Problems solved by technology

However, this kind of pneumatic tire has a complex structure, and there are more than 8 processes in the manufacturing process. In addition, the discharge of harmful substances can not be ignored, and it is necessary to check the performance and safety of the pneumatic tire at any time. The air pressure is absolutely crucial, so it is inconvenient to manage, and there are always safety problems such as tire damage caused by external objects and impacts during driving.

Abstract

According to the invention, there is provided a non-pneumatic tire including: a tread part having an outer circumferential surface at which a bent pattern is formed; at least one reinforcing structure part that is positioned between the outer circumferential surface of the tread part and an inner circumferential surface of the tread part so as to be inserted inside the tread part; a spoke part that is formed radially around a center of the tread part and is coupled to an inner surface of the tread part; and a rim part that has a diameter smaller than a diameter of an inner circumferential surface of the spoke part and has an outer circumferential surface which is coupled to the spoke part. The reinforcing structure part has a plain weave shape surrounded by an elastomer and is wound in a circumferential direction of the tread part.

Description

technical field [0001] The present invention relates to a non-pneumatic tire having a reinforcing structure part. More specifically, it relates to the use of a fabric-shaped reinforcing structure part inserted into the tread part in the circumferential direction of the tread part to support a load while increasing the height of the spokes. Non-pneumatic tires with reinforced structural parts for fatigue resistance. Background technique [0002] Nowadays, commonly used tires are divided into radial tires, bias tires, and solid tires according to their structures. Among them, most passenger cars and non-special purpose vehicles use radial tires, that is, pneumatic (or pneumatic) tires. However, this kind of pneumatic tire has a complex structure, and there are more than 8 processes in the manufacturing process. In addition, the discharge of harmful substances cannot be ignored, and it is necessary to check the performance and safety of the pneumatic tire at any time. The air ...
