It is necessary for variable diameter pulleys to be in pairs. The drive pulley is the one connected to the engine’s crankshaft.  This pulley is also known as the input pulley. It is called so because of how it transmits energy from the vehicle’s engine into the transmission.

The other pulley is referred to as the driven pulley because it is controlled by the drive/driving pulley. The driven pulley is an output pulley and its job is to send energy towards the driveshaft.

When the pulleys are far from each other, the belt rides at a lower level, thereby decreasing the pitch radius. The exact opposite occurs when the pulleys come close.

The ratio between the driven pulley’s pitch radius and the driving pulley’s pitch radius is what determines gear engagement.

In order to keep the belt tensed, one pulley boosts its radius, while the other reduces it. When the pulleys keep alternating ratios, we get various gear ratios. In fact, there are an endless number of gear ratios created.  So, a CVT is capable of producing all kinds of gears.

The simplicity of CVTs is what makes them a great transmission option and with new materials, CVTs are constantly improving in efficiency and reliability.
