A straight line, parallel to the axis of rotation, passes through, in sequence, the output flange, the first washer, and the hub.

A torque converter assembly is disclosed herein. The torque converter assembly includes a thrust washer having a radially inner surface configured to engage against a drive shaft. A first axial surface of the thrust washer is configured to contact a cover. A second axial surface of the thrust washer is configured to contact a damper flange. The second axial surface of the thrust washer partially defines a first flow path. The thrust washer further comprises a second flow path configured to direct fluid in a first direction and a third flow path configured to direct fluid in a second direction. The thrust washer disclosed herein both provides an axial thrust bearing feature, and also provides three distinct flow paths or passages.

A torque converter includes a front cover arranged to receive a torque and a lock-up clutch engaged with the front cover. The torque converter further includes a damper assembly engageable with the lock-up clutch. The damper assembly includes an inner spring assembly, an outer spring assembly arranged radially outside of the inner spring assembly, and a lower cover plate supporting the inner spring assembly. The lower cover plat includes a chamfer configured to retain the outer spring assembly in a spring window.

A torque converter, including: a cover arranged to receive torque; an impeller; a turbine; a stator; and a lock-up clutch including a piston plate, a first plate, a second plate axially disposed between the cover and the first plate, and a rivet non-rotatably connecting the first plate to the second plate, the rivet being a component distinct from the first plate and the second plate. The cover and the piston plate define at least a portion of a first pressure chamber. The first plate and the second plate define at least a portion of a second pressure chamber. The first pressure chamber and the second pressure chamber are arranged to receive and expel a fluid to axially displace the piston plate to open and close the lock-up clutch.

A torsional vibration damper, including: an output flange supported for rotation around an axis of rotation and including a first drive surface and a second drive surface; an intermediate flange including a first drive tab aligned in series with the first drive surface in a circumferential direction around the axis of rotation and a second drive tab aligned in series with the second drive surface in the circumferential direction; a first spring including a first end directly engaged with the first drive surface and a second end directly engaged with the first drive tab; and a second spring including a first end directly engaged with the second drive tab and a second end directly engaged with the second drive surface. In an example embodiment, the intermediate flange includes a centering tab in contact with the output flange and arranged to center the intermediate flange with respect to the output flange.

A vibration damping apparatus including a support member rotatable together with a rotational element, a restoration force generating member coupled to the support member to transmit and receive a torque with the support member, an inertial mass coupled to the support member via the restoration force generating member, a first guide surface on the restoration force generating member, a second guide surface on the inertial mass, and a coupling member having first and second rolling portions. The first and second guide surfaces are formed so that the first rolling portion rolls along the first guide surface and the second rolling portion rolls along the second guide surface along with rotation of the support member causing the restoration force generating member to swing about a rotation center of the rotational element along a radial direction of the support member and causing the inertial mass to swing about the rotation center.

An engine damper includes a drive disc having a plurality of studs circumferentially arranged to be received in a flex plate and a driven disc connected to the drive disc by a resilient member. The driven disc defines a plurality of circumferentially arranged first holes arranged in a first pattern. A hub is configured to non-rotatably connect to a shaft. The hub defines a plurality of second holes circumferentially arranged in a second pattern that corresponds to the first pattern. Connectors are disposed in the first and second holes to connect the hub to the driven disc.

A torque damper apparatus includes an input-side plate having a pair of side plates and rotatably driven in response to drive force from a motor, a center plate coupled to an output shaft and arranged between the pair of side plates, and an elastic transmission body provided between the input-side plate and the center plate to transmit rotary drive force of the input-side plate to the center plate. The input-side plate has, at a plate surface of at least one side plate, multiple weight attachment holes for attaching a balance weight. Each weight attachment hole is formed in a long hole shape extending along a circumferential direction at an outer edge portion of the side plate.

A torque transmitting device for transmitting torque between a first drive element and an output element, having a torque transmitting unit with a housing delimiting a first fluid chamber filled with a liquid, and a separating clutch arranged outside of the torque transmitting unit and the first fluid chamber in a second fluid chamber separated from the first chamber and which selectively transmits torque between the first drive element and the torque transmitting unit. The separating clutch has a clutch output that is connectable to a clutch input via a friction device and a clutch actuator that comprises a pressing element and an actuation element to which fluid pressure can be applied to move the actuation element. The pressing element is arranged within the second fluid chamber, and the actuation element is at least partly arranged within the first fluid chamber so that pressure is applied thereto by fluid pressure.

A hydrodynamic torque converter is provided with a converter housing and a converter torus with a pump impeller, a turbine wheel which is driven hydrodynamically by the pump impeller by a converter fluid. In order to bridge the hydrodynamic drive, a converter lock-up clutch which is connected between the pump impeller and the turbine wheel by pressure loading of the converter fluid is arranged radially between an outer circumference of the converter housing and the converter torus. In order to provide the converter lock-up clutch with an increased transmission capacity, the turbine wheel is assigned at least one friction disc which can be prestressed axially between a pressure-loaded annular piston, which is hooked in an axially movable manner into the converter housing, and a mating friction surface of a converter housing section radially outside the converter torus.
