Auxiliary propulsion for magnetically levitated vehicle

摘要

A transportation system for levitated propulsion of a vehicle relative to a guideway having first sections for linear vehicle travel and second sections for turning movements of the vehicle is disclosed. The system includes AC-excited magnets for low-speed levitated travel in pivot turns, guideway switching areas, and curving sections of guideway including superelevated structure. The system includes guideway mounted primary electrical members in pivot turns and guideway switching areas. In switching areas vehicle steering is provided by null flux loops located on the guideway structure. In the curving sections of guideway, there is a dovetail trough containing secondary electrical members that interact with deployable primary electrical members on the vehicle which are independently positioned and powered for propelling the vehicle along the curving sections.
