Description

Technical Field

[0001] This invention relates to the field of suspension strength testing technology, specifically to an automotive suspension strength testing platform. Background Technology

[0002] As a crucial force transmission system connecting the vehicle body and wheels, the automotive suspension system transmits forces and torques between the wheels and the chassis, buffers impacts and vibrations from uneven road surfaces, and ensures vehicle ride comfort, handling stability, and safety. The strength, durability, and reliability of the suspension system directly affect the overall vehicle's ride quality and occupant safety. Strength and fatigue durability testing of the suspension system is an essential verification step in vehicle development, component certification, and production quality control. Conventional suspension strength testing typically involves simulating actual load conditions on a testing platform, applying alternating or constant loads to the suspension assembly to assess its structural integrity, material fatigue characteristics, and service life.

[0003] Currently, most common suspension strength testing equipment is fixed or single-station structure. Its workflow is generally as follows: the suspension assembly to be tested is manually installed onto the loading device of the testing platform → the equipment is started to perform a pre-programmed loading test → the load is unloaded after the test is completed → the tested suspension is manually disassembled → the next suspension to be tested is installed. This process has the following significant shortcomings:

[0004] 1. Low testing efficiency: Because the installation and disassembly of the test piece and the actual loading test process must be carried out sequentially, the equipment has a large amount of idle time outside of testing. Especially for samples requiring long-term fatigue testing, the waiting time of the equipment after a single test cycle is particularly significant, which seriously restricts the testing throughput and cannot meet the needs of modern industrial production for large-volume, fast-paced testing.

[0005] 2. High reliance on manual operation and discontinuous rhythm: The entire "test-sample change" cycle relies heavily on manual intervention by operators. The speed and proficiency of personnel directly affect equipment utilization, and human factors can easily introduce installation errors or cause fluctuations in interval time, making it difficult to achieve standardized, continuous, and efficient testing operations.

[0006] 3. Low equipment utilization: During the interval of waiting for workpiece replacement, the expensive loading drive system (such as hydraulic actuators, motors, etc.) and data acquisition system are idle, resulting in waste of equipment resources and low output per unit time.

[0007] To address the aforementioned issues and improve the overall efficiency and automation level of suspension strength testing, a new testing platform capable of parallel operation of "testing" and "assembly / disassembly" processes is urgently needed. By optimizing the platform's structural design, it is possible to perform strength testing on one suspension while simultaneously preparing for the installation or disassembly of another, thereby minimizing workstation switchover time and achieving seamless integration of the testing process. This is of great significance for increasing testing center capacity, reducing unit testing costs, and adapting to the demands of modern intelligent manufacturing. Summary of the Invention

One end of the limiting groove is provided with an installation groove. The interior of the movable seat is symmetrically and slidably connected to the two sides of the installation groove. One end of the connecting plate extends into the inner cavity of the installation groove, and the other end of the connecting plate extends into the outer wall of the movable seat. A connecting block is fixedly connected to the bottom end of the connecting plate. A connecting spring is connected between the connecting block and the movable seat. A reinforcing frame is slidably connected to the interior of the movable seat below the connecting block. A rotating column is rotatably connected to the bottom end of the movable seat.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. Parallel operation of testing and sample change is achieved, greatly improving testing efficiency: This invention, through an innovative rotatable dual-station design (rotating seat and symmetrically arranged limiting frames and movable seats), transforms the traditional serial "test → stop → disassemble → install → retest" process into a parallel "test on one side, sample change on the other" mode. When the suspension at one station is undergoing strength testing, the operator can simultaneously disassemble the tested sample and prepare for the installation of the sample to be tested at the other station. After the current test is completed, the two stations can be quickly rotated and exchanged via the drive mechanism, allowing immediate commencement of testing on the newly installed sample. This virtually eliminates the idle time of equipment waiting for sample change, significantly improving the continuous operation capability of the testing platform and the testing throughput per unit time.

[0021] 2. Optimized workflow, reducing manual operation intensity and interval fluctuations: Through the linkage design of the detection mechanism and the rotary positioning mechanism (such as the hydraulic cylinder-driven push frame also serving as the positioning frame unlocking trigger device), automatic locking during testing and automatic unlocking rotation after testing are achieved. This reduces the number of manual intervention steps, making station switching operations fast, accurate, and standardized. The operator's main work is concentrated on sample assembly and disassembly within a relatively relaxed time frame, avoiding the urgent operation of waiting for the test to end next to the equipment, reducing labor intensity, and making the work rhythm more controllable and stable.

