Abstract
Variatore continuo (1) di velocità provvisto di un albero di ingresso (3), di almeno un albero di uscita (4) e di un sistema (5) di accoppiamento dell'albero di ingresso (3) all'albero di uscita (4) atto a permettere una variazione continua del rapporto di trasmissione tra gli alberi (3) (4) stessi, il sistema è definito da un primo corpo rotante (6) troncoconico angolarmente solidale all'albero di uscita (4) e delimitato lateralmente da una superficie curva (7) convessa presentante un raggio di curvatura determinato, e da una pluralità di secondi corpi rotanti (8) troncoconici angolarmente solidali all'albero di ingresso (3) e disposti a corona del primo corpo rotante (6); ciascuno dei secondi corpi rotanti (8) è delimitato lateralmente da una relativa superficie curva (9) concava presentante un raggio di curvatura maggiore di quello della superficie curva (7) convessa relativa al primo corpo rotante (6) stesso, è premuto contro quest'ultimo da un dispositivo di forzamento (43) definito da una coppia di ruote dentate elicoidali (41) (42), ed è comandato da un dispositivo di comando (10) atto a generare un basculamento di ciascuno dei secondi, corpi rotanti (8) da e verso un asse (14) di rotazione del primo corpo rotante (6) per portare le superfici curve (7) (9) a cooperare fra loro in un unico punto (P) di tangenza.(Fig. 3)
