A drive device includes a fluid coupling and a rotary electrical machine. The fluid coupling is configured such that a torque is inputted thereto from a first side in an axial direction and is outputted therefrom to a second side in the axial direction. The rotary electrical machine includes a first stator and a rotor. The first stator is disposed in a non-rotatable manner. The rotor is disposed to be rotated about a rotational axis of the fluid coupling. The rotary electrical machine is disposed on the second side with respect to the fluid coupling in the axial direction. The rotary electrical machine overlaps the fluid coupling in an axial view.

A drive device includes a fluid coupling, a rotary electrical machine, and a damper device. The fluid coupling includes an input unit and an output unit. The input unit includes an impeller. The output unit includes a turbine. The rotary electrical machine includes a first stator and a rotor. The first stator is disposed in a non-rotatable manner. The rotor is attached to the output unit. The damper device is disposed axially adjacent to the fluid coupling. The damper device is connected to the input unit.

A torque converter includes a torque converter body and a rotary electrical machine. The torque converter body includes a cover, an impeller, a turbine, and a first stator. The rotary electrical machine includes a rotor and a second stator. The rotary electrical machine is disposed inside the torque converter body.

The present device includes an inertia ring, a plurality of centrifugal elements, a plurality of cam mechanisms and a plurality of restriction mechanisms. The inertia ring is disposed to be rotatable with a hub flange and be rotatable relatively to the hub flange. Each centrifugal element is disposed to receive a centrifugal force generated by rotation of the hub flange and the inertia ring. When a relative displacement is produced between the hub flange and the inertia ring in a rotational direction while the centrifugal force is acting on each centrifugal element, each cam mechanism converts the centrifugal force into a circumferential force directed to reduce the relative displacement. Each restriction mechanism allows actuation of each centrifugal element by each cam mechanism, and restricts radial movement of each centrifugal element.

A lock-up device for a torque converter is disclosed. The lock-up device includes a clutch part, first and second rotary members, a plurality of elastic members and a stopper mechanism. The clutch part is provided between a front cover and a turbine, and transmits the torque inputted to the front cover to the turbine. The first rotary member is disposed between the clutch part and the turbine. The second rotary member is rotatable relative to the first rotary member. The elastic members elastically couple an outer peripheral part of the first rotary member and an outer peripheral part of the second rotary member in a rotational direction. The stopper mechanism is disposed axially between the elastic members and an outer peripheral part of a turbine shell. The stopper mechanism includes an engaging portion restricting an angular range of relative rotation between the first rotary member and the second rotary member.

Intermediate plate apparatus and related damper assemblies for use with vehicles are disclosed. A disclosed vehicle torque converter includes a clutch and a torsional vibration damper configured to receive a torque from the clutch when the clutch is engaged and dampen a torsional vibration in the torque. The torsional vibration damper includes a driven plate, a retainer plate, a first spring member, a second spring member, and an intermediate plate positioned radially outward relative to the driven plate and the retainer plate. The intermediate plate includes a body that defines an annular cavity though which the first and second spring members extend. The body is configured to engage inner and outer radial portions of the respective first and second spring members to maintain bend radii of the respective first and second spring members.

A turbine assembly includes a turbine shell, turbine hub, and a thrust washer. The turbine hub is coupled to the turbine shell via a fastener. The thrust washer is disposed on the turbine hub and includes at least one tab configured to contact the fastener. The fastener axially and radially retains the thrust washer on the turbine hub.

A hydrokinetic torque coupling device for coupling together driving and driven shafts, comprises a casing, impeller and turbine wheels, a torsional vibration damper, a turbine hub non-rotatably connected to the turbine wheel, and first and second vibration absorbers. Each of the first and second vibration absorbers is one of a dynamic absorber and a pendulum oscillator. The turbine hub is non-rotatably coupled to a driven member of the torsional vibration damper. The first vibration absorber is mounted to the turbine hub and the second vibration absorber is mounted to one of the turbine hub and the casing. The first vibration absorber and the second vibration absorber are tuned to address different orders of vibrations. The dynamic absorber includes an inertial member and a connecting plate coupled to the inertial member. The pendulum oscillator includes a support member and flyweights configured to oscillate relative to the support member.

A launch device coupling the rotary output of a prime mover to the rotary input of an automotive transmission. The launch device includes a shell defining a chamber into which impeller blades extend. A rotatable turbine is located in the chamber. Turbine blades oppose the impeller blades and receive fluid from the impeller blades, causing rotation of the turbine and an output hub. Pull bearings constructively support the shell for relative rotation with respect to one or more internal components of the launch device, such as the output hub. Portions of the pull bearings are fixed relative to an associated one of the internal components to limit axial movement of the inner and outer races of the pull bearing and, thereby, limit axial expansion of the shell.

A torque converter includes a front cover, an impeller having an outer shell non-rotatably connected to the front cover, and a turbine. A lock-up clutch is disposed axially between the front cover and the turbine. The lock-up clutch includes a piston axially displaceable and having a first opening extending from a first axial side facing the front cover to a second axial side facing the turbine. A seal ring is fixed to the front cover and sealed to the piston. A first fluid chamber is formed at least in part by the piston and the turbine, and a second fluid chamber is formed at least in part by the front cover, the seal ring, and the piston. A valve is connected to the piston and is configured to seal the first opening in response to a pressure difference in the first and second fluid chambers.
