Axle Traction Control Options
Driver Controlled Differential Lock (DCDL)
OVERVIEW Axles equipped with DCDL have a shiftable collar with internal splines or clutch teeth that mate with external splines or clutch teeth on the differential case. The collar can be engaged or dis-engaged from the differential case with a cab mounted switch controlled by the driver. When road conditions are good the dis-engaged position is selected operating as a standard wheel differential. When road surfaces deteriorate the driver ‘flips the switch’ to activate the DCDL moving the collar into engagement with the differential case spline or teeth and mechanically locking out differential action. This allows torque to be delivered to any wheel up to the point of slip. If one wheel is on ice and the other on a good surface additional torque is delivered to the side with the better traction. When road conditions improve the driver de-selects the feature moving the clutch collar into the dis-engaged position. The DCDL can be shifted while the vehicle is stationary or moving as long as both wheels are turning at same speed. When engaged both wheels are forced to turn at the same speed. The driver may feel a tendency for the vehicle to move straight ahead when turning and may hear tires ‘scrubbing’. This is normal and results from the differential being locked to maximize traction. It is important for the driver to dis-engage the DCDL feature when road conditions improve to prevent tire wear and maximize vehicle control.

FEATURES & BENEFITS FEATURES
BENEFITS
Driver Selected Engage / Dis-engage
Operator can control usage by engaging only when required and dis-engaging when on good road surfaces for optimal performance.
When engaged maximum torque can be delivered to each wheel up to slip point.
Maximizes mobility
''Shift on fly' capability - can be engaged and dis-engaged when vehicle moving as long as wheels turning at same speed.
Engaging while moving ensures vehicle maintains momentum
Fewer parts compared to some other traction control devices
No special lubricants required as in some 'clutch plate' type traction differentials
