, particularly when driving at high speeds, to more effectively suppress vibration.

(Embodiment) Next, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

FIGS. 1 and 2 show external views of a motorcycle. The motorcycle 1 has an upper fork pipe 6 of a front fork 5 pivotally connected to a front head tube 3 of a body frame 2 via a bridge 4. A front wheel 7 is supported at the lower end, a handle 8 is attached on the bridge 4, a fuel tank 9 is attached on the frame behind this, a rear cowl 10 is attached to the rear of the frame, and a seat 11 is attached on this. is attached. An engine 12 is mounted under the fuel tank 9, a rear fork extends from the rear of the frame 2, and supports a rear wheel 13, and a rear action unit 14 is interposed between the rear fork and the upper rear part of the frame. ing.

The front upper part of the above motorcycle 1, that is, the front wheel 7
A windshield device 15 forming a fairing is provided to cover the lower part of the handlebar 8 from above, and the windshield device 15 includes a streamlined fairing main body 16 that acts as a windshield and guides the wind to reduce running resistance, and an upper front surface of the main body 16. Wind screen 17 installed at an angle
It consists of The main body 16 is located downward from the front of the handle,
Furthermore, extending from both sides of the fuel tank 9 to the left and right rear of the engine 12, a headlight 18 is provided at the front of the main body 16, and rear view mirrors 19 are provided at the upper left and right sides of the front portion 16a.

Brackets 20 are hung down from the left and right sides of the lower surface of the front part 16a to the middle part 16b of the fairing main body 16.

The bracket 20 is as shown in FIGS. 4 and 5, and has an inverted L-shape on the side, and includes an upper piece 20a, a side piece 20b bent and suspended from one surface of the upper piece, and an upper piece 20.
It has a rear piece 20c that hangs obliquely backward and downward from the rear end of a, and is made of a press-formed product made of a steel plate material, and has a symmetrical shape on the left and right sides. The upper piece 20a is provided with mounting holes 21, 21 spaced apart from each other in the front and back, the side piece 20b is provided with a stay 22 extending outwardly in the middle part, and the rear piece 20c is provided with a stay 22 extending outward.
A nut 23 is fixedly attached to the rear piece 20c, and the rear piece 20c is tapered downward, and a locking piece 20d bent forward is integrally formed at the lower end. A wire harness passage hole 24 is formed in the vicinity of the stay 22 mounting base of the side piece 20b.

In the above, the turn signal 25 is attached to the mounting hole 22a of the bracket 20 via the stay 22, and the stay 27 extending upward is fixed to the rear end of the horn 26 via the nut 23 of the rear piece 20c. A hole or the like is provided in the middle part of the stay 27 to lock the rear piece locking piece 20d to prevent rotation, and these wire harnesses (not shown) are routed through the through hole 24. The bracket 20 is suspended and fixed to the lower surface of the intermediate portion 16b of the fairing body 18 via bolts 29, 29.

Specifically, a cylindrical mount rubber 30 with an H-shaped cross section is press-fitted into the mounting holes 21, 21 of the upper piece 20a using its annular groove 30a, and a flanged collar 31 is fitted into the inner diameter of the rubber 30. Bolts 29, 29 are passed through from below the upper piece 20a and screwed into nuts 32 provided on the fairing side, thereby connecting the bracket 20 to the fairing 16 via the mount rubber 30. The mount rubber 30 substantially increases the capacity and provides vibration buffering and damping effects.

The bracket 20 on which the turn signals 25, horn 26, etc. are mounted and supported is located at the middle part 16 of the fairing.
It shall be installed hanging to the left and right of the center of the vehicle width in b.

In the example shown above, the turn signals and the horn are used as electrical components, but it is possible to attach other components.

The present embodiment is constructed as described above, and steel plate brackets 20 are provided at the left and right locations of the center of the vehicle width on the lower surface of the fairing intermediate portion 16b below the handlebar 8.
Since the turn signal 25 and the horn 26 are suspended, even if engine vibration is transmitted to the overhanging fairing, the vibration of the fairing 16 is suppressed by using the weight of the electrical components such as the bracket 20 and the turn signal 25. can do.

Furthermore, the wind flowing downward from the front surface of the fairing 16 hits electrical components such as the bracket 20 and turn signals 25 on the lower surface of the intermediate portion 16b of the fairing 16, so that the airflow that flows downward from the front surface of the fairing 16 hits the electrical components such as the bracket 20 and turn signals 25. This is added to the weight of the electrical components and acts as a weight mass on the fairing 16, making it possible to suppress vibrations of the fairing 16 more effectively.

Also, focus on the turn signal 2 on the bracket 20.
Since electrical components such as 5 and horn 26 are attached, separate brackets are not required as in the conventional case, the number of components can be reduced, and installation workability can be improved.

Furthermore, since the electrical components are mounted via the mount rubber 30, it is advantageous in terms of vibration isolation of the electrical components.

(Effect of the invention) As is clear from the above explanation, according to the invention,
Vibration of the fairing can be suppressed by using the weight of the bracket and electrical components.
