1. A drive train of a motor vehicle, said drive train comprising: a vehicle drive shaft;a vehicle drive engine configured for driving the motor vehicle via said vehicle drive shaft driven by said vehicle drive engine;a compressor configured for being driven one of periodically and permanently and for compressing air for a compressed-air system of the motor vehicle;a plurality of compressed-air brakes of said compressed-air system, said plurality of compressed-air brakes being supplied with compressed air compressed by said compressor;at least one drive unit formed as a steam-driven expansion machine, said compressor being associated with at least one said drive unit formed as said steam-driven expansion machine by which said compressor is configured for being driven, said compressor being one of configured for being driven by and driven by way of at least one of said vehicle drive engine and an additional drive, said steam-driven expansion machine being associated with said compressor as a second drive unit with which said compressor is configured for being additionally driven. 2. The drive train according to claim 1, wherein said vehicle drive engine is a combustion engine, said additional drive being an electromotor. 3. The drive train according to claim 1, wherein at least one of said expansion machine and said compressor is arranged as a piston engine. 4. The drive train according to claim 3, wherein said piston engine is at least one of a rotary combustion engine and a reciprocating piston engine. 5. The drive train according to claim 1, wherein said expansion machine one of is in a drive connection with said vehicle drive shaft and is configured for being switched to said drive connection in order to drive the motor vehicle by way of said expansion machine. 6. The drive train according to claim 1, further comprising a steam circulation which includes a steam generator, a condenser, and a fluid pump, said expansion machine being arranged in said steam circulation, said vehicle drive engine being a combustion engine, said steam generator being supplied with one of a waste heat of said combustion engine and heat from a plurality of exhaust gases of said combustion engine. 7. The drive train according to claim 6, further comprising a burner configured for supplying said steam generator with combustion heat, said burner being driven with a fuel of said combustion engine. 8. The drive train according to claim 1, further comprising a common housing, said expansion machine and said compressor being arranged in said common housing. 9. The drive train according to claim 1, further comprising two separate housings, said expansion machine and said compressor being arranged respectively in said separate housings. 10. The drive train according to claim 1, wherein said expansion machine includes an expansion machine output shaft and said compressor includes a compressor drive shaft, said expansion machine output shaft and said compressor drive shaft being arranged separately from one another and being arranged next to one another. 11. The drive train according to claim 10, wherein said expansion machine output shaft and said compressor drive shaft are arranged next to one another at least one of in an axial direction, in alignment with each other, and one of adjacent and concentric relative to one another in a radial direction. 12. The drive train according to claim 10, further comprising a first clutch and a second clutch, wherein said vehicle drive engine is a combustion engine which includes an engine output shaft which can be switched into a drive connection with said compressor selectively via said first clutch, said drive connection being one of a purely mechanical drive connection and a hydrodynamic drive connection, said second clutch being provided in a power flow between said expansion machine output shaft and said compressor drive shaft, by way of which another drive connection can selectively be produced between said expansion machine output shaft and said compressor drive shaft, with said first clutch and said second clutch being arranged especially as a common double clutch with two power inputs and two power outputs, and one said power input and one said power output being formed by a same power interface. 13. The drive train according to claim 12, further comprising two separate housings and a drive-through mechanism, said expansion machine and said compressor being arranged respectively in said separate housings, said drive-through mechanism being provided in one of said two housings for one of said expansion machine and said compressor of said other housing. 14. The drive train according to claim 12, further comprising two separate housings and a bearing, said expansion machine and said compressor being arranged respectively in said separate housings, wherein one of said expansion machine output shaft and said compressor drive shaft is held by said bearing one of in, on, and adjacent to a respective other of said two housings and without a bearing in its own said housing. 15. The drive train according to claim 1, further comprising a steam circulation which includes a steam generator, a condenser, and a fluid pump, said expansion machine being arranged in said steam circulation, said vehicle drive engine being a combustion engine, said steam generator being supplied with one of a waste heat of said combustion engine and heat from a plurality of exhaust gases of said combustion engine, wherein heat is derived from said compressor and is supplied to said steam circulation behind said fluid pump and before said steam generator. 16. The drive train according to claim 15, further comprising a housing, wherein a medium of said steam circulation is guided in a heat-transmitting manner through a housing of said compressor. 17. The drive train according to claim 1, further including a steam circulation circuit including said steam-driven expansion machine and said compressor which is in series with said steam-driven expansion machine in said steam circulation circuit.
