Description

Technical Field

[0001] This invention mainly relates to the field of automotive clutch cover assembly testing technology, and specifically to an automotive clutch cover assembly testing device. Background Technology

[0002] The automotive clutch cover assembly testing apparatus is used for performance testing and verification of automotive clutch cover assemblies. Tests include: vibration testing, which simulates the vibration experienced by the clutch cover assembly under actual driving conditions; friction testing, which evaluates the performance of the clutch cover assembly during friction processes, typically simulating the friction force between the friction plates and the clutch disc to determine the contact performance, wear, and coefficient of friction between the friction plates and the clutch cover; and durability testing, which simulates the durability of the clutch cover assembly during long-term use. These tests provide an assessment of the clutch cover assembly's structural strength, vibration resistance, friction performance, and durability.

[0003] For example, Chinese Patent Publication No. CN108132146B provides a testing device for the fatigue durability and thermal fade of an automotive clutch. This application can satisfy the performance tests for clutch cover assembly separation fatigue durability, driven plate assembly axial compression fatigue life, cover assembly diaphragm and transmission plate thermal fade, and driven plate wave plate thermal fade. However, the existing technology does not have a device that can simultaneously perform durability testing, friction testing, and vibration testing on an automotive clutch cover assembly. Testing needs to be conducted on multiple testing devices, which may differ in hardware configuration, control methods, and accuracy. This can lead to differences in test results, thus affecting the comparability and consistency of the results. Summary of the Invention

The second testing device includes a base, on which two second support frames are symmetrically arranged, and a mounting ring is rotatably mounted between the two second support frames. The mounting ring is used to fix the clutch cover assembly. A connecting tooth groove is provided at the center of the clutch cover assembly. A fixing cylinder is provided on the base, and a clamping block is provided on the output end of the fixing cylinder for fixing the position of the mounting ring. The lower end of the base is mounted on the mounting platform via a sliding mechanism. The first testing device includes a first support frame, on which a crank-slider mechanism is mounted. A connecting tooth is provided on the output end of the crank-slider mechanism for connecting with the connecting tooth groove. A friction roller is rotatably arranged on the third testing device, and the friction roller is used to rub the clutch cover assembly.

[0006] Preferably, two "L"-shaped mounting brackets are symmetrically arranged at both ends of the mounting ring. The mounting brackets are rotatably mounted on the second support frame via a rotating shaft, and one of the rotating shafts extends out and is connected to the drive mechanism.

[0007] Preferably, the sliding mechanism includes a slider fixed to the lower end of the base and a guide rail fixed to the mounting platform, wherein the slider is slidably mounted on the guide rail.

[0008] Preferably, the drive mechanism includes a mounting plate fixed on the base, a second motor fixedly mounted on the mounting plate, the motor shaft of the second motor extending out of the mounting plate and fixedly connected to the driving synchronous pulley, the driving synchronous pulley being connected to the driven synchronous pulley via a synchronous belt, and the driven synchronous pulley being fixed on the rotating shaft.

[0009] Preferably, the crank-slider mechanism includes a first motor and a mounting block fixed on a first support frame. The motor shaft of the first motor is fixedly connected to a turntable. A connecting rod is rotatably mounted on the turntable. The other end of the connecting rod is rotatably connected to a moving block. A guide groove is provided on the mounting block. The moving block is slidably mounted in the guide groove, and its right end is fixedly connected to a connecting tooth.

[0010] Preferably, a threaded shaft is provided at the right end of the connecting tooth, and a limit plate and a locking nut are installed on the threaded shaft by thread rotation. The limit plate and the locking nut are used to fix the clutch cover assembly.

[0011] Preferably, the third testing device includes a third support frame, on which two friction rollers are rotatably mounted, and the two friction rollers are connected to a third motor for transmission.

[0012] Preferably, the third testing device further includes limiting blocks symmetrically arranged at the front and rear ends of the third support frame. Bearing seats are provided at the left and right ends of the third support frame, and are slidably installed between the two limiting blocks. A screw is rotatably installed between the bearing seats through a bearing. A threaded sleeve is installed on the screw, one end of which extends out of the bearing seat and is fixedly connected to the handle. The third support frame is installed on the outside of the threaded sleeve.

