Embodiment Construction

[0026] The invention provides a run-flat tire, which is used to solve the problem that the sidewall support rubber of the run-flat tire tends to generate strong heat under the condition of zero air pressure, and the anti-fatigue performance is weakened after driving for a certain distance, and then loses the rubber properties. And ultimately the problem of damage.

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0028] see Figure 1 to Figure 3 , are respectively the structural schematic diagram of the run-flat tire in the prior art at zero air pressure, the structural schemati...

Abstract

The invention belongs to the field of tires, and particularly relates to a run-flat tire. The invention provides the run-flat tire, which comprises a tire body layer, a tire surface layer, a belt bundle layer, an inner lining layer, tire side layers, tire ring cores and a crown belt layer, wherein the pair of tire side layers are connected with the two sides of the tire surface layer; the tire side layers and the tire ring core are connected; the tire body layer is in an annular extending state between the pair of tire ring cores; the tire ring cores are arranged at the tire ring parts; tire side support rubber is arranged between the inner lining layer and the tire body layer in the tire side position; the belt bundle layer, the crown belt layer and the tire surface layer are sequentiallyarranged at the radial outer side of the tire crown part of the tire body layer; a tire crown reinforcing layer is arranged between the belt bundle layer and the crown belt layer.

Description

technical field [0001] The invention belongs to the field of tires, in particular to a run-flat tire. Background technique [0002] Radial tires are non-run-flat tires. When there is serious trauma or puncture on the tread or sidewall of the radial tire, the radial tire will leak and cannot run normally. The run-flat tire can still carry the weight of the car for a certain distance under zero air pressure by adding a certain thickness of support rubber at the sidewall. However, the sidewall support rubber of run-flat tires will generate strong heat under zero air pressure conditions, and the anti-fatigue performance will weaken after driving for a certain distance, and then lose the properties of the rubber compound and eventually be damaged. Contents of the invention [0003] The invention provides a run-flat tire, which is used to solve the problem that the sidewall support rubber of the run-flat tire tends to generate strong heat under the condition of zero air pressur...
