Method of damping vibration, active hydraulic anti-vibration mount and vehicle including such a mount

摘要

Active hydraulic anti-vibration mount comprising two support elements connected by an elastomer body partially delimiting a working chamber filled with liquid, this working chamber communicating by a throttled passage with a compensation chamber separated from said working chamber by a rigid partition. The rigid partition is penetrated by a first regulating nozzle closed by a movable exciting device, and a second regulating nozzle closed by a valve the movements of which are limited to correspond to an amplitude of variation in the volume of the working chamber which is less than 20% of the amplitude of the variations in volume generated by the exciting device.
