Abstract

PURPOSE:To prevent car slip and dust pollution by fixing a stud pin on a tyre and fitting a pin main body to the outside of the stud pin in a freely slidable manner together with providing a solid expansible body between them so that the stud pin comes out of or goes inside the tyre tread surface in accordance with road conditions. CONSTITUTION:A large number of pins 3 are embedded in the tread 2 of a tyre 1. A base plate 5 made of titanium alloy or the like, which extends outward and abuts on a ply player 4 within a tyre 1 in its shape is provided in the base part of a pin 3. And a recessed part 6 is formed in the middle of said base plate 5 facing the ply layer 4, in order to obtain reliable sucker action. In addition, a stud pin 7 made of titanium alloy or the like is erectd in the middle part of the base plate 5 on the outer surface side of the tyre, so that a pin main body 8 made of titanium alloy or the like can be fitted in a freely slid manner. Further, a solid expansible body 10 made of urethane rubber or the like is fitted on the outside of the pin main body 8. With this contrivance, when a vehicle travels on a snow-covered road, cooling effect of snow shrinks the said expansible body 10, pushes down the pin main body 8, and makes the stud pin 7 to project.

Description

[Detailed Description of the Invention] Technical Classification/Field> The disclosed technology belongs to the technical field of the bin structure of a spiked tire for snow-protecting roads mounted on a vehicle.

<Explanation of the gist> The present invention is an anti-slip bottle used for the spike tie A7 when a vehicle runs on a frozen road surface in winter, and the tip is exposed on the outer surface of the tie A7 to prevent snow. FA'' in bottle 1 of spike tie A7 which presses the surface etc. to lower the freezing point and gives a spike effect.
In particular, a stud pin whose base end is supported by the tread of a tire passes through a bottle body whose tip is exposed on the outer surface of the tie 17 in a relatively rotatable manner, and the bottle body and the base of the stud bottle.
The stud pin is made to protrude freely from the mirror-like curved surface of the tip of the stud pin through the solid elastic body made of urethane rubber, and as a result, the stud pin can be relatively freely protruded from the mirror-like curved surface of the bottle body. This invention relates to a spike tie (7) bottle structure.

<Prior art> In general, in snowy regions, there is snow on the roads in winter, and melted snow freezes at night, so normal
Vehicles equipped with 'slip easily (difficult to drive).
In addition, because it is extremely dangerous, chains and spike ties 17 are attached to deal with this problem.

Particularly in snowy regions where it is necessary to constantly deal with snow on the road surface, vehicle running stability is good, and compared to chains, there are no unattached parts, making it safer and easier to attach and detach. So-called spike ties ψ are often used due to their advantages such as:

Therefore, the principle of a spike tire is that the tip of the bottle body, which is cast into the tire, is exposed to the outer periphery of the tire, and when the tip is pressed against the snow surface, etc. The system uses the drop in freezing point to melt ice and snow, which bites into the road surface and prevents slips.

<Problems with the conventional technology> Above all, in the conventional spike tie V bottle structure, the bottle always protrudes from the road surface, so as its popularity increases, ice melts and the problem occurs during the transition to the dry season. The problem was that the road surface was worn out and the bottle body was also severely worn out.

To deal with this, various mechanical structures have been devised in which the bottle body protrudes from the outer surface of the tire when necessary, such as when driving on icy and snowy roads, but these are not only complex in structure and impractical; There was also the drawback that it was difficult to manufacture and use FW.

Furthermore, when there is no snow on the road surface, there is a problem in that the tip of the bottle scrapes away the road surface concrete 1-, etc., and the dust generated from the road surface becomes a pollution problem around the road.

In addition, the running resistance increases by the amount that the bottle sweeps on the road surface by W1,
This also had the disadvantage of worsening fuel efficiency.

<Objective of the Invention> The object of the present invention is to solve the technical problem of the pin structure of spike tie A7 based on the above-mentioned prior art.
Not only does it maintain the inherently superior function of Spike Tie-2 against ice and snow, but it also prevents road surface damage and minimizes the wear of the bins (road layer in early spring when the snow melts and the road surface is exposed). The purpose of this invention is to provide an excellent spike tie A7 pin structure that is useful for automobile applications in the transportation industry by preventing dust pollution generated in the industry.

<Structure of the Invention> 1) In accordance with the present purpose, the structure of the present invention, the gist of which is the scope of the above-mentioned claims, is to solve the above-mentioned problem. As the temperature of the spiked tire becomes low and the running speed of the vehicle decreases, the stud bottle embedded in the 1-red of the spike tie A7 and the bottle body that is penetrated by the stud bottle so as to be movable relative to each other. In addition to the solid elastic body made of urethane rubber interposed in between, the centrifugal force that the bottle body receives is small, so the bottle body is able to move the stud bottle away from the mirror-like curved surface at its tip. The stud bottle protrudes from the outer circumference of the tire and causes a spike effect on the snow surface by lowering the freezing point.On the other hand, when driving on a normal road surface, the tire rolls and causes high temperatures due to frictional resistance, etc. However, contrary to the above, the bottle body expands as the solid elastic body made of urethane rubber expands, and in addition, the bottle body expands due to centrifugal force. When the stud pin is retracted 1 degree relative to the bottle body, the tip of the stud pin does not press against the road surface, and the mirror-like curved surface of the bottle body contacts the road surface. Technical measures have been taken to reduce the risk of damage to the road surface.

<Embodiment - Configuration> Next, an embodiment of the present invention will be explained based on the drawings (the explanation will be as follows).

As shown in FIG. 1, a large number of bottles 3, which constitute the gist of the present invention, are buried in ties 1 to 2 of ties 71.

