Transmission arrangement comprising a power mixing mechanism

摘要

A transmission arrangement for transmitting power from a power source to an electrical generator. The transmission arrangement comprises a continuously variable transmission (CVT) and an alternative transmission that is more efficient at transmitting power than the CVT. The transmission arrangement further comprises a power mixing mechanism for combining power from the CVT and the alternative transmission into a combined power output to be provided to the electrical generator. The percentage of CVT power within the combined power output decreases as the power supplied by the power source increases.

1. A transmission arrangement for transmitting power from a prime mover having a controllable variable output to an output shaft associated with an input shaft of an electrical generator, the transmission arrangement comprising:
a continuously variable transmission (CVT) so configured as to receive power from the variable output of the prime mover and to provide a CVT power output; the CVT having a variable transmission ratio; an alternative transmission so configured as to receive power from the variable output of the prime mover and to provide an alternative transmission power output; and a power mixing mechanism so configured as to combine the CVT power output and the alternative transmission power output into a combined power output to be supplied to the output shaft; an electronic controller so configured as to adjust the transmission ratio of the CVT in response to a change in a load demand at the electrical generator; the adjustment of the transmission ratio of the CVT causes an adjustment in the percentage of CVT power within the combined power output; wherein a percentage of CVT power within the combined power output decreases as power supplied by the prime mover increases.
