Why does the truck not swing the heavy car, and what is the reason for the rear wheel shaking of the

Slight body shaking is a common condition encountered by many car owners. If the owner finds that the body shakes slightly when starting the vehicle or stopping the vehicle without turning off the engine, it may mean that the vehicle has the following three conditions: 1. If the body is found to have a slight shake or deviation during driving, it is generally a fault caused by tires.

First of all, it may be that the tire balance is not good, and the owner needs to do a four-wheel alignment and dynamic balance as soon as possible. 2. The other condition is more serious, which may be caused by the deformation of the steel rim, which requires the owner to go to a professional repair shop for inspection. This condition usually occurs in vehicles that are more than a year old.

Generally, when the car is replaced with new tires and new steel rims, it is necessary to do a tire balance, otherwise the steering wheel will be prone to shake when the counterweight is uneven. Body shake will have an impact on driving comfort and handling judgment. 3. The third situation is caused by the unbalanced deformation of the transmission shaft, which generally occurs in more cars that have collided with the chassis.

My car is also J6 before the four after the six, January 8, 2011 mentioned the new car, to today 8200 kilometers, during the period has not been overloaded, the brake is also the steering wheel shake! The empty car is better, but the heavy car can't hold it at all. Today just finished repairing from the service station, but it still can't be solved, and the repairman at the service station can't tell the reason, in a word, it's not repaired!

Four-wheel alignment is useless, and dynamic balancing is useless. And the problem of this car is not only this, the 3-bridge single-wheel lifting lug rivet is often broken, the repairman of the service station said, every day there are riveting beams, and the wheels are crooked out when they are driven (heavy vehicles can break the bow plate). I am from Xuzhou, Jiangsu Province, and I hope to communicate often and protect our own rights and interests!

Summary. The installation between the steering wheel, the steering knuckle and the front axle of the car has a certain relative position, and this installation with a certain relative position is called steering wheel alignment, also known as front wheel alignment. The front wheel alignment includes four contents: kingpin camber (angle), kingpin camber (angle), front wheel camber (angle) and front wheel toe.

This is the relative position of the two steering front wheels and the rear axle for the two rear wheels, which is called rear wheel alignment. Rear wheel alignment includes wheel camber (angle) and rear-wheel toe-in by rear. In this way, the front wheel alignment and the rear wheel alignment are collectively called four-wheel alignment.

Hello, dear, the question you asked, here is the answer to the following for you: it will have a relatively slight impact.

The front wheels have a bit more impact.

The installation between the steering wheel, the steering knuckle and the front axle of the car has a certain relative position, and this installation with a certain relative position is called steering wheel alignment, also known as front wheel alignment. The front wheel alignment includes four contents: caster (angle) of kingpin, inverted (angle) of Qi oak kingpin, camber (angle) of the front Zhengxing wheel and shouting of the front wheel. This is the relative position of the two steering front wheels and the rear axle for the two rear wheels, which is called rear wheel alignment.

Rear wheel alignment includes wheel camber (angle) and rear-wheel toe-in by rear. In this way, the front wheel alignment and the rear wheel alignment are collectively called four-wheel alignment.

Summary. Hello, glad to answer for you! The wheels of large trucks are very obvious when they run, because the tires of the car are unbalanced, the front wheels are deformed, the front shock absorbers are damaged, and the steering rod ball joints are damaged.

The wheels of the big truck shake very obviously, is it because the vehicle rolls over?

Hello, glad to answer for you! The wheels of large trucks are very obvious when they run, because of the unbalanced tires of the car, the deformation of the front wheels, the damage of the BenQ of the front shock absorber, and the damage of the ball head of the steering rod.

Truck blindness, also known as cargo trucks, generally known as trucks, refers to cars that are mainly used to transport goods, and sometimes refers to cars that can tow other vehicles, and belongs to the category of commercial vehicles. Generally, it can be divided into two types: heavy and light according to the weight of the loss of the car. The vast majority of trucks are powered by diesel engines**, but some light goods vehicles run on petrol, liquefied petroleum gas or natural gas.

The right rear wheel of my truck fell into the ditch, the left front wheel was suspended, and when I came up, I felt that the right side was low and the left side was high, and the wheel was a little shaky when I ran.

In this case, there is a high probability that the wheels are deformed.

Generally, the cab of large trucks has increased the suspension system, with shock absorbing springs and damping elements, which are to reduce the impact of road bumps on the cab, but the suspension system itself has a certain deflection, so there will be a certain amount of bump and shake when braking. If the bumps and shaking are violent, it is not normal and needs to be repaired.

Cab airbag suspension.

Analysis of the causes of car shake:

1. Cold start jitter.

First of all, starting from the cold start, the main reason for the cold start body shaking is that the fuel combustion is insufficient, resulting in insufficient power of the car. The ignition energy is low, and when starting, especially when the temperature of the fuel and lubricating oil is low, more oil is required to meet the power. Over time, the pole gap of the spark plug gradually increases, resulting in a decrease in ignition energy and poor fuel atomization, which leads to the shaking of the body.

In addition, the ignition energy can also be reduced due to the aging of the ignition coil, the aging of the high-voltage wire of the spark plug, or the leakage of electricity.

2. Suspension system problems.

Body shake is also related to the aging of the suspension system. It is mainly responsible for filtering out the shake of the engine when it is running, and if there is a problem with the suspension, these vibrations will be transmitted directly to the steering wheel and cab, affecting the driving. When the engine is idling, it is easy to cause shaking when the electrical system in the car is turned on.

