The reason for the abnormal sound of cvl transmission at low speed

The following are some speed-up techniques for CVs: 1. For a model with an L-gear CVR transmission, the gear could be placed in the L-gear to achieve speed increase. 2. When accelerating, when the speed rose to about 2000 - 2500 revolutions, the accelerator was gently pulled back. This way, the automatic transmission would give an upshift command, and then refuel, making the upshift smooth and gradually accelerating. 3. When overtaking needed to speed up quickly, it could enter the S gear to complete the speed increase. When overtaking, it could also release the accelerator first and then step on it. At this time, the transmission would automatically downshift to meet the power requirements. After overtaking, release the accelerator, and the gear would return to the appropriate gear. Just use the accelerator control. The novel " Watching the Moon on Fish Island " is equally exciting. Everyone is welcome to click and read it!

The reason why the CVS transmission started to rattle could be due to the following reasons: 1. The abnormal sound made by the vehicle when it started was generally a fault of the suspension system, which may be caused by the loosening or damage of the engine support. In this case, the engine support needed to be replaced. 2. It may be caused by the damage of the internal valve body, but due to the stubborn dirt and impurities inside, especially the accumulation of dirt and impurities inside the valve body, resulting in the inability to effectively adjust the oil pressure, resulting in collisions, collisions, and slipping. In this case, the internal valve body needs to be replaced. 3. The wear and tear of the internal bearings of the transmission can also cause the CVS transmission to make strange sounds. At this time, the internal bearings of the transmission need to be replaced. 4. When the inner circle comes into contact with the journal of the main pressure cylinder, it is easy to wear and loose. There are many pockmarks on the journal, resulting in abnormal sounds. In this case, it is recommended to go to a 4S shop or repair shop for maintenance.

The abnormal sound of the CVS transmission may be caused by the following reasons: 1. ** Mechanical parts related reasons ** - ** Loose bolts and loose parts **: Loose bolts on the transmission case, loose grooves on the gear shift lever and the gear shift lever fork, etc., will cause the connection of the parts to be unstable and produce abnormal sounds. - ** Bearing problem **: Bearing wear and damage are common reasons. For example, the small bearing at the rear end of the input shaft of some of Japan's CVS transmissions was worn out, the bearing on the pressure cylinder was worn out, or there was a problem with the bearing connecting the moving and static parts of the vehicle. - ** Gear Failure **: The metal on the tooth surface of the gear is peeling off, the teeth are broken, the assembly is misaligned, and the gear mesh gap is abnormal. It will produce abnormal sounds during work. - ** Internal valve body problem **: The internal valve body is blocked due to the accumulation of dirt and impurities, and the oil pressure cannot be effectively adjusted, resulting in collisions, collisions, slipping, etc., resulting in abnormal sounds. - ** Inner circle and main pressure cylinder problem **: The contact between the inner circle and the journal of the main pressure cylinder is easy to wear and loose. When there are pockmarks on the journal, there will be abnormal sounds. 2. ** Oil related reasons ** - ** Oil not changed in time **: If the transmission oil is not changed for a long time, it will affect the smoothness and working condition, resulting in abnormal sounds. - ** Oil quality problem **: The replacement of inferior automatic transmission oil could not meet the normal requirements of grease, heat dissipation, and work, resulting in abnormal noise. - ** Defoamer in the oil fails **: When the defoamer component in the transmission oil fails, the oil will be stirred violently to produce a large number of bubbles. The places that should have been moistened by the oil film will be filled with bubbles, causing the internal metal parts to produce "cavitations", such as bearings, cylinder blocks, gears, conical wheels, etc. Small gaps will be worn out. When the car speeds up or speeds up, there will be a "whistle" that will be loud and small. 3. ** Other factors ** - ** Strange sound when the vehicle starts **: The strange sound when the vehicle starts is generally a fault of the suspension system, which may be caused by the loosening or damage of the engine support. - ** Abnormal sound when the vehicle turns **: The abnormal sound when the vehicle turns may be due to the fault of the steering system and the suspension system. During the turning process, the suspension system is deformed due to the tilting of the vehicle. - ** Strange sound when the vehicle is driving (good road conditions)**: It may be caused by the fault of the brake system components, such as loosening, wear, out of round brake drum or uneven brake disc. - ** High working temperature **: The CVS transmission's working temperature is too high, which will increase the pressure on the internal components, causing unstable operation and noise. In addition, the stubborn dirt and impurities accumulated inside the CVS transmission, especially inside the valve body, if not cleaned up in time to form a blockage, it would cause mechanical friction to produce abnormal sounds. - ** Water in the transmission was not repaired in time **: It would also affect the normal operation of the transmission and produce abnormal sounds.

