    摘要: A magnetorheological fluid clutch has a pair of radially spaced magnetic core members that cooperate with an input rotor to form a pair of working gaps filled with magnetorheological fluid (MRF). An encapsulated electric coil disposed in a radially inner of the two magnetic cores is energized to establish a magnetic field through the cores, the input rotor and the MRF to establish a torque transmitting relation therebetween. The magnetic cores are secured to a channel ring and a housing in both of which a plurality of cooling channels are formed. The channels in the housing are in fluid communication with an input path to a serpentine flow path formed between the radially outer magnetic core and the housing to direct liquid cooling flow thereto. A return path from the serpentine flow path is in communication with the channels in the channel ring to direct liquid cooling flow therefrom. Further cooling passages are formed in the housing, channel ring, and radially inner magnetic core to direct liquid cooling through an annular chamber containing the encapsulated electric coil. The liquid cooling flow from the annular chamber and the channels in the channel ring are commingled and returned to a reservoir.

    摘要: A powertrain has an engine-driven power transmission that selectively provides six forward speed ratios, a neutral condition and a reverse speed ratio. The power transmission includes two simple planetary gear sets that are continuously interconnected between two members and selectively interconnected between two other members through a selectively engageable rotating torque-transmitting mechanism. The ring gear member of one of the planetary gear sets is continually connected with an output shaft. Three selectively engageable rotating torque-transmitting mechanisms connect a member of each planetary gear set as well as the interconnected members with an input shaft. Two selectively engageable stationary torque-transmitting mechanisms inhibit the rotation of two members of one of the planetary gear and one member of the other planetary gear set when the selectively engageable interconnection is active.

    摘要: A planetary gearing arrangement has a compound planetary gear set and a simple planetary gear set. The planetary gear sets are continuously interconnected at the sun gear members and are interconnectable through the selective engagement of two proportioning clutches which change the interaction of the gear sets. A single member, a ring gear, is continuously connected to an output shaft. The arrangement also includes two input clutches and two brakes which in combination with the proportioning clutches permit the establishment of five forward ratios and one reverse ratio. Two of the forward ratios are underdrives and two of the ratios are overdrives. All of the forward ratio interchanges, the neutral to forward ratio change and the neutral to reverse ratio change are of the single transition type.

    摘要: A selectively engageable torque transmitting mechanism has an apply piston, a plurality of first friction plates, a plurality of second friction plates, and a backing plate. The first friction plates are drivingly connected with one transmission member and the second friction plates are drivingly connected with another transmission member and alternately spaced with the first friction members. The friction plates are generally annular members having axial faces that are magnetized with opposite polarities. The magnetized faces of the first friction plates are disposed adjacent like polarity faces of the second friction plates to enforce separation thereof when the torque transmitting mechanism is in a disengaged state. The apply piston of the torque transmitting mechanism also has an annular face with a magnetic polarity disposed in opposition to an oppositely polarized surface on an adjacent member of the torque transmitting mechanism.

    摘要: A viscous clutch of the magnetorheological fluid type includes an input drive member and an output driven member. A selectively energizable magnetorheological fluid is disposed in a working gap between one cylindrical member on the input member and two cylindrical members on the output shaft. A slip ring configuration on the output member is provided to permit the introduction of electrical energy to a coil assembly disposed on the output member, which coil is energized to establish a magnetic field in the working gap, thereby energizing the magnetorheological fluid. Wiper structures on the input and output members prevent the accumulation and/or centrifugal packing of the iron particles in the magnetorheological fluid adjacent the axial ends of the cylindrical members. A cavity for excess magnetorheological fluid or fluid draining from the working gap is provided between opposed members of the output member. One of the opposed members has an angular wall portion diverging toward the working gap to direct fluid into the working gap when the output member is rotating. The input member includes a finned hub portion rotatably disposed in the cavity to assist in heat transfer from the magnetorheological fluid during clutch operation. A bearing member isolated from the cavity supports the output member on the input member.
