Device for the transmission of static forces and for the filtration of vibratory excitations between two components

A device for elastic connection between first and second components, for transmitting static forces from said first component to said second component along a vertical axis of the device and for filtering coaxial vibrations between said first and second components, said device comprising

• elastic return means (4) connected between said first and said second components,
• at least one swinging mass located at one end of a lever arm (6) said lever arm having another end pivotally connected to said first and second components,
• a first elongate element (2A) directly connected to said first component (2) and a second tubular elongate element (3A) directly connected to said second component (3),
• said first (2A) and second (3A) elongate elements being arranged coaxially and being capable of sliding longitudinally relative to each other,
• said lever arm (6) consisting of at least two portions (7,8) pivotally connected to one another, a first portion (7) of said lever arm (6) being pivotally connected to said first and second elongate elements (2A,3A), said second portion (8) of said lever arm (6) being pivotally connected to said first and second elongate elements (2A,3A), said second portion (8) being pivotally connected to said first portion (7) of said lever arm at one end and carrying said swinging mass (8) at an opposite end (8b).
