Description

Technical Field

[0001] This application relates to the field of vehicle control braking system equipment, and in particular to a brake pad braking detection device. Background Technology

[0002] Brake pads, also known as brake discs, are components installed in a car's braking system for braking. A car's wheels are mounted on axles, and brake discs are installed on these axles. The braking system controls the contact between the brake pads and the brake discs, stopping the axle's rotation and thus achieving the effect of braking the vehicle.

[0003] After brake pads are manufactured, they need to undergo performance testing. Existing brake pad testing equipment includes a base plate, a telescopic component, a mounting base, and multiple sensors. The telescopic component can be a pneumatic or hydraulic cylinder. One end of the telescopic component is connected to the base plate, and the other end is connected to the mounting base. The mounting base has a groove for mounting the brake pad on the side closest to the base plate. Multiple sensors are mounted on the mounting base. The telescopic component moves the mounting base, thereby allowing the brake pad to move. By placing the rotating brake disc between the mounting base and the base plate, the brake pad can contact the brake disc. The sensors can detect the coefficient of friction of the brake pad under different temperatures and pressures, thereby measuring the data of the brake pad during braking.

[0004] The aforementioned technical solutions have the following drawbacks: During brake pad testing, it is necessary to control the brake pads to contact the rotating brake disc and the stationary brake disc separately, so as to measure the brake pad performance when the vehicle is braking and when the handbrake is pulled in the stationary vehicle. The brake pad testing process requires the brake pads to be installed on different testing machines, which results in low testing efficiency. Summary of the Invention

[0005] In order to enable the testing of brake pad performance under different operating conditions in the same device, this application provides a brake pad braking testing device.

[0006] The brake pad braking detection device provided in this application adopts the following technical solution:

[0007] A brake pad testing device includes a frame, a brake pad simulator, and a disc. The disc is rotatably connected to the frame, and the axial direction of the disc is horizontal. The brake pad simulator is slidably connected to the frame and is used to move to the upper side of the disc to test the brake pads.

[0008] By adopting the above technical solution, the brake pad simulator is slidably connected to the frame, allowing it to slide horizontally along a straight line. The sliding direction of the brake pad simulator is parallel to the disc, and the brake pad simulator can slide above the rotating disc, so that the brake pads installed in the brake pad simulator can abut against the rotating disc, achieving the effect of testing the performance of the brake pads when the vehicle is braking. After the test is completed, the brake pad simulator slides to a position away from the disc. At this time, the brake pad simulator can clamp non-rotating parts, thereby testing the effect of clamping brake pads in a stationary state. It is possible to test the performance of brake pads in different working states in the same device, and the testing efficiency of brake pads in two states is higher.

[0009] Optionally, the brake pad simulator includes a base plate, a mounting base, multiple sensors, and a telescopic component. The base plate is slidably connected to the frame, one end of the telescopic component is fixed to the base plate, and the other end is connected to the mounting base. The length direction of the telescopic component is parallel to the axial direction of the disc, and the sensors are mounted on the mounting base.

[0010] By adopting the above technical solution, by setting a telescopic component on the substrate, the telescopic component can control the gap between the substrate and the mounting base, thereby enabling the brake pads mounted on the mounting base to abut against the disc, thus simulating the action of wheel braking.

[0011] Optionally, an insert plate is mounted on the substrate, and a positioning component is mounted on the frame. The positioning component has an insertion hole, and the insert plate is used to insert into the insertion hole. The positioning component has multiple positioning holes, and the insert plate has multiple through holes. A pin is detachably connected to the positioning hole.

[0012] By adopting the above technical solution, by setting an insert plate on the base plate, the insert plate can be inserted into the positioning component when the brake pad simulator clamps the rotating disk. By inserting a pin into the positioning component, the pin passes through the positioning component and the insert plate, thereby keeping the brake pad simulator fixed on the frame. This reduces the probability of the brake pad simulator moving during testing and improves the accuracy of the test data.

[0013] Optionally, the brake pad simulator may be detachably connected to a wheel simulation card, which is inserted between the mounting base and the base plate.

[0014] By adopting the above technical solution and setting wheel simulation cards in the brake pad simulator, users can insert wheel simulation cards made of different materials into the brake pad simulator, thereby simulating more complex working conditions, detecting more diverse data, and achieving the effect of testing brake pad performance.

[0015] Optionally, the wheel simulation card includes a card plate and a handle, with the handle fixed to one side wall of the card plate.

[0016] By adopting the above technical solution and setting a handle on the card plate, it is convenient for users to insert and remove the wheel simulation card.

