Description

Technical Field

[0001] The invention belongs to the technical field of vibration durability detection, and in particular relates to a vibration durability detection test bench of a straddling locomotive type. Background Art

[0002] With the rapid development of the motorcycle industry, the demand for durability testing of motorcycles and their components is also increasing. As an important equipment for evaluating the durability and reliability of motorcycles during long-term use, the vibration durability test bench plays an important role in the research and development and quality assurance of motorcycles.

[0003] The traditional vibration durability test bench is mainly composed of a front wheel limit assembly, a rear wheel limit assembly, a rotating mechanism, a test platform and other parts, which are used to simulate the vibrations that a motorcycle is subjected to during driving. For example, the fixing device and method of a motorcycle chassis vibration durability test bench fixture with the announcement number "CN117091786A" includes a front fixing assembly for clamping and fixing the handlebars of the motorcycle; a middle load assembly for applying a load along the gravity direction to the middle of the motorcycle to simulate the stress state of the motorcycle in the riding state; a rear wheel rolling wheel assembly for limiting the rear wheel of the motorcycle; a front drum rotating mechanism and a rear drum rotating mechanism for providing driving force for the rotation of the motorcycle wheel, and a plurality of special-shaped protrusions are arranged on the front drum rotating mechanism and the rear drum rotating mechanism, and the motorcycle wheel and the special-shaped protrusions can periodically contact so that the motorcycle can present an up and down vibration state, wherein the special-shaped protrusions are in an asymmetric state, and are composed of two curved surfaces with different radians. The special-shaped bumps can simulate the road conditions of motorcycle wheels climbing long and steep slopes, and can also simulate the road conditions of a vehicle bouncing up when it goes up steps from the ground.

[0004] However, it still has the following obvious defects during use: the front and rear wheel limit assemblies of the vibration durability test bench are usually fixed and cannot be adjusted according to different models of motorcycles. This means that the test bench is limited in its scope of application and can only test motorcycles of specific sizes and types. Since the front and rear wheel limits are fixed, the test bench cannot adapt to a variety of different models of motorcycles, especially when there are large differences in motorcycle size, front and rear wheel spacing, etc. This limits the versatility of the test bench in practical applications. In the prior art, in order to adapt to different models of motorcycles, it may be necessary to use multiple test benches with different configurations, which not only increases costs but also reduces test efficiency.

[0005] In view of this, a vibration durability test bench that can adjust the distance between the front and rear wheel limiter components is proposed to meet the test requirements of different types of motorcycles, which has become an important improvement direction of the existing technology. This improvement can improve the application scope, test accuracy and efficiency of the test bench, and provide a more accurate basis for motorcycle design and improvement. Summary of the invention

[0006] The present invention aims to solve the technical problem that the front and rear wheel limit assemblies of the vibration durability test bench in the above-mentioned prior art are usually fixed and cannot be adjusted according to different models of motorcycles, thus limiting the scope of application.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A vibration durability test bench for motorcycle-type, comprising a front wheel limit assembly, a rear wheel limit assembly, a translation mechanism, a front drum rotation mechanism and a rear drum rotation mechanism; a test platform, a base and a support rod constitute a test frame for installing the front wheel limit assembly, the rear wheel limit assembly, the translation mechanism, the front drum rotation mechanism and the rear drum rotation mechanism. The front drum rotation mechanism cooperates with the rear drum rotation mechanism to provide driving force for the rotation of the motorcycle wheel.

[0009] The front wheel limiting assembly is used to clamp and fix the front fork of the motorcycle, including two limiting plates for positioning the two sides of the front fork of the motorcycle and a rolling wheel for limiting the front wheel of the motorcycle;

[0010] The rear wheel limiting assembly is used to limit the rear wheel of the motorcycle;

[0011] The translation mechanism is used to drive the front wheel limit assembly and the front drum rotation mechanism to translate synchronously along the test platform to adjust the distance between the front wheel limit assembly and the rear wheel limit assembly, so as to perform vibration durability detection tests on different types of motorcycles.

