| 摘要 |
A transportation system for levitated propulsion of a vehicle (10) relative to a guideway (12) having first sections for linear vehicle travel and second sections for turning movements of the vehicle (10) is disclosed. The system includes AC-excited magnets (26, 30) for low-speed levitated travel in pivot turns, guideway switching areas, and curving sections of the guideway (12) including superelevated structures. The system includes guideway mounted primary electrical members (117, 119, 121, 38) in pivot turns and guideway switching areas. In switching areas, the vehicle steering is provided by null flux loops (62, 64) located on the guideway structure. In the curving sections (11B) of guideway (12), there is a dovetail trough (108, 110) containing secondary electrical members (95, 97) that interact with deployable primary electrical members (112) on the vehicle (10) which are independently positioned and powered for propelling the vehicle (10) along the curving sections (11B).
