A torque converter a cover arranged to receive torque for rotation about an axis; an impeller non-rotatably connected to the cover; a lock-up clutch including a piston; a turbine that includes a turbine shell and a turbine hub, the turbine hub comprising: a first plate to which the turbine shell is non-rotatably connected; a second plate axially adjacent to the first plate and non-rotatably connected thereto, the second plate defining a plurality of apertures that are circumferentially offset from each other; and a third plate non-rotatably connected to the second plate and positioned axially adjacent thereto, such that the second plate is positioned axially between the first and third plates, the third plate defining a plurality of ports that are circumferentially offset from each other and are aligned with the corresponding plurality of apertures defined by the second plate.

Turbine hub of a torque converter

A torque converter includes a front cover arranged to receive a torque; an impeller non-rotatably connected to the front cover; a turbine in fluid communication with the impeller; a lock-up clutch having a piston and a seal plate disposed axially between the piston and the turbine. The torque converter further includes a flow plate non-rotatably connected to the front cover, and a backing plate sealed to the piston and disposed axially between the flow plate and the seal plate. A through-bore extends axially through the backing plate and the flow plate. The flow plate is welded to the backing plate around the through-bore. A first chamber is bounded at least in part by the piston, the seal plate, and the backing plate, and a second chamber is bounded at least in part by the front cover, the piston, the backing plate, and the flow plate.

Torque converter having multiple flow passages

A torque converter includes a case and a bypass clutch having a plate rotationally fixed to the case and a friction disk having a friction material configured to engage with the plate to rotationally couple the friction disk to the plate when the bypass clutch is engaged. The friction disk includes a first circumferential connection surface having a plurality of alternating convex and concave arcuate segments. A drive plate includes a second circumferential connection surface having a plurality of alternating convex and concave arcuate segments. The first and second connection surfaces are in meshing engagement with the convex segments of the friction disk meshing with the concave segments of the drive plate and with the concave segments of the friction disk meshing with the convex segments of the drive plate.
