ABSTRACT:
A drive system for driving an engine auxiliary equipment has a first power transfer device for transferring an output torque of the crankshaft to an interim shaft at all time and a second power transfer device comprising a crank pulley mounted for relative rotation on the crankshaft, an interim pulley mounted for relative rotation on the interim shaft and an input pulley related to the auxiliary equipment all of which pulleys are operationally coupled by a belt so as to transfer an output torque of the crankshaft to the auxiliary equipment. A first clutch is disposed between the crankshaft and crank pulley so as to connect and disconnect a transfer of power between the crankshaft and crank pulley. A second clutch is disposed between the interim shaft and interim pulley so as to connect and disconnect a transfer of power between the interim shaft and interim pulley. The first and second clutches are actuated to create a first transfer path or a second transfer path which are different in ratio of power transfer.
