Lepelletier Actuation (6-Speed)
Clutch Arrangement for a 6-Speed Lepelletier Gearbox
The Lepelletier 6-Speed Actuation component is intended for use with a Ravigneaux Gear and a Planetary Gear (see Ravigneaux Gear and Planetary Gear). The internal structure of this component is shown below. The combination of the clutches and the activation table, enables the user to easily create a 6-Speed Lepelletier Gearbox.
