In this article we will look at a topic such as stepless variator.Briefly describe the principle of its operation, the main differences, advantages and disadvantages.But above all, pay attention to the history of the origin of this whole system, to understand where this transmission came in the automotive industry, and who uses it mainly.
little history lesson
Start a patent for a continuously variable CVT, which is, in fact, was the first in the world, appeared in 1886.Its operation was extremely simple: the drive function in the transmission carried a leather belt, which is clamped between the two pulleys.An interesting fact is that this patent was developed in the Renaissance, the creator of the famous Leonardo da Vinci.However, to implement it in practice people can only a few centuries later.Progress does not stand still, and soon began to function stepless variator with a rubber strap.The first car, who worked on a similar principle was "Volvo 360", released in the late 80s.And even after a dozen years in the continuously variable transmission have already become used typesetting steel belts.
principle of transmission
Now consider how this works is the stepless variator.Reviews of car owners with a similar control system say that it has something in common with the automatic transmission.However, speaking from the point of view of mechanics, the total of these two systems, only the word "automatically".By this is meant not that the driver manually switches the transmission speed, while the task executes the vehicle electronics and hydraulics.This principle of operation can be compared with the bike.It gears connected chain, begin to rotate faster at the time when you start to pedal harder.In the passenger compartment stepless variator nothing remarkable no different from the usual "automatic machine".It has a selector with indicators PNRD, located under the steering wheel and two pedals - gas, brake.However, all the programs on the machine, which are switched depending on the characteristics of the motor, start with the first and finish 6th.In this case the number of transmissions, which are included by themselves almost indefinitely.
advantages and features of the transmission
When you are inside the car equipped with a continuously variable transmission, the sense of drive, jerks, which are possible in the process of driving is lost.You feel only a smooth ride in the first place because in the process of activation of motor processes involved a minimum of parts.Only two blocks are rotating pulleys that are inside the box, and a belt spanned therebetween.Incidentally, the last part is automatically changes its position depending on the speed of movement of the car.
On many modern machines can be set stepless variator."Toyota", "Nissan", "Volvo" - some brands, among which you can choose the model is such an economical and comfortable control system.
