Description

Technical Field

[0001] This invention belongs to the field of drilling technology, and in particular relates to a brake caliper durability testing device. Background Technology

[0002] Brake calipers are a key component of a motor vehicle's braking system. Located near the wheels, they control the contact between the brake pads and the brake discs, creating friction to slow or stop the vehicle. Brake calipers convert hydraulic pressure into mechanical force to decelerate or stop the vehicle; they are a type of disc brake.

[0003] For brake caliper durability testing, the braking effect and lifespan of the brake caliper are obtained by simulating actual braking. The actual durability test uses a one-to-one testing method between the brake caliper and the simulated brake disc. As the test proceeds, the simulated brake disc generates a lot of heat due to prolonged friction. This heat causes the friction of the brake caliper to deviate from the actual friction force, which will cause the brake caliper durability test data to deviate from the actual data to a certain extent, resulting in inaccurate test results. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a brake caliper durability testing device, which can effectively solve the problems of the prior art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention is a brake caliper durability testing device, comprising a durability testing chamber and a brake caliper body installed at the front opening of the durability testing chamber; Also includes: The drive motherboard is placed inside the cavity of the durability testing chamber. A servo motor for driving the drive motherboard to rotate is provided on one side of the center of the drive motherboard. Active support plates are fixed in a ring array on the outer wall of the drive motherboard. The end of the active support plate is attached to the brake disc center roller through the docking motherboard. A simulated brake disc is fixed on the side of the brake disc center roller. The side roller insertion hole is located at the center of the brake disc center roller. On the horizontal side of the side roller insertion hole, there is a drive main column and a connecting sleeve connected to the drive main column. The bottom of the connecting sleeve is connected to a moving block through a connecting base plate. Inside the moving block, there is a positive and negative threaded rod that drives the moving block to move horizontally. On one side of the connecting sleeve, there is a rotating connector for driving the drive main column to rotate and a drive motor connected to the rotating connector.

[0006] Furthermore, a connecting top plate is fixed to the top of the connecting sleeve, a conveyor body is fixed to the top of the connecting top plate, a discharge front end is installed at the output end of the conveyor body, a convex slider is fixed to the bottom of the conveyor body, and a transverse groove is provided on the inner wall of the durability testing chamber to allow the convex slider to slide and embed.

[0007] Furthermore, the surface of the durability testing chamber is provided with two sets of feeding windows distributed on both sides of the brake caliper body, and the opening height of the feeding windows is higher than the feeding port of the conveyor body.

[0008] Furthermore, a connecting inner crossbar is rotatably fitted on the inner side of the connecting sleeve, and two sets of drive main columns are symmetrically distributed on both sides of the connecting inner crossbar. A supporting crossbar is fixed at the end of the rotating connector away from the drive motor, and a through hole is opened at the end of the supporting crossbar near the drive main column to allow the drive main column to slide through.

[0009] Furthermore, the surface of the brake disc center roller is provided with a side roller groove, the front end of the mating main board adopts an arc-shaped part that matches the curvature of the side roller groove, and the other side of the brake disc center roller is provided with a mating block that matches the arc-shaped part of the mating main board.

[0010] Furthermore, a drive-side support rod is fixed to the side of the connecting base plate, and a support pile is fixed to the inner wall of the durability testing chamber. An extension cross plate is installed at the front end of the support pile, and a cross plate waist hole is opened on the surface of the extension cross plate. A connecting insert plate that slides laterally along the groove of the cross plate waist hole is fixed to the front end of the drive-side support rod.

[0011] Furthermore, a front support block is fixed at the front end of the extension plate, a support plate slot is provided on the surface of the active support plate to allow the front support block to be inserted laterally, and a transverse groove is provided on the surface of the support rear pile to allow the extension plate to slide laterally.

[0012] Furthermore, a collection chamber is provided below the simulated brake disc on one side of the brake caliper body, and a collection connecting plate connected to the connecting base plate is fixed to the side wall of the collection chamber.

[0013] Furthermore, the bottom of the collecting arc chamber is connected to a guiding communication chamber, and the inner groove of the collecting arc chamber is connected to the cavity of the guiding communication chamber.

