Abstract
Description
Technical Field
[0001] This invention relates to the field of shock absorber testing technology, and more specifically, to a device for testing the performance of motorcycle shock absorbers. Background Technology
[0002] The main function of motorcycle shock absorbers is to mitigate and dampen the impact and vibration from the ground during motorcycle riding, reduce the dynamic stress of various parts of the vehicle body, extend the service life of the vehicle, and ensure the safety and riding experience of the user.
[0003] Currently, the performance testing of motorcycle shock absorbers mainly relies on various testing devices. The core testing logic is to simulate the stress and motion state of the shock absorber in actual use, making it reciprocate, while measuring and recording its damping force at different displacements and speeds, and then plotting the performance curve to determine whether its performance meets the design standards and usage requirements.
[0004] Most existing testing devices use a single-direction reciprocating loading method, which can only apply axial tensile and compressive forces to the shock absorber. They cannot simulate the irregular obstruction effect of different road conditions (such as potholes, bumps, and sloping surfaces) on the ground wheel during motorcycle operation. This results in a large deviation between the testing scenario and the actual use scenario, and the test results cannot fully reflect the true working performance of the shock absorber under complex road conditions. Summary of the Invention
[0005] In view of the problems existing in the prior art, the purpose of this invention is to provide a motorcycle shock absorber performance indicator detection device.
[0006] To solve the above problems, the present invention adopts the following technical solution.

The fixing component is used to fix the shock absorber. The fixing component includes a movable frame. A positioning block is rotatably installed inside the movable frame. A slot is opened on the lower side of the positioning block. The slot is used to fix the end of the shock absorber. The upper end of the testing platform is provided with a sliding groove, and an impact component is installed inside the sliding groove. The impact component is used to drive the end of the shock absorber away from the positioning block to move. The impact component includes a sliding frame slidably installed inside the sliding groove. An impact plate is rotatably installed on one side of the upper end of the sliding frame. A moving groove is provided on the upper side of the sliding frame. An adjustment component is installed inside the moving groove. The adjustment component is used to adjust the angle of the impact plate. An electro-hydraulic servo actuator is installed at one end of the sliding frame, which is used to drive the sliding frame to move back and forth.
[0008] Furthermore, a plurality of tension springs are fixedly installed at the end of the impact plate away from the movable frame, and the end of the tension spring away from the movable frame is fixedly connected to the upper end of the sliding frame.
[0009] Furthermore, the adjustment assembly includes a first threaded rod rotatably mounted inside the moving groove, an extrusion block slidably mounted inside the moving groove, the first threaded rod being threadedly connected to the extrusion block, the upper end of the extrusion block extruding against the outer wall of the impact plate, and the adjustment assembly also includes a stepper motor, the stepper motor being mounted inside the sliding frame, and the output end of the stepper motor being coaxially connected to the first threaded rod.
[0010] Furthermore, the impact plate has multiple movable slots, and a movable plate is slidably installed inside the movable slot. A pressure sensor is also installed inside the movable slot. When the movable plate moves, it squeezes the pressure sensor. Multiple connecting ropes are fixedly installed at one end of the movable plate inside the movable slot, and the end of the connecting rope away from the movable plate is fixedly connected to the inner wall of the movable slot.
[0011] Furthermore, two test wheels are placed on the upper side of the testing platform. The two test wheels are coaxially connected by a pin. The pin passes through the axle of one test wheel, the shock absorber, and the axle of the other test wheel in sequence. The impact plate is used to impact the outer wall of the test wheel.
[0012] Furthermore, a second threaded rod is rotatably mounted on one side of the movable frame, and a drive motor is mounted on the upper end of the second threaded rod. The drive motor is used to drive the second threaded rod to rotate. The upper side of the second threaded rod is rotatably connected to the movable frame, and the lower side of the second threaded rod is embedded inside the testing table and threadedly connected to the testing table.
[0013] Furthermore, a guide rod is fixedly installed at the lower end of the side of the movable frame away from the second threaded rod. The end of the guide rod away from the movable frame is embedded inside the testing table and slidably connected to the testing table. The guide rod is used to limit the movement direction of the movable frame.
[0014] Furthermore, the movable frame has multiple first insertion holes, and the positioning block has a second insertion hole at the position corresponding to the slot. A fixing pin is inserted into the first insertion hole, and the end of the fixing pin passes through the second insertion hole.
