Abstract

The arrangement consists of a drive (10) for the auxiliaries of an engine e.g. a generator (12), an air conditioning compressor (13), an air pump (15) and a hydraulic pump (16). At low engine speed, a centrifugal coupling (35) connects a first set of pulleys (18, 26) to the crankshaft (17). One pulley (18) drives the transmission (27) via a belt (21). A second set of pulleys which is also mounted on the crankshaft is driven from this transmission as well as are a number of other auxiliaries. When engine speed increases, the centrifugal coupling disconnects the first two pulleys from the crankshaft and a free wheel coupling (25) connects the second set of pulleys directly to the crankshaft.
