GKN turns the CV joint inside-out

GKN Driveline is developing an innovative driveshaft concept that literally turns inside out the traditional configuration of the constant-velocity joint (CVJ), bringing potential benefits to both high-performance rear-wheel-drive vehicles-and future electric vehicles (EVs).

In a conventional design, CVJ housings face outward from the sideshaft, while the sealing systems on each end face inward; GKN has been testing a layout in which the CVJ reverses the positions of these components within a sideshaft system, integrating the CVJ housings within the sideshaft itself.