[0015] Furthermore, a constant temperature chamber is installed outside the testing platform to keep the shock absorber under test warm. A controller is installed outside the constant temperature chamber to control the operation of the electro-hydraulic servo actuator, drive motor, and stepper motor. A data processing module is also installed outside the constant temperature chamber. The pressure sensor transmits data to the data processing module, which records the pressure sensor values and sends electrical signals to the controller.
[0016] Furthermore, two stroke sensors are fixedly installed at the lower end of the positioning block. The stroke sensors transmit data to the data processing module, which records the values of the stroke sensors.
[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The present invention simulates non-axial, irregular lateral and tangential impact forces such as potholes, bumps, and sloping road surfaces by setting an adjustable angle impact plate and test wheel structure. It restores the effect of irregular ground obstruction on the shock absorber when the motorcycle is actually driving. It solves the problem that the existing device only loads axially and has a large deviation from the actual working conditions. The test results are more realistic and comprehensively reflect the shock absorption performance under complex road conditions, making the test results more accurate and more representative.
[0018] (2) The present invention adjusts the height of the fixed end of the shock absorber by setting the second threaded rod, drive motor, and lifting structure of the moving frame, thereby changing the initial pre-compression and pre-elongation of the shock absorber, simulating the initial force state of the shock absorber when riders of different weights ride, and meeting the power indication detection requirements under multiple load conditions.
[0019] (3) The present invention achieves automatic adjustment of the tilt angle of the impact plate by setting a stepper motor, a first threaded rod, a squeezing block and a tension spring, changing the contact position and force angle between the impact plate and the test wheel, and can switch between multiple road surface simulation conditions with one click. With the closed loop of pressure sensor data, it can realize automatic multi-angle continuous detection of a single batch without the need for repeated adjustments by staff.
[0020] (4) The present invention uses a stroke sensor to compare the displacement difference between the two sides in real time, and accurately identifies deformation defects such as skewness, twisting, and misalignment of the shock absorber oil reservoir and piston rod. Traditional devices can only measure the overall stroke and cannot judge lateral deformation. This device has the dual functions of power indication detection and structural defect detection.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0024] Please see Figures 1 to 8 A motorcycle shock absorber performance indicator testing device includes a testing platform 1, a fixing component 2 installed on the upper side of the testing platform 1, the fixing component 2 is used to fix the shock absorber, the fixing component 2 includes a movable frame 201, a positioning block 202 is rotatably installed inside the movable frame 201, and a slot 203 is opened on the lower side of the positioning block 202, the slot 203 is used to fix the end of the shock absorber. The upper end of the testing table 1 is provided with a slide groove 101. An impact component 3 is installed inside the slide groove 101. The impact component 3 is used to drive the end of the shock absorber away from the positioning block 202 to move. The impact component 3 includes a sliding frame 301 slidably installed inside the slide groove 101. An impact plate 302 is rotatably installed on one side of the upper end of the sliding frame 301. A moving groove 303 is provided on the upper side of the sliding frame 301. An adjustment component 4 is installed inside the moving groove 303. The adjustment component 4 is used to adjust the angle of the impact plate 302. An electro-hydraulic servo actuator 304 is installed at one end of the sliding frame 301. The electro-hydraulic servo actuator 304 is used to drive the sliding frame 301 to reciprocate. Two test wheels 102 are placed on the upper side of the test table 1. The two test wheels 102 are coaxially connected by a pin 103. The pin 103 passes through the shaft of one test wheel 102, the shock absorber, and the shaft of the other test wheel 102 in sequence. The impact plate 302 is used to impact the outer wall of the test wheel 102.
[0025] By adopting the above technical solution, before use, the fixed end of the shock absorber is inserted into the slot 203, and the movable end of the shock absorber is aligned with the axis of the two test wheels 102. The pin 103 is then inserted into the axis of the test wheel 102, and simultaneously, the pin 103 is inserted into the mounting hole of the movable end of the shock absorber. Then, the electro-hydraulic servo actuator 304 drives the sliding frame 301 to move back and forth continuously. When the sliding frame 301 moves, it can drive the impact plate 302 on its upper side. After the impact plate 302 moves, it can impact the outer wall of the test wheel 102. When an impact occurs, the test wheel 102 can drive the movable end of the shock absorber to move through the pin 103. After the movable end of the shock absorber moves, it can retract. When the impact plate 302 no longer contacts the outer wall of the test wheel 102, the shock absorber can extend and return to the state before the impact. The adjustment component 4 can adjust the orientation of the impact plate 302. After the orientation of the impact plate 302 changes, the impact plate 302 can impact different positions of the test wheel 102, thereby simulating the impact of the ground blocking the test wheel 102 on the shock absorber under different road conditions.
