The obvious setback in the CVS transmission may be caused by the following reasons: ###I. Elements related to steel belts 1. ** Steel belt slipping ** - The CTV transmission was driven by friction with a steel belt. When shifting gears, the ratio of the speed of the driving wheel and the driven wheel needed to be maintained at a normal speed. When this ratio was abnormal (such as the speed ratio being too large, it was considered slipping), the oil cylinder would clamp the steel belt. However, in the process of shifting gears, there was a lag in the calculation of the electromagnetic valve and the establishment of the oil pressure. It was impossible to enter the full transmission state immediately after the gear was fully driven, which would cause a short slip. The change in speed from slipping to not slipping would produce a sense of frustration. 2. ** Steel belt worn or damaged ** - After a long period of use, the steel belt may wear out, affecting its normal transmission function, resulting in a setback. ###2. Engine related factors 1. ** Power output problem ** - When the output power of the engine to the transmission was not enough, for example, after the engine had serious carbon pollution, the cylinder would have a slight misfire when the load was increased. This wasn't a problem with the transmission itself, but a cylinder of the engine that was doing bad work, causing the angular speed of the output end of the crank to be different in a unit of time, causing the car to stumble or crash. 2. ** Engine and transmission matching problem ** - The car engine and the transmission used a matching electronic control strategy, and the hardware and software of the two would be interconnected as a whole. Under some conditions, such as when the vehicle glided at a speed of less than 15km/h per hour, if the engine and the transmission were not matched properly, it might cause a setback. For example, some transmissions were not properly programmed. When the driver released the accelerator, he could not control the hydraulic moment or clutch to cut off the connection between the wheel and the engine. During this period, there would be a sense of frustration like stepping on the brakes. ###3. Other factors 1. ** Transmission oil not changed regularly ** - If the transmission oil was not changed regularly, it might affect the normal operation of the transmission, resulting in problems such as stagnation. 2. ** Vehicle specific operating mode ** - When driving at a low speed in a traffic jam, when the accelerator was released and then stepped on the accelerator, or when driving at a speed of about 30 - 45km/h, the CVS transmission may also occasionally feel a sense of frustration. This may be related to the control strategy of the engine and transmission, as well as the cooperation of various components under these specific working conditions.

There were the following reasons for the setback of the CVS transmission: 1. ** Steel belt related issues **: - The CTV transmission was driven by steel belt friction. In order to ensure that the steel belt did not slip when shifting gears, the input shaft and the output shaft had a speed ratio requirement. When the speed ratio was abnormal, the oil cylinder would clamp the steel belt. During the process of shifting gears, due to the calculation of the electromagnetic valve and the lag of the oil pressure, the speed of the steel belt would change from slipping to not slipping, resulting in a slight setback, which was the so-called rush. 2. ** Transmission oil **: - If the transmission oil was not changed regularly, the internal grease pressure would decrease after the amount of oil was reduced, and there would be phenomena such as starting failure and inability to refuel. 3. ** Engine related factors **: - When the engine had serious carbon pollution, the load on the first gear would increase, and the cylinder would have a slight fire phenomenon. This was not a problem with the transmission, but a cylinder of the engine had poor work, causing the angular speed of the output end of the crank to be different in a unit of time, causing the vehicle to stumble or rush. - The impact caused by the inertia of the internal operating components of the engine may also cause the CVS transmission to have a sense of stagnation, which is a normal phenomenon. 4. ** Other factors **: - The failure of the friction plate inside the transmission would cause a sense of frustration, so he needed to go to the 4S shop for maintenance. - Oil pump failure may also be one of the reasons. 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, you need to replace it. - The response 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. The moment the transmission changed gears, a sense of frustration would appear. This situation could be alleviated by stepping on the accelerator slowly. - The intervention of the energy recovery system would affect the engine speed, causing the engine speed to be out of sync with the clutch plate speed, resulting in a delay, which would require repair at the repair shop. - When driving at low speeds, if the gears were frequently switched between the first and second gears (such as low-speed crawling in a traffic jam), the clutch would constantly separate and combine, and the power transmission could not be completed smoothly in a short period of time, resulting in a low-speed setback. If there was a sense of hesitation when starting and at low speeds, it might be that the turbine was involved in the low speed and affected the engine speed. - If the oil was not sufficiently moistened, it would cause a setback, which could be solved by adding new oil.

