The problem of dumping piles of large trucks is urgent, please point me down!

There is no standard answer, it depends mainly on feelings and experience. In fact, you only need to choose one as a standard for the middle rod and three rods, I like to use the middle rod as the basis, after the direction is killed, let the rear of the car close to the middle bar to go in, and slowly return to the direction according to the speed of the car after the rear is put into storage, so as to ensure that the left side of the car keeps a certain distance from the middle rod, until the car collar is straight, and the direction is back to the right. The three rods can basically not be seen, as long as the distance between the car and the middle rod is maintained well (subject to the distance between the left and right poles when the car enters the warehouse), the three rods will definitely not touch.

When the tail of the car is about to arrive at the door of the warehouse, it begins to return to the direction, according to the speed of the car, the fast back to the fast, the slow to the slow back to the slower, which you have to see clearly, I am following the feeling.

After hitting the direction to the right, go back a little back to the right , wait for the rear of the car to enter about a meter and then hit the right direction, and immediately return to the direction and return to the right place.

You do what I say, just do it a few more times.

In fact, whether you can go back depends on the location of your car, but if you want to go back, you can only return slowly and slightly. When you go back, you have not yet arrived at the door of the library to return to the direction in advance, as for how much to go back depends on your position and the distance from the library and the speed of the car

It's better to have a voice to talk to you.

I just came out of the exam in the morning and it's so hanging. It's good that I'm over...

The latest pile reversal techniques for large trucks are as follows:

When the pile is reversed, turn right and look back at the pole, and when the pole is marked, start to the right direction and hit the end. At this time, lean your head forward towards the steering wheel, turn right and turn back, keep the No. 2 lever always appearing in the lower right corner of the triangle glass in the right window, and when you can't see it, turn back a little direction, and then continue to hit the direction to the right to the end. Look at the left rear mirror and brake when you can see the number 4 lever in the middle of the left mirror.

At this time, look at the left and right rearview mirrors, which side of the car is far from the general direction to which side, immediately adjust the direction after playing, reverse the car into the B warehouse, then stabilize the speed, turn right and look back to see that the No. 5 pole is about to disappear and stop.

Reversing skills for large trucks:

Foot on the clutch to the end, hang the reverse gear, release the handbrake, slowly lift the clutch, hold the positive direction with both hands, when the car begins to reverse (the car is moving), count the time seconds with the index finger, when it reaches 5 seconds, hit the right branch base direction, look at the right reverse mirror, see in the mirror when the tail and No. 2 (middle rod) are 50 cm apart, call the hail back to the left 2 and a half or 3 circles, let the car reverse into the library.

When you see the rearview mirror in the No. 2 rod and the No. 5 rod recombined into a straight line, the direction is corrected, (correction method: wide wide rule, when you see the rearview mirror of the No. 5 rod wide, to the width of the direction correction) at the same time to see the underground yellow line parallel to the car, when the left and right rearview mirrors see the rear of the car when the distance between the two rods is equal, keep the direction still, let the car go backwards, at this time twist the neck to look at the rear window of the car, when the tail section of the car and the No. 5 lever are 50 cm apart, step on the clutch, and at the same time press the brake.

When inverting the left library, the main target position is: the upper left corner of the right rear window, the first benchmark in front (the nearest visual one), and the third benchmark in the rear (the farthest visual one) are in a line. Keep the steering wheel backwards, and when you can see the third pole in front of you through the rear of the car, try to keep the rear of the car 20cm away from the benchmark, which means that visually speaking, the car is within the third pole.

According to the general principle, the car is placed in the middle of the garage at this time, but the steering wheel remains to the right. So at this time, you should quickly return to the direction of the positive tire (how much to hit, how much to go back) and walk in a straight line. The correction for too much distance is:

Hit the steering wheel a little to the left, this left is to ask the tires to return to the left a little bit, the purpose of which is to reduce the distance to the sideline in the process of reversing. When you reach the desired line, you have to hit the steering wheel to the right once or twice (depending on the actual situation), and then swing the tires back to the left to keep the car in a straight line and go backwards into the target garage (which is the same as walking in a straight line). How to correct the distance too small:

Feel how you can't see the benchmark all the time, then be patient, and keep going backwards to the right, when there is a distance of about 20cm between the car and the sideline, and then slow down to the left direction, adjust the direction according to the straight line method. Of course, if you can't fall into this position, it means that the direction in front of you is too late, that is, it is irretrievable.

