V-pulley for a continuously variable transmission

摘要

A V-pulley is adapted for a continuously variable transmission which uses a chain belt composed of a plurality of chain blocks connected in its longitudinal direction, and a pair of V-pulleys operatively connected to each other through the chain belt. The V-pulley comprises a pair of conical pulley faces that the chain belt contacts, each of which is provided with a rough surface and a combination pattern of abrasion-prone and abrasion-resistant sections alternatively arranged at intervals shorter than the contact length and width of each chain block.
