Description

Technical Field

[0001] The utility model relates to the technical field of tires, in particular to a low-resistance tire. Background Art

[0002] As cars are increasingly used, car users have put forward many requirements for tire durability and economy. Among them, rolling resistance is the embodiment of all energy losses associated with rolling when the tire is loaded. For radial tires, this typical energy loss accounts for about 70%.

[0003] When a car is driving in the rain, rainwater will cause great resistance to the tire when it contacts the grooves of the tire. Although reducing the depth of the tire grooves (i.e., grooves) can reduce the resistance caused by rainwater to the tire, the above method of reducing the depth of the grooves will reduce the tire's grip. In addition, the tread of a common tire is usually provided with a continuous groove that goes around the tire. Since the grooves are long, more water adheres to the grooves, which will reduce the tire's grip. Utility Model Content

[0006] The tread is provided with a first drainage groove, a second drainage groove and a third drainage groove which are interconnected. The first drainage groove includes a plurality of drainage grooves, each of which extends along the circumferential direction. The plurality of first drainage grooves are arranged at intervals on the central axis of the tread. The second drainage grooves are symmetrically arranged on both sides of the axial direction of the first drainage groove relative to the central axis of the tread. The third drainage grooves extend along the circumferential direction, and the circumferential direction surrounds the axial direction.

Along the circumferential direction, each of the partition anti-sliding blocks is provided between two adjacent first drainage grooves, and the partition anti-sliding blocks are configured to partition the two adjacent first drainage grooves.

[0008] By adopting the above technical solution, the embodiment of the present application separates a plurality of first drainage grooves by separating the anti-sliding block, so that each first drainage groove is not connected to each other, so that the length of rainwater gathered in each first drainage groove will not be too long, thereby avoiding a significant reduction in tire grip. In addition, through the design of the second drainage groove, the first drainage groove and the third drainage groove are connected to the second drainage groove, so that the carcass of the low-resistance tire can quickly throw out rainwater when rotating, avoiding rainwater staying on the tread for too long, and reducing the impact of rainwater on tire grip.

[0009] In addition, the third drainage groove provided in the embodiment of the present application is interconnected with the first drainage groove and the second drainage groove, which can help to quickly drain the rainwater in the first drainage groove and the second drainage groove, so that the total amount of rainwater attached to the tire body is less than that of ordinary tires. While taking into account the tire grip, it also reduces the tire resistance of the low-resistance tire as a whole.

[0012] By adopting the above technical solution, the first bottom surface of the second drainage groove of the embodiment of the present application is generally inclined from the middle part of the tire body to the side part, so that rainwater on the tire body can quickly flow out from the second drainage groove.

[0013] According to another specific embodiment of the present utility model, the embodiment of the present utility model discloses a low-resistance tire, wherein the first bottom surface is inclined at an angle of 25 to 30 degrees relative to the tread.

[0030] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] refer to Figure 1The present application provides a low-resistance tire 1, comprising: a carcass 10, wherein the carcass 10 comprises a tread 11. The tread 11 is circumferentially (eg Figure 1 The tread 11 is the main part that contacts the ground during the driving of the automobile. The tread 11 is provided with a first drainage groove 201, a second drainage groove 202, a third drainage groove 203 and a partition anti-sliding block 301.

[0032] Specifically, refer to Figure 1 Combined with Figure 2 The first drainage groove 201, the second drainage groove 202 and the third drainage groove 203 are connected to each other.

[0033] The number of the first drainage grooves 201 includes a plurality, each of which extends along the circumferential direction R. The plurality of first drainage grooves 201 are spaced apart from each other on the central axis of the tread 11 (eg, Figure 2 That is, the first drainage groove 201 is opened at the center of the tread 11 of the carcass 10, and the first drainage grooves 201 in the plurality of first drainage grooves 201 are not connected to each other. Figure 2 As shown in FIG. 1 , the first drain groove 201 of the embodiment of the present application is a rectangular groove.

[0034] The second drainage groove 202 is symmetrically arranged in the axial direction of the first drainage groove 201 relative to the central axis O of the tread 11 (eg Figure 2 Exemplarily, the second drainage grooves 202 include a plurality of second drainage grooves 202 along the circumferential direction (as shown in the X direction). Figure 1 The first drainage groove 201 is provided with a plurality of second drainage grooves 202 arranged at intervals along the circumferential direction R (shown in the R direction), and the plurality of second drainage grooves 202 located on both sides of the axial direction X of the first drainage groove 201 are arranged one by one correspondingly relative to the central axis O, so as to form a plurality of groups of second drainage grooves 202 arranged at intervals along the circumferential direction R. Each group of second drainage grooves 202 extends in a V-shape along the circumferential direction R, and the V-shaped bottom of each group of second drainage grooves 202 is connected to the first drainage groove 201; but not limited thereto, the embodiment of the present application does not impose any specific restrictions on the extension direction of the second drainage grooves 202, and the extension direction of the second drainage grooves 202 can be any direction as long as it can quickly drain rainwater on the tire body 10.

