synopsis on continuous variable transmission



Continuous Variable Transmission 


In continuously variable transmission (CVT) infinite number of effective gear ratios changes from maximum to minimum values. The difference between other mechanical transmissions and continuously variable transmission (CVT) is few different distinct gear ratios to be selected. Better fuel economy can be achieved by enabling the engine to run at most effective revolutions per minute in continuously variable transmission (CVT) than other mechanical transmission systems.

A continuously Variable transmission (CVT) is a transmission which can gradually shift to any effective gear ratios between a set upper and lower limit. The almost infinite variability of a CVT allows the engine to maintain a constant speed while the vehicle increases in velocity. This can result in better vehicle performance if the CVT is shifted such that the engine is held at the RPM that it runs most efficiently at and/or produces the most power. Because there are no steps between effective gear ratios, CV T’s operate smoothly with no sudden jerks commonly experienced in manual transmission. Since drivers expect a car to jerk or the engine sound to change as they press the accelerator pedal further, it is very confusing for them when the car smoothly accelerates without the engine revving faster. Drivers have unfortunately perceived this as the car lacking power which is causing a marketing problem for the transmissions
Mainly the CVT has primary and secondary clutches which are connected by belt in which the Primary clutch is connected to the Ac motor and Secondary Clutch connected to the gear box and the power is transmitted from Primary clutch to the Secondary clutch by belt.

Primary and Secondary clutches are made of pulley’s. To have the required performance of the vehicle the speed of the engine has to be reduced in the CVT, this variation in the speed reduction can be achieved by changing the contact diameters of the belt on pulleys. In normal pulleys the diameter cannot be changed so to have change in the contact diameter between belt and pulley, the pulley used are different from the conventional pulleys.

Material Required:

  • V-Belt Pulley’s

  • Ac motor

  • Bearings

  • Nut Bolts

  • Shafts

  • Belt

  • Metallic Stand


For power transmission instead of gears we are using Two pulley’s connected by a belt. We are using AC motors on one side to drive the primary section of the Project. Primary Section includes Pulley with bearings connected to AC motor. Ac motors turn on the Primary pulley. The other one is connected to the rest of transmission to the wheels. The magic of CVT is that the size of the pulleys can change from small to large, and infinite sizes in between. So to start off with, the AC motor’s pulley will be small and the other one large, In this case the speed at the Secondary side of the project will low. As the Diameter of the Primary is about 20 mm and the diameter of the Secondary is about 42 mm which is very large. So the speed will be low at the secondary side of the CVT. Once the we change the diameter of the primary pulley, As we start increasing the diameter and take make it up to extreme level suppose 42 mm. In this case the diameter the secondary reduces about 20 mm. Now the speed of the Secondary pulley increases. Hence it starts delivering high amount of power transmission and RPM( revolution per minute).


Continuously variable transmissions (cvt) are praised for being able to deliver a smooth driving experience and improve fuel efficiency, with no fixed gear ratios. CVT is most suitable and easy way to transfer the power from one point to another. It is widely used in industries for power transmission.


  1. Money saving

  2. Time Saving

  3. Efficiency increasing

  4. More output in less time


After all the testing we are successful in representing our idea of the project in practical way. The project on which we are working is working with very ease and efficient way. We are able to transfer the variable power transmission from one mechanism to another.

  • GPS and GSM modem Study.

  • How can we send data as a SMS

  • 8051 based Project- it’s easy to work on it.


In this project we will make project using 89s51. In this project we will sense the accident and our system will automatically send SMS of location on our mobile no.Alcohol sensor will be uses for alcohol detection by driver or not. In this project we will use GPS to monitor current location. GSM modem to send SMS. Then sensor on that side will detect the car using Reed sensor. When sensor will get signal from car having magnet, then it will give signal to microcontroller 89s51. Microcontroller will display that station LCD connected with it. So wherever our robotic car will go our sensor will read it and Display ON . We will use 16*2 LCD for this purpose. We will connect REED sensor for car detection. We are using IC89s51 because we studying it in degree. We know about it. We will connect sensors on port 1 and LCD on port0. Register select pin of LCD on p2. 5, READ/WRITE on p2.4, Enable on p2.3. port 0 is open collector port so we will connect 10k register array with it.

