Description

Technical Field

[0001] This solution relates to the field of wheel testing technology, and in particular to a wheel rim assembly testing device. Background Technology

[0002] In the bicycle manufacturing industry, the rim, as a core component, plays a decisive role in riding safety and comfort. During daily riding, the rim frequently withstands various complex external forces. First, when riding, the pedals drive the sprocket and chain, causing the wheel to rotate continuously, and the rim bears the torque generated by the wheel's rotation. This torque depends not only on the power transmitted by the chain but also on the rider's pedaling force and frequency. Second, when turning, avoiding obstacles, or riding on uneven surfaces, the rim experiences lateral pressure from different directions. When turning, the centrifugal force of the bicycle subjects the rim to outward lateral force; when encountering obstacles, the rim experiences instantaneous impact and lateral compression; when riding on uneven surfaces, the rim must cope with the irregular lateral forces generated by the road surface undulations. These complex and varied stress conditions place extremely high demands on the structural strength, stability, and durability of the rim.

[0003] Existing rim testing equipment generally has limitations, with most only capable of testing a single performance aspect of the rim. For example, some devices can only test the rim's static load-bearing capacity, simulating the rim's ability to bear the vehicle's weight when stationary, failing to reflect the rim's true performance during dynamic driving. Other devices can only detect the rim's performance under simple torque, considering only the torque factor and ignoring other complex stress conditions present during actual driving. These single-performance testing methods cannot meet the comprehensive testing needs for rim torque response displacement and lateral pressure deformation. This makes it difficult to comprehensively and accurately assess the actual performance of rims during rim development and quality inspection, potentially leading to undetected problems that could affect the overall performance and safety of the vehicle, creating hidden dangers for driving.

[0004] Therefore, there is a need for a rim testing device that can perform combined tests on rims and provide more comprehensive and accurate data support. Summary of the Invention

[0005] To address the aforementioned issues, this solution provides a wheel rim assembly testing device that can effectively and accurately test the wheel rim's response displacement under torque and its deformation under lateral pressure, thereby providing comprehensive and accurate data support for wheel rim research and development, quality inspection, and other related processes.

[0006] To achieve the above objectives, the technical solution adopted in this paper is: a wheel assembly testing device, comprising a testing unit supporting the top of the assembly, wherein the testing unit includes...

[0009] Distance measuring component, used to measure the displacement distance caused by torque;

[0013] Furthermore, at least two second limiting components are distributed along the edge of the support component, and the second limiting components also include an adjustment part.

[0014] Furthermore, the adjustment unit drives the fixed seat that is slidably connected to the slide rail.

[0015] Furthermore, the adjusting part includes an adjusting seat and a threaded adjusting rod, wherein the adjusting rod is threadedly engaged with the adjusting hole of the adjusting seat and is limited within the fixing groove of the fixing seat.

[0016] Furthermore, the upper end of the fixed base is provided with a first roller and a second roller. The first roller is in contact with the lower end surface of the wheel rim to limit axial displacement, and the second roller is provided on the side of the wheel rim as a guide wheel.

[0017] Furthermore, the ranging component and displacement display device are slidably connected to the ranging bracket via a sliding groove.

[0018] Furthermore, the displacement display device is a ruler with precise scale markings and an edge with an arc-shaped structure adapted to the wheel rim;

[0019] The pressure measuring assembly includes a pressure sensor on a pressure measuring bracket.

[0020] Furthermore, the support assembly includes a support frame at the bottom of the test bench, with casters connected to the bottom of the support frame.

[0034] The present solution will be further described below with reference to the accompanying drawings and embodiments:

[0035] Example 1:

[0036] A wheel assembly testing device, such as Figure 1-6 As shown, it includes a support component 100 and a test unit 200.

[0037] The support component 100 includes a support frame 120 at the bottom of the test bench 110. The bottom of the support frame 120 is connected to casters 121. The support component 100 provided in this solution is used to support the test unit 200 on the test bench 110. Combined with the casters 121, it is easy to move and suitable for different usage scenarios.

[0038] like Figure 1 and Figure 2 As shown, the test unit 200 includes a first limiting component 210, a second limiting component 220, a ranging component 230, and a pressure measuring component 240.

[0039] like Figure 1 and Figure 2 as well as Figure 3 As shown, the first limiting component 210 is used to limit the rim to be tested, and includes a torque sensor 211 and a limiting bracket 212. The torque sensor 211 is located at the center of the test bench 110, and the rim is placed on the torque sensor 211. The limiting bracket 212 is located above the torque sensor 211, and a limiting rod 2121 is connected to the middle of the limiting bracket 212. The top of the limiting rod 2121 is limited on the limiting bracket 212, and the bottom is inserted into and limits the rim.

[0040] Specifically, the rim is placed on the torque sensor 211, the limit rod 2121 is adjusted to limit the rim, and the rim is manually rotated. When the rim rotates due to torque, the torque sensor 211 can accurately measure the torque value generated during the rotation of the rim in real time and transmit the data to the subsequent data processing unit.

