Problems solved by technology

[0002] The design specifications of the ultra-high-performance and super-large-size tire design project are: 305 / 25R32, which is currently the passenger radial tire with the largest rim size in China. There is no domestic manufacturer producing it. Therefore, the quality requirements for production equipment and raw materials are very high. Only high-quality production equipment, precise testing instruments and strict process control can ensure the precision and uniformity of each tire. Therefore, it is better than ordinary car radial tires. much higher cost

Embodiment Construction

[0028] In this example, if Figure 1 to Figure 6 As shown, a kind of ultra-high-performance super-large tire of the present invention, the specification of the super-high-performance super-large tire is 305 / 25R32 108W, the diameter of the rim is 32 inches, the width of the rim is 11J, the outer diameter is 965mm, and the section width is 313mm, the load is 1000kg.

[0029] The preparation steps of the ultra-high-performance super-large tire are as follows:

[0030] (1) Rubber mixing;

[0031] (2) Manufacturing of parts;

[0032] a) Tread: According to the characteristics of the pattern groove, specially designed tread, which solves the problem of uneven belt layer and different thickness of base rubber. The mouth shape is as follows figure 1 As shown, the black frame is the key point of the shaped tread, and the thickness is thinned according to the pattern groove, which is different from the thickness between the points of the ordinary tread, which is a gradual transition;...

Abstract

The invention discloses an ultra-high performance ultra-large sized tyre and a preparation process thereof. The specification of the ultra-high performance ultra-large sized tyre is 305 / 25R32108W, the rim diameter is 32 inches, the rim width is 11J, the outer diameter is 965mm, the section width is 313mm, and the load is 1000kg. The tyre contour designed by high-performance tyre contour design software and subjected to finite element analysis is adopted, and the advanced structural design means and the stable process control can be adopted, the volume production of the tyre with the specification is realized, simultaneously all aspects of performances of the tyre can meet the requirements, product development risks are effectively reduced and the product development period is reduced.

Description

technical field [0001] The invention relates to an ultra-high-performance over-sized tire and a preparation process thereof, which are applied to high-end sports cars and refitted sports cars. Background technique [0002] The design specifications of the ultra-high-performance and super-large-size tire design project are: 305 / 25R32, which is currently the passenger radial tire with the largest rim size in China. There is no domestic manufacturer producing it. Therefore, the quality requirements for production equipment and raw materials are very high. Only high-quality production equipment, precise testing instruments and strict process control can ensure the precision and uniformity of each tire. Therefore, it is better than ordinary car radial tires. The cost is much higher. [0003] Our company is the first manufacturer in China to design and produce this specification. The size of this specification is large, the series is low, the design requirements are high, the t...
