Antivibration device, antivibration system comprising such a device and manufacturing process

摘要

The device (1) has a hydraulic antivibration support (S) including rigid armatures (2, 3) connected together by a bell shaped elastomer body (4), where the armature (3) is cylindrical and is made of plastic material. An inverse U-shaped limiting bonnet (L) is fixed on a receiving unit (31) e.g. longitudinal sill, by locking the armature (3) against the receiving unit. The bonnet limits displacement of the armature (2) along a vertical direction (Z) and a direction (Y) that is perpendicular to the direction (Z). The armature (3) is clipped with the bonnet by interlocking, in the direction (Z). An independent claim is also included for a method for fabricating an antivibration system.
