Eaton to supply ELocker differential system for new PHEV SUV | Autocar Professional

Intelligent power management company Eaton has announced that it has been selected by a leading manufacturer of electrified vehicles to supply its innovative ELocker differential system for use on a new plug-in electric hybrid (PHEV) SUV.

Unlike traditional PHEVs, which use an electric motor and internal combustion engine to power all the drive wheels, the new model leverages an electric motor to power the rear wheels and an electric motor or an optional internal combustion engine (ICE) driving the front wheels.

“The ELocker had to be designed to be compatible with fluid in an electric drive, which is lighter and has a lower viscosity than axle and transmission oils,” said Mark Kramer, business unit director, ePowertrain, Eaton’s Mobility Group. “To meet this challenge, Eaton engineers made adjustments to traditional ELocker designs by utilizing premium designs, materials, and coatings.”

The Eaton ELocker differential is an electronic locking differential designed for drivers who want full control and traction on demand. It features net-forged gears offering the strength and durability needed for off-road and recreational driving, while its electronic controls provide driver-selectable operation and added reliability over similar air-controlled products. By simply pressing a dash switch, the differential sends all available torque equally to the left and right wheels, providing maximum traction to overcome challenging terrain.
