Problems solved by technology

[0005] 1) The spokes are used as support between the damping holes, the strength is relatively low, and it is not conducive to the improvement of tire heat dissipation performance and weight reduction
[0006] 2) There are relatively sharp angles at both ends of the bow-shaped damping hole, which is easy to cause stress concentration, which is not conducive to the improvement of tire life
[0007] 3) When the inner ring is provided with a single anti-slip protrusion in the circumferential direction or axial direction, it can only prevent slipping in one direction; when the circumferential and axial directions are installed at the same time, the process is complicated, and the two sets of anti-slip protrusions interact with each other, affecting the anti-slip effect

Abstract

The invention provides a non-pneumatic safety tire, which comprises a tread, an outer ring, a support body and an inner ring from the outside to the inside in order. The tread is bonded or vulcanized on the outer ring, the support body is arranged between the inner ring and the outer ring along the radial direction and circumferential direction from the outer ring, multiple groups of damping units and support ribs, each group of damping unit consists of two sets of damping structures, and two sets of damping structures are circumferentially disposed with the radial direction as the symmetric axis. The non-pneumatic tire provided by the invention has good bearing capacity, and by means of wheel disk thickening and multiple damping hole diameter change, the bearing capacity of the tire can be enhanced. The non-pneumatic safety tire not only has the carrying capacity and static rigidity characteristics of pneumatic tyres, but also has rationally distributed ground pressure, the abrasion resistance and trip distance of the tire are increased, especially the reasonable distribution of multiple damping holes and support ribs in the radial and circumferential direction can enhance the carrying capacity of the tire and also can improve the static rigidity of the tire.

Description

technical field [0001] The invention relates to a non-inflation safety tire, which is suitable for tires on various vehicles, especially suitable for truck tires, and can improve the bearing capacity and safety of the tires. Background technique [0002] As an important part of modern automobiles, tires have undergone decades of rapid development and have formed multiple series such as pneumatic tires, solid tires, and non-inflatable tires. Pneumatic tires that are widely used at present have disadvantages such as difficult maintenance, air leakage, and tire blowout; although solid tires do not have the problem of air leakage, they are heavy in weight and poor in elasticity, which is not conducive to the improvement of comfort. Due to the advantages of no inflation, puncture resistance, easy maintenance, long life, and easy refurbishment and reuse, non-pneumatic tires are suitable for use on vehicles with harsh working environments. In recent years, more and more attention h...
