Description

Technical Field

[0001] This application relates to the field of automotive component testing equipment technology, and in particular to an installation device for an automatic adjustment arm test bench for automotive brake clearance. Background Technology

[0002] The automatic brake clearance adjuster arm is a crucial component of the automotive braking system, and its performance directly impacts braking effectiveness and driving safety. Testing the automatic brake clearance adjuster arm allows for the timely detection of potential problems, ensuring its proper functioning in real-world applications and thus guaranteeing vehicle braking safety. Currently, automotive automatic brake clearance adjuster arm test benches can simulate various operating conditions and usage scenarios to perform performance tests on the adjuster arm. This helps optimize the design and manufacturing process of the adjuster arm, improving its reliability and stability. Simultaneously, it can also enhance the overall efficiency of the braking system, reducing wear and energy loss during braking.

[0003] In related technologies, traditional automotive brake clearance automatic adjustment arm test benches use a relatively simple method for installing and fixing the automatic brake clearance adjustment arm. This typically relies on simple clamps or fixing devices, fixed from a single direction. The fixing force is insufficient and the stability is poor. During testing, the adjustment arm is subjected to various external forces, such as the impact force generated during simulated braking. This simple fixing method easily leads to displacement or loosening of the adjustment arm, thus affecting the accuracy and reliability of the test data. Furthermore, the method of adjusting the angle after installing and fixing the automatic brake clearance adjustment arm is relatively simple and inflexible, mostly achieving only simple horizontal or limited angle tilt adjustments. This is insufficient to meet the diverse angle requirements of different automotive brake clearance adjustment arms under actual braking conditions. Due to differences in the braking system design of different vehicle models, the angle range involved in the operation of the brake clearance adjustment arm is wide. If the test bench cannot simulate these actual angles, it cannot comprehensively and accurately detect the performance of the adjustment arm under various operating conditions, leading to some potential problems going undetected.

[0004] Therefore, we propose an installation device for an automatic adjustment arm test bench for automotive brake clearance to solve the above problems. Utility Model Content

[0005] The purpose of this application is to provide an installation device for an automatic brake clearance adjustment arm test bench, which can reliably install and fix the automatic brake clearance adjustment arm on the support platform, prevent the automatic brake clearance adjustment arm from shifting or loosening during the test, and allow for multi-angle adjustment of the test angle position of the automatic brake clearance adjustment arm according to the test requirements.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution: an installation device for an automatic brake clearance adjustment arm test bench, comprising a test bench body for testing the automatic brake clearance adjustment arm and a bracket fixed on the top of the test bench body, an adjustment mechanism on the bracket, a support platform on the adjustment mechanism, the adjustment mechanism for adjusting the angle position of the support platform, the support platform for placing the automatic brake clearance adjustment arm, and an installation positioning mechanism on the support platform for clamping and fixing the automatic brake clearance adjustment arm on the support platform.

[0007] By adopting the above technical solution, the design of the adjustment mechanism enables the platform to flexibly adjust its angle position, which can meet the diverse angle requirements of different models of vehicle brake clearance automatic adjustment arm testing, ensuring the comprehensiveness and accuracy of the test. The installation and positioning mechanism can securely clamp and fix the vehicle brake clearance automatic adjustment arm on the platform, and the vehicle brake clearance automatic adjustment arm will not loosen or fall off during the test.

[0008] The further configuration of this application is as follows: the installation and positioning mechanism includes two limiting plates, multiple electric push rods and multiple clamping heads. The two limiting plates are fixedly installed on the top of the bearing platform and are symmetrically distributed. The multiple electric push rods are fixedly installed on the side of the two limiting plates that are far apart from each other and are evenly distributed. The multiple clamping heads are respectively fixedly installed on the output shaft end of the corresponding electric push rod.

[0009] By adopting the above technical solution, multiple electric push rods on the two limit plates, together with multiple clamping heads, can limit and clamp the automatic adjustment arm of the vehicle brake clearance from both sides.

[0010] The further configuration of this application is as follows: the installation positioning mechanism also includes two fixed beams, two electric push rods, and two clamping heads. The two fixed beams are respectively fixedly installed on the top of the corresponding limiting plates, and the two electric push rods are respectively fixedly installed on the ends of the two fixed beams that are close to each other. The two electric push rods are both inclined, and the two clamping heads are respectively fixedly installed on the output shaft ends of the corresponding electric push rods.

