Description

Woven tire chain

The present invention relates to a tire chain attached to a vehicle tire in order to increase friction between the vehicle and a road surface under winter conditions.

More specifically, the present invention relates to a textile tire chain that is attached to a vehicle tire as a slip stopper when traveling on a snowy road or a frozen road surface.

When driving on snowy roads and icy roads, change tires to normal ones, use spike tires, studless tires, etc. that have an anti-slip effect, and attach tire chains to the tires. It is common to prevent slipping.

In areas where the road surface is always covered with ice and snow in the winter, it is often the case that tires are replaced as described above. It is common to wear.

A tire chain includes a metal chain, a resin chain, and a fiber chain, and a fiber chain that is formed in a net shape using a rope has been proposed (for example, see Patent Document 1).

Further, a fabric anti-slip device has also been proposed as a fiber-mounted type that is not a chain (see, for example, Patent Document 2).

This woven tire chain is made of a woven fabric made of a material whose contact point with the road surface shows a good adhesion to the snow road surface. An elastic member is provided in a portion corresponding to the side surface of the tire, and the elastic force makes it easy to attach to and detach from the tire, thereby eliminating the need for jacking up when attached to the tire.

These fiber tire chains, such as rope tire chains and fabric tire chains, are lightweight and have excellent storage properties because they can be folded compactly.

Further, there has been proposed a fiber tire chain in which the relationship between the gap area of the mesh of the knitted fabric and the width of the strand of the knitted fabric when mounted on the tire is determined (see, for example, Patent Document 3).

Furthermore, a tire cord in which single fiber groups are obliquely oriented and a tire cord that is inverted are overlapped, and both sheets are sandwiched between two rubber sheets, integrated, and cut into a predetermined shape with a burr cutter. A tire anti-skid tool has also been proposed (see, for example, Patent Document 4).

Japanese Patent Laid-Open No. 7-156622 Special Table 2002-541007 JP 2007-284047 A JP-A-10-157424

The performance required for the tire chain is durability, braking performance on ice and snow, and climbing performance.

The tire chain using a rope is the same as the conventional metal chain or resin chain, but is changed to a rope, and the durability and braking performance specific to a fiber tire chain is not sufficient.

In the various embodiments shown in the above figures, the same reference numerals are used for similar or corresponding parts.
(Example 1)
This will be described with reference to FIGS. 1 to 4, 10, and 11. This embodiment is a mesh-type stretchable fabric tire chain.

The belt portion 1 made of a stretchable fabric that is mounted so as to surround the tread of the tire and is in contact with the road surface is made of a woven structure as shown in FIG. 4, and the warp yarn is 1120d carbon-containing polyurethane yarn 10 and 150d polyester. Two types of yarns are used: filament yarns and yarns 11 covered with polyurethane with heat-sealing yarns, and weft yarns are made by twisting 750d / 48F polyester filament 200 times per 1m, and weaving And woven to a width of 200 mm.

The seam for making the belt part 1 into a circle was sewn with a circumferential end overlapped by 2.5 cm. Further, the seam portion was reinforced with a 50 mm wide woven tape using a yarn obtained by twisting a polyester filament of warp yarn 250d / 24F 200 times per 1 m to reinforce the joint portion.

The belt portion 1 and the inside portion 4 provided adjacent to the belt portion 1 and facing the inside (inside wall portion 6) of the tire are integrally woven, and the warp yarn is a polyester filament of 250d / 24F between 1 m. A yarn twisted 200 times was used. The edge 5 of the inside portion 4 was used by bundling 16 yarns of synthetic rubber covered with polyester.

An elastic mesh 2 that is provided adjacent to the belt portion 1 and that covers the outside of the tire is provided as an outside portion that faces the outside of the tire. This stretchable mesh 2 was used by stretching a polyamide and polyester stretch knitted fabric over the entire outer surface of the tire by sewing, and further sewing a 25 mm wide polyester tape 3 in the radial direction into a cross.

Since the outer circumference of the tire used for the test run of the stretchable fabric tire chain (mesh type) having such a configuration was 190 cm, the outer circumference of the belt portion 1 was shortened to about 10% shorter than that, to 170 cm. did. In addition, the cutting of the belt part 1 was performed at 175 cm, and in order to maintain the strength, the end part in the circumferential direction was overlapped by 5 cm to form a joint part. The elastic knitted fabric of the mesh part 2 was made 48 cm in diameter and attached by sewing. On the surface, a polyester tape 3 having a width of 25 mm was attached in a cross shape after sewing.

