How to solve the six-speed setback of the cvl transmission
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!
How to solve the serious setback of cvl at low speed
If the CTV is severely affected at low speeds, you can try the following solutions: 1. ** Hot car **: If the transmission oil does not reach a certain temperature, its mobility will be slow, and the cold car will not be sufficiently moistened when starting. The friction between the chain and the cone wheel will be large, and the clutch will be easily hit, resulting in a setback. It could be solved by heating up the car first and letting the transmission oil reach the working temperature. 2. ** Check and change the transmission oil **: If the transmission oil is not changed for a long time, it may affect the normal operation of the CTV transmission. It is recommended to change the transmission oil at a 4S shop or a repair shop. 3. ** Check the engine for carbon deposits and spark plug **: The engine's carbon deposits will lead to a decrease in power, an increase in fuel consumption, unstable idling, and a slow start when the car is cold. The reduction in the ignition efficiency of the spark plug will cause a large difference in the combustion conditions of each cylinder, affecting the normal operation of the engine and causing vibration and pause. If the engine is not sufficiently warmed up, the oil flow will be poor, and the friction between the pistons will be poor. When the engine temperature is normal, you can go to a major repair shop for inspection and maintenance. 4. ** Repair or replacement of specific parts **: - If the design of some brands 'clutches is not good, resulting in shifting impact, and the quality is not good, resulting in serious wear and tear of the chain, a large number of iron filings attached to the oil pan and shaking, you can consider replacing the CTV transmission with a good quality one. - If the wear gap of the Audi OAW-transmission friction plate exceeds the standard range, there will be phenomena such as starting shake, pause, impact, etc. This situation needs to be repaired according to the specific wear reason. 5. ** Using special maintenance methods **: For example, Hong Kong Elfa 2.4, loosen the accelerator, step on the oil, and then accelerate the gear shift. If the oil change and maintenance cannot solve the problem, it can be solved by the smart moment fine adjustment gear shift. The novel " Watching the Moon on Fish Island " is equally exciting.

The front shell of the Cvl transmission was changed, and there was a setback.
If there is a setback after changing the front shell of the CVS transmission, there may be several reasons: 1. ** installation problem **: During the process of replacing the front shell, if the installation is improper, it may affect the normal operation of the internal components. For example, it may cause the connection of some components to be not tight, the position is not accurate, or the seal is poor, thus affecting the flow or pressure of the transmission oil, causing a setback. 2. ** Transmission oil related **: - ** Insufficient oil volume **: During the process of replacing the front shell, if enough transmission oil is not added correctly, it will cause insufficient oil pressure, causing the CTV's hydraulic system to be unable to control the movement of the steel belt normally, resulting in a sense of frustration. - ** Oil quality or model does not match **: The transmission oil that does not meet the requirements is used. The performance of the oil, such as the smoothness and heat dissipation, cannot meet the requirements of the CTV transmission, and may also cause a setback. 3. ** Internal parts damaged **: - ** Worn or damaged transmission belt **: During the process of replacing the front shell, the transmission belt (steel belt) may be accidentally damaged, or after installation, due to the compatibility between the internal structure of the new front shell and the original, the transmission belt will be worn faster or the force will be uneven, which will reduce the contact area between the conical wheel and the steel belt, affecting the transmission efficiency and causing a setback. - ** Wear of the driving wheel bearing **: The operation of installing the front shell may affect the driving wheel bearing. If the bearing is seriously worn, it will affect the transmission of power from the conical wheel to the steel belt, resulting in a delay. 4. ** Control unit malfunction **: Although the replacement of the front shell seems to have nothing to do with the control unit, there may be circuit connection problems or some undiscovered interference to the control unit during the replacement process, causing the control unit to be unable to receive driving signals and control the operation of the entire system, resulting in a setback. If this happens, it is recommended that a professional technician conduct a comprehensive inspection and repair to accurately find the cause of the setback and solve the problem.

Life of cvl transmission
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.

