Abstract
A driving assembly includes a viscous shear coupling (15), a clutch (17) and a hysteresis or eddy current brake (19). The clutch comprises inner and outer parts (20 and 21) between which are received torque-transmitting balls (18) received in a cage (16) to which is connected a disc (30) forming part of the brake. The outer part (21) can overrun the inner part whether or not the brake is actuated. The inner part (20) can overrun the outer part (21) if the brake (19) is not actuated but drives the outer part (21) if the brake is actuated. The outer part (21) is connected to one part of the viscous shear coupling (15). A drive member (34) is connected to the inner clutch part (20) and a driven member (38) forms the other part of the viscous shear coupling.
