Problems solved by technology

[0003] The hydraulic burst test is an important test to test the safety of tires. In domestic tire companies, the tire bead wire is mostly formed by root-row winding. The biggest disadvantage of this winding method is that the utilization rate of the wire breaking force is low. Only 50% of the breaking force of the steel wire, resulting in waste of materials, and the tire's anti-burst ability is low

Embodiment Construction

[0014] The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

[0015] like figure 1 As shown, this embodiment includes a tread 1, an inner liner 2, a carcass layer 3 and a bead 4, the inner liner 2 is arched, the carcass layer 3 is wrapped outside the inner liner 2, and the bead 4 is a single steel wire Made by winding, the tread 1 is located on the top of the carcass layer 3; the carcass layer 3 is made of polyester cords, and the ratio of crown width to section width of the tire is 110-120%. The arch in this embodiment is composed of three arcs, and the radius ratio of the three arcs is 20:4:3.

[0016] The single steel wire winding technology greatly reduces the number of...

Abstract

The invention discloses a single-wire twining off-the-road type rainforest tyre. The tyre comprises a tread, a lining, a cord fabric layer and a tyre bead, wherein the lining is in an arched shape, the cord fabric layer covers the outside of the lining, the tyre bead is made by twining of a single wire, the tread is located at the top of the cord fabric layer, the cord fabric layer is made of polyester cord threads, and the ratio of the crown width of the tyre to the section width of the tyre is in a range of 110%-120%. The inner outline of the tyre looks like an arch bridge, so that the stress can be uniformly distributed to all positions of the tyre, and the deformation probability of the tyre is reduced. The ratio of the crown width to the section width is high, so that the large grounding area and the high road holding force of the tyre can be achieved. The crown width is widened, and the unidirectional inflated tyre tooth design is adopted on two sides of the tread, so that the tyre is provided with the excellent road holding force and the excellent driving force in rainforest landforms; and by the aid of the design that the side wall is narrow, the tread is wide and tyre teeth are inflated, the tyre side wall can be protected, and the side wall is prevented from being cut or punctured by sharp stones.

Description

technical field [0001] The invention relates to an off-road rainforest tire, in particular to a single steel wire winding off-road rainforest tire. Background technique [0002] With the development of the economy, people's living standards are gradually improving, off-road sports will be loved by more and more people, off-road tires will become the mainstream, tires are safety parts on cars, and the safety of tires will be particularly important. How to improve tires The security of the company will become an important issue for the company. [0003] The hydraulic burst test is an important test to test the safety of tires. In domestic tire companies, the tire bead wire is mostly formed by root-row winding. The biggest disadvantage of this winding method is that the utilization rate of the wire breaking force is low. Only 50% of the breaking force of the steel wire, resulting in waste of materials, and the tire's anti-burst ability is low. Contents of the invention [0...
