Title:
DIFFERENTIAL
Document Type and Number:
WIPO Patent Application WO/2014/121776
Kind Code:
A3
Abstract:
The invention relates to a differential, comprising a planet carrier, a planet carrier bearing unit for bearing the planet carrier so that it can rotate about an axis of rotation, a first output sun gear which is arranged coaxial with the axis of rotation and forms a first output gear toothing, a second output sun gear which is likewise arranged coaxial with the axis of rotation and forms a second output gear toothing, and a revolving planet arrangement which couples the first and second output sun gears in terms of their gearing so as to be rotatable in opposite directions. According to the invention, an annular plate element is connected to at least one of the output sun gears and forms a guide structure via which the corresponding output sun gear is supported such as to be radially rotatable in the planet carrier. The invention advantageously allows the creation of a differential in which the output sun gears are rotatably guided in the planet carrier with ease and are accurately centered.
