Process for the manufacture of elastic elements with different stiffnesses along the three axes, which involves the press-fitting of cylindrical elements with rigid sleeves.

摘要

Process for the manufacture of elastic elements having rigidities differentiated in the three directions, of which the components formed from elastomeric rings (17, 20, 21) provided with cells (25) and adhesively bonded to concentric rigid reinforcements, such as (18), (19), (22), are prestressed and force-fitted, thus affording a ratio at least equal to 1.5 in the orthogonal radial rigidities. This is used for manufacturing anti-vibration insulating elements for suspensions of motor or rail vehicles. <IMAGE>