[0022] 3. Improved overall utilization and return on investment of expensive testing equipment: By effectively reducing non-testing time, core testing resources such as the hydraulic loading system and data acquisition system can remain in effective working condition for a longer period. This significantly improves the overall equipment utilization (OEE), enabling the same equipment investment to complete more testing tasks, reducing the testing cost per product, and resulting in significant economic benefits.

[0023] 4. Integrating a convenient and reliable quick-clamping mechanism ensures both testing quality and operational safety: This invention provides a dual guarantee of quick clamping and rigid locking for the suspension mounting plate through its installation mechanism (including a connecting plate, connecting spring, reinforcing frame, and threaded drive assembly). At the testing station, the mechanism automatically strengthens the locking to prevent loosening during testing, ensuring accurate transmission of load force and data reliability. At the sample change station, the mechanism can release the locking and provides space for disassembly, facilitating rapid operation. This design ensures both the rigor of the testing process and the convenience of sample change.

[0024] In summary, this invention, through structural innovation and process reengineering, successfully solves the prominent problem of efficiency bottleneck in traditional suspension strength testing platforms, achieving a leapfrog improvement in testing efficiency and optimization of the work process, while ensuring the reliability and ease of operation of the testing process. It has significant practical value for improving the automation level and production cycle of the automotive parts testing industry. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0037] Please see Figures 1 to 9 In this embodiment of the invention, the vehicle suspension strength testing platform includes a base 1, a fixed seat 2 fixedly connected to the top of the base 1, a rotating seat 3 rotatably connected to the top of the fixed seat 2, a limiting frame 4 symmetrically fixedly connected to the outer wall of the rotating seat 3, a movable seat 5 slidably connected to the inner wall of the limiting frame 4, an mounting plate 6 installed on the outer wall of the movable seat 5, a vehicle suspension installed at the bottom of the mounting plate 6, a limiting plate 9 fixedly connected to the inner cavity of the limiting frame 4 on the outer wall of the rotating seat 3, a limiting groove 10 opened on the outer wall of the movable seat 5, and the limiting plate 9 slidably connected to the inner wall of the limiting groove 10. The base 1 generates continuous vibration on the vehicle suspension through the testing mechanism 7, and the mounting plate 6 is installed on the outer wall of the movable seat 5 through the mounting mechanism 8.

[0038] The detection mechanism 7 includes a groove 701, which is located at the top of the base 1. Two hydraulic cylinders 702 are installed at the bottom of the inner wall of the groove 701. The output end of the hydraulic cylinders 702 is connected to a push frame 703. The detection mechanism 7 also includes a motor 704, which is installed inside the base 1. The output end of the motor 704 is connected to a first spur gear 705. A second spur gear 706 is rotatably connected to the outer wall of the first spur gear 705 inside the base 1. A rotating shaft 707 is fixedly connected to the top of the second spur gear 706. The top of the rotating shaft 707 is fixedly connected to a rotating seat 3. A positioning groove 708 is symmetrically provided at the bottom of the rotating seat 3. A positioning frame 709 is symmetrically slidably connected inside the base 1 and the fixed seat 2. The top of the positioning frame 709 extends above the fixed seat 2, and the bottom of the positioning frame 709 extends into the inner cavity of the groove 701. A positioning spring 710 is connected between the positioning frame 709 and the base 1.

[0039] In this embodiment, the vehicle suspension is fixedly connected to the mounting plate 6, simulating the actual installation method. The mounting plate 6 needs to have mounting holes opened at corresponding positions as required to meet assembly needs. A clamping assembly matching the upper end of the vehicle suspension can also be provided on the mounting plate to achieve a secure fixation and prevent the vehicle suspension from loosening during testing. Furthermore, the vehicle suspension shown in the illustration is a schematic structure; the actual structure of the object being tested will prevail during the actual testing process.

[0040] In use, the hydraulic cylinder 702 rotates to drive the pusher 703 to move upward. The pusher 703 moves upward and comes into contact with the vehicle suspension. The vehicle suspension pushes the mounting plate 6 and the movable seat 5 to move upward. After moving a certain distance, the hydraulic cylinder 702 rotates to drive the pusher 703 to move up and down repeatedly. The displacement of the pusher 703 causes the vehicle suspension to vibrate. At this time, the movable seat 5 slides up and down in the limit frame 4, and the limit plate 9 slides on the inner wall of the limit groove 10.