[0014] Furthermore, a recycling outer compartment is located in front of the durability testing compartment, below the openings of the two sets of guide connecting compartments. The top of the recycling outer compartment has a guide port located below the openings of the guide connecting compartments, and an inner recycling drawer is installed inside the recycling outer compartment.

[0015] The present invention has the following beneficial effects: This invention features a set of drive mainboards and multiple sets of active support plates arranged in a ring array outside the drive mainboards within the durability testing chamber. Simulated brake discs can be constrained at the front end of the docking mainboard via the docking mainboard at the end of the active support plates. Simultaneously, a servo motor can drive the drive mainboards to rotate, causing the simulated brake discs to move one by one towards the brake caliper body. After the previous set of simulated brake discs has undergone braking friction testing with the brake caliper body and generated significant heat, the next set of simulated brake discs can be rotated to enter the brake caliper body's braking position. The heated simulated brake discs then detach from the brake caliper body for heat dissipation. This method makes the brake durability test of the brake caliper body more realistic, minimizing inaccuracies in durability time data caused by uneven friction due to the heat generated by the simulated brake discs.

[0016] After the simulated brake disc reaches the clamping position of the brake caliper body, the main column is driven to approach by the forward and reverse threaded rods. This allows the driving force of the drive motor and rotating connector to be transmitted to the simulated brake disc. The simulated brake disc is detachable, and different materials can be used to replace it according to actual needs. Furthermore, by injecting materials such as mud and sand into the conveyor body, the durability test can be made closer to actual driving conditions, further improving the accuracy of the durability test data of the brake caliper body.

Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figure 1-9 As shown, the present invention is a brake caliper durability testing device, including a durability testing chamber 1 and a brake caliper body 5 installed at the front opening of the durability testing chamber 1. Two sets of brake caliper mounting plates 4 are fixed on the front opening surface of the durability testing chamber 1. The two sets of brake caliper mounting plates 4 and the brake caliper body 5 are provided with corresponding mounting screw holes, so that the brake caliper body 5 can be stably assembled at the opening of the durability testing chamber 1. An arc-shaped partition is provided at the opening of the durability testing chamber 1. Observation windows 2 can be installed on the upper and lower sides of the partition for real-time observation of the internal testing process. The observation windows 2 can be installed by a detachable connection method such as snap-fit, magnetic attraction, or bolts, which facilitates the assembly of the brake caliper body 5 after the lower observation window 2 is disassembled. The entire durability testing chamber 1 has space for inspection and maintenance. At the same time, inspection doors 3 of different shapes and sizes are set on both sides of the durability testing chamber 1. The inspection doors 3 are rotating and can be opened, making it easy for personnel to enter through the inspection doors 3 to perform maintenance work on the internal equipment.

[0024] like Figure 2 as well as Figure 3 As shown, the drive motherboard 6 is placed inside the cavity of the durability testing chamber 1. A servo motor 7 for driving the drive motherboard 6 to rotate is provided on one side of the center of the drive motherboard 6. The base of the servo motor 7 is fixed to the inner wall of the durability testing chamber 1. The other side of the drive motherboard 6 can be supported by a support shaft to maintain the stability of the position and rotation of the drive motherboard 6. At the same time, active support plates 8 are fixed in a ring array on the outer wall of the drive motherboard 6. A docking motherboard 9 is fixed at the end of the active support plate 8. The active support plates 8 and the active support plate 9 are distributed in a Y-shape. A simulated brake disc 10 is placed in the gap between the two sets of docking motherboards 9. A brake disc center roller 11 is fixed at the center of both ends of the simulated brake disc 10. A side roller groove 13 is opened on the surface of the brake disc center roller 11. The front end of the docking motherboard 9 adopts an arc-shaped part that matches the curvature of the side roller groove 13. A docking block 12 that matches the arc-shaped part of the docking motherboard 9 is provided on the other side of the brake disc center roller 11. In summary, when installing the simulated brake disc 10, first place the simulated brake disc 10 in the gap between the two sets of mating main plates 9. Then, attach the side roller groove 13 to the arc-shaped part at the front end of the mating main plate 9 to maintain the contact between the brake disc center roller 11 and the mating main plate 9. Then, attach the arc-shaped concave surface of the brake disc center roller 11 to the side roller groove 13. The surfaces of the mating block 12 and the mating main plate 9 are provided with corresponding screw holes. Connect the screws to the mating block 12 and the mating main plate 9 to clamp the mating main plate 9 and the mating block 12 outside the side roller groove 13. It is worth noting that when the mating block 12 and the mating main plate 9 are in the maximum connection position, there is still a certain gap between them and the side roller groove 13, so that the brake disc center roller 11 and the mating block 12 fixedly connected to the brake disc center roller 11 can rotate.