Is it normal for the cvl to start off with a setback
It might be normal for CVs to have a sense of stagnation at the start, or it might be caused by some problems. Under normal circumstances, when starting or driving at a low speed, the vehicle may have a sense of stagnation due to the engine braking effect. The CVS transmission was developed with the concept of infinitely variable transmission and smooth output of power, but it may also have a sense of stagnation when starting or driving at a low speed. The instantaneous deceleration effect caused by the crisscross of gears was also a normal situation. Judging from the abnormal situation, it may be caused by the following reasons: first, the transmission oil problem, such as the transmission oil has not been replaced for a long time; second, the grease is not sufficient. When the cold car starts to shift gears, the CTV transmission needs oil to be moistened. If the grease is not sufficient, the chain connection is not smooth, and the clutch may produce an impact when it is combined, resulting in a setback in the start. Third, design and quality problems. Poor design of the clutch or chain wear exceeding the normal value may cause the CVS transmission to shake. Although it will not cause serious stagnation, it may also affect the starting. Fourth, if the filter of the filter element is not replaced regularly, the dirty things may cause the amount of oil passing through to decrease, and the internal grease pressure will decrease. Slowly, there will be phenomena such as stagnation in starting and inability to refuel. The novel " Watching the Moon on Fish Island " is equally exciting. Everyone is welcome to click and read it!
The working principle of the cvl transmission
The CVS transmission was mainly composed of two variable diameter rollers (shaped like a pair of cones) and a steel belt or chain. One of the rollers was connected to the engine (power input) and the other was connected to the drive shaft (power output). During operation, the transmission ratio was changed by changing the diameter of the rollers (that is, the contact diameter between the cone and the steel belt or chain). For example, when driving at a low speed, the diameter of the input end of the wheel was smaller and the speed was higher, while the diameter of the output end of the wheel was larger and the speed was lower. As the speed of the car increased, the diameter of the two wheels changed, causing the speed of the output end of the wheel to increase. According to the different power transmitting devices, it could be divided into steel belt CVs and chain CVs. When the steel-belt CVS works, the driving cone wheel presses the side of the steel belt formed by the overlapping of the metal sheets and the metal rings to form static friction force, and the hardness between the push sheet materials is used to form thrust force, so that the steel belt drives the driven cone wheel to rotate to transmit power. When the driving wheel is clamped to the middle by the oil pressure device, the steel belt moves upward along the side wall, the circumference of the driving wheel increases, and the circumference of the driven wheel decreases, thus realizing the amplification of the engine's torque-force. The chain of the chain-type CVS was composed of a ring-shaped steel sheet and a pull piece. When it worked, the chain did not directly contact the cone wheel, but the middle rocking arm pin was pressed to achieve the transmission of the moment.

The cvl transmission slammed on the accelerator
There may be the following reasons for the CTV transmission to slam on the accelerator: 1. The internal friction plate of the transmission was faulty. In this case, he needed to go to the 4S shop for maintenance. 2. The problem with the transmission oil could be solved by changing the oil. 3. If the oil pump fails, if the damage is not serious, you can apply soap on the damaged part, separate the damaged pump membrane from the intact pump membrane, stagger the damaged part, and then re-install it; if the damage is serious, it needs to be replaced. 4. When stepping on the accelerator, the inertia of the internal operating components of the engine caused an impact. This was a normal phenomenon and did not need to be solved. However, stepping on the accelerator itself did not conform to the working characteristics of the CVS and should be avoided as much as possible. 5. The corresponding speed of the transmission was not fast enough, and the speed of the upshift could not keep up with the speed of stepping on the accelerator, so there would be a sense of frustration when shifting gears. The solution was to step on the accelerator slowly. 6. With the intervention of the energy recovery system, once the driver released the accelerator pedal or stepped on the brake pedal, the generator would immediately start to work, putting some burden on the engine, affecting the engine speed, causing the engine speed to be out of sync with the clutch plate speed. This would cause a feeling of stagnation and need to go to the repair shop for repair. 7. If the grease is insufficient, new engine oil can be added. 8. For the Japanese CTV, the oil circuit of the electromagnetic valve was not smooth, and the movement of the valve core cutting the magnetic induction line was hindered, resulting in the insensitivity of the oil pressure adjustment and the occurrence of a setback. This was because the friction between the steel belt and the wheel shaft produced fine metal wear debris. Although it was attracted by the magnet, it could still block the oil hole and the filter core of the electromagnetic valve, causing the oil hole of the valve body to be blocked. The movement of the valve core was not smooth, and the pressure applied to the steel belt was not precise enough, causing the steel belt to slip and cause a setback.

