Tire body structure and non-pneumatic tire

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...

AI Technical Summary

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 lead to a decrease in the matching area between the inner peripheral surface of the tire and the rim. The surface is softened and sticky and wears out to produce rubber debris, which aggravates the slip ring phenomenon

Therefore, the air-free tires for electric scooters of the related art cannot ensure that the tires achieve an effective balance between cushioning performance, durability performance and anti-slip performance and improving the cruising range of the vehicle.
