Abstract

The invention discloses a tire capable of protecting a bead against internal cracking and belongs to the technical field of tires. The tire comprises the bead, the bead comprises a steel wire ring, a tire body cord fabric layer and heel fabric, and the tire body cord fabric layer winds across the bottom of the steel wire ring. The heel fabric comprises a first-section heel fabric body and a second-section heel fabric body which are attached to the tire body cord fabric layer. The first-section heel fabric body is located on the side, close to the steel wire ring, of the tire body cord fabric layer, the second-section heel fabric body is located on the side, away from the steel wire ring, of the tire body cord fabric layer and winds across the bottom of the steel wire ring, and the upper end point of the first-section heel fabric body is located on the upper side of the internal end point of the second-section heel fabric body. According to the tire capable of protecting the bead against internal cracking, the problem of stress concentration of the internal end point of the heel fabric is solved, so that performance of the bead portion is improved, and the service life of the tire is prolonged.

Description

technical field [0001] The invention belongs to the technical field of tires, and in particular relates to a tire for preventing internal cracking. Background technique [0002] The bead, also known as the tire bead, refers to the part where the tire is installed on the rim. It is composed of a steel wire ring and a bead wrapping cloth. Suffering from the lateral force, the tire will not escape from the rim, so it must have high strength and is not easy to deform. [0003] However, in the process of using tires, users often do not choose standard rims, choose small rims or choose rim edges that are not standard, or use overload and low air pressure during loading, resulting in large deformation of the tire rim, making the rim The stress at the inner end of the cloth increases, and internal cracking occurs, which leads to early damage to the tire, affects the life of the tire, and leads to a great safety hazard. Contents of the invention [0004] The technical problem to ...
