Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire inspection technology, specifically a tire that can distinguish the degree of wear. Background Technology
[0002] Tire wear is a key indicator affecting tire life and safety performance. As tires wear down, their traction on wet roads decreases, impacting driver and vehicle safety. Furthermore, the current tire industry standard specifies a minimum tread depth of 1.6 mm.
[0003] Although this wear indicator specifies the minimum wear groove depth, it is located at the bottom of the tire groove and is poorly visible. Furthermore, this type of wear indicator does not allow drivers to identify uneven tire wear or abnormal wear.
[0004] An existing patent (authorization announcement number: CN219821126U) discloses a tire with observable wear levels. The key technical point of the solution is that during tire use, the markings start from the outermost mark and gradually disappear as the tire wears down. Users can use the remaining markings to check in real time whether the tire wear level is within a safe range. When the tire wear is close to the last marking or there are no markings left on the tire sidewall, users can intuitively confirm that the tire needs to be replaced. This allows the tire wear level to be presented to the user in a visual way, avoiding misjudgment and reducing the risk of use.
[0005] However, the above-mentioned technical solutions still have certain shortcomings. The existing TWI tire wear indicator can only indicate whether the tire tread grooves have reached their limit, and cannot intuitively indicate the wear progress of the tire, let alone indicate uneven tire wear. Moreover, uneven tire wear is very likely to occur in actual use, and the existing wear indicators alone cannot determine whether the tire has experienced uneven wear. Therefore, a tire that can distinguish the degree of wear is proposed. Utility Model Content
[0006] The purpose of this invention is to provide a tire that can distinguish the degree of wear, so as to solve the problems in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A tire capable of distinguishing wear levels includes a rim, tread pattern, tread area, groove area, and wear indicator. The tread area of the tire is provided with a wear pattern located at the edge of the longitudinal groove, and the total depth FD of the wear pattern is the same as the tire groove depth.
[0009] The wear pattern is divided into multiple equal layers along the depth direction to visually represent the wear progress of the tire.
[0010] The wear pattern is arranged around the entire circumference of the tire.
[0011] Based on the above technical solutions, this utility model also provides the following optional technical solutions:
[0012] In one alternative: the wear pattern is divided into four equal parts along the depth direction, corresponding to 1 / 4, 1 / 2, 3 / 4 and the full depth FD of the total depth FD, respectively.
[0013] In one alternative: the wheel hub side is provided with a disassembly assembly, which consists of an inner ring and an outer ring; the outer ring includes an outer hub body, a spring fixedly installed on the inner wall of the outer hub body, a locking block fixedly connected to one end of the spring, and a drive rod fixedly connected to one side of the locking block.
[0014] In one alternative: the wear pattern is composed of rubber layers of different depths, and the wear markings correspond to a first rubber block, a second rubber block, a third rubber block, and a fourth rubber block, and the four sets of rubber blocks correspond to 1 / 4, 1 / 2, 3 / 4 and full depth FD of the total depth FD, respectively.
[0015] In one alternative, the depth fraction of the wear pattern can be increased as needed to achieve a more accurate assessment of tire wear.
[0016] In one alternative: the wear pattern is located on the tire sidewall, with a symmetrical design of the upper and lower molds.
[0017] In one alternative: the wear indicator is divided into 6 equal parts along the tire circumference and used in conjunction with the wear pattern.
[0018] In one alternative: the total depth of the wear pattern is the same as the tire groove depth.
[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0020] 1. This utility model adds a tread pattern that represents the degree of wear to the entire tire surface. This wear pattern presents different depths on different surfaces, but does not affect the tire's performance.
[0021] 2. This utility model, through the displayed tire wear pattern, not only shows the tire wear condition but also allows for comparison of wear patterns in different locations to determine if abnormal tire wear has occurred. This reminds drivers to maintain their vehicles or tires in a timely manner, reducing the occurrence of accidents caused by poor tire wear. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0033] In one embodiment, such as Figures 1-6 As shown, a tire capable of distinguishing wear levels includes a rim 1, a tread pattern 3, a tread area 4, a groove area 5, and a wear indicator 6. The rim 1 has a disassembly assembly 2 on its side, which consists of an inner ring 22 and an outer ring 21. The outer ring 21 includes an outer rim body 211, a spring 212 fixedly installed on the inner wall of the outer rim body 211, a locking block 213 fixedly connected to one end of the spring 212, and a drive rod 214 fixedly connected to one side of the locking block 213.
