Description

Technical Field

[0001] This utility model relates to the field of wheel testing technology, and more specifically, to a shock absorption component for wheel impact testing. Background Technology

[0002] In the field of wheel impact testing, the damping performance and installation compatibility of testing equipment directly affect data accuracy. In existing technologies, traditional damping components often employ a fixed outer diameter structure, requiring disassembly of wheel components or forced embedding during installation, resulting in low installation efficiency and potential damage to the wheel's inner wall. Furthermore, damping mechanisms are mostly fixed springs, unable to adjust tension according to wheel size, leading to uneven impact energy absorption and often causing wheel deformation errors exceeding 1mm, resulting in poor test data repeatability. In addition, the integrated design of traditional components necessitates complete replacement for maintenance, resulting in high component costs and time-consuming processes. This invention effectively solves the problems of inconvenient installation, low damping efficiency, and high maintenance costs in existing technologies through an adjustable outer diameter radial connection structure, a dynamic tension return spring, and a modular component design, thereby improving the reliability and economy of wheel impact testing. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a shock-absorbing component for wheel impact testing, including a connecting column and a connecting flange installed at the end of the connecting column. Several radially arranged connecting tubes are installed on the outer wall of the connecting column in the axial direction. A movable connecting rod is inserted inside the connecting tube. An arc-shaped component that fits against the wheel is installed at the other end of the connecting rod. A movable moving component is sleeved on the outside of the connecting tube. A thread is opened on the outer wall of the connecting tube to cooperate with the moving component. The moving component moves outside the connecting tube through the thread. A return spring sleeved on the outside of the connecting rod is connected between the moving component and the connecting block.

[0004] In a preferred embodiment, the arc-shaped component includes a connecting block fixed to the end of the connecting rod away from the connecting post, and an arc-shaped plate is fixedly installed on the outer wall of the connecting block away from the connecting rod.

[0005] In a preferred embodiment, the movable component includes a spiral tube sleeved outside the connecting tube, the outer wall of the spiral tube being prismatic, a bearing being installed at the end of the spiral tube near the return spring, and a washer being installed at the end of the bearing near the return spring.

[0006] In a preferred embodiment, the inner ring of the bearing is fixedly connected to the screw tube, the outer ring of the bearing is fixedly connected to the washer, the bearing and the washer do not contact the outer wall of the connecting tube, and the end of the return spring away from the connecting block is fixed to the washer.

[0007] In a preferred embodiment, a through hole is provided on the side wall of the connecting pipe, which is aligned with the axis of the connecting pipe. The through hole penetrates the side wall of the connecting pipe, and a limit rod is inserted into the through hole. The limit rod is located inside the reset spring, and the other end of the limit rod is fixed to the connecting block.

[0008] The technical effects and advantages of this utility model are as follows:

[0009] 1. By rotating the prismatic solenoid tube, it moves on the thread on the outer wall of the connecting tube, causing the bearing and washer to move towards the connecting column. Then, the return spring pulls the arc-shaped part back, so that the outer diameter of the entire assembly can be reduced. This design makes it easy to install it inside the wheel during testing, and installation can be completed without complicated operations.

[0010] 2. After the component is installed on the wheel, rotating the solenoid in the opposite direction will allow the return spring to relax, causing the arc-shaped part to press against the inner wall of the wheel. In the impact test, the return spring can compress and deform to absorb the impact energy. Together with the limit rod sliding in the through hole of the connecting pipe, it restricts the movement trajectory of the connecting rod, ensuring that the arc-shaped part moves stably along the axial direction, effectively reducing the deformation error of the wheel caused by the impact, making the test process more stable and the data more reliable.

[0011] 3. The bearing design reduces friction between the solenoid and the washer, allowing the assembly to be adjusted repeatedly without failure. In addition, the prismatic solenoid outer wall facilitates manual force application. The overall structure is not only durable but also easy to operate. During maintenance, modular components can be disassembled individually, reducing maintenance costs. Attached Figure Description

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0017] like Figure 1-3 The shock-absorbing assembly shown includes a connecting column 1 and a connecting flange 2 installed at the end of the connecting column 1. Several radially arranged connecting pipes 3 are installed on the outer wall of the connecting column 1 in the axial direction. A movable connecting rod 4 is inserted inside the connecting pipe 3. An arc-shaped part that fits against the wheel is installed at the other end of the connecting rod 4. A movable moving part is sleeved on the outside of the connecting pipe 3. A thread 5 that mates with the moving part is opened on the outer wall of the connecting pipe 3. The moving part moves outside the connecting pipe 3 through the thread 5. A return spring 6 sleeved on the outside of the connecting rod 4 is connected between the moving part and the connecting block 7.

