Abstract

PURPOSE:To aim at preventing a tire from slipping and the road surface from being damaged, by swingably providing a pawl having a frictional part on the road surface side, to a cushion rubber disposed in a groove in the tread surface of the tire so that the pawl is swung by means of the frictional part in accordance with a slip of the tire. CONSTITUTION:When a tire 9 rotating, for example, in the direction A, slips, a frictional part 2 making contact with the road surface 12 is also shifted with a certain delay from the rotation of the tire 9. Accordingly, a pawl is inclined from the vertical condition in association with the swing of the frictional part 2. That is, the pawl is turned to be inclined about the spherical part 4 of a bolt 3 as a fulcrum, and therefore, the tip (a) of the pawl 1 sticks into the road surface 12. As a result, the tire is inhibited from slipping. At this time the opposite side of the pawl tip (a) is received by a cushion rubber 7, and therefore, even though a strong force is exerted to the pawl tip (a), the inclination of the pawls may be maintained constant. Meanwhile, when the tire 9 does not slip, the tire 9 and the frictional part 2 are synchronously rotated together, and therefore, the frictional part 12 makes contact with the road surface so as to be retracted.

(Prior Art) Among winter tires, there are snow tires that have special grooves on the tread surface of the tires when driving on roads with compacted snow. Also, when driving on ice-covered roads,
Drive many spike pins into the tread surface of the tire,
In addition, the tip of the pin protrudes slightly from the tire tread surface so that it sticks into the ice burn road surface.
There are spiked tires. Many of these are commonly used and are highly effective in preventing slips. Recently, as an alternative to the above-mentioned spiked tires, there are studless tires that have improved grooves on the tread surface of the tires to be more effective on road surfaces such as icy roads.

Furthermore, even in the middle of winter, the road surface is now paved due to snow removal work. Therefore, when countless cars run on the paved road, the spiked tires they have installed will relentlessly scrape the paved road. The car dust generated has a negative impact on the human body, and is now a major social problem.

Therefore, when the friction part (2) shifts and moves, the claw (+) also moves, and the vertical shape 11! i (Fig. 1) and tilts as shown in Fig. 2. In other words, due to the force of displacement and movement of the friction part (2), the claw tilts as shown in Figure 2, using the spherical part (4) of the bolt (3) as a fulcrum, and the toe (a) of the claw (1) ) sticks to the road surface (12) to stop slipping and propel the car.Also, on the opposite side of the toe (a), the cushion rubber part (7) stops the holder, so the toe (a) Even if a strong force is applied, the angle of the claw (1) is maintained constant.
If you brake suddenly in the direction of arrow A), the tires (
9) stops rotating, but the tire slips in the direction of the arrow in Figure 1. However, in this case as well, due to the same action as at the time of starting, the friction portion (2) shifts to the opposite side of the sliding direction of the tire (9), and at the same time, the pawl (1) tilts and the tip of the toe (a ) sticks to the road surface (12) and brakes the car. Furthermore, if the Mrf wheel or the rear wheel slips in the lateral direction when the automobile curves on the above-mentioned road surface, the friction portion (2) simultaneously shifts in the lateral direction. Then, due to the same action as when starting or applying the brakes, the claw (1) tilts and the toe (a) sticks into the road surface (12), stopping the lateral slip and stabilizing the car. let

As described above, in the present invention, no matter which direction the tire slips (360 degrees), the claws (1) come out to prevent the tire from slipping. Furthermore, since the area of the nails (1) that stick into the road surface is large, there is no need to attach them innumerable numbers as in conventional spiked tires (pins).

Next, when an automobile with the tires of the present invention mounted thereon runs on a paved road surface, the tires run almost without slipping. Therefore, when the tire does not slip, the friction part (2) and the tire (9) rotate in synchrony, so the friction part (2) does not move and the condition of the pawl (1) does not change. In that case, the friction part (2) contacts the road surface (12) and retracts, and the pawl (1) is pushed toward the center of the tire, but this is due to the soft rubber (filled inside the pawl (1)). (not shown) and the elasticity of the cushion rubber portion (7). When the tire (9) rotates and the friction part (2) separates from the road surface (I2), the elasticity of the rubber part causes
Return to original state. That is, the friction part (2) and the pawl (1) only repeat the downward movement, and only the rubber part forming the friction part (2) contacts the paved road surface. Therefore, there will be less wear on the paved roads and the generation of vehicle powder pollution will be kept to a minimum. Furthermore, if the paved roads are not damaged, the cost of maintaining them can be significantly reduced.
