Guideway

Abstract

A guideway for track-bound vehicle such as a magnetic suspension railway vehicle includes a plurality of serially arranged carriers. Each carrier further includes a guideway slab having vehicle guidance elements arranged thereon, the guideway slab supported on a web oriented in a longitudinal direction of carrier and extending downwardly from the guideway slab. A foundation member bears the weight of the carriers relative to an underlying surface upon which the guideway is constructed. The webs extend from the guideway slab towards the foundation member. Resilient members are disposed between the foundation member and the underlying surface that resiliently support the foundation member in a vertical direction relative to the underlying surface.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a guideway for a track-bound vehicle, especially a magnetic suspension railway, with several serially arranged carriers, in which each carrier comprises a guideway slab with guide elements for the vehicle arranged on it. The guideway slab is held at a distance from a foundation by at least one web that runs in the longitudinal direction of the carrier and projects in the assembled position substantially downward from the guideway slab.BACKGROUND[0002]DE 10 2004 015 495 A1 teaches a track for a magnetic suspension railway with a shunt arrangement in which carriers comprise guide elements for the vehicle that are arranged on a guideway slab. The guideway slab is fastened on a web arranged on an apparatus for oscillation damping. The oscillation damping is provided in the design in order to allow a calm running operation of the vehicle in the shunt. The carrier is fastened to this end directly on the oscillation damping appar...

AI Technical Summary

Benefits of technology

[0006]According to the invention, the guideway, which comprises a guideway slab and a web, is fastened on a foundation supported in the vertical direction in a resilient manner on the base. Thus, not only the weight of the carrier but in addition also the mass of the foundation, serves as mass for the mass-spring system. According to requirements and independently of the shape of the carrier, the foundation can be designed in such a manner as regards mass that it produces a reliable oscillation damping. This creates a system that allows a calm and comfortable operation of a vehicle, in particular of a magnetic suspension railway, on the carrier of the guideway.

[0019]The carriers used in the guideway in accordance with the invention are preferably produced from finished concrete parts. Even the foundation can be constructed as a finished concrete part or on-site concrete part. Of course, even other carriers are possible that are manufactured from steel or combined from steel and concrete. The carrier can be constructed in one piece or several pieces, for example with separate webs fastened to the guideway slab. As a result of the construction of the guideway in accordance with the invention with a resiliently supported foundation on which the carriers are arranged, even light carrier embodiments can be optimally designed with regard to the mass-spring system.

Problems solved by technology

This arrangement has the disadvantage that the carrier must be designed in a very filigree-like manner in the shunt in order to allow the bending for a shunt switching.

Problems can arise in the longitudinal expansion of the carriers by the connection of the carriers to each other.

A disadvantage is the different deflection of adjacent guideway slabs during the passage of a vehicle if the guideway slabs are not firmly connected to each other.

In addition, in this design, the low mass of the guideway slab produces an unfavorable mass-spring system that can only bring about an insufficient oscillation damping.