The bottle 3 has a tie at its base.
It is provided with an umbrella-shaped pedestal 5 made of titanium alloy and having an outwardly projecting shape that comes into contact with the pedestal 5.

In the center part of the pedestal 5 on the anti-blithe layer 4 side, there is a four part 6.
is formed, and the C edge contacts the braai layer 4 to provide a reliable suction cup action and assist the integration.
J, the sea urchin is turning.

At the center of the outer surface of the pedestal 5, a stud bottle 7 made of titanium alloy is erected and integrated by appropriate means, and a bottle body 8 made of titanium alloy is attached to the stud bottle 7. It is slidably mounted.

A large diameter portion 8' is formed at the tip of the stud bottle 7, so that the bottle body 8 can be securely stopped.

The bottle body 8 is formed into a curved hemispherical shape with a mirror-like surface 9 at the outer end, and has a total length that allows it to be smoothly exposed from the outer surface of the tire 1, and has a set length from the stand bottle 7. one! The lower side of the tower is shortened, and the stud bottle 7 is relatively moved relative to the bottle body 8.
It is made possible to stand out.

- Between the pedestal 5 as the base of the stud bottle 7 and the tip of the bottle body 8, a solid elastic body 10 made of urethane rubber is placed around the outer periphery of the bottle body 8 into which the stud bottle 7 is inserted. The upper and lower ends are fitted into the bottle main body 8 and the pedestal 5 in a screwed state.

Therefore, the outer periphery of the elastic body 10 is formed into a wave-like shape, so that it can be easily inserted into the tread 2, and is easily expanded and contracted.

<Embodiment - Effects> When the vehicle has J3 with the above-described configuration and the tie X21 with the bottle 3 drawn on it is mounted on a vehicle and the vehicle is driven, for example, on a snowy road, the elastic body 10 of the bottle 1 is cooled through the tire 1, and as shown in the original drawing. The expandable body 10, which was in the state shown in Fig. 2, was not able to protrude outward due to the reduced wetness, the low vehicle running speed, and the small outward centrifugal force exerted on the bottle body 8, and the bottle body 8 contracted. Its total length decreases by z4.

Therefore, since the base end side of the expandable body 10 is fixed to the pedestal 5 supported by the tread 2, the expandable body 10 is attached to the bottle main body 8 fitted in the stud bin 7, especially its tip is shown by a broken line. Push 1/Gero relative to the position.

Therefore, since the stud bottle 7 protrudes from the mirror-like surface 9 at the tip of the bottle body 8 which is relatively exposed to the outer surface of the tie 1, it exerts a sparring effect on the snowy road.

On the other hand, for example, when driving on a road without snowfall, or on a road with melting snow or ice in early spring (JI), the vehicle speed increases and the outward centrifugal force applied to the bottle body 8 increases. As the size increases, the elastic body 10 is heated due to the heat of friction between the tie hair 71 and the road surface as it travels, contrary to the above.

As soon as the expandable body 10 expands, it projects outward and pushes up the bottle body 8, and the tip of the stud bottle 7 sinks from the mirror-like surface 9 at the tip of the bottle body 8.

Therefore, the stud bin 7 is in a state where it does not press against the road surface, so it does not wear out the road surface, and the mirror-like surface 9 at the tip of the bin body 8 is smoothly exposed to the outer surface of the tie A21. The periphery of the tip of this type of sea urchin will not damage the road surface.

Further, in such a state, the stud bottle 7 is protected by the bottle body 8 and does not wear out, and the running resistance is reduced, so that it is possible to run while suppressing the combustion Yh.

Furthermore, Iζ, the recess G of the pedestal 5 at the base end of the stud bottle 7
exerts a suction cup action on the brake layer 4, so that the bottle 3 is firmly attached to the stud bottle 7, and the impact generated from the bottle 3 is absorbed by the solid elastic body 10 of the urethane rubber kidney. It can also be absorbed to reduce noise.

<Other Examples> It goes without saying that the embodiments of the present invention are not limited to the above-mentioned embodiments. For example, the material of the stud bottle, bottle body, etc. may be made of reramic or ductile cast iron,
Moreover, various embodiments can be adopted, such as making the material highly hard by hardening or the like, or providing a cell chamber in the urethane rubber elastic body.

<Effects of the Invention> According to the present invention, it is possible to reliably deal with road conditions on frozen roads, snowy roads, and normal road surfaces without the need for tire changes or de-necking work. Excellent effects can be achieved.

In addition, the stud bottle whose base end is supported by the tread passes through the bottle body, which has a mirror-like curved surface exposed on the outer surface of the tie 7, in a relatively slidable manner. 1Ilq movements are made smoothly,
Since it is possible to cover the stud bin in a manner that allows it to protrude freely from the bottle body, an excellent effect is achieved in that the stud bin can be automatically protruded according to the road surface condition.

In general, the pin body is made to be able to protrude freely from the tip of the stud pin through a solid elastic 14- made of urethane rubber interposed between the pin body and the base of the stud pin, so that it can be easily used on snowy roads. etc., the stud pins are relatively protruded, and can be retracted for normal roads, which has an excellent effect of allowing you to freely deal with road conditions. A will be given.

Therefore, when driving on a normal road surface that is not frozen, the stud pins will not wear out the road surface and will not cause dust pollution at the tip of the stud pin, and the stud pin will not wear out. 'Xi has excellent effects that can extend your life.

Furthermore, the mirror-like surface at the tip of the pin body lowers the frictional resistance against the road surface when the vehicle is driven on a normal road surface, which has the additional benefit of improving fuel efficiency.
