Abstract
A viscous clutch includes a housing, an input device rotationally fixed to the housing, a rotor, a working chamber, a reservoir, a valve, and a quick disconnect bushing. The housing has a base, a cover, and a housing hub connected in in a rotationally fixed configuration. The input device is a pulley, a sprocket, and/or a gear. The rotor has a rotor disk and a rotor hub connected in a rotationally fixed configuration, and a central opening extends entirely through the rotor hub. The reservoir is carried by the housing and overlaps the input device in an axial direction. The quick disconnect bushing is removably secured to the rotor hub at the central opening and permits a rotationally fixed engagement between the rotor and an item driven by the clutch, such as an output shaft.
