Abstract

The invention mainly provides a tire with a tire bead structure, which comprises an annular tire body, a tire tread and two tire beads respectively extending from two sides of the tire tread, and the preset part of each tire bead is provided with an annular concave groove part; convex pieces which are arranged in the groove parts at preset intervals in an annular arrangement mode, and the convex pieces protrude by a certain height from the bottom edges of the groove parts; by means of the components, by means of the structural design of the rib-shaped protruding pieces formed on the tire bead, blade rotation can be generated to bounce off and break off long foreign matter, in cooperation with the design of the quite-hollowed-out groove part, foreign matter puncture can be effectively avoided, the probability that the tire bead is punctured is reduced, the puncture-proof effect is improved, and under the condition that wind pressure is insufficient or the tire bead is impacted, the supporting performance of the tire can be maintained. The structural design of the groove parts and the rib-shaped convex pieces of the tire bead does not increase the overall weight of the tire.

Description

technical field

[0001] The present invention relates to the bead structure of tires, in particular, there are several ring-shaped protruding parts on both sides of the bead of the tire, so that the bead can prevent side impact, prevent puncture, remove foreign objects and increase support force. Background technique

[0002] Vehicles running on the road, whether they are automobiles, locomotives or bicycles, mostly use the rolling of the wheels to move forward, backward or turn, and the tires of the wheels are directly in contact with the ground for rolling. Because tires must absorb the impact from the ground when rolling, rubber with elasticity and cushioning properties is used in the material to effectively improve driving comfort; in addition, tires also have considerable requirements for support. To bear the gravity of the sum of the upper car body, passengers and articles.

[0003] The tire structure generally includes tread, bead, bead and carcass. The bead is locate...

Embodiment Construction

[0041] First please refer to Figure 1 to Figure 5 , A tire 10 with a bead structure provided by the present invention includes: a carcass 11 , a tread 12 , two bead 13 , and several protrusions 20 arranged on the two bead 13 .

[0042]The tire 10 has a tread 12 and two sidewalls 13 respectively extending from both sides of the tread 12, and a shoulder 17 is formed between each tread 12 and the sidewalls 13; each sidewall 13 is preset Each part has a groove part 14 which is recessed in a ring shape; the bead 13 has a ring-shaped rim line 15 respectively, and its outermost ring part is set as a first reference line D; the broken width of the tire 10 is Set as SW; the center line of the tire is set as CL, respectively set as a left reference line 161 and a right reference line 162 at the positions of 1 / 3 SW width on the left and right sides of the center line CL; the left reference line 161 When the right reference line 162 intersects with the bottom of the tread 12, there are ...
