Abstract

PROBLEM TO BE SOLVED: To solve such a problem that although a studless tire is the mainstream of the tires used in the winter season, it remarkably drops braking performance on a freezing road, and a main cause of a serious accident arises there from. SOLUTION: An auxiliary tool obtaining the braking performance equivalent to a studded tire should be developed. Cemented carbide effectively used in the studded tire is embedded in a longitudinal groove of a tire to stabilize and to ensure the braking performance. A spring is used to make simply attachable and detachable and to also consider environmental problem. When the chain tool is fixed, the spring is contracted with a fixing metal fixture and a fixing block to make attaching and detaching easy.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a method for manufacturing a tire anti-slip device.

[0002]

2. Description of the Related Art Conventionally, various tire chains have been proposed as anti-slip on snowy roads and frozen roads. There are known tire chains made of metal chains and rubber or plastic tire chains. Further, a so-called spike tire in which a pin is directly embedded in rubber of a tire is known, and is effective on a frozen road surface. recently,
In some cases, pins are embedded in rubber-like bands and used in tire grooves, and in other cases, pins are swaged into wires.

However, the use of spiked tires has been restricted by administrative authorities due to problems such as dust pollution. As an alternative, statless tires have been used, but braking performance on icy roads and climbing performance are significantly inferior to spiked tires.

[0004] Further, a rubber-like material that fits into a groove of a tire is apt to come off during running and is liable to be cut because the strength of the rubber is weak.

[0005] In addition, a pin which is caulked to a wire is
There are disadvantages in that the strength of the pin is weak and lacks durability, and that the pin is short and lacks braking performance.

[0006] Accordingly, the spike tire has the braking property,
It proposes and proposes a detachable tire chain.

[0007]

The former spike pin is most effective on the frozen road surface of the high mountains in the northern cold season or the winter season. However, due to environmental issues, the use is limited to frozen road surfaces only. In view of the above, a method for stabilizing the vehicle so that the vehicle can be mounted and demounted so that the vehicle does not naturally desorb during traveling and maintain braking performance on a frozen road surface is proposed.

[0008] The present invention uses a cemented carbide spike pin, stabilizes it, does not spontaneously desorb during running, and can be easily mounted on frozen roads, and can be easily demounted on dry roads. Have been.

[0009]

The gist of the present invention to solve the above-mentioned problems and achieve the above-mentioned object is to fit a metal pin which is fitted into a longitudinal groove of a tire and has a hard material embedded in a material having high wear resistance. The solution is to form a rosary (chain) by passing the wire rope through a tube-shaped pipe.

[0010] In order to easily fit into the groove of the tire and to stabilize the pin during running to maintain the unity with the tire, a stable block made of a material having high wear resistance is integrated to protect the pin.

A spring is attached to the chain to prevent the chain from falling off during running by the centrifugal force caused by the rotation of the tire.

[0012] The shape of the pin is, for example, that a cemented carbide is embedded in carbon steel, formed into a flange shape, the lower part of which is thinned and embedded in a block. Open. Even if the road surface touches the tip of the pin and a force is applied, the shape of the pin itself does not sink into the block and the tire.

The stable block is made of a material such as plastic, metal, light metal ceramic, and rubber.
It is molded so as to fit into the groove of the tire, and the pin is embedded, and 12 holes are formed through which the wire rope passes.

The pins were embedded and the rope was rosary-shaped,
In order to keep the space between the blocks, a pipe made of nylon, urethane, metal coil, or the like is used.

A block in which a pin is embedded in a rope and a pipe are alternately passed to form a rosary. Make the rope an arbitrary length, crimp the end with a crimp terminal and attach a spring to make it circular.

A rope at one end is passed through the inside of the spring, and a rope at the other end is also pressed through the inside of the spring to stop each end with a terminal.

A metal or light metal tubular pipe (a linear body guiding ring, which also serves as a stopper for a crimping terminal; hereinafter, referred to as a "color") is placed outside the spring to smoothly expand and contract the spring.

[0018]

As described above, the tire chain of the present invention can easily be attached and detached while securing the braking performance of the former spike pin, and can be mounted on a frozen road surface while considering the environment. To prevent traffic accidents and enable safe driving.

The braking performance is maintained as long as the hard pin is provided, and the durability is excellent.

There is almost no load on the rope due to its structure, and there is very little fear of breakage.
