Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a motorcycle that can run stably even on slippery roads such as ice and snow roads.

[Conventional technology]

Conventionally, in order to ensure steering stability on slippery roads such as those mentioned above, snow tires have been used on the front wheels of bicycles, and metal chains or snow spike ties have been installed on the rear wheels. Measures are being taken to ensure that they are used.

[Problem to be solved by the invention]

Attaching and detaching the metal chains to the tires is troublesome, and especially when driving alternately on icy and snowy roads and normal roads, the above operations become extremely troublesome.

On the other hand, if snow spike ties A7 are used, 11152 work on the chain becomes unnecessary, but in recent years, the problem of dust generation due to the above spikes scraping the road surface has become serious, and the use of snow spike ties A7 has become much less effective. It is becoming restricted.

Furthermore, it has been revealed that safety cannot be ensured simply by using snow tires for the front wheels in tests of handling stability.

In view of these circumstances, it is an object of the present invention to provide a seven-wheel cycle that can sufficiently ensure safety on icy and snowy roads, etc., without producing dust and eliminating the need for troublesome work. purpose.

[Means to solve the problem]

In the present invention, a net-like anti-slip device made of an elastic member is removably attached to the circumferential surfaces of front and rear wheels.

Furthermore, it is more effective to fix the anti-slip fitting to the surface of the anti-slip tool.

[For production]

According to the above configuration r, the slip of the tires on the road surface is suppressed on both the front and rear of the vehicle body by the net 1-shaped 81 stoppers made of elastic members attached to the front and rear wheels.

Furthermore, if a non-slip metal fitting is fixed to the surface of the above-mentioned slip-on shell, the anti-slip effect is further enhanced by the anti-slip metal fitting.

(Example) The bicycle 10 shown in FIG. 1 is equipped with snow ties V (front wheel>11J5) and snow tires (rear wheel) 12 at the front and rear thereof, and each snow tire 11.12
A net-like anti-slip device 14 made of an elastic member such as rubber is removably attached to the circumferential surface of the device.

This anti-slip tool 14 is integrally vulcanized by a conventional press molding method, and has a large number of mesh spaces 141 as shown in FIG.

At the intersection of this net-like anti-slip tool 14, a spike metal fitting (an anti-slip metal fitting) 16 as shown in FIG.
is installed. This spike metal fitting 16 is made of carbon S1
The main body 17 (large-diameter head part 1

3 in order. The depth 1 E3 is fixed to the head part 171, and the shank part 172 is fixed to the head part 171.
is attached to the anti-slip tool 14 so as to pass through the anti-slip tool 14, so that the anti-slip tool 14 is held between the head portion 171 and the washer portion 173 from both sides.

An example of the mounting structure of this anti-slip tool 14 is shown in FIG.

In this figure, a non-slip device 14 is attached to the front snow tire 11.
It shows the state in which it has been prepared.

In the figure, a plurality of mounting fittings 20 are fixed to both edges of the anti-slip device 14 in the left-right direction (width direction of the tire).

Presumably, one end of each mounting fitting 20 is caulked to both left and right edges of the non-slip shell 1/l, and a hook portion 201 is formed at the other end. Then, hook the O-ring 22 made of an elastic material such as rubber onto the hook part 201 of the mounting bracket 20 on either the left or right side (), turn this O-ring 22 to the inside of the rim 111 of the snow tie 711, and attach the other side. By hooking the hook part 201 of the mounting bracket 20, the right mounting bracket 20 is connected with an O-ring 22, and the elastic force of this O-ring 22 prevents slipping.
is gathered around the circumference of snow tie r11, and phase ff1ff
It is now in first place.

