Abstract

The invention concerns a motor-vehicle drive train (1) with a drive motor (2), a transmission (3) and an axle (6). An output shaft (7) of the transmission (3) is attached to a joint shaft (9) by a joint (8). Another joint (10) transmits the drive from the joint shaft (9) to an input shaft (11) of a differential transmission (4). In order to allow the joint shaft (9) to have a W-configuration, the drive motor (2) and the transmission (3) are mounted so that they can pivot about the axle (6). All divergences existing in a longitudinal direction of the drive train (1) immediately produce large angles of inflection in the joints. Irregularities in the drive train are hereby avoided. In addition to reducing the load on the joints, the generation of disagreeable noises is avoided. The invention is particularly used in utility vehicles such as employed in the construction industry and in agriculture.
