What is the reason for the squeak in the gearbox when the new Bora shifts?

There are many reasons, if the sound of shifting gears at low speed may be loose, if you are telling to change gears when driving or waiting for the car, it may be that the clutch is not in place, and then the sound of gear friction is made!

If you change gears at low speeds, the sound may be loose, and if you tell you to change gears when driving or when you are waiting for the car, the clutch may not be in place, and the sound of gear friction is emitted.

Gearbox mainly refers to the gearbox of a car.

It is divided into two types: manual and automatic, and the manual gearbox is mainly composed of gears and shafts, and the variable speed and torque are generated through different gear combinations; The automatic transmission AT is composed of a hydraulic torque converter, planetary gears and a hydraulic control system, which achieves variable torque through hydraulic transmission and gear combination.

How do you shift gears when the engine is not turned on, is it for fun?

I can tell you that this is not good for the gearbox gears, there will be gears on top of the situation, so there is a ring.

The belt is loose and the clutch disc is worn.

It's not that the clutch doesn't step on it, it's that it should be the sound of the gear clattering when it doesn't get in place.

Almost all cars are available, but they are a little smaller. , unless you change the engine guard, which is a big one, the whole engine can be protected from low.

The first batch of Bora I bought in 02, the quality really doesn't say anything, it's great. , the speed is fast, the speed is also fast, more than six years, there is nothing wrong with it.

Regarding your inquiry, this happens to many cars in winter. It may be due to the stiffening of each wide-cracked rubber part on the suspension of the vehicle when the weather is cool, and the lack of corresponding lubrication, which causes friction with other parts when the part moves, resulting in abnormal noise.

It is recommended that you mainly check the sound of the balance bar rubber sleeve or shock absorber rubber block. It is best to go to the repair shop to check it, if the sound is not loud, it can not be repaired.

Whether it is caused by the new replacement of brake pads, the new brake pads need to be run-in. If you are a new car, you naturally need to run in. Or it may be exercised, there are fine sand particles between the piece and the plate, and the grinding produces abnormal noise, this situation does not need to be repaired, just run to make the sand particles fall out.

If none of the above is the case, you need to see if the brake system is faulty, whether the fixing screws of the brake disc are still there, whether they are stable and whether they are damaged.

Volkswagen car discounts are less specific discounts to the local 4S store is mainly online ** not credible Many of the online are secondary stores to deceive outsiders to release the low price can not actually buy If you buy Shanghai Volkswagen is recommended to go to Beijing, Shanghai, Guangzhou and other regular 4S stores to buy **relatively low If it is too far to buy it in the local provincial capital city **Generally not very high Now the Spring Festival car buying season The most affordable time to buy a car is Qisen closed in August for two months Auto shows often have larger discounts.

Hello 1If the damping oil leakage or liquid level of the vehicle avoidance shock absorber is too low, the shock absorber can not be fully lubricated, and the shock absorber will be pure when passing over bumpy road sections.

If the gap between the front horn fixing points of the car is too large, it will also cause a similar abnormal sound;

The last common reason is due to the aging of the steering sleeve and ball head, which can only be completely solved by replacing the steering sleeve and ball head with a new one.

Hello, the speed bump has a creaking sound, it is estimated that the bushing at both ends of the shock absorber has a relationship, the winter is colder in spring, the bushing is polyurethane or hard rubber and other materials, it will become hard when it is cold and there is a gap in thermal expansion and contraction, all friction will have a sound, the problem is not big. If the car is several years old, you can consider changing the shock absorber bushing when you maintain it. Or a little grease.

In addition, the speed bump is also called the speed reduction ridge, which is installed on the highway to slow down the traffic facilities of the passing vehicles, the shape is generally strip-shaped, there are also point-like, the material is mainly rubber, and there are also metal, generally yellow and black to attract visual attention, so that the road surface is slightly arched to achieve the purpose of vehicle deceleration, generally set up at highway crossings, industrial and mining enterprises, schools, residential entrances and other road sections that require vehicles to slow down and easily cause traffic accidents, is used to slow down motor vehicles, A new type of traffic-specific safety setting for the speed of non-motorized vehicles. Speed bumps greatly reduce the occurrence of accidents at major traffic crossings, and are a new type of special spring sheltering facilities for traffic safety. The car is not only safe in driving, but also plays a role in buffering and deceleration, improving the safety of traffic crossings.