As described above, according to the motorcycle 10 in which the front and rear wheels are equipped with the net-shaped anti-slip devices 14 made of elastic members, the front and rear anti-slip devices 14 reliably suppress the slipping of the tires on the icy and snowy road surface. This makes it possible to improve steering stability and braking performance on road surfaces that are prone to rolling. Further, by fixing a non-slip metal fitting such as the spike metal fitting 16 to the surface of the anti-slip tool 14, the anti-slip effect is enhanced. In addition, the net-shaped anti-slip device 14 made of such an elastic member is easier to attach and detach from the snow tire 11.12 compared to a conventional metal chain, and the anti-slip device 14 cannot be removed on a normal road surface. This can prevent the occurrence of powder particles from the road surface.

The table shown on the next page shows the motorcycle of the present invention, the conventional [-tacycle] using known snow tires on the front and rear wheels, and the known snow spike tie A7 on the front and rear wheels.
were used for pitching tests, braking tests,
We also present the results of a handling stability test.

Here, the same vehicle (Honda Super Cub 90cc) was used for each motorcycle, and the tire size was 2.25-17 for the front wheel and 2.50-17 for the rear wheel.
It is controlled by the things of In addition, as the snow tire, a conventionally known one having a pattern as shown in FIG. 5 is used, and as the snow spike tie 7, a
As shown in the figure, a snow tie V shown in FIG. 5 is used in which a spike fitting 28 is fixed to a mounting hole 26 provided in the snow tie V. As shown in FIG. 7, this spike fitting 28 includes a shank member 281 made of carbon steel or the like.
Jj and a chip member 282 made of cemented carbide,
The shank member 281 is fitted and fixed into the mounting hole 26.

In the climbing test, each motor was started at 1 J cycle on the 11th point of a slope with a slope of 8% consisting of a water basin, and it was examined whether the vehicle could climb smoothly at an acceleration of 1, and this was expressed as a good index. This is a measurement of +f after driving on a 30m slope.The higher the above index, the better the σ slope.

In the braking test, each motorcycle was run at 201/h, and the brake was applied only to the drive tie V side using the method specified in JI301034 (two-wheel self-width brake test method). This is a measurement of braking distance. Again, the higher the goodness index, the better the braking performance.

In the handling stability test, three test riders ran each motorcycle on snowy roads and watery roads, and the average value of the feeling test results was expressed as an index. Here, too, the higher the goodness index, the better the steering stability.

As can be seen from the test results, the motorcycle of the present invention has improved sigma stability, braking performance, and handling stability compared to a motorcycle that uses only snow tires on the instep or a motorcycle that uses snow spike tires. ↑J3 is very good in any of the points above.

<r<r>The present invention is not limited to the above-mentioned embodiments, but can be modified by taking the following embodiments as examples.

(1) In the present invention, irrespective of the specific structure of the anti-slip tool, the anti-slip shell may be one in which the rest is formed into a net shape using an elastic member such as rubber.

For example, a plurality of unit members formed in the shape of rings or small nets may be interconnected to form a net-like anti-slip device as a whole.

(2) As for the metal fittings attached to the anti-slip tool, it is only necessary to have one that enhances the anti-slip effect.In addition to the spike metal fittings 16 mentioned above, for example, as shown in FIG. The stopper 14 may be caulked.

(3) In the embodiment described above, snow tires are used for the front and rear wheels, but it is also possible to place pickled seashells on regular tires. However, the use of snow tires has the advantage of being able to prevent slipping to a certain extent even with the anti-slip shell removed.

(4) The mounting structure of the non-slip shell on the tire according to the present invention [,5] In the present invention, both the left and right edges of the anti-slip device are tightened with wire lobes, elastic rings, etc. as shown in FIG. It is not possible to make the anti-slip shell adhere tightly to the circumference of the tire.

〔Effect of the invention〕

As described above, the present invention has a net-shaped anti-slip device made of an elastic material that is removably attached to the circumferential surface of the front and rear wheels, making it easier to attach and remove the anti-slip device and reducing the generation of dust. This has the effect of improving safety on slippery roads such as icy and snowy roads by providing reliable anti-slip protection at the front and rear while preventing this from happening.

Furthermore, when a non-slip metal fitting is fixed to the surface of the non-slip shell, the anti-slip effect of the tire is further enhanced by the non-slip metal fitting, thereby increasing safety.
