Description

Technical Field

[0001] This utility model relates to the field of test bench technology, and in particular to a brake caliper durability test bench. Background Technology

[0002] Brake caliper durability testing simulates various operating conditions of automotive brake calipers during actual use. This testing requires a series of equipment, including a brake test bench, torque loading device, temperature control system, and data acquisition system. This equipment can simulate various operating conditions in real-world use, applying different loads and stresses to the brake system components. Therefore, the test bench is one of the essential pieces of equipment for brake caliper durability testing and serves as the foundation for the experiment. It provides a stable, safe, and suitable working space for placing experimental instruments, samples, and various experimental materials.

[0003] Different types and specifications of brake calipers differ in structure and size, and test benches may require specialized fixture designs for different calipers. This makes the test bench well adaptable to certain specific models of brake calipers, but may require significant modifications to test other types of brake calipers, thus limiting its versatility. Utility Model Content

[0004] In order to enable the test bench to clamp more specifications of brake calipers, this application provides a brake caliper durability test bench.

[0005] The brake caliper durability testing bench provided in this application adopts the following technical solution:

[0006] A brake caliper durability testing bench includes a test bench body and a clamping device. The clamping device is used to clamp the brake caliper. The clamping device includes a plurality of sliding seats and a driving component. The plurality of sliding seats are slidably connected to the test bench. The driving component is used to drive the sliding of the plurality of sliding seats. A first abutment block is fixedly connected to each of the plurality of sliding seats, and a plurality of second abutment blocks are slidably connected to the plurality of sliding seats along their sliding direction. A spring is provided on each of the plurality of second abutment blocks. The spring always drives the second abutment blocks to slide away from the corresponding sliding seat. When the sliding seat moves toward the brake caliper, the second abutment block abuts against the brake caliper first compared to the first abutment block.

[0007] By adopting the above technical solution, the distance between the first and second abutment blocks and the brake caliper can be adjusted by driving the sliding seat through the drive component. This adapts to the clamping of brake calipers of different sizes and specifications, improving the versatility and applicability of the test bench. When the sliding seat moves towards the brake caliper, the second abutment block contacts the brake caliper first, and a spring is provided on the second abutment block. The spring always drives the second abutment block to slide away from the corresponding sliding seat. In this way, when clamping the brake caliper, the second abutment block can firmly abut against the brake caliper under the action of the spring. Even if the brake caliper undergoes slight displacement due to force during the test, the spring force can keep the second abutment block in close contact with the brake caliper. Together with the first abutment block, they provide a stable and reliable clamping for the brake caliper, ensuring that the brake caliper will not loosen or shift during the test, and guaranteeing the accuracy and reliability of the test results.

[0008] Preferably, it further includes an adjusting screw, one end of which is threadedly connected to a sliding seat along its length, and the other end of which is slidably connected to a second abutment block. The two ends of the spring abut against the adjusting bolt and the second abutment block, respectively.

[0009] By adopting the above technical solution, the adjusting screw, with one end threaded onto the sliding seat, moves along its length during rotation. The other end of the adjusting screw is slidably connected to the second abutment block, and both ends of the spring abut against the adjusting bolt and the second abutment block respectively. Therefore, the movement of the adjusting screw changes the spring's compression level, thus precisely adjusting the spring's preload. Precise adjustment of the spring preload makes the clamping force of the second abutment block on the brake caliper more uniform and stable. During testing, regardless of the direction and magnitude of the force applied to the brake caliper, the clamping device maintains stable clamping of the brake caliper through the elastic deformation of the spring and the fixing effect of the adjusting screw, preventing the brake caliper from shaking or shifting on the test bench, thereby improving the accuracy and reliability of the test results.

[0010] Preferably, a force-applying rod is coaxially and fixedly connected to the adjusting screw, and the end of the force-applying rod away from the adjusting screw passes through a sliding seat to the outside, and the end of the force-applying rod located to the outside is provided with a force-applying handle.

