Suspension brake integrated component and device and high-speed sled vehicle suspension brake system

The invention provides a suspension braking integrated component and device and a high-speed sledge vehicle suspension braking system, and belongs to the technical field of spaceflight or traffic. The suspension braking integrated component comprises a braking unit and suspension units, and the suspension units are arranged on the two sides of the braking unit; the suspension unit and the braking unit generate suspension force and braking force through the action with the moving suspension body, and braking of the suspension body in the suspension moving process is achieved. The suspension and brake integrated component is simple in structure, integrates the functions of electric suspension and eddy current brake, and further improves the brake force, so that the high-speed suspension body realizes suspension movement and high-speed brake while moving, the damage to the suspension body caused by abrasion and rapid heating due to mechanical brake is avoided, and the service life of the suspension body is prolo
