Intro: Continuous variable transmission which ensures a smooth driving experience it provides a infinite number of gear ratios making gear change operation

Inner working of CVT including reverse gear ?
Two conical pulleys and a steel belt makeup a basic CVT the input pulley turns the belt and the belt turns output pulley the gap between the cones determined
the effectiveness diameters of the pulleys for this configuration the output speed will be less than

input speed
Under drive
Doubt >Din
As gaps decreases the effective diameter of the pulley increases that’s the simple mechanism of basic operation of CVT
Now we see what happens to the arrangement when right side cone of the input is moved to the right and left cone of output is moved to the right
the gaps are reverse of previous case this means the effective diameter of pulley is also reverse and hence we will get an overdrive the transmission
control unit will adjust the width between these cones as a result any other kind of transmission the speed change will smooth and unnoticeable
How a reverse gear is even possible with this mechanism :::::
In order to achieve forward and reverse gear ratios planetary set arrangements is used in CVT first look at gear mechanism then move to reverse gear the
input shaft connected to sun gear carrier or planetary set is fitted with the input pulley this means the output of planetary set is drawn from carrier if ring
gear is also turned at the input speed the carrier will rotate at input speed as well this possible by connecting the sun gear with ring gear a clutch pack used for
this purpose if clutch pack is well pressed the frictional force between the plates will lock the sun gear to the ring gear this how forward gear is achieved whole
mechanism is moves as single unit now keep the gear stationary with second clutch pack the result is quite different the stationary ring gear will force the output
carrier to turn in reverse direction so does the input pulley to achieve reverse just released the first clutch and engage the second clutch the CVT offers a variety of
gear ratios for the reverse gear also even though it is not programmed to do so.
