Abstract

PURPOSE:To lift tiptoe faces against the road surface at the time of braking and prevent a slip simply and reliably by forming side grooves on a tire tread to provide the tiptoe faces and forming a functional space with the tiptoe face and an arch face adjacent to it. CONSTITUTION:Tiptoe faces 1 are slenderly and protrusively formed on the surface of a tire tread 5 perpendicularly or obliquely to the rotating direction of the tire. Side grooves 4 are formed along the tiptoe faces 1. A deep arch face 2 is formed in front of the tiptoe face 1, and a functional space 3 is formed with the tiptoe face 1 and the arch face 2. Thereby, the tiptoe faces 1 are pressed into the tread 5 by the contact with the road surface to compress the rubber material of the tread 5, the compressed rubber material repulses and applies pressure to the tiptoe faces 1, thus the tread pressure against the road surface can be improved. Accordingly, a slip can be prevented simply and reliably without requiring a spike tire, a chain, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION 0) Industrial Application Field The present invention relates to a device for preventing slippage and slippage of tires of automobiles, etc. when the road surface is in a slippery condition such as compacted snow or ice.

(b) Conventional technology When the road surface is abnormal, such as snowy or frozen, in automobiles, etc.,
Attach chains to tires to prevent slipping, or
Methods such as the use of spiked tires are being used.

(c) Problems that the invention aims to solve However, when driving on a normal road as it is, the wheels vibrate,
There were many drawbacks, such as the danger of cutting and flying at high speeds, and the damage caused by spiked tires on the road surface, so it was necessary to take appropriate measures to suit each road condition.

The object of the present invention is to prevent slippage by configuring a braking mechanism directly on the tread of the tire, without relying on methods such as attaching objects to the tire or using metal objects.

2) Means for solving this problem The present invention will be explained based on the drawings. FIG. 1 is a plan view showing a part of the tire tread pattern, and FIG.
It is an enlarged sectional view showing a part of the structure.

In FIGS. 1 and 2, the toe surface 1 is set on the surface of the tread 5 at a right angle or at an oblique angle to the rotational direction of the tire, and is raised in a long and narrow manner. Gutter 4
to establish its form on the tread. A deeply dug non-stepping surface 2 is provided on the front side of the toe surface 1, and a functional space 3 consisting of the mutual relationship between the toe surface and the non-stepping surface is provided.

(E) Function To explain the braking action on ice floes of a tire with the tread structure configured as described above, the toe surface, which is set as a long and narrow bulge on the tread, is pushed into the tread when it comes into contact with the road surface. Compress the rubber on the tread (arrow) 9, the compressed rubber will rebound (arrow) 101 Pressure on the toe surface (arrow)
11 (arrow), so it always has a stronger tread pressure than other treads.

(Figure 4) When you apply the brakes while driving, the tires stop rotating,
The vehicle body sinks due to the reaction, increasing gravity and applying pressure to the tires. On the other hand, the tire tread, which has been subjected to the deceleration effect due to the road pressure resistance of the toe surface, receives inertia load (arrow) 13 due to the competition between the vehicle weight force (arrow) 12 and the traveling inertia (arrow) 8.
It concentrates on the toe surface and further increases the tip pressure, inducing a strong toenail phenomenon against the road surface resistance (arrow) 14.

On a frozen water surface, the tip of the toe wipes away the pseudo-liquid layer 16 on the ice floe, absorbs and removes it (arrow) 15 into the functional space, and is conventionally thought to be the cause of sliding. 2, which occurs because the tread steps on the peeled off pseudo-liquid layer one after another.
As a result of preventing the next-slip phenomenon, the tire tread adheres closely to the road surface, increasing the pressure on the road surface and exhibiting a braking effect, thereby preventing slipping and slipping. (Fig. 5) (f) Example Fig. 3 shows a toe surface and a non-tread surface formed integrally, a functional space set within that shape, and a toe braking mechanism manufactured by implanting the toe braking mechanism into the tire tread. Another embodiment is shown in which it is fixed and has a gutter.

In this example, since the claw braking mechanism is manufactured independently,
It is easy to select the strength, size, rubber quality, etc. suitable for the application, and the installation configuration such as the implantation position can be freely configured.

(G) Effects of the Invention As explained above, this invention solves the problem by configuring anti-slip means in automobiles etc. directly on the tire tread. It is easy to adapt to road conditions without the need for installation, and the impact and benefits for drivers are significant.

In addition, it eliminates unnecessary effort on the road and improves the flow of traffic, which has the effect of leading to widespread industrial development.

Tires with this tread structure have a braking function and are capable of starting,
It also has a stepping effect from the toe surface during acceleration and pitching.
