How to choose clutch discs?

The clutch disc damping disc, also called the torsion damping driven disc, is buffered by the compression spring 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 them is the deviation of the clutch foot feeling when driving. If a smaller number of springs with a lower stiffness coefficient are used, the cushioning will be strengthened and the clutch engagement will slow down, which can improve the ride comfort. However, for the sake of reliability, it is not recommended to use the above-mentioned clutch discs with less springs and weak strength and better cushioning on trucks.

In addition, there are some clutch plates that do not have a spring damping driven disc, which has a lower cost and is more used in agricultural vehicles. The characteristic is that there is no buffer, the clutch is very fast, so it will also be used in modified cars. Generally not recommended.

In addition, the connecting parts of the friction plate of some clutch plate steel plates are particularly weak. Under long-term high-strength work, the entire shock-absorbing driven plate will fall off. This also requires special attention.

Let’s talk about friction face sheets. Generally, the ones introduced in the market are relatively simple, such as core-spun yarn, non-asbestos, copper substrates, etc. The mainstream is non-asbestos sheets, while non-asbestos sheets have different quality and price due to various materials. They are also different.

The main components of the friction surface of the clutch plate are:

1. Skeleton (yarn, cloth, other fiber materials or metal wire);

2. Friction performance modifier (filler);