[0026] Multiple tension springs 305 are fixedly installed at the end of the impact plate 302 away from the moving frame 201. The ends of the tension springs 305 away from the moving frame 201 are fixedly connected to the upper end of the sliding frame 301. The adjustment assembly 4 includes a first threaded rod 401 rotatably installed inside the moving groove 303. A pressing block 306 is slidably installed inside the moving groove 303. The first threaded rod 401 is threadedly connected to the pressing block 306. The upper end of the pressing block 306 presses against the outer wall of the impact plate 302. The adjustment assembly 4 also includes a stepper motor 402, which is installed inside the sliding frame 301. The output end of the stepper motor 402 is coaxially connected to the first threaded rod 401.
[0027] By adopting the above technical solution, when the stepper motor 402 is working, it can drive the first threaded rod 401 to rotate. After the first threaded rod 401 rotates, it can drive the sliding frame 301 to move. After the first threaded rod 401 moves, it can drive the extrusion block 306 to move. After the extrusion block 306 moves, under the action of the tension spring 305, the impact plate 302 can always be in contact with the outer wall of the extrusion block 306. At this time, the extrusion block 306 can always be in contact with the impact plate 302 and support it. By adjusting the position of the extrusion block 306, the tilt angle of the impact plate 302 can be controlled. After the angle of the impact plate 302 changes, the contact position between the impact plate 302 and the test wheel 102 will also change during the movement.
[0028] Multiple movable slots 307 are provided on the impact plate 302. A movable plate 308 is slidably installed inside the movable slot 307. A pressure sensor 309 is also installed inside the movable slot 307. After the movable plate 308 moves, it squeezes the pressure sensor 309. Multiple connecting ropes 310 are fixedly installed at one end of the movable plate 308 inside the movable slot 307. The end of the connecting rope 310 away from the movable plate 308 is fixedly connected to the inner wall of the movable slot 307.
[0029] By adopting the above technical solution, after the test wheel 102 is impacted by the impact plate 302, the test wheel 102 will come into contact with the movable plate 308, thereby squeezing the movable plate 308. At this time, the movable plate 308 can squeeze the pressure sensor 309 inside the movable groove 307. The connecting rope 310 can keep the movable plate 308 inside the movable groove 307.
[0030] A second threaded rod 204 is rotatably mounted on one side of the movable frame 201. A drive motor 205 is mounted on the upper end of the second threaded rod 204. The drive motor 205 is used to drive the second threaded rod 204 to rotate. The upper side of the second threaded rod 204 is rotatably connected to the movable frame 201, and the lower side of the second threaded rod 204 is embedded in the test table 1 and threadedly connected to the test table 1. A guide rod 206 is fixedly mounted on the lower end of the side of the movable frame 201 away from the second threaded rod 204. The end of the guide rod 206 away from the movable frame 201 is embedded in the test table 1 and slidably connected to the test table 1. The guide rod 206 is used to limit the movement direction of the movable frame 201. Multiple first insertion holes 207 are provided through the mobile frame 201. Second insertion holes 208 are provided at the positions corresponding to the positioning block 202 and the slot 203. A fixing pin 209 is inserted into the first insertion hole 207, and the end of the fixing pin 209 passes through the second insertion hole 208.
[0031] By adopting the above technical solution, when the drive motor 205 is working, it can drive the second threaded rod 204 to rotate. After the second threaded rod 204 rotates, it can drive the movable frame 201 connected to it to move. At this time, under the restriction of the guide rod 206, the movable frame 201 can only move along the direction of the guide rod 206. When the movable frame 201 moves, it can drive the positioning block 202 on its lower side to move, thereby changing the position of the fixed end of the shock absorber. In this way, the pressure of the movable end of the shock absorber on the pin 103 can be changed, thereby simulating the shock absorption when people of different weights sit on a motorcycle. The initial extension range of the device, wherein, when it is necessary to fix the positioning block 202, the second socket 208 on the positioning block 202 is aligned with the first socket 207, and then the fixing pin 209 is inserted into the first socket 207 and the second socket 208, so that the positioning block 202 is fixed relative to the moving frame 201. When it is necessary to adjust the orientation of the positioning block 202, the fixing pin 209 is pulled out, the second socket 208 is aligned with the other first socket 207, and then the fixing pin 209 is inserted into the first socket 207 and the second socket 208 again to fix the positioning block 202.
