Abstract
Variatore continuo (1) di velocità, in cui un gruppo (15) di collegamento atto a variare in maniera continua un rapporto di trasmissione tra due alberi (6) (7) è provvisto di una campana (37) presentante un proprio asse (8), di una corona di rulli (16) conici alloggiati all'interno della campana (37) stessa e delimitati, ciascuno, da una relativa superficie laterale (18) esterna cooperante con una superficie (38) interna della campana (37) stessa in un unico punto (P) di tangenza, e di un organo (44) di comando alloggiato all'interno della corona di rulli (16) e mobile nei due sensi lungo l'asse (8) della campana (37) per determinare un basculamento dei rulli (16) stessi rispetto alla campana (37), ed uno spostamento dei punti (P) di tangenza lungo le generatrici dei relativi rulli (16).[Fig.1].
