Abstract
Disclosed is a differential transmission unit featuring active controlling of the moment distribution. Said differential transmission unit comprises a differential transmission () with two output shafts (), the cage () of said differential transmission () forming the input member, and one respective controlled frictional clutch () that is associated with an output shaft. The primary part () of the clutch is drivingly connected to the input member () while the secondary part () of the clutch is drivingly connected to the associated output shaft (), at least one of the driving connections being provided with an increased or reduced transmission ratio. In order to create a lightweight and small unit, the clutch () surrounds the associated output shaft (), the central axis () thereof is offset relative to the central axis () of the associated output shaft (), and the secondary part () of the clutch, which surrounds the associated output shaft (), is provided with an internally toothed gear rim () which meshes with an externally toothed wheel () on the associated output shaft.
