Abstract

The invention provides a non-pneumatic tire with a rigid and flexible structure. The non-pneumatic tire mainly comprises two parts, namely a tire tread and a casing structure, wherein the tread part is mainly made of a thermoplastic elastomer, and the casing structure always extends from an inner surface of the tread to the center of a rim along the radial direction, so that the rim and the casing are combined into a whole; and the whole part is made of tough and elastic engineering plastics, an inverted conical through hole is formed in the casing part in the axial direction, and the inverted conical through hole is structurally characterized in that: holes positioned on two sides of the tire have the maximum diameter and a hole in the middle of the tire has the minimum diameter. The non-pneumatic tire with the rigid and flexible structure has the advantages of other non-pneumatic tires and is endowed with excellent structural performance and safety performance. In addition, because the casing and the rim are made of thermoplastic polymer materials, the mass of the tire is greatly reduced, and the non-pneumatic tire has a great significance for energy conservation, emission reduction and oil consumption reduction.

Description

technical field

[0001] The invention relates to a new type of tire, in particular to a non-pneumatic tire with a rigid-flexible structure, which can bear a certain load without inflation pressure. Background technique

[0002] Most of the tires in use today are pneumatic tires, which use compressed air to support the tires to bear a certain load. Compared with the previous solid tires, the comfort of passengers is greatly improved, but pneumatic tires also have great limitations. Pneumatic tires are prone to air leakage at the rim, and the loss of tire pressure caused by this leakage makes a larger area of ​​the tire bear the load, which further aggravates the wear of the tire, and the pneumatic tire is easy to be punctured, causing a blowout, etc. A series of adverse accidents have occurred, so after comprehensive consideration of the tire's comfort, safety and excellent durability, a variety of new non-pneumatic tires have come out.
