Introducing Various Types of Heavy Vehicles Gearboxes

The types of gearboxes in heavy vehicles are not much different in terms of performance from the types of gearboxes which used in light vehicles. However, the high weight of heavy vehicles causes structural differences between the gearboxes installed in heavy vehicles and the gearbox system in light vehicles. If heavy vehicles did not have a proper gearbox, then they would not be able to move heavy loads. In other words, heavy machines without proper gearbox system would lose their efficiency. The gearbox system which is installed in heavy vehicles receives the torque generated by the engine and prepares it for transmission to other parts of the vehicle. When the gears of heavy machines start working, a group of gears in the gearbox system affect the force generated by the engine and send it to the differential system.

The power transmitted to the differential system is affected by the ratio of the gears in the gearbox, and thus the gearbox affects the entire movement of a car. During the driving process, the driver can adjust the engine speed by pressing the accelerator pedal. The gearbox system is affected by the engine speed and causes the vehicle to move by transmitting power across the functional parts of the car. During the driving process, the driver can adjust the engine speed by pressing the accelerator pedal. The gearbox system is affected by the engine speed and causes the vehicle to move by transmitting power across the functional parts of the car. According to the role of the gearbox in the process of moving the car and preparing the car to accomplish the purpose for which it was built, it is necessary to know the gearbox system to get acquainted with your car.

In this article, we will examine the different types of heavy machine gearboxes and the exact mechanism of their systems.

What is the Use of Gearboxes in Heavy Vehicles?

As already pointed out, it is impossible to produce heavy vehicles without considering a suitable gearbox system for them. The fact that these vehicles are now able to move heavy loads is due to the fit of their gearbox system with their performance. Because of the high weight of the body of heavy vehicles and the fact that these machines often carry ponderous loads, the driver needs more gears to create the proper traction and speed for movement. As a result, gearboxes of heavy vehicles provide drivers with more gears.

More gears in a heavy vehicle gearbox give the driver more choices. Thus, the driver can use heavier or lighter gears than usual at the different time and place to provide the primary and secondary traction needed to move the car. The issue of the suitability of the gearbox system with the weight of heavy vehicles is not limited to providing traction for movement. If heavy vehicles did not have gearboxes commensurate with their performance, their speed was also significantly affected. The gearbox system receives the necessary power from the engine in proportion to the shape of its gears, and gives it to the differential system in the best possible way. Unlike light vehicles, where the gearbox system is sometimes forced to reduce the amount of power which applied to the differential, the gearbox used in heavy vehicles sometimes multiplies the power received from the engine before being transferred to the differential system.

All that we have mentioned so far, included increasing of the power applied to the differential, providing sufficient speed for movement, providing primary traction, creating and maintaining secondary traction for movement, and other such things, are all part of the use of the gearbox system in heavy vehicles. However, if we want to sum up all these things in one sentence, we can say that the task of all types of gearboxes in heavy vehicles is to facilitate the movement of these machines.

A gearbox system which is commensurate with the needs of heavy vehicles can reduce amount of wear and tear as well as fuel consumption.

How the Gearbox Works in Heavy Vehicles?

To understand the performance of different types of heavy vehicle gearboxes, you need to first get acquainted with the general performance of the gearbox system. In the gearbox system, the driver deals directly with the clutch and gear lever. When the car engine starts to spin and somehow starts to generate power, an intermediary system must distribute the power generated by the engine among other parts of the car. This system is that gearbox which uses the gear to transmit the power. The driver unlocks the gears by depressing the clutch. Each gear number represents a specific group of gears. Actually, by placing the gear, the driver determines which group of gears will perform the task of transmitting power from the engine to the differential. By placing the gear, a group of gears are matched together. When the driver take his foot off the clutch, the gears will lock again. The matched gears will lock in the same position and transfer power from the engine to the differential.

Due to the wider use of heavy vehicles, these vehicles have more diverse gearboxes. If all the gear numbers were stacked together, then the gearbox would be very cumbersome. As a result, in heavy vehicles, in addition to the gears, there are also half gears. Therefore, the gear change is done through the buttons on the gear lever. By adjusting the machine on different gears and half gears, the process of controlling the movement of heavy machines will be greatly facilitated.

Nowadays, the gearbox of some heavy vehicles has 20 gears. The number of gears of these machines is displayed as 16+2+2. Drivers of these car models can access the 4 extra gears for direct movement by using the 'Range Switch' button. The total number of these gears is eight. By doubling the number of gears and considering the half gears, these gearboxes provide the driver with 16 gears. Besides these 16 gears, there are also two rear gears with their half gears. That is why the number of gears in some types of heavy vehicle gearboxes is 20.

Types of Gearboxes in Heavy Vehicles

Different types of heavy vehicle gearboxes can be classified into four groups:

• Normal gearbox that has about 1+ 5 to 1+ 7 gears
• …. with at least eight gears, but their use is becoming obsolete
• H gearboxes are one of the types of heavy machine gearboxes in which tradition and modernity are combined. These gearboxes have a structure similar to …. ; But instead of cracking, they use a button system.
• Two- lever gearboxes are another type of heavy vehicle gearbox that is widely used in the structure of Mac vehicles.

What are the Common Problems of Heavy Machine Gearbox?

Poor quality of gearbox oil, depreciation of springs and ball bearings installed in the car and lack of coordination between gear and engine speed are some of the technical reasons that can lead to a malfunction of the gearbox of heavy vehicles. Some driving habits, such as pressing the clutch pedal for a long time and putting your hand on the gearbox while driving, can also damage the gearbox system.

How to Change the Gearbox in Heavy Vehicles?

Replacing gearboxes in heavy vehicles is a highly specialized process, and drivers generally fail to do so. It is the driver's job to identify the behaviour of his car, to determine when it is time to change gearbox and then refer to a specialist as soon as possible.

Conclusion

Modern heavy vehicles owe their efficiency to their advanced gearbox system. Different types of heavy vehicle gearboxes are one of the systems in the automotive industry that have had distinct growth and development. Undoubtedly, knowing these systems makes it easier for us to work with and maintain heavy vehicles.