[0012] The motorcycle is placed on the vibration durability test bench of the cross-motorcycle type. The front wheel limit assembly clamps the motorcycle front fork through two limit plates to ensure that the front wheel does not move; the rear wheel limit assembly limits the rear wheel of the motorcycle to ensure that the rear wheel remains stable. The translation mechanism drives the front wheel limit assembly and the front drum rotation mechanism to translate synchronously along the test platform to adjust the distance between the front wheel limit assembly and the rear wheel limit assembly. In this way, the actual distance of different types of motorcycles during driving can be simulated, providing accurate vibration durability tests for various motorcycles. The front drum rotation mechanism and the rear drum rotation mechanism drive the front and rear wheels of the motorcycle to rotate respectively, simulating the vibration of the motorcycle during driving. By adjusting the vibration frequency and amplitude, the vibration conditions under different road conditions can be simulated.

[0013] This cross-motorcycle vibration durability test bench can be applied to different types of motorcycles. By adjusting the distance between the front wheel limit assembly and the rear wheel limit assembly, it can meet the testing requirements of different models. The test bench can effectively fix the motorcycle to ensure that the motorcycle will not move accidentally during the test, reducing the test risk. By adjusting the vibration frequency and amplitude of the front drum rotating mechanism and the rear drum rotating mechanism, the vibration conditions under various road conditions can be simulated to make the test results more accurate. Through the vibration durability test, the durability and reliability of each component of the motorcycle during long-term use can be evaluated, providing a basis for motorcycle design and improvement.

[0014] Preferably, the front wheel limiting assembly comprises two vertical supports A connected by a connecting rod A, a connecting rod B connecting the top ends of the two vertical supports A, two connecting plates A rotatably connected to the two connecting rods B, and a connecting rod C connecting the two connecting plates A, wherein the two limiting plates are rotatably sleeved on the outer side surfaces at both ends of the connecting rod C and are located on the inner sides of the two connecting plates A;

[0015] The front wheel limit assembly also includes two horizontal plates that are fixed to the outside of the two vertical supports A by bolts. The two horizontal plates are symmetrically and evenly distributed with a number of straight notches. The bolts penetrate the straight notches to lock and fix the horizontal plates to the vertical supports A. The rolling wheels are rotatably arranged on the inner sides of the ends of the two horizontal plates. Through the combination of bolts and straight notches, the position of the limit plate can be easily adjusted to adapt to different sizes and types of motorcycle front wheels.

[0016] Preferably, the rear wheel limiting assembly includes two vertical supports B fixed on the top of the test platform, a connecting rod D connecting the two vertical supports B, two connecting plates B respectively located outside the two vertical supports B and locked on the outer side of the connecting rod D by a locking nut, a connecting rod E connecting the two connecting plates B, an I-shaped roller rotatably sleeved on the outer side of the connecting rod E and cooperating with the motorcycle rear wheel limiting, two fixed blocks A fixedly sleeved on the outer side of the connecting rod E and located on both sides of the I-shaped roller, and a limiting roller rotatably arranged on the two fixed blocks A and cooperating with both sides of the motorcycle rear wheel for limiting. The design of the I-shaped roller and the limiting roller can accurately limit the position of the rear wheel to ensure the accuracy of the test. Through the locking nut, the position of the I-shaped roller and the limiting roller can be quickly adjusted to adapt to motorcycle rear wheels of different sizes.

[0017] Preferably, the translation mechanism includes a servo screw linear module installed on the base, a translation support fixed on the moving slide of the servo screw linear module, a mobile platform A and a mobile platform B fixed on the top of the translation support and located on both sides of the front drum rotating mechanism, the mobile platform A and the mobile platform B are both located below the rectangular opening A on the test platform, one side of the mobile platform A is connected to a protective curtain A that cooperates with the guide sliding of the test platform, and one side of the mobile platform A is connected to a protective curtain B that cooperates with the guide sliding of the test platform;

[0018] The two vertical supports A on the front wheel limit assembly are fixedly mounted on the top of the mobile platform B;

[0019] The base and the test platform are connected via a number of support rods.

