Mechanical Locking Differential (M-Locker)

Eaton's MLocker® mechanical locking differential provides drivers best-in-class traction without the need for push-buttons, shift knobs or other intervention. Utilizing a flyweight mechanism and self-energizing clutch, Eaton MLocker engages in low traction situations when a wheel speed difference of 100 RPM or greater is detected. Automatic locking takes place within a fraction of a second, providing the driver with increased safety and confidence when traveling on wet or icy roads, gravel, mud and dirt. The mechanical locker is also compatible with existing anti-lock brake and vehicle stability systems, which simplifies platform integration for global OEMs.

MLocker® Operation

During normal driving conditions, the MLocker functions as a light-bias limited slip differential. When a low-traction situation occurs that causes a wheel speed difference greater than 100 RPM, a flyweight mechanism opens to engage a latching bracket. The stopped flyweight triggers a self-energizing clutch system, forcing a cam plate to ramp upon a side gear. This continues until both axles turn at the same speed (full lock), which prevents further wheel slip. When the need for improved traction is no more - unlocking occurs automatically and the differential resumes normal operation.