The vehicle equipped with this stretchable fabric tire chain ran 100 km at an average speed of 40 to 50 km / h on the paved road, but the stretchable fabric tire chain was able to finish without dropping from the tires. As shown in the photograph after use in FIG. 13, no major surface change such as failure was observed on the surface of the stretchable belt.
(Embodiment 2)
This will be described with reference to FIGS. 5 to 7, FIG. 11, and FIG. The present embodiment is an open type stretchable fabric tire chain.

The belt portion 1 is made of a woven structure as shown in FIG. 4, and a warp yarn is a 1120d carbon-containing polyurethane yarn 10 and a yarn 11 covering a polyurethane with a 150d polyester filament yarn and a heat-sealing yarn. Two types of yarns were used, and the weft yarn was a 750d / 48F polyester filament twisted 200 times per 1 meter, and weaved to a width of 200 mm by twine weaving.

The outside portion 16 provided adjacent to the belt portion 1 and facing the outer side of the tire is annular, woven integrally with the elastic belt portion 1, and a warp yarn using a 150d / 2 polyester filament. Further, the edge portion 17 was used by bundling 16 pieces of # 38 synthetic yarn rubber covered with a 150d polyester filament yarn, and woven to a width of 200 mm by entanglement. Further, three polyester tapes 3 having a width of 25 mm were attached to the outside portion 16 in the radial direction.

The inside portion 4 provided adjacent to the belt portion 1 and facing the inside of the tire was woven separately with a woven structure such as 14 in FIG. The warp yarn of this woven structure was a 150d / 2 polyester filament yarn, and the warp yarn for expansion and contraction was a 150d polyester filament yarn covered with # 38 synthetic rubber. The edge 5 was made of 16 bundles of synthetic rubber covered with polyester filament yarn. Such a woven fabric having a width of 50 mm was used as the inside portion 4 and attached to the belt portion 1 by sewing.

Since the outer circumference of the tire used for the test run of the stretchable fabric tire chain (open type) having such a configuration is 168 cm, the outer circumference of the belt portion 1 is shortened by about 12% to be 147 cm. . The belt portion 1 was cut at 150 cm, and the end portions in the circumferential direction were overlapped by 2.5 cm to maintain the strength, thereby forming a connecting portion.

A running test was performed in the same manner as the mesh type described above, but the stretchable woven tire chain was not broken and was not dropped.
(Embodiment 3)
The difference between the third embodiment and the second embodiment is that the shape is the same and the material is different.

The belt portion is made of a woven structure as shown in FIG. 8, and the warp yarn is made of two types of yarns: 1120d polyurethane 10 and 150d polyester filament yarn 11 covered with # 38 synthetic rubber. The weft used was a yarn in which a polyester filament of 750d / 48F was twisted 200 times per 1 m, and woven into a width of 150 mm by leno weaving.

The inside part was woven separately in the woven structure diagram of FIG. The warp yarn 12 is a 150d / 2 polyester yarn, the elastic warp yarn is a synthetic yarn rubber 18, the edge 17 is a bundle of 16 synthetic yarn rubbers, and the weft yarn 9 is a polyester 150/2. Two of them were used together and woven to a width of 55 mm.

The outside part was woven separately in the woven structure diagram of FIG. The warp yarn 12 is a 150d / 2 polyester yarn, the elastic warp yarn is a synthetic yarn rubber 18, the edge 17 is a bundle of 16 synthetic yarn rubbers, and the weft yarn 9 is a polyester 150/2. Two of them were used together and woven to a width of 55 mm.

A running test was conducted in the same manner as in the second embodiment, but the elastic fabric tire chain was not broken and no dropout was observed.
"Comparative example"
The belt was tested on snow with a rubber woven fabric and a bag-woven stretch belt, but the braking distance was almost the same as that of a tire not fitted with a tire chain, and no braking effect was seen. In addition, the woven fabric with rubber usually has a weight of the woven fabric itself. When the speed is increased, it contains snow moisture and becomes heavier and falls off the tire.

Also, since the polyester filament is usually used, the belt part broke in the sudden braking on the dry road, the dry asphalt and the concrete running test.
