Movable cantilever structure of magnetic suspension train

Abstract

A movable cantilever structure of a magnetic suspension train comprises a C-type cantilever support. The upper portion of the cantilever is rotationally connected with a suspension support frame through a vertical rotating shaft. The lower portion of the cantilever is rotationally connected with an electromagnet installing arm through a horizontal rotating shaft. The horizontal rotating shaft is perpendicular to the electromagnet installing arm. The two sides of the C-type cantilever support are provided with a pair of transverse dampers and a pair of longitudinal dampers. The two ends of each transverse damper are respectively connected with the C-type cantilever support and the suspension support frame. The two ends of each longitudinal damper are respectively connected with the C-type cantilever support and the electromagnet installing arm. The movable cantilever structure of the magnetic suspension train enables single-cantilever control to be achieved and greatly simplifies the complexity and the technical difficulty of the mechanical decoupling of a suspension support of the prior magnetic suspension vehicle. The parameter matching of dampers arranged on drawbars are simplified and singularized. The ramp through capacity and the curve passage capacity of the suspension support are improved. The flexibility, the reliability and the safety are improved. The movable cantilever structure of the magnetic suspension train is significant in promoting the engineering of magnetic suspension technology and rapidly achieving the commercialization of magnetic suspension vehicles.

Description

technical field [0001] The invention relates to a movable cantilever structure of a maglev train, which belongs to the field of vehicle body structure design. Background technique [0002] With the rapid development of rail transit, the urbanization process is advancing rapidly, but it also leaves a safety hazard for rail transit. With the occurrence of a particularly serious railway traffic accident on the 7.23 Yongwen Line, people have unprecedented expectations for safer, more environmentally friendly, more energy-saving, and more convenient maglev transportation. [0003] At present, in the suspension frame of domestic and foreign maglev vehicles, in order to solve the problem of passing through the curves and ramps of the line, complex mechanical decoupling structures and complex shock absorption and damping system devices are used. The technology is complex and there are many mechanical failure factors. High requirements on lines and high input costs. Contents of th...
