[0021] In order to make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0022] In one embodiment, as Figure 1 shown, a tire with a shoulder flower decoration design includes a tread crown 1, a tire shoulder 2, and a tire sidewall 3. The tread crown 1, the tire shoulder 2, and the tire sidewall 3 form the tread of the tire. The tread crown 1 is a surface perpendicular to the circular cross-section of the tire, the tire sidewall 3 is a surface parallel to the circular cross-section of the tire, the tire shoulder 2 is the connecting part between the tread crown 1 and the tire sidewall 3, and the tire shoulder 2 and the tire sidewall 3 are evenly distributed with shoulder flower decorations 301. Such shoulder flower decorations 301 have a thicker sidewall build-up rubber than that of ordinary tires, and can exhibit puncture resistance, tear resistance, enhance the driver's wild vision, and have a particularly unique shape under non-paved road conditions such as off-road driving.
[0023] In one embodiment, as Figure 1As shown, anti-slip grooves are provided on the tread of the tire. Both the grooves and the shoulder flower decoration 301 are formed by hot pressing the tire panel through a mold. The grooves and the shoulder flower decoration 301 are integrally formed to ensure the sealing of the tire.
[0024] In one embodiment, the tire panel is formed by extruding the shaped rubber through a die plate. The die plate can ensure the uniform extrusion thickness of the shaped rubber by adjusting the depth difference of the left and right processing of the rubber outlet.
[0025] In one embodiment, as Figure 2 and Figure 3 shown, the height of the shoulder flower decoration 301 is SH-1, the nominal broken height of the shoulder flower decoration 301 is SH, and the nominal broken width of the shoulder flower decoration 301 is SW, where SH-1 / SH = 0.26 - 0.33, SW / SH ≥ 0.6, and the nominal broken height SH is the difference between the inner diameter OD of the tire and the mating diameter RW of the mold.
[0026] In one embodiment, as Figure 2 and Figure 3 shown, the depth of the shoulder flower decoration 301 is 8.5 mm - 10.5 mm, which is suitable for the sidewall die design of SUV series tires that highlight the wild characteristics.
[0027] In one embodiment, as Figure 4 and Figure 5 shown, the area of the shoulder flower region on the die plate is S1, and the area of the shoulder flower region on the mold is S, where S1 / S = 80% - 135%. By adopting this design ratio, the risk of appearance defects such as concavities and bulges on the tire sidewall in the inflated state caused by deep grooves and high flat ratios in the shoulder flower decoration area can be effectively avoided.
[0028] The above embodiments disclose a tire with a shoulder flower decoration design. Generally, for the sidewall die design of products such as SUV, AT, XT, RT, MT series with a shoulder flower decoration area design, the theoretical calculation of the expansion ratio of different sidewall rubber materials at each point in the shoulder flower area is adopted. This design method has requirements for the thinnest rubber thickness in the shoulder flower decoration area according to different sales markets. The utility model controls the ratio between the area S1 of the shoulder flower region on the die plate and the area S of the shoulder flower region on the mold on the premise of ensuring that the semi-steel radial tires such as SUV, AT, XT, RT, MT with a shoulder flower decoration design meet the requirements for the thinnest rubber thickness in the shoulder flower decoration area in different sales markets, and solves the problem of appearance defects such as concavities and bulges on the tire sidewall in the inflated state for tires with a wild shape highlighted by the shoulder flower decoration design.
[0029] As described above, it is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
