  • Hydrokinetic torque coupling device with centered lock-up clutch
    Patent number: 11143280
    Abstract: A hydrokinetic torque-coupling device includes an impeller wheel, a turbine wheel, a stator, a casing, a stationary shaft operatively coupled to the stator so that a driven shaft axially extends through the stationary shaft, a first fluid passage formed axially through the driven shaft, a second fluid passage formed between the stationary shaft and the driven shaft, a third fluid passage formed radially adjacent to the stationary shaft, and a lock-up clutch including a piston housing member non-moveably attached to a center hub of the casing, and a lockup piston mounted to the center hub so as to be axially movable along the center hub. The first fluid passage hydraulically connected to a first hydraulic chamber. The second fluid passage hydraulically connected to a second hydraulic chamber. The third fluid passage hydraulically connected to a torus chamber defined between the impeller shell and the turbine shell.
