[3] The V-belt needs to be incredibly stiff during the pulley's axial route to make only small radial movements though sliding in and out of your pulleys.
on the end is like expressing “ATM machine.” (Enable’s just get in touch with them CVTs from now on.) They run in a different way from traditional geared transmissions, which use quite a few sets of gears to improve acceleration and performance determined by what the driver would like.
