Problems solved by technology

Non-pneumatic tires mainly refer to solid tires. Solid tires are completely composed of rubber and the manufacturing process is simple, but the tires are heavy and have poor shock absorption effect, which is not conducive to buffering the impact force from the road.

Abstract

The invention belongs to the technical field of tires and specifically relates to a non-pneumatic tire, in particular to the non-pneumatic tire of an annular corrugated structure. The non-pneumatic tire comprises a rim. A tread, a buffer layer and a rim matching component are sequentially arranged on the rim from outside to inside. The tread is sequentially composed of tread rubber, a transitional rubber sheet I, all-steel cords and a transitional rubber sheet II from outside to inside. The buffer layer is of an annular corrugated structure. Wave crests of the buffer layer are tightly attached to the inner side of the tread. Wave troughs of the buffer layer are tightly attached to the outer side of the rim matching component. A Reuleaux triangle space is formed between the buffer layer and the tread, and a Reuleaux triangle space is formed between the buffer layer and the rim matching component. The buffer layer and the rim matching component are fixed through a U-shaped buckle. By the adoption of the non-pneumatic tire, the flat tire problem of a pneumatic tire is solved, the buffer performance is good, and a manufacturing technology is simple.

Description

technical field [0001] The invention belongs to the technical field of tires, in particular to a non-pneumatic tire, in particular to a non-pneumatic tire with a ring wave structure. Background technique [0002] Tires are generally divided into pneumatic tires and non-pneumatic tires. At present, pneumatic tires are commonly used in the market. Pneumatic tires use rubber to seal the compressed air, and provide skeleton support through rubber-bonded steel wires or cords. After complex molding, vulcanization and other processes, a ring-shaped rubber tire with a cavity inside is formed. , The tire is assembled with the rim to form a closed space to seal the compressed air. Pneumatic tires have high elasticity, so that the car has good cushioning performance when passing through the tires. However, pneumatic tires often encounter the problem of puncture, over-inflation, under-inflation, tire cracks, or direct punctures. In order to avoid accidents when driving, it is necessar...
