Drivetrain and method for providing a supply to a compressed air system

Abstract

The invention relates to a drivetrain, in particular motor vehicle drivetrain, with a combustion engine having a drive output shaft and which produces a hot exhaust-gas flow; with a turbocompound system comprising: an exhaust-gas turbine which is arranged in the exhaust-gas flow such that it can be impinged upon by exhaust gas and which converts exhaust-gas energy into propulsive energy, wherein the exhaust-gas turbine is drive-connected, or can be switched so as to be drive-connected, to the output shaft of the internal combustion engine and also drives a turbocompressor or positive-displacement compressor by means of which the internal combustion engine is charged on the fresh-air side; with a compressed air system, comprising: an air compressor which can be driven by means of the combustion engine or an additional motor and which feeds compressed air into at least one compressed-air circuit or a compressed-air line. The invention is characterised by the fact that the air compressor can be charged by means of the turbocompressor or positive-displacement compressor of the turbocompound system, wherein air compressed by the turbocompressor or positive-displacement compressor is supplied to the air compressor on its intake side.
