Abstract

The invention provides a high-performance clutch plate for a heavy truck. The high-performance clutch plate for the heavy truck achieves the technical purposes of being novel in structure, reasonable in material formula and balanced and excellent in performance index, cost and application effect. The high-performance clutch plate for the heavy truck is divided into a friction working layer and a structural layer. The friction working layer comprises at least three friction linings made of different materials. The three friction linings made of the different materials comprise the rubber-based friction linings, the substitute rubber FA friction linings and the ceramic fiber friction linings, all of which are of the same thickness. The high-performance clutch plate has the following beneficial effects that due to the fact that the rubber-based friction linings, the ceramic fiber friction linings and the substitute rubber FA friction linings are arranged on the surface of the structural layer in a mixed manner, in clutch operation of the clutch plate, the characteristics of the three different materials can be brought into play, when the clutch plate is applied to a clutch mechanism of the heavy truck, friction force resistant to attenuation and stable at high temperature is effectively reduced, and the high-performance clutch plate is particularly suitable for being applied to the heavy truck.

Description

Technical field

[0001] The invention belongs to parts of truck clutches, and particularly relates to a clutch face plate for frictional contact in clutches of heavy trucks. Background technique

[0002] In the heavy-duty truck transmission system, the clutch is a key component that connects the heavy-duty truck engine and gearbox. The clutch face is a product of composite friction material, and its main function is to realize power transmission through friction.

[0003] At present, the clutch facings seen in the existing literature or the market are all single-layered, that is, the entire product is composed of a single friction working layer. The friction working layer must have excellent friction and wear performance and meet bending performance. The performance requirements of various aspects such as, thermal performance, as well as good machinability and low cost. This poses a great challenge to the formula design of the clutch face. Since heavy trucks have higher requirements...