[0013] 3. Beneficial effects Compared with the prior art, the technical solution provided by this invention has the following advantages: This invention integrates durability testing with a first testing device, vibration testing with a second testing device, and friction testing with a third testing device into a single testing device. This allows for the comprehensive evaluation of the automotive clutch cover assembly, eliminating the need for separate equipment and procedures for each test. This invention ensures the consistency and comparability of test data. By using the same device and testing procedures, it reduces differences and errors between devices, improving the reliability and comparability of the data.

[0014] The present invention uses the mounting ring, fixing cylinder, and clamping block of the second testing device as a fixture for the clutch cover assembly, and connects the clutch cover assembly through the connecting teeth of the first testing device. The crank-slider mechanism of the first testing device simulates actual working conditions, and the sliding mechanism drives the clutch cover assembly to move back and forth, allowing the clutch cover assembly to undergo continuous movement to simulate long-term use. According to the set test conditions, the test is continuously carried out, the test data is recorded, and the wear of the clutch cover assembly is observed. During the movement of the clutch cover assembly, the friction roller of the third testing device performs a friction test on the clutch cover assembly. The present invention can complete multiple test steps with the same device, which can save time and resources and improve test efficiency.

[0015] After the friction test and durability test, the present invention separates the connecting teeth and connecting tooth groove, and at the same time fixes the cylinder to drive the clamping block away from the mounting ring. Then the drive mechanism is started, and the mounting ring is rotated through the mounting frame and the rotating shaft. Since the mounting frame is "L" shaped, the clutch cover assembly is flipped to realize the vibration test and record the vibration characteristics of the clutch cover assembly at different rotation speeds. The present invention can provide a more comprehensive understanding of the performance of the clutch cover assembly. Attached Figure Description

[0023] See attached document Figures 1-6 The automotive clutch cover assembly testing device includes a mounting platform 1. From left to right, a first testing device 2, a second testing device 3, and a third testing device 4 are sequentially arranged on the mounting platform 1. The second testing device 3 includes a base 31, on which two second support frames 32 are symmetrically arranged. A mounting ring 34 is rotatably mounted between the two second support frames 32. The mounting ring 34 is used to fix the clutch cover assembly 5. A connecting tooth groove 51 is provided at the center of the clutch cover assembly 5. A fixing cylinder 36 is provided on the base 31. A clamping block 37 is provided on the output end of the fixing cylinder 36 to fix the position of the mounting ring 34. The lower end of the base 31 is mounted on the mounting platform 1 via a sliding mechanism 39. The first testing device 2 includes a first support frame 21, on which a crank-slider mechanism is mounted. A connecting tooth 28 is provided on the output end of the crank-slider mechanism for connecting with the connecting tooth groove 51. A friction roller 47 is rotatably arranged on the third testing device 4, and the friction roller 47 is used to rub the clutch cover assembly 5.

[0024] The mounting ring 34 has two symmetrically arranged "L"-shaped mounting brackets 33 at both ends. The mounting brackets 33 are rotatably mounted on the second support frame 32 via a rotating shaft 35. One rotating shaft 35 extends out and is connected to the drive mechanism 38.

[0025] The sliding mechanism 39 includes a slider 392 fixed to the lower end of the base 31 and a guide rail 391 fixed to the mounting platform 1. The slider 392 is slidably mounted on the guide rail 391.

[0026] The drive mechanism 38 includes a mounting plate 381 fixed on the base 31. A second motor 382 is fixedly mounted on the mounting plate 381. The motor shaft of the second motor 382 extends out of the mounting plate 381 and is fixedly connected to the active synchronous pulley 383. The active synchronous pulley 383 is connected to the driven synchronous pulley 385 through the synchronous belt 384. The driven synchronous pulley 385 is fixed on the rotating shaft 35.

[0027] The crank-slider mechanism includes a first motor 22 and a mounting block 26 fixed on a first support frame 21. The motor shaft of the first motor 22 is fixedly connected to a turntable 23. A connecting rod 24 is rotatably mounted on the turntable 23. The other end of the connecting rod 24 is rotatably connected to a moving block 25. A guide groove 27 is provided on the mounting block 26. The moving block 25 is slidably mounted in the guide groove 27, and its right end is fixedly connected to a connecting tooth 28.

