Currently, regardless of brand or model, any vehicle driven by an internal combustion engine will have a clutch, which must have friction plates as they are the main component of the device. Although the clutch is a device that appears in the engine transmission, it can also operate independently and is an important component in power transmission. Some may say, "My scooter does not have a clutch, it just goes when you give it gas." It seems that some bent beam vehicles do not have a clutch and can run when gears are engaged. However, this is only a cognitive deviation, because since the clutch is an essential device in power transmission, it will inevitably appear between the engine and the gearbox to cut off or transmit power, achieving the purpose of smooth vehicle starting.
Therefore, both scooters and bent beam vehicles have clutches, but their working modes and gears are different. The clutches on these two types of vehicles belong to automatic separation and do not require manual operation. Therefore, the introduction of automatic clutch plate is also applicable to these two types of vehicles. Although the working principles of clutches may vary, each clutch cannot avoid friction plates because this component is necessary to realize the free separation and combination of clutches, making it very important for the entire clutch. However, clutch friction plates are easily burnt out.
In simple terms, clutch slip means a decrease in the ability to combine. The main and driven friction plates, which should be intimate, are not sticking together as they were before due to a decrease in surface friction, leading to lower transmission performance of the engine, increased fuel consumption, and even the transmission of the whole vehicle being affected.
The most direct manifestation of this failure in automatic clutch plate will be expressed as engine noise, slow vehicle speed, and a clear "empty response." In severe cases, even if the gear is engaged, the vehicle may remain powerless. This phenomenon is not necessarily caused by poor vehicle quality, but due to improper operation. Different brands of vehicles have minor differences in friction plate materials, which are mostly fiber composite materials that are relatively wear-resistant for wet clutches that are often immersed in engine oil. However, when we operate excessively and illegally, the first to be injured is the friction plate.
For example, using the clutch as a transmission, frequently gripping the clutch handle while sliding downhill, semi-linking under high-speed state during starting, or semi-linking for a long time during daily riding may cause excessive friction, high temperature, smooth surface wear, and a decrease in its combing force. Composite materials may even fall off and become obsolete. Therefore, whether it is starting or shifting gears, the clutch should be used thoroughly to avoid excessive burden and achieve reasonable use.
Once the friction plate is burnt out, in addition to the aforementioned slipping phenomenon, serious issues may occur such as blocking the oil filter of the lubrication system because the detached particles from the friction plate surface may get stuck there. If this part is unfortunately injured, then the consequences will be even more serious, and the entire engine may be scrapped. In summary, although the clutch plate is not as fragile as we imagine, it will certainly burn out if not used properly. Therefore, for the sake of our own vehicles and wallets, gentle and reasonable operations should be performed to achieve an ideal match between oil and clutch to avoid trouble.
