Description

Technical Field

[0001] The present invention relates to the technical field of testing equipment, in particular to a brake pad performance testing equipment. Background Art

[0002] Brake pads, also called brake pads, are the most critical safety parts in the car's braking system. Brake pads are generally composed of steel plates, adhesive insulation layers and friction blocks. The steel plates must be painted to prevent rust. The friction blocks are composed of friction materials and adhesives. When braking, they are squeezed on the brake disc or brake drum to generate friction, thereby achieving the purpose of slowing down and braking the vehicle.

[0003] Due to friction, the friction blocks will gradually wear out. Generally speaking, the lower the cost of the brake pads, the faster they wear out. Therefore, before the newly designed brake pads are officially put into production, it is necessary to conduct friction loss tests on the brake pad test samples to detect whether their wear resistance performance meets the standards. The traditional testing method is to use a motor to provide a rotation speed for the brake disc, use a speed sensor to simulate the vehicle speed, and then use a hydraulic cylinder to drive the brake pad to squeeze the brake disc to generate friction. Then use a timer to time the time the brake disc stops, so that the performance of the brake pad can be measured.

[0004] When the motor stops supplying power, even if its internal rotating parts will stop, the friction of the internal mechanism will cause the rotating shaft to still feel resistance after the motor loses power. This resistance is called "static friction". The existence of resistance will affect the rotation speed of the brake disc, and then affect the detection of the brake pad, resulting in inaccurate detection data. Summary of the invention

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Example 1: Please refer to Figures 1 to 4The present invention provides a technical solution: a brake pad performance testing device, comprising a testing platform 1 and a fixed plate 11, wherein the fixed plate 11 is fixedly mounted on the upper surface of the testing platform 1, a brake simulation component is arranged on the fixed plate 11, and the brake simulation component comprises a two-way hydraulic cylinder 2, wherein the two-way hydraulic cylinder 2 is fixedly mounted inside the fixed plate 11, a power frame 21 is fixedly mounted on the output shaft of the two-way hydraulic cylinder 2, a heat conducting plate 22 is fixedly mounted on one end of the power frame 21 away from the two-way hydraulic cylinder 2, heat conducting columns 23 are fixedly mounted on both sides of the surface of the heat conducting plate 22, a brake pad 24 is fixedly mounted on one end of the heat conducting column 23 away from the heat conducting plate 22, a testing piece 25 is movably mounted on the outer surface of the heat conducting column 23, a fixing frame 26 is fixedly mounted on the top of the testing piece 25, and one end of the fixing frame 26 away from the testing piece 25 is fixedly connected to the top of the fixed plate 11;

[0033] A mounting base 27 is fixedly mounted on the upper surface of the testing platform 1, a rotating shaft 28 is movably mounted inside the mounting base 27, a brake disc 29 is fixedly sleeved in the middle of the outer surface of the rotating shaft 28, a hydraulic rod 210 is fixedly mounted on one side of the mounting base 27, a driving plate 211 is fixedly mounted on the output shaft of the hydraulic rod 210, driving arms 212 are movably mounted on both sides of the driving plate 211, a mounting plate 213 is movably mounted on one end of the driving arm 212 away from the driving plate 211, and a slider 214 is fixedly mounted on the top of the mounting plate 213;

[0034] A servo motor 215 is fixedly mounted on the surface of the slider 214, a driving disk 216 is fixedly mounted on the output shaft of the servo motor 215, a connecting rod 217 is movably mounted on the edge of the surface of the driving disk 216, a rubber sleeve 218 is fixedly sleeved on the outer surface of the connecting rod 217 away from the driving disk 216, a driven disk 219 is fixedly mounted on the end of the rotating shaft 28 close to the hydraulic rod 210, a docking sleeve 220 is fixedly mounted on the edge of the surface of the driven disk 219, and the rubber sleeve 218 is movably mounted inside the docking sleeve 220;

[0035] A mounting frame 222 is fixedly mounted on the upper surface of the detection platform 1, and the mounting frame 222 is movably connected to the middle position of the driving arm 212;

[0036] The shape of the slider 214 is T-shaped, and the slider 214 is movably installed inside the testing platform 1. The inside of the testing platform 1 is provided with a slide groove 223 adapted to the slider 214;

[0037] The outer surface of the heat-conducting column 23 is sleeved with a first return spring 221, one end of the first return spring 221 is fixedly connected to the surface of the heat-conducting plate 22, and one end of the first return spring 221 away from the heat-conducting plate 22 is fixedly connected to the surface of the detection member 25;

[0038] A vehicle condition simulation component is provided on the heat conducting plate 22 , and the vehicle condition simulation component is used to improve the test accuracy.

