Abstract

Trasmissione meccanica riduttrice da interporre fra motore e mozzo della ruota motrice di biciclette a motore ausiliario comportante una sola interruzione della catena cinematica in corrispondenza della riduzione finale. Detta interruzione è realizzata attraverso un innesto a frizione attivato automaticamente dalla coppia di reazione del motore ausiliario della bicicletta preferibilmente tramite mezzi a piano inclinato.Fig. 2.Mechanical reduction gearbox to be interposed between the motor and the hub of the driving wheel of bicycles with an auxiliary motor resulting in a single interruption of the kinematic chain at the final reduction. Said interruption is achieved by means of a friction clutch activated automatically by the reaction torque of the auxiliary motor of the bicycle preferably by means of inclined plane means. 2.