The reasons why the CVS transmission felt frustrated were as follows: 1. * * Steel belt related issues **: - The CTV transmission was driven by friction with a steel belt. When shifting gears, the driving wheel and the driven wheel had to increase their speed. When simulating shifting gears, in order to prevent the steel belt from slipping, the input shaft and the output shaft needed to have a speed ratio. When the speed ratio was abnormal (if it was too large, it was considered slipping), the oil cylinder began to clamp the steel belt. In the process of shifting gears, due to the lag of calculating the electromagnetic valve and the oil pressure, it was impossible to immediately enter the full transmission after the gear transmission, which would cause a short slip. From slipping to not slipping, there would be a change in speed, resulting in a slight rush, which was a sense of frustration. 2. * * Engine related problems **: - [Insufficient engine output power: When the engine has serious carbon pollution, the load will increase when the gear is raised, and the cylinder will have a slight fire.] This loss of fire was not a problem with the transmission, but a cylinder of the engine that did not work well, causing the angular speed of the output end of the crank to be different in a unit of time. This would cause the car to stumble or crash. - Engine speed fluctuation: Although the CVS transmission did not involve traditional gear shifting, when the accelerator was stepped on to refuel or the accelerator was released to decelerate, the fluctuation of the engine's torgue would also cause the vehicle to have a stumbling problem during driving. 3. * * Other factors **: - Transmission response speed: The reason for the pause in the upshift was mostly because the corresponding speed of the transmission was not fast enough. The speed of the upshift could not keep up with the speed of stepping on the accelerator, so there would be a sense of pause when the transmission shifted. - Energy recovery system intervention (on vehicles with energy recovery system): Most of the downshifts are due to the intervention of the energy recovery system. Once the driver releases the accelerator pedal or steps on the brake pedal, the generator will immediately start working, causing some burden on the engine, affecting the engine speed, causing the engine speed and clutch plate speed to be out of sync, resulting in a sense of frustration. - Gap beyond the standard range: Like the Audi CLV transmission, if the internal component gap exceeds the standard range, if the entire gap exceeds the range, there will be problems such as starting shake, stumble, impact, etc. - Transmission oil not changed regularly: Audi CLV transmission damage is also related to the transmission oil not being changed regularly, which may also indirectly lead to frustration.

There may be the following reasons for the CVS transmission to feel a sense of frustration: 1. ** Engine related problems ** - When the engine had serious carbon pollution, the cylinder would have a slight misfire when the load increased.

Slowly, there would be a phenomenon of starting and inability to refuel. 4. ** In terms of the normal characteristics of the vehicle ** - Even if it was a CVS transmission, because it was impossible to completely achieve a completely linear infinitely variable transmission, there would definitely be a peak, so there might be a slight sense of frustration.

The strong feeling of CVS downshifting may be caused by the following reasons: 1. ** Insufficient oil pressure or poor oil quality **: CVs rely on the hydraulic system to control the connection and separation of gears. If the oil pressure is insufficient or the oil quality is poor, the efficiency of the hydraulic system will be reduced, affecting the performance of the CVS, resulting in a sudden downshift. 2. ** Worn belt **: The transmission belt is the main component of the CVS. When it is seriously worn, it may cause a sense of hesitation during the engagement process. 3. ** Control unit malfunction **: The control unit is responsible for receiving operation instructions and controlling the work of the hydraulic system. A malfunction will reduce the efficiency of the CVS, resulting in a sense of frustration when downshifting. 4. ** Driving habit problem **: The driver's frequent acceleration and deceleration may cause the CTV hydraulic system to fail to respond in time, resulting in a delay in downshifting. It was suggested to change the oil, check the transmission belt, repair the control unit, and improve driving habits to solve the problem of CVS's frustration when downshifting.

