Abstract
An anti-vibration device comprising first and second strength members interlinked by an elastomer body adapted to work in compression mode along a main vibration axis is disclosed. The first strength member is fitted in a slider of a support, in a direction of fitting perpendicular to the main vibration axis. The first strength member is blocked in the slider by snap-fitting.
Claims14
An anti-vibration device including:
- first and second strength members interconnected by an elastomer body adapted to be deformed at least relative to a main vibration axis, the first strength member being annular with its axis parallel to the main vibration axis;
- and
- a support provided with at least one slider formed by two facing parallel open grooves extending in a fitting direction substantially perpendicular to the main vibration axis, the first strength member including two exterior lateral ribs respectively fitting in the two grooves in the fitting direction, wherein the first strength member is made of plastic material and is blocked in the slider by a snap-fitting arrangement, and wherein the snap-fitting arrangement comprises a first shape formed in the first strength member and a counterpart shape formed in the support.
Vehicle having a body, an engine and an antivibratory device connecting the engine to the body, said antivibratory device comprising:
- first and second strength members interconnected by an elastomer body adapted to be deformed at least relative to a main vibration axis, the first strength member being annular with its axis parallel to the main vibration axis, the second strength member being fixed to the engine;
- and
- a support provided with at least one slider formed by two facing parallel open grooves extending in a fitting direction substantially perpendicular to the main vibration axis, the first strength member including two exterior lateral ribs respectively fitting in the two grooves in the fitting direction, the support being fixed to the vehicle body,
- wherein the first strength member is made of plastic material, and
- wherein the first strength member is blocked in the slider by a snap-fitting arrangement.
