Abstract
A hydrokinetic torque-coupling device for coupling driving and driven shafts. The torque-coupling device includes a casing, an impeller wheel and a turbine wheel hydrodynamically drivable by the impeller wheel, and a lock-up clutch. The lock-up clutch includes a lockup piston axially movable toward and away from the casing, a first disc carrier non-movably secured to the casing, a second disc carrier radially offset from the first disc carrier and drivingly coupled to the turbine wheel, at least one drive disc non-rotatably and axially movably mounted to the first disc carrier, at least one driven disc non-rotatably and axially movably mounted to the second disc carrier and disposed adjacent to the at least one drive disc so as to define a clutch pack, and a clutch biasing spring disposed between the casing and the clutch pack so as to bias the clutch pack toward the lockup piston.
