[0022] 3. A diverter device and a ring are provided. When the train is braked, the high-pressure gas blown out by the pump flows into the two rings through the diverter device, thereby pushing the piston plates in the rings to slide to both sides at the same time. At this time, the piston plates will drive the brake pads to fit the inner wall of the wheel through the push rod to brake. By braking the four wheels at the same time, the braking stability and efficiency are improved, ensuring that the train remains stable during the braking process.

[0023] 4. A main airbag and an auxiliary airbag are provided. When the front of the vehicle is accidentally separated from the car body, the connecting rod will reset and move under the elastic force of the second spring, thereby squeezing the main airbag, causing the main airbag to deform, so that the gas in the main airbag is transported to the auxiliary airbag through the pipeline, causing the auxiliary airbag to expand, and at the same time pushing the two limit rods to slide to both sides. At this time, the limit rods will engage with the gear blocks on the fixed ring, thereby locking the wheels and stopping the wheels from rotating. It is very important to ensure the safety of passengers and surrounding people, and effectively reduces the risks that may be caused by the car body detaching. BRIEF DESCRIPTION OF THE DRAWINGS
