Abstract

In a differential, a clutch links an axially stationary planet carrier with an axially mobile output shaft so that they rotate together. Engaging gears with engaging surfaces parallel to the main axis link an axially stationary clutch part with the output shaft so that they rotate together. Engaging gears with engaging surfaces parallel to the main axis link an axially mobile clutch part with the planet carrier so that they rotate together.