[0028] A threaded shaft is provided at the right end of the connecting tooth 28. A limit plate 29 and a locking nut are mounted on the threaded shaft by rotating the thread. The limit plate 29 and the locking nut are used to fix the clutch cover assembly 5.

[0029] The third testing device 4 includes a third support frame 42, on which two friction rollers 47 are rotatably mounted, and the two friction rollers 47 are connected to a third motor 48 for transmission.

[0030] The third testing device 4 also includes limiting blocks 41 symmetrically arranged at the front and rear ends of the third support frame 42. Bearing seats 43 are provided at the left and right ends of the third support frame 42, and are slidably installed between the two limiting blocks 41. A screw 44 is rotatably installed between the bearing seats 43 through the bearing. A threaded sleeve 45 is installed on the screw 44, one end of which extends out of the bearing seat 43 and is fixedly connected to the handle 46. The third support frame 42 is installed on the outside of the threaded sleeve 45.

[0031] Work process: The fixed cylinder 36 of the second test device 3 extends, driving the clamping block 37 to lock the position of the mounting ring 34, keeping the position of the mounting ring 34 fixed. The mounting ring 34 serves as a clamp for the clutch cover assembly 5. The clutch cover assembly 5 is then connected to the first test device 2 via the connecting teeth 28. The clutch cover assembly 5 can also be further fixed via the threaded shaft, the limiting plate 29, and the locking nut, ensuring that the two can move firmly during the test. The first motor 22 of the crank-slider mechanism drives the turntable 23 to rotate, which in turn drives the moving block 25 to slide left and right in the guide groove 27 via the connecting rod 24, simulating actual working conditions. The sliding mechanism 39 drives the clutch cover assembly 5 to move back and forth, thus causing the clutch cover assembly 5 to move continuously, simulating long-term use. According to the set test conditions, the test is continuously conducted, and the test data and wear of the clutch cover assembly 5 are recorded. During the movement of the clutch cover assembly 5, the third motor 48 of the third test device 4 drives the friction roller 47 to rotate. During the reciprocating motion of the clutch cover assembly 5, when the clutch cover assembly 5 reaches the right top, the friction roller 47 performs a friction test on the clutch cover assembly 5. By turning the handle 46, the screw 44 is driven to rotate, causing the threaded sleeve 45 to move on the screw 44, thereby causing the third support frame 42 to move back and forth between the limit blocks 41, thus adjusting the position of the friction roller 47 from the clutch cover assembly 5, adapting to different test environments and testing different models of clutch cover assemblies 5.

[0032] After the friction test and durability test are completed, the connecting tooth 28 and the connecting tooth groove 51 are separated. At the same time, the fixed cylinder 36 drives the clamping block 37 to leave the mounting ring 34. Then, the second motor 382 of the drive mechanism 38 is started. The motor shaft of the second motor 382 rotates, thereby driving the rotating shaft 35 to rotate through the active synchronous pulley 383, the synchronous belt 384 and the driven synchronous pulley 385. The rotating shaft 35 drives the mounting ring 34 to rotate through the mounting bracket 33. Since the mounting bracket 33 is "L" shaped, the clutch cover assembly 5 is flipped to realize the vibration test and record the vibration characteristics of the clutch cover assembly 5 at different rotation speeds. This invention can provide a more comprehensive understanding of the performance of the clutch cover assembly 5.

[0033] Durability testing is performed using the first testing device 2, vibration testing using the second testing device 3, and friction testing using the third testing device 4. By integrating vibration testing, friction testing, and durability testing into a single testing device, the overall performance of the automotive clutch cover assembly can be evaluated. This eliminates the need to prepare separate equipment and testing procedures for each test. The present invention ensures the consistency and comparability of test data. By using the same device and testing procedures, the differences and errors between devices can be reduced, improving the reliability and comparability of the data.

[0034] The above-described embodiments are merely illustrative of certain implementations of the present invention, and are described in a relatively specific and detailed manner. However, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