[0032] The testing platform 1 is equipped with a constant temperature chamber 104, which is used to keep the shock absorber under test warm. A controller 105 is installed outside the constant temperature chamber 104. The controller 105 is used to control the operation of the electro-hydraulic servo actuator 304, drive motor 205, and stepper motor 402. A data processing module 106 is also installed outside the constant temperature chamber 104. The pressure sensor 309 transmits data to the data processing module 106. The data processing module 106 can be a microcontroller. The data processing module 106 is used to record the value of the pressure sensor 309 and to send electrical signals to the controller 105.
[0033] By adopting the above technical solution, the constant temperature chamber 104 can effectively play the role of heat preservation, enabling the shock absorber to be tested at different ambient temperatures, thereby simulating different outdoor environments and judging the performance of the shock absorber under different environments. The data from the pressure sensor 309 can be transmitted to the data processing module 106. The data processing module 106 can record the data transmitted by the pressure sensor 309 each time. When the data transmitted by the pressure sensor 309 remains stable, the data processing module 106 sends a signal to the controller 105. At this time, the controller 105 can control the stepper motor 402 to work once, so that the first threaded rod 401 rotates a certain angle.
[0034] Two stroke sensors 210 are fixedly installed at the lower end of the positioning block 202. The stroke sensors 210 transmit data to the data processing module 106, which records the values of the stroke sensors 210.
[0035] By adopting the above technical solution, the ends of the two stroke sensors 210 away from the positioning block 202 are installed on the movable end of the shock absorber. When the shock absorber extends or retracts, the stroke sensors 210 can detect the extension or retraction range of the shock absorber. One stroke sensor 210 is located on the side closer to the impact plate 302, and the other stroke sensor 210 is located on the side away from the impact plate 302. The data processing module 106 can record the data of the two stroke sensors 210 separately and compare the data transmitted by the stroke sensors 210 each time to determine whether there is a difference between the values on the two stroke sensors 210. When the value detected by one stroke sensor 210 is different from the data detected by the other stroke sensor 210, it indicates that the oil reservoir of the shock absorber has deformed relative to the piston rod.
[0036] Instructions for use: First, insert the fixed end of the shock absorber into the slot 203 on the lower side of the positioning block 202. Then, align the movable end of the shock absorber with the axles of the two test wheels 102. Insert the pin 103 sequentially through the axle of one test wheel 102, the mounting hole of the movable end of the shock absorber, and the axle of the other test wheel 102 to complete the initial fixing of the shock absorber. Subsequently, according to the testing requirements, start the drive motor 205 to drive the second threaded rod 204 to rotate. Under the limiting action of the guide rod 206, the moving frame 201 drives the positioning block 202 to move up and down to adjust the position of the fixed end of the shock absorber. The initial extension of the shock absorber is simulated when people of different weights ride on it. After adjustment, the second insertion hole 208 on the positioning block 202 is aligned with the corresponding first insertion hole 207 on the moving frame 201, and the fixing pin 209 is inserted to fix the positioning block 202. If it is necessary to adjust the orientation of the positioning block 202, the fixing pin 209 can be pulled out, the second insertion hole 208 can be aligned with the other first insertion holes 207, and then the fixing pin 209 can be reinserted. Then, the temperature of the constant temperature chamber 104 is set by the controller 105 to keep the shock absorber warm to simulate different outdoor environments, and then the stepper motor 402 is started to drive the first thread. The rod 401 rotates, causing the compression block 306 to move within the moving groove 303. With the assistance of the tension spring 305, the tilt angle of the impact plate 302 is adjusted, thus determining the impact position of the impact plate 302 on the test wheel 102. Then, the controller 105 activates the electro-hydraulic servo actuator 304, causing the sliding frame 301 to reciprocate within the sliding groove 101. As the sliding frame 301 moves, it causes the impact plate 302 to impact the outer wall of the test wheel 102. The test wheel 102, through the pin 103, causes the movable end of the shock absorber to extend and retract. During this process, the movable plate 308 is compressed by the test wheel 102. The pressure sensor 309 and stroke sensor 210 in the rear compression groove 307 synchronously detect the extension and contraction of the shock absorber. The pressure sensor 309 and stroke sensor 210 transmit the detected data to the data processing module 106. The data processing module 106 records and analyzes the data. When the data from the pressure sensor 309 is stable, the data processing module 106 sends a signal to the controller 105. The controller 105 controls the stepper motor 402 to work to adjust the angle of the impact plate 302, simulating the obstruction effect of different road conditions on the test wheel 102, and completing the performance test of the shock absorber.
