Description

Technical Field

[0001] This utility model belongs to the field of tracked wheel rim technology, specifically relating to a tracked wheel rim with automatic adjustable spacing. Background Technology

[0002] In today's booming automotive industry, wheels, as a crucial component for vehicle operation, directly impact driving safety and the driving experience. The rim, as a core component of the wheel structure, plays a vital role in the entire wheel system. It not only bears the weight of the tire but also serves as a vital bridge connecting the tire and the axle, significantly influencing the overall performance and fit of the tire. A well-designed, high-quality rim can effectively improve tire grip, stability, and comfort, providing a solid guarantee for vehicle driving safety. Given the wide variety of tire widths currently on the market, with significant differences in width between different tire specifications to meet the needs of various vehicle models and usage scenarios, width testing is particularly important to ensure a high degree of uniformity and accuracy in tire production specifications. Precise width testing ensures that every tire meets design standards, thereby achieving optimal performance under various road conditions and avoiding safety hazards caused by width mismatches, such as air leaks and uneven wear due to tire-rim mismatch. Currently, the industry commonly uses rim profile testing for tire width inspection. The specific procedure involves selecting a rim of the appropriate size from a series of rims of different widths based on the tire's preset width. The tire is then fitted onto this rim for a matching test. By observing the fit between the tire and the rim and checking for any gaps, the system determines whether the tire's width meets the requirements. This testing method, to a certain extent, meets basic testing needs and provides an important quality control tool for tire production.

[0003] However, this traditional inspection method has many drawbacks in practice and is quite cumbersome. Whenever tires of different widths need to be inspected, workers must manually change the rims to the corresponding widths. This process not only consumes a significant amount of time for disassembling and installing the rims but also requires substantial manpower. Furthermore, frequent rim changes can lead to a series of potential problems. Due to human error and wear and deformation that may occur during repeated disassembly and assembly, the inspection accuracy can easily decrease, making it impossible to accurately determine whether the tire width truly meets the standards, thus affecting the overall quality and safety of the tire. Therefore, how to improve tire width inspection methods and increase inspection efficiency and accuracy has become a crucial issue that the tire industry urgently needs to address. Utility Model Content

[0004] The purpose of this invention is to provide an automatically adjustable wagon rim to solve the problem of the limitations of existing wagon rims mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatically adjustable wheel rim, which includes a rim one, a rim two, a cylinder, and a limiting component; An adjustment assembly is provided between the first wheel rim and the second wheel rim, the adjustment assembly consisting of an alignment member and a connector; The alignment member is fixed to the inner wall of rim one, while the plug-in member is fixed to the inner wall of rim two, and the plug-in member movably passes through the inner side of the alignment member. The cylinder is fixed to the outer end of the second rim, and the cylinder drives the second rim away from or closer to the first rim; The limiting component is located on the inner side of the rim. The end of the limiting component is rotated and inserted into the inner side of the connector to limit the connector and prevent the connector from separating from the alignment component.

[0006] Preferably, the alignment member includes at least two parallel inner reinforcing rings, and an alignment groove is formed on the surface of each inner reinforcing ring.

[0007] Preferably, the inner wall of the second rim is fixed with an annular partition structure identical to the inner reinforcing ring, and an arc plate is fixed on the annular partition structure. The arc plate passes through the alignment groove. Through the connection between the arc plate and the alignment groove, the connection between the first rim and the second rim can be realized. When the second rim is moved, the distance between the first rim and the second rim can be adjusted, and it can also be ensured that the two will not separate.

[0008] Preferably, the limiting component includes a connecting plate, an adjusting ring, and a limiting plate; The adjusting ring is disposed on the outer surface of the outermost inner reinforcing ring of the rim; The connecting plate is fixed on the adjusting ring, and the limiting plate is fixed on the side of the connecting plate. The limiting plate is inserted into the inner side of the arc plate.

[0009] Preferably, one side of the arc plate is provided with a limiting groove for the insertion of the limiting plate, and each connecting plate is located between two adjacent arc plates.

[0010] Preferably, the adjusting ring and the arc plate do not contact each other, and the inner diameter of the adjusting ring is equal to the inner diameter of the inner reinforcing ring.

[0011] Preferably, at least two of the connecting plates have through holes on their surfaces, into which bolts are screwed (not shown). The inner reinforcing ring also has an arc-shaped hole for the bolt to pass through. During installation, the bolt is first inserted into the alignment groove from the inside until it passes through the through hole. Then, the nut is placed on the through hole. After the limiting groove passes through the alignment groove, the adjusting ring is rotated to make the limiting plate engage in the limiting groove. The nut is then tightened. At this time, the limiting plate can limit the limiting groove, preventing the limiting groove from accidentally disengaging. When separating, the nut is loosened, and the adjusting ring is rotated to remove the limiting plate from the limiting groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This invention transforms the original one-piece sliding rim into a two-part structure with movable left and right sides, and adds an adjustment component. This component automatically drives the left and right rims to adjust their width according to the actual width of the tire being inspected. This design not only retains the accuracy of sliding rim inspection but also achieves rapid, stepless adjustment of the inspection width, eliminating the need for frequent manual rim replacements. In practical applications, operators only need to input the tire width parameters to automatically adjust the rim spacing, greatly simplifying the inspection process and improving inspection efficiency and accuracy. It provides a more flexible and efficient solution for tire width inspection, demonstrating significant application value and promising prospects in both large-scale tire production lines and small tire inspection workshops.
