Abstract

The invention discloses a mining pattern of a load meridian automobile tire. The mining pattern comprises pattern grooves, wherein pattern blocks are formed among the pattern grooves; each pattern groove comprises tire shoulders at the two sides of a center line of a tread, and a left long oblique pattern groove and a right long oblique pattern groove which are formed in a staggered way at an interval on a crown; the inner ends of the corresponding left long oblique pattern grooves and right long oblique pattern grooves are connected with each other by reversed short oblique pattern grooves; the midpoints of the short oblique pattern grooves are positioned on the center line of the tread; the outer ends of all the long oblique pattern grooves horizontally extend to the side walls of the tire from the tire shoulders; the adjacent long oblique pattern grooves formed in the tire shoulder and the crown which are positioned at the same side are connected by longitudinal short pattern grooves. The mining pattern of the load meridian automobile tire is powerful in road holding, enough in rigidity, less in creep temperature rise, good in heat dispersion and long in service life.

Description

Heavy load radial automobile tire is mining decorative pattern

Technical field

The present invention relates to off-the-road tyre structure, the specially a kind of mining decorative pattern of heavy load radial automobile tire.

Background technology

Heavy load radial automobile mining tyres, as its load-bearing is big, pull strength big, use the factors such as road conditions complexity, are simultaneous The index requests such as its adherence properties and wearability and thermal diffusivity are turned round and look at, the tyre surface of radial generally employ different types of flower Stricture of vagina structure is to adapt to its performance requirement.

As the tread contour of most common mining heavy load radial automobile tire, corrugated groove is employed, described Groove on tyre surface horizontal (axial direction of tire) interval setting and tyre surface is divided into the pattern block of circumference uniform distribution, this load-carrying Automobile radial tire has found following defect in use：

1st, trend in the horizontal many of groove and few in the vertical so that the transverse grip of tire is not enough and easy Break away.

2nd, the relatively independent and area of each pattern block is big, and easily wriggling produces temperature rise and radiating is slow, causes tire easily aging.

3rd, easily foreign body being snapped in groove and be difficult to discharge, is easily damaged tyre surface.

Content of the invention

For solving the deficiencies in the prior art, the present invention proposes a kind of mining decorative pattern of heavy load radial automobile tire.

The mining decorative pattern of heavy load radial automobile tire of prior art problem is can solve the problem that, its technical scheme includes decorative pattern Ditch, forms pattern block between the groove, except that the groove includes the tire shoulder of circumferential line both sides and tire The left and right oblique long groove that interval opens up and misplaces is labeled, the inner of corresponding left and right oblique long groove passes through reversely The connection of oblique short groove, the midpoint of the oblique short groove on circumferential line, each oblique long groove outer End is extended laterally from tire shoulder at sidewall, by the short flower in longitudinal direction between adjacent oblique long groove on homonymy tire shoulder and crown Groove connects.

Further, the width of the oblique long groove is gradually reduced at crown and at sidewall respectively from tire shoulder.

Further, be provided with the oblique long groove at crown can self-cleaning tire one or more is raised.

Further, in the oblique long groove in the oblique short groove and at tire shoulder, connection adjacent lugs are provided with Reinforcement.

Ground ability is longitudinally grabbed for improving tire, oblique short groove on the pattern block of shoulder region, is offered, described oblique short The direction of groove is consistent with the direction of oblique long groove.

For improving combination property, homonymy separately a group longitudinally the position consistency of short groove and is partial to tire shoulder side, Another group separately longitudinally the position consistency of short groove and be partial to crown side.

Further, the short groove in the longitudinal direction is designed as rolling over shape.

Beneficial effects of the present invention：

1st, heavy load radial automobile tire of the present invention mining decorative pattern adopts special network, reasonable distribution tire Horizontal and vertical earth-grasping force.

2nd, the self-cleaning ability of the present invention is strong, and service life strengthens.

3rd, the rigidity of pattern block of the present invention is strong, and the wriggling for reducing in tire running heats up, it is therefore prevented that the carrying of tire Front aging.

4th, the thermal diffusivity of the present invention is more preferable.

Description of the drawings：

Fig. 1 is the structural representation of one embodiment of the present invention.

Figure number is identified：1st, oblique long groove；2nd, oblique short groove；3rd, the short groove in longitudinal direction；4th, raised；5th, oblique short Groove；6th, reinforcement.

Specific embodiment

Illustrated embodiment is described further to technical scheme below in conjunction with the accompanying drawings.

Heavy load radial automobile tire of the present invention is mining decorative pattern, including groove, forms pattern block between the groove.

The groove is opened up on the tire shoulder of circumferential line both sides, crown, sidewall respectively：

On tire shoulder and crown on the left of circumferential line, parallel interval arranges the oblique long groove 1 of left position, tyre surface center On tire shoulder and crown on the right side of line, parallel interval arranges the oblique long groove 1 of right position, the oblique long groove 1 of left and right position Incline direction is identical, being staggeredly located of the corresponding oblique long groove 1 in left and right position, the oblique long flower in the left and right position being staggeredly located The inner of groove 1 is connected by reverse oblique short groove 2, and the outer end of each oblique long groove 1 is from tire shoulder at sidewall Extend laterally, the midpoint of the oblique short groove 2 is on circumferential line, and the width of each oblique long groove 1 is from tire shoulder Place is gradually reduced at crown and at sidewall respectively, by folding between adjacent oblique long groove 1 on homonymy tire shoulder and crown Longitudinally short groove 3 connects shape, and homonymy separately a group longitudinally the position consistency of short groove 3 and is partial to tire shoulder side, phase Interval another group longitudinally the position consistency of short groove 3 and be partial to crown side, as shown in Figure 1.

Be provided with oblique long groove 1 at crown can self-cleaning tire inside and outside two projections 4；In oblique short groove 2 With the reinforcement 6 for being provided with connection adjacent lugs in oblique long groove 1 at tire shoulder；Offer on the pattern block of shoulder region The oblique short groove 5 consistent with oblique 1 direction of long groove, as shown in Figure 1.
