| 20100198457 | SYSTEM AND METHOD FOR ADAPTIVE MOUNTING AN ASSEMBLY - A system for mounting an assembly, such as a motor vehicle engine, on a supporting structure such as a vehicle body. Disposed between the assembly and the supporting structure is a soft mount and/or a soft rubber spring featuring a damping and/or spring excursion along which the soft mount damps and/or adapts the load acting on the assembly. Also, disposed between the supporting structure and the assembly is an actuator which communicates an adaptive reaction force. A displacement of the assembly caused by the load along the damping or spring excursion of the soft mount or of the rubber spring can be cancelled out by a counter motion of the assembly prompted by the actuator. | 08-05-2010 |