[0020] The servo screw linear module can realize precise translation control of the translation support, front wheel limit assembly and front drum rotation mechanism, ensuring that the test bench can accurately adjust the distance between the front wheel limit assembly and the rear wheel limit assembly according to the front and rear wheels. The setting of the protective curtain can prevent foreign objects from entering during the test and increase the safety of the test.

[0021] Preferably, the front special-shaped protrusion on the front drum rotating mechanism and the rear special-shaped protrusion on the rear drum rotating mechanism are in periodic contact with the front wheel and the rear wheel of the motorcycle so that the motorcycle can vibrate up and down. The front wheel and the front special-shaped protrusion are arranged through the rectangular opening A on the test platform, and the rear special-shaped protrusion and the rear wheel are arranged through the rectangular opening B on the test platform.

[0022] The design of rectangular opening A and rectangular opening B allows the front and rear wheels to rotate freely without affecting the overall structure of the test platform, making it easy for operators to adjust and monitor the motorcycle during the test.

[0023] Preferably, four sets of sockets are symmetrically arranged on the front and rear sides of the top of the test platform, and rings are rotatably sleeved on the four sets of sockets, and the rings are bound to the motorcycle body by elastic straps. The elastic straps can ensure that the motorcycle body is fixed in the correct position during the test to prevent sliding or displacement. The elastic straps can also absorb part of the vibration and reduce the direct impact on the motorcycle body.

[0024] Compared with the prior art, the technical effects and advantages of the present invention are:

[0025] This cross-motorcycle vibration durability test bench achieves precise control of the front and rear wheels of the motorcycle through the stable fixation of the front wheel limit assembly and the rear wheel limit assembly, as well as the driving of the front drum rotation mechanism and the rear drum rotation mechanism. The front wheel limit assembly clamps and fixes the front fork of the motorcycle through two limit plates, and the rolling wheel limits the front wheel to ensure that the front wheel maintains the correct position during the test. The rear wheel limit assembly limits the rear wheel through the I-shaped roller and the limit roller to prevent the rear wheel from shifting during the test. The translation mechanism drives the front wheel limit assembly and the front drum rotation mechanism to translate synchronously along the test platform to adjust the distance between the front and rear wheels to meet the test requirements of different types of motorcycles. The front drum rotation mechanism and the rear drum rotation mechanism provide rotational power for the motorcycle wheels through the drive motor and the transmission belt system to simulate the vibration conditions in actual driving.

[0026] The design of this cross-motorcycle type vibration durability test bench enables the motorcycle to be stably fixed on the test bench during the test, avoiding test errors caused by wheel movement, thereby improving the accuracy and reliability of the test. By simulating the vibration conditions during actual driving, the durability and reliability of various motorcycle components under long-term use can be more accurately evaluated.

[0027] The cross-motorcycle vibration durability test bench can adjust the distance between the front wheel limit assembly and the rear wheel limit assembly through the translation mechanism to meet the testing needs of motorcycles of different sizes and types. This flexible adjustment capability greatly broadens the scope of application of the test bench, allowing one test bench to meet the testing requirements of multiple models and improve the utilization rate of the test equipment.

[0028] The cross-motorcycle vibration durability test bench, through the design of the seat and the ring, and the binding of the elastic strap, can quickly install and remove the motorcycle during the test, improving the test efficiency. At the same time, this design also ensures that the motorcycle will not be displaced or overturned due to vibration during the test, increasing the safety of the test. The elastic strap can also absorb part of the vibration energy, reduce the direct impact on the motorcycle and the test bench, and protect the equipment from damage.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] The following combination Figures 1 to 5 Provide further details of this application;

[0043] The embodiment of the present application discloses a vibration durability test bench of a motorcycle-crossing type, comprising a front wheel limit assembly 1, a rear wheel limit assembly 2, a translation mechanism 3, a front drum rotation mechanism 6 and a rear drum rotation mechanism 7; a test platform 4, a base 5 and a support rod 8 constitute a test frame for installing the front wheel limit assembly 1, the rear wheel limit assembly 2, the translation mechanism 3, the front drum rotation mechanism 6 and the rear drum rotation mechanism 7. The front drum rotation mechanism 6 cooperates with the rear drum rotation mechanism 7 to provide driving force for the rotation of the motorcycle wheel.