[0035] The third drainage groove 203 extends along the circumferential direction R and is connected with the first drainage groove 201 and the second drainage groove 202 . The circumferential direction R surrounds the axial direction X.

[0036] The number of the partition anti-slip block 301 includes multiple ones, and each partition anti-slip block 301 is disposed between two adjacent first drainage grooves 201 along the circumferential direction R, and the partition anti-slip block 301 is configured to partition two adjacent first drainage grooves 201. That is, the multiple first drainage grooves 201 are not connected to each other by the partition anti-slip block 301.

[0037] When the car is driving in the rain, rainwater will enter the first drainage groove 201 (it should be noted that the depth of the first drainage groove 201 in the embodiment of the present application is the same as the depth of the groove of the conventional tire, for example, 6mm to 9mm) and the second drainage groove 202 on the tread 11, increasing the tire resistance of the tire body 10. However, since the partition anti-slip block 301 separates a plurality of first drainage grooves 201, so that the first drainage grooves 201 are not connected, the length of the rainwater in the first drainage grooves 201 gathered together will not be too long, thereby avoiding a significant reduction in the tire's grip.

[0038] At the same time, the embodiment of the present application uses the design of the second drainage groove 202 to enable the carcass 10 of the low-resistance tire 1 to quickly throw out rainwater when rotating, thereby preventing rainwater from staying on the tread 11 for too long and reducing the impact of rainwater on the tire's grip. In addition, the third drainage groove 203 provided in the embodiment of the present application is interconnected with the first drainage groove 201 and the second drainage groove 202, which can help quickly drain the rainwater in the first drainage groove 201 and the second drainage groove 202, so that the total amount of rainwater attached to the carcass 10 is less than that of an ordinary tire, taking into account the tire's grip while also reducing the tire resistance of the low-resistance tire 1 as a whole.

[0039] In some possible real-time ways, refer to Figure 2 Combined with Figure 1 The second drainage groove 202 includes a Figure 2 The first bottom surface 2021 is inclined (shown in the X direction), and the depth of one end 20211 of the first bottom surface 2021 close to the first drainage groove 201 is less than the depth of the other end 20212. That is, the bottom of the second drainage groove 202 (i.e., the first bottom surface 2021 mentioned above) is an inclined surface, and the side of the first bottom surface 2021 close to the first drainage groove 201 is high, and the side close to the sidewall 12 of the carcass 10 is low, and the whole is inclined from the middle part of the carcass 10 to the sidewall 12 part, so that rainwater on the carcass 10 can quickly flow out from the second drainage groove 202, and the sidewalls 12 are respectively provided on both sides of the axial direction X of the tread 11, and the sidewalls 12 extend along the circumferential direction R. Exemplarily, the first bottom surface 2021 is inclined at an angle of 25 to 30 degrees relative to the tread 11, for example, 25 degrees, 27 degrees, 28 degrees, or 30 degrees; but not limited thereto, the embodiment of the present application does not limit the inclination angle of the first bottom surface 2021 relative to the tread 11.

[0040] In some possible real-time ways, continue to refer to Figure 2 Combined with Figure 1 The tread 11 further includes a first anti-slip block 302, the first anti-slip block 302 includes a plurality of first anti-slip blocks 302, each of which is circumferentially (such as Figure 2The plurality of first anti-slip blocks 302 are arranged in the plurality of first drainage grooves 201 at intervals along the circumferential direction R. Figure 2 As shown, the first anti-sliding block 302 is fixedly connected to the tread 11 and is disposed inside the first drainage groove 201. For example, two first anti-sliding blocks 302 are disposed in each first drainage groove 201. Optionally, one or other number of first anti-sliding blocks 302 may be disposed in the first drainage groove 201, as long as the grip of the tire can be ensured, without too many restrictions.

[0041] In some possible real-time ways, continue to refer to Figure 2 Combined with Figure 1 The tread 11 also includes a second anti-slip block 303, and the second anti-slip block 303 includes a plurality of second anti-slip blocks 303, each of which is along the central axis of the tread 11 (such as Figure 2 The two components are symmetrically arranged as shown in the dashed line O in the middle.

