Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Example (b): as shown in fig. 1, the present embodiment provides a truck radial tire, which includes a tire crown and a tire shoulder, wherein four longitudinal grooves arranged along the circumferential direction are disposed in the middle of the tire crown, and each longitudinal groove includes two straight grooves 1 and two folding grooves 2; the two straight ditches 1 are positioned in the middle of the tire crown, and the two folding ditches 2 are respectively and symmetrically distributed on two sides of the two straight ditches 1; a plurality of first marble blocks 3 are uniformly arranged at the bottom of the straight ditch 1, and second marble blocks 4 are arranged at the bottom of the folded ditch 2; the plurality of first marble blocks 3 are uniformly distributed along the circumferential direction of the tire, and two connected first marble blocks 3 are arranged at intervals; the second marble blocks 4 are arranged continuously along the circumferential direction of the tire, and the folding degree of the second marble blocks 4 is the same as that of the folding groove 2. The two straight ditches 1 in the middle of the heavy-duty radial tire provide excellent guiding performance of the tire, the edge folded ditch 2 provides certain driving performance of the tire, when a vehicle runs on a wet or muddy road surface, the edge folded ditch 2 can effectively prevent the tire from skidding, and the straight ditches 1 and the folded ditches 2 are matched to ensure that the tire has higher traction performance and wet skid resistance; the first elastic blocks 3 at the bottom of the straight trench 1 are arranged at intervals, so that heat dissipation at the center of the tire crown is facilitated, meanwhile, the effect of protecting a belt ply and a tire body on poor road conditions can be guaranteed, and the belt ply and the tire body in the tire are prevented from being punctured; and the second marble piece 4 continuous design of 2 bottoms of bending ditch is because the tire inflates the back, the tire contacts with ground after the vehicle load, limit bending ditch 2 can widen slightly, the phenomenon that the ditch end breaks off with the fingers easily appears in the relative middle straight ditch 1 of limit bending ditch 2, the design is the intensity at the bottom of 2 ditches of limit bending ditch for continuous marble piece effective increase limit bending ditch for 2 ditches at the bottom of limit bending ditch, reduce the breach phenomenon at the bottom of the ditch, limit bending ditch 2 is close to the tire outside simultaneously, contact the stone more easily, the rubble, design into continuous marble piece, can be better to the ability of protection tire inner structure belted layer and matrix. Further, the whole trend of second marble piece 4 is unanimous with limit portion bending groove 2, and the degree of turning over of second marble piece 4 is unanimous with the degree of turning over of limit ditch, guarantees that marble piece is unanimous with the relative position apart from both sides ditch wall, has reached the protection ditch end, prevents the cracked effect at the bottom of the ditch.
Further, the height of the first marble block 3 is 2-8mm, and the interval between two connected first marble blocks 3 is 2-4 mm; the height of the second marble block 4 is 2-8 mm. First bullet stone 3 and 4 cooperation limit portions of second bullet stone and the full circular arc design of vertical slot ditch wall, this embodiment has further injectd the mode and the height that set up of first bullet stone 3 and second bullet stone 4, is favorable to improving the self-cleaning performance of tire, prevents effectively that breach, clamp stone reduction matrix body damage at the bottom of the tire ditch, and the mileage of tire is longer, the security is higher.
In order to improve the adhesive force of the tire on a wet and slippery road surface, a first transverse groove 5 is formed between two straight grooves 1, and a second transverse groove 6 is formed between the adjacent straight grooves 1 and the folded groove 2.
Further, the depth of the first transverse groove 5 and the second transverse groove 6 is 1/5-4/5 of the depth of the longitudinal groove; the first transverse grooves 5 are linear and the second transverse grooves 6 are zigzag. The depth of the first transverse groove 5 and the second transverse groove 6 is 1/5-4/5 of the depth of the longitudinal grooves, so that the friction force between the tire and the ground is increased, and the forward slip and the side slip of the tire are effectively avoided when the vehicle is braked; the first transverse grooves 5 connecting the two straight grooves 1 are straight lines, and the second transverse grooves 6 connecting the straight grooves 1 and the folding grooves 2 are folding lines, so that on one hand, the overall attractiveness of the tire is improved, on the other hand, the arrangement of the first transverse grooves 5 and the second transverse grooves 6 effectively improves the adhesive force of the tire on a wet and slippery road surface, a water film formed on the tire and a water accumulation road surface is damaged, accumulated water in a contact area is discharged, and the wet and slippery resistance of the tire is improved.
In order to improve the control stability of the tire, the crown pattern block is arranged on the crown, the shoulder pattern block 7 is arranged on the shoulder, the crown pattern block is divided into three central pattern blocks 8 by two adjacent longitudinal grooves, and the width ratio of the shoulder pattern block 7 to the central pattern block 8 is 1.2-1.6. The large-scale design is adopted, the operation stability of the tire is favorably improved, the eccentric wear and the sideslip of the tire are effectively prevented, and the service life and the sideslip resistance of the tire are improved.
