A belt (or chain) connects The 2 pulleys, which often can change their diameters to provide an infinite amount of equipment ratios. Without any gears, the stepless transmission allows for smoother acceleration and effectiveness, though becoming more compact in size when compared to transmissions that do have gears. This is the very good set of properties for Daihatsu, because it allows for greater packaging in its kei and compact cars. But you can find downsides to a standard CVT
Inside of a hydrostatic CVT, the effective "gear ratio" is assorted by different helpful displacement from the pump, which will vary the quantity of oil delivered to the motor(s) at a supplied engine pace (RPM).
