Magnetic levitation vehicle comprising a pneumatic spring control system

摘要

A magnetic levitation vehicle is described, which comprises a car body (2), being mounted by means of pneumatic air springs (4) on a suspension frame (5), said suspension frame (5) being supported by means of supporting points (5b) on pairs of carrying magnets (35A, 35B). According to the invention a control device (14) is assigned to said pneumatic springs (4) in such a manner that on failure of one of the two carrying magnets (35A, 35B) the pressure in the pneumatic springs (4) can automatically be reduced to a pre-selected fraction of the nominal air pressure (FIG. 3).

1. A magnetic levitation vehicle comprising:
a car body (2), a plurality of suspension frame sections (5) arranged so that the sections, while not directly coupled with each other, form an extension frame extending in parallel to a longitudinal vehicle axis (3), wherein said extension frame sections (5) include ends comprising supporting elements (5a) and wherein each supporting element (5a) comprises two adjacent supporting points (5b) that are arranged one behind the other in a direction of the longitudinal axis (3), a number of carrying magnets (35) arranged one behind the other in the direction of said longitudinal axis (3) that act in pairs (35A, 35B) on said adjacent supporting points (5b), and at least one controllable pneumatic spring (4) arranged in the area of adjacent supporting points (5b) that operates at a pre-selected nominal air pressure, said spring (4) supporting the car body (2) on the suspension frame, wherein a control device (14) is assigned to said pneumatic spring (4) and is activated in response to a fault signal generated on failure of one of the two carrying magnets (35A, 35B) and wherein in response to said activation the control device automatically controls the pressure in the pneumatic spring (4) to be reduced to a pre-selected fraction of the nominal air pressure.
