摘要： A drive axle assembly (34) for an all-wheel drive vehicle includes an adaptively controlled first hydraulic coupling (44) for providing front-to-rear torque transfer control to a first wheel and an adaptively controlled second hydraulic coupling (62) for providing front-to-rear torque control to a second wheel. The drive axle assembly is contained with a common housing (40) and communicates with a traction control system (68) to actively control actuation of the first and second hydraulic couplings based on the operating characteristics of the vehicle as detected by suitable sensors.

摘要： An improved geartrain includes a transmission unit (20) operatively attached to a longitudinally placed engine. The transmission unit incorporates a multi-speed transmission (42,44) and a lockable planetary differential (68) and further includes an input shaft (46), an output shaft (32,38), and connecting drive and driven gears. Two alternative torque paths are provided to a quill shaft (60) from the output shaft. One of these paths is a high-range path (64) and the other of these is a low-range path (66). The two torque paths are directed through a synchronizer clutch (62) between low-range and high-range. One end of the quill shaft (60) is connected to the low-high synchronizer clutch (62) and the other end is connected to the lockable differential (68,70). The differential end of the quill shaft is connected to the pinion carrier (280) of the differential. The torque delivered by the quill shaft is split by the differential when in its unlocked mode with a portion going to the rear wheels and a portion going to the front wheels. A front axle synchronizer clutch (72) assembly is provided to allow the front axle to be disengaged for two-wheel drive operation, in which case the differential is locked.
