Abstract

The utility model relates to a tire, in particular to a tire for an articulated dump truck, which comprises a tread. The tread comprises pattern blocks and pattern grooves which are alternately spaced, each pattern groove comprises shoulders, and the radius of a chamfer of each pattern groove ranges from 15 to 30mm, so that contact of the pattern blocks with the pattern grooves is effectively enhanced, and bottom cracking, pattern abrasion and block shedding of the pattern grooves during running of the articulated dump truck are reduced.

Description

The radial type tip car is used tire

Technical field

The utility model relates to a kind of tire, and especially a kind of radial type tip car is used tire.

Background technology

At present, the tire tread of radial type tip car all is traditional mining decorative pattern pattern, and the performance under top load, long haul distance, high strength, abominable road conditions all can not be good satisfies operating needs.The tradition decorative pattern often occurs base of tread groove in use and splits, tire shoulder, sidewall, tyre bead delamination even blow out, and pattern block falls soon, easy stabbing bundle and cutting, abrasion are fast, the situation that lack service life.

The utility model content

The technical matters that the utility model solves is to provide a kind of radial type tip car that improves wear-resistant, anti-cutting and anti-delamination to use tire.

In order to address the above problem, the technical scheme that the utility model provides is that a kind of radial type tip car is used tire; Comprise tyre surface, tyre surface is made up of pattern block and groove, and groove comprises shoulder; Pattern block and groove are arranged alternately, and said groove rounding, radius of rounding are 15 to 30mm;

Improvement project, said shoulder are open;

Improvement project, the gross area of said pattern block are 1.2 to 1.5 times of the groove gross area.

Compare with prior art; The utility model groove adopts the wide-angle rounding; Actv. has strengthened the contiguity of pattern block and groove, reduces in the vehicle operating base of tread groove and splits and jump and use up the generation of piece phenomenon, and the shoulder of groove is open; Strengthen the spoil disposal performance of decorative pattern, and improved the shoulder heat-sinking capability; Adopt the high saturation tyre surface, make the more anti-cutting of tyre surface, puncture and wearing and tearing, pattern block and groove rectangular distribution have strengthened tyre surface single-piece heat dispersion.

Description of drawings

Fig. 1 is the local structural representation of tire protector.

Fig. 2 is the scheme drawing in B-B cross section among Fig. 1.

In the accompanying drawing, 1. pattern block; 2. groove; 3. chamfering.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.

In the prior art, the tire of radial type tip car base of tread groove often occurs and splits because unreasonable structure, tire shoulder, sidewall, tyre bead delamination even blow out, and the utility model has to a certain degree solved the problems referred to above through the structure of improving groove and pattern block.

Shown in Figure 1 is the partial schematic diagram of tire protector, because whole tread contour is identical, so Fig. 1 is enough to explain the structure of said tire.

Concrete, as shown in Figure 1, the utility model comprises: pattern block 1 and groove 2; Pattern block 1 is arranged with groove 2 alternately, and in order to increase the contiguity between pattern block 1 and the groove 2, base of tread groove splits and jumps and use up the generation of piece phenomenon in the minimizing vehicle operating; With the big fillet in pattern block 1 and groove 2 contact positions; As shown in Figure 2, the radius of fillet can be 15mm, also can be 30mm.As further improvement, the shoulder of groove 2 is processed into open, strengthen the spoil disposal performance of decorative pattern, and improved the shoulder heat-sinking capability; The gross area of pattern block 1 can be 1.2 times of groove 2 gross areas; Also can be 1.5 times of groove 2 gross areas, adopt the high saturation tyre surface, make the more anti-cutting of tyre surface, puncture and wearing and tearing; Pattern block and groove are evenly distributed, and have strengthened tyre surface single-piece heat dispersion.

Claims

1. a radial type tip car is used tire, comprises tyre surface, and tyre surface is made up of pattern block and groove, and pattern block and groove are arranged alternately, it is characterized in that, said groove rounding, radius of rounding are 15 to 30mm.

2. use tire according to the articulated tip car of claim 1, it is characterized in that, the shoulder of said groove is open.

3. use tire according to the articulated tip car of claim 1, it is characterized in that, the gross area of said pattern block is 1.2 to 1.5 times of the groove gross area.