[0044] The front wheel limiting assembly 1 is used to clamp and fix the front fork of the motorcycle. The front wheel limiting assembly 1 includes two limiting plates 101 for positioning the two sides of the front fork of the motorcycle and a rolling wheel 102 for limiting the front wheel of the motorcycle.

[0045] The front wheel limiting assembly 1 also includes two vertical supports A104 connected by a connecting rod A103, a connecting rod B105 connecting the top ends of the two vertical supports A104, two connecting plates A106 rotatably connected to the two connecting rods B105, and a connecting rod C107 connecting the two connecting plates A106. The two limiting plates 101 are rotatably sleeved on the outer side surfaces of both ends of the connecting rod C107 and are located on the inner sides of the two connecting plates A106.

[0046] The front wheel limiting assembly 1 also includes two horizontal plates 109 which are locked and fixed to the outside of the two vertical supports A104 by bolts 108. A number of straight slots 110 are symmetrically and evenly distributed on the two horizontal plates 109. After the bolts 108 penetrate the straight slots 110, the horizontal plates 109 are locked and fixed to the vertical supports A104. The rolling wheels 102 are rotatably arranged on the inner sides of the ends of the two horizontal plates 109.

[0047] The motorcycle front fork is clamped and fixed by two limit plates 101 to ensure that the motorcycle front fork does not move laterally during the test, thereby ensuring the accuracy of the test. The design of the limit plate 101 and the rolling wheel 102 can limit the front wheel to prevent the front wheel from deviating from the predetermined track during the test.

[0048] The two vertical supports A104 connected by the connecting rod A103 provide the basic support structure of the front wheel limit assembly 1, ensuring the stability of the assembly. The structural design of the connecting rod B105, the connecting rod C107 and the connecting plate A106 increases the integrity and rigidity of the entire limit assembly.

[0049] The straight slot 110 on the horizontal plate 109 is designed to allow the position of the horizontal plate 109 to be adjusted by the bolt 108, thereby adjusting the position of the limiting plate 101 to adapt to motorcycle front forks of different sizes.

[0050] The rolling wheel 102 is disposed inside the end of the horizontal plate 109 and can rotate freely on the horizontal plate 109, which helps to maintain the correct position of the wheel during the test.

[0051] The design of the front wheel limit assembly 1 allows it to be adjusted under different test conditions to adapt to different types of motorcycles and test requirements. By fixing and limiting, the front wheel limit assembly 1 protects the safety of the motorcycle during the test and prevents accidents caused by wheel movement.

[0052] In general, the function of the front wheel limit assembly 1 is to ensure that during the vibration durability test, the front wheel of the motorcycle can be stably fixed on the test bench and not be affected by external vibrations, while being able to simulate the vibration conditions in actual driving in order to evaluate the durability and reliability of the motorcycle.

[0053] The rear wheel limiting assembly 2 is used to limit the rear wheel of a motorcycle; the rear wheel limiting assembly 2 includes two vertical supports B201 fixed on the top of the test platform 4, a connecting rod D202 connecting the two vertical supports B201, two connecting plates B204 respectively located on the outside of the two vertical supports B201 and locked on the outer side of the connecting rod D202 by a locking nut 203, a connecting rod E205 connecting the two connecting plates B204, an I-shaped roller 206 rotatably sleeved on the outer side of the connecting rod E205 and cooperating with the rear wheel of the motorcycle to limit the position, two fixed blocks A207 fixedly sleeved on the outer side of the connecting rod E205 and located on both sides of the I-shaped roller 206, and a limiting roller 208 rotatably arranged on the two fixed blocks A207 and cooperating with the two sides of the rear wheel of the motorcycle to limit the position.

