MAGNETORHEOLOGICAL FAN COUPLING

摘要

A magnetorheological fan coupling ( 10 ) having an inverted construction with an input member ( 18 ) rotatably mounted to an output member ( 20 ). The input member ( 18 ) defines a fluid chamber ( 50 ) with the output member ( 20 ) rotating therein and a magnetic medium ( 52 ) between the output member ( 20 ) and the input member ( 18 ). The coupling ( 10 ) further includes an electromagnet subassembly ( 14 ) actuated by a controller ( 82 ) for adjusting the shear stress of the magnetic medium ( 52 ) and regulating the amount of torque transferred from the input member ( 18 ) to the output member ( 20 ).
