    摘要: A normally-engaged clutch is provided having a friction-element with a first side and an opposing second side, a first plate configured for pressing against the friction-element on the first side, and a second plate configured for pressing against the friction-element on the second side. The clutch also includes a biasing device configured to apply a first force to the second plate for pressing the second plate against the friction-element to engage the clutch. Additionally, the clutch includes an apply piston for applying a second force to the first plate, and a release piston for applying a third force to the second plate. The clutch is disengaged when the second plate is pushed away from the friction-element by the third force in the absence of the second force, and is engaged when the first plate is pressed against the friction-element by the second force.

    摘要: A torque converter for an automatic transmission includes a first fluid flow path for supplying a fluid to a pump cavity, a second fluid flow path for removing the fluid from the pump cavity, and a third fluid flow path for supplying a hydraulic signal to a lock-up clutch. The third fluid flow path is separate and distinct from the first fluid flow path and the second fluid flow path. A sleeve divides a stepped axial bore in the turbine output shaft into an inner stepped axial bore cavity, which is part of the third fluid flow path, and an outer stepped axial bore cavity, which is part of the first fluid flow path. The torque converter further includes an isolator assembly having a twenty degree rotational travel dampening distance.

    摘要: A transmission is provided having a stationary member, an input member, an output member, four planetary gear sets, a plurality of coupling members and five torque transmitting devices. Each of the planetary gear sets includes first, second and third members. The five torque transmitting mechanisms are selectively engageable to interconnect one of the first, second, and third members with another of the first, second, third members, and a stationary element. The torque transmitting mechanisms are selectively engageable in combinations of at least three to establish at least eight forward speed ratios and at least one reverse speed ratio between the input member and the output member. A first of the five torque-transmitting mechanisms is a selectable one-way clutch engageable to interconnect the third member of the fourth planetary gear set with the stationary member.

    摘要: A multi-speed transmission for a vehicle is provided with a selectable one-way braking clutch (SOWBC). The transmission has an input member connected for common rotation with one of the members of four planetary gear sets and an output member connected for common rotation with another of the members of the planetary gear sets. Four interconnecting members connect different members of the planetary gear sets for common rotation. A first brake is selectively engagable to ground the first member of the first planetary gear set to the stationary member. A first, a second, and a third rotating clutch are each selectively engagable to connect a different respective pair of the members of the planetary gear sets for common rotation. A selectable one-way braking clutch is configured to brake in one rotational direction and is selectively reversible to brake in an opposite rotational direction, and freewheels in some speed ratios.

    摘要: A method is provided for controlling engagement of a clutch which carries torque before, during and after a shifting event in a transmission which is connected to a throttle-controlled engine. The method includes providing a feed forward input command which increases as the engine torque increases and decreases as the engine torque decreases. A feed-back input command is provided as a function of the error between measured clutch slip and a reference slip profile. The feed-forward input command and feed-back input command are summed to provide a clutch control command for controlling engagement of the clutch before, during and after the shifting event to allow a desired amount of clutch slip to damp excitation of the transmission.
