An auxiliary damper (12) is provided for a passenger cab (13) on heavy equipment or the like, the damper (12) being contained within the confines of the primary suspension system (11) and being secured to a first one of a supported element and a support to provide surface effect damping as needed to damp high-amplitude, low-frequency vibration in the region of the resonant frequency of the primary suspension (11). An elastomeric sleeve (16) is bonded to a rigid sleeve member (14) which surrounds the securement bolt (17) for the primary mount. A spool member (18) with internal protrusions (26) engagingly surrounds the elastomeric sleeve (16). The spool (18) has upper and lower flanges (22, 24) which overlie and underlie, respectively, in non-engaged relationship, the second of a supported element and a support. When there is low-amplitude, high frequency motion of the support, this non-engaged relationship allows the supported element to be isolated from such motion. When the amplitude of the vibration becomes large enough as, for example, near resonance, the spool (18) of the auxiliary damper (12) engages its supported element or support and dissipates the vibrational energy as heat to effectively damp the large amplitude motion and maintain a comfortable ride.

La présente invention concerne un amortisseur auxiliaire (12) destiné à une cabine pour passagers (13), sur une machine lourde ou autre, et contenu à l'intérieur des limites du système de suspension primaire (11). Cet amortisseur (12) est fixé à un premier de deux organes qui sont un élément supporté et un support, afin de donner un amortissement à effet de surface en fonction des besoins, pour amortir les vibrations basse fréquence de forte amplitude, dans la zone de la fréquence de résonance de la suspension primaire (11). Un manchon élastomère (16) est relié à un manchon rigide (14) qui entoure le boulon de fixation (17) du montage primaire. Une bobine (18) présentant des saillies intérieures (26) entoure le manchon élastomère (16), avec lequel il est en contact. La bobine (18) a des brides supérieure et inférieure (22, 24) qui se trouvent respectivement au-dessus et au-dessous, sans contact, du deuxième des deux organes qui sont un élément supporté et un support. Quand le support effectue des mouvements à haute fréquence et de faible amplitude, cette relation sans contact permet à l'élément supporté d'être isolé de tels mouvements. Quand l'amplitude des vibrations augmente de façon à se rapprocher, par exemple, de la résonance, la bobine (18) de l'amortisseur auxiliaire (12) vient en contact avec son élément supporté ou son support et dissipe l'énergie de vibration sous forme de chaleur, ce qui amortit de manière efficace les mouvements de forte amplitude et maintient le confort du trajet dans le véhicule.
