CVT++ gearbox (Requires participation in making the prototype)
The basis of CVT gearboxes
In general, the basis of the work of these types of gearboxes is based on friction. In simpler words, if two round plates are assembled facing each other and a roller is placed between these two plates, the rotational force of the first plate is transferred to the second plate by using the friction force between them, and by changing the positioning angle of the roller between the plates, a variable number of revolutions and torque is created.
Main advantages of CVT gearboxes
1- Not creating momentum when changing speed or torque;
2- Achieving changes in output speed and torque with very continuous coefficients;
3- High mechanical efficiency compared to old generation gearboxes;
4- Direct impact on reducing fuel (more than 17%) and energy consumption compared to automatic or gear transmissions;
5- economically more affordable;
6- Occupying less space than old generation gearboxes;
7- Very low time to respond to changes and produce less sound;
8- Very high compatibility with computer systems in terms of schedule allocation regarding performance.
Main disadvantages of CVT gearboxes
1- Production of limited torques compared to old generation gearboxes;
2- Higher construction cost due to the need for advanced technologies and more modern equipment, due to the complexities of production and construction;
3- Not having the ability to create instant accelerations, due to the work of these types of gearboxes based on friction;
4- The inability to receive high output power due to the lack of direct involvement of the constituent parts of these types of gearboxes;
5- The unwillingness of many automobile companies to use these gearboxes, due to the nature of their performance despite the many advantages;
6- More expensive maintenance system.
Solutions for solving the problems of CVT gearboxes
Some companies tend to use these types of gearboxes for many reasons. That's why they are looking for optimization and fixing the problems of these gearboxes. Newer models were designed and produced, which have a longer life than the old models. However, their work is still based on friction. An example is to use belts or chains instead of rollers because it is cheaper.

CVT++ gearboxes
Considering the many advantages of CVT gearboxes compared to conventional gearboxes, if the mentioned disadvantages are reduced or completely eliminated, the use of new generation gearboxes seems to be much more economical, especially in the automotive industry. For this reason, the newer and developed generation of CVT gearboxes called CVT++ can be a very suitable alternative. Gearboxes that can be designed and produced combining old and new generation gearboxes
Main advantages of CVT++ gearboxes
1- Direct involvement of equipment and internal parts of the complex with each other;
2- Higher efficiency compared to previous generation gearboxes due to frictionless performance;
3- 10% fuel consumption reduction in cars compared to previous generation gearboxes;
4- Having a longer service life;
5- Instantaneous acceleration in cars;
6- can be used in off-road vehicles;
7- Not creating momentum when changing speed or torque;
8- Achieving changes in output speed and torque with very continuous coefficients;
9- Very high compatibility with computer systems in terms of assigning a schedule regarding the operation;
10- Very low response time to changes;
11- Producing less sound;
12- Ability to use cheaper lubricants;
13- Lower maintenance cost.
