Magnet and motor integrated module of middle-low speed maglev train

Abstract

The invention relates to a magnet and motor integrated module of a middle-low speed maglev train. The magnet and motor integrated module comprises a linear motor assembly, a suspension magnet assembly, a motor longitudinal beam and a pair of supporting arms which are integrated into a whole module, wherein the pair of supporting arms are each in an inverted-L shape. The motor longitudinal beam isconnected with the pair of supporting arms along the two ends of a longitudinal beam body of the motor longitudinal beam to form a supporting structure. The linear motor assembly is hung and mounted at the tops of the supporting arms. The bottoms of the supporting arms and the suspension magnet assembly are mounted in a matched mode. Compared with the prior art, the magnet and motor integrated module is advantageous in that the linear motor assembly and the suspension magnet assembly are integrated through the supporting arms and the motor longitudinal beam, the enough position dimension accuracy is ensured through positioning datum and the fine-adjusting function among all parts, in addition, the integrated whole module participates in overall integration and overhaul of a vehicle, the integration and overhaul process of the vehicle is simplified, the assembly quality is ensured, a basic guarantee is provided to commissioning and operation control of the vehicle, and great convenienceis also brought for vehicle maintenance and overhaul.

Description

technical field [0001] The invention relates to the field of levitation magnets and linear motors of medium and low speed maglev systems, in particular to a magnetomotor integrated module for medium and low speed maglev trains. Background technique [0002] Medium and low-speed maglev transportation technology relies on electromagnetic force to levitate trains and uses linear motors to drive rail transit technology. The running speed is 100-120 kilometers per hour. It has low operating noise, good environmental performance, comfortable ride, strong climbing ability, and small turning radius. , high safety and reliability, low operation and maintenance costs, and strong adaptability to the terrain environment. It is suitable for transportation connections between large and medium-sized cities, short-distance cities and tourist attractions. [0003] There are obvious differences between the medium and low speed maglev vehicle system and the traditional rail vehicle system. T...

Problems solved by technology

[0004] The levitation magnet and linear motor assembly of the existing medium and low-speed maglev vehicles are independent separate parts. In particular, the linear motor assembly is suspended from the longitudinal beam of the suspension frame by 8 adjustable screws. During the maintenance and repair process of the vehicle, Due to the lack of positioning and measurement benchmarks, the operability of the adjustment mechanism of the linear motor is relatively poor, and it may be improperly operated, which makes it difficult to ensure the clamp distance of the linear motor and the levitating magnet.

In addition, due to the lengthened size of the linear motor, it is more difficult to assemble and disassemble. For example, when a certain type of low-speed maglev vehicle needs to replace a certain linear motor, the motors in front of it must be removed in turn, and the train can only be replaced after the train leaves. The maintenance operation is very difficult. inconvenient