[0018] Based on the above, the arc-shaped part is used to fit inside the test wheel. When the moving part moves outside the connecting pipe 3 through the thread 5, it will pull the return spring 6 to move. When the moving part moves to the side of the connecting column 1, it will cause the arc-shaped part to shrink, making the outer diameter of the entire assembly smaller, which makes it easier to install inside the test wheel.

[0019] The arc-shaped component includes a connecting block 7 fixed to one end of the connecting rod 4 away from the connecting column 1, and an arc plate 8 is fixedly installed on the outer wall of the connecting block 7 away from the connecting rod 4;

[0020] The curved component fits into the wheel to withstand the impact load during the wheel impact test and transfer the impact energy to the connecting rod 4 and the return spring 6, while ensuring good contact between the component and the wheel and improving the stability of the test.

[0021] The movable component includes a screw tube 9 sleeved outside the connecting tube 3. The outer wall of the screw tube 9 is prismatic. A bearing 10 is installed at one end of the screw tube 9 near the return spring 6. A washer 11 is installed at the other end of the bearing 10 near the return spring 6. The inner ring of the bearing 10 is fixedly connected to the screw tube 9, and the outer ring of the bearing 10 is fixedly connected to the washer 11. The bearing 10 and the washer 11 do not contact the outer wall of the connecting tube 3. The end of the return spring 6 away from the connecting block 7 is fixed to the washer 11.

[0022] A through hole 12 is provided on the side wall of the connecting pipe 3, which is aligned with the axial direction of the connecting pipe 3. The through hole 12 penetrates the side wall of the connecting pipe 3. A limit rod 13 is inserted into the through hole 12. The limit rod 13 is located inside the reset spring 6. The other end of the limit rod 13 is fixed to the connecting block 7.

[0023] Based on the above, during use, the prismatic solenoid 9 is rotated, causing it to move along the thread 5 on the outer wall of the connecting tube 3 towards the connecting post 1, and the bearing 10 drives the washer 11 to move synchronously. The washer 11 pulls the return spring 6 to contract, which in turn drives the connecting rod 4 to retract towards the connecting post 1, causing the arc-shaped part to converge towards the center, reducing the outer diameter of the entire assembly, making it easier to insert into the installation space inside the wheel;

[0024] Furthermore, after the component is inserted into the wheel, the screw tube 9 is rotated in the opposite direction, the return spring 6 relaxes and pushes the arc-shaped component outward to press against the inner wall of the wheel. During the impact test, the impact force on the wheel is transmitted to the connecting rod 4 through the arc-shaped plate 8. The return spring 6 is compressed and deformed to absorb energy, while the limiting rod 13 slides in the through hole 12 of the connecting tube 3, restricting the movement trajectory of the connecting rod 4, ensuring that the arc-shaped component moves stably along the axial direction, avoiding radial offset, thereby reducing the deformation error of the wheel caused by the impact.

[0025] By adjusting the thread 5 of the solenoid 9, the outer diameter of the component can be quickly contracted and expanded to adapt to the inner diameter space of wheels of different sizes, and the installation efficiency is greatly improved compared with the traditional disassembly structure.

[0026] The curved design of the arc plate 8 fits tightly against the inner wall of the wheel, allowing for quick positioning without additional tools and reducing installation difficulty;

[0027] The cooperation between the return spring 6 and the limiting rod 13 enables the impact energy to be transmitted axially, effectively avoiding the deformation error of the wheel caused by uneven force during the impact test;

[0028] Limiting rod 13 restricts the radial movement of connecting rod 4, ensuring that the force direction is consistent in each impact test and improving data repeatability;

[0029] The bearing 10 is designed to enable frictionless relative rotation between the solenoid 9 and the washer 11. The component is repeatedly adjustable and suitable for high-frequency testing scenarios.

[0030] The outer wall design of the prismatic solenoid 9 facilitates manual force application, avoids slippage, and improves operational convenience.

[0031] Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
