Abstract
Un complesso di cuscinetto centrale comprende un cuscinetto a rullo atto a ricevere ed a supportare in modo girevole un albero di accoppiamento ed una staffa atto ad essere fissata al telaio di un veicolo. E' previsto un organo di supporto il quale sostiene il cuscinetto a rullo nella staffa. L'organo di supporto comprende un bulbo formato in materiale elastomero. Il bulbo contiene un fluido reologico che presenta una significativa variazione della sua capacità di scorrere o di tagliare a seguito di applicazione di un appropriato campo di energia. Preferibilmente il bulbo contiene un fluido magnetico magnetoreologico. Variando la potenza applicata ad un elettromagnete collocato in adiacenza al bulbo, le caratteristiche di smorzamento delle vibrazioni dell'organo di supporto possono essere fatte variare in dipendenza dalle condizioni di funzionamento del veicolo.