[0041] like Figure 1 and Figure 2 as well as Figure 4 As shown, at least two second limiting components 220 are provided on the test bench 110, including a first roller 222 and a second roller 223 vertically arranged on the upper end of a fixed base 221. The bottom of the fixed base 221 is slidably connected to a slide rail 224, and the back of the fixed base 221 is connected to an adjustment part 225.

[0042] The first roller 222 is in contact with the lower end face of the rim to limit the axial displacement of the tire, ensuring that the rim remains in an accurate position during testing, thereby greatly improving the accuracy of the test results. The second roller 223 is located on the side of the rim and acts as a guide wheel to guide the rim to maintain a stable direction during rotation, preventing directional deviation.

[0043] The adjusting part 225 has an adjusting seat 2251 fixed next to the slide rail 224. The adjusting rod 2252 is inserted into the adjusting hole of the adjusting seat 2251 and limited in the fixing groove 2211 of the fixing seat 221. The adjusting rod 2252 has threads and engages with the threads in the adjusting hole.

[0044] The adjusting rod 2252 has two disc-shaped ends, one end of which is limited in the fixing groove 2211, and the other end is used for manual rotation.

[0045] In this solution, the fixed seat 221 is adjustable to meet the testing requirements of different sizes of wheel rims, and has strong flexibility. Furthermore, by combining the first roller 222 and the second roller 223, the axial displacement of the wheel rim can be limited to prevent displacement of the wheel rim.

[0046] In this embodiment, three of the second limiting components 220 are provided.

[0047] Specifically, rotating the adjusting rod 2252 causes the fixed seat 221 to slide on the slide rail 224. Because the external thread of the adjusting rod 2252 engages with the internal thread of the adjusting hole, the fixed seat 221 can only slide by rotating. During the test, it is not easy to shake and is more stable.

[0048] like Figure 1 and Figure 2 as well as Figure 5 As shown, the ranging component 230 includes a displacement display device 231, which is limited within the sliding groove 2321 of the ranging bracket 232. The edge of the displacement display device 231 is arc-shaped and fits the edge of the wheel rim.

[0049] In this design, the displacement display device 231 is slidably connected to the ranging bracket 232, facilitating the replacement of the displacement display device 231 according to different wheel rim models, resulting in high replacement efficiency. The displacement display device 231 is a scale with precise graduation markings; the scale is low in cost and easy to read by the human eye.

[0050] Specifically, a clear graduation line is set around the edge of the bicycle rim. Aligning this graduation line with a scale, the operator observes the movement of the graduation line on the rim as it rotates under torque. During rotation, the graduation line on the rim and the scale on the fixed scale experience relative displacement. By reading the difference between the initial position of the graduation line on the rim and its position on the scale after rotation, the operator can accurately determine the rotation distance of the rim, which is the displacement of the rim under torque. To improve measurement accuracy, the scale on the fixed scale can be finely divided according to actual testing needs, such as to millimeters or even smaller units. Furthermore, a sight can be added to ensure that the operator can clearly and accurately observe the correspondence between the graduation line on the rim and the scale on the fixed scale from different testing angles, thus guaranteeing the accuracy of the displacement measurement.

[0051] like Figure 1 and Figure 2 as well as Figure 6 As shown, the pressure measuring assembly 240 includes a pressure sensor 242 on a pressure measuring bracket 241. When the bicycle rim is subjected to lateral pressure during rotation, the rim exerts a squeezing force on the bottom of the pressure sensor 242, which is transmitted to the pressure sensor 242. The pressure sensor 242 can measure the magnitude of the lateral pressure on the rim during rotation in real time and transmit this data to the data processing unit.

[0052] Further explanation based on its usage mechanism:

[0053] S1. Test Preparation

[0054] Place the rim on the torque sensor 211, adjust the limit rod 2121 to limit the rim, and adjust the fixing seat 221 to drive the first roller 222 and the second roller 223 to fit the rim.

[0055] S2, Response displacement caused by test torque

[0056] When the rim is manually rotated to one side, the torque sensor 211 can accurately measure the torque value generated during the rotation of the rim in real time and transmit the data to the subsequent data processing unit. The distance measuring component 230 records the distance the rim rotates.

[0057] S3, Deformation under lateral pressure test

[0058] An external force is applied to the wheel rim. When the rim is subjected to lateral pressure during rotation, it generates a squeezing force on the bottom of the pressure sensor 242, which is then transmitted to the pressure sensor 242. The pressure sensor 242 can measure the magnitude of the lateral pressure experienced by the rim during rotation in real time and transmit this data to the data processing unit.

[0059] In summary, the testing device provided in this application can simultaneously test the response displacement of the rim under torque and the deformation under lateral pressure, providing comprehensive and accurate data for the performance evaluation of the rim and helping to improve the R&D quality and manufacturing process level of the rim.

[0060] The testing device provided in this application has a reasonable structural design and a simple and easy-to-understand operation process. Operators can complete the test simply by rotating the wheel, which greatly improves the testing efficiency.

[0061] The testing device provided in this application can adapt to the testing needs of wheel rims of different sizes and specifications, and has strong versatility and adaptability.
