Abstract

Patente de Invenção:<B>"'AMORTECEDOR DE VIBRAçãO SINTONIZADO MULTIDIRECIONAL".<D>Um Amortecedor de Vibração Sintonizada Multidirecional (MDTVA) (23) que inclui uma primeira massa de sintonia (32) que vibra a uma primeira freq³ência ressonante fn1 ao longo de um primeiro eixo geométrico , uma segunda massa de sintonia (34) que vibra à primeira freq³ência ressonante ao longo do dito primeiro eixo geométrico e também a uma segunda freq³ência ressonante fn2 ao longo de um segundo eixo geométrico, um elemento de base (21), uma primeira mola (35) interconectada de modo flexível entre o elemento de base (21) e a primeira massa de sintonia (32), sendo que a primeira mola (35) substancialmente restringe o movimento da primeira massa de sintonia (32) para movimento ao longo de um primeiro eixo geométrico apenas, e uma segunda mola (36) interconectada de modo flexível entre a primeira massa de sintonia (32) e a segunda massa de sintonia (34), de modo que o movimento relativo da dita segunda massa de sintonia (34) na dita segunda freq³ência fn2 esteja ao longo do segundo eixo geométrico substancialmente perpendicular ao primeiro eixo geométrico. Em outro aspecto, as primeira e segunda freq³ências ressonantes fn1 e fn2 podem ser sintonizadas independentemente por adição de massas com aparência de arruela e/ou ajuste da posição da segunda massa de sintonia (34) e o MDTVA (23) pode ser usado no sistema de isolamento de um veículo.
