How to cross the unilateral bridge for large trucks B2

The B2 truck is several times larger than the average car in terms of size, because it is necessary to confirm the position when crossing the unilateral bridge. When crossing the unilateral bridge, wait for the left side of the front rib to align with the left side of the bridge on the bridge, and see if the body is correct in the distance, and correct it to be corrected; When the rear wheel under the axle tail sinks, the head of the car is raised, play a circle to the right, and when you see the left side of the second bridge aligned with the driver in front of you, you can make two circles to the left, look at the distance to compare the body, and when the body is on time, hit a circle to the right and return to the right.

Left"Tendons"To the left bridge: Look ahead, point with the afterglow, left"Tendons"Align to the left, i.e. the left headlamp (i.e. the left front wheel) is aligned with the left side bridge. Take a slight direction to the left and stabilize (because the car body is high on the left and low on the right to prevent deviation to the right), look at the vertical extension line at the far end and drive straight and cross the bridge smoothly.

If you feel that it is not right, you can play less and return less, correct it a little, and correct it before going on the bridge.

Extended Materials. The unilateral bridge is one of the four subjects in the automobile driver's license test (also known as "6 out of 9" or "4 out of 9" in some places), which mainly assesses the ability of the motor vehicle driver to use the direction of the vehicle he is driving, the accuracy of judging the position of all wheels and the trajectory of the vehicle, and the technical level of mastering the non-parallel driving of the vehicle. The driver should correctly grasp the direction, roll a narrow bridge on each side of the road under the left and right wheels, and pass smoothly.

The width of the unilateral bridge is only 20 cm, with the left bridge in front and the right bridge in the back. One is to still borrow references. There is a vertically raised "rib" on the left and right sides of the hood surface.

When driving towards the left bridge, aim the left "rib" at the left bridge. The rear wheel is halfway down the slope and you have to make a lap to the right towards the right bridge. Similarly, when driving, the "right" rib should be on the right bridge, the right wheel is on the slope, quickly turn the direction back to the right, grasp the steering wheel, and drive at low speed.

When the left wheel is on the bridge, slow down appropriately;

When the left rear wheel just got off the bridge, the direction immediately made a circle to the right;

When the front end of the left cover line is against the left edge of the right axle, the direction immediately makes two circles to the left;

When the right front wheel is on the bridge, the direction immediately makes a circle to the right; Then make a slight correction in direction until the front of the car is aligned.

Exam Notes:

1. The push wheel to the left should be coherent and continuous but gentle, and the speed should not be too fast and too fierce (generally at low speed, the timing of the wheel to the right after getting off the left bridge, when the distance between the left ridge line of the front and the left side of the right bridge is just less than 10cm, and then hit 9 o'clock at a gentle speed to the left).

2. At L, it is not early to be late, and it is not too small. Because if L is small, it means that the time of the return wheel is late, and the speed of the back wheel can be increased (the right hand pushes a little more, to 8 o'clock) to adjust the remedy. And if L is big, that is, the timing of the wheel is early, and the right rear wheel is not easy to go up.

3. After getting on the right bridge, pay attention to the right time, and if you return to the right early, you will fall off the bridge from the right side; If you turn to the right too late, you will fall off the bridge from the left side.

Method 1 Generally, the bridge on the left has to go up first, the front wheel under the bridge to the right circle, the rear wheel under the bridge back to the forward, at this time the speed must be slow, otherwise it will rush out. When the left front corner enters the left wheel.

When the line is 20cm, half a circle to the left, when the left rib is close to the left wheel line, first turn back to the direction to 12 o'clock, and then aim at the car rib and the left wheel line in a line, the direction does not move the accelerator pedal to cross the bridge, and it passes. Due to the unilateral bridge.

It is only 20 centimeters wide, with the left bridge in front and the right bridge in the back. On the hood surface, there is a vertical protrusion on the left and right"Tendons"。When driving towards the left bridge, take the left"Tendon scum"Align with the left bridge.

When the rear wheel is halfway down the slope, you have to make a half-circle to the right and drive towards the right bridge. Again, while driving, to"Right"The ribs are on the right bridge, and the front right wheel goes up the slope, quickly turns the direction back to the right, and grasps the steering wheel.

Drive at low speeds. <>

When you go on the right unilateral bridge, hit the steering wheel straight, and then the little finger of the right hand is facing the position of the unilateral bridge in front of you, and you can pass by hitting the right direction and going up. Method 2 1: Borrow references.