[0041] During testing, the pusher 703 is located outside the groove 701, and the positioning frame 709 is engaged in the positioning groove 708 by the elastic force of the positioning spring 710, fixing the fixed seat 2 and the rotating seat 3 to prevent the rotating seat 3 from rotating. After testing, the pusher 703 moves into the groove 701, contacts the positioning frame 709, pushes the positioning frame 709 to move, compresses the positioning spring 710, and the positioning frame 709 moves out of the positioning groove 708, releasing the fixation of the rotating seat 3. At this time, the motor 704 is started, and the motor 704 drives the first spur gear 705 to rotate. The rotation of the first spur gear 705 drives the second spur gear 706 to rotate. The rotation of the second spur gear 706 drives the rotating shaft 707 to rotate. The rotation of the rotating shaft 707 drives the rotating seat 3 to rotate. The rotation of the rotating seat 3 causes the two sides of the rotating seat 3 to exchange, and then the testing operation is performed again on the other side of the car suspension that has been installed. This design allows for simultaneous disassembly and installation of the suspension on the other side while inspecting the suspension on one side of the rotating seat 3, reducing the interval between the two inspections and improving the efficiency of vehicle suspension inspection.

[0042] Please refer to this carefully. Figures 5 to 9 The mounting mechanism 8 includes a transverse groove 801, which is symmetrically formed on the outer wall of the limiting frame 4. The top of the fixed seat 2 is provided with a circular groove 802 located on the outside of the rotating shaft 707. The bottom of the rotating seat 3 is symmetrically rotatably connected to the two sides of the rotating shaft 707 with a third spur gear 803. The top of the third spur gear 803 is fixedly connected with a first threaded rod 804. A C-shaped frame 805 is slidably connected inside the rotating seat 3. The first threaded rod 804 passes through the C-shaped frame 805. The two ends of the C-shaped frame 805 are respectively in contact with the bottom ends of the two movable seats 5. The mounting plate 6 is symmetrically provided with connecting grooves 806 on both sides. The outer wall of the movable seat 5 is open at the end away from the limiting groove 10. The movable seat 5 is provided with a mounting groove 807. Connecting plates 808 are symmetrically slidably connected to both sides of the mounting groove 807 inside the movable seat 5. One end of the connecting plate 808 extends into the inner cavity of the mounting groove 807, and the other end of the connecting plate 808 extends into the outer wall of the movable seat 5. A connecting block 809 is fixedly connected to the bottom end of the connecting plate 808. A connecting spring 810 is connected between the connecting block 809 and the movable seat 5. A reinforcing frame 811 is slidably connected to the interior of the movable seat 5 below the connecting block 809. A rotating column 813 is rotatably connected to the bottom end of the movable seat 5. A second threaded rod 812 is fixedly connected to the top end of the rotating column 813. The second threaded rod 812 passes through the reinforcing frame 811.

[0043] In this embodiment: When installing the mounting plate 6, the mounting plate 6 is inserted into the mounting groove 807. At this time, the connecting block 809 is displaced by the elastic force of the connecting spring 810. The displacement of the connecting block 809 causes the connecting plate 808 to move into the connecting groove 806, thus limiting the mounting plate 6. Then, the rotating column 813 is rotated, which drives the second threaded rod 812 to rotate. The rotation of the second threaded rod 812 causes the reinforcing frame 811 to move. The reinforcing frame 811 moves and contacts the connecting block 809, making the connecting block 809 unable to move, thereby fixing the mounting plate 6 and the movable seat 5.

[0044] When the car suspension above the push frame 703 rotates to the other side of the rotating seat 3, the rotating seat 3 rotates and drives the third spur gear 803 to move along the circular groove 802, thereby driving the third spur gear 803 to rotate. The rotation of the third spur gear 803 drives the first threaded rod 804 to rotate. The rotation of the first threaded rod 804 drives the C-shaped frame 805 to move. The displacement of the C-shaped frame 805 pushes the movable seat 5 to move upward. After the rotating seat 3 has finished rotating, the C-shaped frame 805 pushes the movable seat 5 to the top of the inner wall of the limiting frame 4, thereby fixing the movable seat 5 and facilitating the disassembly and assembly of the mounting plate 6.

[0045] When the movable seat 5 moves to the top of the inner wall of the limiting frame 4, the connecting plate 808 moves to the transverse groove 801, giving the connecting plate 808 room to move, thus allowing the mounting plate 6 to be disassembled. When the movable seat 5 moves away from the top of the inner wall of the limiting frame 4, the connecting plate 808 contacts the inner wall of the limiting frame 4, leaving the connecting plate 808 with no room to move, thus further reinforcing the mounting plate 6 and preventing the car suspension from loosening during testing. At the same time, it facilitates the quick removal of the mounting plate 6 from the movable seat 5, thereby enabling quick disassembly and assembly of the car suspension.

