Abstract
The invention discloses a tire with improved aging durability. The tire comprises a tire structure, wherein the tire structure comprises a lining layer, a belted layer, a sidewall, a tire bead steel wire and a filling rubber material; the belted layer comprises a first belted layer and a second belted layer, a horizontal width difference value of the first belted layer and the second belted layer is delta 1, and a first reinforcing rubber material and a second reinforcing rubber material are respectively connected to top parts of the first belted layer and the second belted layer and are close to one end of the tire side; design is performed according to the existing requirements, the structural composition is optimized by adjusting the structure design of different components, the width of the belted layer, the width and the thickness of the belted layer reinforcing material, the width and the thickness of the lining layer, the rubber material used in the specific area of the lining layer, and the thickness and the width of the sidewall reinforcing material are reasonably combined so that the tire has strong ageing resistance, the tire manufactured according to the invention has improved anti-aging durability, and the tire can smoothly pass a strict indoor aging durability experiment.
Description
technical field [0001] The invention relates to the technical field of tire production, in particular to a tire with improved aging durability. Background technique [0002] Tires in the prior art are used under special weather conditions and operating conditions, which will accelerate the aging of the tires. Through the simulation test of indoor aging durability, the anti-aging ability of tires can be predicted to provide guarantee for safe use. Conventionally designed tires can successfully pass the durability requirements of conventional regulations, but are prone to failure for more stringent aging durability. The most common failure modes are shoulder cracks, delamination, crown delamination, bead cracks, delamination, and puncture. [0003] The existing patent notification number is CN 107415591 B, which is a pneumatic radial tire with improved durability performance. By adding belt edge rubber, positive wrap structure and sidewall adhesive reinforcing strip structur...
