Problems solved by technology

[0009] However, in terms of the former, the neck formed by the base is actually more likely to allow stones to enter and be stuck in the neck with a smaller outer diameter, and it is less likely to achieve the effect of self-expelling stones; the latter structure is When the tire wears down to the platform, the overall groove will become narrower, and the volume of the water supply flow in the groove will be greatly reduced, and the drainage will also be greatly reduced, which will easily cause the tire to slip during driving.

Embodiment Construction

[0034] First please refer to Figure 1 to Figure 4 , the anti-stone structure of a tire groove provided by the present invention is set on a tread 50 in a default quantity, which includes: a tire groove 10, and a tire groove in the groove 10 Convex step group 20.

[0035] The sipe 10 is an open groove with a groove bottom 11 and two side edge walls extending to a preset height, and the two side edge walls are a first side wall 12 and a first side wall with a preset slope respectively Two sidewalls 13; the slopes of the first sidewall 12 and the second sidewall 13 are different, the edgewall near the center of the tire tread 50 is the first sidewall 12, and the edgewall near the shoulder The edge wall of 40 is the second sidewall 13 ; the inclination angle between the first sidewall 12 and the trench bottom 11 is larger than the inclination angle between the second sidewall 13 and the trench bottom 11 .

[0036]The convex step group 20 is arranged in the sipe 10, and has a fi...

Abstract

The invention provides a structure for preventing stone from being clamped in a tire slot. A preset amount of such structures are arranged on a tread; the structure comprises a patterned tire slot and a convex step group; edge walls at two sides of the tire tread slot are respectively set to be a first side wall with a preset inclination and a second side wall with a preset inclination, and the inclinations of the edge walls of the first side wall and the second side wall are different; and the convex step group is arranged in the patterned tire slot and provided with a first convex step with a preset height and a second convex step with a preset height respectively on the first side wall and the second side wall; the first convex step and the second convex step are respectively provided with a curved surface convexly extending at a preset curvature and are continuous along the first side wall and the second side wall; and therefore, through the matching of the first side wall and the second side wall which have different inclinations and are arranged at two sides as well as the first convex step and the second convex step which have different curvatures of the curved surfaces and are arranged on the first side wall and the second side wall, small broken stone is not easy to clamp when the stone enters the slot, and then, the effect of preventing the stone from being clamped is achieved; meanwhile, the situation of turbulent flow is reduced, so that better drainage performance is achieved, the stone is easier to automatically discharge, the service life of a tire is prolonged, and the safety of the tire is improved.

Description

technical field [0001] The present invention relates to tire tread pattern groove structure, especially the anti-stone trapping structure of tire tread groove. Background technique [0002] Most vehicles use the rolling of the wheels to make the car body move forward or backward, and the tire is the medium between the ground and the rim, which uses the shock-absorbing properties of plastic materials to make the car body move forward The middle can buffer the impact force from the ground and improve the ride comfort. [0003] The carcass of the tire needs to be supportive. It is used to embed components such as high-strength plies, belts, or metal belts in the carcass. The ply is mostly made of glass fiber or polyamide fiber; the tread of the tire is added. There are several tread patterns to increase drainage and grip, and even reduce noise. [0004] Recently, the technology of tires has developed towards the function of anti-rock, mainly to solve the problem of small grav...
