A continuously-variable-ratio transmission (CVT), capable of geared neutral and of operating in at least two regimes and including a ratio-varying component(4), a power-recirculating epicyclic (E), a final drive shaft (1) connectable with the variator by way of one of two alternative driven shafts (A, B) and an input epicyclic (e) the input of which is connectable to a prime mover (3) and the two outputs of which are connected to the two shafts (A, B) respectively. The power-recirculating epicyclic (E) is associated with clutches (44, 46) whereby power is recirculated through it in that regime. In the remaining one or more regimes no power is recirculated. |
