Abstract

A planetary transfer transmission for the drive of two vehicle axles of a motor vehicle, whereby a central input shaft, a coaxial central output shaft, and a concentric output shaft, in a torsionally fixed way, are respectively connected with one gear element of a planetary wheel gear that can be locked by a locking multi-disk clutch. An input wheel of an axle offset gear, that can be driven by the concentric output shaft, the planetary wheel transmission, and the locking multi-disk clutch are arranged in line to one another. The input wheel is disposed on the side of the locking multi-disk clutch that is opposed to the planetary wheel gear and, in a torsionally fixed way, is held on an outer hollow shaft that is rotatably disposed on the concentric output shaft and can be brought into driving connection with the concentric output shaft by an axle-connecting multi-disk clutch that is arranged on the side of the input wheel that is opposed to the locking multi-disk clutch. In this way, the axle offset gear is in a favorable position with respect to the driving engine and the whole drive train to the disconnected driving axle, in the case of a single-axle drive, is separated from the…
