Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically to a fixture for testing the destructive performance of a suspension system support arm. Background Technology

[0002] The trailing arm is a crucial component of the suspension system, primarily serving to support and secure the engine or vehicle body. Connected to the body or engine via elastic elements (such as rubber bushings), it absorbs and dampens vibrations and shocks generated during engine operation, ensuring ride comfort. Trailing arm breakage is the most severe form of damage. It causes the engine or body to lose support, seriously impacting vehicle safety and reliability.

[0003] The trailing arm failure performance test fixture for suspension systems is a specialized tool used to test the failure performance of automotive powertrain suspension arms. This fixture is designed to simulate the stress conditions experienced by the trailing arm in actual use, evaluating its failure performance by applying specific loads, thereby ensuring the reliability and safety of the suspension system.

[0004] The existing test fixture can only meet the destructive performance test of one support arm. Due to the diversity of support arms, each support arm requires a set of fixtures to be processed, which greatly increases the processing time and processing cost, wastes a lot of manpower and material resources, and seriously delays the progress of the entire test.

[0032] Please see Figure 1-3 As shown, this embodiment of the utility model provides a suspension system support arm destructive performance test fixture, including a base 1, a connecting seat 2, and a clamp 4. Please refer to [link to relevant documentation]. Figure 1 As shown, the base 1 includes a base plate 11 and frame 12 symmetrically arranged on both edges of the base plate 11. Preferably, a support column 5 is fixedly connected between the ends of the two frame 12 away from the base 1 to improve the stability of the base 1. The base plate 11 and the frame 12 on both edges of the base plate 11 form a U-shaped structure with flat surfaces, so that each surface of the base 1 can be placed stably on the test platform, thereby enabling comprehensive destructive performance testing of the support arm 3 in the x-axis, y-axis and z-axis directions, improving the reliability of the test.

[0033] Please see Figure 2 As shown, the connecting seat 2 is detachably and fixedly mounted on the base plate 11. The mounting position of the connecting seat 2 on the base plate 11 is adjustable to accommodate the installation requirements of different types of support arms 3. One end of the support arm 3 with the mounting hole 31 is detachably and fixedly mounted on the connecting seat 2. Different types of support arms 3 can be installed on the connecting seat 2. The clamp 4 is detachably and fixedly sleeved on the end of the support arm 3 away from the connecting seat 2. The pressure head of the testing machine performs destructive performance tests on the support arm 3 from multiple directions of the clamp 4.

[0034] The test fixture of this utility model can meet the installation requirements of different types of support arms 3. One fixture can be used for multiple support arms 3, improving the versatility of the test fixture, greatly reducing the processing time and cost of the test fixture, saving a lot of manpower and material resources, and significantly improving the progress of the entire test. In addition, the test fixture adopts a modular design of base 1, connecting seat 2 and clamp 4, which is convenient and quick to install, and also facilitates the maintenance of each module.

[0035] Further, please refer to Figure 3As shown, a number of neatly arranged countersunk holes 111 are evenly distributed on one side of the base plate 11, and a number of neatly arranged threaded holes 21 are evenly distributed on the connecting seat 2. The threaded holes 21 correspond one-to-one with the countersunk holes 111, and the mounting holes 31 correspond one-to-one with the threaded holes 21. It should be noted that the number of columns and rows of countersunk holes 111 is greater than the number of columns and rows of threaded holes 21, which allows the mounting position of the connecting seat 2 on the base plate 11 to be adjusted. The number of columns and rows of threaded holes 21 is greater than the number of columns and rows of mounting holes 31 of the support arm 3, which allows different types of support arms 3 to be installed on the connecting seat 2.

[0036] Further, please refer to Figure 3 As shown, a bottom through groove 112 is provided on the side of the base plate 11 away from the connecting seat 2, through which the pressure head of the testing machine passes to press against the clamp 4. An edge through groove 121 is provided on the frame 12, through which the pressure head of the testing machine passes to press against the clamp 4. Preferably, two edge through grooves 121 are symmetrically provided on each frame 12. By providing the bottom through groove 112 and the edge through groove 121, the pressure head of the testing machine can press against all surfaces of the clamp 4, thereby enabling comprehensive destructive performance testing of the support arm 3 in the x, y, and z axes, improving the reliability of the test and meeting customer requirements.

[0037] Please see Figure 2 As shown, the chuck 4 has a regular hexahedral structure, with a blind mounting groove 41 on one side that matches the end of the corresponding support arm 3 away from the connecting seat 2. Each support arm 3 uses a corresponding chuck 4, and the chuck 4 is fixedly sleeved on the corresponding support arm 3 through the blind mounting groove 41. Preferably, in addition to the side with the blind mounting groove 41, the other five sides of the chuck 4 have positioning grooves 42 that match the pressure head of the testing machine, improving the stability during the test.

[0038] The working principle of this utility model:

[0039] First, the support arm 3 is bolted to the corresponding threaded hole 21 of the connecting seat 2 according to the mounting hole 31, so that the support arm 3 and the connecting seat 2 are connected as one unit. It is then placed on the base 1 in the corresponding direction of the test. The mounting hole 31 and the threaded hole 21 are aligned one by one with the countersunk hole 111 on the base 1. The support arm 3, the connecting seat 2 and the base 1 are then connected as one unit using bolts. Then the pressure head of the testing machine can press against the positioning groove 42 on the corresponding surface of the chuck 4 to conduct the test. The position of the base 1 can be adjusted so that different surfaces of the chuck 4 correspond to the pressure head of the testing machine, thereby conducting a comprehensive destructive performance test on the support arm 3 from all directions.

[0040] The preferred embodiments of this utility model have been described in detail above and should not be considered as limiting the scope of this utility model. All equivalent changes and improvements made within the scope of the claims of this utility model should still fall within the patent coverage of this utility model.
