摘要： A hydrokinetic torque coupling device includes an impeller, a casing having a first engagement surface, a damper assembly, a turbine-piston and a drive-clutch component non-moveably attached to the turbine-piston and having a second engagement surface. The turbine-piston is axially displaceable relative to the casing to move the second engagement surface axially towards and away from the first engagement surface for positioning the hydrokinetic torque coupling device respectively into and out of a lockup mode in which the first and second engagement surfaces frictionally interlock with one another to mechanically lock the casing non-rotatably relative to the input part of the damper assembly. The drive-clutch component is configured to engage and rotationally drive a torsional vibration damper.

摘要： A torque converter, including: a cover; an impeller shell; a turbine shell; a turbine clutch formed by the turbine and impeller shells; and a stator formed of a single piece of material and including a protrusion extending in an axial direction and having a radial surface. In a drive mode : the cover transmits torque to the impeller shell; the turbine clutch is open; the radial surface forms an entirety of a portion of the stator closest, in the axial direction from the stator toward the turbine shell, to the turbine shell; and the radial surface is free of contact with the turbine shell. In a coast mode for the torque converter, at least a portion of the radial surface is in contact with the turbine shell or is separated from the turbine shell by a layer of fluid in contact with the radial surface and the turbine shell.

摘要： A hydrokinetic coupling device includes a lock-up clutch having at least one friction disc mounted such that it can slide axially with respect to a first rotary shaft, at least one first backing disc rotating as one with a secondary rotary shaft and a support ring to support the backing disc. The support ring has at least one axial groove circumferentially delineated by an upstream face and by a downstream face. A radial guide tooth of each backing disc is housed such that it can slide axially in the groove. Elastic preload elements are provided which are able to exert a preload torque to clamp the guide tooth of each braking disc circumferentially against one of either the upstream or downstream faces of the guide groove.

The lock-up clutch includes a front cover, a lock-up piston, a plurality of torque transmitting plates, and a plurality of friction materials formed on the torque transmitting plates and having three or more friction surfaces. The friction materials are constituted by a first friction material frictionally contactable with the front cover, a second friction material frictionally contactable with the lock-up piston, and third friction materials frictionally contactable with at least one of the plates. Three or more friction surfaces are constituted by outside friction surfaces formed on the first and second friction materials and each having a small area, and inside friction surfaces formed on the third friction materials and each having a large area.
