Method and device for a demand-based compressed air supply of a vehicle, in particular a rail vehicle

摘要

The invention relates to a method and a device for an on-demand compressed air supply of a vehicle, in particular a rail vehicle, being covered by a with a main tank air line (2) main air compressor (1) at least the main air demand of the rail vehicle for operating a pneumatic brake system (3), and wherein by at least one electric motor-operated auxiliary air compressor (8) with the other hand, less compressed air additional power for the operation of ancillaries is generated, during the shutdown operation of the vehicle only the at least one auxiliary air compressor (8) is used to generate compressed air when needed, with the held by pneumatic actuator (9) pantograph (5) during the shutdown operation in permanent contact with an electrical supply line (6).
