Specific embodiment
The embodiments of the present invention is explained below in conjunction with attached drawing:
As shown in Figure 2,3, 4, the utility model discloses a kind of rocky terrain air tread pattern structure design,
The tire tread 1 is made of several pattern blocks 10.A plurality of shape indents 20, each shape indent 20 are distributed on each pattern block 10
Compression unit 21, sealing 22 and buffer part 23 are successively arranged from center toward outer rim.The compression unit 21, sealing 22 and buffer part
23 each edge is arranged in parallel.The line of centres of each shape indent 20 and prolonging for corresponding pattern block 10 on each pattern block 10
It is identical to stretch direction.As shown in figure 5, sealing 22 is slow toward buffer part 23 after tire load-bearing when tire is in rocky terrain downward driving
Punching deformation, Fast Compression and can release the air in compression unit 21, while closed compression space is formed in compression unit 21, benefit
Increase tread block 10 to the road holding of rocky terrain, to promote the hauling ability of tire with the pressure difference of atmosphere.
The enough pressure differences of demand are adjacent on same pattern block 10 to increase pattern block road holding when in view of tire running
The width of the distance between two 20 centers of shape indent D1 two shape indents, 20 line of centres vertical direction corresponding on pattern block 10
The ratio for spending D is 0.5 ~ 1.The distance between too small 20 center of shape indent D1 will will be greatly reduced the rigidity of pattern block 10, increase
The tendency of 10 abnormal destruction of texture mapping block leads to tyres durable performance downward trend, while can also reduce to hauling ability
Promote effect；Conversely, the distance between excessive 20 center of shape indent D1 can not will continuously be provided in tire running it is enough
Pressure difference increases rocky terrain road holding, influences the promotion of tire hauling ability.The edge of shape indent 20 is round or polygon
Regular shape.The air that 21 bottom of compression unit can so be gone out convenient for energy quick release when the buffering deformation of sealing 22, is conducive to shape
The hauling ability of tire is promoted at effective pressure difference.
Further to promote hauling ability, the diameter D2 of compression unit 21 and the ratio of 10 width D of pattern block is 0.20 ~
0.45.Too small 21 diameter D2 of compression unit is effectively compressed area for reduction compression unit 21, to reduce pattern block 10 to rock
The road holding of landform influences the promotion of tire hauling ability；Conversely, excessive 21 diameter D2 of compression unit will make tire go in ground connection
In sailing, it is easy to appear the phenomenon that can not forming closed compression space, eventually leads to the result that can not effectively promote hauling ability.
The inner wall 211 of compression unit 21 is formed from pattern block surface to bottom to the inclined extension mode in 21 center of compression unit, compression unit
The setting that 21 inner wall 211 can be a plane or an arc surface, the setting that can also be combined certainly for plane, cambered surface.So it can be achieved
Quick release goes out the air of compression unit 21 and forms effective pressure difference, plays the promotion effect of hauling ability.The depth of buffer part 23
The ratio for spending the depth H 1 of H2 and compression unit 21 is 1.1 ~ 1.5.It can be conducive to sealing 22 when tire running to send out to buffer part 23
Change shape, can quick release compression unit 21 air to promote the hauling ability of tire.Another embodiment as shown in Figure 6

The root intensity that can ensure that the inner wall 211 of compression unit 21 avoids sealing 22 in repeated deformation there is a phenomenon where destroying, really
Protect the endurance quality of tire.
As shown in Figure 2,3, sealing 22 protrudes from the height difference H 4 on pattern block surface and sealing 22 and pattern block surface
It is the 5% ~ 20% of block height H.During tire running, the height difference H 4 on too small sealing 22 and pattern block surface will
The sealing effect when edge and rocky terrain for substantially reducing sealing 22 are grounded, influences the promotion of hauling ability；Conversely, excessive
Sealing 22 and the height difference H 4 on pattern block surface will will cause the premature failure at 22 edge of sealing, can do nothing to help promotion and lead
Draw performance.The ratio of the diameter D2 of the width D 3 and compression unit 21 of sealing 22 is 0.35 ~ 0.60.The width of too small sealing 22
Degree D3 will will cause 22 premature failure of sealing, can do nothing to help and promote hauling ability while also resulting in becoming for endurance quality decline
Gesture；Conversely, the width D 3 of excessive sealing 22 will excessively enhance the rigidity of sealing 22, sealing 22 is caused to have cannot achieve
Effect deformation, substantially reduces the promotion effect of hauling ability.
The inner wall 231 of buffer part 23 is formed from pattern block surface to bottom to the inclined extension side in 21 center of compression unit
Formula.The setting that inner wall 231, outside wall surface 232 can be a plane or an arc surface, the setting that can also be combined for plane, cambered surface.So may be used
Buffer part 23 conducive to sealing 22 toward outside deforms, can quick release compression unit 21 air to promote the traction property of tire
Energy.Inner wall 231 and the angle α on 10 surface of tread block are 10 °~30 °.Too small inner wall 231 and tread block 10
The angle α on surface will make the excessive decline of 23 edge rigid of buffer part, lead to 23 early damage of buffer part and cannot achieve
The promotion of hauling ability；Conversely, excessive inner wall 231 and the angle α on 10 surface of tread block will will affect sealing 22
Buffer part 23 toward outside deforms, and can not effectively promote the hauling ability of tire.The width D 4 and sealing 22 of buffer part 23 are wide
The ratio for spending D3 is 0.20 ~ 0.45, so forms enough cushion spaces in buffer part 23, convenient for the delaying toward outside of sealing 22
Rush the deformation of portion 23.To avoid the rigidity decline at 10 edge of tread block that the endurance quality of tire is caused to decline, two neighboring shape
The buffer part 23 of indent 20 can be the intercommunication that is connected.
It is as shown in Figure 7,8 another embodiment, shape indent 20 can also be according to the shape of pattern block 10 using single
The setting of compression unit 21.In addition, single compression unit 21 can be respectively equipped with a notch 213 along the front and rear edges of tire circumferential direction.Such as
This can avoid the repeated deformation of the compression unit 21 of pattern block 10 when driving, form buffer area deforming larger circumferential edge, can
Reduce the destruction of 21 circumferential notch of compression unit, it is ensured that the endurance quality of tire.It is illustrated in figure 9 another embodiment, shape pressure
