Description

Non-explosive tire wheel tire structure

The present invention relates to a tire structure, and more particularly to a tire structure that does not burst tires.

A typical tire is a ring-shaped rubber product with a substantially U-shaped cross section, which is installed in cooperation with a wheel frame to form an inflatable wheel, which serves as the main device for the vehicle to contact the ground. Tires must maintain a certain grip and anti-slip effect to ensure the safe driving of the vehicle; therefore, the tire tread is usually provided with several continuous or laterally extending grooves (commonly referred to as tread patterns). Existing tires rely on their tread It has a plurality of different tread patterns to form a tread with a high and low drop. It can generate appropriate friction (grip) with respect to the ground during driving to prevent the vehicle from slipping out of control during driving.

As we all know, after the vehicle travels for tens of thousands of kilometers, the tire tread is worn to a depth of less than 6mm, and the tire grip deteriorates, causing the vehicle to easily slip and run out of control, or even burst a tire. A traffic accident may occur, which threatens life and property.

Moreover, tire cut resistance is an important characteristic, especially when tires are specifically designed for off-road use, such as light truck radial tires and sports RV tires (called RLT tires). In particular, the side walls of the tire may be cut or cut by various external threats. In the conventional technology, it has been disclosed that a high-tensile strength aramid fine fiber of a cord type has been incorporated into the two sidewalls of the tire as a mechanical reinforcement. Load-bearing structure. Generally speaking, these aramid filaments are present as continuous filaments in order to provide strong and powerful mechanical properties. Many literatures have revealed that various types of continuous fine fibers, including aramid continuous fine fibers, are used in combination with metal wires or other inorganic continuous fine fibers for tire load bearing. In general, it does help tire load, but it does not improve the cut resistance of the tire substantially.

The purpose of the present invention is to provide a wheel tire structure, which has a double-layer anti-slip groove design. The first layer of grooves is located on the tread, and the second layer of grooves is hidden in the tire skin.
