Eaton, a power management company headquartered in Galesburg, east of Kalamazoo, has launched an extensive lineup of specialized differentials for electrified vehicles with comparable performance to traditional internal combustion engine vehicles.

The traction control family of differentials can provide improved in adverse conditions, such as snow and mud, and improved stability while trailering. Eaton has been supplying differentials to the EV market since 2015 and expanded its offerings to keep up with the passenger vehicle market that is becoming increasingly electrified.

“Eaton conducts a total system analysis, using state-of-the-art tools and in-house know-how, to design a differential for electrified vehicles optimized for efficiency, reliability and manufacturing,” says Brent Pawlak, director of Eaton’s vehicle group.

“We also can partner with an OEM to design and develop a differential to specifications and requirements, including torque levels, duty cycles, fatigue and size requirements, as EVs often require compact components and unique torque requirements that can be integrated into electrified drivetrains.”

Among the full range lineup are the automatic limited-slip, automatic locking, and electronic selectable locking differentials. Each differential is engineered, tested, and validated for a variety of traction control applications. Performance is verified at Eaton’s Proving Ground testing complex in Marshall, east of Battle Creek.

The Truetrac is a helical-gear limited-slip differential that maximizes wheel traction and enhances driving and handling characteristics. It is easily integrated into compact packaging spaces and has high power density capacity.

The ELocker allows for maximum driveline flexibility, allowing users to switch from a fully open to a fully locked axle at the touch of a button. It can also be integrated in the vehicle for auto-locking. This differential features high torque capacity and range.

IntelliTrac is a smart, electronically controlled limited-slip differential that is fully integrates into the vehicle to provide instant response and optimized vehicle performance at any speed or traction condition.

The MLocker is an automatic locking differential which strong traction without the need for buttons, shift knobs, or other features that require driver intervention. It has a low integration cost and improves towing and off-road performance.

Posi is a limited slip differential which automatically prevents wheel slip before it starts. It can be easily integrated into most axle designs and tuned for application requirements. The final product, Open, is a compact open differential which allows a cost-effective solution for managing torque between left and right wheels.

Eaton provides sustainable solutions that help its customers effectively manage electrical, hydraulic, and mechanical power more safely, efficiently, and reliably. It sells products in 175 countries and has approximately 85,000 employees.