What is the reason for the abnormal noise in the second gear of the Bora gearbox, which may be due to the damage to the gear of the internal second-gear synchronizer, which causes the second gear to be abnormal. The clutch may not be fully pressed to the bottom when shifting, resulting in incomplete disengagement and damage to the gears and other parts of the synchronizer. It is advisable to disassemble the gearbox and check the gear of the synchronizer.

If there is abnormal noise in the neutral gearbox, but the noise disappears after pressing the clutch, it is generally caused by the normal meshing gear wear, loosening or ring of the front and rear bearings of the first axle of the gearbox; If there is an abnormal sound when changing gears, it is most likely caused by the ring of the rear bearing of the second shaft; For seriously loose or damaged bearings, they should be sent to the repair shop for repair or replacement in time. If there is abnormal noise in the transmission when the vehicle is driving at low speed, it will still occur after the vehicle accelerates and shifts, which may be caused by poor gear meshing in the transmission. In general, if the noise is low and uniform, it can still be used.

If the abnormal noise is uneven and noisy, it should be removed for inspection, maintenance or replacement. However, if there is a dull noise that is out of sync when the vehicle is driving and the noise disappears when holding the gear lever, it may be caused by the wear of the fork groove of the gear or the wear of the working surface under the gear lever, and the transmission should be removed for repair or replacement. If the gearbox makes rhythmic noise when the engine is idling, it is more obvious when the throttle is increased, and the vibration of the gearbox is felt at the same time, which is generally caused by tooth surface spalling or broken teeth.

This noise can also be generated if the repair and assembly are misaligned, and the center of the gear is offset. In this case, it should be immediately dismantled for inspection and, if necessary, replaced with new parts. Millions of car stools are subsidized.

It may be that the gear of the internal second gear synchronizer is damaged and the second gear is not normal. It is possible that the clutch is not completely pressed to the bottom when changing gears, resulting in incomplete separation and damage to the gears and other parts of the synchronizer. It is advisable to disassemble the gearbox and check the gears of the synchronizer.

If there is an abnormal sound in the neutral gearbox, but the abnormal sound disappears after pressing the clutch, it is generally the first shaft and front and rear bearings of the gearbox that are often meshed with worn, loose or loud gears; If there is an abnormal sound when changing other gears, it is mostly caused by the ring of the rear bearing of the two shafts; For seriously loose or damaged bearings, they should be sent to the repair shop for repair or replacement in time. If the transmission makes an abnormal noise when the vehicle is driving at low speeds, and it persists after the vehicle accelerates and shifts, it may be caused by poor gear engagement in the transmission. In general, if the noise is low and uniform, it can still be used.

If the abnormal noise is uneven and the noise is loud, it should be removed for inspection, repair or replacement. However, if there is an asynchronous sinking and collapsing noise when the vehicle is driving, and the noise disappears when holding the gear lever, it may be that the fork groove of the gear is worn or the working surface under the gear lever is worn, and the gearbox should be removed for repair and replacement or replacement. If the gearbox makes a rhythmic noise when the engine is idling, and the throttle is increased more clearly, and the vibration of the gearbox is felt at the same time, it is generally caused by the tooth surface peeling or broken teeth.

This noise can also be emitted if the maintenance assembly is misaligned and the center of the gear is offset. In this case, it should be removed immediately for inspection and, if necessary, replaced with new parts.

Today, here is to explain to you the knowledge of "why the Volkswagen new Bora gearbox is abnormal". The reasons for the abnormal noise of the Volkswagen new Bora gearbox: first, it is caused by the failure of the friction plate inside the gearbox; Second, it is caused by abnormal oil pressure in the gearbox; Third, it is caused by the failure of the gearbox valve plate.

If the gearbox produces abnormal noise, it is recommended that the owner go to the repair shop for a comprehensive inspection to determine the specific cause of the abnormal noise for repair. There are two types of transmissions, one is a manual transmission and the other is an automatic transmission. The driving skills of the manual transmission are higher than those of the automatic transmission, but the fuel consumption of the manual transmission is lower than that of the automatic transmission.

