HELLO FRIENDS 

I am back with other post in this post we are learn about
CNT. CNT means CONTINUOUSLY VARIABLE TRANSMISSION. there so many question ask the people it

Is CVT better than automatic transmission?
How long do CVT transmissions last?
What is the difference between automatic and CVT transmission?
Why is CVT hated?

there are so many question releated to CVT so in this article i am share answer of all of question. so read full article first of all we need to understand 

what is the CVT and how its work.

The most common type of CVT uses a V-belt which
runs between two variable diameter pulleys.

 The pulleys consist of two cone-shaped halves that
move together and apart.

The V-belt runs between these two-halves, so the effective
diameter of the pulley is dependent on the distance between the two-halves of
the pulley.

 

The V-shaped cross section of the belt causes it to ride
higher on one pulley and lower on the other; therefore the gear ratio is
adjusted by moving the two sheaves of one pulley closer together and the two
sheaves of the other pulley farther apart

 

As the distance between the pulleys and the length of the
belt does not change, both pulleys must be adjusted (one bigger, the other
smaller) simultaneously in order to maintain the proper amount of tension on
the belt.

 

Simple CVTs combining a centrifugal drive pulley with a
spring loaded driven pulley often use belt tension to effect the conforming
adjustments in the driven pulley.

 

The V-belt needs to be very stiff in the pulley’s axial
direction in order to make only short radial movements while sliding in and out
of the pulleys.

 

The pulley-radial thickness of the belt is a compromise
between maximum gear ratio and torque.

 

Steel reinforced v-belts are sufficient for low-mass
low-torque applications like utility vehicles and snowmobiles but higher mass
and torque applications such as automobiles require a chain.

Each element of the chain must have conical sides that fit
the pulley when the belt is running on the outermost radius.

As the chain moves into the pulleys the contact area gets
smaller. As the contact area is proportional to the number of elements, chain
belts require many very small elements.  

here in FAQs

1) Is CVT better than automatic transmission?

here first of all cvt is depend upon how the driver are actually driving their vehicle and the advantage of cvt is provide its ability to continuously change its gear ratio.  it means you are driving at top speed of your vehicle cvt is choose the best peak of your vehicle and provide the more efficiency of your engine when especially when driving in the city. 

2) What is the difference between automatic and CVT transmission?

One of the advantages of a CVT is its ability to continuously change its gear ratio. This means that no matter what the engine speed it, it is always performing at its peak efficiency. CVTs often offer better fuel economy as a result, especially when driving in the city.

the automobile technology says that most cars equipped with CVTs offer a smoother ride than a similar car with a regular automatic. This is because the transmission never shifts. There is no abrupt downshifting when the car needs additional power, and there is no feeling of gear hunting that you sometimes feel with a traditional automatic. 

A CVT is lighter than a traditional automatic, and this, combined with the smoother operation, helps to improve the fuel efficiency of vehicles that come equipped with a CVT.

Disadvantages of CVT

While the lack of upshifting and downshifting is considered an advantage of the CVT, some drivers miss the sensation of the vehicle moving through the shift points. If you prefer a sportier driving experience, then the lack of fixed gears makes the ride less engaging.

Another complaint that drivers tend to make about a CVT is the loud droning sound that occurs during acceleration. This happens because the CVT forces the engine to continuously run a constantly high rpm as it gets up to speed.

 As CAR driver explains, the general public has been less accepting of the CVT due to the difference in noise perception from mechanical or step automatic transmission.

CVTs can be expensive to repair or replace when compared to a conventional automatic transmission.

 i hope your doubt on cvt is clear now any doubt or request please comment below.
