Description

Technical Field

[0001] This utility model relates to the field of automotive parts testing technology, and in particular to an automotive parts durability testing device. Background Technology

[0002] In the automotive safety system, the braking system plays a crucial role, and the brake discs and brake pads, as the core components of the braking system, directly determine the service life and safety performance of the braking system. With the rapid development of the automotive industry, the market's quality requirements for automotive braking systems are increasing. Therefore, it is particularly necessary to conduct rigorous durability testing on brake discs and brake pads after production.

[0003] Currently, existing automotive brake disc and pad durability testing equipment has certain shortcomings in its use. During prolonged testing, some devices generate significant heat due to continuous friction between the brake disc and pads, and the equipment itself lacks an effective heat dissipation mechanism, resulting in the brake disc and pads operating in a high-temperature environment. This high temperature not only alters the physical properties of the brake disc and pads, affecting the accuracy of test results and preventing the test data from accurately reflecting their durability in actual use, but it may also shorten the lifespan of the brake disc and pads, and even cause the testing equipment to malfunction, increasing testing costs and safety hazards. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a durability testing device for automotive parts.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A durability testing device for automotive parts includes a workbench. A drive rod is rotatably connected to the upper end of the workbench, and a brake disc is coaxially fixedly connected to the upper end of the drive rod. A brake pad is mounted on the upper end of the workbench, and the brake pad cooperates with the brake disc. A motor is fixedly connected to the lower end of the workbench, and the output shaft of the motor is fixedly connected to the lower end of the drive rod. A heat dissipation mechanism for cooling the brake disc and brake pad is provided on the upper end of the workbench. The heat dissipation mechanism includes a fixing block fixedly connected to the upper end of the workbench, and a crossbar rotatably connected to the side wall of the fixing block. A fan blade is fixedly sleeved at the end of the crossbar near the brake disc.

[0007] Preferably, a vertical rod is rotatably connected through the workbench, and a second bevel gear is fixedly sleeved on the upper end of the vertical rod.

[0008] Preferably, a first bevel gear is fixedly sleeved on the crossbar, and the first bevel gear meshes with a second bevel gear.

[0009] Preferably, the output shaft of the motor and the lower end of the vertical rod are both fixedly fitted with synchronous pulleys, and the two synchronous pulleys are connected by a synchronous belt drive.

[0010] Preferably, a brake pad controller is installed at the lower end of the workbench, and the brake pad controller is electrically connected to the brake pads.

[0011] Preferably, the lower end of the workbench is fixedly connected to four bases, which are arranged in a rectangular pattern.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. By setting up a dedicated heat dissipation mechanism, the motor power is used to drive the fan blades to rotate through the transmission of synchronous pulleys, synchronous belts, vertical rods, bevel gears (first bevel gear and second bevel gear) and horizontal rods to generate airflow, which dissipates heat and cools the brake discs and brake pads during the test. This effectively avoids the high temperature caused by friction from changing the physical properties of the brake discs and brake pads, ensuring the accuracy of the test results, improving the reliability of the test data, and truly reflecting the durability of the brake discs and brake pads in actual use.

[0014] 2. The heat dissipation mechanism of this utility model is powered by a motor that drives the brake disc to rotate, eliminating the need for an additional power device. This simplifies the structure of the device, reduces manufacturing costs and energy consumption, and enables the heat dissipation mechanism to work synchronously with the rotation of the brake disc, ensuring the timeliness and stability of the heat dissipation effect and further improving the practicality of the device.

[0015] 3. A brake pad controller is installed, which can precisely control the working state of the brake pads according to different testing requirements, such as contact pressure and contact frequency. It can simulate a variety of different braking conditions, improving the flexibility and comprehensiveness of the test, making the test results more valuable, and meeting the durability testing needs of brake discs and brake pads of different specifications and performance requirements.

[0022] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0023] Reference Figure 1-5 A durability testing device for automotive parts includes a workbench 1. A drive rod 7 is rotatably connected to the upper end of the workbench 1, and a brake disc 4 is coaxially fixedly connected to the upper end of the drive rod 7. Rotation of the drive rod 7 can drive the brake disc 4 to rotate synchronously, simulating the rotation state of the brake disc 4 during vehicle operation. Brake pads 3 are installed on the upper end of the workbench 1, and the brake pads 3 cooperate with the brake disc 4. During the test, the brake pads 3 and brake disc 4 come into contact and rub against each other, simulating the working scenario of vehicle braking, thereby achieving the durability test of both.

[0024] A motor 6 is fixedly connected to the lower end of the workbench 1. The output shaft of the motor 6 is fixedly connected to the lower end of the drive rod 7. The motor 6 serves as a power source. After the motor 6 is started, its output shaft rotates, which drives the drive rod 7 to rotate, thereby providing power for the rotation of the brake disc 4. A heat dissipation mechanism is provided at the upper end of the workbench 1 to dissipate heat from the brake disc 4 and brake pads 3. This heat dissipation mechanism can promptly remove the heat generated by friction between the brake disc 4 and brake pads 3 during the test, preventing high temperatures from affecting the test results and component performance.

