ZF-ADM

The ZF-ADM – Automatic Drive-Train Management - is an electronic system which automatically controls all axle and transfer case differential lock shifting functions and excludes incorrect handling.

• Central components include dog clutches assembled in axles and the transfer case
• Actuated by the ADM electronic control unit, the specific dog clutches in the differentials allows shifting on the fly
• Speeds of all wheels are measured and compared with each other by using the signals of the installed speed sensors
• When slip is detected on one of the wheels, the control unit automatically activates the differential locks within a millisecond
• Locks remain active only as long as there is missing traction on one or more wheels
• Differential locks open automatically by spring force when not needed anymore 
• Helps prevent mechanical damage to the driveline and incorrect operation by inexperienced drivers
• Eliminates need for driver to pay permanent attention to ground conditions or stop in order to manually engage differential locks
• Plastic housing reduces weight and space concerns
