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.
Claims5
Differential gear having these features:
- An axially stationary planet carrier (1) drives two center gears (10, 11) over at least one planetary gear (8),
- each center gear (10, 11) drives an axially mobile output shaft (14, 15),
- at least one actuatable clutch (18 or 36) with an axially stationary and an axially mobile component (19, 20) connects the planet carrier (1) with an output shaft (15),
- the stationary clutch component (19) is corotatably connected with the output shaft (15),
- a gear housing (5) has an intermediate ring part (7) between a first and a second main component (4, 27);
- the planet carrier (1) is supported by a first bearing (3) in the first main component (4) and by a second bearing (6) in the intermediate ring part (7),
- the mobile clutch component (20) is corotatably connected with the planet carrier (1), characterized by these features:
- the stationary clutch component (19) is supported by two axial bearings (21, 22) axially fixed with respect to the second main component (27).
