Positively Infinitely Variable (PIV) chain drives are distinctive in that the chain positively interlocks Along with the conical pulleys. This is attained by using a stack of numerous little rectangular plates in each chain website link which will slide independently from facet-to-side. The plates might be pretty skinny, all-around a millimeter thick. The conical pulleys have radial grooves. A groove on one particular facet from the pulley is fulfilled using a ridge read here on one other facet and Therefore the sliding plates are pushed forwards and backwards to conform for the sample, efficiently forming teeth of the right pitch when squeezed in between the pulleys.
Welcome to aspect 3 of our deep dive collection to the Perodua Ativa (also called the D55L), where by the focus this time is to the transmission which will be utilized by the compact B-phase SUV. UPDATE: We’ve driven The brand new Perodua Ativa! Browse our very first impressions critique here.
