CVT
Main features
- bidirectional non-clutched
- precise electronic control
- robust design
Advantages
- no necessity for service and spare parts like oil or belts
- high torque on stalled wheel
- suitable for harsh environments
Structure
The CVT consists of two transmissions. The first transmission has variable ratio and utilizes V belt. Proprietary mechanical design allows to prevent belt friction. Gear ratio is electronically controlled via brushed motor, which allows to switch the gear ratio from min to max in about 2 seconds.
The second transmission has fixed ratio and uses toothed belt. The tension can be easily adjusted with a car key. The output shaft is equipped with tachometer, which is used to estimate the wheel speed and the current gear ratio. The CVT is ready to use in application with IntEn.