[0025] To enable the simulated brake disc 10 to rotate after reaching the position of the brake caliper body 5, the design is as follows: Figure 2 as well as Figure 5 As shown, a side roller insertion hole 19 is provided through the center of the brake disc center roller 11, and the side roller insertion hole 19 is multi-faceted. A drive main column 18 is provided on the coaxial side of the side roller insertion hole 19 at the detection position where the simulated brake disc 10 reaches the brake caliper body 5. The drive main column 18 is also multi-faceted. The entire drive main column 18 can move laterally. By inserting it into the side roller insertion hole 19, the rotation of the drive main column 18 can complete the rotation of the side roller insertion hole 19, thereby conducting a durability test of the brake caliper. The drive column 18 is designed in two sections, which are fixedly connected by a connecting inner crossbar 27. The drive column 18 is symmetrically distributed on both sides of the connecting inner crossbar 27, which has a smaller radius. A set of connecting sleeves 17 is rotatably fitted around the connecting inner crossbar 27, and the connecting sleeves 17 do not affect the normal operation of the drive column 18 or the normal rotation of the connecting inner crossbar 27. A supporting crossbar 16 is connected to the end of the drive column 18 on one side of the roller insertion hole 19. The surface of the supporting crossbar 16 has through holes that allow the drive column 18 to slide in and out. The support cylinder 16 supports the drive column 18. At the same time, a rotating connector 15 is fixedly connected to the rear end of the support cylinder 16. The other end of the rotating connector 15 is connected to a drive motor 14 for driving the rotating connector 15 to rotate. The base of the drive motor 14 is fixedly connected to the inner wall of the durability testing chamber 1. In actual operation, the drive motor 14 drives the rotating connector 15 to rotate, which in turn drives the support cylinder 16 and the drive column 18 that is slidably connected to the support cylinder 16 to rotate. After the drive column 18 extends into the side roller insertion hole 19, it can drive the simulated brake disc 10 to rotate.

[0026] To achieve the lateral reciprocating motion of the drive column 18, the design... Figure 2 , Figure 6 as well as Figure 7 As shown, a downwardly extending connecting base plate 20 is fixedly provided at the bottom of the connecting sleeve 17, and a moving block 21 is fixedly connected to the bottom of the connecting base plate 20. A positive and negative threaded rod 22 is connected to the bottom of the moving block 21, and a motor is provided at one end of the positive and negative threaded rod 22. Through the motor and the positive and negative threaded rod 22, the two sets of moving blocks 21 and the structure connected to the top of the moving blocks 21 can move synchronously. When the simulated brake disc 10 enters the detection position of the brake caliper body 5, the moving block 21 drives the drive main column 18 to insert. The drive motor 14 drives the drive main column 18 to rotate, which in turn causes the simulated brake disc 10 to rotate. The drive main columns 18 on both sides of the simulated brake disc 10 move inward and outward in sync. Conversely, before the servo motor 7 needs to drive the drive main board 6 to rotate, the drive motor 14 stops and the moving block 21 moves in the opposite direction so that the drive main column 18 can exit from the hole in the side roller insertion part 19. The entire positive and negative thread screw 22 and motor are installed on the inner wall of the durability testing chamber 1 and remain stable.

