Description

Technical Field

[0001] The present application relates to the field of tire technology, and in particular to a tire pattern and an industrial vehicle tire. Background Art

[0002] Tires are circular, ground-contacting, rolling, elastic rubber products installed on various vehicles and machinery. Typically mounted on metal rims, they support the vehicle's body, cushion external impacts, maintain contact with the road, and ensure vehicle performance. The tire's tread pattern increases friction between the tread and the road to prevent wheel slippage, enhancing the tread's ground contact elasticity. Under the influence of tangential forces between the tread and the road, the tread blocks undergo significant tangential elastic deformation, ensuring driving safety.

[0003] Existing tires are used for industrial vehicles such as forklifts, lift trucks, airport luggage tractors, and light rail vehicles. For example, the utility model with publication number CN206653864U provides a large-block tire. The large-block tire includes a large-block tread, which includes large blocks, connecting ribs, and reinforcing ribs. The large blocks are rotationally symmetrical about the incline of the tire tread. The two large blocks are connected by reinforcing ribs, and adjacent large blocks are connected by connecting ribs. The land-to-sea ratio of the large blocks is greater than 80%. The large-block tire of this utility model has a relatively balanced tread design, which reduces rolling bumps, ensures smooth operation, and is relatively wear-resistant and has a long service life. However, the very high land-to-sea ratio of the large block area reduces the tire's speed performance and increases fuel consumption. This technical problem urgently needs to be addressed. Summary of the Invention

[0004] The purpose of the utility model is to solve the deficiencies of the above-mentioned technology and provide a tire pattern and an industrial vehicle tire, which can improve the speed performance of the tire and reduce fuel consumption.

[0005] To this end, the utility model provides a tire pattern, comprising:

[0006] Center tread block, located at the centerline of the tread;

[0007] Middle tread blocks, located on both sides of the central tread block;

[0008] The shoulder tread blocks are located outside the middle tread blocks and are an integrated structure with the middle tread blocks;

[0009] First oblique tread grooves are obliquely spaced between the center pattern block and the middle pattern block, and are spaced apart in a plurality of numbers in the circumferential direction of the tire;

[0010] Second oblique tread grooves are obliquely provided on the central tread block and are spaced apart in a plurality of directions along the circumference of the tire;

[0011] The third diagonal tread groove is diagonally arranged on the middle block and is arranged at intervals in the tire circumferential direction;

[0012] The transverse shoulder groove is transversely arranged on the shoulder block and is arranged at intervals in the tire circumferential direction;

[0013] The second diagonal tread groove and the third diagonal tread groove are connected with the transverse shoulder groove, and the second diagonal tread groove and the third diagonal tread groove have the same inclination direction;

[0014] The first diagonal tread groove and the third diagonal tread groove are connected, and the inclination directions of the first diagonal tread groove and the third diagonal tread groove are opposite.

[0015] Preferably, the angle α between the central block and the width direction of the tire tread is 45°-75°.

[0016] Preferably, the angle β between the middle block and the width direction of the tire tread is 3°-15°.

[0017] Preferably, the angle γ between the shoulder block and the width direction of the tire tread is 0°-5°.

[0018] Preferably, the width of the central block is 3 times the width of the first diagonal tread groove.

[0019] Preferably, the width of the middle block is 2 times the width of the third diagonal tread groove.

[0020] Preferably, the first reinforcing rib is arranged in the first diagonal tread groove, and the first reinforcing rib has a structure of narrow in the middle and wide at both ends; the second diagonal tread groove on both sides is connected through the first reinforcing rib.

[0021] Preferably, from the third diagonal tread groove to the transverse shoulder groove on the same side of the tire tread, an inside-narrow-outside-wide shape is arranged.

[0026] The beneficial effects of the present invention are as follows: the present invention provides a tire pattern and an industrial vehicle tire, in which a first oblique tread pattern groove is arranged to separate the center pattern block from the middle pattern block. On the one hand, compared with the existing technology with a very high land-to-sea ratio of large pattern blocks, the tire pattern of the present invention adds a first oblique tread pattern groove, thereby reducing the land-to-sea ratio, improving speed performance and reducing fuel consumption to a certain extent; on the other hand, the separate arrangement of the center pattern block is not only beneficial to the vehicle's straight-line driving and flexibility when turning, but also increases the grip on the ground to prevent the vehicle from slipping, while improving speed performance and reducing fuel consumption.
