Description

Technical Field

[0001] The utility model belongs to the technical field of tires, and in particular relates to a load-bearing tire with a sinking amount indicator. Background Art

[0002] Whether the vehicle is overloaded, deflated, or both, the tire will sink too much, which can easily lead to delamination, bulging, or even explosion, which not only affects the service life of the tire, but also affects the driving safety of the vehicle. When we judge the cause of tire failure, it is difficult to determine whether it is overloaded or deflated based on the tire's usage.

[0003] China Patent Publication No. CN102476565A_Named "Load-carrying tire indicating tire pressure and load status", the patent requires careful reading of the scale lines on the tire to infer whether the ratio of air pressure to load is appropriate. At the same time, the patent mark is concave, which cannot effectively reflect the phenomenon that the tire sinks a lot and is worn. Utility Model Content

[0004] In view of the deficiencies existing in the related art, the utility model provides a load-carrying tire with a sinking amount indicator, which solves the technical problem that when judging the sinking amount of the tire, it is difficult to read the scale lines on the tire carefully.

[0005] The utility model provides a load-carrying tire with a sinking amount indicator, comprising:

[0006] A plurality of identification groups, wherein the plurality of identification groups are distributed at certain intervals on the tire sidewall along the circumference of the tire, and each identification group further comprises:

[0007] The static load radius marking line is located at the outermost periphery of the plurality of marking groups and is a reference line for the standard tire sinking amount when the vehicle is stationary;

[0010] In other embodiments, the static load radius marking line is in a concave form.

[0011] In other solutions, the 10% sinkage marking line is in the form of a convex line or a concave line.

[0012] In other solutions, when the 10% sinking amount marking line is in the form of a convex line, the scale marking line is in the form of a convex line; when the 10% sinking amount marking line is in the form of a concave line, the scale marking line is in the form of a concave line.

[0013] In other embodiments, the marking group of the 10% sink mark line and the scale mark line in the form of the convex line is spaced apart from the marking group of the 10% sink mark line and the scale mark line in the form of the concave line.

[0014] In other embodiments, the plurality of identification groups total six groups, which are evenly distributed on the sidewall of the tire.

[0015] In other solutions, the scale marking lines include a long line and a plurality of short lines, the long line is close to the center of the sidewall circle, and the plurality of short lines are located outside the long line.

[0016] In other embodiments, the depression is formed by digging out a portion of the tire surface.

[0017] In other embodiments, the convex line is formed by adding a portion to the tire surface.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "up", "down", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0036] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] like Figure 1-4 , Figure 6 As shown, the utility model provides a load-carrying tire with a sinkage indication, comprising: a plurality of identification groups, which are distributed at certain intervals on the tire sidewall along the circumference of the tire, such as the first identification group 1, the second identification group 2, the third identification group 3, the fourth identification group 4, the fifth identification group 5, and the sixth identification group 6 in this embodiment, each identification group further comprises:

[0039] The static load radius marking line 7 is located at the outermost periphery of the plurality of marking groups and is a reference line for the standard tire sinking amount when the vehicle is stationary. It can be understood that the static load radius marking line 7 can be used as a reference line for the standard tire sinking amount when the vehicle is stationary, and the marking line is only used as a reference. The position of the static load radius marking line 7 is determined by the following formula, and this embodiment is described by taking a 205 / 55R16 tire as an example:

[0040] According to the formula, the theoretical static load radius Rs = dr / 2 + FR*(d-dr) / 2;

[0041] Where, dr: nominal rim diameter, d: tire design outer diameter, FR: coefficient 0.78;

[0042] Then for 205 / 55R16: Rs=406 / 2+0.78*(632-406) / 2=291.14≈291, that is, the distance between the static load radius marking line 7 and the center of the sidewall is 291 mm.

[0043] The 10% sinking amount marking line 8 is located inside the static load radius marking line 7 and is used as a reference / judgment of insufficient or overloaded tire pressure during vehicle use; it is understandable that the 10% sinking amount marking line 8 can be used to preliminarily determine tire sinking or tire pressure abnormalities due to other factors; in this embodiment, the 205 / 55R16 specification 10% sinking amount marking line position H=632 / 2*10%=31.6, rounded to 32mm; the position is determined to be 632 / 2-32=284 and is marked here.