[0027] To further improve the stability of the active support plate 8, the design is as follows: Figure 8 As shown, a drive-side support rod 28 is fixed to the side wall of the connecting base plate 20, and the other end of the drive-side support rod 28 is fixedly connected to an extension horizontal plate 29. A support rear post 32 is connected to the end of the extension horizontal plate 29, so that the back of the support rear post 32 is fixed to the inner wall of the durability testing chamber 1. Simultaneously, a transverse groove is formed on the surface of the support rear post 32 to allow the extension horizontal plate 29 to move laterally within the transverse groove of the support rear post 32, with the support rear post 32 providing support for the extension horizontal plate 29. A connecting insert plate 31 is fixed to one end of the drive-side support rod 28, allowing the connecting insert plate 31 to be connected to the extension horizontal plate 29. Plate 31 is placed in the horizontal plate waist hole 30 opened on the surface of the extension horizontal plate 29. When the drive side support rod 28 moves, the horizontal plate waist hole 30 can be dragged to move towards the active support plate 8. The front end of the extension horizontal plate 29 is fixed with a support front stop 33 that is adapted to the support plate slot 34 opened on the surface of the active support plate 8, so that the support front stop 33 extends into the slot of the support plate slot 34. At the same time, the support front stop 33 is also wrapped around the active support plate 8. Therefore, the support front stop 33 is used to provide overall support for the active support plate 8, thereby improving the stability of the active support plate 8 in this horizontal position.

[0028] To make the entire durability test more in line with actual conditions, the design is as follows: Figure 4As shown, a connecting top plate 23 is fixedly provided on the top of the connecting sleeve 17, and a conveyor body 24 is fixedly provided on the top of the connecting top plate 23. A discharge front end 25 is installed at the output end of the conveyor body 24, and a convex slider part 26 is fixedly provided at the bottom of the conveyor body 24. A transverse groove is provided on the inner wall of the durability testing chamber 1 to allow the convex slider part 26 to slide and embed. Suitable mud and sand are put into the feeding port of the conveyor body 24, and the material is discharged from the discharge front end 25 to the surface of the simulated brake disc 10 by the screw drive inside the conveyor body 24, so that the simulated test is closer to reality, thereby improving the accuracy of the durability test of the brake caliper to a certain extent. To facilitate material feeding to the conveyor body 24, two sets of feeding windows 43 are provided on the surface of the durability testing chamber 1 and on both sides of the opening. By opening the cover of the feeding window 43, material can be fed into the feeding port of the conveyor body 24 from the feeding window 43. It is worth noting that the horizontal position of the two sets of feeding windows 43 needs to be higher than the feeding port of the conveyor body 24 for easier material feeding.

[0029] In order to collect as much of the sediment used above as possible, the design is as follows: Figure 5 As shown, a collection chamber 38 is provided below the simulated brake disc 10 located on one side of the brake caliper body 5, and a collection connecting plate 37 connected to the connecting base plate 20 is fixed on the side wall of the collection chamber 38. The bottom end of the collecting arc chamber 38 is connected to the guiding communication chamber 39. The inner groove of the collecting arc chamber 38 is connected to the cavity of the guiding communication chamber 39. After the two sets of collecting arc chambers 38 are pushed by the collecting connecting plate 37, their sides are attached together. The side height of the two sets of collecting arc chambers 38 near the end is lower, and the side height of the side away from the end is higher. After the two sets of collecting arc chambers 38 are attached together, they can catch the mud and sand falling from above. The inner wall of the collecting arc chamber 38 is arc-shaped, and the mud and sand can be more easily discharged from the guiding communication chamber 39 along the arc-shaped inner wall. The front of the durability testing chamber 1 is provided with a recycling outer chamber 40 located below the opening of the two sets of guiding communication chambers 39. The top of the recycling outer chamber 40 is provided with a guide port 41 located below the opening of the guiding communication chamber 39. The recycling outer chamber 40 is equipped with a recycling inner drawer 42. The mud and sand discharged from the guiding communication chamber 39 falls into the guide port 41 and is collected inside the recycling inner drawer 42. The mud and sand in the recycling inner drawer 42 can be taken out periodically for reuse.

[0030] A heat dissipation chamber 35 is set below the entire drive motherboard 6, and a cooling fan 36 is fixed on the side of the heat dissipation chamber 35. The outer wall of the heat dissipation chamber 35 is connected to the inner wall of the durability testing chamber 1. The cooling fan 36 blows air into the heat dissipation chamber 35. The top of the heat dissipation chamber 35 is open, which does not affect the rotation and entry and exit of the simulated brake disc 10. At the same time, the simulated brake disc 10 that has just completed the friction test is quickly cooled down in the heat dissipation chamber 35.
