Another transmission article on another version of the CVT transmission — the toroidal CVT system — replaces the belts and pulleys with discs and power rollers. Although such a system seems drastically different, all of the components are analogous to a belt-and-pulley system and lead to the same results — a continuously variable transmission. Here’s how [...]

More on CVT transmissions from: Part-2 of CVT transmissions. Pulley-based CVT Look into a planetary style automatic transmission, and you’ll see a complex world of gears, brakes, clutches and governing devices. By comparison, a continuously variable transmission is a study in simplicity. Most CVTs only have three basic components: A high-power metal or rubber belt A variable-input “driving” pulley An [...]
