Damping run stability control based on sidewall elastic mechanism

[0063] Example 1

[0064] A shock-absorbing run-flat tire based on the sidewall elastic mechanism of this embodiment, such as figure 1 shown, including,

[0065] carcass 1;

[0066] Also includes,

[0067] The elastic mechanism 2 is composed of a concave structure annularly disposed on the sidewall, and the cross-sectional shape of the concave structure along the radial direction of the carcass 1 is arc-shaped.

[0068] After analysis, in actual production and use, the traditional hollow-hole structure tires have the following disadvantages:

[0069] 1) In the production process of the non-inflated solid tire with through holes, it is easy to be damaged during the process of taking out the hollow mold, resulting in a high defective rate;

[0070] 2) During the long-term riding process, water or impurities are easy to accumulate inside the through hole, and it is easy to cause danger when suddenly thrown out. In winter, the freezing in the hole cavity will cause the weakening

[0079] Example 2

[0080] A shock-absorbing run-flat tire based on the sidewall elastic mechanism of this embodiment is further improved on the basis of Embodiment 1, such as figure 2 and image 3 As shown, the elastic mechanism 2 is constituted by a hemispherical cavity 20 annularly arranged along the sidewall.

[0081] In the shock-absorbing and explosion-proof tire based on the sidewall elastic mechanism of this embodiment, the concave structure in the elastic mechanism 2 is a semi-balloon cavity 20, and the semi-balloon cavity 20 is a semi-spherical concave cavity. According to the structural design of the embodiment, when any point on the hemispherical cavity 20 receives the transmitted impact force, the spherical structure can transmit the force evenly in all directions, and finally transmit the force along the spherical surface to the sidewall to be released. , which ensures the stability of the vehicle when it encounters bumps. This performance can greatly increase the

[0082] Example 3

[0083] A shock-absorbing run-flat tire based on the sidewall elastic mechanism of the present embodiment is further improved on the basis of the first and second embodiments, and the elastic mechanism 2 is composed of a semi-ellipsoid cavity 200 annularly arranged along the sidewall.

[0084] The semi-ellipsoid cavity 200 is an evolution of the semi-ellipsoid cavity 20, which includes the advantages of the above-mentioned hemispherical cavity structure. The semi-ellipsoid cavity 200 in this embodiment can be set in three ways:

[0085] a. The long axis of the semi-ellipsoid is arranged along the circumferential direction of the carcass 1, such as Figure 12 , Figure 13 and Figure 14 As shown, when the semi-ellipsoid cavity 200 is subjected to a large impact force, that is, when the degree of deformation is large, the excess impact force can spread along both ends of the long axis. The durability of the ellipsoid cavity 200 is higher than that of the hemisp
