Embodiment 1

[0042] In terms of structure, such as figure 1 As shown, the clutch face plate of the present invention is composed of a friction working layer and a structural layer 1. The structural layer 1 is formed in a ring shape, and its thickness is equal to the friction working layer; the friction working layer is staggered by friction linings of three different materials. Become. The friction linings of three different materials include rubber-based friction linings 23 with the same thickness, replacement FA friction linings 22 and ceramic fiber friction linings 21.

[0043] Such as figure 1 As shown, the number of rubber-based friction linings 23 is six, the number of FA friction linings 22 is six, and the number of ceramic fiber friction linings 21 is three; the three ceramic fiber friction linings 21 are regularly distributed at 120 degrees apart In the ring-shaped structural layer 1, each ceramic fiber friction lining 21 is equipped with rubber-replacement FA friction lining 22 on...

Embodiment 2

[0072] The difference from the first embodiment is:

[0073] The present invention takes into account the limitation of the composition of the ceramic fiber friction lining 21. In the manufacturing process of the finished clutch face sheet, the ceramic fiber friction lining 21 and the structural layer 1 are the most difficult to bond well, so it can be used in the ceramic fiber friction lining. 21 is provided with recessed fixing through holes, and the corresponding structural layer 1 is provided with mounting holes corresponding to the fixing through holes. The fasteners fix the ceramic fiber friction lining 21 to the structural layer through the fixing through holes and the mounting holes. On 1, the fastener can be a hexagon socket bolt as shown in the figure.

Embodiment 3

[0075] The difference from the first embodiment is:

[0076] The rubber raw materials are composed of the following parts by weight: 12 parts of high nitrile nitrile rubber, 11 parts of carboxyl styrene butadiene latex, 3.5 parts of basic zinc carbonate, 0.5 parts of accelerator DM, 10100.4 parts of antioxidant, zonyl 0.2 parts of water-soluble carboxylate anionic fluorocarbon surfactant, 4 parts of calcium carbonate, 5 parts of talc, 9 parts of kaolin, 2 parts of dioctyl maleate, 6 parts of quartz powder, 0.4 parts of vulcanized powder, weight 11 parts of spar, 8 parts of emery, 16 parts of carbon black, 2 parts of alumina, 2 parts of cyclohexyl phthalate, 9 parts of aluminum hydroxide; go through the following steps:

[0077] a. Immerse the glass fiber bundle in the prepared water-soluble phenolic resin solution, and then pass the drying tower to dry it;

[0078] b. The tensioned glass fiber bundle is obtained by mechanical tensioning;

[0079] c. Put the above-mentioned rubber raw...

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...
