Magnetic suspension bogie and train

Abstract

The invention relates a magnetic suspension bogie. The bogie comprises an upper framework located at the upper part, two lower frameworks located at the lower part, suspension devices and rail sensingdevices, wherein the upper framework and each lower framework are connected through a connecting device in a hinged and moving mode, the suspension devices are arranged at the bottoms of the two sides of each lower framework correspondingly, the rail sensing devices are arranged on the bottom surfaces of the middles of the lower frameworks, the two sides of the upper framework extend outwards toform mounting parts correspondingly, and air spring mounting seats are arranged on the mounting parts. According to the bogie, basic functions of suspension, drive and guide of a magnetic suspension train are integrated, so that the structure is simplified while the various functions are achieved; light-weight material is adopted for manufacturing, so that a low-temperature holding container can be used for containing more low-temperature liquid, and larger suspension force can be achieved; the upper framework is reasonable in structure, so that a framework body can be provided with connectorsof various devices, and the light weight is achieved on the premise of ensuring the strength; and air springs are arranged on the mounting parts on the two sides of the upper framework, so that a train body is effectively supported. The invention further relates to the magnetic suspension train.

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, since 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. From the perspective of light weight and improved levitation efficiency, consideration should Simplify the structure as much as possible, integrate the three major functions of suspension, drive and guidance, and develop a running mechanism for superconducting maglev vehicles
