Abstract
A viscous clutch (30; 30′) includes a stationary journal bracket (32; 32′) defining a mounting shaft (32-1; 32-1′), an output member (34; 34′) rotatably supported on the mounting shaft about an axis (A), an input member (34; 34′) rotatably supported on the mounting shaft about the axis, and a working chamber (50; 50′) defined between the input member and the output member to selectively transmit torque there between when a shear fluid is present. The mounting shaft extends axially through the viscous clutch from a front face (62; 62′) of the viscous clutch to a rear face (56; 56′) of the viscous clutch, with the rear face defining a mounting surface for mounting the viscous clutch at a mounting location. The front and rear faces are located at opposite sides of the viscous clutch and face in opposite directions.
