    摘要: The invention is directed to a four-wheel drive system for a vehicle having front and rear drive wheels driven by an engine and transmission assembly, and including a transfer case having a torque input shaft for receiving output torque from the vehicle engine and transmission assembly. A transfer gear assembly of the transfer case provides low and high speed power paths, and a shift mechanism is provided to shift between the low and high speed power paths. The system further includes an engine control module for controlling the engine fuel system and shifting of the transmission assembly between a plurality of vehicle gear ratios. A transfer case control module controls the shift mechanism for shifting between the low and high speed power paths. The transfer case control module is connected to the engine control module, and controls shifting between the low and high speed power paths by selectively controlling the engine fuel system to modify torque supplied to the transfer case, and/or shifting of the transmission assembly. The transfer case control module will thereafter shift the transfer case to a selected high or low speed power path when the output speed of the transmission assembly matches the output speed of the transfer case. The system allows the transfer case to be shifted from low range to high range or vice versa on-the-fly, while the vehicle is still moving and under power. The invention also provides a method of shifting a four-wheel drive system between low range and high range drive modes on-the-fly.

    摘要: A limited slip differential having a modified clutch pack mechanism located outside of the differential case. The mechanism include a planetary gear assembly disposed between a side gear and the clutch pack to facilitate the application of greater torque. A rotatable collar and cup-shape member together with a pair of planetary gear sets establish a driving connection through the differential case between the side gear and the clutch pack. Clutch plates are alternatively splined on the cup-shaped member and differential case to facilitate selectively coupling therebetween. The incorporation of the external clutch pack and planetary gear set facilitate the use of a greater diameter clutch plates resulting in greater torque capability.

    摘要: A vacuum operated speed range shifting mechanism for use in a drivetrain subassembly having input and output shafts, each being rotatably mounted within a support structure. The shifting mechanism comprises an annular shift sleeve surrounding and splined to the output shaft for rotation therewith, with the sleeve being axially moveable between first and second axial positions corresponding to low and high speed modes of operation of the drivetrain subassembly. The mechanism further includes a stationary annular housing disposed coaxially about the shift sleeve within the support structure. The housing is axially restrained by the support structure and defines an interior chamber. A flexible annular diaphragm is attached to the housing and disposed within the housing so as to divide the interior chamber into first and second annular cavities which are substantially hermetically sealed. A shift collar assembly is attached to the diaphragm and is disposed in surrounding relationship with the shift sleeve. In the preferred embodiment, evacuation of one of the first and second cavities and simultaneous venting of the other cavity to the atmosphere exerts a generally axial force on the shift collar assembly thereby forcing the shift sleeve to be disposed in one of the first and second axial positions to cause shifting to a desired drive mode.

The clutching assembly includes a locking collar and a clutch. The clutch may be engaged to transfer torque through the transfer sleeve to the output shaft through the flanged ring gear and the locking collar may be engaged to drivingly engage the transfer sleeve with the output shaft through the flanged ring gear.

    摘要: An active differential assembly provides speed control of an associated output shaft. A differential case is rotatably mounted within a housing to drive a pair of output shafts extending from the differential case in opposite directions for distributing driving force from the engine to wheels. A pair of planetary gear sets are one each disposed about a corresponding output shaft and includes a planetary ring gear, a sun gear fixed to the output shaft, and a planetary carrier rotatably supporting a plurality of planet gears operatively coupling the planetary ring gear with the sun gear. A brake mechanism is disposed between the planetary ring gear and the housing for selectively braking the planetary ring gear to thereby cause an associated increase in speed of the axle shaft.
