How to Become a Qualified Semi-trailer Driver?
Many friends think that semi-trailers are difficult to control. In fact, it is not. What we want to say here is: as long as you control yourself well, always remind yourself, work hard, you will definitely become a qualified old driver!
When driving a semi-trailer tractor, you need to pay attention to the following five points:
1. The semi-trailer is different from the one-piece vehicle, and the turning must be big! Pay attention to the position of the trailer wheels! Note that the cornering angle of the trailer is at least one meter greater than that of the main vehicle!
2. You must pay attention when overtaking a semi-trailer. Do not return to the driving lane immediately after overtaking the vehicle. The trailer is generally very long, so you must leave a distance! Tips: Observe the outside rearview mirror, after overtaking, the complete head of the rear car appears in the rearview mirror, and then return to the driving lane!
3. The semi-trailer will have a certain chance of side slipping on the snowy and rainy road, and the situation of the main vehicle on the top of the trailer will occur, so be sure not to brake suddenly, and accelerate quickly! Special reminder: Do not use the air-tight brake on icy and slippery roads! If the consequences of use are very dangerous, it will directly cause the driving wheels to stop rotating and the vehicle to turn off! Can't control the vehicle! Remember!
4. Regarding the brakes, the trailer brakes must be preceded by the main vehicle! The novice semi-trailer driving footwork is the most important. Many new semi-trailer drivers are used to stepping on the brakes with their toes.
Under normal circumstances, there is nothing wrong with this action; but in an emergency, it may not be possible to stop the car immediately. This is because the action of braking with the toes is not as fast as using the soles of the feet, which can depress the entire brake pedal to the bottom in an instant and exert the maximum braking ability.
The correct way to step on the brakes with your feet is to develop the habit of using the force between your toes and the soles of your feet to step on the brakes. At this time, if the vehicle speed is too fast and the semi-trailer does not have an ABS anti-lock braking system, it is very likely that after the brake is stepped on, the tires are bitten and the direction of travel cannot be controlled. The level of driving can be seen from the way a person usually operates the brakes. Stopping the car abruptly as soon as you hit the brakes, or failing to stop when it should be stopped, is not what a master driver should do.
Second, for beginners driving a trailer, the brakes of the car are often the most important. We should adjust the speed before turning. In case of emergencies, if you suddenly notice an obstacle, you should stop the tilting action immediately, straighten the body pressure bar, and then brake. When the speed of the vehicle is slightly slower, then lean the body to turn. Simply put, stop turning, brake, and turn again.
Third, the downhill braking of the semi-trailer is clever. The purpose is to prevent the front of the car from sinking too much, actively increase the weight of the tail wheel, and avoid pressing on the pressure rod. Use the accelerator skillfully, in addition to the foot brake, but also make good use of the accelerator to control the speed of the vehicle. In the case of a safe distance, once you need to slow down, you just need to release the accelerator and cooperate with the foot brake to control the speed more easily.
5. Regarding reversing, this requires hard work and hard work! Generally, it takes half a year for a semi-trailer driver to reverse the car skillfully! Key points: Reverse the car in the opposite direction, and turn the wheel in a foreseeable way! It should be noted that when the semi-trailer is reversing, do not repeatedly turn the direction, this is the worst habit, doing so will make you confused about the location of the trailer!
If you want to smash the oil when you increase the gear, then how much oil will we waste! The so-called boom oil is to be done when downshifting! The purpose of downshifting is to balance the speed of the engine with the speed of the vehicle, so as to achieve shifting without using the clutch!
How to increase the gear after the heavy vehicle starts on a slope: start in the first gear, refuel at a high speed, refuel and drag at a high speed, and then increase the gear normally! Some friends will ask why you need to drag the high speed. It is very simple. When you increase the gear on the slope, when you hit the neutral gear, the power speed of the car will drop sharply!
We have to wait for the high-speed engine speed to calm down before the smooth upshift, so for these two seconds! Get your car as fast as possible! In fact, these will be slowly realized in your future driving practice! Very simple! Just be brave and careful! Don't always be afraid of not doing well by yourself, or afraid of parking on the slope! Peace of mind, it will be easy to do!
