Description

Technical Field

[0001] This invention relates to the field of shock absorber testing technology, and in particular to a shock absorber damping strength testing device. Background Technology

[0002] Shock absorbers, as the core damping components of a vehicle's suspension system, directly determine the vehicle's ride comfort, handling stability, driving safety, and even the service life of key components. The "damping strength" of a shock absorber is a comprehensive indicator, encompassing not only the damping force characteristics provided during different compression and recovery strokes, but also the load-bearing limit, fatigue life, and dynamic response reliability of its mechanical structure under complex alternating loads. Therefore, conducting precise, efficient, and realistic strength testing of shock absorbers throughout their entire lifecycle, from R&D and design to manufacturing and quality acceptance, is the cornerstone for ensuring product quality, optimizing product design, and meeting increasingly stringent vehicle performance requirements.

[0003] However, the traditional shock absorber strength testing equipment and methods widely used in the industry have long had significant limitations, making it difficult to meet the demands of modern manufacturing for flexible, intelligent, and high-fidelity testing. Their drawbacks are mainly concentrated in the following two core aspects:

[0004] Firstly, the specimen clamping and fixing process suffers from poor versatility, low efficiency, and a high risk of damage. Traditional equipment relies heavily on rigid, dedicated fixtures for each type of shock absorber, especially those with different end connection structures. This necessitates maintaining a large fixture inventory, resulting in high management costs. Changing fixtures when producing different models is also cumbersome, severely hindering testing efficiency and failing to adapt to the trend of flexible production with "multiple varieties and small batches." In pursuit of some versatility, some equipment uses simple clamping methods such as V-blocks and universal pressure plates, which often suffer from uneven clamping force, small contact area, and unreliable locking. Under high loads, slippage or loosening can easily occur, affecting data accuracy. Furthermore, rigid contact can leave indentations on the shock absorber's paint or soft components, causing product damage. For shock absorbers with irregular geometric shapes or fragile components at the ends, existing clamping methods are completely ineffective.

[0005] Secondly, in the testing mechanism and operating condition simulation stages, the testing dimensions are singular, resulting in a severe disconnect from real-world operating conditions. The vast majority of traditional testing equipment employs a linear loading mode of "fixed mounting base + unidirectional actuating cylinder." The shock absorber is fixed vertically or horizontally between two rigid supports, and the actuating cylinder performs linear reciprocating loading along its theoretical axis. This mode has a fundamental flaw: it ignores the decisive influence of the spatial installation angle. In actual vehicles, due to the vast differences in chassis layout, shock absorbers are by no means always vertically mounted, but rather exhibit various tilt angles. A shock absorber that performs excellently in vertical testing will experience significant changes in the damping force generated by its internal valve system, the lateral forces on the piston rod and oil seal, and the combined stress state of the spring assembly at a certain tilt angle, potentially leading to drastically different fatigue failure modes. A single axial test cannot reveal these potential risk points. Furthermore, traditional equipment cannot accurately simulate the full-stroke, multi-posture dynamic loads experienced by shock absorbers under complex road conditions. The test data can only reflect its performance under "laboratory conditions" and cannot provide sufficient verification of the reliability of vehicles under extreme handling or harsh road conditions.

[0006] In recent years, with the rapid iteration of the automotive industry, especially the pursuit of lightweight and integrated chassis design in new energy vehicles, and the continuous improvement of consumers' requirements for vehicle driving quality, shock absorbers are developing towards more complex structures, more refined performance, and more diverse models. The market has presented unprecedented challenges to testing technology: on the one hand, it requires testing equipment to have broad adaptability and be versatile, reducing investment and operating costs; on the other hand, it requires test results to accurately and comprehensively reflect the product's extreme performance in actual applications.

[0007] The present invention aims to solve the technical problems existing in the prior art. To this end, a shock absorber damping strength testing device is proposed. Summary of the Invention

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] 1. The clamping operation is efficient and convenient, and it has a wide range of applications.

[0025] Quick clamping and connection: The equipment adopts a split design, with a "quick clamping module" with an adaptive arc-shaped clamping unit pre-fixed to both ends of the shock absorber, and then quickly locked to the main unit using a "quick snap-fit ​​module". This process simplifies the operation steps and significantly improves clamping and disassembly efficiency.

[0026] Contour-adaptive clamping: The clamping module employs multiple independently radially adjustable clamping units equipped with "arc-shaped rubber airbags." Under the action of the return spring, each unit can adapt to the irregular shape of the shock absorber end profile, achieving uniform and flexible wrap-around clamping, effectively protecting the workpiece surface and significantly expanding the range of shock absorber models that the equipment can detect.

[0027] 2. Comprehensive and in-depth testing capabilities, simulating realistic working conditions.

[0028] Multi-degree-of-freedom spatial attitude simulation: The core "displacement strength detection module" integrates steering drive and multiple sets of steering knuckle structures, enabling the clamped shock absorber to be flexibly adjusted to various installation angles in three-dimensional space, accurately simulating its actual working attitude on the vehicle.

