Abstract
A clutch device for a clutch system has an input member that rotates at a first speed. A friction medium is disposed between the input member and an output member. The output member rotates on a bearing coupled to a piston. The piston translates relative to the input member, between an engaged position in which the friction ring frictionally engages with the input member, thereby driving the output member to rotate at the first speed, and a disengaged position in which the friction ring is spaced apart from the input member. A biasing member urges the piston toward the engaged position. A pressurized fluid in a fluid receiving chamber selectively urges the piston toward the disengaged position. A resistance member disposed in a chamber containing a viscous fluid transfers torque from the input member to rotate the output member at a second speed.
