Problems solved by technology

When traditional pneumatic tires are subject to high impact (for example, when a vehicle is thrown in the air under special circumstances, the acceleration of gravity of the impact force can increase by 6 to 7 times), there may be a risk of tire blowout. Non-pneumatic tires on the market generally do not carry high loads. , it will even be distorted when subjected to high impact, which is not conducive to the transportation of vehicles under special circumstances

Embodiment Construction

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] The invention provides a pseudo-rigid non-inflatable tire imitating the rear leg structure of a quadruped, such as figure 1 and figure 2 As shown, the pseudo-rigid non-pneumatic tire includes a wheel hub 2 and a wheel 3, the wheel 3 is arranged on the outer ring of the wheel hub 2, the two are arranged concentrically, the diameter of the wheel 3 is larger than the wheel hub 2, and the diameter of the wheel 3 is generally 1.5-3 times of hub 2, such as Figure 5 As shown, the wheel 3 is made up of a skeleton 31 and a rubber 32 wrapped on the surface of the skeleton. The skeleton of the wheel hub 2 and the wheel 3 is made of metal materials, such as stainless steel, manganese steel, silicon steel, etc., ...

Abstract

The invention, which belongs to the technical field of non-pneumatic tires, discloses a pseudo-rigid non-pneumatic tire imitating a quadruped rear leg structure. The pseudo-rigid non-pneumatic tire comprises a hub and a rim; a plurality of plate springs are arranged between the hub and the rim; arc-shaped bends are arranged in the middles of the plate springs; all the plate springs are evenly distributed between the hub and the rim in the circumferential direction; one end of each of the plate springs is connected to the surface of the outer ring of the hub, and the other ends of the plate springs are connected to the surface of the inner side of the rim. The plate springs imitating quadruped rear leg structures and a rim are used as buffering and damping structures. The pseudo-rigid non-pneumatic tire has the congenital advantages of high bearing capacity and impact resistance; the characteristic that the rear legs of the quadruped can bear the large impact when the quadruped runs isutilized, the plate spring structure imitating the rear legs of the quadruped can also bear the large impact force; the radial rigidity of the plate spring structure is large; and thus the pseudo-rigid non-pneumatic tire is suitable for working in the environment with high bearing capacity and high impact.

Description

technical field [0001] The invention belongs to the field of air-free safety tire technology and bionic technology, and in particular relates to a pseudo-rigid air-free tire imitating the rear leg structure of a quadruped. Background technique [0002] Traditional pneumatic wheels use rubber to wrap air and use tire pressure as the main load-bearing method. Most non-pneumatic tires on the market also use special rubber materials to carry heavy loads under special shape structures. When traditional pneumatic tires are subject to high impact (for example, when a vehicle is thrown in the air under special circumstances, the acceleration of gravity of the impact force can increase by 6 to 7 times), there may be a risk of tire blowout. Non-pneumatic tires on the market generally do not carry high loads. , It will even be distorted when subjected to high impact, which is not conducive to the transportation of vehicles under special circumstances.
