Abstract

PURPOSE:To prevent a tire from slip without damaging a road surface by mixing numerous fibrous materials in a tread made of rubber of the tire to project the ends of the respective materials from the tread according to the irregularity of a road surface. CONSTITUTION:Numerous fibrous materials 1 are mixed in the proximity of the tread of a tire. The fibrous materials 1 are adapted to project respectively from the surface of rubber 3 forming the tread of the tire according to the slight irregularities of a snow-covered road surface 5 or the like. Such projecting fibrous materials 1 are hooked at the irregularities of the snow-covered road surface 5 or the like so that a frictional force between the tread of the tire and the snow-covered road surface is increased to prevent the tire from slip. On the other hand, on a dried road surface the rate of damaging the road surface by the fibrous materials 1 is reduced compared with that of conventional chain and spike to prevent the occurrence of environmental pollution of powder and dust.

On the other hand, there is the problem that spikes cause dust pollution. The spikes, which prevent slipping by digging into the snow, try to dig into the dry road in the same way, and as a result, end up scraping the pavement, creating dust. Also,
It also erases road markings.

The first step to solving the problem is to explain this invention using diagrams (see Figures 11, 21, and 3).A fibrous substance (1) (hereinafter simply referred to as fiber) is mixed near the contact surface of the tire. .

The fibers (1) are made to fluff up and protrude from the rubber (3).
By scratching the frozen compacted snow surface (5), it attempts to suppress slipping.

The working road surface (6) may be slippery or slippery under conditions of frozen compacted snow, and even if the surface is as smooth as a mirror, it is always slightly uneven; By applying this, it compensates for the decreased frictional force and suppresses slipping.

When the contact surface of the tire (3) contacts the frozen snow surface (5), a water film is formed between the contact surfaces due to the contact pressure. As a result, I? l Slip occurs due to reduced frictional force.

In order to increase the frictional force, this water can be removed, but it is difficult to do so completely.

As mentioned above, the frozen and compacted snow surface (5) always has unevenness. Therefore, scratching the fiber (1) is much easier and more effective in suppressing slippage.

If the example fiber (1) were hard like conventional spikes, it would damage the road surface in the same way, so it should have appropriate flexibility. Due to this flexibility, if more force than necessary is applied to the fiber (1) (such as force that scrapes the pavement surface), the fiber (1)
1) Since it bends and absorbs this force due to the elasticity of the rubber, it does not damage the pavement and does not generate dust. The flexibility of this fiber is what makes it so different from traditional hard spikes.

On the frozen snow surface (5), the scratching force (refractional repulsion force) of the fibers (1) acts to suppress slippage. In addition, this effect works both vertically and horizontally, so stable performance can be achieved even when driving straight or on curves. just,
Fiber (1) - If you look only at books, it's not as good as spikes, but
- By making each book thinner, even within a fixed area,
Since it is possible to increase the number to a degree that is incomparable to spikes, sufficient performance can be achieved. In this case, as the number of fibers (1) and rubber (3) increases, it becomes easier to separate them, so combining fibers (2) (Figure 4
Figure 51 (see Figures 6 and 7), fiber (1) and rubber (3
) to prevent the separation of the fibers (1) and at the same time prevent the fibers (1) from coming off.

4゜Example By changing the length, material, shape, number of fibers (1), etc., the properties of the tire can be changed, so they can be mixed according to the purpose. In addition, by using a material that does not wear out faster than the rubber material mixed in, and by using materials mixed at different depths at the same time, even if the tire wears, it will always protrude from the surface, resulting in improved performance. is maintained. In addition, by mixing fibers ( ) of various thicknesses, it is possible to cope with irregularities on the road surface that are not uniform in size, and by combining fibers (1) of different materials at the same time. This makes it possible to quickly respond to ever-changing road conditions, making the tire highly safe.
