Transmission VAZ-2109 and its tuning
The VAZ-2109 gearbox is a complicatedThe technical mechanism, without which the machine can not advance and meter. At the moment there are many so-called "tuned" gearboxes, which have a modified filling and different gear ratios. However, not every transmission will be able to approach the driver under his specific driving style. Therefore, many craftsmen independently refine this detail with the help of special tools. In this article, we will look at how the transmission on the VAZ-2109 is being finalized.
Why is it necessary to increase the speed?
The main goal of our revision is an increaseddynamics of acceleration. And in order for the VAZ to fly along the roads, it is necessary at least to increase the engine's rotational speed, that is, to make the arrow of the tachometer to be at the maximum maximum values. In principle, it is not difficult to improve the dynamic characteristics - it is enough simply to refine transmission ratios (as will be done, we will consider below). It is best to make the difference between them extremely small. Then, when switching stages from a lowered to an increased gearbox, the VAZ-2109 will not severely curtail engine speed - they will remain practically at the same level. Due to this, the motor will again have an optimal torque, which, in turn, contributes to rapid acceleration of the machine.
Of course, the developers themselves "nine" accounted forthese are all the moments when constructing the checkpoint, but still not very ideal units came off the assembly line. Such gearbox VAZ-2109 had large slips between neighboring gears. The most important defect, which was noted by motorists, is the increased wear of the synchronizer of the 2nd stage.
- The first transfer is 4.33.
- The second is 4.5.
- The third step is 4.7.
- The fourth is up to 5.0.
- And the fifth can reach the mark to 5.125.
In this case, do not forget that the "nine"is a front-wheel drive car, and its differential is in the transmission itself. This arrangement of the part contributes to reduced tire wear and better maneuverability. And if you install such "pairs" in a box, there will be neither one nor the other. Therefore, in order to avoid unpleasant consequences, it is necessary to replace the differential from the standard one to the self-locking one. Then the car will be not only powerful, but also maneuverable, and about repair of the gearbox VAZ-2109 can be forgotten for the next few years.
What do we get as a result?
After finalizing the gear ratios, you can getA fast car that can be operated not only on the road, but also in the city. Perhaps the only drawback of such tuning is that the VAZ-2109 gearbox will not develop the car to the passport "max.". Although many car owners are satisfied with such a change in gear ratios, as the acceleration of VAZ is comparable with any sports car. And this is a serious indicator.
