[0005] Preferably, the transmission assembly includes four gears, which are respectively fixedly mounted on the output ends of four small motors. An outer gear ring is meshed between the four gears, a rotating ring is fixedly mounted inside the outer gear ring, a positioning ring is fixedly mounted on the circumferential surface of the rotating ring, the positioning ring is slidably mounted inside the positioning ring, and four pushing bars are fixedly mounted at equal distances on the inner wall of the rotating ring.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

The surfaces of the four slide rods 7 are provided with first springs 8, and the two ends of the four first springs 8 are respectively fixedly connected to the inner wall of one end of the slide groove 6 and the slide rod 7.

A card hole 13 is opened at the end of each of the four plug rods 12. A positioning ring 16 is fixedly installed on the inner wall of the transmission disk 9, and four small motors 17 are fixedly installed in a ring at equal distances on one side of the positioning ring 16. Four card rods 22 are equidistantly provided in a ring inside the transmission disk 9. A transmission assembly is provided between the output ends of the four small motors 17, and the transmission assembly is connected to the four card rods 22. When the four small motors 17 are running, power is output to the four card rods 22 through the transmission assembly, so that the four card rods 22 enter or exit the four card holes 13, thereby realizing quick replacement.

[0020] When replacing the brake disc 10, the operator first removes the protective cover 3 and the mounting disc 4 by removing the bolts, and then starts the four small motors 17 to run in the forward direction. When the four small motors 17 run in the forward direction, they all drive the transmission assembly to run in the forward direction. When the transmission assembly runs in the forward direction, the four clamping rods 22 exit the four clamping holes 13 on the four plug rods 12 to release the limit, so that the operator can quickly remove the brake disc 10; when fixing the new brake disc 10, the operator inserts the four plug rods 12 on the new brake disc 10 into the four plug holes 11 on the transmission disc 9, and then the operator starts the four small motors 17 to run in the reverse direction. The reverse operation of the four small motors 17 drives the transmission assembly to run in the reverse direction. When the transmission assembly runs in the reverse direction The four clamping rods 22 are driven to engage in the four clamping holes 13 on the four insertion rods 12 for limiting, thereby quickly completing the installation of the brake disc 10, and finally the protective cover 3 and the mounting disc 4 are installed by bolts; when in use, the electromagnet 5 pushes the transmission disc 9 to move through its own electromagnetic force, and when the transmission disc 9 moves, it drives the slide bar 7 to slide along the inside of the slide groove 6, and at the same time squeezes the four first springs 8, so as to ensure the movement stability of the transmission disc 9 while enabling it to be elastically reset. When the transmission disc 9 moves, it can perform friction braking with the brake disc on the vehicle's drive shaft; this makes it very convenient to disassemble and replace the brake disc 10 of the electromagnetic brake, thereby reducing the workload of maintenance operators and improving work efficiency.

[0021] The transmission assembly includes four gears 18, which are respectively fixedly mounted on the output ends of four small motors 17. The four gears 18 are meshed with an outer gear ring 19. A rotating ring 14 is fixedly mounted inside the outer gear ring 19. A positioning ring 15 is fixedly mounted on the circumferential surface of the rotating ring 14. The positioning ring 15 is slidably mounted inside the positioning ring 16. Four pushing bars 20 are fixedly mounted on the inner wall of the rotating ring 14 at equal intervals; one side of the pushing bars 20 is tightly attached to a contact block 21, and one side of the four contact blocks 21 is fixedly mounted with a card rod 22. The four card rods 22 match the four card holes 13 on the four insertion rods 12. The middle part of the surface of the four card rods 22 is sleeved with a sliding sleeve 25, and the surface of the four sliding sleeves 25 is fixedly mounted with a fixing rod 23. One end of the four fixing rods 23 is fixedly connected to the inside of the transmission disk 9. The upper part of the surface of the four card rods 22 is provided with a second spring 24, and the two ends of the four second springs 24 are respectively fixedly connected to the contact block 21 and the sliding sleeve 25.

[0022] During disassembly, the operator starts the four small motors 17 to rotate in the forward direction. When the four small motors 17 rotate in the forward direction, they all drive the outer ring gear 19 to rotate through the gear 18. When the outer ring gear 19 rotates, it drives the four pushing bars 20 to gradually loosen the four contact blocks 21. As a result, the elastic force of the four second springs 24 drives the clamping rods 22 to move along the inside of the sliding sleeve 25, thereby causing the four clamping rods 22 to withdraw from the inside of the four clamping holes 13 on the four insertion rods 12 and release the limit.

[0023] During installation, the operator starts the four small motors 17 to rotate in the reverse direction. The four small motors 17 rotate in the reverse direction and drive the rotating circle 14 to rotate through the outer ring gear 19. When the rotating circle 14 rotates, it drives the positioning ring 15 to rotate along the inside of the positioning ring 16, thereby increasing the stability of the rotating circle 14 during rotation. When the rotating circle 14 rotates, it pushes the four contact blocks 21 at the same time through the four pushing bars 20. When the four contact blocks 21 are pushed, they drive the clamping rod 22 to move along the inside of the sliding sleeve 25 and squeeze the four second springs 24 at the same time. When the four clamping rods 22 move, they will be stuck in the inside of the four clamping holes 13 on the four insertion rods 12 to limit them.