The reason why the CTV transmission felt like it was being filled with oil was probably due to the following reasons: ** 1. Reason related to normal mechanical characteristics ** 1. ** The lag in the process of steel belt transmission and clamping ** - The CTV transmission was driven by steel belt friction. When shifting gears, the driving wheel and the driven wheel had to increase speed. In order to simulate gears (such as simulating six, seven, eight, etc.), the input shaft and the output shaft needed to maintain a certain speed ratio in order to avoid slipping during the shifting process. When the speed ratio was abnormal (for example, if it was too high, it was considered to be slipping), the oil cylinder would clamp the steel belt. However, in this process, there was a sense of lag established by calculating the oil pressure of the electromagnetic valve. It could not achieve instant seamless shifting like the complete transmission of gears. Therefore, there would be a change in speed from slipping to not slipping, resulting in a slight rush, which was also a sense of frustration. This situation was caused by the normal mechanical characteristics of the CVS transmission, which could not completely achieve the complete linear of the infinitely variable transmission. 2. ** Engine and transmission coordination problem (under special conditions)** - When the engine had serious carbon pollution, the engine output power was not enough when the first gear was raised. When the load was increased, the cylinder would have a slight fire phenomenon. In this case, it wasn't the transmission itself that had a problem, but one of the engine's cylinders did not work well, causing the angular velocity of the output end of the crank to be different in a unit of time, causing the vehicle to stumble or crash. ** 2. Malfunction related reasons ** 1. ** Transmission oil and filter problem (Audi CLV as an example)** - For Audi's CTV transmissions (such as the 0AWCTV continuously variable transmission), if the transmission oil was not changed regularly, the internal filter and filter would be blocked by dirty things. For example, after the dirty things in the internal filter were accumulated, the amount of oil passing through would decrease, and the internal grease pressure would decrease. Slowly, there would be a phenomenon such as starting up and being unable to refuel. The external filter was also very important and needed to be replaced during regular oil changes. 2. ** Problems related to friction plates (Audi CLV as an example)** - In the Audi CTV transmission, if the friction plate was seriously worn, such as the gap exceeding the standard range, there would be problems such as starting vibration and stumbling. The wear of the friction plate may be due to long-term use, and the pressure of the relevant components could not be sealed after wear. Even if the friction plate was not completely worn or burned, it would still cause a malfunction due to the gap caused by wear. The novel "Watching the Moon on Fish Island" is equally exciting.

Theoretically, CVs were infinitely variable transmissions. Power transmission was achieved through two cone wheels and a steel belt. The continuous change of the cone wheels allowed the speed ratio to be infinitely adjusted within a certain range. Therefore, under normal circumstances, CVs would not produce a sense of hesitation when shifting gears like the AT and the DG. However, due to insufficient strength of the steel belt or problems with the hydraulic torque-changer, some Japanese CVs might not be able to react in time when suddenly refilling or suddenly decelerating. As a result, there would be serious downshifts, low-speed pauses, acceleration delays, and other phenomena. Some CVs had low temperature protection when it was cold, and they would not go when they were refueled. In addition, if the CVS program was not well defined, when the vehicle slid, it would not be able to cut off the connection between the engine and the wheels in time, which would also cause a similar feeling of stagnation. There were also some CVS models that had problems with the steel belts and chains as they were used for a longer period of time, increased driving range, and aggressive driving habits.

The reason why the CVS suddenly accelerated and felt like it was slowing down might be the following: 1. ** Steel belt transmission characteristic **: CVs use steel belt friction transmission. When suddenly accelerating, the speed ratio of the driving wheel and the driven wheel will change rapidly. In order to prevent the steel belt from slipping, the oil cylinder will clamp the steel belt. However, during this process, the oil pressure of the electromagnetic valve was built with a sense of lag. When the steel belt slipped to the state of not slipping, there would be a change in speed, resulting in a sense of stagnation. This situation might be more obvious during sudden acceleration. 2. ** Engine power output problem **: - If the engine had serious carbon pollution, the cylinder might have a slight misfire when the load was suddenly increased. This was due to the poor work done by one of the engine's cylinders, causing the angular velocity of the output end of the crank shaft to be unequal in a unit of time, causing the vehicle to falter. This sense of falter was not entirely a problem with the CVS itself. - The inertia of the internal operating parts of the engine during sudden acceleration would cause a certain impact, which could lead to a sense of frustration. 3. ** Transmission oil problem **: When there is a problem with the oil, it may affect the internal transmission efficiency and oil pressure control of the CVS. It may cause a sense of frustration during sudden acceleration. 4. ** Gearbox response speed **: If the response speed of the CVS is not fast enough, the speed of the upshift cannot keep up with the speed of stepping on the accelerator when suddenly accelerating, and there will be a sense of hesitation at the moment of shifting. 5. ** Energy recovery system intervention (if there is)**: In some vehicles, once the driver suddenly speeds up and then releases the accelerator pedal, the generator in the energy recovery system will immediately start working, putting a burden on the engine, affecting the engine speed, causing the engine speed and clutch plate speed to be out of sync, resulting in a sense of frustration.

