    摘要： A hybrid transmission providing multiple modes of operation in a compact arrangement is provided and includes first and second planetary gear sets and first and second electric machines. An electric machine shaft directly couples the first planetary gear set to the second planetary gear set and the second electric machine to the second planetary gear set. The second electric machine is selectively directly coupled to an output shaft via a first clutch mechanism, and indirectly coupled to the output shaft via the second planetary gear set and a drive shaft, which extends parallel to the electric machine shaft and external to the second electric machine. A second clutch mechanism selectively couples the first electric machine to a carrier of the second planetary gear set and a third clutch mechanism selectively couples a ring gear of the second planetary gear set to a hybrid drive unit housing.

    摘要： A multi-speed transmission includes a first power transmission module driven by an input shaft. A second power transmission module is driven by the first power transmission module. A third power transmission module is driven by the second power transmission module and drives an output shaft. Each power transmission module includes an actuation mechanism and a planetary gearset. Each actuation mechanism controls the output of its respective planetary gearset to one of a first gear ratio and a second gear ratio. One of the actuation mechanisms includes a clutch and a spring biasing a member to rotate and cause a corresponding actuation of the clutch. The clutch causes two members of the respective planetary gearset to rotate at substantially the same speed and provide the first gear ratio. The actuation mechanism selectively restricts the member from rotating and prevent actuation of the clutch to provide the second gear ratio.

    摘要： A torque transfer mechanism having a multi-plate friction clutch connecting a pair of rotary members and an electrohydraulic clutch system for controlling engagement of the friction clutch. The electrohydraulic clutch system can include an actuator with first and second components with a plurality of actuation chambers that are employed to control the position of the second component relative to the first component. Relatively high pressure fluid may be directed through or around one or more bypassed portions of the actuation chambers when relatively low compressive clutch engagement forces are to be exerted on the friction clutch. The bypassed portions of the actuation chambers may be sequentially or progressively operated based on a position of the second component relative to the first component to increase an amount of force that is applied by actuator.

    摘要： A clutch actuator for controlling engagement of a friction clutch and having a first actuator plate rotatable about an axis, a second actuator plate adjacent to the first actuator plate, and a ballramp unit disposed between the first and second actuator plates. A piston assembly acts to induce rotation of the first actuator plate relative to the second actuator plate. Relative rotation between the first actuator plate and the second actuator plate induces linear movement of one of the first and second actuator plates along the axis to regulate engagement of the friction clutch.

    摘要： A drive axle assembly includes a pair of axleshafts connected to a pair of wheels and a drive mechanism for selectively coupling a driven input shaft to one or both of the axleshafts. The drive mechanism includes first and second drive units that can be selectively engaged to control the magnitude of the drive torque transferred and the relative rotary speed between the input shaft and the axleshafts. Each drive unit includes a planetary gearset disposed between the input shaft and its corresponding axleshaft, a bi-directional overrunning clutch and a mode clutch that may be activated to cause the planetary gearset to establish different speed ratio drive connections between the input shaft and the axleshaft. A control system including an electronic control unit (ECU) and sensors are provided to control actuation of the mode clutches so as to control the side-to-side traction characteristics of the drive axle assembly.
