Guide mechanism suitable for four-suspension-module magnetic levitation vehicle

Abstract

The invention discloses a guide mechanism suitable for a four-suspension-module magnetic levitation vehicle. The mechanism comprises a first pair of sliding tables, a second pair of sliding tables, athird pair of sliding tables, a fourth pair of sliding tables and a fifth pair of sliding tables which are arranged in a longitudinal direction, and each pair of sliding tables is arranged in a transverse direction. The guide mechanism comprises a first guide structure and a second guide structure which are symmetrically arranged along a longitudinal center line and a transverse center line; two transverse end parts of a long T-shaped rotating arm and two transverse end parts of a short T-shaped rotating arm of the first guide structure are connected through two pull rods, and the third end part of the long T-shaped rotating arm is hinged with one ends of two first elastic connecting pieces; and the third end part of the short T-shaped rotating arm is hinged with one ends of the two secondelastic connecting pieces. A problem of rigid connection of transverse pull rods of an existing guide mechanism is effectively solved, coupling between the 1-position sliding table, the 3-position sliding table and the 5-position sliding table is effectively reduced through elastic deformation of the elastic connecting pieces, all the suspension modules are kept in good postures when going in andout of a curve, and an internal load of the guide mechanism is effectively reduced when going in and out of the curve.

Description

technical field [0001] The invention relates to a guide mechanism suitable for a four-suspension module maglev vehicle, and belongs to the technical field of maglev vehicles. Background technique [0002] The guide mechanism is a unique structure of low- and medium-speed maglev trains, and it is also an important component. It mainly includes two sets of rotating arms, two sets of long tie rods and four sets of transverse tie rods. The long pull rod is connected with the rotating arm, and the rotation center of the rotating arm is connected with the car body, thereby forming a realizable parallelogram frame, and the rotating arm is hinged with the slide table in the suspension frame unit through the transverse tie rod. When the train passes the curve, the suspension module slides relative to the car body, driving the transverse tie rods and the parallelogram structure to move, so that the suspension modules are arranged radially along the curve when passing the curve, and th...

AI Technical Summary

Problems solved by technology

[0006] ①The internal load of the guiding mechanism is very large;

[0007] ②The lateral load of the air spring is transmitted to the suspension module to affect the attitude of the suspension frame. The attitude of the first suspension module is not conducive to the vehicle entering and exiting the small radius curve
