Abstract

PURPOSE:To prevent abrasion of a pin and generation of dust by forming a spike tire pin for snow-covered road in such a manner as the tip of a stud pin, in an expansion/contraction body of temperature difference operation type supported in a tread, can project from and sink into the outer face of the tire. CONSTITUTION:Because of travelling on a snow-covered road, an expansion/contraction body 10 is cooled and Freon gas in a chamber 12 of said body 10 contracts, and the full length of said body 10 is reduced by DELTAl due to bellows 13, then a pin main body 8 is pulled into a tire, and a stud pin 7 relatively comes to appear on the tread face to show the function of spiking. When the temperature is raised due to travelling off the snow-covered road, the expansion/contraction body 10 is expanded and the stud pin 7 sinks into a mirrorface-like face 9, so the function of spiking is extinguished. Thus, projection and sinkage of the pin are performed according to a condition of the road surface so that environmental pollution can be prevented.

Description

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

<Explanation of the gist> The present invention is a bottle used for spiked tires of vehicles when driving on frozen roads in winter, and the tip is formed to be exposed on the outer surface of the tire and presses against the snow surface etc. This invention relates to a stud tire bottle 14%j that lowers the freezing point and provides a spike effect, and in particular, a stud bottle whose base end is supported on the red of the tire.
It slides freely through the pin body whose tip is exposed on the outer surface of tie A7, and the pin body can freely protrude to the tip of the stud bottle through a temperature difference actuated expandable body supported by the lead. This invention relates to a pin 47/1 j% of a spiked tire, in which the stud pin is relatively freely protruded from the mirror-like curved surface of the pin body.

<Prior art> In general, in snowy regions, there is snow on the roads in winter, and melted snow freezes at night, so vehicles equipped with normal tires tend to slip and roll.
In addition, because it is extremely dangerous, they are equipped with chains and spiked tires to prevent this.

Vehicle running stability is particularly good in snowy regions where snowfall on the road surface must be constantly dealt with.
Spiked tires are often used because they are safer and less troublesome to install and remove compared to those installed on tires.

However, as is well known, spike tires traditionally have a tie (the tip of the bottle body, which is cast into 7 ☆; 1:).
By exposing the tip to the outer periphery, when the tip is pressurized against the snow surface etc., the falling ice and snow can be used to melt the ice and snow and bite into the road surface to prevent slipping.

<Problems with the conventional technology> However, the bottle structure of the conventional spiked tire mentioned above has
However, as the popularity of ``3'' increases, the bottle always protrudes from the road surface, which has the disadvantage that the road surface is worn out during the dry season after ice and snow melt, and the bottle itself is also severely worn. 1. To deal with this, a mechanical four-piece structure that allows the bottle body to protrude as needed has been devised, but the structure is complicated and impractical, and it is difficult to manufacture. death! l! There were also people who said they wanted +1.

Furthermore, when there is no snow on the road surface, the road surface is scraped off by the 1-bin, and the dust generated from the road surface becomes a pollution problem around the passage.

In addition, the bottle scratches the road surface (there is also the disadvantage that fuel efficiency decreases due to increased running resistance).

<Purpose of the Invention> The purpose of the present invention is to solve the problems of the pin structure of spiked tires based on the above-mentioned prior art as a technical problem to be solved, and to prevent damage to the road surface as well as to maintain the tie V function against ice and snow. At the same time, the pin structure of the excellent spiked tire is beneficial to the field of automobile use in the transportation industry by minimizing the wear of the bins and preventing dust pollution generated around walkways in early spring when snow melts and the road surface is exposed. We aim to provide the following.

<Structure of the Invention> In order to solve the above-mentioned problems, the structure of the present invention, which is based on the above-mentioned object and the gist of the above-mentioned claims, is to solve the above-mentioned problem. As the temperature becomes low, the elastic body supported by the tread 3- contracts, and the stud bottle whose base end is supported by the tread causes the sliding movement L'1 to f.
Since the threaded bottle body causes the stud bottle to protrude relatively from the mirror-like curved surface at its tip, the stud bottle protrudes to the outside of the tie V and gives a spiking effect to the snow surface due to the freezing point lowering effect. When driving, the tires roll and I'? Contrary to the above, the extensible body extends and the stud bottle retracts relative to the bottle body, so that the tip of the stud bottle does not press against the road surface. This was achieved by taking technical measures to

<Embodiment - Configuration> Next, one embodiment of the present invention will be described below based on the drawings.

As shown in FIG. 1, a large number of bottles 3, which constitute the gist of the present invention, are buried in the tire 1' and red 2.

The bin 3 is provided with an umbrella-shaped pedestal 5 made of titanium alloy and protruding outward and abutting against the ply layer 4 within the tire 1.

