Abstract
A continuously variable transmission for vehicles, in which the power from a prime mover is divided by a power dividing mechanism and transmitted to a hydraulic continuously variable transmission (HCVT) apparatus and to a mechanical transmitting means for mechanical transmission of power, and the power from the HCVT apparatus and the mechanical transmitting means is collected and selectively outputted for satisfying both the maximum speed performance and the fuel consumption performance of the vehicle. A lock-up brake in the power dividing mechanism stops the rotation of the hydraulic pump of the HCVT so that the power from the input member may be mechanically transmitted to the mechanical transmitting means only via the power dividing mechanism to achieve a minimum gear ratio. A lock-up clutch directly connects the input member and the mechanical transmitting means so that the power from the input member may be directly and mechanically transmitted to the mechanical transmitting means to achieve a greater gear ratio than the minimum reduction ratio.
