Bionic non-pneumatic tire

Abstract

The invention belongs to the technical field of tires. Aiming at the problems of poor shock absorption performance and high noise of the existing non-pneumatic tire, the invention provides a bionic non-pneumatic tire which sequentially comprises a tread, a connecting layer, a bionic buffer structure and a mounting body from outside to inside, the bionic buffer structure comprises a Z-shaped buffer plate imitating the hind limb of a feline, a honeycomb-shaped elastic body, a first outer ring and a first inner ring; the area among the Z-shaped buffer plate, the first outer ring and the first inner ring is filled with the honeycomb-shaped elastic body, and holes of the honeycomb-shaped elastic body is gradually enlarged from the first inner ring to the first outer ring. By means of the Z-shaped buffer structure and the rhombic honeycomb structure, the tire can effectively buffer large vibration and small vibration, the wind noise frequency is broken through, the wind noise of the inflation-free tire is reduced, and the problem that permanent deformation occurs due to insufficient strength of a single structure is solved.

Description

technical field [0001] The invention belongs to the technical field of tires, in particular to a bionic air-free tire. Background technique [0002] For a long time, the tires commonly used in vehicles are pneumatic tires. The superior cushioning performance and low rolling resistance of pneumatic tires have not been surpassed by other tires so far. However, pneumatic tires require regular tire pressure maintenance, are prone to puncture and air leakage, and have serious consequences for tire blowouts. Non-pneumatic tires, that is, tires that do not need to be inflated, do not rely on air, and only use the tire's own material and structure to achieve support and cushioning performance, such as solid tires, spring tires, buffer tires, etc. However, the existing non-inflatable tires generally have the defects of poor comfort performance, weak shock absorption capacity, high noise, and high fuel consumption. Therefore, it is difficult to popularize and apply them in the civili...