[0011] By adopting the above technical solution, operators can more precisely control the rotation amplitude of the adjusting screw by holding the force application handle, thereby accurately adjusting the preload of the spring and achieving fine adjustment of the clamping force of the brake caliper, ensuring that the clamping effect meets different test requirements.

[0012] Preferably, the first abutment block is tapered from the end near the sliding seat to the end away from the sliding seat.

[0013] By adopting the above technical solution, the brake caliper usually has a certain bevel or arc. The tapered first abutment block can better fit the shape of the brake caliper, improve the adaptability of clamping, and provide a good clamping effect for different models of brake calipers or different parts of the same model of brake caliper, thereby enhancing the versatility and flexibility of the test bench clamping device.

[0014] Preferably, a rubber pad is provided on the side of each of the first and second abutment blocks that contacts the brake caliper.

[0015] By adopting the above technical solution, rubber has a large coefficient of friction. The presence of the rubber pad can increase the friction between the first abutment block and the brake caliper, making the brake caliper more stable after clamping and less prone to slippage or displacement during testing, thereby ensuring the accuracy and reliability of the test. The rubber pad has a certain degree of elasticity and deformation capacity, which can better adapt to the unevenness or shape difference of the brake caliper surface. Even if there are some minor bumps or irregularities on the surface of the brake caliper, the rubber pad can achieve a tight fit through its own deformation, improving the stability and reliability of the clamping.

[0016] Preferably, the driving component is a plurality of hydraulic cylinders, each of the plurality of hydraulic cylinders corresponding to a plurality of sliding seats, each of the plurality of hydraulic cylinders being fixedly connected to the main body of the test bench, and one end of the output shaft of each of the plurality of hydraulic cylinders being fixedly connected to the corresponding sliding seat.

[0017] By adopting the above technical solution, the design of multiple cylinders corresponding to multiple sliding seats allows each sliding seat to be independently controlled and adjusted. This enables flexible adjustment of the position and movement state of each sliding seat according to different testing requirements, adapting to various types and specifications of brake caliper testing, and improving the versatility and adaptability of the test bench. The cylinders can provide stable and large thrust or pull force, ensuring that the sliding seats can move smoothly on the main body of the test bench, thereby driving the brake calipers clamped on the sliding seats to accurately reach the designated position, meeting the requirements for brake caliper position adjustment under different testing conditions.

[0018] Preferably, a protective railing is provided on one side of the main body of the test bench, and a transparent protective plate is installed on the protective railing.

[0019] By adopting the above technical solutions, the protective barrier can prevent personnel from accidentally approaching the test bench during operation, thus preventing injury from moving parts or flying objects. The transparent protective panel not only serves as a barrier but also allows operators to observe the test process from a safe distance, avoiding approaching dangerous areas while observing the test. The transparent panel allows operators to clearly see the interior of the test bench, facilitating real-time monitoring of the test process, timely detection of abnormalities, and appropriate action, thereby improving the accuracy and repeatability of the test.

[0020] The main technical effects of this utility model are reflected in the following aspects:

[0021] 1. This utility model, by setting up a clamping device and driving the sliding seat to slide via a driving component, can adjust the distance between the first and second abutment blocks and the brake caliper, thereby adapting to the clamping of brake calipers of different sizes and specifications, and improving the versatility and applicability of the test bench. When the sliding seat moves towards the brake caliper, the second abutment block abuts against the brake caliper first, and the second abutment block is equipped with a spring, which always drives the second abutment block to slide away from the corresponding sliding seat. In this way, when clamping the brake caliper, the second abutment block can firmly abut against the brake caliper under the action of the spring. Even if the brake caliper undergoes slight displacement due to force during the test, the spring force can keep the second abutment block in close contact with the brake caliper at all times. Together with the first abutment block, they provide a stable and reliable clamping for the brake caliper, ensuring that the brake caliper will not loosen or shift during the test, and guaranteeing the accuracy and reliability of the test results.

