Description

Technical Field

[0001] The invention relates to the technical field of tire production, in particular to a studded tire. Background Art

[0002] In winter, the road is covered with a lot of ice and snow. When the tires are driving, a layer of water film will form between the tires and the ice and snow road, which will reduce the friction between the tires and the road, causing the tires to slip, thus posing a great threat to the safety of drivers and pedestrians. In view of this problem, people have developed snow tires for such roads. By embedding anti-skid spikes in the tires, the friction between the tires and the road is increased, thereby achieving an anti-skid effect.

[0003] However, the studded tires designed in the prior art have at least the following disadvantages including but not limited to: 1. The distance between the anti-slip spikes and the horizontal and vertical grooves is poorly designed, which causes the anti-slip spikes to fall off early.

[0004] 2. The number of anti-skid studs in each meter of rolling circumference does not exceed 50. This results in point contact between the anti-skid studs and the ice surface during driving, resulting in poor grip and handling.

[0005] In view of the above-mentioned shortcomings, the studded tires designed by the prior art are not satisfactory in terms of anti-skid performance. In view of this, it is necessary to improve the above-mentioned defects. Summary of the invention

[0006] The invention provides a studded tire, which is used to solve the defects in the prior art that the anti-skid studs are detached due to the poor design of the distance between the anti-skid studs and the transverse and longitudinal grooves, and the poor gripping force due to too few anti-skid studs.

[0007] The present invention provides a studded tire, comprising a tire body, the tire body comprising a tread crown, sidewalls are arranged on both sides of the tread crown, beads are arranged on the sidewalls for fixing the tire on a rim, a plurality of nail holes are arranged on the tread crown, and further comprising: A transverse pattern is provided on the tread crown, and the tread crown is divided into a plurality of longitudinal tread blocks by the transverse pattern, and the side edges of the tread blocks extend to the sidewalls; Longitudinal patterns are arranged on the divided tire blocks, wherein one of the longitudinal patterns divides the tire block where it is located into tread 1 and tread 2, and the remaining longitudinal patterns divide the tread 1 or tread 2 where it is located into a plurality of pattern blocks, and each of the pattern blocks is provided with a plurality of sipes; A steel sheet group, the steel sheet group includes several steel sheets of different specifications, which are inserted into the inside of the knife groove; Anti-skid spikes, the anti-skid spikes are arranged inside the spike holes, and the number of anti-skid spikes on each tire is not less than a predetermined number; The transverse pattern, the longitudinal pattern and the tread one and the tread two divided therefrom can improve the grip of the tire, and the wear of the tire on the ground can be reduced by the steel plate group and the anti-skid spikes.

[0008] According to the studded tire provided by the present invention, the pattern blocks present different angles, and the angles change with the positions of the pattern blocks on the tire block.

[0009] According to a studded tire provided by the present invention, the tire further comprises reinforcing ribs, wherein the reinforcing ribs are arranged in the transverse pattern to improve the rigidity of the pattern blocks, and the reinforcing ribs change with the angle of the pattern blocks.

[0010] According to the studded tire provided by the present invention, the length of the steel sheet in the steel sheet group changes with the change of the angle and shape of the tread block.

[0011] According to the studded tire provided by the present invention, the stud holes are equally spaced on the tire crown, and when the equally spaced stud holes encounter a transverse pattern or a longitudinal pattern, they are horizontally moved to a nearby contactable surface; When the nail hole and the pattern of the tread crown overlap, the nail hole covers the original pattern of the tread crown; When the diameter of the nail hole protrudes beyond the pattern block, the protruding portion is filled according to the diameter of the nail hole, or the size of the protruding nail hole is adjusted according to actual conditions.

[0012] According to the studded tire provided by the present invention, a pattern layer is arranged around the stud holes, and the pattern layer is used to fill and adjust the positions of the anti-skid studs.

[0014] According to a studded tire provided by the present invention, the filling and adjustment of the position of the anti-skid studs by the pattern layer should satisfy the following conditions: the stud bodies of the anti-skid studs are located below the radial side surface of the tire, and the stud cores thereof protrude from the tire surface, so as to reduce the damage of the anti-skid studs to the road surface.

[0015] According to a studded tire provided by the present invention, the pattern blocks on tread one present different angles, and the angle changes from the center to the sidewall area as the position of the pattern blocks on the tread blocks changes, and the angle of the pattern blocks on tread two is positively correlated with the angle of the pattern blocks on tread one.

[0016] According to the studded tire provided by the present invention, the longitudinal pattern is continuous, and the tread crown connects two adjacent transverse patterns through the longitudinal pattern.

