Abstract
A multiple-regime continuously variable ratio transmission system has a system input shaft (I), a system output shaft () and a continuously variable ratio transmission unit (variator) connected to the system input shaft and having a variator output shaft. A first mixing epicyclec gear train (P) having inputs drivably connected to the variator output shaft (V) and the system input shaft via a first clutch (H) and a second mixing epicyclic gear train having inputs drivably connected to the variator output shaft and the system input shaft has an output () connected to a third epicyclic gear train (E) having an output which is selectively connectable to the to the system output shaft via a first braking element (L). A second braking element (B) is adapted to lock the output () of the second mixing epicyclic gear train in a stationary position.
