Abstract

Un palier de support pour une unité d'entraînement de disques durs ou similaire, ou pour d'autres appareils sensibles aux chocs ou générant des vibrations propres, comprend au moins trois, de préférence quatre éléments ou zones de support (12) qui relient de manière mobile limitée dans les sens axial et radial la plaque de base ou autre système de support (14) de l'unité d'entraînement de disques durs ou similaire (10) au boîtier ou à une structure portante (16) qui porte l'unité d'entraînement de disques durs ou similaire et qui peut être exposée à des vibrations ou qui est sensible à des vibrations. La plaque de base (14) ou le boîtier (16) sont pourvus chacun dans la zone de support (12) d'un passage de préférence circulaire. Au milieu ou à l'intérieur de ce passage est montée une membrane qui porte à son tour un disque relié à l'autre élément constitutif (boîtier ou plaque de base). Afin de pouvoir modifier les propriétés d'amortissement et de suspension entre le boîtier et la plaque de base, par exemple par modification de l'épaisseur et/ou du matériau de la membrane, les propriétés de suspension et d'amortissement de celle-ci sont variables.
