Abstract

The technical problem to be solved by the present invention is to provide a high-performance clutch facing for heavy trucks with novel structure, reasonable material formula, balanced performance index, cost and application effect. A high-performance clutch face plate for heavy goods vehicles, which is divided into a friction working layer and a structural layer, the friction working layer includes friction linings of at least three different materials; the three friction linings of different materials include rubber of the same thickness Base friction lining, replacement rubber FA friction lining and ceramic fiber friction lining; the beneficial effects of the present invention are as follows: the structure layer surface of the present invention is provided with rubber-based friction lining, ceramic fiber friction lining and replacement rubber FA The friction lining not only enables the clutch plate to play the characteristics of the three different materials during the clutch operation, but when the clutch plate is used in the clutch mechanism of a heavy-duty truck, it can effectively reduce the fading resistance in high temperature and maintain a stable friction force, especially suitable for Used in heavy goods vehicles.

Description

Technical field

[0001] The invention belongs to parts of truck clutches, and particularly relates to a clutch face plate used 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 materials, 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 requir...