[0034] In this embodiment, the markings for the groove area 5 and the tread area 4 are independently designed to identify uneven wear and assist in vehicle maintenance and diagnosis. At the same time, the spring 212 can be compressed by pressing the drive rod 214, thereby causing the locking block 213 to disengage from the locking groove of the inner ring 22 of the wheel hub 1. At this time, the outer ring 21 can be rotated off without tools. The preload of the spring 212 ensures that the locking block 213 will not accidentally come off during driving vibrations. Furthermore, the outer ring 21 (including the tread) and the inner ring 22 are designed to be separable, allowing for the replacement of the tread or wheel hub 1 components separately, reducing replacement costs (e.g., off-road vehicles can quickly switch between snow / road tire treads).
[0035] In one embodiment, such as Figure 5 and Figure 6 As shown, the tire tread area 4 is provided with a wear pattern. The wear pattern is located at the edge of the longitudinal groove, and its total depth FD is the same as the tire groove depth. The wear pattern is divided into multiple equal layers along the depth direction to visually represent the tire's wear progress. The wear pattern is arranged around the entire circumference of the tire. By comparing the wear degree of the wear pattern at different positions, it can be determined whether the tire has experienced uneven wear or abnormal wear. The total depth FD of the wear pattern is strictly consistent with the tire's longitudinal groove depth to ensure that the wear indication is completely synchronized with the actual tire life. When the outermost layer of the pattern disappears, it indicates that the tire has reached the legal minimum groove depth (usually 1.6mm) and needs to be replaced immediately.
[0036] As a supplement: the wear pattern is arranged continuously along the 360° circumference of the tire. By comparing the wear difference of the pattern at different positions, it is possible to identify: uneven wear (such as the inner pattern wearing faster than the outer pattern, which indicates inaccurate positioning or suspension problems); irregular wear (such as abnormal missing parts of the pattern, which indicates dynamic balance failure or brake system failure).
[0037] In one embodiment, such as Figure 6 As shown, the wear pattern is divided into four equal parts along the depth direction, corresponding to 1 / 4, 1 / 2, 3 / 4 and full depth FD of the total depth FD, respectively. The wear pattern is composed of rubber layers of different depths. The wear mark 6 corresponds to the first rubber block 61, the second rubber block 62, the third rubber block 63 and the fourth rubber block 64, and the four groups of rubber blocks correspond to 1 / 4, 1 / 2, 3 / 4 and full depth FD of the total depth FD, respectively. Through the four equal division nodes of 1 / 4FD, 1 / 2FD, 3 / 4FD and FD, the tire life is divided into four clear usage stages. Each stage corresponds to the wear exposure of a specific rubber block: the first rubber block 61 (1 / 4FD) disappears: indicating that 25% of the wear cycle has been completed, it is recommended to check driving habits or road conditions. The third rubber block 63 (3 / 4FD) is exposed: indicating that 25% of the service life remains, and replacement needs to be prepared.
[0038] In one embodiment, such as Figure 4As shown, the depth fraction of the wear pattern can be increased as needed to achieve a more accurate assessment of tire wear. The wear pattern is located on the tire sidewall and features a symmetrical upper and lower mold design. It is used to determine whether the tire is experiencing uneven or abnormal wear by comparing the differences in wear patterns in the left-right or up-down directions. Left-right comparison: diagnoses abnormal four-wheel alignment; up-down comparison: identifies crown wear caused by abnormal tire pressure. Drivers can determine the tire's wear condition and identify any abnormal wear by comparing wear patterns at different locations on the same tire. Similarly, the wear condition of different tires can be assessed to determine if vehicle adjustments are needed.
[0039] In one embodiment, such as Figure 6 As shown, the wear indicator 6 is divided into 6 equal parts along the tire circumference and used in conjunction with the wear pattern to enhance the visualization of tire wear. The appearance of the wear pattern gradually changes with the degree of tire wear. When the wear pattern wears down to the wear indicator 6 at the bottom of the groove, it indicates that the tire needs to be replaced. The tire circumference is divided into 6 60° sector areas (each sector corresponds to an arc length of approximately 42cm). Each sector area is independently equipped with a wear pattern and indicator to accurately identify abnormal wear areas on one side. The dynamic balance is determined by comparing the wear amount in the 6 sectors.
[0040] The above embodiments disclose a tire that can distinguish the degree of wear. By comparing the wear degree of wear patterns at different locations, it can determine whether the tire has experienced uneven wear or abnormal wear, and divide the tire life into four distinct usage stages. Each stage corresponds to the wear exposure of a specific rubber block, enabling real-time monitoring of tire life and usage.
[0041] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
