Problems solved by technology
However, while the new non-pneumatic tires provide these conveniences, they also have the disadvantages of poor shock absorption, load bearing, and heat dissipation. Therefore, the new non-pneumatic tires have not been widely used. Major companies and universities are starting to study, hoping to propose a solution as soon as possible. High-performance non-pneumatic tires for popular use

Embodiment Construction
[0021] The present invention proposes a soft-spoke non-pneumatic tire with high cushioning and shock-absorbing performance. Using the principle of "curved surface", the side webs of the flexible spokes are designed as wavy lines composed of three arcs with a certain curvature.
[0022] The utility model includes from the outside to the inside sequentially: a tire crown 1, a flexible spoke 2 made of polyurethane material, and a rigid rim 3. The crown 1 includes a tread 1-1, a cap layer 1-2, a No. 1 belt layer 1-3, and a No. 2 belt layer 1-4; the tread 1-1 includes a tread pattern 1- 1a, tread pattern groove 1-1b; the flexible spoke 2 includes a soft-spoke inner ring 2-1, a soft-spoke outer ring 2-2, a soft-spoke side spoke plate 2-3, and a soft-spoke peripheral spoke plate 2-4.
[0023] The soft spoke side spoke plate 2-3 is set in a wavy line shape composed of three sections of arcs with a certain curvature, and the three sections of arcs can be set to be equal curvature, or c...

The invention relates to a flexible spoke type non-pneumatic tire with high buffering and damping performance, and belongs to the field of tires. The non-pneumatic tire comprises a tire crown, a flexible spoke made of a polyurethane material and a rigid rim from outside to inside. The tire crown comprises a tire tread, a crown belt layer, a first belt ply and a second belt ply; the tread comprisestread patterns and tread pattern grooves; the flexible spoke comprises a flexible spoke inner ring, a flexible spoke outer ring, a flexible spoke side spoke plate and a flexible spoke peripheral spoke plate; the flexible spoke side spoke plate is configured into a wavy line shape; the flexible spoke circumferential spoke plate is arranged to be of a layered structure; chamfers are arranged at thesharp corners of the peripheral and side radial plates, the bearing capacity of an automobile can be greatly improved, and vibration generated by the automobile relative to the road surface in the driving process is efficiently absorbed so that the driving safety and riding comfort are improved, stress concentration is reduced, the fatigue life is prolonged, the rim is connected with a half shaftof the automobile, the non-pneumatic tire is in interference fit from inside to outside, and the structure is compact.
Description
technical field [0001] The invention relates to the field of tires, in particular to a non-pneumatic tire, in particular to a soft-spoke non-pneumatic tire with high cushioning and shock-absorbing performance. Background technique [0002] As we all know, with the development of the times and the popularization of automobiles, the defects of automobile pneumatic tires are gradually revealed: easy to blow out tires, easy to cause catastrophic losses after blowing out tires, tire pressure needs constant maintenance, and the manufacturing process is cumbersome. In recent years, pneumatic tires, which have dominated the world tire market for more than 100 years, have been gradually replaced by emerging non-pneumatic tires. Compared with pneumatic tires, the main and most direct advantage of non-pneumatic tires is that there will be no tire blowout, and its production process is simple, avoiding cumbersome production processes. Generally speaking, non-pneumatic tires break some ...
