GKN Driveline has revealed details of its new family of lightweight constant velocity joint systems that help rear-wheel drive platforms to save more than 4kg.
The supplier says that the higher performing drivelines with less rotating mass will help OEMs to meet strict CO₂ reduction strategies.
Karl Berger, GKN Driveline’s senior director of constant velocity joints, said, “GKN innovations make vehicles better to drive and more efficient. For premium rear-wheel drive programmes seeking CO₂ emissions reductions, this system represents a step forward in weight, efficiency, performance and refinement.”
The new 7% smaller VL3 CV joint increases torque capacity by up to 27% with no increase in packaging size, says GKN. It also says that its VL3-33ISM variant, available in four sizes, now has a torque capacity of 3,300Nm in a package previously capable of delivering only 2,600Nm.
The VL3 uses a monobloc tubular shaft and face spline connection to the wheel hub to achieve significant packaging and weight advantages as well as NVH behavior benefits. The result, claims GKN, is a more refined driving experience.
