The ease of CVT - a CVT is easy to drive with as it's the same as any automatic transmission. Score: 5/5 (9 votes) . Rather it is built on twin pulleys connected to the car's engine and the wheels. What does a slipping transmission feel like? For example, when the pitch radius is small on the driving pulley and large on the driven pulley, then the rotational speed of the driven pulley decreases, resulting in a lower gear. When the pitch radius is large on the driving pulley and small on the driven pulley, then the rotational speed of the driven pulley increases, resulting in a higher gear. Thus, in theory, a CVT has an infinite number of "gears" that it can run through at any time, at any engine or vehicle speed. When the cones are close together (when the diameter decreases), the belt rides higher in the groove, and the radius of the belt loop going around the pulley gets larger. There is no "gear hunting," because the CVT cycles steplessly down to a gear ratio appropriate for the driving conditions. A CVT (continuously variable transmission) is a type of automatic transmission that has an indefinite number of gear ratios. Thanks Dave and Zafar.
