Abstract
An elastic bearing assembly for a driving assembly of a motor vehicle with at least engine and transmission side bearing arrangements, for holding the driving assembly with dampening of vibrations. In special arrangement, the motor or engine side bearings as well as the transmission side bearings exhibit different spring stiffness which are configured with respect to one another that the vertical vibration movements of the assembly are coupled with a rotational vibration movement about an assembly cross axis. Further the bearings are so arranged and configured that all other possible vibration or movement forms of vertical and rotational movement are substantially decoupled. During dampening of vibrations of the assembly caused by an external disturbance, respectfully all in and out spring movements of the harder bearings are hindered by an overlapping second higher frequency movement. A bearing arrangement of this type results in an advantageous quick dampening of vibrations.
