Description

Technical Field

[0001] The utility model relates to the technical field of clutches, in particular to a rubber-coated composite wire reinforced automobile clutch face sheet. Background Art

[0002] The clutch is a component in the automobile transmission system that is directly connected to the engine. It is responsible for the cutting and connecting of the power and transmission system. The clutch is mainly operated through the clutch facing plate. The clutch facing plate is composed of a friction plate and a lining plate. During the working process, the clutch function is realized by the contact and separation of the active friction plate and the driven friction plate. The clutch facing plate is generally prepared by a process route of mixing, dissolving, dipping, drying, pressing, and heat treatment. During the production, the skeleton material of the friction plate is generally made of cord cloth or a composite fiber mixed twisted line.

[0003] Existing friction plates such as Figure 1 As shown, it is an integrated plate body. When installing the friction plate, it is necessary to drill holes on the friction plate, and then fix the friction plate and the lining plate with rivets. When drilling holes in the friction plate, there is a risk of damaging the friction plate skeleton material, and when the drilling is not standardized, it will also cause the friction plate to have imperceptible cracks, thereby affecting the mechanical strength of the friction plate and making the friction plate's pressure resistance worse. When the pressure plate in the clutch squeezes the friction plate, the friction plate is easily damaged, and when the integrated friction plate is partially damaged, the entire friction plate needs to be replaced. In this process, all the rivets on the friction plate need to be removed, and the replacement efficiency is low and the cost is high. Utility Model Content

[0016] 1.

[0029] Please refer to the attached Figure 2 , Figure 3 The assembly plate 31 is a sector-shaped plate whose inner diameter and outer diameter are respectively the same as those of the lining 1. A plurality of assembly plates 31 are arranged above the lining 1 and enclose a circular ring plate which is the same as the lining 1. The mounting holes 32 are arranged outside the assembly groove 33, specifically on both sides of the assembly groove 33.
