GKN Develops Electric-Drive Axles For Hybrid, EVs
GKN Driveline, a supplier of automotive driveline components and systems, has designed a new range of electric-drive axles ideal for use in both pure electric vehicles and for converting conventional vehicles into hybrids.
Most recently GKN Driveline has developed 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 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.
Rob Rickell, global engineering director of GKN Driveline, said: 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.
Furthermore our ability to partner with a wide variety of motor manufacturers allows us to provide the technology, the vehicle integration expertise and flexibility to meet any demand.