[0029] Synchronous pressure application and full stroke testing: By controlling the operation of the two "synchronous drive telescopic columns" through a unified "hydraulic drive unit," the shock absorber can be smoothly and synchronously driven to compress and rebound, accurately covering its entire working stroke, and test loads can be applied at any set angle. This composite testing mode of angle and stroke can comprehensively evaluate the strength and durability of the shock absorber under different real-world working conditions.

[0030] 3. The overall structure is stable and flexible, facilitating integration and debugging.

[0031] Adjustable rigid frame: The support arm of the detection module can rotate around the axis to adjust the initial position to accommodate shock absorbers of different lengths, and can be quickly fixed by a threaded locking mechanism to ensure the rigidity of the core support structure during the test.

[0032] Modular functional layout: The equipment clearly modularizes clamping, connection, adjustment, driving, and testing functions, resulting in a compact structure and clear logic. This not only facilitates equipment installation, maintenance, and functional expansion, but also makes the operation process intuitive and lowers the barrier to entry for users.

Detailed Implementation

[0045] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0046] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0047] Example 1, please refer to Figure 1 , Figure 2 In this embodiment of the invention, a shock absorber damping strength testing device includes two combined clamping mechanisms arranged opposite each other. Each combined clamping mechanism includes a combined mounting plate 1, the edge of which is provided with a limiting rotation groove 18. A quick clamping module and a quick snap-fit ​​module are provided on one side of the combined mounting plate 1. The quick clamping module includes a clamping mounting plate 3 and further includes:

[0048] The combined strength testing mechanism includes several sets of displacement strength testing modules that are movably mounted on the combined installation panel 1.

[0049] The shock absorber is placed at both ends of the two combined clamping mechanisms. Specifically, the clamping mounting plate 3 is fixed to the end of the shock absorber through the quick clamping module, and then the clamping mounting plate 3 with the shock absorber clamped is installed on the combined mounting plate 1 through the quick snap-fit ​​module. Then, the displacement strength detection module is adjusted to adjust the spacing of the combined mounting plate 1, so that the shock absorber can be subjected to pressure testing within the shock absorption stroke range, thereby realizing the strength testing operation of the shock absorber.

[0050] Example 2, based on Example 1, please refer to... Figures 1 to 7 In this embodiment of the invention, the quick snap-fit ​​module includes a snap-fit ​​ball 20 disposed on one side of the clamping mounting plate 3. A snap-fit ​​groove 19 is disposed on one side of the combined mounting plate 1 in conjunction with the snap-fit ​​ball 20. A plurality of guide telescopic grooves 21 are disposed at equal angles on the edge of the snap-fit ​​groove 19. A guide telescopic post 22 is disposed in conjunction with each guide telescopic groove 21. A limit arc surface protrusion 41 is disposed at one end of the guide telescopic post 22 facing the snap-fit ​​ball 20. A telescopic spring post 23 is disposed between the other end of the guide telescopic post 22 and the guide telescopic groove 21.

[0051] The quick clamping module includes several limiting guide grooves 16 set at equal angles on the other side of the clamping mounting plate 3. Each limiting guide groove 16 is provided with a limiting guide post 28. Each limiting guide groove 16 is provided with a displacement screw 27. The displacement screw 27 passes through the limiting guide post 28, and the limiting guide post 28 is provided with a displacement screw hole 31 in conjunction with the displacement screw 27. One end of the displacement screw 27 is rotatably connected to the end of the limiting guide groove 16, and the other end of the displacement screw 27 is provided with a displacement driving component 24. The displacement driving component 24 is fixed on the clamping mounting plate 3.

[0052] One side of the limiting guide post 28 is provided with a synchronous installation post 4, and the synchronous installation post 4 extends out of the limiting guide groove 16. The limiting guide post 28 is provided with guide installation cylinders 26 at equal intervals. Guide installation posts 25 are provided in conjunction with the guide installation cylinders 26. The guide installation posts 25 are parallel to the limiting guide groove 16. One end of the guide installation post 25 is provided with an arc-shaped clamping plate 39. An arc-shaped rubber airbag 40 is provided on the arc-shaped clamping plate 39. The other end of the guide installation post 25 is provided with a reset installation plate 32. A reset spring 33 is provided between the reset installation plate 32 and the synchronous installation post 4.

[0053] Take a pair of mounting plates 3 and place them at both ends of the shock absorber. Drive the displacement screw 27 to rotate through the displacement drive component 24, so that it cooperates with the displacement screw hole 31 to realize the movement of the limit guide column 28. With the cooperation of the limit guide groove 16, the stable movement of the limit guide column 28 is guaranteed.

[0054] As the guide post 28 moves, the post 4 and the guide mounting cylinder 26 are simultaneously installed on it. The guide mounting post 25 and the arc-shaped clamping plate 39 move synchronously until the arc-shaped rubber airbag 40 on the arc-shaped clamping plate 39 contacts the shock absorber, completing the compression clamping. The arc-shaped rubber airbag 40 deforms under compression, which is suitable for the compression clamping of irregularly shaped shock absorbers, expanding the applicable range of shock absorber clamping.

