FORDONSTRANSMISSION MED PLANETVEXEL

摘要

A planetary gearing arrangement having a plurality of interconnected planetary gear sets controlled by friction drive establishing devices such as clutches and brakes for selectively establishing a plurality of forward drive ratios and a reverse drive ratio. The number of forward drive ratios available is one greater than the number of friction drive establishing devices. Each ratio change between the forward drives is accomplished by a single transition interchange of the friction drive establishing devices.
