Abstract

The utility model provides an all-terrain crane tire pattern structure which comprises middle pattern blocks, shoulder pattern blocks and pattern grooves, wherein semi-connection structures are formed between the shoulder pattern blocks; groove bottom reinforcement ribs are arranged between the middle pattern blocks. Pattern structure forms are reasonably distributed, so that the problems of circumferential eccentric wear of the shoulder pattern blocks and horizontal eccentric wear of the middle pattern blocks are effectively solved, the risk of delamination of a tire tread and a tire shoulder is effectively avoided, the performance of an all-terrain crane tire is integrally improved, and the service life of the all-terrain crane tire is integrally prolonged.

Description

All terrain crane tire tread structure

Technical field

The utility model relates to a kind of tire tread structure, concrete refers to a kind of all terrain crane tire tread structure.

Background technology

All terrain crane is as safeguarding urban infrastructure, and in allotment city, the important machinery of buildings and resources plays more and more important effect in society.Coordinate the tire of this vehicle to arise at the historic moment.

At present, all terrain crane tire adopts block-type tread more, open tire shoulder design.In the process of advancing fast on the good town road of mating formation, inevitably there is the circumferential eccentric wear of shoulder pattern block in this kind of decorative pattern, the horizontal eccentric wear problem of unit tread pattern block.Bulk decorative pattern easily occurs that after long distance High-speed is travelled heat-dissipating concentrates, finally cause delamination situation this directly cause the tire stability decreases life-span to be reduced, even cause potential safety hazard.

Utility model content

The shortcoming existing for prior art is with not enough, the utility model provides a kind of all terrain crane tire tread structure, by the reasonable distribution of pattern structure form, effectively solve tire eccentric wear and heat-dissipating problem, the whole all terrain crane that improves is used tyre performance and service life.

For solving the problems of the technologies described above, the technological means that the utility model is taked is, all terrain crane tire tread structure, and it comprises middle part pattern block, shoulder pattern block and groove, between its shoulder pattern block, be half-connection formula structure, bottom of trench reinforced rib is set between the pattern block of middle part.

Above-mentioned all terrain crane tire tread structure, its half-connection formula structure is that adjacent shoulder pattern block inner side connects as one, the arc shoulder groove that arranged outside is open.

Above-mentioned all terrain crane tire tread structure, also arranges louvre on its shoulder pattern block.

Above-mentioned all terrain crane tire tread structure, also arranges radiating groove on its middle part pattern block.

Above-mentioned all terrain crane tire tread structure, its radiating groove is the semi-circular recesses at pattern block edge in the middle of being arranged on.

The utlity model has following advantage and useful technique effect:

1, tire tread structure of the present utility model adopts semi-enclosed tire shoulder design, that is: between shoulder pattern block, be half-connection formula structure, and this kind of design efficiently solves the appearance of the circumferential eccentric wear phenomenon of shoulder pattern block.

2, on tire tread structure shoulder pattern block of the present utility model, increase louvre, on the pattern block of middle part, increase radiating groove, effectively reduce the heat-dissipating of tire after long distance High-speed is travelled, effectively avoided the phenomenon of tyre surface, tire shoulder delamination.

3, on the pattern block of tire tread structure of the present utility model middle part, increase bottom of trench reinforced rib, when increasing decorative pattern contiguity, guarantee pattern block stability, avoided the generation of middle part pattern block eccentric wear phenomenon; The intercept designs such as decorative pattern adopts not, meet the cities and towns demand of middle low noise of travelling, and reduce rolling resistance, improve tire wear, increase tire life.

The specific embodiment

As shown in the figure, all terrain crane tire tread structure of the present embodiment, it comprises middle part pattern block 1, shoulder pattern block 2 and groove 3, between its shoulder pattern block 2, is half-connection formula structure, and bottom of trench reinforced rib 4 is set between middle part pattern block 1; Half-connection formula structure refers to that adjacent shoulder pattern block 2 inner sides connect as one, the arc shoulder groove 5 that arranged outside is open; Louvre 6 is also set on shoulder pattern block 2; On the pattern block 1 of middle part, radiating groove 7 is also set; Radiating groove 7 is the semi-circular recesses at pattern block 1 edge in the middle of being arranged on.

The above, only to preferred embodiment of the present utility model, be not that the utility model is done to other forms of restriction, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every the utility model scheme content that do not depart from, to any simple modification made for any of the above embodiments, equivalent variations and remodeling, still belongs to protection domain of the present utility model according to technical spirit of the present utility model.
