GKN Driveline has developed a family of lightweight constant velocity (CV)joint systems that enables rear-wheel drive platforms to save more than 4 kg. The VL3 CV joint increases torque capacity by up to 27% with noincrease in packaging size. Available in four sizes, the VL3-33ISM variant hasa torque capacity of 3300 N m in a package previously capable of deliveringonly 2600 N m. The system can also maintain performance while reducing packagesize by approximately 7%. With a plunging distance of 18 mm, the VL3 is thebest choice for a rear constant velocity sideshaft for medium working angleswith low axial forces and best in class minimum backlash. It uses a Monobloc tubularshaft and face spline connection to the wheel hub to achieve significantpackaging and weight advantages as well as noise, vibration, and harshness(NVH) behavior benefits. The VL3 Monobloc joint uses a track geometry with fourpairs of opposed ball tracks instead of three, which enables it to transmitmore torque to wheels within the same packaging space. The VL3 joint has been selected byBMW to launch on its 7 Series. For more information, visit www.gkndriveline.com.
