    Commonly used clutches for large trucks are single-disc, double-disc, multi-disc, booster plate, the truck is under pressure, and the clutch is a multi-disc clutch. The clutch plate of a truck is a consumable item, it must be worn, and the plate is hard to damage the flywheel pressure plate, so good driving habits are a necessary factor to prolong the service life. These friction materials mainly use asbestos-based friction materials. With the increasing requirements for environmental protection and safety, semi-metal friction materials, composite fiber friction materials, and ceramic fiber friction materials have gradually appeared.

    The friction plates of the clutch are powder metallurgy materials, asbestos-based materials, and paper-based materials. The surface allowable temperature, allowable pressure, friction coefficient, and service life of powder metallurgy materials are relatively high. The asbestos-based material is molded with asbestos plus binders and fillers and is consolidated on a steel or iron base plate, and the allowable working temperature is low. Paper-based materials are interwoven with asbestos, plant fibers or a mixture of the two, and then bonded with resins after adding fillers.

    The friction plate is the main component of the friction clutch. The physical properties and mechanical properties of the working surface material directly affect the working performance of the clutch. The main requirements for the material are: the friction coefficient is large and stable, the dynamic friction coefficient should be as close as possible to the static friction coefficient, and the strength High, can withstand impact, not easy to crack and peel at high speed.

    In order to eliminate the possible wear and tear of the clutch parts due to dust, protective maintenance should be carried out. In order to effectively clean the parts, it is necessary to disassemble all parts, including the removal of the brake shoes, which can be thoroughly cleaned with a vacuum cleaner or an air hose to remove the All dust deposits, in most cases, do not require the work of removing the hub. Check the thickness of the friction plate of the pneumatic clutch of the mill as planned, and replace it properly, be sure not to exceed the wear limit of the friction plate, because the rivets or screws will scratch the drum and may damage the spring.
