Abstract
A drive axle for an all-wheel drive vehicle includes an adaptively controlled first hydraulic coupling for providing front-to-rear torque transfer control and a passively controlled second hydraulic coupling for providing side-to-side limited slip and torque biasing control. The drive axle is contained with a common housing and communicates with a tractor control system to actively control actuation of the first hydraulic coupling based on the operating characteristics of the vehicle as detected by suitable sensors.
