A gear support comprises an elongate carrier portion which is oriented along a longitudinal axis, and a flange portion at one end of the carrier portion. The flange portion serves for fastening the gear support to a case of the gear, and a bearing portion in the region of an opposite end of the carrier portion serves for mounting the gear support on the motor vehicle. The carrier portion has two mutually opposite longitudinal spars, between which ribs extend, the longitudinal spars and the ribs being produced in one piece with one another.

A drive assembly for motor vehicles comprises a front power unit which is elastically supported at the vehicle body and which is rigidly connected with a rear drive unit by means of a center tube through which a drive shaft extends. The front area of the center tube has a low bending stress and is connected to the power unit. This front area of the center tube has at least one longitudinal slot which is axially limited in its length and which is arranged in a vertical longitudinal center plane of the center tube. The slot causes a reduction of the torsional rigidity while, at the same time, the bending rigidity of the center tube is maintained. As a result, the torsional natural frequency of the assembly is reduced so that torsional resonance and vibrations at the transmission line are avoided during the driving operation.
