The main requirement of modern life, which is characterized, first of all, by an accelerated pace, is to ensure human mobility. And, probably, the main way to solve the problem of movement in space, for most people, was a car. However, the process of acquiring a "steel horse" is accompanied by a large number of questions, one of which is the choice of the type of transmission.
Manufacturers of modern cars equip their products with several types of gear boxes that differ significantly from each other: mechanical, automatic, robots, etc. How to make your choice optimal? What is the difference between an automatic box and a robot? We will try to answer some of the questions regarding the checkpoint in this article. We will focus on gearboxes installed on later car models, and therefore less known to the domestic motorist - CVTs, robots and automatic machines.
What is the difference between a variator and a robot?
First of all, the variator is a continuously variable type transmission, the principle of which is based on the transmission of torque from moving conical disks that act as pulleys through a stacked steel belt or a steel chain consisting of a large number of links. When pushing the drive discs apart and shifting the driven ones, the amount of torque at the output increases. Otherwise, its value decreases. This design predetermines the main drawback of the variator - the lack of a neutral position and reverse gear. However, manufacturers solve this problem, however, each in his own way.
To answer the question: “What is the difference between a variator and a robot?”, which was placed in the subtitle of our article, we will consider the advantages and disadvantages of both gearbox options. So, the advantages of the variator:
Fuel economy comparable to that of a mechanical transmission.
The minimum acceleration time in conjunction with a dynamic set of speed and the absence of jerks.
Achieving high engine speeds exclusively at high speeds, which causes a minimal risk of engine failure.
Easy to learn even for a novice driver.
However, along with the advantages, the variator also has disadvantages:
The complexity of the design of related equipment, which implies its costly repair.
The complexity of repair and restoration work.
The gear oil used in the variator has specific properties, which makes it not only rare, but also expensive.
Now, in the same vein, consider a robotic gearbox, or a robot that is, in fact, a manual transmission, supplemented by a control unit that controls the clutch and gear shifting process.
Advantages:
Simple design and low transmission oil consumption.
Less repair cost.
Possibility of functioning in the mode of mechanical transmission.
Low fuel consumption.
The disadvantages of a robotic gearbox are as follows:
