Abstract

PURPOSE:To secure safety travel on a frozen road while suppressing dust and noise on an ordinary road by installing pins which are not brought into direct contact with a road surface on an ordinary flat road and are operated only in the case of a slip in braking, staring, and climbing an upward inclination. CONSTITUTION:Pins 2 are slantingly mounted downward in the forward- backward direction in rubber 1 of a crown part of a tire. In ordinary travel, only the rubber 1 is brought into contact with a road surface and the pins 2 are not brought into contact with the road surface, while on a frozen road surface, the rubber 1 is pulled in the reverse direction to the advancing direction so as to be reversed because of a slip in braking, and as a result, the pins 2 are brought into contact with the road surface. Therefore, safety travel on a frozen road can be secured while suppressing damage of the road surface and the generation of noise in ordinary travel.

Description

Detailed Description of the Invention

[Industrial field of application] [0001] The present invention embeds a pin 2 in the crown portion of a tire to make it movable,
The present invention relates to an automobile tire mounted so as to operate only when slipping when braking, starting, or climbing a hill.

[Prior Art] Fixed pin type tires of automobiles have been recognized to be effective on frozen road surfaces, but when the paved road surface is exposed, the road surface is cut to cause vehicle powder pollution.

[Problems to be Solved by the Invention] This has the following drawbacks. (B) Except for frozen roads, the roads were cut because they were always in contact with the roads, causing vehicle pollution in urban areas, which became a social problem. (B) At present, even in cold regions, in most areas. Fixed pin tires have been banned and studless tires have become the mainstream, but accidents due to slip frequently occur, which is also a social problem.The present invention compensates for these drawbacks and ensures safe driving on frozen roads. Was invented as a highly effective winter tire

[Means for Solving the Problem] A structure in which a pin 2 is embedded in rubber of a crown portion of a tire from two directions and the pin 2 comes into contact with a freezing path when the rubber moves in two front and rear directions.

[Operation] Rubber 1 for crown portion of winter tire
As shown in FIG. 4, since the pin 2 is embedded obliquely in two directions, the pin 2 does not come into direct contact with the road surface during traveling.

[Examples] The present invention will be described below. (A) The rubber of the crown portion of the tire is installed as shown in the figure, and the pins 2 are attached to the rubber 1 so as to be obliquely downward in the front-rear direction. At this time, the pin 2 does not directly contact the road surface, but only this rubber 1 contacts.

[Advantages of the Invention] Since the present invention has the above-mentioned structure, when it is used, the road surface is in contact with the rubber 1 of the tire and the pin 2 is in direct contact with it during normal traveling as shown in FIG. The road surface is not damaged because it is not present. This rubber 1 is pulled in the direction opposite to the traveling direction and reverses by slipping during braking on a frozen road surface, and the pin exerts its effect. Also, when slipping at the time of starting a freezing road or climbing a hill, this pin and rubber Reverses in the opposite direction and its effect is obtained, but when the road surface is not frozen, it does not slip, so this rubber 1 and pin 2 are not pulled in either direction, and do not directly contact the road surface, other The crown part demonstrates the effect of the original abrasion,
It does not damage the road surface

Claims (1)

[Claims] 1. A winter automobile tire equipped with pins so that it operates only when braking on a frozen road surface without directly contacting the road surface on a normal flat road, when starting, or when slipping during climbing uphill.
