Abstract

The invention discloses a superconducting electric electromagnetic hybrid maglev train, which comprises L-shaped suspension frames and an I-shaped ground rail, and is characterized in that the upper end of each suspension frame is connected with a train body through an air spring; the suspension frames are arranged on the two sides of the ground rail, and the suspension frames and the ground railare arranged at intervals. A plurality of superconducting magnets is arranged at the lower end of each suspension frame. An 8-shaped upper-layer suspension coil and an 8-shaped lower-layer suspensioncoil are arranged at the upper end and the lower end of the ground rail respectively, an upper-layer power generation coil and a lower-layer power generation coil are arranged at the lower end of thesuspension frame, and the upper-layer suspension coil is electrically connected with the lower-layer suspension coil; and a propelling coil is arranged above the upper-layer suspension coil. The invention has the advantages of large operation air gap, self-stabilization, good suspension guiding dynamic performance, better curve passing capacity, higher superconducting magnet magnetic field utilization rate and lower track construction cost.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a superconducting electric-electromagnetic hybrid maglev train. Background technique [0002] As a new standard rail transit technology, maglev relies on the electromagnetic force between the car body and the track instead of mechanical contact force to balance the weight of the car body, which can fundamentally eliminate contact friction and wear; the use of linear motor traction drive and power generation can avoid The wheel-rail system faces the problems of the limit of adhesion traction and the restriction of pantograph-catenary flow. This makes maglev one of the main directions for the development of higher-speed rail transit technology. [0003] Electromagnetic levitation relies on the electromagnetic attraction between the on-board electromagnet and the magnetic track to make the car body float above the track and can be suspended statically. The typical feature of ...
