[0022] Working principle: First, when the monorail vehicle brakes suddenly, the hydraulic push rod 204 in the auxiliary deceleration device 2 is started, and the telescopic end of the hydraulic push rod 204 is limited by the limit seat 207 to push the transmission rod 205 to drive the brake pad 206 to move downward, so that the bottom of the brake pad 206 is in contact with the top of the brake disc 203. At the same time, while the stabilizing wheel 104 drives the brake disc 203 to rotate, the brake disc 203 is squeezed by the brake pad 206, resulting in a reduced speed of the brake disc 203 during rotation, thereby effectively reducing the rotation speed of the stabilizing wheel 104. The driving of the brake pad 206 by the hydraulic push rod 204 in the auxiliary deceleration device 2 effectively improves the operation safety and stability of the monorail vehicle, especially in sudden situations such as sudden stop and emergency braking of the train, the auxiliary deceleration mechanism can play a role in deceleration in a timely and accurate manner, thereby reducing the impact during vehicle operation and ensuring the personal safety of passengers and the operation safety of the train.

[0023] Secondly, when replacing the brake pad 206, manually rotate the threaded rod 4022 in the forward direction, and the rotation of the threaded rod 4022 drives the block 4023 to move upward under the limit of the limit rod 4024, until the bottom of the block 4023 is completely pulled out of the top of the limit groove 2062, thereby realizing the left and right limit of the brake pad 206, and then pull the brake pad 206 outward so that the insertion grooves 2061 on both sides of the outer wall of the brake pad 206 slide outward inside the installation groove 4011, until the brake pad 206 is completely pulled out from the inside of the shell 401, The new brake pad 206 can be inserted into the interior of the installation groove 4011, and then the threaded rod 4022 is rotated in the opposite direction to drive the block 4023 to be inserted into the interior of the limiting groove 2062, so as to realize the disassembly and installation of the brake pad 206, and then the brake pad 206 is fixed by the shell 401 and the limiting component 402 in the fixing component 4, so as to realize the disassembly and replacement of the brake pad 206, and it is convenient for the brake pad 206 to be replaced in time when it is worn out during long-term use, so as to ensure the effectiveness of the brake pad 206 during use, and further improve the practicability of the device during use.

[0024] Finally, when adjusting the position of the stabilizing wheel 104, the driving motor 3041 in the driving assembly 304 is started, and the threaded shaft 3042 is driven to rotate by the driving motor 3041, and the threaded sleeve 303 is driven to move horizontally through the rotation of the threaded shaft 3042, so that the push plate 302 slides horizontally on the inner side of the limiting slide groove 301, and the movement of the push plate 302 pushes the front end of the fixed seat 201 to move. The movement of the front end of the fixed seat 201 realizes the adjustment of the position of the stabilizing wheel 104, and realizes the adjustment of the position of the stabilizing wheel 104, so that when the stabilizing wheel 104 needs to be inspected and repaired, the stabilizing wheel 104 can be extended out separately, which improves the convenience during the maintenance process and further improves the practicality of the device when in use.
