Description

Technical Field

[0001] The utility model relates to the technical field of tires, in particular to a uniformly worn SUV tire pattern and a tire. Background Art

[0002] Tires are a key structure on a car and an important functional unit for the normal driving of the car. Different car models will use tires with different pattern structures according to their own driving needs. For SUV models, the design of SUV tires is also different from that of ordinary car tires.

[0003] When SUVs are actually used, the road conditions they face may be more complex and changeable than those of ordinary cars. Therefore, SUV tires will be designed with more and deeper grooves in the tread pattern design, and the tread design will also be thicker and harder. Deeper grooves can enable SUVs to have better passability and drainage performance when passing through complex muddy, gravel and other roads; thicker and harder treads can ensure the safety performance of SUV tires when they are loaded with heavy loads, and are more wear-resistant.

[0004] However, the inventors believe that even if deeper grooves and stronger treads are designed, some SUV tires may still experience uneven wear; uneven wear of tires will affect the driving stability of the vehicle and the service life of the tires; therefore, how to solve the above technical problems and design an SUV tire pattern structure with uniform wear is a technical problem that needs to be solved in the current field of tire technology.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1 .

[0028] In view of the problems mentioned in the above background technology, the embodiment of the utility model provides a uniform wear SUV tire pattern and tire to solve the above technical problems, and its technical solution is as follows:

[0029] A uniform wear SUV tire pattern, comprising:

[0030] A plurality of pattern blocks with unequal pitches extending circumferentially along the tread; specifically, there may be 3-5 pitches of varying lengths;

[0031] The pattern blocks of each pitch include a middle pattern block 11, and middle rib pattern blocks 12 and shoulder pattern blocks 13 located on both sides of the middle pattern block 11 and distributed in sequence;

[0032] A middle longitudinal main groove 1 is provided between adjacent middle pattern blocks 11 and middle rib pattern blocks 12, and a shoulder longitudinal main groove 2 is provided between adjacent middle rib pattern blocks 12 and shoulder pattern blocks 13;

[0033] A middle Z-shaped groove 3 is arranged on the middle pattern block 11 of each pitch, and a middle rib S-shaped groove 5 is arranged on the middle rib pattern blocks 12 on both sides of each pitch. The middle rib S-shaped grooves 5 on the left and right sides are centrally symmetrical to each other.

[0034] The middle Z-shaped groove 3 divides the middle pattern block 11 into pattern blocks that can evenly touch the ground, and the middle rib S-shaped groove 5 divides the middle rib pattern block 12 into pattern blocks that can evenly touch the ground. Adjacent pattern blocks are staggered in the longitudinal direction, which makes it easy for the tire to achieve uniform wear, thereby achieving high mileage and long life of the tire, and can also reduce the impact noise when the tire touches the ground.

[0035] It should be noted that the directional word "longitudinal" refers to the direction in which the tire rolls; the directional word "lateral" refers to the direction perpendicular to the mid-plane of the tire.

[0036] In this embodiment, the groove width value at the middle position of the middle Z-shaped groove 3 is smaller than the groove width values ​​at its two end positions; the groove width value at the middle position of the middle rib S-shaped groove 5 is smaller than the groove width values ​​at its two end positions.

[0037] In this embodiment, the angle α between the middle groove 3 and the center line is 50°-80°; the angle β between the middle groove 5 and the center line is 50°-80°.

[0038] In this embodiment, a shoulder shallow groove 4 is provided between the shoulder pattern block 13 and the shoulder longitudinal main groove 2; the provision of the shoulder shallow groove 4 can further increase the lateral stability and grip of the tire, improve the grip of the tire during cornering and lateral movement, and reduce the possibility of sideslip.

[0039] In this embodiment, a shoulder transverse groove 6 and a plurality of shoulder corrugated narrow grooves 7 are arranged at intervals along the circumferential direction of the tread on the shoulder pattern block 13 of each pitch; specifically, the number of the shoulder corrugated narrow grooves 7 is 1-3; wherein, the shoulder transverse grooves 6 on the left and right sides, and the shoulder corrugated narrow grooves 7 on the left and right sides are all centrally symmetrical.

[0040] The shoulder lateral grooves 6 and the shoulder wavy narrow grooves 7 are located on the shoulder pattern blocks 13 of each pitch and are arranged at intervals along the circumference of the tread. Their function is to increase the drainage performance and grip of the tire. The combination of the shoulder lateral grooves 6 and the shoulder wavy narrow grooves 7 can help drain water and provide additional grip, especially on wet or muddy roads.

[0041] In this embodiment, the outer end of the shoulder transverse groove 6 is enlarged to be in the shape of a shovel; such a design further increases the lateral stability and grip of the tire.

[0042] In this embodiment, the width of the shoulder waveform narrow groove 7 is 0.4-1.0 mm; the design of replacing the wider groove with the narrow groove reduces pump noise and impact noise, and reduces driving noise.

[0043] A tire comprises a tread that contacts the ground during driving, and the tread is provided with the uniform wear SUV tire pattern as described above.

[0044] The device embodiments described above are merely illustrative, wherein the units described as separate components may or may not be physically separated, and the components shown as units may or may not be physical units, and may be located in one place or distributed over multiple network units. Some or all of the modules may be selected according to actual needs to achieve the purpose of the solution of this embodiment.

[0045] In the present utility model, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.
