A kind of magnetic levitation bogie and train

Abstract

The invention relates to a magnetic levitation bogie and a train. The bogie includes an upper frame at the upper part, two lower frames at the lower part, a suspension device and a track induction device. The upper frame and the lower frame are hingedly connected by a connecting device. Suspension devices are respectively installed on the bottoms of both sides of the frame, and track induction devices are installed on the bottom surface of the middle part of the lower frame; the lower frame is provided with a limit mechanism for restricting the movement of the suspension device. The invention integrates the functions of suspension, driving and guidance, and simplifies the structure of the bogie while having multiple functions; both the suspension device and the side beam are installed in the form of a combination of a limit groove and a limit slider, and the disassembly is more convenient , the maintainability is higher; the number of fixed parts is reduced, the stability is higher, and the installation time is shorter; the lateral and longitudinal displacement of the suspension device is limited by the limit mechanism, which improves the stability of the device and makes the train run safer .

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.
