Abstract
Abstract A suspended railway system utilizing a magnetic guide for vehicles and at least a support beam which is partly enclosed by the vehicle as a support member along the path of travel. The suspended railway system has, in the area of a switch, at least three support beams which are tapered on one side toward the central portion of the switch and terminate at the central portion. A first support beam extends from the switch entrance into the central portion of the switch and is arranged between the remaining two support beams. The remaining two support beams extend from the central portion of the switch to the switch exit. The switching function from one path of travel to another path of travel is accomplished by electromagnetic principles.

Claim 1
Independent Claim
340 words
In a switching zone for a magnetic suspended railway having means defining a switch entrance and a pair of switch exits and means defining a support beam at said switch entrance and said switch exits on which at least one vehicle having a pair of laterally spaced means defining driving legs thereon is supported in a suspended position by means defining conductive rails and guided by first guide magnets positioned relative to said conductive rail means, said first guide magnets being mounted on opposed surfaces of said driving legs, said conductive rail means being mounted on oppositely facing surfaces of said support beam means outside of said switching zone, said support beam means being partly enclosed by said driving legs on said vehicle, the improvement comprising wherein, within said switching zone, said support beam means comprises at least three support beams which are each tapered on one side toward a central portion of said switching zone and terminate at said central portion, a first support beam including support means extending from said switch entrance into said central portion and between the remaining two of said support beams, said remaining two of said support beams extending from said central portion to one of said switch exits, the spacing between said first support beam and said remaining two support beams in said central portion being equal, means in said central portion of said switching zone defining a pair of second guide magnets, one on each side of said first support beam, for establishing a magnetic coupling with said first guide magnets in said central portion and on at least one side of said vehicle, said first and second guide magnets having identical polarity, means defining first magnetically conductive guide rails on the opposite side of said driving legs from said second guide magnets and means defining a pair of third guide magnets for establishing a magnetic coupling with said first conductive guide rail means in said central portion and on at least the other side of said vehicle from said one side.
Claim 2
Dependent Claim
340 words
In a switching zone for a magnetic suspended railway having means defining a switch entrance and a pair of switch exits and means defining a support beam at said switch entrance and said switch exits on which at least one vehicle having a pair of laterally spaced means defining driving legs thereon is supported in a suspended position by means defining conductive rails and guided by first guide magnets positioned relative to said conductive rail means, said first guide magnets being mounted on opposed surfaces of said driving legs, said conductive rail means being mounted on oppositely facing surfaces of said support beam means outside of said switching zone, said support beam means being partly enclosed by said driving legs on said vehicle, the improvement comprising wherein, within said switching zone, said support beam means comprises at least three support beams which are each tapered on one side toward a central portion of said switching zone and terminate at said central portion, a first support beam including support means extending from said switch entrance into said central portion and between the remaining two of said support beams, said remaining two of said support beams extending from said central portion to one of said switch exits, the spacing between said first support beam and said remaining two support beams in said central portion being equal, means in said central portion of said switching zone defining a pair of second guide magnets, one on each side of said first support beam, for establishing a magnetic coupling with said first guide magnets in said central portion and on at least one side of said vehicle, said first and second guide magnets having identical polarity, means defining first magnetically conductive guide rails on the opposite side of said driving legs from said second guide magnets and means defining a pair of third guide magnets for establishing a magnetic coupling with said first conductive guide rail means in said central portion and on at least the other side of said vehicle from said one side.
Claim 3
Dependent Claim
63 words
The improvement according to claim 1, wherein said conductive rail means is composed of magnetically conductive support rails and second magnetically conductive guide rails, said vehicle being supported in a suspended position by a magnetic coupling between means defining said conductive support rails and first support magnets and guided by said first guide magnets positioned relative to said second magnetically conductive guide rails.
Claim 4
Dependent Claim
80 words
The improvement according to claim 2, wherein said conductive support rails are mounted on opposite sides of said first support beam including said support means and extend into said central portion of said switching zone and terminate at said central portion, said conductive support rails being also mounted on one side of said remaining two of said support beams remote from said support means and extend into said central portion of said switching zone and terminate at said cental portion.
Claim 5
Dependent Claim
43 words
The improvement according to claim 3, wherein said second magnetically conductive guide rails are mounted on said one side of said remaining two of said support beams and extend into said central portion of said switching zone and terminate at said central portion.
Claim 6
Dependent Claim
90 words
The improvement according to claim 2, wherein said second guide magnets are mounted on opposite sides of said first support beam and opposing said first guide magnets on said driving legs, said second guide magnets extending from an external portion of said central portion of said switching zone into said central portion and terminating thereat, said second magnetically conductive guide rail means are mounted on oppositely facing surfaces of said first support beam and terminate at the location where said second guide magnets begin and extend into said central portion.
Claim 7
Dependent Claim
82 words
The improvement according to claim 2, wherein said conductive rail means further comprises second magnetically conductive support rails and second support magnets, said vehicle being supported in a suspended position by a magnetic coupling between said second conductive support rails and said second support magnets, said magnetic coupling between one of said first mentioned support rails and said first support magnets supporting one side of said vehicle whenever said magnetic coupling exists between said second support rails and said second support magnets.
Claim 8
Dependent Claim
84 words
