Structure for preventing stone from being clamped in tire slot

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...
