FIG. 1 is a schematic side-wall structure of a conventional tire.
Fig. 2 is a schematic structural diagram of the present invention.
In the figure, 1-tread rubber, 2-sidewall rubber, 3-sidewall protection rubber, 4-carcass turn-up steel wire and 5-carcass turn-up steel wire protection rubber.
Detailed Description
Example 1
As shown in fig. 2, the present embodiment provides a sidewall structure of a mining tire, in which a lower end point of a tread rubber 1 is covered to a thickest point of a sidewall rubber 2; the outer side of the side rubber 2 is provided with a side protective rubber 3 with the thickness of 3-8mm, and the upper end point of the side protective rubber 3 covers the lower end point of the tread rubber 1 and exceeds the lower end point of the tread rubber 1 by 20-30 mm; the lower end point of the sidewall protection rubber 3 is positioned below the upper end point of the carcass turnup steel wire 4 and exceeds the upper end point of the carcass turnup steel wire 4 by 50-100 mm.
In this embodiment, the design of the sidewall is optimized, and the original sidewall rubber 2 covered with the tread rubber 1 (as shown in fig. 1) is adjusted to be the tread rubber 1 covered with the sidewall rubber 2, and the sizes of the original sidewall rubber 2 and the tread rubber 1 are kept unchanged. This is because the tread rubber 1 is generally harder than the side rubber 2 and has good cut resistance, and therefore, the cut resistance of the sidewall portion can be improved by wrapping the side rubber 2 with the tread rubber 1. Meanwhile, the sidewall protection rubber 3 is additionally arranged at the sidewall part, so that the cutting resistance of the sidewall part can be further enhanced.
Example 2
On the basis of the embodiment 1, the carcass turnup steel wire sheath rubber 5 with the thickness of 1.5-4.5mm is respectively arranged on the upper end point and the inner side and the outer side of the carcass turnup steel wire 4; the upper end points of the three carcass turnup steel wire sheath rubbers 5 are staggered up and down, and the lower end points are also staggered up and down. The type of the carcass turnup steel wire sheath rubber 5 is the same as that of the carcass rubber.
The tyre body turn-up steel wire protective glue 5 at the upper end point of the tyre body turn-up steel wire 4 is marked as a No. 2 film, the tyre body turn-up steel wire protective glue 5 is adhered to the upper end point of the tyre body turn-up steel wire 4, the tyre body turn-up steel wire protective glue 5 at the inner side and the outer side of the tyre body turn-up steel wire 4 is respectively marked as a No. 1 film and a No. 3 film, the No. 1 film and the No. 3 film cover the end part of the tyre body turn-up steel wire 4 by 35-60mm, and the lower end points of the No. 1 film and the No. 3 film are positioned and staggered by 20-30 mm.
During production, the tire side, the bead edge protective rubber, the molding rubber, the airtight layer and the isolation rubber part are sequentially laminated and pressed according to design requirements, then the 1# rubber sheet on the inner side of the tire body reverse-wrapped steel wire is laminated, tire body lamination is continuously carried out, and joints are spliced. After finishing, the 2# film and the 3# film are sequentially attached to the upper end point and the outer side of the corresponding carcass reverse-wrapped steel wire, and then the subsequent operations such as pressing, shaping and the like are carried out. After the tire blank is shaped, pressing a belt ply assembly, performing tire body turn-up and turn-up tire body back-pressing operation, subsequently performing tread rubber winding operation, after the tread rubber winding is finished, performing sidewall rubber protection 3 lamination according to design requirements, covering a winding end point and the upper end point of a tire body turn-up steel wire 4 according to requirements, then performing sidewall rubber protection 3 pressing, cone pricking and tire blank unloading operation, and finally finishing the manufacture of the tire blank.
This embodiment adds the glue protection design to the 4 upper end points positions of matrix turn-up steel wire, reaches the protection to 4 upper end points of matrix turn-up steel wire, promotes the bulk strength and the cut resistance of tire side position.
