Abstract
A drivetrain for connection between the output of a prime mover and the input of a final drive is described herein. The drivetrain comprises a CVT including an input connected to the output of the prime mover and an output; a power mixer having a first input connected to the output of the prime mover, a second input coupled to the output disk of the CVT and an output; a three-speed transmission having an input connected to the output of the power mixer and an output connected to the input of the final drive.
Claims15
A drivetrain for connection between the output of a prime mover and the input of a final drive;
- the drivetrain comprising:
- a CVT including an input connected to the output of the prime mover and an output;
- a transmission having an input connected to the output of the CVT and an output connectable to the input of the final drive;
- the transmission including first and second cascading selection mechanisms provided between the input of the transmission and the input of the final drive;
- wherein the first and second cascading selection mechanisms are so configured and controlled that the position of the second selection mechanism can be changed by the controller depending on the next desirable configuration.

A drivetrain for connection to the output of a prime mover and to the input of a final drive therebetween;
- the drivetrain comprising:
- a CVT including an input coupled to the output of the prime mover and an output;
- the CVT being so configured as to provide, between the input and output thereof, a primary continuous range of gear ratios;
- a transmission including:
- a first selection mechanism including an input connected to the output of the CVT and first and second outputs;
- a first gear train connected between the first output of the first selection mechanism and the input of the final drive, the first gear train being so configured as to selectively provide, in cooperation with the CVT, a first secondary continuous gear ratio between the output of the prime mover and the input of the final drive;
- a second selection mechanism including first and second inputs and an output connected to the final drive;
- a second gear train connected between the second output of the first selection mechanism and the first input of the second selection mechanism, the second gear train being so configured as to selectively provide, in cooperation with the CVT, a second secondary continuous gear ratio between the output of the prime mover and the input of the final drive;
- and
- a third gear train connected between the second output of the first selection mechanism and the second input of the second selection mechanism, the third gear train being so configured as to selectively provide, in cooperation with the CVT, a third secondary continuous gear ratio between the output of the prime mover and the input of the final drive.
