Embodiment 1

[0070] like figure 1 , figure 2 , image 3 As shown, a run-flat tire system with a support ring disposed on the inner side of the tread includes a rim 11 , a support ring 21 , and a tire 31 that cooperate with each other. The rim 11 is an integrated deep groove rim adapted to the tire 31 , and the special feature is that the bead seat of the rim 11 is provided with a convex peak 1101 at one end close to the deep groove for preventing the bead of the tire 31 from loosening inward, and the rim The deep groove 11 is set to facilitate the disassembly and assembly of the tire 31 and also to cooperate with the support ring 21 to support the wheel in a deflated state. The flat-bottomed deep groove 1102; The groove bottom is configured as a flat bottom in the axial direction, and the axial width of the flat bottom is not less than 1 / 3 of the axial width of the rim 11 and not more than 2 / 3 of the axial width of the rim 11; the groove bottom edge of the flat-bottom deep groove 1102 ...

Embodiment 2

[0072] like Figure 4 , Figure 5 , Image 6As shown, a run-flat tire system with a support ring disposed on the inner side of the tread includes a rim 11 , a support ring 22 , and a tire 32 that cooperate with each other. The rim 11 is detailed in Example 1. The support ring 22 is basically the same as the support ring 21 in Embodiment 1, except that: (1) the axial width of the support ring 22 is equal to the axial width of the groove bottom of the flat-bottomed deep groove 1102 of the rim 11; (2) the support ring The circumferential outer ring 2201 of the tire 22 is set as an inner and outer layer, the outer layer part is called the outer layer 2201a, and the inner layer part is called the inner layer 2201b, wherein the outer circumferential surface of the outer layer 2201a fits the inner liner of the tread 3201 of the tire 32 On the inner circumferential surface of 3202, the thickness of the outer layer 2201a is not less than the thickness of the inner layer 2201b. In th...

Embodiment 3

[0074] like Figure 7 , Figure 8 , Figure 9 As shown, a run-flat tire system with a support ring disposed on the inner side of the tread includes a rim 11 , a support ring 23 , and a tire 33 that cooperate with each other. The rim 11 is detailed in Example 1. The support ring 23 is basically the same as the support ring 21 in Embodiment 1, except that: (1) the circumferential outer ring 2301 of the support ring 23 is set as a first circumferential outer ring 2301a and a second circumferential outer ring 2301b; The outer circumferential surface of the outer ring 2301a fits the inner circumferential surface of the inner liner 3302 of the tread 3301 of the tire 33, and the axial width is equal to 1 / 3~ 1 / 2; the second circumferential outer ring 2301b is arranged between the first circumferential outer ring 2301a and the circumferential inner ring 2302, and the radial distance between the second circumferential outer ring 2301a and the first circumferential outer ring 2301a is...

Abstract

The invention discloses a run-flat tire system with a support ring arranged on the inner side of a tread, which comprises a rim, a support ring and a tire which are matched with one another, and is characterized in that the rim is provided with a flat-bottom deep groove which is convenient for disassembling and assembling the tire and matches the support ring to support a wheel in a run-flat state; the support ring is a non-detachable support ring or a detachable support ring; a non-detachable supporting ring is arranged on the inner side face of the tire tread of the tire, or a connecting part used for being matched with the detachable supporting ring to be connected and fixed is arranged; and the detachable support ring is connected with the connecting part through a zipper or a bindingrope or a bolt so as to be fixed on the tire. When the tire is deflated, the ground contact area of the tread is small, less heat is generated, and the durability of deflated continuation is not influenced; the safety and comfort are not deteriorated, the supporting ring and the tire are easy and convenient to disassemble and assemble, the structure is simple, the comprehensive cost is low, and the automobile tire can be widely applied to common automobiles.

Description

technical field [0001] The invention relates to the field of run-flat tires, and more specifically, the invention relates to a run-flat tire system in which a support ring is arranged on the inner side of the tread. Background technique [0002] Car blowouts can easily cause serious safety accidents. According to the statistics of the American Society of Automotive Engineers (SAE), 70% of the traffic accidents on the expressway are caused by a blowout; and the survival rate of a blowout on the expressway is only less than 5%. A tire blowout on the highway can easily lead to serious accidents such as rear-end collisions, and cause traffic jams; in addition, there are hidden dangers of robbery when changing tires in an unsafe environment. At present, run-flat tires can effectively prevent the occurrence of the above-mentioned accidents, and the sidewall-reinforced run-flat tires represented by the full series assembly of BMW cars are the most common. The sidewall-reinforced ...
