The gearbox in the car, which is an integral part of the SUV

SUV gearbox necessary when driving off-road, because without this element, off-road driving would be impossible. Lack of a reduction gear in larger vehicles operating in difficult conditions can cause the clutch to burn out quickly. automotive gearbox it is only needed for off-road madness. On a straight road, it will not be needed, because on asphalt the car does not need to increase the torque sent to the wheels. What is worth knowing about the gearbox?

What is a gearbox in a car?

The exact name of this device is a distribution and reduction box. What's this? An automotive gearbox is simply an additional gear that sits just behind the gearbox and is controlled by another, separate system. The reducer with the reducer works like a normal element. The gearbox in the car, judging by the name, reduces the speed and regulates it. torque.

How does a reducer work?

This part is placed on the outside of the gearbox, so it makes more sense than adding another gear to the gearbox. Thanks to this, all gear ratios are multiplied by two, so instead of the basic five gears, we have as many as ten. gearbox in the car divided into two sets:

• fast, called high - used for driving on a gentle surface, preferably on an asphalt or gravel road.
• low, called low - used for off-road driving, on a road with obstacles.

How does it look in practice?

The first speed range is the state in which gears can overlap. If you are driving in second gear, you can reach a high speed of 60 km/h. When moving in fourth gear, you can achieve the same speed at a lower, lower rpm. The most important parameter automotive gearbox respect. It depends on him whether the car will have more power in the wheels. However, it must be remembered that the greater the force in the wheels of the vehicle, the slower it becomes. Therefore, it is necessary to pay special attention to the gear ratio of the gearbox.

Do you need a gearbox in a car?

drive gear off-road vehicles must be driven on surfaces where it is difficult to move. It distributes drive and power to all four wheels, which allows, for example, to drive out of muddy terrain, and also activates the locking of the center mechanism. Thanks to the reduction gearbox, you have twice the driving possibilities as with the conventional one.

What gives the presence of a gearbox in a car?

Transfer case gives additional drive, and in off-road vehicles is an indispensable element that facilitates movement over rough terrain.

What is the function of a reducer?

The gearbox offers two gears, i.e. low and high, which are used for two different tasks. Low mode is used for driving on light roads that do not require a lot of acceleration and power from the car. These are usually straight roads, such as a highway or regular asphalt. Second mode gearbox in the car designed for off-road driving. The operation of the transfer case allows you to perform difficult maneuvers, such as climbing a steep hill or driving off a muddy road.

Under what conditions should the reducer be used?

Gearbox with reducer this is the part responsible for the smooth movement of the car in difficult conditions. When to use it? There are two opinions about this. The first says that the gearbox can be used all the time while driving in the field, because there this part is great. The second opinion is that the gearbox should only be used to overcome difficult obstacles.

More off-road power

gearbox in the car it is best to use it when driving at a limited speed, such as 50 km/h. This makes it possible to use more gears. However, this part works independently of front-wheel drive. In order not to overload the system, it is best to use it only in 4x4 mode.

Does the reducer have limitations?

drive gear limits the ability to tow another vehicle uphill only if the vehicle has a rigid front axle. To activate the gearbox, the car must stop for a moment. Only some cars are equipped with synchronizers that allow you to shift into a lower gear when driving slowly. Until recently, gearboxes with a classic gear arrangement were produced, but now they are abandoning these designs and creating new ones with a planetary gear. In tests, both reducers work very similarly.

SUVs with the best gearbox

The gearbox in the car plays an important role, because without it, trouble-free off-road driving would be impossible. Here are three off-road legends who have the best transfer case:

• The Jeep Wrangler Unlimited GME 2.0 Turbo Sahara is the latest model on the market to use a classic truss frame design. There is a gearbox with a ratio of 2:71;
• The Suzuki Jimny II is a very small off-road vehicle that will do just fine in the field with an efficient downshift gearbox;
• Mercedes G class - this car has four-wheel drive, which, coupled with a reduction gear, is great for off-road driving.

A gearbox with a reduction gear affects the efficient operation of the entire vehicle, which has to deal with uneven ground in difficult conditions.. The car copes well with various obstacles due to the power transferred from the engine to the wheels. The gearbox on an SUV is an irreplaceable thing. Every off-road enthusiast should look for a good car equipped with this useful mechanism.
