Embodiment Construction

[0026] introduction

[0027] The invention described herein is the result of earlier work by the inventors described in US Patent 6,101,952, the teachings of which are incorporated herein by reference. The designs discussed therein have been used successfully in commercial applications, but improvements for lower complexity and cost are always needed. As will be appreciated from the discussion below, the magnetic switches discussed in said patent are modified herein to work with a variety of levitation and guidance schemes and use electromagnets on the rails to create controllable forces on the vehicle , thereby forcing vehicles to travel in the specified direction at bifurcations and safely maneuver at merging.

[0028] As shown in the figures and discussed below, the illustrated embodiments of the invention utilize magnetic forces to steer or merge vehicles at switch points on guide rails. A vehicle that exerts a force (e.g., lateral force) on a vehicle near a point of mer...

Abstract

A system for switching a transport vehicle comprises: a guideway, a vehicle that moves along the guideway, and a magnetic field source that creates a force on the vehicle to affect motion in a desired direction at a switch. Once the vehicle has started motion through the switch the guidance can be continued by use of permanent magnets until the normal guidance system is effective. The switching scheme can work with any suspension scheme, including wheels and maglev, and can work with any lateral guidance scheme, including horizontal guide wheels and magnetic guidance. The system can be used with very closely spaced vehicles, such as with Personal Rapid Transit, material handling, and elevators with multiple cabs in the same shaft.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of the filing date of US Provisional Application No. 60 / 701,777, filed July 22, 2005, which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to vehicle transportation, and more particularly to methods and apparatus for switching vehicles on guide rails. Background technique [0004] All rails must have means to select between alternate directions of travel. Ordinary trains use switches with mechanically movable tracks, which take seconds to actuate and present maintenance problems. Monorail trains and systems that use magnetic or air-cushion levitation generally require most of the movement of the rails. Some automated people vehicles use wheels with rubber tires for levitation and additional wheels with vertical axles for guidance, the switches being made by moving sections of the guide rail. [0005] For some applicatio...
