Maglev bogie and train

Abstract

The invention relates to a maglev bogie and a train. The maglev bogie comprises an upper framework, two lower frameworks, levitation devices and track sensing devices, wherein the upper framework is positioned at the upper part; the two lower frameworks are positioned at the lower part; the upper framework is in hinged connection with the lower frameworks through connecting devices; the levitationdevices are correspondingly mounted at the bottoms of the two sides of the lower frameworks; the track sensing devices are mounted on the bottom surfaces of the middle parts of the lower frameworks;and limiting mechanisms used for limiting the movements of the levitation devices are arranged on the lower frameworks. According to the maglev bogie, as levitation, driving and guiding functions areintegrated, the structure of the bogie is simplified while multiple functions are realized; the levitation devices and side beams are all mounted in the combination form of limiting grooves and limiting slide blocks so that the detaching is more convenient and the maintainability is higher; the use number of fixing pieces is reduced, the stability is higher, and the mounting time is shorter; through the limiting mechanisms, the transverse and longitudinal displacement of the levitation devices is limited so that the stability of the device is improved; and therefore, the train running is muchsafer.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to a magnetic levitation bogie and a train. Background technique [0002] At present, maglev trains can be divided into constant conduction magnetic attraction (EMS) and superconducting magnetic repulsion (EDS) according to different levitation methods. The constant conduction magnetic suction type utilizes the constant conduction magnets (suspension electromagnets) installed on the bogies on both sides of the vehicle and the magnets laid on the line guide rails, and the attraction generated by the magnetic field makes the vehicle float. The superconducting magnetic repulsion type is to install a superconducting magnet (placed in a liquid nitrogen or liquid helium storage container) at the bottom of the vehicle, and lay a series of aluminum ring coils on both sides of the track. When the train is running, the coil on the train (superconducting magnet) is passed a current to gener...

AI Technical Summary

Problems solved by technology

However, for superconducting maglev trains, because its levitation principle is different from that of conventional maglev trains, multiple devices containing low-temperature coolant need to be suspended, which increases the weight of the running mechanism, takes time to install, and has poor maintainability in subsequent disassembly and assembly.
