Abstract
A drive arrangement for auxiliary aggregates of an internal combustion engine, especially for motor vehicles is constructed as a two-speed drive, that is at operation of the internal combustion engine at low speeds the auxiliary aggregates are driven from the drive shaft of the engine, whereas at operation of the internal combustion engine at high speeds the auxiliary aggregates are driven from the cam shaft of the engine over an intermediate pulley provided with a free wheel clutch. During low speed of the engine the auxiliary aggregates are driven from a pulley freely rotatably mounted on the drive shaft of the engine but connectable thereto by a centrifugal clutch, which at high speed of the drive shaft disconnects the drive of the pulley by the drive shaft of the engine while the free wheel clutch engages. The auxiliary aggregates, respectively the pulleys thereof, are located in one plane with the pulley on the drive shaft and the intermediate pulley. This provides for a space-saving arrangement and a drive with relatively few parts.
