[0041] Specifically, the servo motor 4 drives the transmission rod 5 and the mounting plate 6 to rotate, which in turn causes the test disc 7, mounted on the right side of the mounting plate 6, to rotate at high speed, simulating the actual rotation state of the brake disc when a car is in motion. Then, the braking system, consisting of a hydraulic pump 8, oil pipe 9, loading cylinder 10, piston 11, and brake pads 12, begins to operate. The hydraulic pump 8 starts, delivering high-pressure oil to the loading cylinder 10 through the oil pipe 9.

Two side ears 203 are fixedly connected to the outer wall of the mounting seat 202, providing a sliding track for the bolt 204, ensuring that the bolt 204 can stably drive the mounting seat 202 to move. The inner walls of both side ears 203 are slidably connected to... Bolt 204 slides within side lug 203 to flexibly adjust the position of mounting base 202. Nut 205 is threaded onto the outer wall of both bolts 204. Nut 205 engages with bolt 204 and, after mounting base 202 is adjusted to the appropriate position, it is fixed onto mounting plate 6. Limiting groove 206 is formed on the outer wall of mounting plate 6.

[0043] Specifically, when installing the test plate 7, adjust the position of the mounting base 202 according to the size of the test plate 7. First, loosen the nut 205 to disengage it from the fixing base 201. At this time, the bolt 204 can slide freely on the inner wall of the side lug 203. Then, slide the mounting base 202 left and right on the mounting plate 6. The movement of the mounting base 202 is achieved by the cooperation of the mounting bolt 26 and the limiting groove 206.

The wear-resistant plates 24 can enhance the wear resistance of the brake pads 12, extend the service life of the brake pads 12, and improve the stability of the braking system during simulated braking. Multiple anti-slip grooves 25 are opened on the outer walls of the two wear-resistant plates 24. The anti-slip grooves 25 increase the friction between the wear-resistant plates 24 and the test disc 7, making the braking effect during simulated braking closer to the real situation.

[0045] Specifically, in terms of simulation environment, the charging port 20 at the top of the sand tank 16 facilitates the addition of sand particles, which, in combination with the dust simulation assembly, can effectively simulate a sand-dust environment. The water inlet 23 of the water tank 13 can supplement moisture in a timely manner, and the sprinkler 14 can simulate a rain environment to comprehensively detect the performance of the brake disc under different environments. In terms of equipment protection and stable operation, the partition 21 on the outer wall of the support plate 3 can prevent the servo motor 4 from being disturbed by water mist and sand dust, ensuring the stability of the power system. The inductor 22 senses the operating parameters of the equipment in real time, providing data support for automated operation, improving detection efficiency and accuracy. In terms of simulating brake performance, the wear-resistant sheet 24 of the brake pad 12 enhances wear resistance and prolongs its service life, ensuring the stability of the braking system. The anti-skid groove 25 on the wear-resistant sheet 24 increases the friction with the disc to be tested 7, making the simulated brake effect more realistic, thereby improving the reliability of the detection of the friction and wear performance of the brake disc and providing more accurate data for evaluating the performance of the brake disc.
