摘要： The present invention is a transfer case incorporating the use of a single actuator having an input member selectively engagable to a primary output member, an actuator operatively associated with a clutch assembly and a range selector, a first one-way clutch operably associated with the actuator, and a second one-way clutch operably associated with the actuator. When the actuator is actuated in a first direction, the first one-way clutch will activate the range selector to couple the input member and the primary output member to have either of a direct drive ratio, or a reduced gear ratio. When the actuator is actuated in a second direction, the actuator will actuate the second one-way clutch to engage the clutch assembly, transferring rotational force from the primary output member to a secondary output member.

摘要： An electromagnetic clutch assembly having a solenoid activated ball ramp operator provides reduced power consumption and improved control. The electromagnetic clutch assembly includes a primary or pilot friction clutch pack and a secondary or main friction clutch pack. An annular solenoid coil cooperates with an annular operator or plunger. When the coil is energized, the annular plunger translates and compresses the primary or pilot friction clutch pack. Activation of the pilot clutch pack retards motion of one of the members of the ball ramp operator which, in turn, compresses a secondary or main friction clutch pack disposed across the input and output members.

摘要： The transmission of the present invention includes a multi-speed geartrain comprised of an input shaft, a mainshaft, and a plurality of constant-mesh gearsets arranged for selectively coupling the mainshaft to the input shaft for driven rotation at various speed ratios. The mainshaft can be selectively coupled to the power transfer arrangement for establishing two alternative power transmission routes. In particular, the range shift mechanism is provided for establishing a high-range power transmission route and a low-range power transmission route from the mainshaft to a quill shaft which, in turn, drives the interaxle differential. The torque delivered by the quill shaft is split by the interaxle differential between the front and rear drivelines to establish the full-time four-wheel high-range and low-range drive modes. Optionally, the torque transfer apparatus can be provided for controlling speed differentiation across the interaxle differential or in place of the interaxle differential for on-demand four-wheel drive operation. The torque transfer apparatus can be a speed-sensitive device or an electronically-controlled transfer clutch.

摘要： A controlled differential actuator particularly adapted for differential applications for motor vehicle powertrains. The differential operator incorporates an electromagnetically applied first or primary clutch coupled to a second multi-disc clutch pack through a ball ramp operator. Energization of the solenoid coil selectively applies the main clutch pack which is coupled to a differential carrier and one of the axle half shafts connected with the differential assembly. Modulation of current applied to the solenoid coil allows a selective frictional coupling between the differential axle half shafts which provides desirable traction features for the associated motor vehicle.