[0017] Optionally, a limiting block is fixed on the card plate, and a guide block is fixed at the bottom of the substrate. The guide block is inclined, and the limiting block is used to abut against the guide block.

[0018] By adopting the above technical solution, by setting a limiting block on the card plate and a guide block on the base plate, when the user inserts the card plate into the brake pad simulator, the limiting block and the guide block abut against each other, so that the card plate can be inserted into the brake pad simulator at an angle upward. The limiting block is stuck on one side of the base plate, which plays a positioning role, so that the card plate can be moved to a predetermined position between the brake pad and the base plate.

[0019] Optionally, a card strip is fixed on the card plate, the card strip is perpendicular to the card plate, and the card strip is used to snap onto the substrate.

[0020] By adopting the above technical solution, and by setting a locking strip on the card plate, when the card plate is inserted into the brake pad simulator, the locking strip can be locked on one side of the base plate, thereby allowing the card plate to move to a predetermined position for easy installation.

[0021] Optionally, the card plate has an inclined surface on the side away from the handle, and a hollow groove is formed on the card plate.

[0022] By adopting the above technical solution, by opening a bevel on the card plate, the beveled side of the card plate can be quickly inserted into the brake pad simulator. By opening a hollow groove on the card plate, the weight of the card plate can be further reduced, making it easier to move the card plate.

[0023] In summary, the beneficial technical effects of this application are as follows:

[0024] 1. By sliding the brake pad simulator on the frame, the brake pad simulator can slide horizontally in a straight line. The sliding direction of the brake pad simulator is parallel to the disc. The brake pad simulator can slide above the rotating disc, so that the brake pad installed in the brake pad simulator can abut against the rotating disc, achieving the effect of testing the performance of the brake pad when the vehicle is braking. After the test is completed, the brake pad simulator slides to a position away from the disc. At this time, the brake pad simulator can clamp the non-rotating parts, thereby testing the effect of clamping the brake pad in a stationary state. It can test the performance of the brake pad in different working states in the same device, and the testing efficiency of the two states of the brake pad is higher.

[0025] 2. By setting wheel simulation cards in the brake pad simulator, users can insert wheel simulation cards made of different materials into the brake pad simulator to simulate more complex working conditions, detect more diverse data, and achieve the effect of testing brake pad performance.

[0026] 3. By adopting the above technical solution, by opening a sloping surface on the card plate, the side of the card plate with the sloping surface can be quickly inserted into the brake pad simulator. By opening a hollow groove on the card plate, the weight of the card plate can be further reduced, making it easier to move the card plate. Attached Figure Description

[0033] The present application will be further described in detail below with reference to the accompanying drawings.

[0034] This application discloses a brake pad braking detection device, referring to... Figure 1 and Figure 2 The system includes a frame 1, a brake pad simulator 2, and a disc 3. The disc 3 is rotatably connected to the frame 1, and the disc 3 and the frame 1 form a horizontal axis of rotation. The brake pad simulator 2 is slidably connected to the frame 1 and is used to mount the brake pad to be tested. The brake pad simulator 2 can slide to the upper side of the disc 3, allowing the brake pad to be tested to move to one side of the disc 3. At this time, the brake pad simulator 2 drives the brake pad to abut against the rotating disc 3, thereby simulating the brake pad usage scenario. The brake pad simulator 2 detects the braking performance data of the brake pad.

[0035] When brake pads are installed in a car, a brake disc is mounted on the drive shaft. During normal driving, there is a gap of approximately 0.1-0.3 mm between the brake pads and the brake disc, minimizing the chance of debris entering the friction surfaces. When the car brakes, the brake pads and brake disc are in close contact, generating frictional heat on the brake pads. When the car stops and the driver engages the handbrake, the brake pads contact the brake disc, making it difficult for the car to roll and improving safety.

[0036] Reference Figure 1 The brake pad simulator 2 is detachably connected to a wheel simulation card 4. When the brake pad simulator 2 slides to the side away from the disc 3, the user inserts the wheel simulation card 4 into the brake pad simulator 2 so that the brake pads can squeeze the wheel simulation card 4. At this time, the brake pad simulator 2 detects the performance data of the brake pads when the car stops and the handbrake is pulled.