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Combine the following Figure 1 to Figure 6 Describe the present invention and the specific embodiments of the present invention: The present invention provides a studded tire, which is used on icy and snowy roads to increase the tire's grip while protecting the roadside to the greatest extent. The studded tire includes a tire body in the prior art, a tread crown, a sidewall, a bead fixed to a rim, and a nail hole 1 for anti-skid, and also includes a transverse pattern 2, a longitudinal pattern 4, a steel plate group, and anti-skid nails 9 opened or set on the tire. Figure 1 As shown, The transverse pattern 2 is arranged on the tire crown and is designed in an "eight" shape. The transverse pattern 2 divides the tire crown into a plurality of longitudinal tire blocks 3 of similar or identical shape. The side edges of the tire blocks 3 extend to the sidewalls to form a plurality of non-through inner grooves. The longitudinal patterns 4 are arranged on several divided tire blocks 3, one of which divides the tire block 3 where it is located into tread one 5 and tread two 6, and the shapes of tread one 5 and tread two 6 are different; the remaining longitudinal patterns 4 divide the tread one 5 or tread two 6 where they are located into several pattern blocks 7, each pattern block 7 is provided with several sipes 8, and the shapes of each pattern block 7 and the sipes 8 are also different.

[0023] The steel plate group includes several steel plates of different specifications, which are inserted into the inside of the knife groove 8. The knife grooves 8 in different directions have different steel plates inserted therein, but they follow the rules of adapting the shape, length or depth of the knife groove 8. The purpose is to improve the tire's grip while also improving the tire's rigidity.

[0024] Then, the anti-skid spikes 9 are arranged inside the spike holes 1, and the number of the anti-skid spikes 9 on each tire is not less than a predetermined number, which is finally determined based on the defects in the prior art, reference to relevant standards and research and development results.

[0025] Therefore, the beneficial effect of this embodiment is that the tire's grip can be improved through the transverse pattern 2, the longitudinal pattern 4 and the tread 1 5 and the tread 2 6 formed by the division thereof, and the wear of the tire on the ground can be reduced through the steel plate group and the anti-skid nails 9, thereby solving the problem in the prior art that the tire has weak grip and the tire has greater wear than the bottom surface.

[0026] In order to further explain the technical effect of the present invention in the above embodiment, the present invention also provides an additional embodiment. In this embodiment, based on the previous embodiment, this embodiment also defines the technical features of the previous embodiment. Specifically, in this embodiment, the longitudinal pattern 4 is through, and the crown connects two adjacent transverse patterns 2 through the longitudinal pattern 4, which is more convenient for rain and snow to be discharged. In addition, the angles of the pattern blocks 7 are different. Please refer to the attached manual. Figure 2 On the tire block 3 divided by the transverse pattern 2, the top center position of each tire block 3 is taken as the origin, the angle closest to the outer edge of each pattern block 7 is the first angle side, and the vertical axis of the origin is the second angle side. The first angle side, the second angle side, and the origin form an angle. For the convenience of understanding and explanation (the same below), in this embodiment, we define the angle formed on the tread 1 5 as angle α, and the angle formed on the tread 2 6 as angle β. Then, as shown in the figure, the angle will change with the position of the pattern block 7 on the tire block 3. Since the tire block 3 is in the shape of an "eight", the angle α and the angle β will gradually increase from the inner axis to the outer edge. Preferably, this change follows the following rules: 30°≤angle α≤60°; 30°≤angle α≤80°; angle β=α+k (k is ±20°); In addition, the tire further comprises a reinforcing rib 10, which is arranged in the transverse pattern 2 and is used to increase the rigidity of the pattern block 7. The reinforcing rib 10 changes with the angle of the pattern block 7. Figure 3 As shown, FD is the height of the tread block 3, and H1 is the height of the reinforcing rib 10. After precise calculation and research and development, we have determined that the value range of H1 is preferably (1 / 3FD-3 / 4FD). In this way, the stiffness of the pattern block 7 can be enhanced to the greatest extent by the reinforcing rib 10.

[0027] At the same time, in order to further improve the tire grip and the tire rigidity, the present invention further provides a steel sheet group, in which a plurality of steel sheets of different specifications are provided. In this embodiment, preferably, four groups of steel sheets are provided, as shown in the attached Figure 2 and Figure 4As shown, these steel sheets are arranged parallel to the edge of the pattern block 7, and they are steel sheet A, steel sheet B, steel sheet C and steel sheet D, wherein steel sheet A is inserted in the slit 8 of the tread 1 5 close to the tread 2 6, that is, the middle part of the entire tread block 3; and steel sheet B is inserted in the slit 8 of the tread 2 6 close to the tread 1 5, that is, the middle part of the entire tread block 3. Steel sheet A and steel sheet B are close to each other, and their arrangement and length change with the change of the length or angle of tread 1 5 and tread 2 6; and steel sheet C is inserted in the slit 8 next to steel sheet A and / or steel sheet B. Therefore, in the middle part of tread 1 5, the steel sheet with a length of more than 12 mm is steel sheet C, and the rest (length ≤ 12 mm) are steel sheet A and / or steel sheet B; steel sheet D is arranged at one end of the tread 1 5 and tread 2 6, that is, the two sides of the entire tread block 3; and as shown in FIG. Figure 2 As shown, steel sheet C is parallel to steel sheet A and steel sheet B respectively, while steel sheet D intersects with steel sheet A, steel sheet B, and steel sheet C on their extension lines respectively, thus forming a special arrangement layout.

