The car modified knowledge- CVT gearbox works

The automatic transmission fuel consumption and high power weak already well known fact that in order to solve this problem, engineers have tried various methods. For example, the economic model for automatic transmission design, the state of the economic model, the computer-controlled transmission at lower engine speeds, complete the shift to reduce the power output of the engine, so as to achieve the purpose of fuel; same applies to automatic transmission design movement patterns so in the high-speed transmission, the engine desperately to squeeze every drop of power of the engine to improve vehicle dynamic performance. But these are not fundamentally resolve the problem of the automatic transmission of high-power and low-power.

    Because no matter which kind of mode is bound to the will power and fuel consumption in a compromise. So, how can a fundamental solution to this contradiction? Just been born in the 1980s, automatic transmission, or impossible, has now become a reality, the power and economy even more than the manual transmission. What institutions so magical? , CVT continuously variable transmission technology.

 Called CVT, as the name implies, is linear in certain transmission ratio range adjustment drive than theoretically equivalent countless stalls. Its structure is very simple, consisting of two conical disc and a steel chain. Conical disc is the two conical disc combined together to form a disk drive with a V-groove.

The conical disc axially mobile, under the thrust action of the hydraulic the extrusion just the width of the sheet chain in order to adjust the V-shaped groove. When the conical disc is moved inwardly, the steel chain to the center of a circle other than the direction (centrifugal direction) the extrusion of the cone disc movement. Thus, the steel chain driven disc diameter increases, the transmission ratio will change.
  Therefore, no governor can be achieved. Some people may ask, alone just a piece of the chain with the V-groove friction with the move weighs a ton more than the car? In fact, the core technology of the car using the CVT in a steel chain. It is not an ordinary chain. It is the combination of the driving belt by the many special shape of a small steel.