There is a vertical protrusion on the left and right sides of the bonnet"Tendons"。When driving towards the left bridge, take the left"Tendons"Align with the left bridge. 2. After getting on the bridge, slow down as much as possible (if necessary, you can step on the brake pedal.)

3. When the left rear wheel just got off the bridge, the steering wheel immediately turned to the right and drove to the right like a ruined bridge. 4. When the engine compartment cover is on the right"Tendons"When aiming at the left edge of the right bridge, the direction immediately turns to the left.

Unilateral bridge skills tips: the front of the car Hongzhao Nai left rib aligned with the left side of the bridge on the bridge to see if the distance comparison of the body is positive, not to correct back to the right, the rear wheel under the axle tail sinking, the front of the car when the direction to the right half a circle, see the left side of the bridge to the driver when the driver is in front of a circle, to the left direction of a circle, to see the distance to compare the body when the direction to the right half a circle, back to the right.

The width of the unilateral bridge is only 20 cm, with the left bridge in front and the right bridge in the back. There is a vertically raised "rib" on the left and right sides of the hood surface. When driving towards the left bridge, aim the left "rib" at the left bridge.

The rear wheel is halfway down the slope and you have to make a lap to the right towards the right bridge. Similarly, when driving, it is necessary to cover the spring "right" rib on the right bridge, and the right wheel is on the slope before the right wheel, quickly turn the direction back to the right, grasp the steering wheel, and drive at low speed.

1. The method of crossing the first left unilateral bridge is relatively simple, as long as you pay attention to one point, that is, the front of the left car is facing the middle of the left unilateral bridge. Just keep this direction and pass smoothly at a semi-linked speed. Wait until the rear wheels also come off the left side of the bridge and stop immediately.

2. After stopping, turn the wheel to the right and continue driving. When the left front of the car is just facing the right side of the right side of the right side of the bridge, that is, the right edge of the right side of the bridge, stop and turn the wheel to the left twice.

3. Drive at a semi-linkage speed, when the rivet on the wiper on the left side of the front of the car (that is, there is a small protrusion on the left wiper) is facing a point in the left side of the unilateral bridge on the right (this point refers to the intersection point in the middle of the unilateral bridge from the inclined state to the parallel state with the ground), and make a circle to the right. At this point, keep this direction and slowly cross the bridge on the right.

Unilateral bridge is one of the subjects of the automobile driver's license test, which is to test the ability of the motor vehicle driver to use the direction of the vehicle he is driving, the accuracy of judging the position of all wheels and the driving trajectory, and the technical level of mastering the non-parallel driving of the vehicle. Under normal circumstances, when the front wheel starts to get off the bridge, hit 2-3 points to the right, and when the middle point of the front of the car crosses the outer edge of the right bridge, it begins to turn back to the direction, and after feeling the front wheel climbing on the bridge, then return to the direction of Zhengchayan.

If you usually don't feel good about practicing, and the exam is not absolutely sure, Bu is not absolutely so willing to play more direction to the right, and wait for the front midpoint to cross the outer edge of the right bridge, even if it exceeds 1-2cm, it doesn't matter, because then it can be adjusted by returning to the direction, even if you play more in the right direction, the wheel falls outside the right bridge, but through the back direction, you can pull the wheel up, avoiding the embarrassing result of the wheel not on the bridge.

In addition, if you hit less to the right, once the wheels fall on the inside of the right bridge, the difficulty of adjustment is more, so it is easy to cause the wheels not to go on the bridge, if there is no absolute grasp of the person, to the right more dot in the direction of the posture, and then a little more, at least two wheels can definitely be on the bridge Otherwise, if the wheels are not on the bridge, then the exam will definitely not pass.

1. First of all, crossing the unilateral bridge is under normal circumstances, when we are ready to get off the bridge in the front wheel, we all have to hit 2-3 points to the right. Then, when the midpoint of the front of the car crosses the outer edge of the right bridge, we start to turn back, so that after the front wheels climb the bridge, we will return to the right direction.

2. Even if it is more than 1-2cm, there is no auspicious wheel seepage, because it can be adjusted by returning to the direction, even if it hits more in the right direction, the wheel falls outside the right bridge, and it can come back by hitting the direction.

3. In the end, if you don't play much to the right, as long as our wheels fall on the inside of the right bridge, then the difficulty of adjustment is much higher.