[0028] Furthermore, in order to adapt the shape and depth of the sipe 8 and the overall layout of the tire, in a preferred embodiment of the present invention, requirements are put forward for the styles of the steel sheet A, steel sheet B, steel sheet C and steel sheet D. Specifically, Figure 4 As shown, steel sheet A has heights H2 and H3, steel sheet B has heights H2 and H4, steel sheet C has heights H2, H3 and H4, steel sheet D has heights H5, H6 and H7, and, preferably, in this solution: H3=(1 / 4H2-1 / 2H2); H4=(1 / 2H2-2 / 3H2); H6=(1 / 2H5-2 / 4H5); H7=(1 / 6H5-1 / 3H5).

[0029] Then comes the arrangement of the nail holes 1 on the crown. The number of nail holes 1 and anti-skid spikes 9 is not less than a predetermined number. In combination with relevant standards, certifications and research and development, in the preferred embodiment, this predetermined number is 100. That is to say, the tire manufactured in accordance with this embodiment has no less than 100 nail holes 1 and anti-skid spikes 9. Specifically, the anti-skid spikes 9 are embedded in the nail holes 1. The nail holes 1 are equally spaced on the crown of the tire. When the positions of the equally spaced nail holes 1 encounter the transverse pattern 2 or the longitudinal pattern 4, they are horizontally moved to the nearby contactable surface; when the patterns of the nail holes 1 and the crown overlap, the nail holes 1 cover the original pattern of the crown; when the aperture of the nail hole 1 protrudes from the pattern block 7, the protruding part is filled according to the aperture of the nail hole 1, or the size of the protruding nail hole 1 is adjusted according to the actual situation.

[0030] According to the arrangement of the nail holes 1, the present embodiment further provides a pattern layer 11 around the nail holes 1, and the pattern layer 11 is used to fill and adjust the position of the anti-slip nails 9. Specifically, in a preferred embodiment of the present invention, the pattern layer 11 is provided in 2 to 7 different sizes. Each pattern layer 11 is divided into a decorative area and an embedded hole area. The decorative area and the embedded hole area together form a circle, and the radius of the circle is 3 mm to 10 mm.

[0031] Remove the embedded hole area, and the decorative area is in the shape of a ring, on which a decorative part 12 is provided. The inner and outer ring diameters m1 of the decorative area are consistent with the height of the tire surface, and the height m2 of the decorative part 12 is 0.2mm-1.5mm lower than the tire surface. When the area covered by the embedded hole area exceeds the limit of the pattern block 7 and cannot be arranged, the pattern block 7 needs to be offset. Figure 5 As shown, in this embodiment, preferably, the distance W of the pattern block 7 offset in the groove direction is not greater than 2 mm, and the outermost boundary after offset is kept parallel to the boundary line of the original pattern block 7.

[0032] In general, if Figure 5 As shown, the value range of h is (0.2mm-1.5mm); the distance between m2 and m1 is not greater than 1.5mm, and the distance between the decorative part 12 and m2 except m2 and m1 is not greater than 1.5mm, so as to ensure that the pattern layer 11 fills and adjusts the position of the anti-skid nail 9 to meet the following requirements: the nail body of the anti-skid nail 9 is below the radial side surface of the tire, and the nail core protrudes from the tire surface to reduce the damage of the anti-skid nail 9 to the road surface.

[0033] In summary, the studded tire produced according to the present invention has at least the following advantages: The different textures on the tread of the tire are composed of the transverse pattern 2, the longitudinal pattern 4, the tread one 4, the tread two 6, the pattern block 7, etc. These textures maintain a suitable distance from the anti-skid studs 9, which can prevent the anti-skid studs 9 from falling off and can also maximize the grip.

[0034] The number of nail holes in the 205 / 55R16 test tire prepared according to the present invention is 252, and the test tire has passed the over run certification of the Finnish Transport Agency. According to the test method specified in TRAFICOM / 270676, the final result obtained is 0.98g (regulatory value 1.1g). Passing the over run certification of the Finnish Transport Agency can achieve a good balance between bottom wear and grip.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
