Abstract
Abstract A magnetic-suspension or levitation vehicle comprises a track having a plurality of substantially continuous rails cooperating with respective systems upon the vehicle, e.g. a reaction rail cooperating with a linear induction motor, a contact rail cooperating with shoes for delivering current to or electrically connecting the vehicle to a central station, an armature rail for a magnetic suspension and/or guide arrangement etc.; at least two and preferably all of the rails are mounted upon common supports which, in turn, are anchored to the track structure at spaced locations along the vehicle path. Thus the relative positions of the rails can be established in a factory and the prefabricated rail assembly erected at the track site as a unit.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
214 words
In a levitation-type vehicle system comprising a track and a vehicle displaceable along a path on said track, said vehicle including at least two of the elements (a) to (e), said elements being (a) electromotor means for propelling said vehicle along said track, (b) electromagnetic suspension means for magnetically supporting said vehicle on said track, (c) electromagnetic guide means for laterally positioning said vehicle relative to said track, (d) contact-shoe means for effecting an electrical connection between said track and said vehicle and (e) emergency support means engageable with said track upon failure of said electromagnetic suspension means, said track comprising a support extending generally continuously along the vehicle path and at least two generally continuous rail members respectively cooperating with said two elements of said vehicle, the improvement which comprises mounting members common to said at least two rail members and anchored to said support at least at spaced-apart locations along said track, said rail members including an electromagnetic suspension armature rail cooperating with the electromagnetic-suspension means of said vehicle, a reaction rail cooperating with said electric motor means of said vehicle, a current-carrying rail cooperating with said contactshoe means of said vehicle, and an emergency support rail engageable with said vehicle upon failure of the electromagneticsuspension means all on said mounting members.
Claim 2
Dependent Claim
214 words
In a levitation-type vehicle system comprising a track and a vehicle displaceable along a path on said track, said vehicle including at least two of the elements (a) to (e), said elements being (a) electromotor means for propelling said vehicle along said track, (b) electromagnetic suspension means for magnetically supporting said vehicle on said track, (c) electromagnetic guide means for laterally positioning said vehicle relative to said track, (d) contact-shoe means for effecting an electrical connection between said track and said vehicle and (e) emergency support means engageable with said track upon failure of said electromagnetic suspension means, said track comprising a support extending generally continuously along the vehicle path and at least two generally continuous rail members respectively cooperating with said two elements of said vehicle, the improvement which comprises mounting members common to said at least two rail members and anchored to said support at least at spaced-apart locations along said track, said rail members including an electromagnetic suspension armature rail cooperating with the electromagnetic-suspension means of said vehicle, a reaction rail cooperating with said electric motor means of said vehicle, a current-carrying rail cooperating with said contactshoe means of said vehicle, and an emergency support rail engageable with said vehicle upon failure of the electromagneticsuspension means all on said mounting members.
Claim 3
Dependent Claim
50 words
The improvement defined in claim 1 wherein each of said mounting members includes a support rail fixed to all of said rail members and extending substantially the full length thereof whereby said rails collectively form a rail assembly prefabricatable in convenient lengths for handling and thereafter mounted upon said support.
