Embodiment Construction

[0020] according to figure 1 , the device for supplying compressed air to a rail vehicle (not further shown here) comprises a main air compressor 1 for supplying a main container air line 2 extending longitudinally through the rail vehicle, The main tank air line serves to cover the main air requirement of the rail vehicle, in particular for operating the pneumatic brake system 3 . The main air compressor 1 is driven by a three-phase AC motor 4 which is connected to the power supply line 6 via a retractable pantograph 5 (shown here in the extended state) for electrical energy supply . Furthermore, by setting the electric motor 7 to a relatively small size, an additional auxiliary air compressor 8 is provided, which has a lower delivery power compared to the main air compressor 1, in order to additionally generate energy for operating the auxiliary units. compressed air. A pneumatic servo drive 9 for supplying the pressure supply is also connected to the main container air l...

Abstract

The invention relates to a method and a system for supplying compressed air to a vehicle as required, more particularly a rail vehicle, wherein at least the primary air requirement of the rail vehiclefor operating a pneumatic braking system (3) is covered by a primary air compressor (1) that is connected to a primary tank air line (2) and wherein additional compressed air for operating auxiliaryunits is generated by at least one electromotive auxiliary air compressor (8) having a lower delivery output than the primary air compressor. When the vehicle is parked, only the at least one auxiliary air compressor (8) is used to generate compressed air as required, said air being used, whilst the vehicle is parked, to maintain permanent contact between a current collector (5) that is actuated by a pneumatic actuating drive (9) and an electric supply line (6).

Description

technical field [0001] The invention relates to a method for the on-demand supply of compressed air to a vehicle, in particular a rail vehicle, wherein a main air compressor connected to a main container air line covers at least The primary air requirement of the power system, wherein additional compressed air is generated for the operation of the auxiliary units by means of at least one electrically operated auxiliary air compressor which has a comparatively low delivery capacity. Furthermore, the invention also relates to a device capable of implementing such a method and a computer program product embodying said method. Background technique [0002] The field of application of the invention extends primarily to rail vehicles, primarily electrically operated rail vehicles, which receive the electrical energy required for operation from electrical overhead lines via pantographs. In addition to the first energy source in the high-voltage range, the vehicle concerned here al...
