Abstract

A non-pneumatic tire having a block type reinforcement configuration includes: a tread unit that forms an outer portion of the tire and comes in contact with a road surface; a wheel unit that is connected to an axle; a spoke unit that is formed between the tread unit and the wheel unit; and a block type reinforcement unit that includes a block formed inside the tread unit in the circumferential direction of the tread unit, and a plurality of reinforcing members formed in the block to correspond to the shape of the block.

Claims (12)

1. A non-pneumatic tire having a reinforcement configuration, the non-pneumatic tire comprising:

a tread forming an outer portion of the tire to come in contact with a road surface;

a wheel connected to an axle;

a spoke disposed between the tread and the wheel; and

a reinforcement unit including a plurality of blocks disposed inside the tread in a circumferential direction of the tread, each of the plurality of blocks having a plurality of reinforcing members disposed therein, the plurality of reinforcing members disposed in each block forming two or more layers of reinforcing members, each of the plurality of reinforcing members being in a wire shape,

wherein rigidity of the tread is adjusted by adjusting a number and position of the plurality of reinforcing members,

wherein the plurality of blocks are arranged in upper and lower rows, and

wherein a first set of blocks arranged in the upper row are spaced apart at a first distance, and a second set of blocks arranged in the lower row are spaced apart at a second distance, the first distance being different from the second distance.

2. The non-pneumatic tire of claim 1 , wherein the plurality of reinforcing members are made of one or more materials selected from steel, glass fiber, or carbon fiber.

3. The non-pneumatic tire of claim 1 , wherein the plurality of blocks are made of one or more materials selected from rubber, urethane, synthetic resin, or silicon.

4. The non-pneumatic tire of claim 1 , wherein each of the plurality of blocks has a circular, rectangular, pentagonal, or uneven cross-sectional shape.
