[0001] The utility model relates to the technical field of tire manufacturing, in particular to a steel rim curve structure of a low-section tire and the tire. Background Art
[0002] Tire vulcanization involves the chemical crosslinking of raw rubber using vulcanizing agents and accelerators under high temperature and pressure, forming a rubber network structure with practical value. This step not only improves the rubber's physical and mechanical properties but also imparts the desired elasticity, wear resistance, and safety to the tire, making it an essential step in tire production.
[0003] The curved steel rim structure of ordinary tires is very prone to rubber extrusion at the tip during tire vulcanization, causing deformation and risk of air leakage during subsequent use of the tire. Utility Model Content
[0004] The utility model provides a steel rim curve structure of a low-section tire and a tire in order to overcome the problem that the tip position of the tire is easily squeezed and deformed during vulcanization, which causes the risk of air leakage during subsequent use of the tire.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a steel rim curve structure for a low-section tire, characterized in that it includes a steel rim portion, wherein the steel rim portion is provided with an upper steel rim curve, a steel rim arc, a lower steel rim straight line and a lower steel rim curve from top to bottom, the steel rim arc, the lower steel rim straight line and the lower steel rim curve together constitute a sub-mouth, one end of the upper steel rim curve is connected to one end of the steel rim arc, the other end of the steel rim arc is connected to one end of the lower steel rim straight line, the other end of the lower steel rim straight line is extended with a lower steel rim curve, the angle formed by the lower steel rim straight line and the vertical line is d, and d is 5°-10°.
[0006] In the steel rim curve structure of the low-section tire as described above, the d is 5°.
[0007] In the steel rim curve structure of the low-section tire as described above, the radius of the upper steel rim curve is A, where A>10mm.
[0008] In the steel rim curve structure of the low-section tire as described above, A=17.9545 mm.
[0009] In the steel rim curve structure of the low-section tire as described above, the radius of the steel rim arc is B, where B>10mm.
[0010] In the steel rim curve structure of the low-section tire as described above, B=18 mm.
[0011] In the rim curve structure of the low-section tire as described above, the radius C of the lower rim curve is 5.5 mm.
[0012] A tire includes a steel rim curve structure of a low-section tire.
[0013] The tire as described above includes a tire portion, wherein the tire portion includes a tread portion and a side plate portion, an upper parting line is connected between the tread portion and the side plate portion, and the side plate portion is connected to the rim portion.
[0014] Compared with the existing technology, the beneficial effects of this technical solution are:
[0015] After adopting the structure of the utility model, in this application, the angle formed by the lower steel rim straight line and the vertical line is d, and the d is 5°-10°. The lower steel rim straight line is set to be inclined, so that the rubber on the side of the tire steel rim becomes thicker. The set inclination angle can also increase the space for storing rubber between the mold and the steel rim, thereby avoiding the deformation of the sub-mouth caused by overlapping and squeezing of rubber due to the small space for storing rubber.
[0016] Additional aspects and advantages of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS
[0017] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative labor.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.
[0021] like Figures 1 to 2As shown, a steel rim curve structure of a low-section tire includes a steel rim portion 1, wherein the steel rim portion 1 is provided with an upper steel rim curve 11, a steel rim arc 12, a lower steel rim straight line 13 and a lower steel rim curve 14 from top to bottom. The steel rim arc 12, the lower steel rim straight line 13 and the lower steel rim curve 14 together constitute a sub-mouth 3, one end of the upper steel rim curve 11 is connected to one end of the steel rim arc 12, the other end of the steel rim arc 12 is connected to one end of the lower steel rim straight line 13, and the other end of the lower steel rim straight line 13 is extended with the lower steel rim curve 14. The angle formed by the lower steel rim straight line 13 and the vertical line is d, and d is 5°-10°, preferably d=5°. After adopting the structure of the utility model, in this application, the angle formed by the lower steel rim straight line and the vertical line is d, and d is 5°-10°. The lower steel rim straight line is tilted, so that the rubber on the side of the tire steel rim becomes thicker. The set tilt angle can also increase the space for storing rubber between the mold and the steel rim, thereby avoiding the deformation of the sub-mouth due to overlapping and squeezing of rubber due to the small space for storing rubber.
[0022] Furthermore, to ensure a tight fit between the tire and the rim, the radius of the upper rim curve 11 is A, where A > 10 mm. Preferably, the radius of the upper rim curve 11 is A = 17.9545 mm. A larger radius ensures a tight fit between the tire and the rim when mounted, reducing tire swing during driving and improving safety. Furthermore, a larger radius helps disperse impact forces when the tire contacts the ground, reducing wear. The larger the radius of the upper rim curve 11, the more gradual the curvature, making it less likely that the rubber will be squeezed during tire production, and the tire will be less likely to deform.
[0023] As a specific embodiment, not a limitation, the radius of the steel rim arc 12 is B, where B>10mm. Preferably, the radius B of the steel rim arc 12 is 18mm. Similarly, to match the radius of the steel rim curve 11, the radius of the steel rim arc 12 is set larger. The gentler the curvature, the less likely the steel rim will squeeze the rubber during tire manufacturing, causing rubber deformation and affecting performance.
[0024] Furthermore, in this embodiment, the radius of the lower steel ring curve 14 is 5.5 mm.
[0025] As a specific embodiment, but not limiting, the tire comprises a tire portion 2, comprising a tread portion 21 and side panels 22. An upper parting line 23 connects the tread portion 21 and the side panels 22. The side panels 22 are connected to the rim portion 1. The tread portion 21 is provided on the tread to increase friction between the tread and the road surface, ensuring good contact between the tire and the road surface and preventing the vehicle from slipping during driving. The side panels 22 help support the tire shape and maintain tire stability. The upper parting line 23 and the side panels 22 connecting the tread portion 21 and the side panels 22 help improve the overall strength of the tire, thereby extending the tire's service life.
[0026] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