[0042] Specifically, along the circumferential direction (such as Figure 2 The front and rear sides of each second anti-sliding block 303 are respectively provided with a second drainage groove 202, along the axial direction (as shown in the R direction). Figure 2 The first anti-sliding block 302 and the second anti-sliding block 303 are arranged at intervals, and the left and right sides of each partition anti-sliding block 301 are respectively connected with the second anti-sliding block 303. That is, the two ends of the axial direction X of each partition anti-sliding block 301 are respectively fixedly connected with a group of symmetrical second anti-sliding blocks 303 to separate the two adjacent first drainage grooves 201.

[0043] For example, Figure 2 As shown, the first anti-sliding block 302 is arranged inside the first drainage groove 201 and along the central axis O of the tread 11, the second anti-sliding block 303 is symmetrically arranged relative to the first anti-sliding block 302 along the axial direction X, the second anti-sliding block 303 is located between two adjacent second drainage grooves 202 along the circumferential direction R, and the first anti-sliding block 302 and the second anti-sliding block 303 do not contact each other.

[0044] Therefore, the embodiment of the present application not only avoids excessive rainwater from gathering in the same first drainage groove 201 on the tire body 10, but also ensures the grip of the tire by providing a partition anti-sliding block 301, a first anti-sliding block 302, a second anti-sliding block 303 and a plurality of first drainage grooves 201 that are not interconnected.

[0045] In some possible real-time ways, refer to Figure 2 Combined with Figure 1 The third drainage groove 203 includes a plurality of third drainage grooves 203 along the axial direction (such as Figure 2Furthermore, at least one of the partition anti-sliding block 301, the first anti-sliding block 302 and the second anti-sliding block 303 in the embodiment of the present application is provided with a third drainage groove 203.

[0046] For example, Figure 2 As shown, each partition anti-sliding block 301 is provided with three third drainage grooves 203 spaced apart in the axial direction X, each first anti-sliding block 302 is provided with one third drainage groove 203, and each second anti-sliding block 303 is provided with three third drainage grooves 203 spaced apart in the axial direction X. However, the present invention is not limited thereto, and the embodiment of the present application does not impose any specific restrictions on the number and distribution of the third drainage grooves 203, as long as the rainwater on the carcass 10 can be quickly discharged through the third drainage grooves 203.

[0047] In some possible real-time ways, refer to Figure 1 Combined with Figure 2 The third drainage groove 203 includes a circumferential direction (such as Figure 1 The second bottom surface 2031 is inclined along the extension direction of the third drainage groove 203 (as shown in the R direction in FIG. Figure 2 (as shown in the direction E in the figure), the depth of one end 20311 of the V-shaped bottom of the second bottom surface 2031 close to the second drainage groove 202 is greater than the depth of the other end 20312. That is, along the extension direction E of the third drainage groove 203, the second bottom surface 2031 as a whole presents an inclined surface that gradually increases from one end 20311 of the second bottom surface 2031 to the other end 20312. In other words, when the low-resistance tire 1 rotates, rainwater enters the third drainage groove 203, first passes through the end 20311 of the second bottom surface 2031 with a larger depth, and then passes through the end 20312 of the second bottom surface 2031 with a smaller depth, and then exits the third drainage groove 203, so that the rainwater on the tire body 10 can be quickly discharged from the third drainage groove 203. Exemplarily, the second bottom surface 2031 is inclined at an angle of 25 to 30 degrees relative to the tread 11, for example 25 degrees, 27 degrees, 28 degrees or 30 degrees; but not limited to this, the embodiment of the present application does not limit the inclination angle of the second bottom surface 2031 relative to the tread 11.

[0048] In summary, the embodiment of the present application can quickly drain rainwater on the carcass 10 of the low-resistance tire 1 by providing the second drainage groove 202 and the third drainage groove 203. In addition, by providing the partition anti-sliding block 301, the first anti-sliding block 302, the second anti-sliding block 303 and a plurality of first drainage grooves 201 that are not connected to each other, it is avoided that too much rainwater gathers in the same groove on the carcass 10, thereby ensuring the grip of the tire. Compared with the existing tires, the low-resistance tire 1 of the embodiment of the present application, without changing the depth of the groove (such as the first drainage groove 201) on the carcass 10, takes into account the grip of the tire and also reduces the resistance caused by rainwater to the tire as a whole.

[0049] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above contents are further detailed descriptions of the present invention in combination with specific embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. Those skilled in the art may make various changes in form and details, including making several simple deductions or substitutions, without departing from the spirit and scope of the present invention.
