    摘要： A method for reducing overheating in a clutch assembly having a clutch housing, a shaft, and a clutch pack. The clutch pack includes a backing plate, an applied plate, a plurality of friction plates, and a plurality of reaction plates. A primary actuator applies pressure to the applied plate to longitudinally compress the entire clutch pack and couple rotation of the clutch housing and the shaft. A secondary actuator applies pressure to at least one plate in the plurality of friction plates and the plurality of reaction plates to longitudinally move the at least one plates independently of the applied plate. This relieves some of the torque transmitted across the clutch pack adjacent the applied plate and reduces localized temperature spikes in the clutch pack adjacent to the applied plate.

    摘要： The lubricating structure includes a rotary shaft, a power transmission apparatus having a power transmission element disposed on an outer circumference of the rotary shaft and formed by alternately stacking frictional members, and a flow channel guides a lubricating liquid to the power transmission element. The power transmission element includes an inner circumferential cylindrical section rotated integrally with the rotary shaft, an outer circumferential cylindrical section rotated integrally with the frictional member, and a disk section configured to connect the inner circumferential cylindrical section and the outer circumferential cylindrical section. Inner-diameter-side through-holes through which a lubricating liquid passes on an inner diameter side of the disk section and outer-diameter-side through-holes through which a lubricating liquid passes on an outer diameter side of the disk section are formed in the disk section, and the inner-diameter-side through-holes and the outer-diameter-side through-holes are alternately disposed in a circumferential direction of the disk section.

    摘要： A torque transmitting device having a spring pack assembly, includes a first spring retainer ring abutting a hydraulically actuated piston, a second spring retainer ring abutting a piston housing, and a plurality of coiled springs biasing the first spring retainer ring apart from the second retainer ring, thereby urging the hydraulically actuated piston slideably apart from the fixed piston housing. A composite spring support ring is coaxially disposed between the first spring retainer ring and the second spring retainer ring. The spring support ring includes cylindrical walls defining cylindrical passageways configured to receive the coiled springs. Each of the cylindrical passageway includes include a diameter (d) that is sufficiently narrow such that the cylindrical wall completely surrounds the mid-portion of the coiled spring thus preventing the coiled spring from bending lengthwise, but sufficiently wide such that the coiled spring does not saw into the cylindrical walls.

    摘要： A selectable one way clutch includes a reverse strut pocket plate having a first plurality of struts or pawls, a reverse notch and forward strut pocket plate having a second plurality of struts or pawls, a selector plate disposed between the plates controlled by a selector plate actuator and a forward notch plate. The reverse notch and forward strut pocket plate includes a plurality of ratchet teeth disposed about its periphery which cooperate with a pin or pushrod of a linear actuator. When the reverse notch plate and forward strut pocket plate is stationary but the one way clutch is still carrying torque, the linear actuator may be actuated to rotate the reverse notch plate and forward strut pocket plate to unlock or release the torque carrying struts which would otherwise remain in their locked torque transmitting positions until all or substantially all torque across the clutch was removed.

    摘要： The present disclosure relates to a torque converter for vehicle. The torque converter includes a front cover, an impeller configured to rotate and being coupled to the front cover, a turbine disposed to face the impeller, a turbine shell provided in the turbine, a stator disposed between the impeller and the turbine, and a lockup clutch provided with a drive hub connected to the front cover. The lock-up clutch has a drive disc provided in the drive hub, a driven disc coaxially disposed to the drive disc, and a driven hub provided with the driven disc, and a torsional damper comprising a retaining plate disposed between the lock-up clutch and the turbine. Engine torque is transmitted to the retaining plate through the front cover by a frictional contact between the drive disc and the driven disc.
