Abstract: Presented are torque converters (TC) with planetary-type vibration dampers, methods for making/using such TC assemblies, and vehicles equipped with such TC assemblies. A TC assembly includes a TC housing drivingly connected to a prime mover to receive torque therefrom, and a TC output member drivingly connected to a transmission to transfer torque thereto. Rotatably mounted within an internal fluid chamber of the TC housing are juxtaposed turbine and impeller blades. The impeller blades are rotatably mounted to the housing. A TC clutch is operable to lock the TC housing to the TC output member. A torsional vibration damper, which is disposed within the internal fluid chamber, includes a sun gear attached to the TC output member for unitary rotation, a ring gear attached to the TC clutch for unitary rotation, and a planet carrier intermeshed with the ring and sun gears and attached to the turbine blades for unitary rotation.

Abstract: A torque converter for a vehicle includes an annular housing. A turbine member is fluidically connected to the pump member. A lock-up clutch is selectively engaged between the annular housing and the turbine member. A lock-up clutch actuator is connected to the lock-up clutch. A cavity is defined between the annular housing and the turbine member. A first fluid circuit is fluidically connected to the pump member, the cavity and a first side of the lockup clutch actuator. The first fluid circuit delivers a fluid to engage the lock-up clutch actuator. A second fluid circuit is hydraulically connected to the pump member and the cavity. The second fluid circuit guide the fluid from the annular housing. A third fluid circuit is hydraulically connected to a second side of the lock-up clutch actuator. The third fluid circuit selectively delivers a pressurized fluid to release the lock-up clutch.

Abstract: A system for absorbing vibration and transmitting torque from a rotating power source to a rotatable load includes a rotatable driving member configured as an input to be driven by the power source to rotate about an axis of rotation. The system has a cam plate with a cam surface. A spring is configured to extend lengthwise in a radial direction relative to the axis of rotation. The spring is configured to be compressed due to the cam surface during relative rotation of the driving member and a driven member when the cam plate is operatively connected to rotate in unison with said one of the driving member and the driven member. The spring therefore has an effective spring rate dependent upon the cam surface, compression of the spring absorbs torsional vibration of the driving member, and the cam plate.

Abstract: A damper system includes a turbine shaft rotatably connected to a torque converter having a clutch. A hydraulically actuated clutch is coupled to the turbine shaft. A first spring cage has a first cage portion connected to the hydraulically actuated clutch and a second cage portion connected to a friction plate. A first spring set is connected to the first and second cage portions. Springs of the first spring set are deflected by axial rotation between the first and second cage portions when the torque converter clutch is engaged. A second spring cage has a first cage section connected to the hydraulically actuated clutch and a second cage section connected to a torque converter turbine. A second spring set has second springs having a spring constant different than the first spring set. The second spring set springs are deflected by axial rotation between the first and second cage sections.

Abstract: A radially stacked planetary gear assembly provides improved lubrication fluid flow to the planet gear bearings of an outer planetary gear set which is especially important when the housing or outer planetary gear carrier is stationary. The assembly includes radially aligned or stacked inner and outer planetary gear sets each having a sun gear, a ring gear and a carrier having planet gears in constant mesh with the sun and ring gears wherein the ring gear of the inner gear set is also the sun gear of the outer gear set and the outer carrier is the assembly housing. The sun gear is disposed on a transmission shaft having lubrication passages which aligns with pluralities of radial openings in a hub housing. A circular plate or guide adjacent one side of the housing includes channels which align with the openings and functions as a lubrication director, channeling lubrication from the transmission shaft and the pluralities of radial openings in the housing hub to the outer bearings, shafts and planet gears.
