Truck radial tire with full-contact steel wire ring and winding disc of truck radial tire

Abstract

The invention discloses a truck radial tire with a full-contact steel wire ring. The truck radial tire comprises a tread, a belted layer, tire shoulder pad rubber, a sidewall, upper apex, nylon wrapping cloth, a tire body, steel wire wrapping cloth, lower apex, seam allowance wear-resistant rubber, a lining layer and the steel wire ring. The invention further provides a winding disc of the truck radial tire with the full-contact type steel wire ring. According to the steel wire ring composed of the regular hexagonal tire bead steel wires, the left face and the right face of each regular hexagonal tire bead steel wire are automatically vertical faces through the triangular sawtooth faces of the corresponding winding discs of the steel wire ring, and therefore it is guaranteed that the six faces of the regular hexagonal tire bead steel wires are attached to one another to form a face contact stable structure with a self-locking function; no gap exists between the steel wires, it is guaranteed that no residual air exists in the wound steel wire ring, the early-stage damage problems such as ring empty, three-wire cracks, seam allowance burning and wire drawing explosion caused by too high heat generation of the tire bead under the heavy load condition of a vehicle are avoided, and powerful guarantee is provided for long-term durability and safe driving of the tire.

Description

technical field

[0001] The invention relates to the technical field of all-steel wire radial truck tires, in particular to a radial truck tire with a full-contact bead ring and a winding disc thereof. Background technique

[0002] With the rapid growth of China's economy, traffic roads and vehicles have also achieved rapid growth, so the quality requirements for tires assembled on trucks and buses are also getting higher and higher. It has been more than 30 years since China introduced the technology of all-steel radial truck tires, and great achievements have been made through digestion and absorption and technological innovation. The shape factor is very easy to loose the ring, and the strength of the loose ring cannot meet the design requirements, which will easily cause the tightening force between the tire and the rim to weaken and the locking force of the bead to lock the carcass steel wire. As a result, the tire is prone to creep and friction on the rim, and the stre...
