A vibration isolation device is disclosed. More specifically the vibration isolation device of the present invention comprises means for decreasing the mount stiffness when loads above a threshold load value are applied to the device. The means for decreasing the mount stiffness comprises a shear pin (30) with shear locations that comprise annular grooves with semielliptical cross sections.
L'invention concerne un dispositif antivibration. Plus spécifiquement, le dispositif antivribration de la présente invention comprend des moyens destinés à diminuer la rigidité des points d'attache lorsque des charges dépassant une valeur de charge de seuil sont appliquées au dispositif. Le moyen destiné à diminuer la rigidité des points d'attache comprend une goupille de cisaillement présentant des emplacements de cisaillement comprenant des rainures annulaires à sections transversales semi-elliptiques.