[0054] The rear wheel limiting assembly 2 limits the rear wheel of the motorcycle through the I-shaped roller 206 and the limiting roller 208 to ensure that the rear wheel does not move unnecessarily during the test, thereby maintaining the stability of the test. Through the design of the fixing block A207 and the limiting roller 208, the assembly can prevent the rear wheel from detaching from the test bench when it is vibrated, protecting the wheel and the test bench from damage. The design of the locking nut 203 and the connecting rod D202 allows the position of the limiting assembly to be adjusted to accommodate motorcycle rear wheels of different sizes. The design of the I-shaped roller 206 and the limiting roller 208 simulates the lateral force on the rear wheel during actual driving, which helps to evaluate the durability of the rear wheel assembly.

[0055] The translation mechanism 3 is used to drive the front wheel limiting assembly 1 and the front drum rotating mechanism 6 to translate synchronously along the test platform 4 to adjust the distance between the front wheel limiting assembly 1 and the rear wheel limiting assembly 2 so as to perform vibration durability detection tests on different types of motorcycles.

[0056] The translation mechanism 3 includes a servo screw linear module 301 installed on the base 5, a translation support 303 fixed on the moving slide 302 of the servo screw linear module 301, and a moving platform A304 and a moving platform B305 fixed on the top of the translation support 303 and located on both sides of the front drum rotating mechanism 6. The moving platforms A304 and B305 are both located below the rectangular opening A401 on the test platform 4. A protective curtain A306 that cooperates with the guide sliding of the test platform 4 is connected to one side of the moving platform A304, and a protective curtain B307 that cooperates with the guide sliding of the test platform 4 is connected to one side of the moving platform A304.

[0057] The two vertical supports A104 on the front wheel limiting assembly 1 are fixedly mounted on the top of the mobile platform B305;

[0058] The base 5 and the test platform 4 are connected via a plurality of support rods 8 .

[0059] A guide rail 308 is provided on the top of the base 5 , and a sliding block 309 which cooperates with the guide rail 308 to guide the sliding is fixedly provided on the bottom of the translation support 303 .

[0060] The translation mechanism 3 can drive the front wheel limit assembly 1 and the front drum rotating mechanism 6 to translate along the test platform 4 to adjust the distance between the front wheel and the rear wheel to adapt to different types of motorcycles and ensure that the test conditions meet the actual usage of different models. The precise control of the servo screw linear module 301 makes the position adjustment of the front wheel limit assembly 1 accurate and reliable, ensuring the repeatability and accuracy of the test. By translating the front wheel limit assembly 1, the test conditions can be quickly changed, so that different types of motorcycles can be tested for acute vibration durability.

[0061] The design of the protective curtain A306 and the protective curtain B307 prevents foreign matter from entering the test area during the test, and also prevents the operator from accidentally contacting the moving parts. The design of the base 5, the support rod 8 and the guide rail 308 provides a stable structural support, ensuring the stability and safety of the translation mechanism 3 during the movement.

[0062] The front drum rotating mechanism 6 includes two front bearing seats 601 fixed on the top of the base 5, a front rotating wheel 602 rotatably arranged between the two front bearing seats 601, a plurality of front special-shaped protrusions 603 arranged on the surface of the front rotating wheel 602, a front driving motor 604 fixed on the top of the base 5, a small pulley A605 fixedly connected to the output shaft of the front driving motor 604, a large pulley A606 fixed on the front rotating wheel 602, and a front driving belt 607 that transmits and connects the small pulley A605 and the large pulley A606.

[0063] Through the front drive motor 604 and the transmission belt system, the front drum rotating mechanism 6 provides rotational power for the front wheel of the motorcycle, simulating the front wheel movement of the motorcycle in actual driving. The front special-shaped protrusion 603 on the front rotating wheel 602 periodically contacts the front wheel of the motorcycle, generating up and down vibrations, simulating the vibration of the motorcycle when driving on a rough road surface. The precise control of the front drum rotating mechanism 6 helps to adjust the vibration frequency and amplitude to adapt to different test requirements and simulate different road conditions. The front bearing seat 601 is fixed to the top of the base 5 to provide stable support for the front rotating wheel 602 to ensure the accuracy of the test.

