A truck driver was on his way to deliver goods when his clutch plate malfunctioned again. The truck had only been driven for less than 50,000 kilometers. At this point, he called another friend who also drove a truck to complain. During the conversation, the truck driver could clearly state where it was bought, what brand it was, the mileage, and the warranty period, but he had no idea what material it was made of. Later, when he took a photo, it turned out that it was a "universal and highly cost-effective" product as described by the manufacturer, but in reality, it was a low-quality, low-cost clutch plate. The surface looked brand new, but it was made of low-end materials and couldn't withstand the heavy-duty, frequent high-torque operations of a heavy truck. It's like asking a big, strong junior high school student to carry heavy objects. Even though he looks capable on the outside, he can't actually handle it. It's all for nothing if you force him to do it. His back would break.Most people when choosing clutch plates, focus on the brand and price, but they ignore the most fundamental thing - what material it is made of. Just like when we build a house, the foundation must be solid; otherwise, everything is in vain.
Why are two clutch plates that look similar priced differently?
Why do some last for a long time while others burn out quickly?
The answer often lies in the material.The core function of the clutch plate is to achieve the connection or interruption of power between the engine and the transmission through the friction between it and the flywheel and pressure plate. The key point is the hard friction against the flywheel and pressure plate, so the material is extremely important.
Durability: This directly determines how long it can be used.
Friction coefficient stability: The material affects the matching of static and dynamic friction coefficients. If the two are close, the shifting will be smoother; otherwise, it is prone to jerking or slipping.
Heat resistance: The clutch has to withstand high temperatures during operation. Poor material quality will lead to heat attenuation. As the temperature rises, the material becomes softer, and when it is soft, it slips. The more it slips, the hotter it gets, and the hotter it gets, the softer it becomes. Eventually, it will have to be scrapped.
Impact resistance: It can't withstand heavy loads when starting. Materials that are brittle may crack immediately; materials that are soft may deform directly.
Returning to the story of that truck driver at the beginning. He couldn't drive for more than 50,000 kilometers before having to replace the clutch. Each time he replaced the clutch, the labor costs, parking fees, and maintenance expenses he incurred could have bought a new set of high-quality clutch plates. What really cost him was not choosing the wrong brand, not reaching an agreement on the price, but not even considering to select the material from the very beginning.This is just like what we said at the beginning: The material is the foundation of the clutch. If the foundation is unstable, no matter how shiny the top part is, it won't work.