Therefore, it is better to pour the pile a little earlier than too late.

When you pour the right library, look at the nearest pole and the farthest pole and the eye three points in a line, that is, the time to the left to kill the direction. After hitting the direction of death, poke your head out to look at the rear of the car, and the direction of reversing is to make the rear of the car gradually close to the center bar. The ideal state is that the car is placed in the middle of the warehouse when it is close to the middle pole, and the task of reversing the warehouse can be completed as long as it returns to the positive direction and walks in a straight line.

The situation that will occur early is that the rear of the car is close to the middle bar, and the car is still oblique. The method of correction in this case is as follows:

The rear of the car is close to the middle bar, you can be close enough to keep a distance of 10cm, the tires are straightened, so that the car has gone a diagonal line, and when the rear turn is almost past the middle bar, immediately hit the left steering wheel twice, continue to go backwards, pay attention to the distance between the rear and the center line, if the rear of the car is close to the center line, go back to the right twice down the steering wheel, go straight. In the case of the late stage, the rear end of the car is too far away from the middle bar. At this time, you should not rush back to the steering wheel, but continue to go backwards, so that the rear of the car is close to the center bar and then return to the steering wheel, and then adjust the direction according to the straight method.

If you want to approach the rear of the car on the right side of the middle rod to touch the sideline, it means that the action of hitting the direction of the three-point one-line is too slow.

Good luck with that!

The first point mentioned in the pile reversal skills of large trucks is the parking position: the left side of the car must be parallel to the 1st line, and leave the 1st line about 2 meters, not less than meters (if less than meters, when turning the steering wheel into the B warehouse, due to the appearance of the rear overhang outward, the front of the car is easy to cross the 1 line); It can not be greater than meters, (if it is greater than meters, the lateral distance between the right side of the car and the door of the B library is reduced, the turning radius is reduced, the distance when adjusting the direction is shortened, the difficulty of storage increases, and the rear of the car is easy to cross the edge of the B library).

Timing of turning the steering wheel: when starting to start and reverse backwards at point A, you can first turn the steering wheel half a circle to the right, keep the car body inclined to the garage direction of the rear reversing, and wait for the rear of the car to be about 1 meter away from the edge of the garage (the extension line extended to the 1st line), and start to hit the direction into the B garage (note: the direction can not be too early, that is, the car should turn rounder, so that when the rear of the car enters the B warehouse, the car is already close to the positive.

If it is too early, it will cause the slope of the car to enter the warehouse increases, the difficulty of warehousing increases, and the rear of the car is easy to cross the edge of the B library), at this time, look at the left rear corner of the tail (the left rear corner when the head faces the rear), at the moment of entering the B warehouse, it is necessary to keep a distance of 50 cm (about 10 cm left and right) from the middle rod, if it does not meet the requirements, adjust the direction in time.

Back to the steering wheel lud time: after the tail into the garage, the steering wheel is still close to the state of turning feet, wait until the car center line (the straight line between the eye and the midpoint of the rear of the car) of the extension line into the bottom of the B library about 50 cm, start to return to the direction, and so on the tail swing with the flutter pin to (eyes, the midpoint of the rear of the car, the middle point of the bottom of the garage) three points into a line, the direction must be back to the right, then you can reverse the car to the bottom of the B library according to the method of reversing in a straight line. The method of entering the library at point B at point B is the same as the method of entering the library at point A, the direction is opposite, and the position of the look is opposite.

1. The first time you reverse into the left corner of the tail plate to the middle pile, quickly return to the steering wheel twice, the left and right can not be slightly corrected, the big side of the steering wheel over there, but not the direction, in the garage direction can not be more than half a circle; The second time I reversed into the middle of the tail panel, the finger just reached the left pile of the rear pile, and quickly returned to the steering wheel.