[0039] During the test, the motor provides the brake disc with a rotation speed. When the motor stops supplying power, even if the rotating parts inside it stop, the friction of the internal mechanism will cause the motor to still feel resistance after losing power. The existence of resistance will reduce the rotation speed of the shaft 28, causing the brake disc 29 to stop rotating earlier, resulting in inaccurate test data during the braking time test.

[0040] Specifically, during the test, the servo motor 215 is started to drive the driving disk 216 to rotate, so that the driving disk 216 drives the connecting rod 217, and the connecting rod 217 can drive the driven disk 219, so that the driven disk 219 rotates, and the driven disk 219 can drive the rotating shaft 28 to rotate, so that the brake disk 29 rotates, and the speed of the servo motor 215 is controlled by the speed sensor. When the speed of the servo motor 215 reaches the test speed, it is necessary to stop the power supply to the servo motor 215;

[0041] Then, the hydraulic rod 210 is started to drive the driving plate 211 to descend, so that the driving plate 211 presses down one end of the driving arm 212, so that the other end of the driving arm 212 moves outward, and then the mounting plate 213 is driven to move the mounting plate 213. At this time, the rubber sleeve 218 is separated from the docking sleeve 220, and the rotation of the rotating shaft 28 is no longer affected by the internal resistance of the servo motor 215.

[0042] Then, the bidirectional hydraulic cylinder 2 is started to drive the power frame 21, so that the power frame 21 drives the heat conducting plate 22 to move, and the heat conducting plate 22 drives the heat conducting column 23, so that the heat conducting column 23 drives the brake pad 24 to brake the brake disc 29, and the timing is performed during braking until the brake disc 29 stops rotating, so that the braking effect of the brake pad 24 can be measured without being affected by the internal resistance of the servo motor 215, which can make the test data more accurate;

[0043] It should be noted that before testing, check whether the rubber sleeve 218 is installed. During the separation process of the connecting rod 217 and the docking sleeve 220, the rotation speed between the connecting rod 217 and the driven disc 219 will become different due to the internal resistance of the servo motor 215. At this time, interference is likely to occur between the connecting rod 217 and the docking sleeve 220. The presence of the rubber sleeve 218 can cause the connecting rod 217 to deform when interference occurs with the docking sleeve 220, providing a buffer time before separation to prevent the interference between the connecting rod 217 and the docking sleeve 220, so that the connecting rod 217 and the docking sleeve 220 can be separated smoothly, avoiding the friction generated by the mutual interference between the connecting rod 217 and the docking sleeve 220 from affecting the rotation speed of the brake disc 29, and further improving the accuracy of the test data.

[0044] Example 2: Please refer to Figure 1 , Figure 4 and Figure 5 The vehicle condition simulation component includes a heating wire 3, which is installed inside the heat conducting plate 22. A water tank 31 is provided on the upper surface of the test platform 1. Eccentric wheels 32 are fixedly sleeved on both sides of the outer surface of the rotating shaft 28. Support columns 33 are fixedly installed on both sides of the upper surface of the test platform 1. A first limit block 34 is fixedly installed on the top of the support column 33. A second return spring 35 is sleeved on the outer surface of the support column 33. A pressing piece 36 is movably installed on the outer surface of the support column 33. A water splashing piece 37 is fixedly installed on the top of the pressing piece 36. A water splashing hole 38 is provided on the surface of the water splashing piece 37.

[0045] The diameter of the first limit block 34 is larger than the diameter of the support column 33, the bottom of the second return spring 35 is fixedly connected to the upper surface of the detection platform 1, and the top of the second return spring 35 is fixedly connected to the pressing member 36;

[0046] The water tank 31 is located directly below the brake disc 29 , and two water splashing members 37 are distributed on both sides of the brake disc 29 . The water splashing members 37 are located inside the water tank 31 .

[0047] During the vehicle operation, different vehicle conditions will also have different effects on the braking effect of the brake pad 24, among which the effect of the increase in the temperature of the brake pad 24 on the chemical properties of its material;

[0048] When driving in rainy weather, rain splashes onto the surface of the brake pad 24, reducing the friction coefficient between the brake pad 24 and the brake disc 29, and the water causes an oil film to form on the surface of the brake pad 24;

[0049] When the brake pad 24 is at high temperature, it is splashed by rain water, which can easily affect the heat load of the brake pad 24, causing it to deform and reduce the contact area with the brake disc 29;

[0050] In summary, the three common vehicle conditions will affect the braking effect of the brake pad 24, so during the test process, three different vehicle conditions can be divided into three different vehicle conditions for simulation testing, namely, the braking performance of the brake pad 24 at high temperature, the braking performance of the brake pad 24 under splashing water, and the braking performance of the brake pad 24 under high temperature and splashing water. In this way, the braking data of the brake pad 24 under different vehicle conditions can be tested more comprehensively, which improves the comprehensiveness of the test data;

