Problems solved by technology
However, the bead structure of ordinary tubeless tires usually adopts a layer of steel wire wrapped cloth structure. Under heavy load conditions, the tire sink rate is large, the stress on the bead is easy to concentrate, and the tire's load-bearing performance is poor, resulting in early damage to the bead. , unable to meet the use requirements of large-tonnage heavy-duty vehicles

The invention provides a tire bead part for improving the bearing performance of a tubeless tire. The tire bead part comprises a tire bead, filling rubber, a turn-up tire body, a transition rubber sheet group, a nylon wrapping cloth group, seam allowance wrapping rubber, seam allowance wear-resistant rubber and tire side rubber, wherein the tire bead is arranged in the turn-up tire body; filling rubber is arranged above the tire bead between the tire body and the turn-up tire body; the seam allowance wrapping rubber is coated at a seam allowance joint part between the filling rubber and the turn-up tire body; the lower part of the seam allowance wrapping rubber is coated with the seam allowance wear-resistant rubber; the sidewall rubber is wrapped along the outer sides of the bead rubber coating and the bead wear-resistant rubber; the transition rubber sheet group is attached between the filling rubber and the turn-up tire body. According to the scheme, a steel wire reinforcing layer at the tire bead part is canceled and replaced by the nylon wrapping cloth layer, so that the aims of reducing the rigidity of the tire bead part, reducing the stress strain at the end point part of the steel wire and increasing the effective bending and fishing area of the tire are fulfilled.
Description
technical field [0001] The invention relates to the technical field of tire preparation, in particular to a bead portion for improving the bearing performance of a tubeless tire. Background technique [0002] my country's road transportation environment is complex, and some areas are seriously overloaded. The vehicles used in overloaded areas are generally heavy-duty vehicles. The tires used by heavy-duty vehicles are inner tube tires. In recent years, with the change of my country's road transportation environment, the transportation vehicles are also constantly changing, and the tires used are gradually changing from tubeless tires to tubeless tires. However, the bead structure of ordinary tubeless tires usually adopts a layer of steel wire wrapped cloth structure. Under heavy load conditions, the tire sink rate is large, the stress on the bead is easy to concentrate, and the tire's load-bearing performance is poor, resulting in early damage to the bead. , unable to meet ...