[0011] By adopting the above technical solution, the electric push rods on the two fixed beams, together with the two clamping heads, can further press and fix the automatic adjustment arm of the vehicle brake clearance from above.

[0012] A further feature of this application is that anti-slip rubber pads are fixedly installed on one side of clamping head one and one side of clamping head two.

[0013] By adopting the above technical solution, the design of the anti-slip rubber pad increases friction, preventing the automatic brake clearance adjustment arm of the vehicle from shifting during the test, ensuring the stability and reliability of the test, and effectively protecting the clamping part of the automatic brake clearance adjustment arm of the vehicle, avoiding damage to its surface.

[0014] The further configuration of this application is as follows: the adjustment mechanism includes a first bearing seat, a horizontal shaft, an outer cover, a secondary gear, a motor, a main gear, a U-shaped beam, a second bearing seat, a rotating shaft, and a locking assembly. The first bearing seat is fixedly installed on one side of the bracket, the horizontal shaft is rotatably installed on one side of the first bearing seat, the outer cover is fixedly fitted onto the horizontal shaft, the left side of the outer cover has an open structure, the secondary gear is fixedly fitted onto the horizontal shaft, the motor is fixedly installed on one side of the bracket, the main gear is fixedly installed on the output shaft end of the motor, the main gear meshes with the secondary gear, one end of the U-shaped beam is fixedly installed on the inner wall of the outer cover, the other end of the U-shaped beam is located outside the outer cover and has a groove, the second bearing seat is fixedly installed in the groove, the rotating shaft is rotatably installed on the second bearing seat, the support platform is fixedly installed on the top of the rotating shaft, and the bottom surface of the support platform is in contact with the end of the U-shaped beam located outside the outer cover.

[0015] By adopting the above technical solution, the motor drives the main gear to rotate. The meshing transmission between the main gear and the auxiliary gear can drive the horizontal shaft to rotate, thereby causing the outer cover and the U-shaped beam fixed on the outer cover to rotate. The support platform is connected to the U-shaped beam through the rotating shaft, thus achieving the purpose of multi-angle adjustment.

[0016] A further feature of this application is that the secondary gear, the motor, and the main gear are all located inside the outer casing.

[0017] By adopting the above technical solution, the outer cover plays a protective role, which can greatly reduce the entry of dust, debris and other contaminants, avoid affecting the accuracy of gear transmission and normal use, and extend the service life of the equipment.

[0018] A further feature of this application is that the bottom surface of the support platform and the end of the U-shaped beam located outside the outer cover are both smooth flat surfaces.

[0019] By adopting the above technical solution, the friction force during the rotation of the support platform is reduced, making the angle adjustment of the support platform smoother.

[0020] The further configuration of this application is as follows: the locking assembly includes a sanding disc, two electric actuators, and two sanding beams. The sanding disc is fixedly mounted on the U-shaped beam and located below the support platform. The two electric actuators are both fixedly installed at the bottom of the support platform and are symmetrically distributed on both sides of the sanding disc. The two sanding beams are respectively fixedly installed at the output shaft ends of the corresponding electric actuators. Both sanding beams abut against the bottom surface of the sanding disc.

[0021] By adopting the above technical solution, when it is necessary to lock the angle of the bearing platform, the force generated by the two electric actuators pushing the corresponding abrasive beam upward and contacting the bottom surface of the abrasive disc can firmly lock the bearing platform, avoiding changes in the angle of the bearing platform due to vibration and other factors during the test, thus improving the accuracy of the test.

[0022] A further feature of this application is that the top surfaces of the two frosted beams and the bottom surface of the frosted disc are both frosted.

[0023] By adopting the above technical solution, greater friction can be generated at the contact points between the frosted beam and the frosted disc, thereby enhancing the locking effect on the support platform.

[0024] This application includes at least one of the following beneficial technical effects:

[0025] 1. This application uses an installation positioning mechanism to securely install and fix the automatic brake clearance adjustment arm of the vehicle on the support platform. During the test, it can prevent the automatic brake clearance adjustment arm of the vehicle from shifting or loosening, thus ensuring the stability and reliability of the test process.

[0026] 2. This application, through its adjustment mechanism, can adjust the angle position of the automatic brake clearance adjustment arm test at multiple angles according to the test requirements, thus meeting the diverse angle requirements of different models of vehicles during the test of the automatic brake clearance adjustment arm.

