open structure tire

Abstract

The invention provides an open-structure tire. The open-structure tire comprises a tread, a hub, a first rim ring and a second rim ring, wherein the first rim ring and the second rim ring are respectively clamped between the inner side of the tread and the outer side of the hub, the first rim ring and the second rim ring respectively comprise rims which are uniformly distributed around the axis of the hub, every two of the rims are adjacent to each other or connected with each other, each rim is connected with the inner side of the tread and the outer side of the hub, the first rim ring and the second rim ring are connected at a central radial plane of the tire, the first rim ring and the second rim ring are symmetrically or asymmetrically arranged, a plurality of closed annular hollow cavities are formed between the inner side of the tread and the outer side of the hub, and the plurality of closed annular cavities are clamped between the first rim ring and the second rim ring. By adopting the open-structure tire, the driving comfort and operability of the original open-structure tire can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of tires, in particular to an open structure tire. Background technique [0002] In the Chinese patent ZL201520481529.X, the applicant applied for a tube-type embedded open structure tire that will not blow out, including an outer ring and an inner ring. The outer ring is divided into symmetrical left and right sides by the tire center radial plane The outer ring and the right outer ring, the left outer ring and the inner ring are provided with a left rim ring, the right outer ring and the inner ring are provided with a right rim ring, and the left rim ring is connected to the right rim ring Connected to the radial plane of the center of the tire, the left rim and the right rim are connected to the inner ring and the outer ring, and when they touch the ground, the rim passes through the left and right sides connected to the outer ring. The two parts form a buffer structure, which can quickly distribute the ...

Problems solved by technology

[0003] However, the applicant found in the course of the test that when the left and right rims are arranged asymmetrically, the left and right rims along the longitudinal intersecting plane of the tire, that is, the radial plane area and the vicinity of the center of the tire, will Because the left and right rims are staggered and intersected in the radial plane area of ​​the center of the tire, the support force in this area and nearby is compared with the rim extending to both sides along the radial plane of the center of the tire compared with the left and right rims The ring area is strong, and regardless of whether the tread is flat or curved, the tire center radial plane and its vicinity become the maximum stress point. This kind of tire center radial plane stress enhancement is manifested as a decrease in comfort in flat tires, and it is not Under the ideal straight line and constant speed driving state, slight slippage is likely to occur due to changes in the road surface environment, and slight shaking is likely to occur under the curved tire performance of heavy load and non-ideal straight line and constant speed driving state