[0037] Reference Figure 3 A guide rail 11 is mounted on the frame 1, horizontally positioned on the top surface of the frame 1 and located on one side of the disc 3. The brake pad simulator 2 includes a base plate 21, a mounting base 22, multiple sensors 23, and a telescopic component 24. The base plate 21 is slidably connected to the guide rail 11 and is parallel to the disc 3. The mounting base 22 is fixed to the base plate 21, and the sensors 23 are mounted on the mounting base 22. The telescopic component 24 can be a hydraulic cylinder or a pneumatic cylinder. One end of the telescopic component 24 is fixed to the mounting base 22, and the other end is fixed to the frame 1. The telescopic component 24 is perpendicular to the base plate 21. There is a gap between the mounting base 22 and the base plate 21. When the base plate 21 slides onto the disc 3, the disc 3 is located between the mounting base 22 and the base plate 21. When the user mounts the brake pads onto the mounting base 22, the brake pads protrude from the surface of the mounting base 22. By controlling the telescopic component 24 to extend or retract, the user can move the brake pads along the axis of the disc 3, thereby allowing the brake pads to abut against the rotating disc 3. When the brake pads come into contact with the disc 3, they can be used to simulate the working state of the brake pads. The sensor 23 can detect data such as the brake pads' engagement gap, working gap, and slow release time.

[0038] Reference Figure 3A positioning component 12 is fixed to the top of the frame 1. The positioning component 12 has a slot and is fixed to one end of the guide rail 11. An insert plate 211 is fixed to the base plate 21. When the base plate 21 slides to a position where the brake pad can contact the disc 3, the insert plate 211 is inserted into the positioning component 12. The positioning component 12 has multiple vertically oriented positioning holes 121. The insert plate 211 has multiple through holes, the positions and sizes of which correspond one-to-one with the positioning holes 121. A pin 122 is detachably connected to the positioning component 12. One pin 122 is inserted into each positioning hole 121. The insert plate 211 can slide and be inserted into the positioning component 12. The pin 122, by inserting into the positioning component 12 and the insert plate 211, serves to fix the brake pad simulator 2. When the brake pad abuts against the disc 3, the brake pad simulator 2 is fixed on the frame 1 and maintains a stable position.

[0039] Reference Figure 4 and Figure 5 The wheel simulation card 4 includes a card plate 41 and a handle 42. The card plate 41 is used to insert between the brake pad and the base plate 21, and the handle 42 is fixed to one side of the card plate 41. When the user slides the brake pad simulator 2 to the edge of the frame 1, by inserting the card plate 41 into the brake pad simulator 2, the brake pad can contact and squeeze the card plate 41, thereby enabling the sensor 23 to detect the performance data of the brake pad, such as strength, stiffness, and deformation.

[0040] Reference Figure 4 and Figure 5 The card plate 41 has a hollowed-out groove 411, which is used to reduce the weight of the card plate 41. The card plate 41 has a bevel 412 on the side away from the handle 42, which makes it easier for the user to insert the card plate 41 into the brake pad simulator 2.

[0041] Reference Figure 4 and Figure 5 A limiting block 43 is fixed to one side of the clamping plate 41, and the limiting block 43 is used to abut against the side surface of the base plate 21. A guide block 212 is fixed on the base plate 21, and the guide block 212 is inclined upward. When the clamping plate 41 is inserted into the brake pad simulator 2, the limiting block 43 abuts against the guide block 212, so that the clamping plate 41 is inserted into the brake pad simulator 2 at an inclined upward, thereby making the brake pad installed in the brake pad simulator 2 tangential to the disc 3, so that the contact surface between the brake pad and the disc 3 is larger. A pad 213 is installed on the base plate 21, and the pad 213 is fixed on the upper side of the guide block 212. When the clamping plate 41 is inserted into the brake pad simulator 2, the pad 213 and the brake pad are respectively set on both sides of the clamping plate 41. When the brake pad is pressed on the clamping plate 41, the pad 213 provides support for the clamping plate 41.

[0042] Reference Figure 4 and Figure 5A locking strip 44 is fixed on the locking plate 41. The locking strip 44 is set perpendicular to the locking plate 41 and is located on the side of the locking plate 41 that is connected to the handle 42. When the locking plate 41 is inserted into the brake pad simulator 2, the locking strip 44 is locked onto the side wall of the base plate 21. The locking strip 44 has a positioning effect, making it convenient for the user to install the wheel simulation card 4 into the brake pad simulator 2.

[0043] The implementation principle of this application embodiment is as follows: by sliding the brake pad simulator 2 on the frame 1, the brake pad simulator 2 can slide to the disc 3. The disc 3 rotates to simulate the car brake disc. By making the brake pads contact the disc 3, the sensor 23 on the mounting base 22 can detect the data of braking such as the temperature rise and heat dissipation of the brake pads. By sliding the brake pad simulator 2 to a position away from the disc 3, the wheel simulation card 4 is inserted into the brake pad simulator 2, so that the brake pads can press on the wheel simulation card 4, thereby detecting the working performance of the brake pads when the car stops and the handbrake is pulled.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
