What's the problem The car is towed and the rear gear is turned on.What's the problem with the wrong sound when driving?

1. This kind of horizontal support must be seriously scratched, and even cause deformation at the bottom of the car.

2. Analysis of the problem: This problem usually occurs because the rigidity of the car body is insufficient, resulting in deformation of the vehicle while driving, friction or shaking between the door and the frame, or friction between steel plates due to dewelding in some places.

3. The reason why there is a sound in the car's hanging gear: the clutch is not stepped on to the end; the connecting mechanism is loose; the clutch disc is seriously worn and the pressure plate is damaged; the hanging gear is not in place.

4. There is no synchronizer in reverse gear, which is easy to cause this problem. Generally, it does not need to be repaired. I heard a strange sound when changing gears. Slight noise is normal, but loud noise is abnormal.The car is very noisy when changing gears, because the gears will rub when changing gears. There is no synchronizer in reverse gear, which is easy to cause this problem. Generally, it does not need to be repaired.

What will happen to the deformation of the front machine support beam of the car

1. It has an impact. The rigidity of the beam is more or less inferior to that before it was hit. After the deformation and repair of the beam, there will still be stress inside, which is easy to aggravate the fatigue of the beam. Of course, this is a case of serious deformation.

2. There must be an impact. The main problem is still the deformation of the beam. Even if it is repaired, it will definitely not be able to restore the original morphological parameters, so there will be some small problems such as abnormal sound of the vehicle and deviation in the direction. If the cylinder block of the engine is not damaged, it is not a big problem.

3. Whether the deformation of the beam is serious or not, it seriously affects the force point of the vehicle's balance. After the deformation of the beam, the height of the car body will be uneven, the vehicle will not run in a straight line, causing the tires to be under uneven pressure, and if it is serious, there will be a flat tire phenomenon. The deformation of the beam will also cause the driver to control the car unstable and prone to accidents.

4. After the deformation of the beam, the height of the car body will be uneven, and the vehicle will not run in a straight line, so that the tires will be under uneven pressure. If it is serious, there will be a flat tire phenomenon. The deformation of the beam will also cause the driver's unstable control of the car and prone to accidents;The beam deformation can only be corrected with a car beam corrector.

5. The collision deformation of the front beam of the car will affect the driving safety, resulting in the front beam and tilt deformation of the wheel, direction shift, and serious tire wear. The frame is generally composed of longitudinal beams and crossbeams. There are two main forms, side beam type and middle beam type, which are supported on the wheels through the suspension device, the front axle and the rear axle.

Songhuajiang likes the resonance of the car when idling, especially when the car is cold, but it will be better after oiling, and the acceleration...

Engine foot mat, and gearbox foot mat. Is there any bad one? The engine support beam is the one with the foot mat to see if it is deformed.Whether the fixing ring of the silencer is damaged or falling off. It came into contact with the car rack. The answer is over. Hand-ty-word.

Because pure electric vehicles use a motor when the vibration frequency of the engine is coupled with the natural frequency of the transmission system or some parts of the body, it will produce idle resonance, resulting in shaking. Idling shaking oil may not shake.

The most common reason for car shaking is that the throttle valve is too dirty or the fuel injector has too much carbon.

Too much carbon accumulation If the carbon accumulation in the engine cylinder is serious, it will cause spark plug blockage and valve blockage, which directly leads to the shaking of the car when idling. If the acceleration ability of the car is not as good as before and the shaking is very long-lasting, you can consider cleaning the inside of the engine cylinder.

There are several glues in the Qichen 50 engine

1. The ball cage rubber sleeve is damaged, causing the lubricating grease in the rubber sleeve to be thrown dry, which is also one of the common causes of abnormal noise in the chassis, and it is a big abnormal sound of "clicking".

2. The aging of the window glass sealing strip, and the aging of the strip is the most likely cause of the abnormal sound of the window glass. If it is a new car with abnormal sound, you don't need to replace the adhesive strip immediately. Just buy a lubricating oil online and apply it evenly on the adhesive strip, and then try to lift the glass several times to check whether the abnormal sound has weakened.

3. There is an abnormal sound in the engine. Symptoms: There is a high possibility of abnormal noise in the engine compartment. Most people also judge from the sound source that it is a strange sound in the engine compartment, usually a harsh metal sound or a strange sound like a wind whistle.Solution: The technical status of a certain mechanism of the engine has changed.

4. Then distinguish the sound caused by what, whether it is the sound of friction or the sound of collision. There are many reasons for abnormal noise, such as the placement of foreign objects in the car, the misplacement of the rear seat backrest, the loosening of the exhaust pipe and the engine guard plate screws, and the reason of the car itself. The welding points hidden between the sheet metal and the interior, and the opening of the interior will also cause abnormal noise.

5. At the same time, the problem of high temperature of the gearbox cannot be ignored. According to the data of the Automatic Transmission Repair Association, "More than 90% of all faulty automatic transmissions are caused by overheating.
