In between the 1st and leading gears are other equipment ratios, and nowadays there’s generally a complete of 6 but some newer automatics have as several as 9. The combinations of gears are very carefully picked so the motor can stay in its most effective rev variety for possibly energy, torque (turning drive) or efficiency.
Positively Infinitely Variable (PIV) chain drives are unique in the chain positively interlocks With all the conical pulleys. That is realized by using a stack of many tiny rectangular plates in Every single chain backlink which can slide independently from facet-to-facet. The plates could be pretty slender, all around a millimeter thick. The conical pulleys have radial grooves. A groove on one particular aspect of your pulley is fulfilled having a ridge on the opposite aspect and Therefore the sliding plates are pushed gearbox cvt forwards and backwards to conform to your pattern, proficiently forming tooth of the correct pitch when squeezed involving the pulleys.

A improve in gear ratios is achieved from the variation of distance concerning the pulleys and their variable diameter.