[0033] The technical solution of this application will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0034] See Figures 1-5 This application provides an installation device for an automatic brake clearance adjustment arm test bench for automobiles, including a test bench body 1 for testing the automatic brake clearance adjustment arm and a bracket 2 fixed to the top of the test bench body 1. The bracket 2 can be fixed to the top of the test bench body 1 with screws, thus facilitating the assembly and disassembly of the bracket 2. The bracket 2 is provided with an adjustment mechanism, and a support platform 3 is provided on the adjustment mechanism. The adjustment mechanism is used to adjust the angle position of the support platform 3. The support platform 3 is used to place the automatic brake clearance adjustment arm for automobiles. The support platform 3 is provided with an installation positioning mechanism, which is used to clamp and fix the automatic brake clearance adjustment arm for automobiles onto the support platform 3. The installation positioning mechanism includes two limiting plates 4, multiple electric push rods 5, multiple clamping heads 6, two fixing beams 7, two electric push rods 8, and two clamping heads 9. The two limiting plates 4 are fixedly installed on the top of the support platform 3 and are symmetrically distributed. The multiple electric push rods 5 are fixed... Installed on the side of the two limiting plates 4 that are far apart from each other and evenly distributed, multiple clamping heads 6 are fixedly installed on the output shaft ends of the corresponding electric push rods 5. By utilizing the telescopic feature of the multiple electric push rods 5, the linear movement of the corresponding clamping heads 6 can be controlled separately. Thus, under the synergistic action of the multiple clamping heads 6, the automatic adjustment arm of the vehicle brake clearance can be initially limited and clamped from both sides. Two fixed beams 7 are fixedly installed on the top of the corresponding limiting plates 4. Two electric push rods 8 are fixedly installed on the ends of the two fixed beams 7 that are close to each other. Both electric push rods 8 are inclined. Two clamping heads 9 are fixedly installed on the output shaft ends of the corresponding electric push rods 8. By utilizing the telescopic feature of the two electric push rods 8, the linear movement of the corresponding clamping heads 9 can be controlled separately. Thus, under the synergistic action of the two clamping heads 9, the automatic adjustment arm of the vehicle brake clearance can be further pressed and fixed on the support platform 3 from above.

[0035] In this embodiment, anti-slip rubber pads 10 are fixedly installed on one side of clamping head 6 and one side of clamping head 9. By using anti-slip rubber pads 10, displacement of the automatic adjustment arm of the vehicle brake clearance can be prevented during the test, ensuring the stability and reliability of the test. In addition, it plays an effective role in protecting the clamping part of the automatic adjustment arm of the vehicle brake clearance and avoiding damage to its surface.

[0036] In this embodiment, the adjustment mechanism includes a first shaft seat 11, a horizontal shaft 12, an outer cover 13, a secondary gear 14, a motor 15, a main gear 16, a U-shaped beam 17, a second shaft seat 18, a rotating shaft 19, and a locking assembly. The first shaft seat 11 is fixedly installed on one side of the bracket 2, the horizontal shaft 12 is rotatably installed on one side of the first shaft seat 11, the outer cover 13 is fixedly fitted onto the horizontal shaft 12, and the left side of the outer cover 13 is open. The secondary gear 14 is fixedly fitted onto the horizontal shaft 12, the motor 15 is fixedly installed on one side of the bracket 2, and the main gear 16 is fixedly installed on the output shaft end of the motor 15. The main gear 16 meshes with the secondary gear 14. The secondary gear 14, the motor 15, and the main gear 16 are all located inside the outer cover 13. One end of the U-shaped beam 17 is fixedly installed on the inner wall of the outer cover 13, and the other end of the U-shaped beam 17 is located outside the outer cover 13 and has a groove. The second shaft seat 18 is fixedly installed in the groove, and the rotating shaft... The shaft 19 is rotatably mounted on the bearing seat 18, and the bearing platform 3 is fixedly mounted on the top of the shaft 19. The bottom surface of the bearing platform 3 is in contact with the end of the U-shaped beam 17 located outside the outer cover 13. Both the bottom surface of the bearing platform 3 and the end of the U-shaped beam 17 located outside the outer cover 13 are smooth flat surfaces. The main gear 16 is driven to rotate by the motor 15. Under the meshing transmission action of the main gear 16 and the auxiliary gear 14, the horizontal shaft 12 can be driven to rotate, thereby causing the outer cover 13 and the U-shaped beam 17 fixed on the outer cover 13 to rotate. The bearing platform 3 follows the U-shaped beam 17 to rotate around the horizontal shaft 12. The bearing platform 3 is connected to the U-shaped beam 17 through the bearing seat 18 and the shaft 19, so that the bearing platform 3 can rotate around the shaft 19, thereby achieving the purpose of multi-angle adjustment. For example, when simulating the angle under different actual braking conditions of vehicles, it can be accurately adjusted to the corresponding position.

