How to adjust the direction of the car is not right, and how to adjust the steering wheel of the car

I found that there is an interesting phenomenon in the car rim, that is, many old drivers have some misunderstandings when driving, which indirectly leads to the understanding of some novice drivers for vehicle failures has also deviated, the biggest misunderstanding is the four-wheel alignment and dynamic balance, many novice drivers generally think that as long as the vehicle chassis is uncomfortable, the first thing that comes to mind is to do four-wheel alignment, in fact, this is a very big misunderstanding, this topic we will focus on four-wheel alignment and dynamic balance, to talk about the functions and roles of the two in detail.

High-speed jitter dynamic balance, the vehicle deviates and eats tires to do four-wheel alignment.

First of all, we must emphasize to you that four-wheel alignment and dynamic balance is not omnipotent, we must clearly know the cause of our vehicle failure before doing four-wheel alignment and dynamic balancing, and we must do the right medicine, otherwise it will be in vain.

1. Dynamic balance, the main function of dynamic balance is to balance both sides of the tire, so that when the tire is driving at high speed, the tire will not cause the entire body to swing because of the violent swing, under normal circumstances, as long as the tire of our vehicle is disassembled, the dynamic balance must be done, because the tire is not a uniform circle in the production process, if the vehicle travels to 80km h, the vehicle shakes violently, then it can basically be concluded that the dynamic balance data is too large.

2, four-wheel alignment, four-wheel alignment is more professional, four-wheel alignment involves the adjustment of the entire vehicle chassis, generally speaking, long-term driving in poor road conditions of the vehicle, the chassis will inevitably loosen the situation, at this time the chassis data error in all aspects will become larger, and these changes in the data directly reflect the situation is the vehicle deviation and tires eat tires, as long as the vehicle appears in such a situation, it must be immediately done four-wheel alignment.

There is a big difference between a vehicle mistracking and a tire eating a tire!

1. Vehicle deviation, in fact, vehicle deviation is divided into two situations, one is the steering wheel is crooked, and the other is the vehicle is crooked, everyone must learn to distinguish.

A crooked steering wheel is when the steering wheel of a vehicle deviates slightly at an angle, but the vehicle can stay in a straight line at that angle.

Crooked vehicle refers to the situation in which the steering wheel position is kept in the center, and the vehicle involuntarily looks at the left and right sides.

Under normal circumstances, the deviation only needs to adjust the ball head of the external tie rod on the steering machine, and the effect is very good with the data on the four-wheel positioning computer.

At this time, the first thing we need to adjust is the camber angle of the vehicle, generally starting from the rear suspension of the vehicle chassis, adjusting the inclination angle of the rear suspension after adjusting the rear suspension, and then adjusting the inclination angle of the front wheel and the toe, if the data error is relatively large, you may also need to use eccentric screws to adjust.

To sum up, when drivers find that there is a problem with the vehicle chassis, they must communicate clearly with the auto repair shop, first determine whether there is a problem with the vehicle chassis, and then they can do four-wheel alignment calibration, otherwise it is useless and cannot solve the problem in the real sense.

1. This situation generally appears in the model of mechanical hydraulic power steering, which is a very common way of steering power in the past, referred to as HPS in English, with mature and reliable technology and low cost. This type of steering power assist converts a part of the engine's power output into hydraulic pump pressure, which exerts auxiliary force on the steering system to steer the tires. When the steering wheel is not turned, the pressure in the chambers on both sides of the piston is the same and it is in equilibrium.

When the steering wheel rotates, the mechanical control valve connected to the steering column will be opened or closed accordingly, one side of the oil will no longer pass through the hydraulic cylinder and directly flow back to the oil storage tank, the other side of the oil continues to be injected into the hydraulic cylinder, the pressure difference between the two sides of the piston will be pushed under the action of the hydraulic force, and then produce auxiliary force, at this time we will feel that the steering wheel is not so laborious.

2. The steering pump drives the belt to slip. The steering pump is driven by a belt, and if the friction between the belt and the pulley is too small, the belt will slip on the pulley, and there will be a squeaky sound at this time. It may be caused by loose belt adjustment, excessive wear of the grooves of the pulley, or the new belt does not fit well with the old pulley.

A simple way to tell is to pour a little water on the belt when there is a noise, if the noise goes away, it means that the belt is slipping. At this time, first adjust the tension of the belt, if there is still a sound after adjustment, you can use it for a period of time to make the belt and the pulley fully match and then see if it is still ringing, if it is still ringing, you have to replace the pulley.

What to do if the steering wheel of the car is abnormal.

1. The sound of rebounding the clip after the turn signal.

2. The sound of the dust jacket of the direction column.

Whether you are in place or driving as long as you hit the steering wheel, you will hear the sound coming from under the steering wheel, you should check the steering post dust jacket, once the steering post dust jacket lacks lubrication, it will produce a dry friction sound, you just need to apply some butter in the dust jacket This sound will disappear.

Beat the steering wheel of the car to the right, expose the rear of the left front wheel, and then use a wrench to loosen the fixing nut, then rotate the left pull rod clockwise, and after adjusting the left front wheel of the car, continue to adjust the right front wheel in the opposite direction.