2. The first entry of the library should be from slow to fast to hit the steering wheel, and when half of the car is to pass, it is also from slow to fast to play the steering wheel; The first retreat is very important, before starting the steering wheel to kill the cavity of the branch seepage, when reversing the driver's side of the rearview mirror to see the pile, you can quickly return to the direction, when the car is on time to play one more circle, the back to be fast or slow on their own, it is best to slow first and then fast, retreat a little, stop and parallel to the sideline; The second advance and the second retreat are corrected, and I hope that the students will grasp it themselves.

Points to note:1First of all, the amplitude of reversing is larger, that is, the arc of reversing is larger, otherwise even if the car goes in, it will be out of the corner, which means that the far corner of the car (right corner) will be out of the restriction line (the corner of the car on the right side of the driver);

2.When starting and reversing, the steering wheel first hit half a circle to a circle, slowly let the car compartment close to the edge of the library, when the left corner of the car is close to the benchmark and 50-80 cm, the steering wheel to the right to kill, the left corner of the car will go first, see the horn into the time, immediately back to the steering wheel. (There is also an identification method for returning to the steering wheel after entering the warehouse:.)

For the trainees, do not look at the rearview mirror to identify the reversing position, directly look at the glass in the middle of the cockpit and the compartment, pay attention to the application of "three points and one line", the driver's eye is the first point, the middle axis of the glass window is the second point, and the right corner of the bottom of the garage is the third point

The left corner and the right corner here refer to the left side of the car when the driver is facing away from the car, and the right side is called the right corner.

3.The steps of the warehouse bureau Zheng do not need to remember too much, mainly the driving position before the warehouse is appropriate, it will be much easier to enter the warehouse, friends, and then study more about the reversing line before entering the warehouse, this is clear, and the storage will be very easy.

I'm not a coach, but I also have a lot of friends around me who are new to Hu Lahail car, and that's how I teach them, and the face-to-face communication effect is obvious, and the learning is also very fast.

Straight pile turning operating tools: steering wheel, clutch, transmission and brakes.

Initial state of straight pile: Jeep is started, clutch and brake are not operated (initial position), transmission is in neutral.

Forward operation of straight pile: the clutch is pressed to the end, and the transmission is in first gear (to the left and then forward). Slowly lift the clutch until the jeep starts and runs forward; The steering wheel is turned to the right (clockwise), and the front of the car is deflected to the right; The steering wheel is turned to the left (counterclockwise), and the front of the car is deflected to the left; The steering wheel remains unchanged, and the front of the car runs according to the original trajectory (those who go straight still go straight, and those who turn still turn).

The clutch is pressed to the end, the brake is pressed, the neutral gear is hung after parking, the clutch is raised, and the brake is raised.

Reverse operation of straight pile: clutch pressed to the end, transmission in reverse gear (to the right and then forward). Slowly lift the clutch until the jeep starts, then run backwards.

The steering wheel hits to the right (turns clockwise), and the rear of the car is deflected to the right; The steering wheel is turned to the left (counterclockwise) and the rear of the car is deflected to the left. The steering wheel remains unchanged, and the rear of the car moves according to the original trajectory (those who go straight still go straight, and those who turn still turn). The clutch is pressed to the end, the brake is pressed, the neutral gear is hung after parking, the clutch is raised, and the brake is raised.

Sideways view of straight pile: Left hand is holding the steering wheel, right hand is on the back of the passenger seat, turn sideways and look back, and the line of sight is centered.

Silent destruction reference point of straight pile reversal: There are artificial reference points and reference points for body parts pasted on the car body, which is necessary for beginners. Due to the differences in posture or sitting posture of each student, the starting point of the reference point needs to be adjusted accordingly, and through training, everyone's reference point will be corrected.

Precautions for straight pile reversing: Gear is mounted after the clutch is stepped on the bottom to avoid damage to the gears in the gearbox. Press the clutch first and then the brakes and do not put the engine in the wrong gear to avoid the engine stalling. When playing the steering wheel in place, do not apply the brakes to avoid unnecessary wear and tear.