[0025] The heat dissipation mechanism includes a fixed block 5 fixedly connected to the upper end of the workbench 1. A crossbar 13 is rotatably connected to the side wall of the fixed block 5. The fixed block 5 provides stable support for the crossbar 13, ensuring that the crossbar 13 can rotate smoothly. A fan blade 11 is fixedly sleeved at the end of the crossbar 13 near the brake disc 4. When the crossbar 13 rotates, the fan blade 11 rotates accordingly, generating airflow. The airflow blows towards the brake disc 4 and brake pads 3, achieving heat dissipation and cooling for both, simulating the heat dissipation effect achieved by airflow passing through the brake disc 4 during car operation.

[0026] A vertical rod 14 is rotatably connected through the worktable 1, allowing it to rotate freely on the worktable 1. A second bevel gear 12 is fixedly sleeved at the upper end of the vertical rod 14, and a first bevel gear 9 is fixedly sleeved on the horizontal rod 13. The first bevel gear 9 meshes with the second bevel gear 12. Through the meshing transmission of the first bevel gear 9 and the second bevel gear 12, the rotation of the vertical rod 14 can drive the horizontal rod 13 to rotate synchronously, thereby providing power for the rotation of the fan blade 11.

[0027] Both the output shaft of motor 6 and the lower end of vertical rod 14 are fixedly fitted with synchronous pulleys 15, which are connected by a synchronous belt 10. After motor 6 starts, its output shaft rotates, driving the synchronous pulley 15 connected to it to rotate. Under the transmission action of synchronous belt 10, the other synchronous pulley 15 rotates accordingly, thereby driving vertical rod 14 to rotate, realizing the transmission of power from motor 6. This allows the heat dissipation mechanism to work synchronously with the rotation of brake disc 4, ensuring the timeliness and stability of heat dissipation.

[0028] A brake pad controller 8 is installed at the lower end of the workbench 1. The brake pad controller 8 is electrically connected to the brake pad 3. The working state of the brake pad 3 can be precisely controlled through the brake pad controller 8, such as the contact pressure and contact frequency between the brake pad 3 and the brake disc 4. This allows for the simulation of different braking conditions according to different testing requirements, thereby improving the flexibility and reliability of the test.

[0029] Four bases 2 are fixedly connected to the lower end of the workbench 1. The four bases 2 are arranged in a rectangular shape. The bases 2 provide stable support for the entire testing device, preventing the device from shaking during the test and ensuring the smooth progress of the test. At the same time, the rectangular distribution design can make the force on the device more uniform and improve the overall stability of the device.

[0030] When using this utility model, when conducting durability tests on brake disc 4 and brake pad 3 using this automotive parts durability testing device, firstly, the brake disc 4 to be tested is coaxially and fixedly connected to the upper end of the drive rod 7 to ensure that the brake disc 4 can rotate stably with the drive rod 7. Then, the brake pad 3 is installed on the upper end of the workbench 1, and the position of the brake pad 3 is adjusted so that it cooperates with the brake disc 4.

[0031] When motor 6 is started, its output shaft begins to rotate. On one hand, the output shaft of motor 6 directly drives the drive rod 7 to rotate, which in turn drives the brake disc 4 to rotate, simulating the rotation of the brake disc 4 during vehicle operation. On the other hand, the output shaft of motor 6 drives the synchronous pulley 15, which is fixedly sleeved with it, to rotate. Under the transmission action of the synchronous belt 10, the synchronous pulley 15 at the lower end of the vertical rod 14 rotates accordingly, thereby driving the vertical rod 14 to rotate. When the vertical rod 14 rotates, the second bevel gear 12, which is fixedly sleeved at its upper end, rotates synchronously. Since the second bevel gear 12 meshes with the first bevel gear 9, which is fixedly sleeved on the horizontal rod 13, the rotation of the second bevel gear 12 drives the first bevel gear 9 to rotate, which in turn causes the horizontal rod 13 to rotate. The rotation of the horizontal rod 13 drives the fan blade 11 at its end to rotate. The rotation of the fan blade 11 generates airflow, which blows towards the brake disc 4 and brake pad 3, promptly carrying away the heat generated by friction between them, achieving heat dissipation and cooling, simulating the heat dissipation effect achieved by airflow passing through the brake disc 4 during vehicle operation.

[0032] Simultaneously, according to the testing requirements, the brake pads 3 are controlled by the brake pad controller 8 at the lower end of the workbench 1. The contact pressure and frequency between the brake pads 3 and the brake disc 4 are adjusted to simulate different braking conditions, causing the brake pads 3 to rub against the rotating brake disc 4 for durability testing. During the test, the wear and working condition of the brake disc 4 and brake pads 3 are continuously observed, and relevant test data are recorded until the preset time or number of tests is reached, completing the durability test of the brake disc 4 and brake pads 3.

[0033] Throughout the test, the four rectangular bases 2 at the bottom of the workbench 1 provide stable support for the device, ensuring that the device will not shake and guaranteeing the stability of the test and the accuracy of the test results.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
