The new module integrates a water-cooled electric motor and inverter with a single speed eAxle reduction gearbox, generating 65kW of power and up to 2,000Nm of torque to the rear wheels.
GKN Driveline chief executive Phil Swash says tighter integration of electric drivelines improves system efficiency and gives automakers better packaging and assembly options.
“A new generation of vehicles is making hybridisation integral to platform strategies,” comments Swash.
“These drivelines require the higher levels of system integration that GKN eAxle electric drive modules deliver. By pioneering development, GKN is positioned to help automakers turn electric propulsion into exciting new hybrid all-wheel drives.”
“This is the first all-in-one eDrive system to replace external wiring with a bus bar and to eliminate unnecessary mechanical interfaces,” aadds Peter Moelgg, chief executive of GKN Driveline’s eDrive and AWD business.
“The result is an eDrive system with higher power density that is simpler to install.”
GKN Driveline’s eDrive module measures just 300mm by 325mm and weighs 54kg, making it around 20mm narrower and 2.5kg lighter than comparable systems.
GKN launched the world’s first two-speed eAxle in the plug-in hybrid BMW i8 and also supplies the eAxle on the Volvo XC90 T8 Twin Engine PHEV programme.