[0051] The water splashing method is to inject water into the water tank 31, and the rotation of the rotating shaft 28 can drive the eccentric wheel 32 to rotate. The eccentric wheel 32 can drive the pressing part 36, so that the pressing part 36 drives the water splashing part 37 to move downward, thereby squeezing the water, so that the water splashes upward to the brake pad 24 through the water splashing hole 38, so that the water splashing test can be realized. The heating method is to heat the heating wire 3, and conduct heat to the brake pad 24 between the heat conducting plate 22 and the heat conducting column 23 to achieve the purpose of heating, and the temperature is controlled by the temperature sensor.

[0052] Example 3: Please refer to Figure 1 , Figure 4 and Figure 6 The detection member 25 is provided with a detection assembly, which includes a marking member 4, which is fixedly mounted on a side of the detection member 25 close to the brake pad 24, and a third return spring 42 is fixedly mounted inside the detection member 25, and a return plate 43 is fixedly connected to one end of the third return spring 42 away from the detection member 25, and the return plate 43 is movably mounted inside the detection member 25;

[0053] A first measuring piece 41 is fixedly mounted on the surface of the reset plate 43 . The first measuring piece 41 is located inside the third reset spring 42 and is movably mounted between the detection piece 25 . A second measuring piece 44 is movably mounted inside the detection piece 25 .

[0054] In the test of the brake pad 24, in addition to the test of its braking effect, the wear resistance and deformation degree of the brake pad 24 after braking are also tested;

[0055] On the basis of Example 2, after different vehicle condition tests, a brightly colored pigment is first applied to the surface of the marking part 4, and then the brake pad 24 is reset by starting the bidirectional hydraulic cylinder 2, so that the brake pad 24 is placed in the detection part 25. Due to the deformation of the brake pad 24, part of it is inside the detection part 25, and part of it is exposed outside. The exposed part will be marked by the color on the surface of the marking part 4, so that the tester can observe the deformation position of the brake pad 24, thereby improving its structure;

[0056] Furthermore, when the brake pad 24 enters the detection piece 25, it will first contact the reset plate 43 and squeeze the reset plate 43, so that the first measuring piece 41 moves out of the interior of the detection piece 25. At this time, the length of the first measuring piece 41 moving out is recorded, and then the second measuring piece 44 is pulled to make the second measuring piece 44 measure the distance between the color mark of the brake pad 24 and its braking surface. This distance is the deformation range, and this distance plus the length of the first measuring piece 41 is the thickness of the brake pad 24 after the test. By comparing with the thickness of the brake pad 24 before the test, the degree of wear of the brake pad 24 can be obtained, which further refines the test data and improves the accuracy of the test data.

[0057] Example 4: Please refer to Figure 1 , Figure 7 and Figure 8 A uniform measurement component is provided on the testing platform 1, and the uniform measurement component includes a placement slot 5, which is opened on the surface of the testing platform 1, and a mold body 51 is provided in the placement slot 5. A telescopic column 52 is movably installed inside the mold body 51, and a second limit block 53 is fixedly installed on the top of the telescopic column 52. An elastic sleeve 54 is provided on the outer surface of the telescopic column 52, and the elastic sleeve 54 is located on one side of the mold body 51.

[0058] During the braking process of the brake pad 24, the brake pad 24 is subjected to normal braking and intermittent braking, i.e., "point braking". "Point braking" may cause uneven wear of the brake pad 24, because each time the brake is applied, the contact time between the brake pad 24 and the brake disc 29 is shorter, which may form local wear points on the brake pad 24.

[0059] During the test, the bidirectional hydraulic cylinder 2 can be started intermittently, so that the brake pad 24 and the brake disc 29 are in intermittent contact until the brake disc 29 stops rotating. In this way, the braking effect of the brake pad 24 during the "point braking" process can be measured. Compared with embodiments 1-3, the "point braking" test wear requires testing of the local wear points formed on its surface;

[0060] After the "point braking" test, it is necessary to align the mold body 51 with the brake pad 24, and make the telescopic column 52 contact with the surface of the brake pad 24, and then press the mold body 51 to make the telescopic column 52 and the brake pad 24 in close contact. At this time, the telescopic column 52 will go deep into the concave surface of the wear point. According to the position of the second limit block 53, after the mold body 51 is pressed, the second limit block 53 close to the mold body 51 is the distribution of the wear point. At the same time, the wear degree of the wear point can be observed through the different positions of the second limit block 53, which further helps the tester understand the material structure of the brake pad 24 and facilitates its continued improvement.

[0061] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
