I found that many friends don’t know much about some car knowledge. For example, a friend recently asked: What are the gears and operations of a large truck? Let me give you a brief introduction below so that you can have a better understanding of these car knowledge. Okay, enough nonsense. Let's get down to business. Generally, the gear range of large trucks is 12th gear. Unlike family cars, big truck gear requires skipping gears.

Generally, large trucks have high and low speed controls, and the gear lever has an up and down shifting device. The first to sixth gears are low gears, and the seventh to twelfth gears are high gears. When you need to switch to a high gear, you need to shift the high and low speed control device upward, and then shift gears again.

Under normal circumstances, a truck does not need to start in first gear when it is fully loaded. Because the weight of the vehicle body is too heavy and the starting speed in first gear is too slow, trucks generally start in second or third gear.

Shifting requirements for large trucks:

Shifting requirements can be summarized in eight words: timely, correct, smooth and fast.

Timing: It means to grasp the timing when changing gears. Don’t change gears too early or too late.

Correct: The clutch pedal, accelerator pedal and shift lever should cooperate with each other.

Smooth: After shifting gears, release the clutch pedal smoothly to achieve smooth driving.

Fast; shift gears quickly, shorten the shifting time as much as possible, and reduce the loss of kinetic energy of the car.