The CVS transmission failure may be caused by the following reasons and can be solved according to the corresponding methods: 1. ** Problem with the valve body (applicable to situations where the usage range is high)**: - Reason: The valve body assembly belongs to the hydraulic control module, which supplies the entire oil pressure output. When it is used for a long time, the valve body and the valve path plungers may be worn off. Too many impurities will affect the blockage of the valve body, affecting the smoothness of the oil pressure supply and output, causing the transmission to have a sudden impact. - [Solution: The valve body needs to be repaired or cleaned. It may involve removing the transmission's torque-changer, valve body, and other components for inspection.] 2. ** Pressure cylinder and chain problem **: - Reason: The pressure cylinder and chain of the CVS transmission may be strained to varying degrees. Generally, the initial failure may be due to the disturbance of the oil pressure or the wear and tear on the surface of the pressure cylinder, resulting in a sudden drop in pressure relief. - [Solution: In the early stages, it can be repaired.] 3. ** Transmission oil problem **: - Reason: After the vehicle has been used for too many kilometers, if the transmission oil is not changed regularly (automatic transmission oil generally has a recommended replacement period), the transmission oil will be too dirty, and its mobility and smoothness will decrease, causing internal wear and tear of the transmission, resulting in failure. - Solution: Change the transmission oil regularly. 4. ** Transmission program version low **: - [Reason: When the version of the transmission program is too low, it will cause the transmission to be stuck.] - The solution was to go to the after-sales department and use the computer to upgrade the transmission. 5. ** Transmission design problem (for example, the reliability and stability of the CVS transmission on some models are average)**: - [Reason: Some models have design problems with the CVS transmission, resulting in problems such as stagnation and inability to speed up.] - [Solution: There is no particularly effective solution for this situation.] 6. ** Transmission oil pump malfunction **: - [Reason: A fault in the transmission oil pump will cause insufficient pressure in the transmission oil pump, causing the transmission to fail.] - Solution: Use a fault detector to read the pressure data of the transmission oil pump to determine if there is any abnormality. If there is a problem, replace it. The novel "Watching the Moon on Fish Island" is equally exciting. Everyone is welcome to click and read it!