4- A recess 6 is formed in the center of the pedestal 5 on the ply layer 4 side, and has an edge contact with the ply layer 4 to provide a reliable suction cup effect.

Further, a titanium alloy stud bin 7 is erected in the center of the pedestal 5 on the outer surface side of the tire 1.
A titanium alloy bottle body 8 is slidably fitted into the bottle body.

The bin body 8 is formed into a curved hemispherical shape with a mirror-like surface 9 at the tip, has a total length that can be smoothly exposed from the outer surface of the tire 1, and is shorter than the stud bin 7 by a set length Δl. , the stud bottle 7 is configured to protrude 84 by /β relative to the bottle body 8.

Between the pedestal 5 and the bottle body 8, a cylindrical phosphor bronze temperature difference actuated expandable body 10 is fitted around the outer periphery of the bottle body 8 through which the stud bottle 7 is passed.

The expandable body 10 has its proximal end screwed onto the pedestal 5, and its distal end side press-fitted into the small diameter portion 11 of the bottle body 8. Furthermore, the center portion is filled with 'tL Freon gas having a large coefficient of thermal expansion. An expansion chamber 12 filled with
has bellows 13 on its inner and outer walls.

<Embodiment - Effect> In the above-described configuration, when the tire 1 equipped with the bottle 3 is mounted on an IT vehicle and runs on a snowy road, the elastic body 1
0 is cooled and the Freon gas in the expansion chamber 12 of the expandable body 10, which was originally in the state shown in the drawing, contracts, and the total length of the expandable body 1o is reduced by Δ due to the bellows 13.

Then, the proximal end side of the elastic body 10 is 1 to 1 knot 2Cc,
Since it is fixed to the pedestal 5 held by 34, the elastic body 10
' pushes down the bottle body 8 fitted into the stud bottle 7 to the position shown by the broken line.

Therefore, the stud pin 7 protrudes from the mirror-like surface 9 at the tip of the pin body 8 which is relatively exposed to the outer surface of the tire 1, and therefore exerts a spike effect on the snowy road.

On the other hand, for example, when driving on a path without snowfall or on a path in early spring when snow and ice are melting, the elastic body 10 is heated due to frictional heat between the tires 1 and the road surface, contrary to the above.

The Freon gas in the expansion chamber 12 of the expandable body 10 expands, and the expandable body 10 expands via the bellows 13 and pushes down the bottle body 8, causing the tip of the stud bottle 7 to sink into the mirror surface 9 at the tip of the bottle body 8. do. .

Therefore, since the stud bin 7 does not press against the road surface, it does not damage the road surface, and the mirror-like surface 9 at the tip of the bin body 8
Since the tip is smoothly exposed on the outer surface of the tire 1, the periphery of the tip does not damage the road surface unlike the conventional type.

Furthermore, the stud bottle 7 is protected by the bottle body 8 and does not wear out, reducing running resistance and allowing the vehicle to run with reduced fuel consumption.

Furthermore, since the recess 6 of the pedestal 5 at the base end of the stud bin 7 provides a suction cup effect to the ply layer 4, the stud bin 7
Through this, the bottle 3 is securely attached to the bottle 3, and the impact generated from the bottle 3 can be absorbed and noise can be reduced.

17 = <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, pin body, etc. may be ceramic or solid cast iron,
In addition, the elastic body may be cylindrical in shape with its base end supported by 1 to 1 knot.
In addition, various embodiments can be adopted for filling the expansion chamber, such as ammonia or the like as long as the material has a large coefficient of thermal expansion.

<Effects of the Invention> As described above, the present invention has an excellent effect of being able to reliably deal with road conditions on frozen roads, snowy roads, and normal road surfaces without the need for changing tires or removing chains. is played.

In addition, the stud pin whose base end is supported by the tread slidably passes through the pin body, which has a mirror-like curved surface exposed on the outer surface of the tire. The movement of the bottle body is made smooth, and the stud bottle can be protruded freely relative to the bottle body, resulting in a smooth effect that allows the stud bottle to protrude depending on the road surface condition. It is played.

Furthermore, the pin body is made to be able to protrude freely from the tip of the stud bin via a temperature differential actuated expandable body supported by the tread, so that the stud bin can be relatively protruded on snowy roads, etc. For normal roads, it can be retracted and has the excellent effect of being able to freely deal with the road surface.

Therefore, when driving on a normal road surface that is not frozen, the stud bins will not damage the road surface and cause dust pollution in early spring, and the stud bins will not wear out, thereby extending the life of the tire. An excellent effect that can be extended is achieved.

Furthermore, the mirror-like surface at the tip of the bottle body lowers the frictional resistance against the road surface when driving on normal roads, which has the additional benefit of improving fuel efficiency.

