Drift tire with excellent road holding and controllability and manufacturing method thereof

Abstract

The invention discloses a drift tire with excellent road holding and controllability and a manufacturing method thereof. A tire tread is on a cross section of a tire meridian line; a profile from an intersection point of a tire equatorial plane and a tire tread profile to a tire tread end of a tire shoulder part is formed by sequentially connecting four sections of arcs and a tire shoulder arc; and the four sections of arcs are sequentially connected and are finally connected with the tire shoulder arc. According to the drift tire with excellent road holding and controllability and the manufacturing method thereof provided by the invention, the saturability of the outer side of a tread pattern is larger than the saturability of the inner side, and a pattern groove adopts a chamfer design;a tire structure is characterized by adding steel wire reinforcement for STEEL on the outer side of a triangle adhesive + adding aramid fiber reinforcement for the outer side of a No.1 tire body on the inner side of the triangle adhesive; high-technology materials such as aramid fiber is added for matching with steel wire cords, so that the hardness of a tire wall is reinforced, meanwhile, the dead weight is reduced, and the supportability of the tire is improved; with the profile design of the four sections of arcs and the tire shoulder arc, the uniform ground contact pressure and a wider netcontact surface can be obtained, and the grounding marks and the ground contact pressure distribution of the tire are favorably optimized; and the tire provided by the invention has excellent road holding and controllability and has high breaking strength.

Description

technical field [0001] The invention belongs to the technical field of rubber, and in particular relates to the profile design, pattern design, construction design and manufacturing method of drifting tires, in particular to a drifting tire with excellent grip and controllability and a manufacturing method thereof. Background technique [0002] Drift tires are derived from ordinary UHP series tires. The difference from ordinary UHP series products is that drift tires require the tread of the tire to have stronger grip, and the carcass has sufficient rigidity under low air pressure conditions to ensure the control of the tire. sex. [0003] Like F1 and WRC, D1 Drift Grand Prix is ​​one of the few world-class professional events certified by FIA (International Automobile Federation). 2016 is a milestone for China's car drifting, because it has been developed in Japan for 16 years, and the world's top drifting event known as "F1" in the drifting world - Japan's D1 GRAND PRIX o...

AI Technical Summary

Problems solved by technology

By changing the tread profile arc and defining the functional relationship of a, b, c, d, e and h1, h2, the design of the tire tread profile shape can be realized to improve the deformation of the tire when it touches the ground and the drainage capacity of the tire during driving , optimize the wet drainage performance of the tire, and improve the safety of driving in rainy days; but in the current technology, some drift tire products only add STEEL steel wire reinforcement on the outside of the apex rubber, and some only add STEEL steel wire reinforcement on the outside of the sidewall carcass , some are reinforced with STEEL steel wire on the outside of the apex + blended reinforcement on the outside of the carcass outside the apex, some have no reinforcement on the apex and sidewall, the grooves are not chamfered, and the carcass does not work under low pressure conditions. There is enough rigidity to ensure the handling of the tire