[0022] 2. This utility model incorporates an adjusting screw. By rotating the adjusting screw, one end of which is threaded onto a sliding seat, it moves along its length during rotation. The other end of the adjusting screw is slidably connected to a second abutment block, and both ends of the spring abut against the adjusting bolt and the second abutment block respectively. Therefore, the movement of the adjusting screw changes the spring's compression level, thus precisely adjusting the spring's preload. Precise adjustment of the spring preload ensures a more uniform and stable clamping force between the second abutment block and the brake caliper. During testing, regardless of the direction and magnitude of the force applied to the brake caliper, the clamping device maintains stable clamping of the brake caliper through the elastic deformation of the spring and the fixing effect of the adjusting screw, preventing the brake caliper from shaking or shifting on the test bench, thereby improving the accuracy and reliability of the test results.

[0023] 3. By incorporating a rubber pad, this utility model utilizes the high coefficient of friction of rubber to increase the friction between the first contact block and the brake caliper. This makes the brake caliper more stable after clamping, preventing slippage or displacement during testing and ensuring the accuracy and reliability of the test. The rubber pad also possesses elasticity and deformation capacity, allowing it to better adapt to unevenness or shape differences on the brake caliper surface. Even if the brake caliper surface has minor bumps or irregularities, the rubber pad can achieve a tight fit through its own deformation, improving the stability and reliability of the clamping.

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0032] This application discloses a brake caliper durability testing bench.

[0033] Reference Figure 1 , Figure 5 and Figure 6 This embodiment of a brake caliper durability test bench includes a test bench body 1 and a clamping device 2. The clamping device 2 is used to clamp the brake caliper 4. The clamping device 2 includes a plurality of sliding seats 21 and a driving member 22. The plurality of sliding seats 21 are slidably connected to the test bench. The driving member 22 is used to drive the sliding of the plurality of sliding seats 21. A first abutment block 23 is fixedly connected to each of the plurality of sliding seats 21, and a plurality of second abutment blocks 24 are slidably connected to each of the plurality of sliding seats 21 along their sliding direction. It also includes an adjusting screw. The rod 25 has one end threadedly connected to the sliding seat 21 along its length, and the other end slidably connected to the second abutment block 24. Several second abutment blocks 24 are provided with springs 26, with the two ends of the springs 26 abutting against the adjusting bolt and the second abutment block 24 respectively. The springs 26 always drive the second abutment blocks 24 to slide away from the corresponding sliding seat 21. When the sliding seat 21 moves towards the brake caliper 4, the second abutment block 24 abuts against the brake caliper 4 first, compared to the first abutment block 23.

[0034] Reference Figure 2 and Figure 3The sliding seat 21 is driven by the driving component 22 to slide, which adjusts the distance between the first abutment block 23, the second abutment block 24, and the brake caliper 4, thereby accommodating brake calipers 4 of different sizes and specifications, improving the versatility and applicability of the test bench. When the sliding seat 21 moves towards the brake caliper 4, the second abutment block 24 abuts against the brake caliper 4 first, compared to the first abutment block 23. The second abutment block 24 is equipped with a spring 26, which constantly drives the second abutment block 24 to slide away from the corresponding sliding seat 21. Thus, when clamping the brake caliper 4, the second abutment block 24 can firmly abut against the brake caliper 4 under the action of the spring 26. Even if the brake caliper 4 experiences slight displacement due to force during the test, the elastic force of the spring 26 ensures that the second abutment block 24 always maintains close contact with the brake caliper 4. Together with the first abutment block 23, they provide a stable and reliable clamping for the brake caliper 4, ensuring that the brake caliper 4 will not loosen or shift during the test, guaranteeing the accuracy and reliability of the test results.

[0035] Reference Figure 5 and Figure 6 By rotating the adjusting screw 25, one end of which is threaded onto the sliding seat 21, it moves along its length during rotation. The other end of the adjusting screw 25 is slidably connected to the second abutment block 24, and both ends of the spring 26 abut against the adjusting screw and the second abutment block 24 respectively. Therefore, the movement of the adjusting screw 25 changes the compression degree of the spring 26, thereby precisely adjusting the preload of the spring 26. Precisely adjusting the preload of the spring 26 makes the clamping force of the second abutment block 24 on the brake caliper 4 more uniform and stable. During the test, regardless of the direction and magnitude of the force applied to the brake caliper 4, the clamping device 2 can maintain a stable clamping of the brake caliper 4 through the elastic deformation of the spring 26 and the fixing effect of the adjusting screw 25, preventing the brake caliper 4 from shaking or shifting on the test bench, thereby improving the accuracy and reliability of the test results.

