Abstract

Disclosed is a switch arrangement for magnetically levitated railways, comprising a support (1), which is bendable transversally to the direction of travel and is provided with track or component fittings, a rail arranged transversally to the direction of travel, a rack (23) arranged transversally to the direction of travel and a supporting frame (15) for receiving said support (1). The supporting frame is supported on the rail by a running wheel (16) and comprises a drive mechanism (18) with a toothed wheel (20) that engages in the rack (23) as well as a motor for the propulsion thereof. According to the invention, the support (1), the supporting frame (15) and the drive mechanism (18) form, as an entity, a firmly connected assembly which is arranged in such a manner that it can be displaced in the direction of travel and relative to the rail (17) and the rack (23).

Claims9

Dependent claims

A switch assembly for magnetic levitation railways, including:

a girder (1), extending in a travel direction (x) and flexible transversely to it and provided with travel way or equipment parts (6, 8);
a rail (17) located transversely to the travel direction;
a rack (23) located transversely to the travel direction;
and a load-bearing frame (15), receiving the girder (1), that has a rotatably supported carrying wheel (16) braced on the rail (17) and a drive mechanism (18) with a gear wheel (20) meshing with the rack (23) and with a motor (22) intended for driving it, and the switch adjustment is effected by displacement of the load-bearing frame (15) along the rail (17) by means of the drive mechanism (18) and a thus-effected flexing of the girder (1), characterized in that the girder (1), the load-bearing frame (15), and the drive mechanism (18) form a solidly joined-together structural unit which as a whole is located displaceably in the travel direction (x) relative to the rail (17) and to the rack (23).