[0044] The scale mark line 9 is located inside the 10% sink mark line 8 to determine whether the vehicle is under-inflated or overloaded. If the tire is running at low pressure or high load for a long time, when the scale mark line 9 is reached, the degree of tire deflation is determined according to the position of the scale mark line reached.

[0045] The load-carrying tire of the present invention has a sinkage indication, and the degree of tire deflation is determined by the 10% sinkage indication line and the scale indication line, based on the static load radius indication line as a reference.

[0046] like Figure 1-2 As shown, in other embodiments, the static load radius identification line 7 is in a concave form. It can be understood that in this embodiment, the line mainly has two forms, a concave form and a convex line form; among them, the advantage of the concave form is wear resistance, and the disadvantage is inconvenient observation and unclear indication; the advantage of the convex line form is convenient observation and clear indication, and the position where the convex line is worn is the tire sinking amount, and the disadvantage is that it is not wear-resistant and is easy to fall off from the tire surface after wear. Since the static load radius identification line 7 is a reference line, a concave line form is adopted.

[0047] like Figure 1-2 As shown, in other embodiments, the 10% sinking amount marking line 8 is in the form of a convex line or a concave line. It can be understood that the 10% sinking amount marking line 8 in the form of a concave line serves as a reference, and the 10% sinking amount marking line 8 in the form of a convex line serves as a judgment.

[0048] like Figure 1-2 As shown, in other embodiments, when the 10% sinking amount marking line 8 is in the form of a convex line, the scale marking line 9 is in the form of a convex line; when the 10% sinking amount marking line 8 is in the form of a concave, the scale marking line 9 is in the form of a concave. It can be understood that the forms of the static load radius marking line 7, the 10% sinking amount marking line 8, and the scale marking line 9 include two types, namely, concave form-concave form-concave form and concave form-convex line form-convex line form.

[0049] like Figure 5 As shown, the marking group with the 10% sinkage marking line and the scale marking line in the form of the convex line is spaced apart from the marking group with the 10% sinkage marking line and the scale marking line in the form of the concave line. For example, in this embodiment, the first marking group 1, the second marking group 3, and the third marking group 5 are in the form of a concave form-a concave form-a concave form, and the first marking group 2, the second marking group 4, and the third marking group 6 are in the form of a concave form-a convex line form-a convex line form. The staggered distribution of the two marking groups means that there are always reference lines and observation lines. And since there is the same group of marking lines on both sides of the tire, it is also possible to observe whether there is a problem of uneven wear of the tire during driving.

[0050] like Figure 6As shown, in the embodiment of the present scheme, the plurality of identification groups are six in total, evenly distributed on the sidewall of the tire. Six identification groups can be sufficient to observe the sinking situation. According to the actual situation of the tire, if the tire specification is larger, eight identification groups can also be set.

[0051] like Figure 1-2 As shown, in other embodiments, the scale marking line 9 includes a long line and a plurality of short lines, the long line is close to the center of the tire side circle, and the plurality of short lines are located outside the long line. The long line position indicates that the tire sinks severely.

[0052] like Figure 8 As shown, the concave form 11 is formed by digging out a part of the tire surface. The concave form 11 is not easy to wear off, but it is inconvenient to observe. If all lines are concave, it is easy to not know which line the sinking amount is.

[0053] like Fig. 9 As shown, the convex line form 12 is formed by adding a part to the tire surface. The convex line form 12 is easy to be worn away, but it is easy to observe the sinking amount. The place designated by the convex line form worn on the innermost side of the tire is determined as the tire sinking amount position.

[0054] like Figure 7 As shown, in other embodiments, the tire further includes: a usage instruction mark 10, which is located in the blank area of ​​the tire sidewall. The usage instruction mark 10 briefly records the usage of the tire.

[0055] Through the description of multiple embodiments of the load-carrying tire with sinkage indication of the utility model, it can be seen that the utility model has at least one or more of the following advantages:

[0056] 1. The utility model uses the static load radius marking line as a reference, and uses the 10% sinking amount marking line and the scale marking line to determine the degree of tire deflation;

[0057] 2. The utility model sets the lines in a concave form and a convex line form, the concave form is wear-resistant as a reference line, and the convex line form is not wear-resistant as a judgment line, so that the sinking amount of the tire can be accurately and conveniently observed.

[0058] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0059] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
