Auto diff lock gives Isuzu SUVs keys to the desert

ISUZU MAKES NEW TRACKS:  The (strangely named) Isuzu mu-X SUV now offers an option of a superior differential lock for when the going gets, well, like that above.   Image: Supplied

PORT ELIZABETH, South Africa – Isuzu’s seven-seat mu-X  SUV now offers a mechanical diff-lock for 4×4 and 4×2 models.

The Eaton MLocker is said to be a mechanical locking differential which provides automatic additional. Technically, the MLocker works as a light-bias limited-slip differential during normal driving or as a locked diff when conditions demand.

The MLocker locks, The Corner was told, automatically in a fraction of a second to maintain traction over or through wet roads, icy conditions, gravel, mud, dirt and sand.

AUTOMATIC CLUTCH

The MLocker engages when a low-traction situation causes a wheel rotation difference of 100rpm. A flyweight mechanism opens to engage a latching bracket and the stopped flyweight triggers a self-energising clutch system, forcing a cam plate to ramp up on a side gear.

This continues until each axle rotates at the same speed (full axle lock), which prevents further wheel slip. Unlocking occurs automatically allowing the differential to resume normal operation.

The MLocker does not interfere with vehicle safety systems as it is automatically disengages from 30km/h.

The Eaton MLocker is available as a R11 500 (incl VAT) option on all mu-X models.
