Description
Technical field
The present invention relates to tire arts, and in particular to a kind of tread patterns for truck tire.
Background technique
The Pattern Design of tire usually considers wearability, adherence properties, drainage, traveling noise, braking in the prior art
Etc. performances, for truck tire tread pattern design when, it is also necessary to consider its road conditions, loading capacity size, row for using
Sail the factors such as speed, weather conditions.Under normal conditions, annular ribs has good guiding performance and drainage performance, runs at high speed
Low noise, rolling resistance are small；Transverse pattern driveability and braking ability are more excellent than annular ribs, but lateral sliding is than longitudinal flower
Line is big, and high noise, rolling resistance are big；Dual purpose tread pattern has the advantages of both the above decorative pattern concurrently, often will be lateral to guarantee tyre performance
Decorative pattern is used cooperatively with annular ribs.There are pattern block unbalance stress for existing tread patterns for truck tire structure design
Even, tyre surface stress distribution is unreasonable, and concentrated wear is serious, tire manipulation stability and the not good enough problem of driving capability.
Summary of the invention
It is an object of the invention to for the design of existing tread patterns for truck tire structure, there are pattern block stress
Unevenly, tyre surface stress distribution is unreasonable, and concentrated wear is serious, and tire manipulation stability and the not good enough problem of driving capability mention
For a kind of tread patterns for truck tire, each pattern block is steadily contacted with ground, makes pattern block uniform force, reduces stress collection
In and tyre surface heat, so that tire driving power can be improved and improve wear-resisting property.
The present invention, which is that the following technical solution is employed, to be realized:
A kind of tread patterns for truck tire sets gradually independent block-like side pattern block from tyre surface center to two sides
And pattern block on tire shoulder, the longitudinal groove in center of fold-line-shaped is set between two laterally adjacent side pattern blocks, and two is longitudinally adjacent
Side pattern block between central cross groove is set, two side pattern blocks arranged side by side parallelogram on the whole；Side
The side annular ribs ditch of linear is set between portion's pattern block and pattern block on tire shoulder；Between two longitudinally adjacent pattern block on tire shoulders
Tire shoulder cross groove is set, and tire shoulder cross groove and tire axial are in 0~30 ° of angle, central cross groove and tire
Axial is in 5~20 ° of angles.
Further, the furrow bank of the longitudinal groove in the center and tyre surface normal are in 10~25 ° of angles；Central transverse pattern
The furrow bank and tyre surface normal of ditch are in 10~30 ° of angles.
Further, the furrow bank of the tire shoulder cross groove and tyre surface normal are in 10~30 ° of angles；Side annular ribs
The furrow bank and tyre surface normal of ditch are in 10~30 ° of angles.
Further, the bottom of trench of the longitudinal groove in the center and central cross groove is respectively provided with reinforcing rib.
Further, reinforcing rib is arranged in the bottom of trench of the tire shoulder cross groove.
Tread patterns for truck tire provided by the invention, using two linear types longitudinally main groove, cooperation side
Make tyre surface stress distribution more by choosing different groove angles and width with the integral layout of the lateral main groove of tire shoulder
Rationally, tire manipulation stability and driving capability can be improved and promote drainage performance；Especially central cross groove with
Tire shoulder cross groove is staggered, using reversed inclination angle design, guarantee that each pattern block is steadily contacted with ground, make pattern block by
Power is uniform, stress concentration and tyre surface heat is reduced, to can improve tire driving power and improve wear-resisting property.

Specific embodiment
In order to which the above objects, features and advantages of the present invention is more clearly understood, with reference to the accompanying drawing and implement
The present invention will be further described for example.It should be noted that in the absence of conflict, in embodiments herein and embodiment
Feature can be combined with each other.
Case study on implementation:
The present embodiment provides a kind of tread patterns for truck tire, as shown in Figure 1, successively setting from tyre surface center to two sides
Independent block-like side pattern block 2 and pattern block on tire shoulder 8 are set, fold-line-shaped is set between two laterally adjacent side pattern blocks 2
Central longitudinal direction groove 1, center longitudinal direction groove 1 take 15 ° with circumferential line angle, and furrow bank and tyre surface normal are in 8 ° of angles.
Arc-shaped transition is used at broken line.Central cross groove 5 is set between two longitudinally adjacent side pattern blocks 2, and center is laterally
Groove 5 and tire axial are in 15 ° of angles, and furrow bank and tyre surface normal are in 12 ° of angles, and two side pattern blocks 2 arranged side by side are whole
Upper parallelogram.The side annular ribs ditch 3 of linear is set between side pattern block 2 and pattern block on tire shoulder 8, and side is vertical
It is 0 ° to groove 3 and circumferential line angle, furrow bank and tyre surface normal are in 15 °, side annular ribs ditch 3 to tyre surface edge
Distance accounts for tyre surface beam overall about 30%, and the ratio to guarantee side pattern block 2 and pattern block on tire shoulder 8 is moderate, makes tyre surface stress distribution
More rationally.Side annular ribs ditch 3 is mutually communicated with central cross groove 5, can improve tire manipulation stability and drive
Kinetic force, and drainage performance can be promoted.
Tire shoulder cross groove 4, tire shoulder cross groove 4 and tire axis are set between two longitudinally adjacent pattern block on tire shoulders
To being in 15 ° of angles, furrow bank and tyre surface normal are in 12 ° of angles.
Central cross groove 5 is staggered with tire shoulder cross groove 4, is designed using reversed inclination angle, it is ensured that each flower
Line block is steadily contacted with ground, makes pattern block uniform force, is reduced stress concentration and tyre surface heat, is led so that tire can be improved
Draw ability, and wear-resisting property can be improved.
To improve to different road conditions, different use condition adaptability, central cross groove, the longitudinal groove in center,
Tire shoulder cross groove bottom of trench is designed with bottom of trench reinforcing rib, increases pattern block rigidity, improves the resistance to loading capability of product, extends tire
Service life.The highly desirable 5mm of central cross groove bottom of trench reinforcing rib 7, center longitudinal direction groove bottom of trench reinforcing rib 9 highly may be used
3mm is taken, 6 reinforcement height of tire shoulder cross groove bottom of trench can choose 10mm.
Embodiment described above is only that preferred embodiments of the present invention will be described, not to the scope of the present invention
It is defined, without departing from the spirit of the design of the present invention, those of ordinary skill in the art are to technical solution of the present invention
The various changes and improvements made should all be fallen into the protection scope that claims of the present invention determines.
