Description

Technical Field

[0001] The utility model relates to the technical field of tires, and in particular to a longitudinal air guide structure with the functions of strengthening the rigidity of pattern blocks and enhancing air cooling and heat dissipation. Background Art

[0002] With the development of economy and society, the demand for mineral resources is strong, which leads to the continuous improvement of labor productivity and reduction of operating costs in mines. This will lead to the following problems: first, overloading will occur; second, the running speed will be increased, which will cause the heat generated by the tires to increase.

[0003] In addition, with the development of artificial intelligence, foreign mining giants have begun to introduce driverless trucks that can work 24 hours a day without stopping. The time for vehicle maintenance or parking has been greatly reduced, which puts higher requirements on the reliability and durability, heat generation performance, and life of tires.

[0004] The current pattern design of engineering radial tires is generally designed with transverse grooves as the main grooves, and two or three longitudinal grooves as the main ones. The two longitudinal grooves are mostly longitudinal folded grooves. The pattern blocks of this type of tire are large and the overall heat dissipation performance is poor. In order to enhance the heat dissipation, some structural designs will add heat dissipation holes at the shoulder pattern blocks of the tread to increase the heat dissipation area, but because the heat dissipation holes are small and shallow, the heat dissipation effect is not good. Therefore, it is necessary to provide a structural design that can combine the rigidity of the pattern blocks and the heat dissipation performance to meet the use requirements of mining tires. Utility Model Content

[0005] The technical problem to be solved by the utility model is: to overcome the shortcomings of the prior art and provide a longitudinal air guide structure that has both enhanced tread block rigidity and enhanced air cooling and heat dissipation functions; compared with tires designed with multiple longitudinal grooves, the utility model can improve the rigidity of the tire tread blocks, reduce the possibility of blocks being cut off at the edges of the tread blocks, and reduce the severity of uneven wear of the tread pattern; at the same time, when the tire rotates, the air guide structure can increase the speed of air blowing through the air guide channel, take away more internal heat of the tire, reduce the maximum equilibrium temperature of the tire during operation, and improve the TKPH value of the tire.

[0006] The technical solution of the utility model is:

[0007] A longitudinal air guide structure that has both enhanced tread block rigidity and enhanced air cooling and heat dissipation functions includes an air guide channel longitudinally arranged on the tread block outside the longitudinal tread groove, one end of the air guide channel is an air guide port, and the other end is an air outlet, the air guide port is a slope that narrows from wide, the depth of the wide end is less than the depth of the narrow end, and the depth of the narrow end is less than the depth of the air guide channel; transverse grooves are arranged between adjacent tread blocks, the air outlet of the air guide channel is connected to the transverse grooves, and the depth of the transverse grooves is ≥ the depth at the air outlet.

[0008] Preferably, the depth at the air outlet > 50% of the depth of the air guiding channel.

[0009] Preferably, the depth of the air guiding opening ≤ 50% of the depth of the air guiding channel.

[0010] Preferably, the inclination angle α of the air guiding opening is 45° ≤ α ≤ 5°.

[0011] Preferably, the air guiding channel is a longitudinal straight groove or a longitudinal folded groove.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] The longitudinal air guiding structure of the present utility model, which combines strengthening the rigidity of the tread blocks and enhancing the air-cooled heat dissipation function, can improve the rigidity of the tire tread blocks compared with a tire designed with multiple longitudinal tread grooves, reduce the possibility of the edges of the tread blocks being cut and chipped at this position, and reduce the severity of uneven wear of the tread pattern. At the same time, when the tire rotates, the air guiding structure can increase the speed of the air flowing through the air guiding channel, take away more heat inside the tire, reduce the maximum equilibrium temperature during tire operation, and improve the TKPH value of the tire.

[0020] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions of the present utility model in conjunction with the embodiments of the present utility model.

[0021] Embodiment 1

[0022] As shown Figure 1 in the figure, longitudinal tread grooves 1 and transverse tread grooves 4 are provided on the tread of the engineering meridian tire, dividing the tread into multiple tread blocks 2. In order to improve the heat dissipation effect of the tire, this embodiment provides a longitudinal air guiding structure that combines enhancing the rigidity of the tread block and strengthening the air-cooling heat dissipation function. As shown Figure 1-3 in the figure, it includes an air guiding channel 301 longitudinally arranged on the tread block 2 outside the longitudinal tread groove 1 (i.e., on the right side of the longitudinal tread groove 1 as shown Figure 1 in the figure). The air guiding channel 301 can be in the form of a longitudinal straight groove or a longitudinal folded groove; one end of the air guiding channel 301 is an air inlet 302, and the other end is an air outlet 303. As shown Figure 4 in the figure, the air inlet 302 is located at the front end in the tire traveling direction, and the air outlet 303 is located at the rear end in the tire traveling direction. In this way, when the tire is traveling, air will enter the air guiding channel 301 from the air inlet 302 and then be discharged from the air outlet 303, thereby taking away the heat inside the tire and playing a role in heat dissipation.

[0023] Specifically, in this embodiment, as shown Figure 5 in the figure, the air inlet 302 is a slope that becomes narrower from wide, with an inclination angle α satisfying 45° ≤ α ≤ 5°. The depth of the wide end is less than the depth of the narrow end, and the depth of the air inlet 302 ≤ 50% of the depth of the air guiding channel 301. The depth at the air outlet 303 > 50% of the depth of the air guiding channel 301. After the air enters from the wide end of the air inlet 302, it will flow into the air guiding channel 301 along the slope-structured air inlet 302. The structural design of the air inlet 302 that becomes narrower from wide can increase the speed of the air blowing through the air guiding channel 301, thereby taking away more heat inside the tire and improving the heat dissipation efficiency.

[0024] At the same time, as shown Figure 1-2 in the figure, transverse tread grooves 4 are provided between adjacent tread blocks 2 in the circumferential direction of the tire. The air outlet 303 of the air guiding channel 301 is communicated with the transverse tread groove 4 and the depth of the transverse tread groove 4 ≥ the depth at the air outlet 303. After the air taking away the heat inside the tire is discharged from the air outlet 303 of the air guiding channel 301, since the depth at the air outlet 303 > the depth of the air inlet 302 of the next air guiding channel 301 and the depth of the transverse tread groove 4 communicated with the air outlet 303 ≥ the depth at the air outlet 303, this enables the air discharged from the air outlet 303 to smoothly enter the transverse tread groove 4 and finally dissipate, thereby completing the heat dissipation process.

[0025] Compared with a tire designed with multiple longitudinal grooves 1, the air guide structure of this embodiment can improve the rigidity of the tire pattern block 2, reduce the possibility of cutting off the block at the edge of the pattern block 2, and reduce the severity of uneven wear of the tread pattern. At the same time, when the tire rotates, the air guide structure can increase the speed of air blowing through the air guide channel 301, take away more heat inside the tire, reduce the maximum equilibrium temperature during tire operation, and improve the TKPH value of the tire (the TKPH value mainly reflects the operating capacity of the tire, and the larger the value, the stronger its operating capacity).
