The cvl transmission starts with a creaking sound
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 cvl transmission has a strange sound when shifting gears
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.

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 reason for the failure of the cvl transmission
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.

Cvl infinitely variable transmission simulation 10 gears
Simulating 10 gears meant that there were 10 virtual forward gears during the operation of the CVS (continuously variable transmission). Theoretically, the CVS infinitely variable transmission had countless transmission ratio. It used two sets of belts to change speed and drive, and simulated 10 gears through algorithm control. This design allowed the engine to more accurately match the transmission system, which had many advantages. On the one hand, it could increase power, and on the other hand, it could improve fuel economy, allowing the driver to enjoy smooth acceleration while reducing fuel consumption. Moreover, during the entire gear change process, whether it was starting or accelerating, there was basically no sense of frustration like traditional gear shifting, which significantly improved the driving experience and the overall comfort of the car.

The advantages and disadvantages of cvl infinitely variable transmission
The CVS infinitely variable transmission has the following advantages: - Smoothly shifting: Since there is no gear set in charge, the transmission ratio is changed through the diameter change of the driving cone wheel and the driven cone wheel. There is no power interruption in the whole process, so the transmission process is very smooth, without hesitation and discomfort. - Good fuel economy: There is no gear difference, so the engine can easily be in the best power output state, and the transmission is always in the best transmission efficiency, thus achieving excellent fuel economy. - Simple structure: This made the manufacturing and research and development costs relatively low, while it was easy to maintain and had a low failure rate. The disadvantages of CVs included: - Limited power performance: The strength of the connecting belt was limited, and the engine's torgue could not be too large. Therefore, cars equipped with CVs often had average power performance and soft acceleration. They were usually only installed on models that did not have high power requirements. They were generally not suitable for high-horsepower and high-torgue models. The common CVs had no more than 250 horsepower. - Not suitable for intense driving: Once you drive on the mountain road or race track for a long time, it is easy to trigger the safety protection due to excessive heating.

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.
