The transmission includes gears through which the torque is transferred to the drive wheels from the engine. The transmission includes a clutch that ensures the absence or presence of a connection between the box and the motor, drive shafts. An integral part is the gearbox itself . Through it, the supply and redistribution of torque and power to the drive shafts from the engine is carried out.
Most of the technologies that are used in the tuning of the transmission, passed its test in motorsport. It should be said that the transmission of any, especially a sports car, is the most important way of translating the dynamic characteristics of the motor. A machine with a relatively weak engine can become quite fast if the gear ratios are correctly selected.
In sports cars, unsynchronized (cam) and synchronized boxes are used. Depending on the type of switching, they are divided into sequential (providing sequential selection) and ordinary (H-circuit).
For the implementation of a simple (normal) movement on the road, cam boxes are almost unsuitable. This is due to the fact that they emit a lot of noise and have a relatively small resource, and are also considered "hard" when shifting gears. In addition, their cost is incomparably higher than synchronized, and they need qualified and regular service.
Synchronized boxes differ from standard gearboxes. Their correct selection for the main pair of the input shaft, gearbox and driven gears in the secondary shaft ensures the coordinated operation of the entire transmission. The gear ratio is selected taking into account the moment and power characteristics of the motor. An important factor is the size of the wheels.
The gear ratio is the ratio of the number of teeth in the pinion gear to the number of teeth in the pinion gear. The higher it is, the faster the motor will twist the set speed. This will provide a faster set of speed. Along with this, the need arises for frequent switching. As a result of this, there will be some decrease in the maximum transmission speed.
There are several tools to increase the acceleration dynamics of the machine.
You can change the gear ratio in the main pair of the gearbox. For example, the tenth-generation VAZ front-wheel drive cars have, as a rule, standard numbers. So, in the production process, a gear ratio of from 3.7 to 3.9 is established. The exception is the VAZ 21103 (16V). Its gear ratio is 3.5. As practice shows, changing the main pair to 4.1 or 4.3 can turn the usual "eight" into a very dynamic car. Along with this, more often it is necessary to carry out gear shifting. But, along with this, with any maneuver and at a traffic light, the car is the first.
Speaking of gear shifting, one cannot but mention the special tuning series. If you unscrew the engine strongly enough on the first, then when switching to the second, the speed will drop sharply. This is mainly due to the too large difference between the gear ratios for the first and second gears. Tuning series contribute to a confident and uniform acceleration. In this case, the first gear is slightly reduced (relative to standard). The dynamics of this option is slightly deteriorating, but at the same time it becomes somewhat "longer." The second will be close to the first. This will save you from a noticeable “failure” that occurs in front-wheel drive VAZ cars. Third and fifth gears are the same as standard. The fourth is closer to the third, and the sixth to the fifth, respectively.
