Advantages and disadvantages of CVT gearbox - a problem that Vietnamese customers often worry about

CVT gearboxes have a simpler structure than other types of gearboxes.

Instead of using gears, CVTs use metal belts and pulleys to drive. Conventional transmissions have gears, but CVTs have no gears at all or manufacturers can set virtual gears for the vehicle. Along with many advantages, this type of transmission also has imperfections when compared to manual transmissions or dual-clutch automatics.

Advantage

The first advantage is optimizing the generated kinetic energy. With a CVT, the vehicle always operates in the correct gear ratio. Unlike an automatic or manual transmission, the CVT is programmed to keep the engine speed consistent with the generated kinetic energy.

According toAuto guide, CVT gearbox helps the car consume less fuel than other types of gearboxes. In theory, the CVT gearbox always puts the engine in a state suitable for the generated kinetic energy, thereby minimizing fuel consumption.

Especially when moving on the highway at a stable speed, the CVT gearbox will be effective, helping the car save fuel significantly.

The structure of a CVT is simple. Compared to traditional transmissions, CVTs have fewer parts. Instead of using a complex gear system, this transmission uses a series of conical pulleys connected to a belt.

Depending on the speed of the vehicle, the pulley will change position, providing different gear ratios. The operating mechanism of the CVT gearbox brings higher efficiency.

Due to their simple structure, CVTs are often lighter and smaller than conventional automatic transmissions. This also reduces the overall weight of the vehicle. For automakers, keeping vehicle weight to an optimal level is very important.

In addition, the shifting process of a CVT is much smoother than that of a gear-based transmission. A CVT does not cause jerky shifts like traditional transmissions.

Disadvantages

One thing that many people mention when using a car equipped with a CVT gearbox is the noise when operating at high rpm. This is a common disadvantage of CVT gearboxes, even if they are set up to simulate gears.

Another controversial issue when using CVT gearbox is that the feeling of driving the car is not interesting, not providing a sporty driving experience.

In exchange for convenience and fuel efficiency, users will have to sacrifice the exciting driving experience found with other types of transmissions.

Some CVTs are set up to feel like they are malfunctioning or broken. CVTs often don't feel like they are shifting gears, so a novice may be surprised and think the transmission is broken.

In addition, the maintenance, servicing and replacement costs of CVT gearboxes are more expensive, because the parts of this gearbox cost more than the rest.

CVT transmission repair requires experts who really understand the structure, while manual transmission and other types of automatic transmission repairmen are easier to find.
