Administrator posted this 2 weeks ago

Manual, hydraulic, automatic, variable and robotic transmission. Buying a car, the driver always draws on the type of transmission installed and a number of its other features. Quite common gearbox is CVT transmission, its main advantages and disadvantages and will be discussed.

CVT - is a stepless gearbox, the peculiarity of which is that the usual in the understanding of the classical transmission automatic transmission is absent in this case. A car with a CVT is more evenly and smoothly gaining speed while the efficiency increases slightly. Switching stages is due to the software component, while the driver will be able to switch to manual control when driving on dirt or snow.

How does the manual control in the CVT work? Manual control mode in this type of gearbox is provided by the program of the ECU and in manual mode begins to work on the algorithm of inclusion of pre-programmed fixed gear ratios

The CVT has several types of structure, but the most common is the wedge.

The advantages of the CVT in your car:

  • Smooth and dynamic acceleration (in comparison with automatic transmission and rkpp)

  • Reduced fuel consumption

  • No shocks when changing gears

  • Efficiency in comparison with automatic transmission is higher by 5%

  • Easy control

  • Efficient use of engine power and torque

Сons of a car with a CVT:

  • Complex system management, and configuration of powertrain electronics

  • The care variable is also costly (e.g., motor oil and only high premium)

  • The CVT is not suitable (not desirable) for sports cars and powerful cars in General. It is not recommended to put on a very powerful machine
