Abstract
An electric drive module for an electrified vehicle includes an electric motor, a transmission and a multispeed actuation mechanism (MAM). The transmission is driven by a rotatable output of the electric motor and includes a first drive shaft and a second drive shaft. The transmission has a first gear set that selectively converts rotatable motion of the first drive shaft into rotatable motion of the second drive shaft in a first gear mode at a first drive ratio, and a second gear set that selectively converts rotatable motion of the first drive shaft into rotatable motion of the second drive shaft in a second gear mode at a second drive ratio, distinct from the first drive ratio. The MAM has magnetic fluid therein. Activation of the magnetic fluid causes a shift to occur within the transmission from the first gear set to the second gear set.