[0055] Multiple sets of arc-shaped clamping plates 39 and arc-shaped rubber airbags 40 can provide multiple independent clamping forces. The guide mounting post 25 slides in the guide mounting cylinder 26. At this time, the reset mounting plate 32 pulls the reset spring 33. Under the action of the reset spring 33, the guide mounting post 25 can provide an adaptive clamping force to the arc-shaped rubber airbag 40 through the arc-shaped clamping plates 39, ensuring that the shock absorber can be stably clamped on the clamping mounting plate 3.

[0056] Then, the snap-fit ​​ball 20 is inserted into the snap-fit ​​groove 19. During the insertion process, the snap-fit ​​ball 20 first abuts against the limiting arc protrusion, pushing the guide telescopic column 22 to squeeze the telescopic spring column 23 along the guide telescopic groove 21 until the snap-fit ​​ball 20 passes through the limiting arc protrusion. At this time, under the elastic reset of the telescopic spring column 23, the guide telescopic column 22 and its upper limit arc protrusion 41 are pushed to fix on the snap-fit ​​ball 20, thereby limiting the snap-fit ​​ball 20 and fixing the clamping mounting plate 3 on the combined mounting plate 1.

[0057] Example 3, based on Example 2, please refer to... Figure 1 , Figure 2 , Figures 8-10In this embodiment of the invention, the displacement strength detection module includes a limiting rotation block 17 that is configured to cooperate with the limiting rotation groove 18. The limiting rotation block 17 is provided with a displacement mounting plate 2 that extends out of the limiting rotation groove 18. Locking mounting plates 38 are symmetrically arranged on both sides of the displacement mounting plate 2. Locking screw cylinders 29 are provided through the locking mounting plates 38. Locking studs 30 are provided in cooperation with the locking screw cylinders 29.

[0058] The end of the displacement mounting plate 2 is provided with a transmission mounting plate 15, the end of the transmission mounting plate 15 is provided with a transmission mounting bracket 37, a transmission rotating column 36 is rotatably provided on the transmission mounting bracket 37, a transmission rotating rod 14 is provided on one side of the transmission rotating column 36, a connecting mounting plate 13 is provided between the two transmission rotating rods 14, a synchronous drive telescopic column 5 is symmetrically provided on both sides of the connecting mounting plate 13, a connecting mounting bracket 34 is provided at the outer end of each synchronous drive telescopic column 5, and the transmission rotating rods 14 on both sides are rotatably connected to the connecting mounting brackets 34 on both sides through the connecting rotating column 35 provided at the end;

[0059] An arc-shaped mounting plate 6 is provided between a pair of adjacent connecting mounting plates 13. A steering drive component 8 is provided in the middle of the arc-shaped mounting plate 6. A loading mounting frame 9 is provided at the outer end of the steering drive component 8. A loading mounting hole 10 is provided on the loading mounting frame 9.

[0060] An arc-shaped reinforcing column 7 is provided on one side of the arc-shaped mounting plate 6. A hydraulic drive unit 11 is embedded in the arc-shaped reinforcing column 7. Hydraulic hoses 12 are symmetrically arranged at both ends of the hydraulic drive unit 11. The hydraulic hoses 12 pass through the connecting mounting plates 13 on both sides of the arc-shaped mounting plate 6 in sequence and are connected to the synchronous drive telescopic column 5 on the connecting mounting plate 13.

[0061] By rotating the locking stud 30 in conjunction with the locking cylinder 29, the locking stud 30 moves away from the combined mounting plate 1. At this time, with the cooperation of the limiting rotating block 17 and the limiting rotating groove 18, the displacement mounting plate 2 is rotated and displaced to adapt to the installation of shock absorbers of different sizes. After the shock absorber is clamped and installed, the displacement mounting plate 2 is reset. At this time, the locking stud 30 is rotated in the opposite direction, so that the locking stud 30 moves axially within the locking cylinder 29 and abuts against the combined mounting plate 1 to achieve compression and limiting.

[0062] The loading mounting bracket 9 is fixed to the externally installed fixed equipment through the loading mounting hole 10. At this time, the angle of the detection equipment can be realized by the steering drive component 8. The transmission rotating column 36 causes the transmission rotating rod 14 to rotate a certain angle. At the same time, the angle between the transmission rotating column 36 and the synchronous drive telescopic column 5 is adjusted by the connecting rotating column 35, so that the shock absorber can be adjusted at will within a certain spatial angle. Finally, the synchronous drive telescopic column 5 is adjusted synchronously to change the shock absorber's damping strength performance under different spatial angles, simulating the shock absorber's damping strength performance under actual working conditions. The damping strength detection has strong authenticity.

[0063] The hydraulic drive unit 11 drives the synchronous telescopic column 5 synchronously through the hydraulic hose 12, ensuring the stability of the force applied to the shock absorber's strength detection.
