GKN is first Tier One supplier to develop complete all-wheel drive system

GKN Driveline has designed, developed and now manufactures intelligent all-wheel drive (AWD) systems for a new AWD global platform launched by FCA US LLC (FCA).

The FCA platform sources the complete driveline, from transmission to wheel, from GKN, including AWD, AWD Disconnect and front-wheel drive variants. Every part of the system, from the propshafts to the rear differential module to the sideshafts, is designed by GKN and manufactured by the company’s global production facilities.

To meet the tight packaging targets of a compact SUV and small city car, GKN integrated a number of key features of the driveline system, saving space and optimising cost and efficiency. Instead of a standard power transfer unit, GKN developed a monobloc housing that fully integrates the propshaft's constant velocity joint.

"This is a new technical solution and a remarkable piece of engineering, which involved close inter-functional development," said Global Programme Director, GKN Driveline, Hannes Prenn. He addded, "The result is a high-performance system that offers optimum efficiency, weight and packaging. The arrangement also yields superior noise, vibration and harshness characteristics, helping to create a more refined driving experience."

The same hardware is able to fulfill requirements for different brands and classes of vehicle, from city cars to off-roaders. GKN's software tuning experts ensure the system is able to meet different brands' specific requirements. A city car version may require low drag torques and torque biasing, while a model intended for off-road use requires high traction and torque.
