Embodiment 1

[0031] See Figure 1 to Figure 4 , In one embodiment, an elastic non-pneumatic tire includes a hub 5, a bead 4, and a carcass.

[0032] The outer bead 4 is sleeved on the hub 5 and cooperates with the hub 5 to form a ring-shaped space.

[0033] The carcass includes several carcass components. The carcass components are respectively arranged in the ring arranging space, and both ends of each carcass component are connected with the outer circumferential surface of the hub 5 and the inner circumferential surface of the outer bead 4 respectively.

[0034] Wherein, the carcass component includes an annular elastic member 1 and a first elastic unit 2. The first end of the annular elastic member 1 is connected with the inner circumferential surface of the outer bead 4, the second end is connected with the outer circumferential surface of the hub 5, and the opening of the annular elastic member 1 faces the circumferential direction of the hub 5. The first elastic unit 2 is provided in the...

Embodiment 2

[0044] A vehicle is equipped with the elastic non-pneumatic tire in the first embodiment. The elastic non-pneumatic tire is provided with a hub 5, an outer bead 4 and a carcass. The carcass is arranged between the hub 5 and the outer bead 4; wherein the carcass specifically includes an annular elastic member 1 and a first elastic unit 2. The annular elastic member 1 is arranged between the hub 5 and the outer bead 4, and the first elastic unit 2 is arranged in the inner ring of the annular elastic member 1 to support the annular elastic member 1. The annular elastic member 1 forms the overall external configuration of the tire and Provide a certain supporting force at the shoulder portion, the annular configuration ensures the radial and lateral mechanical properties of the tire, the first elastic unit 2 supports the tread to improve the radial rigidity of the tire, the annular elastic member 1 and the first elastic unit 2 The elastic characteristics of the tires make the tires...

Abstract

The invention discloses an elastic non-pneumatic tire and a vehicle. Through arranging a hub, an outer tire ring and a tire body, the tire body is arranged between the hub and the outer tire ring; thetire body specifically comprises an annular elastic piece and a first elastic unit; the annular elastic piece is arranged between the hub and the outer tire ring; the first elastic unit is arranged in the inner ring of the annular elastic piece for supporting the annular elastic piece; the annular elastic piece forms an integral external configuration of the tire and provides a certain supportingforce at the tire shoulder part; the radial and lateral mechanical properties of the tire are guaranteed through the annular configuration; the first elastic unit supports the tread to improve the radial rigidity of the tire; the tire has a certain damping effect through the elastic characteristics of the annular elastic piece and the first elastic unit; and the problem that an existing elastic tire is poor in radial and lateral mechanical properties is solved.

Description

Technical field [0001] The invention belongs to the technical field of tires, and particularly relates to an elastic non-pneumatic tire and a vehicle. Background technique [0002] Wheels are used for grounding rolling on various vehicles or machinery to achieve contact with the road and ensure the driving performance of the vehicle. Traditional wheels generally use pneumatic tires, but pneumatic tires need to be inflated frequently and there is a risk of puncture. At present, R&D and design teams in the United States, Europe and Japan have proposed many configurations of non-pneumatic tires. Compared with ordinary tires, non-pneumatic tires have the advantages of maintenance-free, puncture-free, and leakage-free. [0003] The current internal structure strengthening methods of elastic tires are mainly constant cross-section type and circumferential rotation array type, and they are all open structure designs, which have disadvantages such as weak radial and lateral rigidity and l...
