Further, slip preventing claws 11 attached to a coupling member 8 cut through snow to prevent the occurrence of skidding. Meanwhile, an uneven part 16a of a lateral preventing tool 15 cut through a road surface to prevent the occurrence of a lateral slip. This constitution enables the occurrence of skidding and a lateral slip.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a tire spin prevention and skid prevention device,
In particular, the present invention relates to a tire slip prevention II and skid prevention device that can be attached to the tires of vehicles traveling on snowy or frozen roads to prevent the tires from spinning and skidding.

[Prior art and its problems]

Conventionally, when vehicles such as automobiles drive on snowy or frozen roads, chains are wrapped around the tires or snow tires or spiked tires are used to prevent slips and skids.

However, with tire chains, spiked tires, etc., the tires become more likely to spin as the amount of snow increases. This is because the above-described tire chains and spiked tires cannot sufficiently inject the chains and the like into the snow-covered road surface, and the snow is interposed between the road surface and the tires.

Furthermore, when a vehicle drives on a frozen road surface, there is a unique problem of not only slipping but also skidding of the tires. That is, when a vehicle enters a curved road from a straight road, the front wheels are directed along the curved road by steering wheel operation, but the vehicle body tends to move straight due to inertia. As a result, the rear wheels may skid, sometimes making it impossible to drive. When the brakes are applied suddenly, a similar phenomenon can cause skidding, which can lead to an accident. This is because the above tire chains and spiked tires cannot ensure a sufficient contact surface with the road surface, and especially because the chain etc. cannot be sufficiently injected into the frozen road surface.

[Purpose of the invention]

The present invention has been devised in view of the circumstances described in item 1, and its purpose is to prevent tires from skidding when driving on snowy or frozen roads. The object of the present invention is to provide a skid prevention and skid prevention device.

[Summary of the invention]

In order to achieve the above-mentioned object, the present invention has an annular member having upright blowing blades for shoveling snow and blowing it backwards, which is attached to both sides of the tire sidewall, and which connects these annular members with a plurality of connecting members. The annular member is characterized in that a skid prevention device that prevents the tire from skidding is provided on the annular member through a biasing member that protrudes from the tire tread, and the blower blades scrape snow as the tire rotates. The anti-skid device is energized by the biasing member and is firmly injected onto the frozen road surface due to the reaction force of the snow being shoved in and thrown backwards to prevent tires from spinning. ,
It is possible to prevent the tires from skidding, and even if the tires skid, it can be immediately closed.
