A secondary assembly drive of an internal combustion engine and a method for operating same are provided. The secondary assembly drive includes: a first drive wheel () which can be rotatably connected to a crank shaft (CR) of the internal combustion engine, an electric machine which can be operated either as a generator (AL) of as a motor (M) and a second drive wheel () which can be rotatably connected to the electric machine (AL, M), an air-conditioning compressor (A/C) and a third drive wheel () which can be rotatably connected to the air-conditioning compressor, a traction element () which rotates infinitely and which wraps around the drive wheels, and an actuable clutch () for disconnecting the drive of the electric machine and of the air-conditioning compressor from the crankshaft when necessary. In addition, the air-conditioning compressor is designed for operation in both rotational directions, and a reversal of the rotational direction between the generator operating mode and the motor operating mode of the electric machine is provided.

Secondary assembly drive of an internal combustion engine and method for operating same

A generator drive system for the generator () of an internal combustion engine (), including a flexible drive having a traction mechanism () which is guided across a generator pulley () driving the generator (). The generator () is configured and electrically wired such that the generator () can be temporarily driven as a motor, and the generator () is coupled to the generator pulley () or the crankshaft pulley () is coupled to the crankshaft () via an overrunning clutch () which allows the generator (), when operated as a motor, running faster than the generator pulley () or, taking into consideration a gear ratio, the crankshaft ().
