Description

Technical Field

[0001] This application relates to the field of tires, and more specifically, to a structure for improving the rolling resistance of tires. Background Art

[0002] A tire is a circular ring-shaped elastic rubber product that is mounted on various vehicles or machines and rolls on the ground. It is usually installed on a metal rim, can support the vehicle body, buffer external impacts, achieve contact with the road surface, and ensure the driving performance of the vehicle. Tires are often used under complex and harsh conditions. When driving, they are subjected to various deformations, loads, forces, and high and low temperatures. Therefore, they must have high load-bearing performance, traction performance, and buffering performance. At the same time, they are also required to have high wear resistance, flex resistance, as well as low rolling resistance and heat generation.

[0003] The strip-shaped patterns in tire treads are generally composed of 3 - 5 circumferential grooves. The circumferential grooves generally adopt full-depth tread grooves or water-drop-shaped closed tread groove designs. As Figure 1 shown, the surface of the tread blocks is divided by decorative steel sheets into longitudinal tread strips, enabling the tire to have good traction, braking performance, and drainage performance. However, due to the large number of tread blocks between the transverse grooves, the overall weight of the tire is relatively heavy, thus increasing the resistance when the tire rolls. Summary of the Utility Model

[0004] To make up for the above deficiencies, this application provides a structure for improving the rolling resistance of tires, aiming to address the problem that the large number of tread blocks between the transverse grooves leads to a relatively heavy overall weight of the tire, thereby increasing the resistance when the tire rolls.

[0005] An embodiment of this application provides a structure for improving the rolling resistance of tires, including a tire tread.

[0006] A circumferential main groove extending along the circumferential direction of the tire and transverse grooves located on both sides of the circumferential main groove are provided at the middle position of the tire tread. Each of the transverse grooves is equally spaced, and each of the transverse grooves is wider in the middle and narrower at both ends. Each of the transverse grooves is arc-shaped, and the arc directions of each of the transverse grooves on both sides of the circumferential main groove are opposite.

[0007] In a specific implementation, each of the transverse grooves is filled with an elastic strip, and both sides of the elastic strip are in tight contact with the inner walls of both sides of the transverse groove.

[0008] In a specific implementation, the height of the elastic strip is half of the depth of the transverse groove.

[0009] In a specific implementation, the tread between adjacent transverse grooves forms transverse tread blocks, and each transverse tread block is arc-shaped.

[0010] In a specific embodiment, the tread between adjacent circumferential main grooves forms circumferential tread blocks, and each circumferential tread block is further provided with inclined grooves.

[0011] In a specific embodiment, a tread side is further provided at the end of the tire tread, and a chafer strip is provided on the inner side of the end of the tread side.

[0012] In a specific embodiment, a bead wire is provided at the bottom of the chafer strip, and the bead wire is hexagonal.

[0013] Beneficial effects: The overall number of adjacent transverse tread blocks is reduced, and the spacing of each transverse groove becomes smaller, making the contact between the tire tread and the ground more reasonable, reducing the friction when the tire tread contacts the ground, and thus being able to reduce the rolling resistance of the tire.

[0019] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0020] Please refer to Figures 1-3 , the present application provides a structure for improving the rolling resistance of a tire, including a tire tread 1.

[0021] Please refer to Figure 2 and Figure 3, at the middle position of the tire tread 1, there are circumferential main grooves 3 extending along the circumferential direction of the tire and transverse grooves 6 located on both sides of the circumferential main grooves 3. Each transverse groove 6 is equally spaced, and each transverse groove 6 is wider in the middle and narrower at both ends. Each transverse groove 6 is arc-shaped, and the arc directions of each transverse groove 6 on both sides of the circumferential main groove 3 are opposite. The tread between adjacent transverse grooves 6 forms transverse tread blocks 7, and each transverse tread block 7 is arc-shaped. The tread between adjacent circumferential main grooves 3 forms circumferential tread blocks 4, and each circumferential tread block 4 is also provided with inclined grooves. Among them, the overall number of adjacent transverse tread blocks 7 is reduced, and the spacing of each said transverse groove 6 also becomes smaller, making the contact between the tire tread 1 and the ground more reasonable, reducing the friction when the tire tread 1 contacts the ground, and thus being able to reduce the resistance when the tire rolls.

[0022] In this embodiment, each transverse groove 6 is filled with an elastic strip 8, and both sides of the elastic strip 8 are in tight contact with the inner walls on both sides of the transverse groove 6. The height of the elastic strip 8 is half of the depth of the transverse groove 6. Among them, through the setting of the elastic strip 8, it can prevent stones on the road surface from entering the interior of the transverse groove 6 when the tire is running. When a stone is exactly inside the transverse groove 6, the road surface exerts pressure on it, and the elastic strip 8 will have a rebounding force, so that when this part of the tire is not in contact with the ground, the stone is directly ejected from the interior of the transverse groove 6, reducing the noise during the running of the tire.

[0023] In this embodiment, a bead is further provided at the end of the tire tread 1, and a triangular rubber strip 2 is provided inside the end of the bead. A bead wire is provided at the bottom of the triangular rubber strip 2, and the bead wire is hexagonal. Among them, since the bead wire is hexagonal, the whole tire is made more stable, and the weight of the bead wire can be reduced, thereby reducing the overall weight of the tire, and thus improving the rolling resistance during the running of the tire.

[0024] The working principle of the structure for improving the rolling resistance of the tire: the overall number of adjacent transverse tread blocks 7 is reduced, and the spacing of each said transverse groove 6 also becomes smaller, making the contact between the tire tread 1 and the ground more reasonable, reducing the friction when the tire tread 1 contacts the ground, and thus being able to reduce the resistance when the tire rolls.

[0025] The above are only the embodiments of the present application and are not used to limit the protection scope of the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.

Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
