The role of the clutch must be clear to everyone, the clutch plate as the main loss of parts, after excessive wear and tear will appear clutch slip, and even the occurrence of engine brake failure, so regular inspection and replacement is necessary. This article gives you a brief introduction to the purchase of clutch plates.
The common φ360, 380, 400, 420 and other data in the clutch model name refers to the diameter of the clutch plate (or the outer diameter of the clutch platen). The larger the diameter of the clutch, the greater the torque that can be endured, so that it will be used on the heavy truck. Large size clutch.
The clutch plate generally corresponds to the vehicle model, and can correspond to the OE number (car part number). In fact, the clutch plate has a certain versatility, even if the disk surface has a variety of different styles, but as long as the corresponding parameters can be used as a replacement:
1. The outer diameter of the clutch plate (usually refers to the outer diameter of the friction plate, the key is to be able to install and match with the original clutch pressure plate);
2. Spline size (number of teeth, size diameter).
Generally, the clutch plate is excessively worn excessively, partly due to workmanship problems: flatness is not good, and the mass distribution of the circular plate is not uniform. We can look at the entire clutch plate and the intermediate steel plate flat to check the flatness. The smaller the size of the clutch plate is, the thinner the steel plate is. It will be easier to see that the steel plate is not completely flat, and there is a gap between the friction plates. This is usually where you can see the work of the clutch plate.
Clutch discs, also known as torsional disc brakes, act as cushions when the clutch is engaged. The number, length, and stiffness coefficient of the springs used on different clutch plates are different, resulting in different cushioning strengths. The direct consequence of using the clutch is that there are deviations in the clutch feeling during driving. If a smaller number of springs with a lower stiffness coefficient are used, the cushioning will be strengthened and the clutch engagement will be slower, which can improve the ride smoothness. However, for the sake of reliability, it is not recommended to use such a spring-loaded clutch plate with less damping and weak strength.
In addition, there are some clutch plates that do not have a spring-damped driven plate, which is relatively low-cost and is more commonly used in agricultural vehicles. The characteristic is no cushioning, and clutch engagement is particularly fast, so it is also used in modified cars. It is generally not recommended.
In addition, the friction plate connecting part of some clutch plates is particularly weak, and under the long-term high-intensity work, the entire shock-absorbing driven plate will fall off. This also requires special attention.
Let me say that the friction face sheet, generally introduced in the market will be relatively simple, such as core yarn, non-asbestos, copper substrate, etc., the mainstream is no asbestos sheet, and no asbestos sheet due to a variety of materials deployment is not the same quality and price It also varies.
The main components of friction plate of clutch plate are:
1. Skeleton (yarn, cloth, other fiber material or wire);
2. Friction performance modifier (filler);
3. Binder (resin, rubber);
4. Dyes.
Among them, the skeleton is the most important one, and there are many kinds of materials, most of which are composite materials, asbestos cloth, glass fiber, acrylic fiber, aramid fiber, metal wire and so on. Take KM181 face piece of Zhejiang Kema as an example, the skeleton material composed of aramid fiber, glass fiber and copper wire is used. The face piece is mostly used on clutch plates of medium and heavy duty trucks.
Asbestos sheet: Both heat resistance and mechanical strength are high and the cost is low. Since asbestos was recognized as a carcinogen, many developed countries have banned the import of asbestos products, and domestic production has also been greatly reduced.
Copper substrate: easy to identify shape, generally made into a multi-piece style, not the general ring-shaped friction plate, is characterized by absolute wear and high temperature, but the price is higher, in addition to the clutch platen strength is also required, The pressure plate is easily worn out by using a clutch platen with low strength, so it is not recommended to use a full copper-based clutch plate without replacing the clutch platen.
â— Postscript:
Of course, you can choose large brands or domestic manufacturers of clutch plates, quality can be guaranteed. If you have other options, you can try to test and compare yourself. But after all, the clutch plate, as an important transmission component, also plays a braking role, but it is not recommended to save the province.
