JATCO CVT 7
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.
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.
The world-leading level gear ratio coverage for enhanced quietness, and responsiveness on starting and acceleration.
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 CVT´s of the same class.
Smaller and lighter
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 CVT´s of the same class.
Characteristics of JATCO CVT7 W/R
Ratio coverage of 8.7 realizes high fuel performance
Expands the use range of the highest efficiency ratio based on the CVT7 to improve both mode and actual fuel efficiency.
Pursuit of outstanding drivability
Controls excessive increase in engine rotation and acceleration at engine start by locking up after engine start.
