摘要： The rotary housing of a hydrokinetic torque converter, which can be utilized in the power train of a motor vehicle--for example, in conjunction with a continuously variable transmission--contains a torque monitoring device which is installed in such a way that it does not take up any, or any appreciable, additional space, especially in the axial direction of the housing. The torque monitoring device can serve to transmit torque between the lockup clutch and the output element of the torque converter. Additional features reside in the provision, configuration and manner of mounting of an auxiliary mass, and in the provision of a device for centering the piston of the lockup clutch in the housing as well as a device for centering the housing on the output element of a prime mover.

摘要： A torque converter including an axis of rotation and a flange rotatable about the axis of rotation is disclosed. The torque converter includes a turbine shell independently rotatable about the axis of rotation relative to the flange. A first plate, disposed between the flange and the turbine shell, may be fixed to the turbine shell. A second plate, disposed between the flange and the turbine shell, may be radially outward relative to the first plate. The torque converter further includes a cover having an inner surface and a third plate disposed between the flange and the cover. The first plate may include at least one ramp protruding in an axial direction toward the flange, wherein the ramp is rotatably engageable with the flange for urging the flange axially in a direction toward the cover, and for transmitting an axial force for urging a clutch to engage.

摘要： A tuned damper for a torque converter includes a piston plate with a pivot ring, an inertia ring at least partially rotatable in a circumferential direction relative to the piston plate, and a resilient element fixed to the inertia ring and frictionally engaged with the piston plate pivot ring. In some example embodiments, the pivot ring includes a pair of radially extending tabs, the resilient element includes a radially-extending leaf spring fixed to a slide roll, and an outer circumference of the slide roll is clamped by the pivot ring tabs. In an example embodiment, the pivot ring tabs each include respective distal bent segments extending toward one another to limit radial displacement of the slide roll. In an example embodiment, an inertia of the inertia ring and a torsional spring rate of the resilient element are selected so that a natural frequency of the inertia ring is less than a shudder frequency.

摘要： A hydrokinetic torque converter in the power train between the engine and the wheels of a motor vehicle has a rotary engine-driven housing which is of one piece with a pump and contains a rotary turbine having a hub which drives the input shaft of a transmission. A lockup clutch can be engaged, either entirely or with slip, to transmit torque from the housing or from the pump to the hub of the turbine. Such clutch can employ flat or conical friction linings and/or friction surfaces, for example, a friction lining on the shell of the turbine and a friction surface on a wall of the housing. The shell of the turbine in the torque converter employing such clutch is movable axially to advance the friction lining into or from engagement with the friction surface. Alternatively, the lockup clutch can be installed in a torus which is defined by the turbine and the pump of the torque converter, and such clutch can be cooled by one or more streams of a hydraulic fluid.
