Abstract
The utility model discloses a kind of short-distance all-steel load-bearing radial tire tread pattern structure, on the tyre surface of tire, be distributed with multiple pattern block group, comprise along the side pattern block group of tire circumference distribution and the outside pattern block group along the distribution of tire circumference, inner side or outside pattern block group staggered along circumferential line symmetry, and form through stepped cross groove, traverse furrow is widened to tire shoulder gradually by tyre surface center, and bottom of trench is provided with glue nail; Each side pattern block is connected by reinforced rib with between the pattern block of outside.The utility model can promote the towability of tire, the generation that minimizing bottom of trench horsestone and bottom of trench split.
Description
Technical field
The utility model relates to a kind of all-steel load-bearing radial tire, relates more specifically to a kind ofly be suitable for the pattern structure on tire tread of short distance to intermediate range distance travel.
Background technology
Tire is the key fitment of vehicular drive structure, and the weight of support vehicle also makes vehicle safe driving, and whole steel wire radial tyre develops into gradually, and performance degree of recognition is high, range of use tire widely.The tread portion of tire directly with earth surface friction, the steering effort of transmission vehicle, tractive force and braking force.The research of tread pattern structure and improvement effectively can improve handling, the wear resisting property of tire.
Current China basic economy is greatly developed, prosperous building industry has driven the development of transportation, and the all-steel load-bearing radial tire for mixing road surface (cement pavement between such as stone earth road pavement or town and country), short-distance traveling proposes higher performance requriements.In use, easily there is the faults such as groove bottom is torn, horsestone, affect earth-catching property and the handling of tire in short-distance tire in the market.
Utility model content
The purpose of this utility model is to overcome above-mentioned defect, develops a kind of all-steel load-bearing radial tire, which raises towability and the endurance quality of tire, reduces tire bottom of trench and splits the generation with the fault such as horsestone.
The utility model is achieved in the following ways:
A kind of short-distance all-steel load-bearing radial tire tread pattern structure, the tyre surface of described tire is distributed with multiple pattern block group, comprise along tire circumference distribution side pattern block group and along tire circumference distribution outside pattern block group, inner side or outside pattern block group staggered along circumferential line symmetry.
Connected by the reinforced rib of aspect ratio 4 ~ 5 between side pattern block, be connected by the reinforced rib of aspect ratio 5 ~ 6 between side pattern block with outside pattern block.
Side pattern block is that hexagon is block, and hexagon interior angle is set to 100 ° ~ 140 °, and outside pattern block is that hexagon is block, and hexagon interior angle is set to 70 ° ~ 230 °.
Described each pattern block tyre surface is provided with the fine groove of similar " L " shape.
Inner side or outside pattern block group staggered along circumferential line symmetry, formed through whole tyre surface stepped cross groove, the degree of depth of cross groove is 18 ~ 20mm.Cross groove extends to outside tire and forms groove.
Through stepped cross groove is widened to tire shoulder gradually by tyre surface center, and the widest part is set to 1.8 ~ 2.0 with the width ratio at the narrowest place.
Glue nail is provided with bottom through stepped cross groove.The aspect ratio of glue nail is set to 2 ~ 3, is highly set to 3 ~ 4mm, and glue nail 7 is arranged in the position of center line of cross groove.
The utility model tire protector has and runs through the sturdy cros-rib tread groove of type, ensures earth-grasping force and deceleration and stopping performance; Adopt wider block-type tread to design, between pattern block, be provided with reinforced rib, prevent from collapsing and use up block, strengthen the endurance quality of tire; Groove step design, increase row's stone ability, simultaneous buffering is out of shape, and reduces ditch and splits.
Accompanying drawing explanation
Fig. 1 is the tread contour schematic diagram of the utility model tire.
In figure: 1,2-side pattern block, 3, pattern block outside 4-, 5,6-reinforced rib, 7-glue is followed closely, 8-groove, 9-groove, and 10,11-fine groove
Detailed description of the invention
Now set forth detailed description of the invention of the present utility model by reference to the accompanying drawings:
As shown in Figure 1, the pattern block 1 being positioned at tyre surface central right is spaced along tire circumference respectively with the pattern block 2 being positioned at tyre surface center left, common composition side pattern block group.The pattern block 3 being positioned at tire shoulder is spaced along tire circumference respectively with pattern block 4, common composition outside pattern block group.
Described pattern block 1 is that hexagon is block, and hexagon interior angle is set to 100 ° ~ 140 °, strengthens the intensity of pattern block end, improves the durability of tire used.Pattern block 1 is identical with pattern block 2 shape, and direction is contrary, staggered along circumferential line symmetry.Described pattern block 3 is that hexagon is block, and hexagon interior angle is set to 70 ° ~ 230 °, and pattern block 3 is identical with pattern block 4 shape, and direction is contrary, staggered along circumferential line symmetry.
The limit that described pattern block 1 is adjacent with adjacent pattern block 2 two has approximate length, and is connected by reinforced rib 5, and the length of reinforced rib 5 and the ratio of width are set to 4 ~ 5; Described pattern block 2 is connected by reinforced rib 6 with pattern block 3, and the length of reinforced rib 6 and the ratio of width are set to 5 ~ 6.Pattern block 1, pattern block 2, pattern block 3 are linked to be horizontal entirety with pattern block 4 with reinforced rib 6 by reinforced rib 5, improve the stability of each pattern block, prevent pattern block from dropping.
Described pattern block 1, pattern block 2, pattern block 3 and pattern block 4 tyre surface middle part are provided with fine groove 10 and the fine groove 11 of similar " L " shape, can improve the holding power of tire road pavement, have heat sinking function simultaneously, also have the effect increasing aesthetic appearance.
As shown in Figure 1, the stepped transverse direction of groove 8, through whole tyre surface, gives propulsive effort, braking force and tractive force that tire is good.The degree of depth of described groove 8 is 18 ~ 20mm, and its width is widened to tire shoulder gradually by tyre surface center, and the widest part is set to 1.8 ~ 2.0 with the width ratio at the narrowest place, is conducive to groove draining spoil disposal.Groove 8 extends to tire shoulder and forms groove 9, contributes to improving tyre surface thermal diffusivity.
The row's of being provided with stone glue nail 7 bottom described groove 8, its aspect ratio is set to 2 ~ 3, is highly set to 3 ~ 4mm, and glue nail 7 is arranged in the position of center line of groove 8 at certain intervals.Glue nail 7 can increase row's stone ability, and simultaneous buffering tyre surface is out of shape, and reduces the generation that bottom of trench splits.
