PCT No. PCT/EP91/02297 Sec. 371 Date Jul. 30, 1993 Sec. 102(e) Date Jul. 30, 1993 PCT Filed Dec. 3, 1991 PCT Pub. No. WO92/13734 PCT Pub. Date Aug. 20, 1992.A drive assembly for a motor vehicle comprising a forward engine supported in two bearings on the vehicle body, a rearward drive unit supported by way of at least one elastic bearing, and a central support tube arranged in-between. This central support tube is connected on the forward end with the engine in a movable manner and on the rearward end with the drive unit in a rigid manner. A drive shaft or a central corrugated shaft which has a torque-transmitting joint in the area of the connection extends in the central support tube. The engine is connected with the drive unit by way of an uncoupling device which can be adapted as a function of main excitation directions of the engine and which comprises a connecting joint which holds the engine so that it can be angular moved in the main excitation directions. The connecting joint and/or a bearing device is used for the torque support. As a result, a drive assembly is provided which ensures a targeted uncoupling of vibrations of the engine caused by unbalanced forces of inertia and moments of inertia, with respect to the remaining drive assembly.