[0037] In this embodiment, the locking assembly includes a frosted disc 20, two electric actuators 21, and two frosted beams 22. The frosted disc 20 is fixedly mounted on the U-shaped beam 17 and located below the support platform 3. The two electric actuators 21 are fixedly installed at the bottom of the support platform 3 and are symmetrically distributed on both sides of the frosted disc 20. The two frosted beams 22 are respectively fixedly installed at the output shaft ends of the corresponding electric actuators 21. Both frosted beams 22 are in contact with the bottom surface of the frosted disc 20. By utilizing the telescopic feature of the two electric actuators 21, the linear movement of the corresponding frosted beams 22 can be controlled. When both frosted beams 22 are in tight contact with the bottom surface of the frosted disc 20, the support platform 3 can be firmly locked. When both frosted beams 22 are not in contact with the bottom surface of the frosted disc 20, the locking of the support platform 3 can be released.

[0038] In this embodiment, the top surfaces of the two frosted beams 22 and the bottom surfaces of the frosted disc 20 are both frosted, which can generate greater friction at the contact points between the frosted beams 22 and the frosted disc 20, thereby enhancing the locking effect on the support platform 3.

[0039] In this embodiment, it should be noted that the electric actuator 1 5, electric actuator 2 8, electric actuator 3 21 and motor 15 can all be purchased on the market. The motor 15 is a reversible motor, and its wiring connection method and control method are mature technologies in the field and have been fully disclosed. Therefore, they will not be described again in this article.

[0040] With the above structure, the installation device of the automatic brake clearance adjustment arm test bench provided in this application, when in use, places the automatic brake clearance adjustment arm between the two limiting plates 4 on the support platform 3, controls the extension of multiple electric push rods 5, so that the output shafts of the multiple electric push rods 5 drive the corresponding clamping heads 6 to move until the anti-slip rubber pads 10 on the multiple clamping heads 6 are in tight contact with the side of the automatic brake clearance adjustment arm, and the automatic brake clearance adjustment arm can be clamped and fixed from both sides. Then, controls the extension of two electric push rods 8, so that the output shafts of the two electric push rods 8 drive the corresponding clamping heads 9 to tilt downward until the anti-slip rubber pads 10 on the two clamping heads 9 are in tight contact with the upper surface of the automatic brake clearance adjustment arm, and the automatic brake clearance adjustment arm can be pressed and fixed on the support platform 3 from above, thus completing the stable and reliable installation and fixing of the automatic brake clearance adjustment arm, effectively preventing the automatic brake clearance adjustment arm from shifting or loosening during the test, and ensuring the stability and reliability of the test process;

[0041] After the automatic brake clearance adjusting arm is installed and fixed, during testing, the motor 15 is controlled to rotate forward or backward. The output shaft of the motor 15 drives the main gear 16 to rotate, which in turn drives the secondary gear 14 and the horizontal shaft 12 to rotate. When the horizontal shaft 12 rotates, the outer cover 13 also rotates around the axis of the horizontal shaft 12. The rotation of the outer cover 13 drives the U-shaped beam 17 to rotate as well, so that the bearing platform 3 and the automatic brake clearance adjusting arm installed and fixed on it can rotate around the horizontal shaft 12 as the center, thereby adjusting and changing the angle position of the automatic brake clearance adjusting arm. By controlling the extension of the two electric push rods 21, the two abrasive beams 22 are prevented from contacting the abrasive disc 20, thus releasing the bearing platform. After locking and fixing the platform 3, the platform 3 can be rotated, causing the platform 3 and the automatically adjusting arm for the vehicle brake clearance that is fixed on it to rotate around the pivot 19. This allows for further adjustment of the angle position of the automatically adjusting arm for the vehicle brake clearance. Once the angle of the automatically adjusting arm for the vehicle brake clearance is adjusted, the two electric push rods 21 are controlled to retract and reset, causing the two abrasive beams 22 to come into tight contact with the abrasive disc 20. This restricts the rotation of the platform 3 around the pivot 19, allowing for multi-angle adjustment of the angle position of the automatically adjusting arm for the vehicle brake clearance according to testing requirements. This can meet the diverse angle requirements for testing the automatically adjusting arm for the vehicle brake clearance of different models.