The so-called car deviation refers to the car driving at a constant speed on a flat, straight, dry and clean cement or asphalt road. When the steering wheel is released, the car automatically drives to the left or right, resulting in a driving phenomenon where the center line of the front and rear axles is inconsistent with the center line of the driving trajectory. Due to the influence of factors such as automobile structural design and manufacturing accuracy, no car will never deviate.

Automobile steering wheel deviation adjustment method:

1. You can do a four-wheel alignment. When the vehicle is used for a long time, the user finds that the steering wheel is heavy, shivering, misaligned, not returning to the position, or the tires are worn unilaterally and wavy;

2. Abnormal wear and tear such as block wear, eccentric wear, as well as floating, bumping, swaying and other phenomena when driving, you should consider checking the wheel alignment value to see if there is too much deviation and repair it in time;

3. The left and right sides of the four-wheel alignment increase driving safety, reduce tire wear, keep the steering wheel straight when going straight, maintain the steering wheel automatically after straight driving, increase the sense of driving control, and reduce combustion consumption.

Adjust the steering wheel of the vehicle to the right, revealing the rear of the left front wheel. Loosen the fastening nut with a wrench, rotate the left tie rod clockwise, and screw the left tie rod to shorten. Then repeat the previous steps and knock the steering wheel to the left, revealing the back of the right front wheel.

Rotate the right lever counterclockwise, and the right lever is elongated.

If the left lever is rotated in one week, then the right lever must also be rotated out for one week, and the amount of adjustment on both sides must be the same. Adjustment of the steering tie rod, if the steering wheel is in front, if the steering wheel is to the left, the left wheel will extend the tie rod outward, and the right wheel will be shortened inward, if the steering wheel is to the right, it will be the opposite.

The situation of improper deviation of the steering wheel is generally related to tire pressure, tire wear, chassis component wear, and four-wheel alignment. You can measure the tire pressure first, and when the tire pressure on both sides is not consistent, the vehicle will drive to the side with low air pressure. If there is no problem with the tires, check the use of the chassis parts, and the change in the value of the wheel alignment will also lead to the problem of improper steering wheel after a period of use, and it is also possible that the tie rod is offset to one side and causes the steering wheel to be misaligned.

If there is no deviation in the straight road driving, but the steering wheel angle is not correct, this has nothing to do with the 4-wheel alignment, only need to adjust the length of the left and right levers of the steering machine to solve.

There are many reasons why the steering wheel of the car cannot automatically return to the right, including damage to the car steering machine, wrong toe value, damage to the pendulum, etc., which are analyzed below.

1. Damage to the steering gear of the car:

When the steering mechanism of the car is damaged, the car will have symptoms such as difficulty in steering or the direction cannot automatically return to normal. In this case, the gap of the steering machine should be readjusted, and lubricated with lubricating oil, if the car steering wheel still cannot be corrected, it should be checked by a professional in a repair shop or 4S shop.

2. The toe-in value is incorrect

If the car does not do four-wheel alignment after replacing the tires, the toe-in value of the car tires is wrong, the tires on both sides will not reach the parallel state, and the car will not automatically return to the right due to resistance when steering. In this case, the vehicle should be re-aligned and the toe value adjusted.

3. Damage to the pendulum

If the pendulum rubber of the car is damaged, it will aggravate the wear of the inner side of the vehicle's tires, and affect the automatic centering function of the square number belt disc. In this case, replace it with a new pendulum glue.

Things to note about car steering machines:

1. When the car is parked, the steering wheel should be corrected, otherwise it will cause resistance to the steering machine, which will affect the life of the steering machine for a long time.

2. After the car replaces the tires, do the four-wheel alignment in time and check the steering machine.

3. Lubricate the parts of the steering machine on time.

What's going on with the steering wheel not right.

1. The steering wheel is not correct after the vehicle is used for a period of time, which has a certain relationship with the tire pressure, tire wear, wear and tear of various parts of the chassis, and four-wheel alignment. If the two front tires are not worn out in the same pattern, it will also cause the vehicle to deviate.

2. If there is no problem with the tire, it is recommended to go to the 4S shop to check the use of various parts of the chassis, and the change in the value of the four-wheel alignment will also lead to the problem of Bilu steering wheel being wrong after a period of use, and it is also possible that the tie rod is offset to one side and the steering wheel is not correct.

The steering wheel of the car needs to be adjusted in time, otherwise the potential safety hazards are great when driving, and it is very easy to have some collisions.

The difference between a misaligned steering wheel and a mistracking:

Deviation does not necessarily mean that the steering wheel is not right, and the steering wheel is not necessarily wrong, and the two can also coexist, both deviation and steering wheel error. I have encountered someone who said that the steering wheel is not correct as deviation, because after he hit the steering wheel horizontally, the car will run to the side, and he thinks that it is misaligned, but in fact, it is just that the steering wheel is not right.

Therefore, if you want to know whether your car is off, then find a relatively straight and flat road with few vehicles to try, it must be a flat road, potholes are not allowed, because the wheels will change direction when they press over potholes and bulges, and some roads will also have errors in the middle high and low in order to drain water.
