Problems solved by technology

Because the tread rubber of the driving wheel tire is very thick and the pattern groove is very deep, if the base rubber of the tread is thickened, the height of the base rubber is easily higher than the thickness of the bottom of the groove, and cracks at the bottom of the groove are likely to occur during the use of the finished tire. If the base rubber of the tread is thin, the overall thickness of the base rubber at the tire shoulder will be too thin. During the use of the finished tire, the shoulder heat will be too high, and early problems such as shoulder voids will easily occur, shortening the tire service life

Embodiment Construction

[0016] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0017] Such as Figure 1-4 Shown: a tire tread structure suitable for driving wheels, including a tread rubber part 1 and a tread base rubber part 2, characterized in that: the tread rubber part 1 and the tread base rubber part 2 are in The shoulder portion 3 adopts a triangular transition, the base rubber 2 is in continuous contact with the tread rubber 1, and has a concave structure in the middle.

[0018] As an improvement to the above technical solution, the shoulder thickness h2 of the shoulder portion 3 is not higher than one-half of the average thickness of the entire tread, and the thickness h3 of the middle concave part is not higher than one-third of the average thickness of the entire tread.

[0019] As an improvement to the above technical solution, the vulcanized highest point a of the tread base rubber part 2 at the triangular transition part is ...

Abstract

The invention relates to a tire tread molding structure applicable to a driving wheel. The tire tread molding structure comprises a tire tread rubber part and a tire tread base rubber part, wherein the tire tread rubber part and the tire tread base rubber part are in triangular transition at a tire tread shoulder. The tire tread molding structure is simple and reasonable in structural design, andby improving the rubber distribution mode of a tire tread shoulder, not only is a sufficient thickness of a pattern trough bottom in the tire tread ensured, but also the tire tread is relatively goodin wearing resistance, tire tread shoulder heating is reduced, the tire tread shoulder heat radiation effect is improved, early-stage damage of a tire is reduced, the overall property requirements ofthe tire are ensured, and the service life of the tire is greatly prolonged.

Description

technical field [0001] The present invention relates to the improvement of tire tread molding structure, in particular to a tire tread molding structure suitable for driving wheels. Background technique [0002] The tire tread is usually composed of tread rubber and tread base rubber. In comparison, the tread rubber has good wear resistance but high heat generation; the base rubber has low wear resistance but low heat generation. [0003] At present, in many tire tread molding structures, the tread rubber part and the tread base rubber part adopt a trapezoidal transition at the tread shoulder 3 . Because the tread rubber of the driving wheel tire is very thick and the pattern groove is very deep, if the base rubber of the tread is thickened, the height of the base rubber is easily higher than the thickness of the bottom of the groove, and cracks at the bottom of the groove are likely to occur during the use of the finished tire. If the base rubber of the tread is thin, the ...