[0046] Please refer to this carefully. Figures 1 to 9 The outer wall of the limiting plate 9 is in contact with the inner wall of the limiting groove 10. The limiting plate 9 is a strip rod with a dovetail or trapezoidal cross-section.

[0047] In this embodiment: when the movable seat 5 slides within the limiting frame 4, the limiting plate 9 slides within the limiting groove 10 to limit the movement direction of the movable seat 5, so that the movable seat 5 can only slide up and down.

[0048] Please refer to this carefully. Figures 1 to 4 The first spur gear 705 meshes with the second spur gear 706.

[0049] In this embodiment: the motor 704 drives the first spur gear 705 to rotate, the first spur gear 705 drives the second spur gear 706 to rotate, the second spur gear 706 drives the rotating shaft 707 to rotate, and the rotating shaft 707 drives the rotating seat 3 to rotate.

[0050] Please refer to this carefully. Figures 1 to 4 The inner wall of the positioning groove 708 fits against the top outer wall of the positioning frame 709.

[0051] In this embodiment: When testing is performed, the push frame 703 is located outside the groove 701, and the positioning frame 709 is engaged in the positioning groove 708 by the elastic force of the positioning spring 710, fixing the fixed seat 2 and the rotating seat 3 to prevent the rotating seat 3 from rotating; when the testing is completed, the push frame 703 moves into the groove 701, and the push frame 703 comes into contact with the positioning frame 709, pushing the positioning frame 709 to move, causing compression on the positioning spring 710, and the positioning frame 709 moves out of the positioning groove 708, thus releasing the fixation of the rotating seat 3.

[0052] Please refer to this carefully. Figures 5 to 9 The inner wall of the circular groove 802 is provided with toothed grooves, which mesh with the third spur gear 803.

[0053] In this embodiment: the rotating seat 3 rotates, causing the third spur gear 803 to move along the circular groove 802, thereby causing the third spur gear 803 to rotate.

[0054] Please refer to this carefully. Figures 5 to 9 The outer wall of the C-shaped frame 805 is provided with a first threaded hole, which matches the first threaded rod 804.

[0055] In this embodiment: the rotation of the third spur gear 803 drives the first threaded rod 804 to rotate, and the rotation of the first threaded rod 804 drives the C-shaped frame 805 to move.

[0056] Please refer to this carefully. Figures 5 to 9 The outer wall of the mounting plate 6 is in contact with the inner wall of the mounting groove 807, and one end of the connecting plate 808 is semi-circular, with the outer wall of one end of the connecting plate 808 in contact with the inner wall of the connecting groove 806.

[0057] In this embodiment: the mounting plate 6 is inserted into the mounting groove 807. At this time, the connecting block 809 is displaced by the elastic force of the connecting spring 810. The displacement of the connecting block 809 causes the connecting plate 808 to move into the connecting groove 806.

[0058] Please refer to this carefully. Figures 5 to 9The reinforcing frame 811 is C-shaped and has a second threaded hole on its outer wall. Both ends of the reinforcing frame 811 are provided with inclined surfaces, which are in contact with the connecting block 809. The second threaded hole matches the second threaded rod 812.

[0059] In this embodiment: Rotating the rotating column 813 causes the second threaded rod 812 to rotate, and the rotation of the second threaded rod 812 causes the reinforcing frame 811 to move. The reinforcing frame 811 moves and comes into contact with the connecting block 809, so that the connecting block 809 cannot move.

[0060] It should be noted that, according to the technical solution disclosed in this patent document, the detection process involved in this invention, such as the detection method of applying continuous reciprocating load to the automobile suspension by driving a pusher frame with a hydraulic cylinder to simulate vibration fatigue, and the specific structure and signal acquisition principle of the smoke detection sensor, temperature sensor, pressure sensor, or other conventional detection sensors used in this process, are all well-known technologies and mature methods widely used in suspension strength and durability testing in this field. Such detection processes and sensor configurations are common in existing testing equipment and technical literature, and are not the core content to be protected by this invention. The innovation of this invention lies in providing a novel dual-station parallel operation mechanical structure and process control method to solve the problems of low equipment utilization and detection efficiency, rather than improving basic detection principles or general sensors.
