Abstract
The present invention relates to a device for elastic linking between two parts (3, 5) in order to filter the vibratory excitations which are transmitted from one to the other, comprising: PA1 at least one linking element (7) between said parts (3, 5) comprising a transmission member (8) for the static force between said parts (3, 5), and an actuator (9) associated with said transmission member (8), PA1 at least one means of measurement (10) of a physical quantity which is representative of said vibratory excitations, and able to supply corresponding first signals, and PA1 electronic processing means (12) for said first signals in order to convert them into second control signals for said actuator (9). According to the invention, said measurement means (10) is mounted on said linking element (7).
