  • Publication number: 20100198457
    Abstract: 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.

  • Patent number: 6631893
    Abstract: A pneumatically regulated classic bearing dampens hydraulically and decouples vibrations of a small amplitude using a freely displaceable element. The bearing can be engaged using a pneumatically activated control chamber, which has a miniature configuration and is located beneath the freely displaceable element, in such a way that the element forms a deformable or displaceable element for the control chamber. In place of a compensation regulation, in the control chamber, a shift to one of three possible, pneumatically determined control states preferably takes place. The states are VENTILATED, CLOSED and PRESSURIZED.

  • Patent number: 6123621
    Abstract: A joint for transmitting shifting forces from a gear-shifting system of a transmission to a transmission drive member includes a pair of joint parts (1, 2) frictionally locked to the transmission drive member and to the gear-shifting system, a coupling (3) mounted between the joint parts (1, 2) and an elastically deforming device. The elastic deforming device is a damper (4) substantially enclosing omnidirectionally the coupling (3) in such manner that when the joint is not transmitting shifting forces, the damper (4) keeps the coupling (3) spaced from the joint parts (1, 2).
