Abstract
Description
A wear-resistant tire with uniform stress distribution Technical Field
[0001] This utility model relates to the field of tire technology, and in particular to a wear-resistant tire with uniform stress distribution. Background Technology
[0002] Tires are annular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. They are typically mounted on metal rims, supporting the vehicle body, cushioning external impacts, ensuring contact with the road surface, and guaranteeing vehicle performance. The structural design of the tire tread is crucial to its performance characteristics. For example, "a wear-resistant tire with publication number CN211764715U includes a tire rubber outer layer and a carcass reinforcement layer. The tire rubber outer layer consists of a tread, sidewall, and bead. The carcass reinforcement layer is located on the inner surface of the tire rubber outer layer. A crown is located in the middle of the upper surface of the tread, and shoulders are located on both sides of the crown. The carcass reinforcement layer includes a tread base rubber, a crown protection layer, a crown belt layer, and a braided layer." The tread base rubber is fixedly connected to the upper surface of the crown protection layer, the crown protection layer is fixedly connected to the upper surface of the crown belt layer, and the crown belt layer is fixedly connected to the upper surface of the braided layer. This effectively improves the tire's wear resistance, increases its adhesion to the ground, effectively enhances its heat dissipation and water drainage performance, and better ensures that the tire body is not easily punctured by hard objects, effectively preventing tire blowouts and better ensuring driving safety. However, during vehicle operation, various bumpy roads are frequently encountered, causing uneven stress on different parts of the tire. This uneven stress concentration and excessive local stress can severely damage the tire and shorten its lifespan. Summary of the Invention
