Pollution-resistant and low-noise non-pneumatic tire that is easy to attach and detach {EASY INSTALLATION DIRTPROOF LOW NOISE AIRLESS TIRE}

The present invention relates to a pollution-resistant and low-noise non-pneumatic tire that is easy to attach and detach, and more particularly, to a pollution-resistant and low-noise non-perforated tire that is easy to attach and detach for preventing contamination of spokes and reducing noise generated by spokes It is about the entry tire.

In order to support the weight of vehicles, cargo and passengers and effectively absorb the impact force from the road surface, technology development for non-pneumatic tires in which the sidewall of the tire is of a spoke type is being actively developed.

However, the non-pneumatic tire has a problem in that noise is generated larger than that of the pneumatic tire because air passes through the space between the plurality of spokes during rotation.

In addition, there is a problem in that the spokes do not sufficiently absorb the impact force from the ground when a plurality of spokes are contaminated due to adhesion of foreign substances, or when snow and ice adhere to the spokes in winter.

In addition, the conventional non-pneumatic tire is manufactured in a state of being bonded to the wheel mounted on the vehicle, and in order to recycle the material of the tire that has reached the end of its lifespan, to remove the tire material attached to the metal wheel from the wheel, special equipment must be additionally used. There was inconvenience, and these dedicated equipment generated a large amount of carbon dioxide, so it was not eco-friendly.

Accordingly, there is a need for a non-pneumatic tire that generates less pollution and noise and is easy to mount and detach the tire material from the wheel.
