Clutch plates, professionally known as clutch discs, are not unfamiliar to every car owner or driver. If chosen or used improperly, it is normal to change clutch plates in a year or two. This mainly depends on the driving habits of each car user, driving conditions, working conditions of the transmission system, as well as the flat wear of the pressure plate and flywheel, and the overall quality of the clutch plate itself. Next, let's explain the composition of the clutch plate.
The most commonly used clutch plate friction plates on the market include Komac, Guanliang, composite yarn, half copper, asbestos-free, filament and so on, too many types. But they are all some friction materials, just with different materials and additives.
Composite yarn is similar to asbestos-free, with some wire-like things inside, which are easy to break when burned, just like charcoal. After many cars burn their plates, they won't separate because they're stuck in the pressure plate. But it also has the advantage that it is not easy to damage the flywheel and pressure plate, is cheap, and is usually used in cars that run less frequently on flat roads. Half copper is half synthetic copper metal friction plate, with good wear resistance, good heat dissipation, not easy to break, and not too expensive. However, due to the hardness of synthetic copper metal, it is particularly easy to damage the flywheel and pressure plate surfaces.
It's the steel plate sandwiched between the two friction plates. When the friction plates burn out, it is exposed. It not only plays a role in fixing the friction plates but also has the function of installing and stabilizing the shock-absorbing springs. Many large clutch manufacturers will spend a lot of money to purchase carburizing testing equipment just to test it, like quenching. If the temperature is too low, it is easy to deform, and if the temperature is too high, it is easy to break.
It plays a shock-absorbing role when the engine transmits power to the gearbox, to reduce the instantaneous impact force when the engine power is output to the transmission system. In the past, most of them had 10 springs, and now many of them have nine or eight springs, with three or four levels of shock absorption, all designed to protect car components and passenger comfort.
It is the "iron pagoda" in the middle with teeth, which ultimately transfers power to the gearbox through a shaft.
After saying so much, the bottom line is that the clutch plate is a consumable item that must wear out. If the plate is too hard, it will damage the flywheel and pressure plate, so good driving habits are a necessary factor in extending its service life. Avoid driving with half-clutch, a new friction plate can be burned within half an hour with half-clutch, and try not to shift gears without stepping on the clutch, as you may not be able to control the speed every time. The push-type pressure plate should regularly check the clearance between the clutch separation pump plunger, and if there is no clearance, find a repair shop or adjust it yourself until there is clearance.
