EV Applications
The Posi differential is easily integrated into EV vehicles and eAxles, as it does not require electronics or software integration. The initial torque bias is tunable to the vehicle requirements and it offers reliable performance over the life of the vehicle, offering improved handling and control, especially in rear wheel drive vehicles.
The Eaton Posi limited slip differential (also know as Positraction) prevents wheel slip before it can get started. To do that, carbon disc clutch packs, preloaded by a central spring assembly, are located behind each differential side gear. When torque input increases the clamping load on the clutch packs increases. That causes the chatter-free clutch packs to grab and transfer power to the other wheel.
