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 reason for the abnormal sound of cvl transmission at low speed
Cvette transmission throttle creaking
The reason why the CVS transmission made a creaking sound when it retracted the accelerator was probably due to the following reasons: 1. ** Bearing problem **: Bearing wear and damage may cause this abnormal sound. For example, the main pressure cylinder was supported by a bearing at the rear of the transmission. If the inner circle of the bearing was worn loose at the contact point with the main pressure cylinder journal, and the journal had pockmarks, it might produce abnormal sounds. 2. ** Wear of internal components **: If the middle shell bearing is a consumable part, it will wear out after long-term operation at the end, resulting in an abnormal sound; if the front end is near the input shaft, it may be caused by a problem with the input shaft or the flywheels; if the parts of the transmission that rub against each other (such as bearings, cylinder block, gears, conical wheels, etc.) are worn out, small uneven gaps may also produce an abnormal sound. 3. ** Transmission oil related **: - If the transmission oil is not changed for a long time, it may cause strange sounds. - If the defoamer component in the transmission oil failed, it would cause a large number of bubbles to be produced after the transmission oil was violently stirred. The places that should have been moistened by the oil film would be filled with bubbles, causing the metal parts to appear "cavitations", which would also cause abnormal sounds. 4. ** Other possible factors **: - The bolts on the outer shell of the transmission were loose, which might cause a strange sound when the accelerator was pulled back. - The grooves of the gear shift lever and the gear shift lever fork in the transmission were loose, which could also be one of the reasons for the strange sound.

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
Cvl transmission low speed
The CVS transmission may have some problems at low speeds. ** 1. Frustration and drag ** The CTV transmissions of brands such as Toyota, Honda, and Japan had a feeling of low speed and dragging. It was difficult to solve this problem by repairing the engine with current technology. ** 2. The reason for this phenomenon ** 1. ** Oil temperature factor ** - If the transmission oil did not reach the normal operating temperature, the car might start to move at low speeds. It was recommended to warm up the car first to raise the temperature of the transmission oil to the normal working range. 2. ** Oil quality factor ** - The transmission oil had not been changed for a long time, and the oil had aged and its performance had deteriorated, which could lead to this phenomenon. 3. ** Spark plug factor ** - Too much carbon on the spark plug would affect the stability of the vehicle at low speeds. 4. ** Engine factor ** - The engine ignition was weak or the air intake was low, which could also cause the CTV transmission to move at low speeds. 5. ** Injectors ** - The reduction of fuel in the fuel injection orifices had an impact on the vehicle's low-speed driving performance. Replacing the fuel injection orifices could improve the engine's combustion efficiency and ride comfort. ** 3. Points to note for special driving operations (for some CVs)** 1. ** For CVs that use a multi-plate clutch to connect the engine output ** - Long-term low-speed wriggling should be avoided as much as possible. This was because the clutch produced the most heat per unit of time during the combination process. Although the heat dissipation was good, there was a risk of overheating if it squirmed for a long time and repeatedly combined and separated. If the traffic jam is serious, you can properly pull away from the car in front to reduce the number of times the clutch is engaged. 2. ** General Driving Notice ** - There were steel belts connected to the conical wheels in the CVS structure to transmit power. This structure was relatively fragile. It was best not to drive too intensely. For example, it was best not to do operations such as launching and starting. Multiple launching and starting would cause serious wear and tear on the steel belt, which might cause the steel belt to slip, causing the transmission to be unable to transmit power. Also, don't always drive with the accelerator. If you use the S gear or drive at a high speed for a long time, it will cause the steel belt to rub and heat up. In the case of a light case, the over-heat protection will limit the power output, and in the case of a serious case, the steel belt will break. In addition, CVs generally had cold protection. When the engine was cold started, if the temperature of the transmission oil did not rise, the vehicle would not go when the accelerator was stepped on (the situation with the Japanese car might be more serious).

The cvl transmission is a little frustrated
The reason why the CTV transmission was a little sluggish was probably due to the following reasons: 1. ** Transmission internal fault ** - Failure of the friction plate: It may affect the smoothness of the power transmission and cause a sense of frustration. - Oil pump failure: If there is a problem with the oil pump and the oil pressure supply is abnormal, it will affect the transmission between the steel belt and the cone wheel, resulting in a pause. 2. ** Oil related issues ** - Transmission fluid problems: For example, the deterioration of the oil or insufficient oil will affect the normal operation of the transmission, resulting in a setback. 3. ** Normal phenomenon is related to driving operation ** - The inertia of the internal operating components of the engine: Under certain working conditions, the inertia of the internal operating components of the engine will cause a certain impact, which is a normal phenomenon. - Gear shift response and accelerator operation: If the response speed of the transmission could not keep up with the speed of stepping on the accelerator, there would be a sense of frustration at the moment of gear shift. Stepping on the accelerator slowly while driving could help improve this situation. - [Energy recovery system intervention: When the energy recovery system works, it will cause a burden on the engine, affecting the synchronization of the engine and the clutch plate, resulting in a setback.] - Low-speed gear shift: When driving at low speeds, for example, when the first and second gears are frequently switched (if there is a similar concept of gears), the clutch will constantly separate and combine. In a short period of time, the power transmission will not be smooth, which may cause a setback. Avoiding frequent shifts between similar gears at low speeds can help reduce setbacks. - Insufficient grease: If the grease is insufficient, it may also cause a setback. Adding new oil can improve this situation. The novel "Watching the Moon on Fish Island" is equally exciting. Everyone is welcome to click and read it!
