Suspension frame and maglev train with direct transmission traction linear motor in the middle

Abstract

The invention discloses a suspension frame and a magnetic levitation train with a direct transmission type traction linear motor in the middle. The suspension frame includes a traction linear motor, a motor boom, a pair of suspension modules and a pair of crossbeams. The traction linear motor is arranged in parallel between the pair of suspension modules, and a pair of crossbeams are respectively arranged at both ends of the suspension module, and each crossbeam is connected to a Between the suspension modules, the traction linear motor is hung on a pair of beams through the motor suspender. At least one set of anti-roll decoupling mechanism is installed on both sides of the traction linear motor. One end of the anti-roll decoupling mechanism is hinged to the traction linear motor, and the One end is hinged with the suspension module, and the traction linear motor is equipped with a traction assembly for connecting the car body. The magnetic levitation train comprises a plurality of car bodies and a plurality of above-mentioned suspension frames in the middle of the direct transmission traction linear motor, and the car bodies are arranged on the suspension frames. The suspension frame and the magnetic levitation train placed in the middle of the direct transmission type traction linear motor have the advantages of simple structure, convenient installation and maintenance, high traction efficiency and strong cornering ability.

Description

technical field [0001] The invention relates to the technical field of magnetic levitation trains, in particular to a suspension frame and a magnetic levitation train with a direct transmission type traction linear motor in the middle. Background technique [0002] The main difference between maglev trains and ordinary wheel-rail vehicles is the generation mechanism of traction force, guiding force and vehicle support force. The non-contact electromagnetic force between the on-board electromagnet of the maglev train and the inverted U-shaped track replaces the supporting force and guiding force generated by the contact between the wheel and the track of the wheel-rail vehicle; the non-contact electromagnetic force between the primary and secondary of the linear motor Traction replaces the adhesion between the wheel and rail. The traction force generated by the linear motor is not limited by the wheel-rail adhesion, and its climbing ability and curve passing ability are much...

Problems solved by technology

This is because the suspension frame in the middle of the traction linear motor 1 transmits the motor thrust to the left and right suspension modules 2 through the main arm 7, and the main arm 7 is fixed to the traction linear motor 1. This force transmission method will cause the traction linear motor 1 to be affected. Influenced by the front and rear positions of the left and right suspension modules 2, the parallelogram formed by the left and right suspension modules 2 and the anti-roll decoupling mechanism changes rhombically and cannot maintain a rectangle when cornering, so that the direction of the motor is basically parallel to the car body 8 instead of follow the track

The simulation data shows that the yaw angle between the motor and the track even reaches 6.5°, which will have an adverse effect on the thrust control of the motor when cornering
