Problems solved by technology

However, pneumatic tires also have a big safety shortcoming—easy to run and leak air. This phenomenon will lead to severe or irregular wear on the tire tread, not resistant to punctures, and even cause tire blowouts, which will affect the safety of vehicles.
Existing non-pneumatic tires adopt a long-spoke structure, which requires high fatigue strength of the material, and its vibration and noise problems are difficult to overcome, and the durability and comfort are limited

Abstract

The invention discloses an inflating-free tire, which comprises a rubber tire surface, base rubber and an elastic support body, wherein the rubber tire surface, the base rubber and the elastic support body are in sequential arrangement from outside to inside in the radial direction of the tire; the base rubber and the rubber tire surface are vulcanized into a whole; the elastic support body achieves a support effect on the rubber tire surface; the elastic support body comprises an outer pressure bearing ring attached to the base rubber, an inner pressure bearing ring in contact with a wheel rim and a middle support body positioned between the outer pressure bearing ring and the inner pressure bearing ring; the middle support body comprises first support structures and first axial through holes; the first support structures are uniformly arranged in the peripheral direction of the inside of the ring body of the outer pressure bearing ring; the first axial through holes are uniformly formed in a way of being separated from the first support structures. The inflating-free tire has the beneficial effects that the problems of tire air leakage, tire patching and tire bursting are solved; meanwhile, the inflating-free tire has good grounding performance and operation stability.

Description

technical field [0001] The invention belongs to the technical field of tires, in particular to a non-pneumatic tire suitable for passenger cars and new energy vehicles. Background technique [0002] With the widespread use of new energy vehicles, the safety, comfort, energy consumption and wear resistance of new energy vehicle tires are highly valued by automobile manufacturers. [0003] At present, most of the tires in use are pneumatic tires. Pneumatic tires use the high pressure of the compressed air in the tires to carry the load of the vehicle and have good riding comfort. However, pneumatic tires also have a big safety shortcoming—easy to run and leak air. This phenomenon will lead to severe or irregular wear on the tire tread, not resistant to punctures, and even cause tire blowouts, which will affect the safety of vehicles. Existing non-pneumatic tires adopt a long-spoke structure, which has high requirements on the fatigue resistance of the material, and the proble...