A bottle structure of a spike tie A7, characterized in that the bottle body can freely penetrate through the stud bottle and protrude from the tip of the stud bottle via a temperature difference actuated expandable body supported by a tread. DETAILED DESCRIPTION OF THE INVENTION Classification/Field> The disclosed technology belongs to the technical field of the bin structure of spiked tires for snow-resistant roads mounted on vehicles. / Commentary on the subject matter> The present invention is an anti-slip bottle used for spiked tires when running on frozen roads in winter, the tip of which is exposed on the outer surface of the tire and which prevents slipping on snowy surfaces. This invention relates to a stud bottle structure for a spiked tire that provides a spike effect by pressing down on the tire to lower the freezing point T. In particular, a stud bottle whose base end is supported by the tread of the tire has a tip exposed on the outer surface of the tire. The bottle body is made to be able to freely protrude from the tip of the stud bottle via a humidity differential actuated expandable body supported by the tread, and as a result, the stud bottle is relatively slidably penetrated through the bottle body. This invention relates to a spiked tire bottle structure that can freely protrude from a mirror-like curved surface of a bottle body. <Prior art> In general, in snowy regions, there is snow on the roads during the winter, and melted snow freezes at night, making it difficult for vehicles equipped with normal tires to slip and be extremely dangerous. For this reason, we have dealt with this by installing chains and spiked tires. 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 eliminating the hassle of attaching and detaching. So-called spiked tires are often used due to their advantages. The principle of spiked tires is well known. Conventionally, spiked tires are formed by casting or driving into the tire so that the tip of the bottle body is integrated with the tire and is exposed to the outer periphery of the tire. In contrast, when the tip is pressed under pressure, the drop in the freezing point of the ice and snow is used to melt the ice and snow and penetrate it into the road surface, thereby preventing slips. <While considering the problems of the conventional technology, in the conventional spike tie Maru 7 bottle structure mentioned above, the bottle always protrudes from the road surface, so as the popularity increases, it becomes difficult to use during the transition to the dry season after melting ice and snow. The problem was that the road surface was worn out and the bottle itself was also heavily worn. To deal with this, various mechanical structures have been devised that allow the bottle body to protrude from the tie 17 surface as needed when driving on icy and snowy roads, but these structures are complicated and are not practical. However, there was also the drawback that it was produced in a foreign country. 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 locreto, etc., and the dust generated from the road surface becomes a pollution problem around the road. In addition, there is a disadvantage that running resistance increases as the bottle sweeps the road surface, and fuel efficiency deteriorates accordingly. <Object of the Invention> The object of the present invention is to solve the problems of the bin structure of spiked tires based on the above-mentioned prior art as a technical problem to be solved, as well as to maintain the originally excellent function of spiked tires against ice and snow. This is an excellent product that benefits the field of automobile use in the transportation industry by preventing road surface wear and tear, suppressing bottle wear as much as possible, and preventing dust pollution that occurs around roads in early spring when snow melts and the road surface is exposed. The present invention aims to provide a bin structure for spiked tires. 3-〈Structure of the Invention〉 In accordance with the above-mentioned object) The structure of the present invention, whose gist is the scope of the present patent claims, is to solve the above-mentioned problem when a vehicle runs on a snow-covered road or an icy road. When the spiked tires of the vehicle become cold, the expandable body supported by the tread contracts, and the stud bottle whose base end is supported by the tread causes the bottle body, which is slidably penetrated by the stud bottle, to collapse at its tip. In order to make the stud bottle relatively protrude from the mirror-like curved surface of the tire, the stud bottle protrudes from the outer periphery of the tire and gives a freezing point lowering effect f9 on ice and snow, giving a spike effect to the snow surface.On the other hand, when driving on a normal road surface, When the tire rolls and becomes high temperature due to frictional resistance, etc., the extensible body expands, contrary to the -L action, and the stud bottle retracts and retracts relative to the bottle body, causing the tip of the stud bottle to It takes technical measures to reduce running resistance without pressing on the road surface, and to prevent damage to the road surface. <Embodiment - Configuration> Next, an embodiment of the present invention will be explained as follows based on the drawings. As shown in FIG. 1, a large number of bottles 3 are embedded in the tread 2 of a tire 1, which is not the gist of the present invention. The bin 3 is provided with an umbrella-shaped pedestal 5 made of titanium alloy and projecting outward, which abuts the ply layer 4 within the tire 1 at its base. At the center of the pedestal 5 on the ply layer 4 side, four parts 6 are provided.
