Description

A kind of Pneumatic belt tire promoting bizet decorative pattern eccentric wear performance

Technical field

The utility model relates to tyre technology, is specifically related to a kind of Pneumatic belt tire for promoting bizet decorative pattern eccentric wear performance.

Background technology

Tire is the necessary part of automobile, its effect is very large, and the research of tire also never stops, and the characteristic of tire has generally comprised earth-grasping force, noise reduction, braking ability etc., but also wear-resisting, high temperature resistant, anti-be full of cracks etc., wherein the generation of eccentric wear especially will be noted in wear-resisting aspect.Tire eccentric wear refers to that tire in use, because external cause, as four-wheel aligner, tire is installed, and the factors such as Container Loading overbalance cause tire uneven wear.Main manifestations is wear and tear about the decorative pattern height of single tire uneven, and wherein have side decorative pattern to decline rapidly, opposite side then weares and teares not obvious, or occurs wavy wearing and tearing before and after decorative pattern, block wearing and tearing etc.

Mostly current solution tire eccentric wear is to adopt different material prescription, or even adopts the extraordinary formula of wear hardness, but the result of test remains and occurs crown decorative pattern eccentric wear phenomenon.

Utility model content

The utility model provides a kind of Pneumatic belt tire promoting bizet decorative pattern eccentric wear performance, improves crown decorative pattern eccentric wear phenomenon.

For solving the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of Pneumatic belt tire promoting bizet decorative pattern eccentric wear performance, comprise tyre surface, described tyre surface offers four the circumferential major troughs extended in tire circumference and the multiple pattern grooves extended on tire width direction, it is wide that tyre surface is limited five different pattern blocks by described circumferential major trough, from inside tyre surface along tire width direction to tyre surface outside be followed successively by the first pattern block, second pattern block, 3rd pattern block, 4th pattern block and the 5th pattern block, described pattern block is wide is respectively the wide a of the first pattern block, the wide b of second pattern block, the wide c of 3rd pattern block, the wide d of 4th pattern block and the wide e of the 5th pattern block, five pattern blocks are wide has a/e=1 for this, b/d=1, the relation of 0.38≤b/a≤0.42 and 1.18≤c/b≤1.22.

Preferably, described a:b:c:d:e equals 1:0.4:0.48:0.4:1, fluctuates ± 0.02.

Further, the Hai Lu outside tyre surface is than the Hai Lu ratio be less than inside tyre surface, and on described first pattern block and the second pattern block, the degree of depth of pattern groove and width are less than the degree of depth and the width of pattern groove on described 4th pattern block and the 5th pattern block.

Preferably, Hai Lu inside tyre surface is compared than little by 1% in the extra large land outside tyre surface.

From above technical scheme, the utility model, on the basis ensureing excellent handling, realizes improving crown eccentric wear phenomenon by the design that pattern block is wide.

Accompanying drawing explanation

Fig. 1 is the schematic diagram that in the utility model, pattern block is wide;

Fig. 2 is the stiffness analysis result schematic diagram of the utility model tyre surface.

In figure: 10, tyre surface, 20, circumferential major trough, 30, pattern groove, the 41, first pattern block, the 42, second pattern block, the 43, the 3rd pattern block, the 44, the 4th pattern block, the 45, the 5th pattern block.

Detailed description of the invention

Below in conjunction with accompanying drawing, a kind of preferred implementation of the present utility model is described in detail.

As shown in Figure 1, described Pneumatic belt tire comprises tyre surface 10, described tyre surface offers four the circumferential major troughs 20 extended in tire circumference and the multiple pattern grooves 30 extended on tire width direction.

It is wide that tyre surface is limited five different pattern blocks by described circumferential major trough 20, from inside tyre surface along tire width direction to tyre surface outside be followed successively by the first pattern block 41, second pattern block 42, the 3rd pattern block 43, the 4th pattern block 44 and the 5th pattern block 45.Described pattern block is wide is respectively the wide a of the first pattern block, the wide b of the second pattern block, the wide c of the 3rd pattern block, the wide d of the 4th pattern block and the wide e of the 5th pattern block, and these five pattern blocks are wide has the relation of a/e=1, b/d=1,0.38≤b/a≤0.42 and 1.18≤c/b≤1.22.

Preferably, described a:b:c:d:e equals 1:0.4:0.48:0.4:1, fluctuates ± 0.02.

Adopt the tyre surface of decorative pattern rigidity FEA analysis tool to the utility model tire to analyze, the stiffness analysis of decorative pattern RIB, require the rigidity size not only can finding out each RIB, also want the symmetry situation finding out contrast and interior outside each other.Analysis result shows product of the present utility model on stiffness analysis, presents following phenomenon: decorative pattern RIB Stiffness Distribution is " W " shape in FEA analyzes, namely in the middle of, RIB is greater than both sides RIB but is less than outermost RIB and maintains position placed in the middle, the distribution of interior outside wants symmetrical, with reference to Fig. 2.

The utility model wear test:

The unit of abrasion refers to: the mileage that the ditch depth of the 1mm that often weares and teares can travel; Be exactly total after abrasion initially enough deduct the abrasion mark of 1.6mm deeply, residue is enough be deeply multiplied by unit wear.

As seen from the above table, after improving, the degree of wear of all pattern blocks closely, effectively prevent the phenomenon of tire eccentric wear.

In order to solve tire eccentric wear, need the volume ratio of tyre surface both sides close to equal, therefore further, Hai Lu outside tyre surface is than the Hai Lu ratio be less than inside tyre surface, and on described first pattern block 41 and the second pattern block 42, the degree of depth of pattern groove and width are less than the degree of depth and the width of pattern groove on described 4th pattern block 44 and the 5th pattern block 45.Preferably, Hai Lu inside tyre surface is compared than little by 1% in the extra large land outside tyre surface.

Normal design be outside Hai Lu than than the Hai Lu of inner side than little by about 5%, can ensure like this outside grab with the maximization of inner side draining, but the risk on eccentric wear is comparatively large, and adopt design of the present utility model both can meet to grab the ability of ground draining, avoid the risk of eccentric wear simultaneously.

The above embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that claims of the present utility model determine.
