CVT with an auxiliary gearbox for mini and small FWD vehicles
With its new-structure auxiliary transmission system, the new-generation CVT increases the gear ratio range, and friction-reduction technology and realizes enhanced fuel efficiency as well as great driving performance, aiming for significantly improved environmental performance as highly expected. Furthermore, the reduction in size and weight expands its applicability to a broader range of vehicles including mini-vehicles and small-sized vehicles.
World's first*1 application of an auxiliary gearboxWorld-leading level gear ratio 7.3)
Smaller pulleyDown sizing and weight reduction by 13% realizes higher fuel efficiency.
Use of a super-flat torque converterFull length of the transmission cut by 10%
Integration of a clutch and an auxiliary gearboxFull length of the transmission cut by 10%
Lower oil agitation resistanceImproved fuel economy by reducing friction by 30%
Use of a low-rigidity lock-up damperImproved fuel efficiency by the wider lock-up area
Use of high-efficiency oil pumpImproved fuel efficiency
The revolutionary-structure which combines of the belt CVT with an auxiliary transmission (two-step gear change) realizes the world-leading level gear ratio coverage, as well as enhanced responsiveness on starting and acceleration and improved quietness in high-speed driving.
Reduction in pulley size, oil agitation resistance, etc. realize friction cut by 30% compared with conventional CVTs of the same class.
The two-step gear change by an auxiliary transmission realizes smaller pulleys, reducing the overall length by 10% and weight by 13% compared with conventional CVTs of the same class.