is formed so as to make edge contact with the ply layer 4 and provide a reliable suction cup action to assist integration and prevent detachment. Further, a titanium alloy stud bin 7 is erected and integrated in the center of the pedestal 5 on the outer surface side of the tire 1 by appropriate means, and a titanium alloy bin body 8 is slidably mounted on the stud bin 1. It is fitted. The bottle main 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 can be smoothly exposed from the outer surface of the tire 1, and has a set length / The lower side is shortened and the lower end is sealed, so that the stud bottle 7 is relatively shorter than the bottle body 8 by 2! only J: allowed to stand out. Between the pedestal 5 and the bottle body 8, a cylindrical phosphor bronze differentially actuated elastic body 10 is fitted around the outer periphery of the bottle body 8 through which the stud bottle 7 is passed. . When the base end of the expandable body 10 is screwed and fixed to the pedestal 5, the distal end thereof is press-fitted into the small diameter portion 11 of the bottle body 8, and the interior of the expandable body 10 undergoes thermal expansion. An expansion chamber 12 filled with Freon gas having a high filling rate is formed, and a bellows 13 is formed on the outer wall of the expansion chamber 12. <Embodiment - Effects> In the above-described configuration, when the tire 1 equipped with the bin 3 is mounted on a vehicle and the vehicle is driven, for example, on a snowy road, the elastic body 10 of the bin 1 is cooled through the tire 1, and the extensible body 10 of the bin 1 is cooled as shown in the original drawing. As the Freon gas in the expansion chamber 12 of the expandable body 10 is contracted, the total length of the expandable body 10 is reduced by /l due to the bellows 13. Therefore, the base end side of the expandable body 10 is fixed to the pedestal 5 supported by the tread 2. Therefore, the expandable body 1O-6= is fixed to the bottle body 8 fitted in the stud bottle 7, especially its tip. Press down relative to the position indicated by the dashed line. Therefore, since the stud pin 7 protrudes from the mirror-like surface 9 at the tip of the pin main body 8 which is relatively exposed to the outer surface of the tire 1, it exerts a spiking effect on the snowy road. On the other hand, for example, when driving on a road without snowfall, or when driving on a road with melting snow or ice in early spring, the elastic body 10 is heated due to frictional heat between the tire 1 and the road surface, etc. Ru. The Freon gas in the expansion chamber 12 of the expandable body 10 expands, the expandable body 10 expands via the bellows 13, pushes down the bottle body 8, and the tip of the stud bottle 7 is brought into contact with the mirror-like surface at the tip of the bottle body 8. It degenerates inward and disappears. Therefore, the stud bin 7 is in a state where it does not press against the road surface, so the road surface is not damaged, and the mirror-like surface 9 at the tip of the bin body 8 and the tip are smoothly exposed to the outer surface of the tire 1. Therefore, unlike the conventional type, the periphery of the tip does not wear out the road surface. Furthermore, in such a state, the stud bottle 7 is protected by the bottle body 8, so it does not wear out, and running resistance is reduced, allowing the vehicle to run with reduced fuel consumption. Furthermore, since the concave portion 6 of the pedestal 5 at the base end of the stud bottle 7 provides a suction cup effect to the ply layer 4, the bottle 3 is securely attached via the stud bottle 7, and the bottle 3
It can also reduce noise by absorbing shocks generated by <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 ceramic or ductile cast iron,
In addition, hard marks may be formed by quenching, etc., the expandable body may be cylindrical with its base end supported by the tread, and the material filled in the expansion chamber may have a large coefficient of thermal expansion. Numerous embodiments can be adopted, such as ammonia or the like. <Effects of the Invention> As described above, the present invention has an excellent effect of being able to handle road conditions reliably on frozen roads, snowy roads, and normal road surfaces without the need for changing tires or attaching/detaching chains. It is played. In addition, the stud bin, whose base end is supported by the tread, passes through the bin body, which has a mirror-like curved surface at the tip exposed on the outer surface of the tire, so as to be able to slide relative to the stud bin, so that the sliding of the bin body with respect to the stud bin is prevented. This is done smoothly and allows the stud bin to protrude freely relative to the bin body, which provides an excellent effect of automatically protruding the stud bin depending on the road surface condition. Furthermore, since the bottle body is made to be able to protrude from the tip of the stud bin via a temperature differential actuated expandable body supported by the tread, the stud bin can be relatively protruded on snowy roads, etc., and on normal roads. In contrast, by making it retractable, an excellent effect can be achieved that allows the driver to freely deal with road conditions. Therefore, when driving on a normal road surface that is not frozen, the stud bins will not cause damage to the road surface, and not only will there be no dust pollution in early spring, but the stud bins will not wear out. This has the excellent effect of extending the life of the tire.In addition, the mirror-like surface on the tip of the bottle body lowers the frictional resistance against the road surface when driving on a normal road surface, which has the side effect of improving fuel efficiency. There is also a dimensional advantage. 4. Brief explanation of the drawings The drawings are cross-sectional views of the overall structure of one embodiment of this invention. 1... Tire, 2...
