Problems solved by technology

However, the circumferential hole 1' through the circumferential direction will reduce the rigidity excessively, and the tire is prone to abnormal collapse, and the cushioning performance and durability of the tire cannot be guaranteed. The abnormal collapse of the tire will increase the friction area with the road surface, and the cruising range of the vehicle will decrease. However, if the design of multiple radial holes 2' is not properly configured, it will easily l

Example Embodiment

[0031]Example one

[0032]BelowFigures 2 to 6 A tire carcass structure of an embodiment of the present invention is described.

[0033]Such asfigure 2 withimage 3 As shown, according to an embodiment of the present invention, the carcass includes a head 10 and a neck 20, wherein the head 10 includes a head outer peripheral surface 11, a head side 12 and a head inner peripheral surface 13, neck The portion 20 includes a neck side 21 and a neck inner peripheral surface 22, and the neck 20 is provided on the head inner circumferential surface 13 and protruded toward the inner side of the tire, the inner peripheral surface 13, the neck side 21 and the neck The inner peripheral surface 22 coincides with the mating portion of the rim, and then the head 10 and the neck 20 are integrally designed, that is, the cross section of the carcass is present in a mushroom shape.

[0034]Among them, combinedFigure 4 withFigure 5 The neck inner peripheral surface 22 has a plurality of radial center holes 30 an...

Example Embodiment

[0045]Example 2

[0046]Bonded belowFigure 7 A tire carcass structure is described in Example 2 of the present invention.

[0047]According to an embodiment of the present invention, the entire structure and principle thereof are substantially the same as that of the embodiment, the same is no longer described, in the present embodiment, the radial cross section of the radial center hole 30 Trimming design. The radial center hole 30 has a ratio of the extended width W1 and the radial center hole 30 in the axial direction of the extension W2 of 103%, and the ratio is set to ensure that the tire body is in the nearby area of ​​the tire circumference. The weight and rigidity are reasonably reduced to ensure that the tire body has good support performance and buffering performance.

[0048]The radial cross section of the radial side hole 40 is then convex-forming design. The radial edge hole 40 is set to 200% in the ratio of the extended width W3 in the circumferential direction and the radial e...

Abstract

The invention provides a tire body structure and a non-pneumatic tire. The tire body structure comprises a head part and a neck part, the neck part is arranged on the inner circumferential surface ofthe head part and protrudes towards the radial inner side of the tire, and the inner circumferential surface of the head part, the side surface of the neck part and the inner circumferential surface of the neck part jointly define a matching part matched with a rim; a plurality of radial center holes and a plurality of radial side holes are evenly distributed in the inner circumferential face of the neck part at intervals along the whole circumference of the tire, the radial center holes are located in the axial center of the inner circumferential face of the neck part, and the radial side holes are symmetrically formed in the two sides of the radial center holes and distributed alternately with the radial center holes in the circumferential direction of the tire, the radial center holes and the radial side holes are perpendicular to the inner circumferential face of the neck part and extend towards the radial outer side of the tire; a plurality of axial holes are formed in the side surface of the head part and are communicated with the radial central holes in a one-to-one correspondence manner; the phenomenon of ring slipping between the tire and a rim can be avoided, it is ensured that the tire has good buffer performance and durability, and the endurance mileage of a vehicle is increased.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to a tire carcass structure and a non-pneumatic tire with the carcass structure. Background technique [0002] Electric scooters include not only electric leisure scooters loved by the younger generation of consumers, but also some scooters for the elderly and disabled. The former is mainly two-wheeled and has the advantages of portability, flexibility, and strong entertainment; the latter The latter are mainly light four-wheel vehicles, which are used to meet the daily transportation needs of the elderly and disabled with inconvenient legs and feet. In order to meet the needs of the above consumer groups, the above-mentioned electric scooter should have the characteristics of lightness, stable performance, simple maintenance or even maintenance-free. In order to make the vehicle meet the characteristics of lightness, stable performance, simple maintenance or even maintenance-free, no...
