When buying a car, most motorists already clearly know what they will choose - a car with a manual transmission or with an automatic transmission. But many at the same time are faced with difficulty when choosing between "automatic" and "variator". It can be very difficult for an untrained buyer to understand between these options. But there are several principles by which you can easily distinguish an automatic machine from a variator and make the right decision when buying a car.
Instructions
Step 1
Understand, for a start, the fundamental differences in the device of a conventional automatic transmission and a variator. The main component of a classic automatic transmission is the torque converter, which necessarily matches the clutch of a conventional manual transmission and is responsible for gear shifting. It is worth noting that he always does this in a timely manner, therefore, reduces engine wear. The variator is a variation of automatic transmissions, but it does not have fixed gears. The variator has no gear, it just smoothly and without interruption changes the gear ratio. Such a box has no jolts when starting off and during acceleration, like an automatic box.
Step 2
Remember that CVTs are equipped with an infinite number of gears, so that the engine performs its work in the most favorable modes. Consequently, CVTs have a high fuel efficiency that matches perfectly with average dynamics. Variators are completely different, but the best and most common is the V-belt variator with a variable diameter pulley. Also, a special transmission fluid is used for the variator, which must be changed every 100 thousand kilometers. The automatic transmission consumes much more fuel and is more expensive to maintain, but it has an increased smoothness and speed in switching.
Step 3
Please note: recently, automakers have begun to widely use CVTs, since they make the cost of cars much lower. And also, thanks to the infinite number of gears, the variator becomes unattainable with a conventional automatic transmission. Also, the difference lies in the fact that the automatic transmission has expensive maintenance and increased fuel consumption.
