Intelligent power management company Eaton has been selected by a leading manufacturer of electrified vehicles to supply an 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 (ICE) 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 ICE to drive the front wheels.
According to Eaton, the ELocker is an electronic locking differential designed for drivers who want full control and traction on demand. It features net-forged gears to provide the strength and durability needed for off-road and recreational driving. Its electronic controls are designed to provide driver-selectable operation and added reliability over similar air-controlled solutions.
Activated by pressing a dash switch, the differential sends all available torque equally to the left and right wheels, providing maximum traction to overcome challenging terrain.
“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 of e-powertrain at Eaton’s Mobility Group.
“To meet this challenge, Eaton engineers made adjustments to traditional ELocker designs by utilizing premium designs, materials and coatings.”