There were many reasons for the slow acceleration of an automatic car. From the perspective of the cooperation between the engine and the transmission, when rapid acceleration was needed, the depth of the accelerator pedal affected the increase of the engine speed. The automatic transmission adjusted the gear according to the situation, which would cause the speed fluctuation. This kind of gear change and speed fluctuation may cause a sense of frustration, especially for models with few gears (such as a 4-speed automatic transmission). When driving steadily, lightly stepping on the accelerator to promote the transmission upshift can reduce the sense of frustration; if you want high acceleration performance to step on the accelerator deeply, there will be an obvious sense of frustration when shifting at a higher speed. In terms of vehicle parts: 1. Clutch pressure relief in the transmission may cause a sense of frustration. The clutch needs to be checked for damage and repaired. 2. The transmission oil circuit is not smooth, such as the oil circuit is worn out, the oil has not been changed for a long time, causing deterioration, the smoothness effect is reduced, the filter screen is too dirty and the filtering effect is not good, so the wear material enters the valve body, etc., which may cause a setback. The oil circuit should be checked. 3. The transmission oil has not been added to the standard amount. If there is too little or too much oil, there will be problems. If there is a transmission oil gauge, you can check whether the oil gauge scale is within the standard range when the vehicle starts. 4. The damage to the electromagnetic valve could also be the reason. The sludge in the transmission oil circulated internally and blocked the oil path in the valve body. Over time, it would cause a series of problems such as high temperature, impact, slipping, and so on, which would cause a sense of frustration. In addition, problems related to the throttle, such as excessive carbon deposits inside the throttle, resulting in small intake air flow and low idle speed, may also cause frustration. In this case, the throttle may need to be thoroughly cleaned (such as dismantling and cleaning when the vehicle has a large number of kilometers). If the vehicle stopped but there was no fault alarm, they could first go to the 4S shop to check if there was an upgrade software according to the vehicle number. Under normal circumstances, the car's gear shift would not feel too strong. If the gear shift felt too strong, it might be a problem with the transmission and needed further maintenance.

The reason why the CVS transmission felt like it was stuck when it was refueled could be due to the following reasons: 1. ** Internal friction plate malfunction **: Need to go to the 4S shop for maintenance. 2. ** Transmission oil problem **: It can be solved by changing the oil. 3. ** Oil pump failure **: If the damage is not serious, 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 it is serious, replace it. 4. ** The impact caused by the inertia of the internal operating parts of the engine **: This is a normal phenomenon and does not need to be solved. 5. ** Transmission response speed problem **: The speed of the transmission upshift could not keep up with the speed of stepping on the accelerator. There would be a sense of hesitation during the shift. The solution was to step on the accelerator slowly. 6. ** Energy recovery system intervention **: When the driver releases the accelerator pedal or steps on the brake pedal, the generator will work and cause a burden on the engine, causing the engine speed to be out of sync with the clutch plate speed, resulting in a sense of stagnation. In this case, you need to go to the repair shop for repair. 7. ** Shift gears frequently at low speeds **: The gears are frequently switched between the first and second gears at low speeds. The clutch is constantly separated and combined, and the power transmission cannot be completed smoothly in a short period of time. For example, the feeling of hesitation at the start and low speed may be due to the interference of the turbine at low speeds, affecting the engine speed. The solution was to avoid frequent switching between first and second gears when driving at low speeds. 8. [** Insufficient grease **: Can be improved by adding new engine oil.] In addition, the CVS transmission was driven by steel belt friction. If the speed ratio of the input shaft and the output shaft was abnormal during gear shifting, the oil cylinder would clamp the steel belt. During the gear shifting and clamping process, due to the lag of the electromagnetic valve oil pressure, the speed change from slipping to not slipping would cause a slight setback. There was also a situation where the output power of the engine was not enough, or the load of the engine was increased after the engine had serious carbon pollution, and the cylinder had a slight fire phenomenon, which would also cause a setback. However, this was not a problem with the transmission. The novel " Watching the Moon on Fish Island " is equally exciting. Everyone is welcome to click and read it!
