Under the exact scenario, a CVT can almost immediately find the exact gear ratio, thus providing seamless power. In addition, a traditional automatic transmission normally struggles while the vehicle is under heavy load. Remember that torque is a measure of how much force is required to cause an object to rotate.Ī CVT also eliminates gear hunting as the vehicle decelerates, such as when it is going up a hill. This allows for a smoother operation and quicker drive.Īnother advantage of CVT is that it allows the engine to rev almost immediately, thus delivering maximum torque. On the other hand, CVT varies gear ratio continuously and seamlessly rather than in a stepped manner. Shifting between the ratios can create shift shocks or sudden jerks.

Nonetheless, this compact design makes CVT an ideal transmission choice for compact vehicles.īoth traditional automatic transmission and manual transmission use different physical gears to go through different gear ratios in a step-by-step fashion. The design and components are considerably simpler. Remember that there are no physical gears or a set of planetary gears inside a typical CVT box. One advantage of CVT is that it is lighter and simpler as compared to traditional automatic transmission and manual transmission. Pros of CVT: Advantages of Continuously Variable Transmission 1. These components are analogous to a belt-and-pulley system nonetheless. For example, toroidal CVTs are made of discs and power rollers. Other versions of CVT are not made of belts and pulleys. These interactions between the two pulleys allow an almost infinite number of gear ratios. On the other hand, when the radius is large on a driving pulley and small on a driven pulley, the result is a higher gear. The relative changes between the radii of these two pulleys create an infinite number of gear ratios.Ī driving pulley with a small radius and a driven pulley with a larger radius correspond to a lower gear.

When one pulley increases its radius, the other decreases the radius to keep the connecting belt tight. The driving pulley is essentially where the energy from the engine enters the transmission while the driven pulley transfers the energy to the driveshaft.īoth the driving and driven pulleys are made of two movable plates that can be moved closer or farther apart, thus increasing or decreasing the radius of each pulley. This belt also allows the transmission of mechanical energy between the two pulleys. Within a CVT is a rubber or metal-link belt that connects two pulleys-an input or “driving” pulley and an output or “driven” pulley.
