Abstract

A drive transmission (2010) comprising a finite continuously variable transmission (FVT) (2021) having an input element (2020) and an output element (2026) and in which the ratio of the rotational speed of the input element (2020) to that of the output element (2026) is continuously variable over a finite range and a controllable differential (CD) (2500) having first (2102), second (2104) and third (2101) elements and wherein the second element (2104) of the CD (2500) is connectable to an output member (2012) of the drive transmission (2010), the input element (2020) of the FVT (2021) and the first element (2102) of the CD (2500) are connected to an input member (2013) of the drive transmission (2010) and the output element (2026) of the FVT (2021) is connected to the third element (2021) of the CD (2500).
