What is a CVT Transmission and How It Works?

A CVT transmission is also known as Continuously Variable Transmission which changes through an unending range of gear ratios seamlessly while driving. It is quite different from other kinds of transmissions. While the vehicle moves at varying speeds, the flexibility of a CVT allows the engine to operate at a constant RPM.

To understand how it works and the benefits offered, it is important to understand what exactly a CVT transmission is in your car!

What is a CVT Transmission?

The CVT transmission is commonly used in automobiles, snowmobiles, motor scooters, earthmoving machinery and tractors. This type of transmission has gained a lot of popularity recently.  However, it was initially designed by Leonardo DaVinci in 1490. Later it was patented by Daimler and Benz in 1886.

How Does a CVT Transmission work?

The CVT is an automatic transmission that requires two pulleys and a steel belt running between them. To keep up with the gear ratio, the CVT adjusts the diameter of the driver pulley. This transmits torque from the engine by transferring torque to the wheels.

A traditional transmission uses a large variety of intricate parts to work a range of preset gears, but a CVT system works through a pulley system. To work efficiently, the CVT system consists of cones that connect the pulley with a chain belt.

The width of the pulley totally depends on how much power is needed by the vehicle. If one pulley is larger, the other one tends to get smaller. As both the pulleys are not fixed, there are numerous gear ratios provided so that you can set the number of gears by yourself.

However, every CVT transmission is created differently. The most common one is pulley based but another popular type is Toroidal CVT. It uses rotating discs along with the power rollers to deliver the same result just like pulleys. To control the fluid flow, hydrostatic CVT is used. It produces a rotational motion. If any problem occurs related to your CVT transmission, make sure to look for a gearbox repair service.

Benefits of a CVT Transmission

There are a lot of benefits associated with a CVT transmission that could help you drive safely and efficiently. Here are some of the reasons why you should have a CVT transmission car!

• The biggest advantage of a CVT transmission is that it has the ability to continuously change its gear ratio as per the need. It means that no matter what the speed is, your car will always work efficiently. CVTs are meant to maintain fuel economy, especially when driving within the city.
• A CVT transmission weighs lighter than an automatic transmission. If compared to the smoother operation, a CVT will improve the fuel efficiency of your car.
• Since there is a lack of gearing, it is much easier for cars with CVT to maintain an ideal torque ratio for better working. These cars are meant to climb difficult terrains easily due to their variable transmission.
• Cars loaded with a CVT transmission have lower production costs as they have fewer moving parts than any traditional automatic transmission vehicle. This is why it is one of the leading reasons why you should prefer CVTs in comparison to an automatic transmission car.
• As you do not have to keep on switching between gears, a CVT transmission car offers a smooth ride.

FAQs:

How long will a CVT transmission last?

The CVT transmission has a life expectancy of at least 100,000 miles. A lot of car models can even last up to 300,000 miles. Just like a traditional automatic transmission, CVT transmissions are designed smartly to last your car’s full life.

Should you avoid buying a car with CVT transmission?

You need not worry if you own a car with a CVT. It is important to maintain your vehicle to expand its life expectancy. Many car models come with a CVT but forget to explain to the customers the way to look after it.

How often do you need to service a CVT transmission?

It is preferred to service a CVT transmission every 30,000 miles. Even though it can last up to 100,000 miles, you still need to get it inspected by a professional.

When should you change your CVT oil?

As per the manufacturer manual shared with you along with the following, make sure you change the CVT oil. This will help in increasing the efficiency of a CVT transmission.

Bottom Line

A CVT transmission car is quite fuel-efficient as well as offering a smooth ride, it is easier to drive on difficult terrain. Maintaining it as per the manufacturer manual, you can increase the life expectancy of your vehicle as well as the CVT transmission. It is important to understand what your car wants and needs to last it longer.
