Problems solved by technology
There are certain defects in the above forms: 1. The carcass 1 and the steel ring 3 are mainly made of steel wire. Under high load pressure, the rigid impact between the two is more obvious, and the steel wire breaks when it is serious; 2. The prior art The shape of the middle steel ring 3 is generally a rectangle, a hexagon and other polygons, and stress concentration is prone to occur at its corners, and the impact between the steel wires is more serious.

Embodiment Construction
[0013] The present invention will be further described below in conjunction with the embodiments in the accompanying drawings:
[0014] like figure 2 As shown, the present invention mainly includes a carcass 1, the carcass 1 includes a carcass main part 1.1 and a carcass turn-up part 1.2, and the carcass 1 is covered with a steel ring 3 and an apex 4. The steel ring 3 is located at one end of the turn-up portion 1.2 of the carcass, and the apex 4 is connected to one end of the steel ring 3 .
[0015] The outer surface of the steel ring 3 is covered with a steel ring wrapping film 5. The steel ring wrapping film 5 not only protects the steel ring 3 and the carcass 1, but also acts as a buffer between the steel ring 3 and the carcass 1. , thereby improving the bearing capacity and service life of the bead. The steel ring wrapping film 5 is made of rubber material.
[0016] The outer surface of the carcass 1 is covered with a bead reinforcement layer 2 , and the strength of t...

The invention relates to a tire bead structure, especially relates to a tire bead structure adopting a film to wrap a steel ring, and belongs to the technical field of tires. The tire bead structure comprises a tire body, the tire body comprises tire body main part and a tire body anti-packaging part, and the steel ring and a triangular binding bar are coated in the tire body. The steel ring is positioned at one end of the tire body anti-package part, the triangular binding bar is connected to one end of the steel ring, and the external surface of the steel ring is coated with a steel ring wrapping film. The tire bead structure is simple, compact and reasonable, solves a phenomenon of rigid impact and stress concentration between the steel ring and the tire body, and improves the bearing capability and the service life of the tire.
Description
technical field [0001] The invention relates to a tire bead structure, in particular to a tire bead structure using a film to wrap a steel ring, and belongs to the technical field of tires. Background technique [0002] Existing wheeled vehicles, especially large freight trucks, which run on the highway, not only require higher speed but also better bearing capacity. high demands. The key points of the quality of the tire bead are mainly two parts: the first is the bead structure of the tire, and the second is the selection of the tire bead material. Especially the tire bead structure, the reasonable design of the tire bead structure can significantly enhance the bearing capacity of the tire, increase the service life of the tire, and achieve high-efficiency transportation operations for multi-pulling and fast running. [0003] At present, the tire bead structure in various tire enterprises is generally composed of the following parts: carcass 1, bead reinforcement layer 2...
