Abstract

An overhead transportation system comprises one or more roller tracks joined in a superimposed manner to one or to both sides of a plurality of pillars or columns which form the supporting assembly of the system. Each of the roller tracks is formed of two U-shaped elements arranged parallelly to each other and whose cavities face each other. Each pair of U-shaped elements are connected to the supporting assembly parallel to the vertical axis thereof or slightly inclined thereto. A movable vertebrated or segmented train element includes a series of interconnecting compartments which are pivotally joined to each other in an alternate manner, about vertical axles at the surface thereof nearest to the roller tracks, and about horizontal axles at the base thereof. Tilting, during high speed travel around curves, of the compartments is not allowed, but tilting of the frames of the seats, completely independent of the compartments, is allowed, such tilting being activated hydraulically or mechanically to achieve the required inclination. Damping is effected by the flexible or resilient surface of the roller track and the fastening and guide assemblies, and may be aided by the provision of leaf springs incorporated therein.

Dependent claims

An elevated transportation system comprising:

a plurality of vertical support columns positioned spaced along a desired path;
at least one roller track attached to said support columns, said track comprising upper and lower U-shaped elements extending parallel to each other and having open channels facing each other;
a segmented movable train element mounted to move along said track and comprising a plurality of successively pivotally connected compartments;
alternate first junctions, between adjacent of said compartments, comprising pivotal connections about vertical axles at lateral sides of said compartments closest to said track, said first junctions comprising means for accomodating horizontal curves in said track;
alternate second junctions, intermediate said first junctions, between adjacent of said compartments, comprising pivotal connections about horizontal axles at the bottoms of said compartments, said second junctions comprising means for accomodating vertical curves in said track;
each of said vertical axles having at the upper and lower ends thereof guide wheels which respectively ride within and against said upper and lower U-shaped elements of said track;
and
each of said horizontal axles having at the end thereof nearest said track a traction wheel contacting said lower U-shaped element of said track.
