AI Technical Summary
Technical Problem
Traditional metal belt layers are heavy, have high friction, and generate significant heat, which can lead to quality problems such as shoulder gaps after long-term high-speed driving. In addition, the manufacturing process is complex.
Method used
It adopts a lightweight woven belt layer structure, with metal steel wires intersecting to form a triangular grid. The surface is coated with a nano-coating and an impregnated coating. There are micro gaps between the steel wires to enhance the bonding area and adhesion with rubber. It is protected with a phenolic resin composite material.
Benefits of technology
Improve tire structural strength and stability, reduce heat loss and brittle fracture, enhance safety and lifespan, and simplify production processes.

Abstract
The utility model discloses a light woven belted layer for a tire, which relates to the technical field of tire design and manufacture, and comprises a tread, a netted woven belted layer, a tire body and a plurality of metal steel wires, the netted woven belted layer is arranged below the tread, the tire body is arranged below the netted woven belted layer, and the metal steel wires are arranged below the netted woven belted layer. The metal steel wires are arranged in the net-shaped woven belt ply, and micro gaps are formed among the multiple metal steel wires. By arranging the braid belted layer, the overall structural strength and stability of the tire can be effectively enhanced, the bonding force between the belted layer and rubber is improved, the metal steel wires are arranged to be of a triangular net-shaped structure, loads and stress can be evenly dispersed, local fracture or deformation caused by stress concentration is avoided, and the service life of the tire is prolonged. The effective area combined with rubber is increased, and heat loss generated after continuous friction between metal monofilaments under a certain load is reduced.
