Abstract

The invention provides a non-pneumatic tire comprising a rubber tread, a base rubber vulcanized to blend with the rubber tread to a whole and an elastic support body for supporting the rubber tread in order from outside to inside along the radial direction of the non-pneumatic tire, wherein the elastic support body comprises an inner pressure-bearing ring in contact with a wheel rim, an outer pressure-bearing attached to the base rubber and a middle support body arranged between the inner pressure-bearing ring and the outer pressure-bearing ring; and the middle support body comprises first support bodies and first axial through holes evenly distributed along the circumferential direction, and the first support bodies and the first axial through holes are sequentially arranged along the direction from the outer pressure-bearing ring to the inner pressure-bearing ring. The non-pneumatic tire disclosed by the invention can help to evenly and discretely transmit the grounding pressure of the non-pneumatic tire to the middle support body, so that the grounding tread imprint shape is excellent, the distribution of the grounding pressure is relatively even, and the grounding performance is good.

Description

technical field [0001] The invention belongs to the technical field of tires, in particular to a non-pneumatic tire. Background technique [0002] 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, when the pneumatic tire is punctured, it is easy to leak air, which weakens the bearing capacity of the tire, and will cause severe or irregular wear to the tire tread. When the inflation pressure in the tire is too high, the tire will burst, which will affect the driving safety of the vehicle. . Therefore, developing a kind of non-solid air-free tire with comfort, safety and durability becomes the top priority of automobile and tire industry. [0003] Chinese patent CN104999862A discloses a non-inflation safety tire, which is followed by a tread, an outer ring, a support body and an inner ring from the inside to the outside. In...