We will use GSM modem SIM 300 it will work at 9600 baud rate

We will use GPS receiver GR 87 that works on baud rate 4800

Both will be connected serially with Microcontroller. Microcontroller is connected from serial port with MAX 232. And Max232 is connected with Both Module – GSM and GPS. There will LCD 16×2 which will show Latitude and longitude Coordinates. When any interrupt at pin 21 of Micornctroller then our system will send coordinates by message to particular saved no.

Look around. Notice the smart “intelligent” systems? Be it the T.V, washing machines, video games, telephones, automobiles, aero planes, power systems, or any application having a LED or a LCD as a user interface, the control is likely to be in the hands of a micro controller!

Measure and control, that’s where the micro controller is at its best.

Micro controllers are here to stay. Going by the current trend, it is obvious that micro controllers will be playing bigger and bigger roles in the different activities of our lives.

So where does this scenario leave us? Think about it……

The world of Micro controllers

What is the primary difference between a microprocessor and a micro controller? Unlike the microprocessor, the micro controller can be considered to be a true “Computer on a chip”.

In addition to the various features like the ALU, PC, SP and registers found on a microprocessor, the micro controller also incorporates features like the ROM, RAM, Ports, timers, clock circuits, counters, reset functions etc.

While the microprocessor is more a general-purpose device, used for read, write and calculations on data, the micro controller, in addition to the above functions also controls the environment.

We have used a whole lot of technical terms already! Don’t get worried about the meanings at this point. We shall understand these terms as we proceed further

For now just be aware of the fact, that all these terms literally mean what they say.

Bits and Bytes

Before starting on the 8051, here is a quick run through on the bits and bytes. The basic unit of data for a computer is a bit. Four bits make a nibble. Eight bits or two nibbles make a byte. Sixteen bits or four nibbles or two bytes make a word.

1024 bytes make a kilobyte or 1KB, and 1024 KB make a Mega Byte or 1MB.

Thus when we talk of an 8-bit register, we mean the register is capable of holding data of 8 bits only.

The 8051

The 8051 developed and launched in the early 80`s, is one of the most popular micro controller in use today. It has a reasonably large amount of built in ROM and RAM. In addition it has the ability to access external memory.

The generic term `8×51` is used to define the device. The value of x defining the kind of ROM, i.e. x=0, indicates none, x=3, indicates mask ROM, x=7, indicates EPROM and x=9 indicates EEPROM or Flash.

A note on ROM

The early 8051, namely the 8031 was designed without any ROM. This device could run only with external memory connected to it. Subsequent developments lead to the development of the PROM or the programmable ROM. This type had the disadvantage of being highly unreliable.

The next in line, was the EPROM or Erasable Programmable ROM. These devices used ultraviolet light erasable memory cells. Thus a program could be loaded, tested and erased using ultra violet rays. A new program could then be loaded again.

An improved EPROM was the EEPROM or the electrically erasable PROM. This does not require ultra violet rays, and memory can be cleared using circuits within the chip itself.

Finally there is the FLASH, which is an improvement over the EEPROM. While the terms EEPROM and flash are sometimes used interchangeably, the difference lies in the fact that flash erases the complete memory at one stroke, and not act on the individual cells. This results in reducing the time for erasure.

Understanding the basic features of the 8051 core

Let’s now move on to a practical example. We shall work on a simple practical application and using the example as a base, shall explore the various features of the 8051 microcontroller.

Consider an electric circuit as follows,


The positive side (+ve) of the battery is connected to one side of a switch. The other side of the switch is connected to a bulb or LED (Light Emitting Diode). The bulb is then connected to a resistor, and the other end of the resistor is connected to the negative (-ve) side of the battery.

When the switch is closed or ‘switched on’ the bulb glows. When the switch is open or ‘switched off’ the bulb goes off

If you are instructed to put the switch on and off every 30 seconds, how would you do it? Obviously you would keep looking at your watch and every time the second hand crosses 30 seconds you would keep turning the switch on and off.

Imagine if you had to do this action consistently for a full day. Do you think you would be able to do it? Now if you had to do this for a month, a year??

No way, you would say!

The next step would be, then to make it automatic. This is where we use the Microcontroller.

But if the action has to take place every 30 seconds, how will the microcontroller keep track of time?