There were many reasons for the abnormal sound of CVS transmissions and the corresponding solutions: 1. ** Strange sound when the vehicle starts **: If the vehicle starts to make a strange sound, it is usually due to a suspension system failure. It may be caused by a loose or damaged engine support. At this time, the engine support needed to be replaced. 2. ** Strange sound when the car turns **: This situation may be due to the fault of the steering system and suspension system. This was because when the car turned, it tilted, causing the suspension system to distort and participate in the movement. It is recommended that the owner go to the 4S shop or repair shop for maintenance. It is difficult for the owner to solve it personally, otherwise new problems may occur and cause unnecessary losses. 3. ** Strange sound when driving in good road conditions **: It may be a fault in the brake system components, such as loose parts, wear and tear, the brake drum is out of round, or the brake disc is uneven. The faulty parts of the brake system or the brake discs need to be replaced. 4. ** Bearing problem causes abnormal sound **: If there is a problem with the bearing connecting the moving and static parts of the vehicle, the driver can tell with a little brake. If the sound of the brakes does not change when the vehicle is moving at a constant speed, it is a bearing problem and the bearing needs to be replaced. 5. ** Abnormal sound caused by internal valve body problem **: The internal valve body is damaged, or the dirt and impurities inside the valve body accumulate and form a blockage, resulting in the inability to effectively adjust the oil pressure, resulting in collisions, collisions, and slipping. At this time, the internal valve body needs to be replaced. 6. ** Abnormal sound caused by wear of the internal bearing of the transmission **: In this case, the internal bearing of the transmission needs to be replaced. 7. ** The problem between the inner circle and the journal of the main pressure cylinder caused abnormal sound **: The contact between the inner circle and the journal of the main pressure cylinder is easy to wear and loosen, and the journal has pockmarks, causing abnormal sound. It is recommended that the owner go to the 4S shop or repair shop for maintenance. It is difficult for the owner to solve it personally, otherwise new problems may occur and cause unnecessary losses. For the Nissan-made CTV transmission, if the abnormal noise is caused by serious wear and pressure relief of the valve body or internal oil pump failure, the valve body can be replaced separately in time for maintenance; if the chain and chain cylinder are worn out due to delayed maintenance, the transmission box needs to be disassembled, the worn steel belt needs to be replaced, and the worn chain cylinder needs to be repaired. When the chain cylinder is not seriously worn, it can still be used after being polished on the machine tool. When the old JF series oil pump pressure regulating valve is stuck by worn metal debris, it can be replaced with the oil pump valve of Sonax. In addition, if it was a problem of sudden acceleration and abnormal noise, it could be solved by finding a professional reamer and reaming positioning tool from the equipment manufacturer, installing the reaming positioning tool into the output shaft hole of the transmission, enlarging the worn bearing base, removing the positioning tool after the reaming, installing the customized steel sleeve, and installing the original input shaft in place.

The abnormal sound of the CZT transmission may be caused by the following reasons: 1. After the steel belt was subjected to a large amount of tension for a long time, it was easy to wear and slip, resulting in abnormal sounds. 2. The wear and tear of the electro-hydraulic servomechanism may cause abnormal sounds. 3. The loosening of the bolts on the transmission case will cause an abnormal sound. 4. Loose grooves between the gear shift lever and the gear shift lever fork in the transmission would cause strange sounds. 5. Bearing wear and damage may cause abnormal sounds. 6. If the transmission oil is not changed for a long time, it may cause strange sounds. 7. The metal on the gear tooth surface peeling off, the teeth breaking, or the misplacement of the assembly may cause abnormal sounds. 8. The improper gear mesh gap would cause an abnormal sound. 9. Changing the low-quality automatic transmission oil may cause abnormal sounds. 10. If the transmission was not repaired in time, it would cause an abnormal sound. 11. The strange sound made when the vehicle started could be caused by the loose or damaged engine support, which could also be reflected in the abnormal sound of the CZT transmission. 12. Assembly clearance and bearing clearance problems may cause abnormal sounds. For example, the bearing wear problem of the Toyota CLV transmission model may not be obvious at low speeds, but at a certain speed, there will be sounds and may cause abnormal sounds. 13. The stubborn dirt and impurities inside, especially the accumulation of dirt and impurities inside the valve body, caused the oil pressure to be unable to be effectively adjusted, resulting in collisions, collisions, slipping, etc., which may also be the cause of the abnormal sound. 14. The high temperature of the transmission could also cause strange sounds. 15. The internal metal parts were worn out. For example, the gears, bearings, and other metal parts inside the Wanli Yang CLV25 transmission might produce strange sounds due to wear and tear after long-term use. 16. The gap between the output shaft bridge bearing base and the bearing was too large, which might cause the vehicle to shake and make strange sounds when turning corners, and the low speed and rapid acceleration of the chassis would shake and make strange sounds.

The design life of the CVS transmission was about 250,000 - 300,000 kilometers. However, in actual driving, due to the different conditions of the owner (such as driving habits, vehicle maintenance, etc.), their lifespan would also be different. Under the condition of good vehicle conditions, less intense driving conditions, and timely maintenance, its actual driving life could reach 400,000 kilometers. However, due to manufacturing errors, not all CVs could meet the design standards. However, within a certain probability range, CVs could run more than 300,000 kilometers. However, in general, the structural characteristics of CVs were relatively fragile, and their reliability in the power transmission process was not as good as that of AT, DV, and MT transmissions.
