Eaton E Locker Locking Differential
Lockers, Limited Slips, Differentials and the sport of Offroading.
The ELocker is built with precision-forged gears that are designed to mesh perfectly, providing improved strength and durability over a standard cut gear. Its ease of installation, reliability and push-button activation make ELocker an absolute must for all traction and off-road performance applications.
The key to getting in - and out - of tough country is traction. It's getting power to the wheels that need it. The ones that can push - or pull - to get you over, under around and through the tough stuff. That means you need the control. You need to be able to lock the rear or front differential, at will, so power is sent equally to both wheels. And in real extremes? Well, you may just need to lock both... How are you going to do that? With the Electronic Locker from Eaton. The ELocker™ Differential. Expressly designed for 4-wheel drive systems, this thing is something else. It gives you the ability to lock the differentials when YOU decide it's necessary. And when you do, you have power at both ends of the axle. Lock both differentials? Drive power at all four wheels. Equal power. And the power is there until you disengage it. The power is at both wheels as long as the differential is locked. Imagine that. Putting the driver in control of traction. A Quick Look At How it Works Basically, when the system is engaged, friction between an armature and an electromagnet apply force to a "ball ramp" mechanism. This forces the ball ramp's bearings out of their pockets
and up the ramp. That action, in turn, pushes the system's locking pins into matching holes located on the back of the side gear. That locks the axle, and drives torque to both wheels. Eaton's ELocker™ Differential brings you the ultimate in control, power and traction. And it does it all with the touch of a button.
The Eaton E-Locker is an electric-locking selectable differential. It instantaneously goes from a fully open mode to a full-spool mode with the push of a dash-mounted engagement button. The E-Locker features a rebuildable design, though with precision forged gears and a lack of any external module, air compressor, or air lines, the reliability is almost unquestionable.
When activated, an electromagnet engages a ball ramp, forcing three ball bearings out of a pocket, which in turn pushes six locking pins into corresponding slots. This causes the side gears to lock to the case and prevents the spider and side gears from turning. Consequently, this locks the axleshafts to the carrier, turning a fully open differential into a full spool.
