Maglev bogie and train

Abstract

The invention relates to a maglev bogie. The maglev bogie comprises an upper framework, two lower frameworks, levitation devices and track sensing devices, wherein the upper framework is positioned atthe upper part, and the two lower frameworks are positioned at the lower parts; the upper framework is connected with the lower frameworks through connecting devices in a hinged manner; the levitation devices are correspondingly mounted at the bottoms of the two sides of the lower frameworks; and the track sensing devices are mounted on the bottom surfaces of the middle parts of the lower frameworks. According to the maglev bogie, basic functions of maglev vehicle levitation driving and guiding functions are integrated; by using bearing hinging structures to connect the upper framework with the lower framework, a single steering mechanism does not need to be specially arranged; and therefore, the structure is simplified while multiple functions are realized; as the maglev bogie is prone to being manufactured by using a lightweight material, the weight of a superconducting maglev vehicle running mechanism can be effectively reduced; and as a low temperature liquid filling system is generally placed on the ground under the vehicle, the maglev bogie is beneficial for mounting more low temperature filling containers in the running mechanism and the bogie to fill more low temperature liquids, and therefore, a greater levitation force is realized. The invention further relates to a maglev 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...

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