[0036] Reference Figure 4 and Figure 5 A force-applying rod 27 is coaxially and fixedly connected to the adjusting screw 25. The end of the force-applying rod 27 away from the adjusting screw 25 passes through a sliding seat 21 to the outside. The end of the force-applying rod 27 located to the outside is provided with a force-applying handle 28. The operator can hold the force-applying handle 28 to more precisely control the rotation amplitude of the adjusting screw 25, thereby accurately adjusting the preload of the spring 26, achieving fine adjustment of the clamping force of the brake caliper 4, and ensuring that the clamping effect meets different testing requirements.

[0037] Reference Figure 3 and Figure 4The first abutment block 23 is tapered from one end near the sliding seat 21 to the other end away from the sliding seat 21. The brake caliper 4 usually has a certain bevel or curvature. The tapered first abutment block 23 can better fit the shape of the brake caliper 4, improve the adaptability of clamping, and provide a good clamping effect for different models of brake calipers 4 or different parts of the same model of brake caliper 4, thus enhancing the versatility and flexibility of the test bench clamping device 2.

[0038] Reference Figure 3 and Figure 4 Each of the first abutment blocks 23 and the second abutment blocks 24 has a rubber pad 29 on the side that contacts the brake caliper 4. Rubber has a large coefficient of friction, and the presence of the rubber pad 29 can increase the friction between the first abutment blocks 23 and the brake caliper 4, making the brake caliper 4 more stable after clamping and less prone to slipping or displacement during testing, thereby ensuring the accuracy and reliability of the test. The rubber pad 29 has a certain degree of elasticity and deformation capacity, which can better adapt to the unevenness or shape difference of the surface of the brake caliper 4. Even if there are some minor bumps or irregularities on the surface of the brake caliper 4, the rubber pad 29 can achieve a tight fit through its own deformation, improving the stability and reliability of the clamping.

[0039] Reference Figure 1 and Figure 4 The driving component 22 consists of several hydraulic cylinders 221, each corresponding to a different sliding seat 21. The hydraulic cylinders 221 are fixedly connected to the main body 1 of the test bench, and one end of the output shaft of each hydraulic cylinder 221 is fixedly connected to its corresponding sliding seat 21. This design, where multiple hydraulic cylinders 221 correspond to multiple sliding seats 21, allows each sliding seat 21 to be independently controlled and adjusted. This enables flexible adjustment of the position and movement of each sliding seat 21 according to different testing requirements, accommodating various types and specifications of brake calipers 4 and improving the versatility and adaptability of the test bench. The hydraulic cylinders 221 provide stable and large thrust or pull force, ensuring that the sliding seats 21 can move smoothly on the main body 1 of the test bench, thereby driving the brake calipers 4 clamped on the sliding seats 21 to accurately reach the designated position, meeting the requirements for adjusting the position of the brake calipers 4 under different testing conditions.

[0040] Reference Figure 1 and Figure 2A protective railing 3 is fixedly connected to one side of the main body 1 of the test bench, and a transparent protective plate 31 is installed on the protective railing 3. The protective railing 3 can prevent personnel from accidentally approaching the test bench during operation, preventing injury from moving parts or flying objects. The transparent protective plate 31 not only has a blocking function, but also allows operators to observe the test process from a safe distance, avoiding approaching dangerous areas while observing the test; the transparent protective plate 31 allows operators to clearly see the situation inside the test bench, facilitating real-time monitoring of the test process, timely detection of abnormalities and taking corresponding measures, which helps to improve the accuracy and repeatability of the test.

[0041] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
