ABSTRACT:
A drive system has an input shaft and an output shaft. An oil shear clutch assembly is operable to lock the input shaft to the output shaft and an oil shear brake assembly is operable to lock the output shaft to the housing of the drive system. The clutch assembly is normally engaged and the brake assembly is normally applied due to the force being exerted by a first and second plurality of coil springs. Power supplied to a first AC coil will disengage the clutch and power supplied to a second AC coil will release the brake. The drive system will therefore act as a braking system when power is terminated to the drive system.
