An anti-lock braking and traction control system includes a sources of pressurized fluid (56,58,60), an actuator (54) adapted to selectively supply the pressurized fluid to wheel brakes (46,48,50,52) and a clutch (66,68,70). A controller (64) communicates ...

A transfer case includes a two-speed range unit (42), a friction clutch (46), an actuation mechanism (48), and a control system (50). The actuation mechanism (48) includes an electric motor (58), a geartrain (140) driven by the motor (58), a range actuator...

A torque transfer mechanism includes a multi-plate clutch assembly (90) that is operably disposed between a first rotary (94) and a second rotary member (100). A control system determines a desired quantity of torque to deliver to the second rotary member ...

A transfer case (22) having an input shaft driven by a powertrain, a first output shaft (32) adapted for connection to a first driveline (12), a second output shaft (42) adapted for connection to a second driveline (14), an interaxle differential operably ...

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 p...

A torque transfer mechanism is provided for controlling the magnitude of a clutch engagement force exerted on a multiple-plate clutch assembly (90) that is operably disposed between a first rotary and a second rotary member (32,42). The torque transfer mec...

A controllable, multi-mode, bi-directional overrunning clutch assembly (58) and a mode shift system (60) are adapted for use in a transfer case (16) for transferring drive torque from a primary output shaft (18) to a secondary output shaft (32) so as to es...
