Problems solved by technology

[0003] The disadvantage of this configuration must be seen: the still functioning load-carrying magnets are operated at a current much higher than the nominal current during the period of such a failure in order to maintain the predetermined support gap
Although it is conceivable to vent a pneumatic spring affected by such a failure, this has the consequence that no load may be transferred from it to the appropriate pair of carrying magnets

Embodiment Construction

[0012] figure 1 schematically represents a cross-section through a magnetically levitated vehicle 31 conventionally movably mounted on a guide rail extending in the longitudinal direction of the route, said guide rail comprising a support 32 made of steel and / or concrete and The guide rail plate 33 that is installed on it. The propulsion of the magnetically levitated vehicle 31 is achieved, for example, by a long stator motor comprising stator laminations 34 attached below said rail plate 33 and arranged continuously in its longitudinal direction. The stator laminations 34 have an alternating succession of teeth and slots (not shown here) into which windings supplied with three-phase current of variable amplitude and frequency are inserted. The actual excitation field of the long stator motor is generated by at least one first magnet arrangement acting as a carrier magnet 35 attached to said magnetically levitated vehicle 31 by at least one transverse bracket 36 and having a ...

Abstract

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).

Description

technical field [0001] The invention relates to a magnetic levitation vehicle including a pneumatic spring control system. Background technique [0002] Known maglev vehicles of this type comprise a cradle extending in its longitudinal direction, which is connected on the one hand to carrying (supporting) magnets enabling magnetic levitation and on the other hand supports the actual vehicle including the passenger unit via pneumatic springs body. Thus, the pneumatic spring operates at a preselected nominal air pressure of eg 8 bar and is coupled to a pneumatic spring control in the form of a level control for controlling the air pressure during operation to prevent lateral tilting of the vehicle. For reasons of redundancy, it is common practice to provide hangers at those locations where the gas springs are mounted, with two adjacent points of support, each of which is formed by a suitable frame section, with which the Each of the hangers is supported on a separate carryin...
