Abstract:
1. Ancillary drive of an internal combustion engine, comprising: a first drive wheel that is adapted to be rotationally connected to a crankshaft (CR) of the internal combustion engine, an electric machine that is operable selectively as a generator (AL) or as a motor (M) and a second drive wheel ( an air-conditioning system compressor (A/C) and a third drive wheel that is rotationally connected to the air-conditioning system compressor, an endlessly rotating traction mechanism that wraps around the drive wheels, and a controllable coupling for drive disconnection of the electric machine (AL, M) and the air-conditioning system compressor (A/C) from the crankshaft (CR) when necessary, the air-conditioning system compressor (A/C) is formed for compressor operation in both rotational directions and a reversal of the rotational direction is provided between a generator mode and a motor mode of the electric machine (AL, M).
