The present disclosure relates to a method and a combined-propulsion system for high-speed vehicles, which includes a closed tubular guiding structure and a vehicle designed to move through the inside of the tubular structure. The system includes a vacuum system coupled to the tubular structure to provide a safe atmosphere at low pressure, always above the Armstrong limit; electric propulsion means arranged in an initial section of the structure, to accelerate the vehicle to a determined cruising speed; and compressed-air propulsion means arranged on the vehicle, to maintain the cruising speed.

A levitated train is propelled by a system including at least a pair of wheels in cotact with a rail head. The rail head has a horizontal top surface and two vertical sides on either side of the horizontal top surface. A wheel of each wheel assembly has a cylindrical side face with flanges at the top and bottom. The cylindrical face of each of the wheels is in contact with the sides of the rail. The wheel assembly is power driven by a corresponding motor to impart motion to the train. The train is provided with a plurality of such wheel assemblies to be propelled along a rail track. The width of the wheels is greater than the width of the rail head. The flanges on the side of the wheels in a wheel assembly limit the freedom of motion of the train during the levitation.

A moving part of a maglev train, comprising two levitation frames that are arranged at an interval along the direction of travel, the two levitation frames being connected by means of a vertical beam; a peripheral wall of the vertical beam provided with a slot that may reduce the torsional rigidity thereof, being capable of reducing the torsional rigidity of the traditional vertical beam so as to reduce the coupling effect between the two levitation frames that are connected by means of the vertical beam, thereby greatly reducing the difficulty and energy consumption of levitation control. The levitation frames and the train body are provided therebetween with a vertical shock absorber and a horizontal absorber having suitable damping values, the levitation frames and the train body are provided therebetween with horizontal stoppers and vertical stoppers which may prevent excessive horizontal movement, rollover and overturning.
