Drivers often hesitate which car to choose: with an automatic or manual transmission. Most often, beginners ask this question when choosing their first car or car for rent. Also, this topic is relevant for those who use only one type of transmission and are considering the option of changing the type of transmission.
In most cases, the answer to the question "Which gearbox to choose?" lies in the plane of personal preference, but still, mechanics and automation have real differences, which form their relative advantages and disadvantages.
What is a gearbox and what is its role in the operation of a car?
A gearbox is a mechanism that transfers torque from the engine to a movable part and redistributes power to additional equipment and drives of other parts. Gearboxes are used in a large number of equipment, machine tools and mechanisms. They play the same role in vehicles with an internal combustion engine.
This element of the transmission expands the range of speed and torque, allows reverse movement, which is used for reverse movement of the car, as well as prolonged disconnection of the running engine from the transmission. It is the gearbox that is responsible for the ability to control the car and the interaction of the engine and wheels.
Features of an automatic transmission
For the first time, the technology of automating transmissions on a car was presented by the Buick auto concern in 1947. Although the automatic transmission was used before - in Sweden already in 1928 buses were equipped with automatic gearboxes.
Modern automatic transmissions are arranged differently, but the principle of operation has remained unchanged. The one-piece housing houses the torque converter, which consists of a pump, turbine and stator. The oil flow generated by the pump drives the turbine and the stator wheel. Thus, the transmission of torque from the engine takes place.
The automatic transmission is capable of itself determining the most suitable gear ratio and switching them, which makes it possible to automatically start off without the participation of the driver, and the absence of a clutch pedal greatly facilitates the control of the car.
Compared to a manual transmission, the complicated design makes automatic cars more expensive than identical models on the mechanics. At the same time, this is compensated by lightweight handling and minimal driver involvement in traffic.
A car with an automatic transmission has the following advantages:
- ease of use;
- no motor overload;
- no engine power is lost when shifting gears.
Among the disadvantages, it is worth mentioning the increased cost of maintenance and repair, the increased weight of the car, higher fuel consumption and a reduced estimated operating time before repair. Also, a car with an automatic transmission cannot be started from a pusher - when the battery is discharged, evacuation is needed.
Strengths and weaknesses of a manual transmission
The design and construction of a manual transmission is much simpler, therefore it is lighter and cheaper. Also, its maintenance will be cheaper, and repairs are usually required no earlier than after 500 thousand km, while for automation this value is usually about 150 thousand km.
Controlling due to the presence of the clutch pedal will require certain skills and abilities. An untrained beginner can handle poorly and disable the car a little earlier than average.
Mechanics have many advantages:
- low cost of maintenance and repair; increased service life; less fuel consumption than automation; Efficiency allows you to use all the engine power; towing on a rigid or flexible hitch; starting the engine even with a broken starter and a discharged battery.
Of the minuses - the difficulty of driving for beginners, engine overload due to improper operation and an increased load on the driver when driving in the city.
Conclusions
To summarize, we can say that the automatic transmission is beneficial for the urban environment and quiet driving on flat roads. Mechanics give an advantage on off-road and mountain roads. Therefore, if you want to rent a car for city trips, then choose an automatic machine. If you are interested in long trips in Ukraine, then it is better to rent a mechanic.