[0064] The rear drum rotating mechanism 7 includes two rear bearing seats 701 fixed on the top of the translation support 303, a rear rotating wheel 702 rotatably arranged between the two rear bearing seats 701, a plurality of rear special-shaped protrusions 703 arranged on the surface of the rear rotating wheel 702, a rear driving motor 704 fixed on the top of the base 5, a small pulley B705 fixedly connected to the output shaft of the rear driving motor 704, a large pulley B706 fixed on the rear rotating wheel 702, and a rear driving belt 707 that transmits and connects the small pulley B705 and the large pulley B706.

[0065] Similar to the front drum rotating mechanism 6, the rear drum rotating mechanism 7 provides rotational power for the rear wheel of the motorcycle through the rear drive motor 704 and the transmission belt system. The rear shaped protrusion 703 on the rear wheel 702 makes periodic contact with the rear wheel of the motorcycle, generating up and down vibrations, simulating the vibration of the rear wheel of the motorcycle during actual driving. The rear drum rotating mechanism 7 works in coordination with the front drum rotating mechanism 6 to ensure that the front and rear wheels of the motorcycle are subjected to force synchronously, providing a more realistic test environment. The rear bearing seat 701 is fixed to the top of the translation support 303 to provide stable support for the rear wheel 702, ensuring that the test results will not be affected by vibration during the test.

[0066] The front special-shaped protrusion 603 on the front drum rotating mechanism 6 and the rear special-shaped protrusion 703 on the rear drum rotating mechanism 7 are in periodic contact with the front wheel and the rear wheel of the motorcycle so that the motorcycle can vibrate up and down. The front rotating wheel 602 and the front special-shaped protrusion 603 are arranged through the rectangular opening A401 on the test platform 4, and the rear special-shaped protrusion 703 and the rear rotating wheel 702 are arranged through the rectangular opening B402 on the test platform 4.

[0067] The periodic contact between the special-shaped bump and the wheel generates vibration, causing the motorcycle to vibrate up and down on the test platform 4, simulating the dynamic load in actual driving. By simulating vibration, the durability and reliability of the motorcycle under long-term vibration can be evaluated, and possible fatigue damage can be detected. This periodic contact design can be carried out continuously without stopping to replace parts, which improves the test efficiency.

[0068] The front rotating wheel 602 and the front special-shaped protrusion 603, the rear special-shaped protrusion 703 and the rear rotating wheel 702 pass through the rectangular opening A401 and the rectangular opening B402 on the test platform 4, so that the rotating wheels and the special-shaped protrusions can work on the test platform 4 without affecting the overall structure of the test platform 4, thereby ensuring the stability of the test platform 4 and the safety of the test process.

[0069] Four sets of sockets 9 are symmetrically arranged on the front and rear sides of the top of the test platform 4. Rings 10 are rotatably sleeved on the four sets of sockets 9, and the rings 10 are bound to the motorcycle body through elastic straps.

[0070] The collar 10 is bound to the motorcycle body by an elastic band, ensuring that the motorcycle remains in a fixed position during the test and preventing the motorcycle from being displaced when subjected to vibration, thereby ensuring the accuracy of the test results. The elastic band has a certain buffering effect, which can absorb part of the vibration energy, reduce the direct impact of vibration on the motorcycle body and the test bench, and protect the motorcycle and the test equipment from damage. By using the design of the sleeve 9 and the collar 10, different motorcycles can be quickly installed and disassembled, improving the reusability and operating efficiency of the test bench. The design of the sleeve 9 can prevent the motorcycle from tipping over during the test, thereby improving the safety of the test. The design of the collar 10 and the elastic band allows the operator to intuitively monitor the status of the motorcycle during the test, promptly detect any abnormal conditions and make adjustments.

[0071] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
