GKN develops electric drive axles for hybrid and electric vehicles
GKN Driveline has designed a new range of electric- drive axles for use in both pure electric vehicles and for converting conventional vehicles into hybrids.
Using products available within its extensive driveline portfolio, GKN has been able to design, validate and launch a variety of electric-drive axle products, which can incorporate passive and active limited-slip differentials, torque-vectoring technology and disconnect systems to maximise fuel economy and driving performance.
GKN Driveline has been a pioneer in electric drive axles, according to Ray Kuczera, engineering director – Americas for GKN Driveline. Since 2002, the company has produced more than 200,000 units for various vehicle manufacturers.
Most recently GKN Driveline announced the development of an electric-drive axle for use in the Peugeot 3008 HYbrid4. The axle allows the front-wheel-drive vehicles to have all-wheel-drive performance, supplemental traction and torque, hybrid fuel economy and the ability to operate in "all electric" drive mode with zero emissions.
Peugeot's electric drive axles incorporate GKN Driveline's proprietary disconnect clutch technology, which facilitates on-demand all-wheel-drive (AWD) and contributes to overall all-terrain functionality and fuel efficiency. The Peugeot HYbrid4 system has an electric motor with a maximum capacity of 27kW and a maximum torque of 200Nm. GKN Driveline's electric drive axle in the HYbrid4 is capable of delivering 1500Nm of torque to the vehicle's rear wheels. Other units currently being developed have ratings of up to 2500Nm, several of which will be ready for volume production by 2012.
"GKN's experience in volume production of electric-drive axles as well as our wide variety of limited slip differentials and torque vectoring products, allows us to offer a range of products from simple electric vehicles to vehicles designed for maximum performance and handling." said Rob Rickell, global engineering director of GKN Driveline. "Furthermore, our ability to partner with a wide variety of vehicle manufacturers allows us to provide the technology, the vehicle integration expertise and the flexibility to meet any demand."