The main function of transmission oil is to keep the transmission system clean, and at the same time to lubricate and prolong the life of the transmission. For transmission fluid changes, it is an adhesive that does not need to be changed regularly unless there is a leak in the transmission fluid. For many cars, transmission fluid is also maintenance-free.

Millions of car purchase subsidies.

The reasons for the noise in the gear are improper operation, clutch failure, sprocket wear, and chain looseness.

On the issue of abnormal noise of automobiles, it is difficult for ordinary car owners to distinguish which ones are abnormal noises and which ones are reasonable abnormal noises. Only nearly 20% of the vehicles that went to the repair shop to detect abnormal noises were really faulty. In the case of a turbocharged engine, there is a must be a difference between the sound and the sound of a naturally aspirated engine; Models with engine guards may also make noises due to friction; After some car owners come into contact with different cars, it is likely that they lack their own understanding of mechanical knowledge, so they can distinguish the abnormal noise of the car and avoid wasting time and energy.

Second, the identification method of car noise:

In practice, due to the limitations of working conditions, it is difficult to use special instruments to measure the sound of the car, and the sound of the car can only be described and compared with the judgment of the sound in daily life. For example, the "rattle" sound caused by the dry friction of the bearing, and the "click" sound similar to the small hammer hitting the cement floor caused by the excessive valve clearance.

1. Correctly distinguish between normal and abnormal sounds.

The vibration of each mechanism in the work of the car will make a variety of sounds, but the sound does not mean that the car is faulty, in order to avoid unnecessary disassembly, we must first distinguish between normal sound and abnormal sound. The normal vibration sound of each cluster system component (such as the noise on the engine surface), the impact sound of the gear when shifting, the air intake sound and exhaust sound of using gas as the working source, and the gear meshing noise are all normal sounds. Abnormal noise (abnormal noise) can be divided into slight noise, general noise and malignant noise according to the impact on the performance of the car.

Slight noise, such as the flashover sound of high-voltage electric leakage, the slight loose sound of rolling bearings, etc., the general volume is small, the degree of loss of the grinding belt of the machine is not large, and there is no significant change for a long time, and this kind of fault can still maintain the normal driving of the car without repair.

3. When diagnosing abnormal noise, attention should be paid to creating good auscultation conditions and trying to eliminate the interference of other noises, so as not to affect the accuracy of judgment.

It is best to consciously amplify or reduce the sound, that is, use a screw or other metal rod as a stestological instrument to contact the sound part to amplify the sound, or use a single cylinder fire off to reduce the sound, so as to meet the needs of this diagnosis. The auscultation site should be kept quiet to minimize interference from human factors.

Generally speaking, there are two possibilities: one is the problem of the transmission oil itself, which leads to poor fluidity in the working state due to excessive viscosity in the cool car state, which makes the working parts abnormal cavity car. One is the problem of the gearbox itself, there is pressure relief inside, and the valve body or hydraulic piston is not working well, resulting in the taper wheel position not being matched in place.

Both of these causes can cause squeak and squeak.

Summary. In this case, it should be the sound of the shock absorber element, because the resonance of the start is large, otherwise you should go to the store and ask the master to check the rubber sleeve and cage.

The new Bora automatic transmission is in gear, why is the new Bora automatic gear squeaking, why is it squeaking?

Hello, happy to answer your questions.

The new Bora automatic transmission is in gear, why does it squeak?

First of all, you should first determine which position of the sound, if it is determined that it is a problem with the gearbox, first of all, you must rent a slip to see the oil of the type banquet, and secondly, check the torque converter.

If you talk about the chassis, you need to check the shock absorber original, the foot rubber sleeve.

A new car bought in March.

I understand what you said, but if you want a new car, you can go to the shop and ask the master to check the aspects I just mentioned, and it is not a big problem.

Driving in gear, it seems to be a sound of lack of fuel.

There was no sound.

There was a creaking sound when we walked to the car. There will be no more.

In this case, it should be the sound of the shock absorber element, because the resonance of the start is large, otherwise you should go to the store and ask the master to check the rubber sleeve and cage.
