The structure of the utility model can improve the strength of the lower sidewall, avoid the quality problems of the lower sidewall such as the separation caused by large deformation in the using process, and further improve the service life of the tire.
Description
Technical Field
The utility model belongs to the technical field of tire design and manufacture, and particularly relates to an oblique crossing engineering mechanical tire capable of preventing a lower tire side from being hollow.
Background
According to the use characteristics of the diagonal engineering mechanical tire: (1) the sinking of the tire under high load is large, the deformation of the tire side is serious, and particularly the area of the lower tire side close to the rim is larger; (2) the lower tire side is seriously deformed, so that repeated and larger shearing stress is borne between the curtains in the area, the heat in the area is increased, the defect of hollowing is generated, and the service life of the tire is seriously influenced by the hollowing. Therefore, it is necessary to design a bias off-the-road tire capable of preventing the lower sidewall from being empty to solve the above problems.

Detailed Description
In order to make the technical solutions of the present invention better understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.
The embodiment provides an oblique crossing off-the-road tire for preventing a lower sidewall from being hollow, which comprises a tire tread 1, an outer layer cord fabric structure 2 and an inner layer cord fabric structure 3; a filling rubber sheet 5 is arranged between the outer layer cord fabric structure 2 and the inner layer cord fabric structure 3;
the inner layer cord fabric structure 3 is internally wrapped with a steel wire ring 4;
the lowest point of the filling rubber sheet 5 is positioned at the upper end of the bead ring by 0-5mm, and the highest point is higher than the central position of the lower sidewall but not higher than the central position of the diagonal off-the-road tire.
The filling rubber sheet 5 is in an obtuse triangle shape, and the thickness of the thickest point of the filling rubber sheet is not more than 9 mm.
The filling rubber sheets 5 are positioned on two sides of the diagonal engineering mechanical tire, and the number of the filling rubber sheets 5 on each side is not less than 1.
Specifically, the lower point of the filling rubber sheet 5 is 2mm at the upper end of the bead ring, the length of the longest side is 100mm, and the higher point is higher than the central position of the lower sidewall; the thickness of the thickest point of the filling film is 9 mm; the 300 percent of the filling rubber sheet has a definite elongation of 14.3MPa, the 300 percent of the sidewall rubber has a definite elongation of 7.5MPa, and the filling rubber sheet 5 is far higher than the sidewall rubber.
According to the comparison of endurance performance tests, the method can enhance the strength of the lower tire side, effectively reduce the shear stress generated by the flexural deformation of the lower tire side, reduce the compression heat generation of lower tire side parts, enable the tire to become a tire with a lower tire side void prevention type, further solve the problem of the lower tire side void of the oblique engineering mechanical tire and avoid the early damage of the lower tire side of the tire under high load.
The utility model can improve the lower tire side strength of the oblique engineering mechanical tire, avoid the use quality problems of the tire side void and the like under high load, and avoid the early damage of the tire under overload condition, and the design has strong practicability and wide market application prospect.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing detailed description, or equivalent changes may be made in some of the features of the embodiments described above. All equivalent structures made by using the contents of the specification and the attached drawings of the utility model can be directly or indirectly applied to other related technical fields, and are also within the protection scope of the patent of the utility model.