The difference between cvl infinitely variable transmission and automatic transmission
There were the following differences between a CVS continuously variable transmission and an automatic transmission (here, automatic transmission refers to other types of automatic transmissions other than CVs, such as AT, etc.): 1. ** Transmission structure ** - CVs mainly used steel belts or chains (for example, some models used steel transmission belts) for power transmission. The oil pressure controlled the tightening and loosening of the driving wheel and driven wheel, and changed the working diameter of the belt wheel cone and the transmission belt (one wheel diameter increased, the other wheel diameter decreased) to achieve speed change. - The other types of automatic gears (such as AT) used a gear set to change the speed. It was through different gears to achieve power transmission and shifting. 2. ** Power transmission characteristics ** - Due to the continuous variable transmission method such as the steel belt, the CVS could continuously obtain any transmission ratio within the transmission range. The power transmission was continuous and smooth, and there was basically no sense of frustration during driving. - Automatic transmission (such as AT) was a computer controlled hydraulic transmission. There was energy loss, and sometimes it was obvious when shifting gears. 3. ** In terms of economy ** - The fuel economy of CVs was relatively high, and it was more fuel-efficient than some automatic transmissions (such as ATs). 4. ** In terms of power ** - The power performance of CVs was obviously better than some automatic transmissions (such as AT). 5. ** In terms of cost ** - The CVS system had a simple structure and low cost. Automatic transmissions such as the AT were relatively expensive. 6. ** In terms of discharge ** - CVs could reduce the amount of exhaust gas and had certain advantages in terms of environmental protection.

How to distinguish between cvl and at transmission
Distinguishing between CVs and AT transmissions can be done from the following aspects: 1. ** Shifting experience **: - The CTV did not have a real gear, and it could change the distance at any time and place. It was very smooth when driving, and there would be no feeling of shifting gears. When the fuel was evenly supplied to start accelerating, the speedometer pointer would slowly increase or maintain a speed. - The AT had a real gear shift, and the gear shift action was a few points. When the fuel was evenly supplied, the speed increased, then decreased, and then increased again. There was an obvious upshift action. 2. ** Torsion Resistance **: - CVs couldn't withstand large torques, and once they were large, they would slip, so they were commonly used in small displacement models or large displacement self-suction models. - The AT could withstand a large amount of power and could be matched with a powerful engine, which was suitable for violent driving. 3. ** fuel economy **: - The fuel economy of CVs was better. Under the same displacement engine, the fuel consumption of models equipped with CVs was lower than that of models equipped with AT transmissions. - The fuel consumption of the AT transmission was relatively high. 4. ** Cost **: - The manufacturing cost of CVs was lower, and the price and maintenance of vehicles were slightly lower than that of AT transmissions. - The cost of AT transmissions was relatively high, and the maintenance price was also relatively high. Many high-gear AT transmissions were even more expensive to repair than engines. 5. ** Principle of structure **: - CVs used a drive belt and a driving and driven wheel with a variable working diameter to transmit power. Like a correction belt, there were steel belts and cone wheels rotating inside to achieve continuous changes in the transmission ratio. - The AT mainly used a hydraulic torque-changer in combination with a traditional mechanical gear box (such as a planetary gear set) to achieve the gear shift function.
