ABSTRACT OF THE DISCLOSURE A clutch drive mechanism (10) interconnects a vehicle engine (12) with a vehicle air compressor (14) to provide a driving connection therebetween when operation of the air compressor (14) is necessary to charge the vehicle reservoir (18) and to break the driving connection to the air compressor (14) when the reservoir (18) is fully charged. The drive mechanism (10) includes a clutch disc pack (82) which is controlled by a piston (52). Piston (52) responds to a pressure signal from a conventional unloader mechanism (20) to disengage the clutch mechanism (10) to disconnect the air compressor (14) from driving connection with the vehicle engine (12). A thrust bearing (68) provides a rotary connection between the piston (52) and the disc pack (82) and another thrust bearing (46) is provided between the output drive (36) and the clutch drive housing (26) so that axial forces or loads are transmitted to the housing (26) instead of to the compressor (14). These bearings rotate only when the clutch driven mechanism is engaged.
