Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 3,4, present invention is disclosed a kind of all-terrain vehicle pneumatic tire of cross-country road, the tire tread 1
By being constituted along several decorative pattern units that tire is circumferentially evenly distributed, each decorative pattern unit was included successively along tire tread center week
To main pattern block 10 that is symmetrical and being arranged alternately and secondary pattern block 20, every group of main pattern block 10 and secondary pattern block 20 are by tyre surface center
Extend respectively to the tire shoulder of both sides, tyre surface central plane is crossed on the head close to the main pattern block 10 at tyre surface center, and secondary decorative pattern
Block 20 has spacing distance between the head of main pattern block 10 and main pattern block 10；The key of the present invention is：
It is set to have positioned at every group of main pattern block 10 of tyre surface immediate vicinity and the profiled outline structure of secondary pattern block 20
The height of main pattern block decrement arc 11, the secondary pattern block decrement arc 21 of difference, i.e., main pattern block 10 and secondary pattern block 20 is respectively by leading
The initiating terminal of pattern block decrement arc 11 and the secondary pattern block decrement initiating terminal of arc 21 cross tyre surface central plane to main pattern block 10
Inner end edge is in reduction design.
As shown in Figure 5,6, it is preferable to enable main pattern block decrement arc 11 and secondary pattern block decrement arc 21 to help tire to play
Handling, main pattern block decrement arc 11 and the secondary pattern block decrement initiating terminal of arc 21 axial distance D1, D2 away from tyre surface center
Identical, main pattern block decrement arc 11 is identical with height H1, H2 at the secondary pattern block decrement initiating terminal of arc 21.Being arranged such can be effectively true
The earth balance of tyre surface center left and right sides when protecting tire ground connection, can avoid producing the beat phenomenon travelled, be greatly improved
The manipulation stability of tire running, while being also avoided that the bounce for producing left and right sides ground connection, it is ensured that the comfortableness of tire running.
To avoid the undue reduction of main pattern block 10 and the secondary height of pattern block 20 from causing the comfort property of tire to reduce, main flower
Line block 10 crosses the decorative pattern height H3 at edge the inner 12 of tyre surface central plane and reduces arc 11 or secondary pattern block for main pattern block
Reduce the 70%~90% of initiating terminal height H1, H2 of arc 21.If main pattern block 10 is crossed at edge the inner 12 of tyre surface central plane
Decorative pattern height H3 it is too small when, easily make wheel because the difference that the main pattern block 10 in tyre surface center is grounded is excessive in vehicle travel process
The phenomenon of beat easily occurs for tire, and the manipulation stability of its traveling is reduced on the contrary；If conversely, main pattern block 10 crosses tyre surface center
When decorative pattern height H3 at edge the inner 12 of plane is excessive, it will be unable to realize the profile decrement at effectively amendment tyre surface center in advance
Difference in height so that tread block growth is not enough, the manipulation stability for influenceing its cross-country road to travel on the contrary.
To ensure to provide preferably manipulation stability and comfortableness, the tyre surface center left and right sides same axis during tire running
To the height of the main pattern block decrement arc 11 at distance and secondary pattern block decrement arc 21 using the high setting such as not.This tread contour knot
Main pattern block 10 crosses tyre surface central plane and larger constraint is produced to tyre surface in structure, grows up after inflation smaller, be designed with compared with
Big decrement arc-height.Secondary pattern block 20 produces less constraint to tyre surface, grows up after inflation larger, is designed with less decrement
Arc-height.The beat that the growth difference of tyre surface left and right sides is brought is corrected by the not contour decrement arc-height being pre-designed
The problem of with bounce, it is ensured that the manipulation stability and comfortableness of tire running.At the same axial of the tyre surface center left and right sides
The main pattern block decrement height H5 of arc 11 and secondary pattern block decrement arc 21 height H6 between difference be not higher than 4mm.It is arranged such
The decline of tyre surface center left and right sides earth balance can be avoided, the manipulation stability for causing tire runout and influenceing it to travel,
Can also avoid the bounce of tire same circumferential position ground connection during circumferentially advancing excessive simultaneously, it is ensured that tire running it is comfortable
Property.
