Jatco CVT7 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.

Jatco CVT7 Movie

Introducing the features and the structure of "Jatco CVT7", the world's first CVT equipped with sub transmission. This section compares the CVT7 with previous CVT, and provides a detailed introduction to the new structure of the auxiliary gearbox system.

Features of Jatco CVT7

Features of Jatco CVT7

World's first*1 application of an auxiliary gearbox
World-leading level gear ratio 7.3)

Lower oil agitation resistance
Improved fuel economy by reducing friction by 30%

Smaller pulley
Down sizing and weight reduction by 13% realizes higher fuel efficiency.

Use of a low-rigidity lock-up damper
Improved fuel efficiency by the wider lock-up area

Use of a super-flat torque converter
Full length of the transmission 窶錀 cut by 10%

Use of high-efficiency oil pump
Improved fuel efficiency

Integration of a clutch and an auxiliary gearbox
Full length of the transmission 窶錀 cut by 10%

The world-leading level gear ratio coverage for enhanced quietness, and responsiveness on starting and acceleration

世界一の変速比幅で発進・加速性能と静粛性を向上

Reduced friction

フリクションの低減

Smaller and lighter

小型軽量化

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.
