Title: METHOD AND SYSTEM FOR SUPPLYING COMPRESSED AIR TO A VEHICLE AS REQUIRED, MORE PARTICULARLY A RAIL VEHICLE
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 vehicle for 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 auxiliary units 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).
