Abstract
The utility model discloses a bias engineering tire with pattern blocks with increased strength, which comprises tread pattern blocks. Pattern grooves are formed between each two adjacent pattern blocks, reinforcing ribs for strengthening the strength of the pattern blocks are disposed in the pattern grooves in the middle of a tread and tamped in the pattern grooves, the top ends of the reinforcing ribs are lower than those of the pattern blocks, recesses can also be inwards arranged on the top surfaces of the reinforcing ribs and are multi-stage step recesses with the sizes reduced gradually, the recesses lead to the bottoms of the pattern grooves and are symmetrical to the centers of the pattern grooves, and the reinforcing ribs and the pattern blocks are made of the same rubber and can be simultaneously in vulcanization forming. The bias engineering tire increases tread abrasion resistance and puncture resistance to the utmost extent, minimizes tread damage, and prolongs service life.
Description
(1) technical field:
The utility model relates to tire, is a kind of oblique off-the-road tyre that improves pattern block intensity specifically.
(2) background technology:
Tread structure is mainly tread contour, is made of pattern block, forms groove between the adjacent pattern block, and the design goal of pattern block is to travel, dispel the heat, grab performance characteristics such as ground, traction for what adapt to tire.Giant engineering machinery tyre is because moving velocity is slow and running environment is abominable unusually, particularly load is big especially, the various power (as tractive force) of friction between tire and the road surface and transmission constantly increase, cause the wearing and tearing and the puncture degree of tyre surface to increase, thereby cause problems such as tyre surface delamination, chunk-out, cause tire to produce early damage, have a strong impact on tire life, and then also have influence on the maneuvering performance of engineering machine vehicle.
(3) utility model content:
The utility model has designed a kind of oblique off-the-road tyre that improves pattern block intensity, its objective is to prolong tire service life, ensures maneuvering performance.
Can realize the oblique off-the-road tyre of the raising pattern block intensity of above-mentioned purpose, comprise tread block, form groove between the pattern block, different is that the reinforced rib that strengthens pattern block intensity is set in the groove at tyre surface middle part, to alleviate the degree that tire tread block is damaged.
The most sturdy reinforced rib form is the reinforced rib that tamps in groove, and this reinforced rib connects into adjacent pattern block as a whole.
For reducing the abundant degree of reinforced rib, can lower the height of described reinforced rib, promptly the end face of reinforced rib is lower than the pattern block end face.
For improving the radiating effect of reinforced rib, can offer the recess that is symmetrical in the groove center from the end face inside (descending) of reinforced rib.
The circumferencial direction width of described recess reduces gradually, and the axial width of recess increases gradually, to guarantee the intensity of reinforced rib bottom.
Described recess is typically designed to multistage bench port.
The recess of described different shape can be offered to the groove bottom.
Described reinforced rib is selected sizing material and the while sulfidization molding same with pattern block for use.
Advantage of the present utility model:
The oblique off-the-road tyre that the utility model improves pattern block intensity has increased substantially the wear-resistant and anti-puncture performance of tyre surface, the damage of tyre surface is dropped to minimum, the prolongation tire life.
(4) description of drawings:
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Figure number sign: 1, pattern block; 2, reinforced rib.
(5) specific embodiment:
The oblique off-the-road tyre that the utility model improves pattern block intensity comprises tread block 1, forms groove between the pattern block 1 in twos, is provided with the reinforced rib 2 of strengthening pattern block 1 intensity in the groove at tyre surface middle part.Described reinforced rib 2 is symmetrical in both sides, groove center and distributes, be two-stage step shape gusset from bottom to top, the bottom surface of subordinate's reinforced rib 2 is connected the groove bottom, the end face of higher level's reinforced rib 2 is lower than pattern block 1 end face, two-stage reinforced rib 2 opposing sides are connected on the groove sidewall, as shown in Figure 1.
According to the specification of variety classes oblique off-the-road tyre, the radial height of higher level's reinforced rib 2 is chosen as 75%～80% of the groove degree of depth, and the axial width of higher level's reinforced rib 2 is chosen as tread width 15%～20%; The radial height of subordinate's reinforced rib 2 is chosen as 40%～50% of the groove degree of depth, and the axial width of subordinate's reinforced rib 2 is chosen as tread width 35%～40%, as shown in Figure 1.
Reinforced rib 2 is with a kind of sizing material with pattern block 1, moulding simultaneously in vulcanization process.
