Description
Technical field
The present invention relates to a kind of truck tyre, specifically, relate to a kind of pattern structure of tire protector of autotruck.
Background technology
The control ability of truck tyre road pavement, treadwear degree require higher.Improving road surface control ability generally improves from three aspects: the selection of the formula of rubber, the structure of tire and tread contour, key is the selection to tread contour.
In prior art, the Pattern Design of tire is considered the performances such as resistance to abrasion, adherence properties, drainage, the noise that travels, braking ability conventionally, for tire tread pattern when design of autotruck, conventionally to consider the factors such as road conditions, load carrying ability size, moving velocity, climatic conditions of its use.Generally, circumferential pattern has good guidance quality and drainage performance, and the noise of running at high speed is low, rolling resistance is little; Cros-rib tread driveability is more excellent than circumferential pattern with deceleration and stopping performance, but lateral sliding is larger than circumferential pattern, and noise is high, rolling resistance is large; Dual purpose tread pattern has the advantage of above two kinds of decorative patterns concurrently, for guaranteeing tyre performance, often cros-rib tread and circumferential pattern is used in conjunction with.The wet-sliding resistant performance of tire protector, wear resisting property and low-rolling-resistance characteristic, by people, be called " devil's triangle ", the improvement of certain performance will certainly affect the raising of other performance, autotruck is higher to performance requriementss such as the resistance to abrasion of tire, handlings, and the selection of tread contour is also most important.
Summary of the invention
The invention provides the tread patterns for truck tire that a kind of handling is good, propulsive effort is strong, wear resisting property is excellent, be suitable for long-distance, middle-long distance driving position of wheel use.
Heavy-duty truck tyre tread of the present invention, comprise the center running lug along the circumferential direction extending, sidepiece pattern block and pattern block on tire shoulder, center running lug, sidepiece pattern block and pattern block on tire shoulder are the block structure of polygon independently, tyre surface central authorities are provided with central longitudinal to groove, central longitudinal is followed successively by center running lug from the inside to the outside to the groove left and right sides, sidepiece pattern block and pattern block on tire shoulder, between center running lug and sidepiece pattern block, between sidepiece pattern block and pattern block on tire shoulder all by circumferential pattern ditch interval, each center running lug, on sidepiece pattern block and pattern block on tire shoulder, be equipped with L-type shallow slot groove, L-type shallow slot groove be take central longitudinal and is oppositely arranged to groove as axle.
L-type shallow slot decorative pattern can cut off moisture film, and wet-skid road surface tire is grabbed more firm, and wet-skid road surface control ability is high, can play thermolysis simultaneously, and elegant in appearance.
Between two longitudinal adjacent center running lugs, between two longitudinal adjacent sidepiece pattern blocks, all by cross groove A interval, between two longitudinal adjacent pattern block on tire shoulders, by cross groove B interval, two horizontal adjacent pattern blocks are interspersed.
Cross groove and circumferential pattern ditch are crisscross, perforation mutually, are beneficial to the smooth and easy discharge of air overstocked in travelling, and greatly reduce the generation of noise, have improved the drainage performance at wet-skid road surface simultaneously.
Described cross groove B and tire axial angle are 10～20 °, and furrow bank and tyre surface normal angle are 5～12 °, and cross groove A is parallel with tire axial, and furrow bank and tyre surface normal angle are 5～12 °.
Cross groove A and tire axial keep certain angle, can guarantee good road traveling performance, cross groove A and cross groove B furrow bank and tyre surface normal are certain angle, and cros-rib tread bank circumferential line is symmetric offset spread, can effectively prevent from travelling the sandwiching of the foreign matters such as middle stone, improves tractive property and the drainage performance of tire greatly.
Described central longitudinal is U-shaped to groove, along the circumferential direction extend straight, with circumferential line angle be 0 ℃, greatly reduced the rolling resistance of tire.
Described central longitudinal is provided with discrete bottom of trench reinforced rib A to groove bottom of trench.
Described bottom of trench reinforced rib A is highly the 30%-60% of the center groove degree of depth, and length is the 30%-50% of a center running lug length.
Cross groove A bottom of trench is provided with bottom of trench reinforced rib B, and cross groove B bottom of trench is provided with bottom of trench reinforced rib C, and the height of bottom of trench reinforced rib C is greater than the height of bottom of trench reinforced rib B.
Bottom of trench reinforced rib has increased the rigidity of center running lug, sidepiece pattern block and shoulder pattern block, can effectively avoid tyre surface irregular wear, improves the service life of tire.
Described circumferential pattern bank tyre surface circumferencial direction extends, with circumferential line angle be 5～10 °, furrow bank and tyre surface normal angle are 5～12 °.
The tyre surface of all tires is all comprised of pattern block and groove, and that pattern block and groove are divided into is horizontal and vertical, the tyre surface of tire adopts groove or pattern block, and be that employing is horizontal or longitudinal, all need the application target according to tire, and carry out countless experiments and verify, and a certain pattern block employing laterally still longitudinally need to be considered in conjunction with tire is whole.The tread structure of tire need to be seen the integral structure of surface of tyre, as the overall ratio of groove, pattern block, and angle of inclination, auxiliary groove etc., its structure each other, coordinate and there is strict requirement, need to carry out accurate scientific experiment according to different pattern blocks.The overall performance of tire can not be confined to some grooves or pattern block, and some pattern blocks of tire protector or groove are different, and the performance of tire and effect are likely completely different.This tire pattern structure, by experiment many times of technical personnel and by practical application, improves pattern structure, and final pattern structure has been obtained unexpected technique effect.
Compared with prior art, the invention has the beneficial effects as follows: L-type shallow slot decorative pattern can cut off moisture film, improve the control ability of wet-skid road surface; Circumferential pattern ditch and cross groove are crisscross, perforation mutually, air overstocked in travelling can be got rid of smoothly, reduce the noise that travels, and have greatly improved the driveability of tire; Bottom of trench reinforced rib the rigidity that has strengthened pattern block is set, can avoid irregular wear, improve Using Life of Tyre; The furrow bank of groove and tyre surface normal arrange at an angle, can prevent that the foreign material such as handstone from sandwiching reduction Using Life of Tyre, improve tire maneuvering performance and tractive property.
