The types of heavy car gearboxes are not much different in terms of performance from the types of gearboxes used in light cars. However, the high weight of heavy cars causes structural differences between the gearbox installed in heavy cars and the gearbox system in light cars. They lost heavy loads. In other words, heavy vehicles would lose their efficiency without a proper gearbox system.
It was impossible to produce a heavy vehicle without considering a suitable transmission system for it. The fact that today these cars can cope with moving heavy loads is due to the suitability of their gearbox system with their performance.
Given the high weight of the body of heavy cars and considering the fact that these cars often carry heavy loads. They also carry weight with them, the driver needs more gears to create proper traction and speed for movement. For this reason, heavy car gearboxes provide drivers with more gears.
Types of gearboxes in heavy vehicles
Types of heavy machine gearboxes can be divided into five groups:
🔸🔹Normal gearbox that has about 1+5 to 1+7 gears .
Modernity is mixed in it. These gearboxes have a structure similar to the gearboxes; But, instead of clicking, they use a button system.🔸🔹Double lever gearboxes are another type of heavy machine gearboxes that are widely used in the structure of Mack cars.
