• The word " transmission " or " gearbox " is one of those terms that are familiar to many, but most people do not know about the differences between many types of transmission used today. In any vehicle with internal combustion engine, the transmission is one of the most important components. This article explains some of the most popular automotive gearshmies and the principle of their operation.

  Transmission is a device whose purpose is to change the speed of rotation of the engine according to the amount of power required. The gearboxes provide correct transmission of power from the engine.

  

  Try to imagine a movement without it. The driving wheels would rotate the same number of times with each crankshaft rotation. Such a car would be unmanaged because the drive wheels would always rotate; Stop the car would disable the engine, and start it mean that the car will suddenly break from the place just you turn the key. Its productivity would be low and fuel consumption is high.

  The availability of a gearbox guarantees that your car engine rotation is best used, its performance improves, and you can put it on a neutral transmission. Neutral transmission uses the clutch mechanism that separates the engine rotation from the rotation of the drive wheels. Transmission is simply an indispensable part of any vehicle with an ICE.

  

  Many types of transmission have been developed and implemented by car engineers throughout history. We can divide them into two large groups: automatic and mechanical transmission . Especially in the last few decades, automatic transmission has developed much more than mechanical. We will tell the main points what you need to know about automotive transmission and help distinguish their types.

  1. Mechanical gearboxes span>

  

  the benefits of a mechanical gearbox is physical unity with a car, a strong driver's involvement and a sense of control. For this reason, cars for enthusiasts and some sports cars are still often equipped with mechanical gearboxes.Some motorists still consider mechanical gearboxes the best option, even if they have less power and slower switching time. But as automatic transmission technologies are improved, manual gearboxes will become more and more rare.

  2. Automatic gearboxes span>

  

  manual mode

  " or a function that allows the driver to control the transmission, choosing the desired transmission.

  3. Infinable gearboxes (variators or CVT) span>

  do not have a predefined set of gears . Instead, they contain a continuous set of transmission numbers that are used throughout the rotation range.

  Advantages of variators is the optimal use of power and torque of the engine (since the transmitting number is always in the correct ratio), compact dimensions and less weight. However, CVT transmission is less likely to be used in cars because it is not designed for intensive operation and towing, and is not ideal for driving on the highway. In scooters, some cheap machines and Toyota Prius, the variator is a common phenomenon.

  4. Double clutch transmission

  

  DCT or double clutch transmission is one of the most interesting automatic transmission found in modern cars. This design has become popular in sports cars and high -performance vehicles due to its compact size and lightning switching. DCT is an automatic transmission, but it has two clutches, one to switch the odd and one to switch even gears. unlike conventional automatic transmission , DCT does not have a hydraulic carrier. It can switch the gear almost immediately, as the system can quickly use a particular clutch package associated with 1-3-5 or 2-4-6 speeds.

  

  Volkswagen successfully implemented DCT in Golf MK4 R32 in 2003, after which it was used on many other cars. DCT is lighter than an automatic transmission, so it is easier to install on front -wheel drive models with transversely arranged engines. It is also a favorite among fans of sports cars, as it has proven its durability in high -yielding modes and the unsurpassed speed of gear shifting. Corporal petals at the wheel can be found in most cars equipped with a DCT transmission.

  

  5. Secretal (sequential) gearbox span>

  

  A serial mechanical gearbox is rarely used in cars, but is the best choice for riders.Paragraph designed to ensure a sense of control and manual gearbox at automatic speed and accuracy. It is designed for extreme requirements of the racing route. The sequential mechanical gearbox has a clutch. However, the clutch is only used to start and choose the first gear. The driver then uses a switch or switch switches to switch the gear. Without using the clutch every time, the driver can focus on driving the car, switch quickly.

  

  Due to the high cost, this type of transmission is not used in consumer cars, despite its advantages. In addition, there are no gaps of the gear or function of "kick-dan". A serial mechanical gearbox can only be switched to the next transmission up or down, rather than passing two or three gears like a regular automatic gearbox.

  6. Robotic transmissions (semi -automatic) span>

  

  semi -automatic can use clutch to run the car , but the rest of the switches are automatically done. The driver does not need to do anything. Another option is a clutch design (such as Porsche SportMatic), which is started as any machine and then switched as a manual gearbox.Semi -automatic was problematic, it lacks the performance and sensitivity of automatic or mechanical transmission, although the basic concept is correct.

  Currently Automobile manufacturers are actively developing automatic transmissions and trying to introduce them into the next EURO-7 that do not involve the installation of "clean" engines in the car will soon come into force. Therefore, many auto experts conclude that cars with Euro 7 standards will become the last cars with internal combustion engines, which allow you to receive a true drive from switching gears and direct interaction in the management of the machine.
