| 摘要 |
The present invention is a hydraulic vibration-proof support to be interposed between a vehicle body (11) and an engine (10), and which particularly comprises an armature (3) which can be joined with car body, a head (1) that can be joined with engine, a thick truncated cone-shaped wall (5) that joins to an armature circular length in head and which defines with armature a compensation chamber (B) which communicates with chamber (A) by a throttled passage (9). An active attenuation device is also foreseen, device comprising a piston (12) immersed in working chamber, an exciter (14) for this piston, and an electronic circuit (17) for this exciter actuation. Armature (3) forms on one hand a double container constituting bottoms (24, 25), arranged side by side, of two chambers (A and B), and on the other hand a box contained side by side of exciter and its actuating electronic circuit.