The engine will increase the load when the electrical appliances are turned on, causing the idle speed to drop, and to compensate for the jitter caused by the idle slip, the engine will automatically increase the speed by partially. So, when the electrical system, especially the air conditioner, is turned on, the engine will often shake. This jitter is likely to be caused by the aging of the shock absorber and needs to be replaced in time.

3. Tire problems.

For tires, the tire must be balanced once when the car is replaced with new tires and new steel rims, otherwise the steering wheel will be prone to shake when the counterweight is uneven. If you find that the tire weight is not equal, you need to add lead to the inside of the rim to average the weight of the tires on both sides. Whether it is a general steel ring or a lightweight aluminum ring, it may deform or crack when subjected to a certain external force.

Deformation of the rim can cause shaking when driving, uneven weight of the rim can also cause shaking when driving, and incorrect angle of the rim can also cause shaking when driving.

4. Throttle problems.

The most common cause of car shake may be a dirty throttle valve and excessive carbon build-up in the fuel injector. After the car travels for a period of kilometers, the throttle valve will be too dirty to cause the throttle to close loosely or the idle motor to stagnate, resulting in the engine idling speed is too high, and the carbon deposits generated by the engine in this process will also cause the vehicle to shake, especially when starting the vehicle, the engine will shake more than normal, and even sometimes there will be a phenomenon that can not be started at one time. Therefore, when the body shakes, the first thing to do is to check the throttle and fuel injectors.

If you find that the throttle valve is too dirty or the fuel injector has too much carbon deposit, you should clean it with fuel injector cleaner or throttle cleaner in time.

5. The oil pressure is unstable.

If you still find that the body shakes after these are finished, it is recommended that you go to the repair shop to check whether the fuel supply pressure and intake pressure sensor are normal, if the oil pump supply pressure is not normal, the intake pressure sensor is wrong and improper work will cause the body to shake.

Summary. As for the brake shiver, it is usually caused by uneven wear of the brake disc, such as the outer side is thicker than the inner side or the inner side is thicker than the outer side, the brake pads are vertically clamped when braking, and the brake disc is uneven and does not fully fit the brake pads, and the higher the speed, the more difficult it is to brake the car.

It is also possible that brake shakings occur over a period of time after using inferior brake pads or replacing them with new ones. Due to the high metal content in the inferior brake pads, the performance is harder and the metal brake disc is easy to resonate and amplify the vibration, and the foot shakes occurs, so the mileage after replacing the new brake pads should be driven cautiously to avoid emergency braking.

The front of the truck shakes and runs like riding a horse, and the shaking when braking is also terrible?

Hello, glad to answer for you! If the steering wheel shakes when stepping on the brakes, it will be the brake shoe closure and the search for the disc is consistent with the wear of the brake hub, and the brake adjustment is too smart, and the tire pressure is too high and the tire tire is repaired with more pads. If you are satisfied with me, thank you.

As for the brake shiver, it is usually caused by uneven wear of the brake disc, such as the outer side is thicker than the inner side or the inner side is thicker than the outer side, the brake signal pad is vertically clamped on the brake disc when braking, and the brake disc is uneven and does not fully fit the brake pad will tremble, the higher the speed of the vehicle, the more difficult it is to brake the car. Brake shaky feet may also occur over a period of time when inferior brake pads are used or new brake pads are used. Due to the inferior brake cavity pad has more metal content, so the performance is harder, and when rubbing with the metal brake disc, it is easy to resonate and amplify the vibration, and the foot shaking situation occurs, so a mileage after replacing the new brake pad should be driven cautiously to avoid emergency braking.

If you notice significant body shaking when starting or stopping the vehicle without turning off the engine, it may mean that the vehicle has one of the following three conditions:

1.The engine has a lot of carbon deposits.

The most common cause of car shake is a dirty throttle or excessive carbon build-up in the fuel injector. When the carbon deposition inside the engine is excessive, the gasoline sprayed by the cold start fuel injector will be absorbed by the carbon deposition in large quantities, resulting in the mixture of cold start being too thin, making it difficult to start, in this case, only when the gasoline absorbed by carbon deposition is saturated, it is easy to get on the car, and the gasoline adsorbed on the carbon deposition after the car will be sucked into the cylinder by the vacuum suction of the engine for combustion, and the mixture becomes thick, and the combustible mixture of the engine is dilute and thick, causing idle shaking after cold start. The lower the temperature, the greater the amount of oil required for the cold start, and the more carbon deposits will affect the smooth cold start.

Solution: Clean the oil circuit and check whether the idle motor has carbon deposits and should be cleaned.

2.Problems with the ignition system.

Check the working condition of the spark plug, high-voltage wire and ignition coil, the ignition system is not working well, and the spark plug tripping condition is not good, which will also lead to this kind of failure.

Solution: Check whether the spark plug has too much carbon deposit, and replace the spark plug.

3.The oil pressure is unstable.

If you have cleaned the engine carbon deposit, washed the throttle, changed the oil pad and spark plug, etc., and still found that the body shakes when idling, it is recommended that you go to the 4S shop to check whether the fuel supply pressure and intake pressure sensor are normal, if the oil pump supply pressure is abnormal or the intake pressure sensor value is wrong and the work is not good, the body shake will be triggered.

Solution: Check the oil pressure and replace the parts if necessary.

4. Aging of engine parts.

Car jitter is also related to the aging of the engine feet (also known as claw pads). The engine foot is actually the suspension system of the engine, and the engine foot is responsible for absorbing the subtle shake of the engine when it is running, and if there is a problem with the engine foot, these vibrations will be transmitted to the steering wheel and cab, causing shaking when idling.

Workaround: Replace the parts.
