A hydraulic vibration-damping support comprising two strength members interconnected by an elastomer body which defines a working chamber communicating with a compensation chamber via a constricted passage. The two hydraulic chambers are separated from each other by a rigid partition formed by two gratings disposed one on the other, and a decoupling flap is mounted with a small amount of clearance between the gratings. The decoupling flap is provided with two catches that are clipped onto one of the gratings.

A suspension fitting for a motor vehicle exhaust system, the fitting comprising a top and bottom strength members interconnected by a resilient system comprising firstly a single central support arm and secondly a flexible limiting ring surrounding the support arm to limit relative travel between the strength members in a direction corresponding to the support arm lengthening. The top and bottom strength members have respective downwardly and upwardly extending rigid limbs which are placed facing each other on a horizontal axis perpendicular to the general direction of the exhaust system so as to come into abutment against each other and limit relative travel between the strength members along the axis.

A suspension for a motor vehicle exhaust pipe, the suspension comprising an upper strength member 3 suitable for securing to the body 5 of the vehicle, and a lower strength member 4 suitable for securing to an exhaust pipe 6, the two strength members being interconnected by a resilient system. Such a suspension is characterized in that said resilient system comprises two crossed resilient loops 1, 2 each incorporating a ring B of material having a high modulus of elasticity that is coated in rubber C, the loops 1, 2 being fixed to each of the strength members 3, 4 at two diametrically-opposite locations of their respective circumferences. The invention also relates to an assembly of such a suspension, the vehicle body, and the exhaust pipe.

A hydraulic antivibration support comprises a strength member connected to a plate by an elastomer body whose base is pressed against the plate to define two hydraulic chambers and a narrow channel all filled with liquid. A perforated sheet metal insert embedded in the base of the elastomer body is crimped to the plate via two fixing edges that are interconnected by two free edges of the base. The perforated insert has a stamped corrugation which defines the narrow channel and whose outer side wall extends around the entire periphery of the plate.
