    Research output: Contribution to journalArticle


    Authors have been developing single-cavity half-toroidal-type CVTs, continuously variable power transmissions, for the past 14 years and recently have designed a new type of double cavity CVT for a 4 wheel drive automotive power transmission. This CVT easily distributes transmitting torque between front and rear axles without center differential gears. This report presents the configuration of the CVT of nominal input torque capacity 250 N-m and maximum speed ratio 1 : 8.7, and shows the power transmission efficiency.
