초록 ▼

Disclosed are embodiments of eccentric planetary traction drives for use in a driven turbocharger. The eccentric planetary provides torque-based loading of the traction interfaces in the traction drive. A loading planet has a larger outer diameter and has translative movement when torque is applied to the traction drive so that it is forced into a wedge gap between the turbo shaft and outer ring of the planetary drive. The torque capacity of the traction drive increases with an increase of torque demand.