To enable main pattern block decrement arc 11 and secondary pattern block decrement arc 21 to provide optimal handling, in tyre surface
The distance between the main pattern block decrement arc 11 of heart both sides and the secondary pattern block decrement initiating terminal of arc 21 D are tire section overall width OW
35%~55%.If the distance between main pattern block decrement arc 11 and the secondary pattern block decrement initiating terminal of arc 21 D are excessive, it will mistake
The rigidity of degree reduction tire tread so that tyre contact width too increases, causes the manipulation feel of tire running to become weight, finally
Produce handling downward trend；If conversely, between main pattern block decrement arc 11 and the secondary pattern block decrement initiating terminal of arc 21
Apart from D it is too small when, it is impossible to the effective profile decrement difference in height at amendment tyre surface center in advance, it is impossible to so that tread block is grown into
Smooth ground structure is smoothed out, the handling for influenceing its cross-country road to travel on the contrary.
In addition, to ensure that each pattern block of tyre surface grows into the smooth ground structure of smooth-going, secondary pattern block decrement after tyre inflating
The radius R2 of arc 21 sets the 65% ~ 95% of the radius R1 for reducing arc 11 for main pattern block.If secondary pattern block reduces the radius of arc 21
R2 will cause secondary pattern block 20 to be grown up deficiency when too small so that can not to grow into smooth-going smooth for tread block after tyre inflating
Ground structure；If the radius R2 of secondary pattern block decrement arc 21 is excessive, it will cause the too growth of secondary pattern block 20 and produce wheel
Tire ground connection bounce, influences its comfortableness on the contrary.
When tyre inflating is travelled, in tire in the presence of cavity pressure, because main pattern block 10 and secondary pattern block 20 it
Between be provided with certain spacing distance, the tread base 30 of this interval fetters smaller, the expansion growth of tread base 30 herein compared with
Greatly, the main pattern block 10 and the secondary profile of pattern block 20 decrement difference in height at tyre surface center can be corrected in advance so that tread block into
The smooth ground connection shape of smooth-going shown in a length of Fig. 7, caused by main pattern block 10 and secondary pattern block 20 can be avoided because of undue growth
Edge protrudes, and reduces the tire bounce of traveling, it is ensured that comfortableness of the tire under cross-country road traveling.While each main pattern block
10th, the block height of secondary pattern block 20 is crossed at the inner end edge 12 of tyre surface central plane respectively to both sides from main pattern block 10
Shoulder portion gradually expands extension, can suitably reduce the rigidity at tire tread center, and the width of oversize tyre ground connection can be greatly promoted
The manipulation stability of tire running.In addition, the height of each main pattern block 10 is by crossing the inner end edge 12 of tyre surface central plane
Place gradually expands extension to side shoulder portion respectively, and suitably can reducing skid resistance when tire is turned, there is provided preferably manipulate
Performance.
Certainly, the structure of tread base 30 can use as shown in Figure 4 symmetrical using tyre surface center as symmetrical smooth arc-shaped surface
Structure, can also use the drop structure of decrement parallel with main pattern block 10 and the secondary outline of pattern block 20.
To avoid the excessive growth of tyre surface center, cause main pattern block 10 and the secondary edge transition of pattern block 20 protrusion and
Its comfortableness is influenceed, the interval width L1 between main pattern block 10 and secondary pattern block 20 is main pattern block decrement arc 11 and secondary decorative pattern
The 15%~35% of the distance between the block decrement initiating terminal of arc 21 D.Interval width between main pattern block 10 and secondary pattern block 20
When L1 sets excessive, main pattern block 10 and the secondary edge transition of pattern block 20 are grown up and cause the bounce of traveling to increase, while also holding
The ground connection for easily occurring tire tread center is uneven, finally influences its comfort property；Conversely, when main pattern block 10 and secondary pattern block
When interval width L1 between 20 sets too small, it is impossible to which effectively the profile at amendment tyre surface center reduces difference in height in advance so that tire
Face pattern block growth is not enough, it is impossible to which heart ground area forms the outer contour shape of smooth-going in the tread, it is impossible to effectively lift tire
Manipulation stability under cross-country road traveling.
In addition, the head circumferential distance L2 of every group of main pattern block 10 and secondary pattern block 20 is circumferentially-adjacent two main pattern blocks
The 35%~55% of 10 interval P.The ride comfort of centre-point earth can be increased by being arranged such, it is ensured that the comfortableness of tire running, while
Skid resistance when tire is turned, lifting tire under steam handling can suitably be lowered.
