air-free tire

Abstract

The invention provides an inflation-free tire. The inflation-free tire sequentially comprises a rubber tire tread with patterns which have low rolling resistance and high grip strength, base rubber which is vulcanized into a whole with the rubber tire tread and an elastic support body achieving a support effect on the rubber tire tread from outside to inside in the radial direction of the tire. The inflation-free tire is characterized in that the elastic support body comprises an inner pressure bearing ring making contact with a rim, an outer pressure bearing ring attached to the base rubber and a middle support body located between the inner pressure bearing ring and the outer pressure bearing ring; first axial through holes are formed in a circumferential ring body of the outer pressure bearing ring, the axial section of each first axial through hole is shaped like one of a circle, an arch-shaped arc, an ellipse and a polygon of which the side number is larger than or equal to 6, and the first axial through holes are uniformly distributed in the circumference direction, so that a vehicle wheel axle uniformly transmits a load to the ground in a discretized mode through the first axial through holes of the elastic support body, grounding prints of which pressure is uniformly distributed are obtained, and the grounding property and the bearing property of the tire are improved.

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] The patent application with the application number 201510246208.6 discloses a non-inflatable hollow tire. The five buffer air cavities inside the tire carcass and the left and righ...
