The CVT tapered pulley is also called a transmission pulley. In fact, some technical changes have occurred. The initial contact surface of the pulley is not smooth enough, causing premature wear of the belt. Then a mirror treatment process is performed to increase the smoothness of the belt and reduce friction. In fact, If you look at the trajectory of it, it's more like squeezing and sliding. Rather than constantly driving the belt on a flat surface, one thing to understand is that the CVT drive tapered pulley is not smooth. Although it looks smooth and has a polished surface, this is only what we see with the naked eye, or what we imagine, In fact, after the surface of the tapered pulley used in CVT is mirror-finished, the surface will be damaged. That is, some texture will be added to the smooth tapered surface later (similar to the texture of a honing machine on the cylinder liner)! The CVT gearbox is designed with a complete automatic control system to prevent slid…
