The tread lateral edges of the shoulder blocks 30 have a multi-step height difference, and the second pattern group 3 is formed by mirror symmetry of the first pattern group 2 with the tread center line CL as a symmetry line.
Therefore, the tire is nondirectional and easy to install through the design of the pattern blocks, the edge components of each pattern block can be improved, the sand breaking capacity is improved, and the traction performance of the tire is effectively improved through the height design of different treads of the central pattern block 10 and the middle pattern block 20; by adopting the multi-step height and fall arrangement of the transverse edges of the tread of the tire shoulder pattern blocks 30, the pattern block edge components can be increased, and the over-bending sand breaking capability and the control stability are improved.
In some examples, the center block 10 is side-by-side with the intermediate blocks 20, and the shoulder blocks 30 are located between circumferentially adjacent two intermediate blocks 20. Specifically, the tire tread 1 is composed of a center block 10, intermediate blocks 20, and shoulder blocks 30, the center block 10 and the intermediate blocks 20 being disposed laterally side by side, the shoulder blocks 30 being disposed between circumferentially adjacent two intermediate blocks 20 and axially outside.
Alternatively, the U-like groove 40 opens toward the circumferential outside of the pattern body. Specifically, the longitudinal U-shaped grooves 40 are disposed on the front and rear side treads of the central pattern block 10 to divide the tread of the central pattern block 10 into an upper H-shaped tread 10a and a lower rectangular tread 10b, the longitudinal U-shaped grooves 40 are disposed on the front and rear side treads of the middle pattern block 20 to divide the tread of the middle pattern block 20 into an upper H-shaped tread 20a and a lower rectangular tread 20b, the tread area of the shoulder pattern block 30 is increased, the axial edges are arranged in a multi-step height and height fall manner, the left and right central pattern blocks 10, the middle pattern block 20 and the shoulder pattern block 30 are arranged in a mirror symmetry manner, the tire is nondirectional and easy to install, the tread design of multiple layers of different heights of the central pattern block 10 and the middle pattern block 20 can be utilized, the edge components of each pattern block can be improved, the sand breaking capability is improved, and the traction performance of the tire is effectively improved. In addition, the tread transverse edges of the shoulder pattern blocks 30 are arranged in a multi-step height fall, so that the edge components of the pattern blocks can be increased, and the over-bending sand breaking capability and the control stability are improved.
Further, a U-shaped groove 40 is provided in the middle of each of the center block 10 and the intermediate block 20. The circumferential length L1 of the lateral portion 10a1 of the upper H-shaped tread 10a of the center block 10 and the lateral portion 20a1 of the upper H-shaped tread 20a of the intermediate block 20 is set to 30% -50% of the block circumferential length L (the circumferential length of the H-shaped tread), and the axial width L3 of the lower rectangular tread 10b of the center block 10 and the lower rectangular tread 20b of the intermediate block 20 is set to 25% -50% of the block axial width L2 (the axial width of the H-shaped tread), so that the block strength can be ensured, the sand breaking capacity can be improved, and the traction performance can be improved.
In some examples, the height H of the upper class H-tread (10 a, 20 a) is greater than the height H1 of the lower class rectangular tread (10 b, 20 b) by more than the height H2 of the U-like groove 40 groove bottom from the block. Specifically, the height H2 of the bottom of the U-shaped pattern groove 40 of the central pattern block 10 from the bottom of the pattern block is smaller than the height H1 of the lower rectangular tread 10b, the height H1 of the lower rectangular tread 10b is smaller than the height H of the upper H-shaped tread 10a, the height difference delta H is set at 1.0 mm-4.0 mm, the height H2 of the bottom of the U-shaped pattern groove 40 of the middle pattern block 20 from the bottom of the pattern block is smaller than the height H1 of the lower rectangular tread 10b, the height H1 of the lower rectangular tread 10b is smaller than the height H of the upper H-shaped tread, the height difference delta H is set at 1.0 mm-4.0 mm, sand soil cannot be effectively used for improving sand and sand-removing performance, and if the height difference is too large, the pattern block strength is insufficient, and the pattern block dropping phenomenon easily occurs.
In some examples, one side of the upper H-shaped tread 10a of the central block 10 has a first projection 11 projecting toward the intermediate block 20, and one side of the lower rectangular tread 10b of the central block 10 has a second projection 12 projecting toward the circumferential outside of the block body; one side of the upper H-shaped tread 20a of the intermediate block 20 has a third projection 21 projecting toward the center block 10, and one side of the lower rectangular tread 20b of the intermediate block 20 has a fourth projection 22 projecting toward the circumferential outside of the block body. That is, the longitudinal edge side of the upper H-shaped tread 10a of the center block 10 is projected outward to form the first projection 11, the lateral edge side of the lower rectangular tread 10b is projected outward to form the second projection 12, the longitudinal edge side of the upper H-shaped tread 20a of the intermediate block 20 is projected outward to form the third projection 21, the lateral edge side of the lower rectangular tread 20b is projected outward to form the fourth projection 22, and the longitudinal edge of the shoulder block 30 is projected inward to the axial direction of the block body to form the fifth projection 31. Therefore, the edge components of each pattern block can be further increased, the capability of sinking sand soil is improved, sand is rapidly and effectively discharged from two sides, and the traction performance of the tire is improved.
Further, the width L4 of each block protruding to the circumferential outside of the block body is set to 1.5mm to 4mm. That is, the protruding lengths of the first protrusion 11, the second protrusion 12, the third protrusion 21, the fourth protrusion 22, and the fifth protrusion 31 are 1.5mm to 4mm. Therefore, the strength of the pattern blocks can be improved, the edge components of each pattern block are further improved, and the sand breaking capacity and traction performance are effectively improved.
In some examples, a plurality of lugs 50 are provided between the adjacent two center blocks 10 and the adjacent two intermediate blocks 20 in the circumferential direction of the tire, and the plurality of lugs 50 are arranged at intervals in the tire axial direction and the tire circumferential direction. That is, the present embodiment provides two axially symmetrical rows of lugs 50, each row having 4 lugs, with a plurality of rows of lugs 50 disposed at the bottoms of the grooves between the upper and lower center lugs 10 and the two intermediate lugs 20, which further increases the edge components of the lugs 50, improves the ability to sink sand, rapidly and effectively removes sand from both sides, and improves the tire traction performance.
Alternatively, the lug 50 is rectangular-like and the side of the lug 50 facing away from the center block 10 or the intermediate block 20 has a sixth projection 51 projecting toward the circumferential outside of the block body. Further, the bump 50 is designed to be narrow at the top and wide at the bottom, the circumferential outer side close to the block body is designed to be a large section and is in chamfer transition at the bottom of the groove, and the height H4 of the bump 50 is set to be 25% -35% of the height H (the height of the upper H-shaped tread) of the block, so that the sand breaking performance of the bottom of the groove can be further improved, and the traction performance of the tire can be further improved.
In some examples, the shoulder blocks 30 have a multi-step height-fall design with a lateral edge having a height difference Δl between 0.5mm and 3mm, which can ensure block strength and further improve over-bend breaking capability and handling stability. If the circumferential width difference is too small to effectively break sand and stones, if the circumferential width difference is too large, the pattern block strength is insufficient, and the stability of overbending operation is poor.
By using the technology of the invention, tires with the specification of 110/90-19 are manufactured and arranged on the rear wheels of 450CC off-road vehicles, the real vehicle test is carried out on a sand road surface by filling air pressure of 106kPa, and the sand breaking performance, the traction performance and the over-bending control stability performance of the embodiment are all superior to those of the prior art through the real vehicle test of a driver.
