Follow the instructions on the hairspring fitting to install a new airbag hairspring, generally turning clockwise to the bottom and then counterclockwise to the end.
The airbag balance spring is a wiring harness that ensures that the airbag can detonate normally in an emergency. Because the main airbag has to follow the steering wheel.
Rotation, so there should be a margin for the connecting harness, and it is necessary to ensure that the steering wheel is turned to the limit position to one side without being broken. This is especially important when installing, and try to keep it in the middle.
-
It's just that there is such a problem on one side. The hairspring is turned to the bottom first, and then it is enough to return 2 and a half times.
The premise is that the tire is in the middle position.
-
Direction, under the premise that the tires are positive (when dismantling the first right), you can first turn to the end in one direction, and then turn back to see a total of a few laps, half of it is good, the general car is left and right three laps (almost three laps).
-
It is recommended that you park the car right, and then adjust the steering wheel to the correct position, and then draw a line between the steering wheel and the center rod that plays a fixed role in the middle, mark the steering wheel in the right position, and then hit the steering wheel to the left to the end, and then install the hairspring, turn the hairspring to the left counterclockwise to the end, and then return a circle or half a circle (as long as the steering wheel is installed after the hairspring is still rotated to the left is OK), the steering wheel is OK according to the right position just drawn, and there is no need to count how many circles, this method is simple.

Imagine a length of wire harness wrapped around the steering shaft of the steering wheel. When the steering wheel is turned, it can be loosened in the opposite direction, or it can be wound tighter when it is appropriate, but there are limits. When the steering wheel strikes left or right, it is essential to ensure that the wiring harness does not break.
The working principle of the airbag hairspring: when the car has a frontal collision accident, when the airbag control system detects that the impact force (deceleration) exceeds the set value, the airbag computer immediately connects the tube circuit in the inflatable element, ignites the ignition medium in the tube, the flame ignites the ignition powder and the gas generator to produce a large amount of gas, inflates the airbag within seconds, makes the airbag expand rapidly, breaks through the decorative cover on the steering wheel and blows to the driver and passengers, So that the head of the driver and passenger and the head of the passenger can be connected directly. The airbag evenly distributes the impact force across the head and chest, preventing the fragile body of the passenger from colliding directly with the body, greatly reducing the likelihood of injury.
Airbags can effectively protect passengers in the event of a frontal collision. Even if the seat belt is not fastened, the crash airbag can effectively reduce the number of injuries caused by disorder. According to statistics, when a car equipped with airbags has a head-on collision, the degree of passenger injury can be reduced by up to 64%, and even 80% of passengers are not wearing seat belts!
As for the collision of the side and rear seats, it still depends on the function of the seat belt.
Millions of car purchase subsidies.

Hold the steering wheel with your left hand at 45 degrees, release your right hand, and hit your left hand clockwise to 45 degrees to the bottom right corner, without any cross-hands.
It is necessary to master the relatively safe steering wheel holding gestures. That is, the left hand is held near 9 o'clock on the steering wheel, and the right hand is held near 3 o'clock, and both hands should be grasped on the steering wheel without tension. Keep your thumb on the steering wheel naturally.
When hitting the steering wheel, alternate your hands to play the direction. When the steering wheel turns in one turn, the left hand turns halfway and the right hand follows to continue the direction.
-
Suppose the steering wheel is in the shape of a (t) shape, the left turn is in the shape of ( ) and the left half circle is the same right turn is the right half circle, the left turn is in the shape of (t) is a left wheel one circle, the right turn is a (t) shape is a right wheel one circle, the left turn is one and a half times ( ) is the left wheel one and a half circles ( ) is the left wheel one and a half circles Got it.

Find a seat on the banner in the middle of the steering wheel and count it for one or a half turns.
-
Generally speaking, the hairspring can be turned 6-7 times.
The technical requirements for a hairspring are: to have a given elastic characteristic; Less elastic hysteresis; small temperature coefficient (thermoelastic coefficient); Good anti-magnetic properties and corrosion resistance; The pitch is equal; The center of gravity of the hairspring should be as consistent as possible with the geometric center (especially important for the clock's hairspring); When used as a conductive element, the balance spring material should have a small resistivity.
-
This is actually very easy to do, generally speaking, the hairspring can be turned 6-7 times... You can turn the hairspring in one direction, turn to the end ** when you don't move) and then turn in the opposite direction, and count while turning to know how many turns the hairspring can turn? You straighten the front wheels of the car (that is, go straight), turn the hairspring to the middle number of turns, install the hairspring, and then install the steering wheel and other parts...
Hope mine can help you.
-
Six circles, five and a half circles, the general airbag is a few turns in the middle of the return.
-
Two and a half turns to the left with two sides and two circles.
-
How many turns the steering wheel can make, how much the hairspring can be.
Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.
Because the steering wheel of the car is generally hydraulic, if you don't put it right when parking, the hydraulic pump will be easily damaged, and you can't turn back when driving in the direction.
The adjustment of the seat in the cab of the car affects the driving safety, and the adjustment method is as follows: >>>More
First, there are the following reasons:
1. The damage of the external steering machine or the adjustment bolt of the free clearance adjustment bolt of the steering machine is too tight, which will also lead to the steering not returning. After-sales commissioning. >>>More
The EPS light is on means that the electric power steering system is faulty, and the symptoms are: heavy steering, abnormal steering noise, steering wheel shaking, poor steering wheel return ability, etc., it is recommended to go to the auto repair shop for maintenance in time. At this time, the car should be stopped as soon as possible under the premise of ensuring safety, ** seek help from a 4S shop or a professional auto repair shop, and it is best to let the trailer tow away. >>>More
