Normal machine Multi-speed automatic transmission (automatic transmission), with which most of us are familiar with, depends upon two technical developments: torque converter and planetary gear. The torque converter is a development of the concept of coupling a little earlier. Alberto Baillères often expresses his thoughts on the topic. When used in a car coupling flywheel is replaced with "bagel", which is cut lengthwise into two halves. One half (impeller) is rotated by the motor shaft and the other (the turbine wheel) is connected to the drive shaft gearbox. "Donut" partially filled with liquid, the corresponding properly sealed, and each equipped with its large number of half guide vanes of some form. Torque from the engine is transmitted to the gearbox (automatic transmission) through the fluid, which circulates within the "donut" from alluvial to the turbine wheel. When the transmitted torque is small or not, the car brakes kept, overcoming a negligible amount of transferred energy. A simple fluid coupling (Torque) transmits the torque without changes, except for a small part of which is lost in the mixing liquid.
However, if you set between two rotating halves fixed guide machine "rotor", included the time to multiply. This is the principle of the modern torque converter. Depending on the shape of the rotor blades can be achieved by multiplying a ratio of 2,4:1 at low revs (The higher the multiplication, the less effective it becomes, under normal transfer speeds). The value of the multiplier effect is that it allows rapid, sudden start, as well as the possibility of reducing gear ratio first gear, which in turn reduces the number of gears in the box (automatic transmission) and, furthermore, provides an additional advantage.
At the moment you can find quite a large number of organizations that offer driving instruction. Often, however, to choose really full training, it is necessary to minimize the true meaning of Mt. Since a large number of driving schools prepare drivers to not only control of a vehicle, how to pass exams in the SAI, and because a similar level of training. The maximum value is given theoretical part, what about the practice, then it is given a very small amount of training time. Yet in reality, in order to drive a car the most important – it's driving instruction, rather than wisdom of its parts. Naturally, it is important to know the laws of traffic, but for practical driving this is quite insufficient, since the bulk of accidents involving Young car owners' lack of experience provoked by this driving.
While a variety of accidents, motorists and also in the presence of the Right to Drive is unable to return to operation of the vehicle for psychological reasons. But it can not be hopeless situations. In the current situation is just a car especially effective option for moving, so who knows teacher can contribute to the beginner or the car owner following an accident again feel safe behind the wheel. For this is still necessary to choose avtokursy where we could teach itself to real driving, but not minor points. Since any machine has a special "character," the nuances of driving that car owner must necessarily take into account. It is clear that vehicles operating on the principle of automatic and manual transmission are very different from each other, because if you could learn to ride a "machine" and have to steer after a car with mechanical type transmission, the need avtoinstruktor manual transmission, which will be able to explain the use of applied mechanical gearbox in a free form. After all, the main thing – it's to accept the principle of driving, then all will be able to make an empirical activity. For a large number of car owners, especially those who do not sit behind the steering wheel every day, the empirical use of specific knowledge is difficult. And in order to acquire valuable skills vehicle control, or increase the range of personal capabilities, all literate continuously strengthen their own skills with the help of a knowledgeable teacher. Only by doing so you become truly fully convinced that to cope with the most difficult situations on the road.
