The present invention relates to a suspension for an assembly generating, absorbing, and/or transmitting torque in the drive train of a motor vehicle. In particular, the invention relates to a suspension of an electric motor between the engine block of a combustion engine and the transmission housing of a downstream manual or automatic transmission. The electric motor then optionally serves as a starter of the combustion engine, as a charging generator for the automobile battery, as a torsional-vibration absorber of the combustion engine, or, with the combustion engine shut down, as an electric drive. This concept has been explained under differently weighting the individual aspects in a number of patent applications (e.g. DE 33 06 481, DE 44 06 482, DE 44 47 537, DE 44 47 574, DE 195 32 135, DE 195 32 128, DE 195 32 136, DE 195 32 163, DE 195 49 259, DE 195 32 164, DE 32 129 filed by Clouth Gummiwerke AG, Cologne, Germany). A suspension for an assembly generating, absorbing, and/or transmitting torque in the drive train of a motor vehicle with a combustion engine, with the assembly including materials with a thermal expansion coefficient different from the material of the engine block of the combustion engine , and a first non-rotating part of the assembly being connected with the engine block, and a second rotating part of the assembly being connected with an output shaft protruding from the engine block, and with the first and the second part being designed so as to encompass the output shaft at least partially, and with the first non-rotating part of the assembly being connected with the engine block of the combustion engine via a coupling element in a manner so as to be essentially secured against rotation and resilient in the radial direction.
