Embodiment Construction

[0052] figure 1 A prior art friction disc 1 is shown having a splined hub 2 extending along an axis A for coupling to an input shaft of a transmission connected to a flange extending radially outwards from the splined hub 2. Lan Pan3. Annular friction linings 4 are installed on both sides of the flange 3 at the radially outer periphery of the flange.

[0053]Each friction lining 4 has a supporting member, which is formed by an annular sheet 5, that is, a sheet of composite material or a thin sheet of metal material, the thickness of which is generally between 0.2 mm and 1 mm.

[0054] The annular friction body 6 is installed on the surface of the sheet body 5 facing away from the flange 3 . The friction body 6 generally consists of fiber material, binder and filler, as is known inter alia from document FR 2 941 758 in the name of the applicant.

[0055] Each friction body 6 has a radial fixed surface 7 facing the side of the corresponding plate body, and a radial friction s...

Abstract

The invention relates to a method for the production of a clutch friction lining (4), comprising the following steps consisting in: producing a friction body (6) including at least one hole (10) that opens only at a first surface (7) of the body (6); attaching the friction body (6) to a support (5) by adhering the first surface (7) of the body (6) to the support (5); and machining a second surface (8) of the friction body (6), opposite the first surface (7), until the aforementioned hole (10) opens at the second surface (8) of the friction body (6).

Description

technical field [0001] The invention relates to a method for producing a friction lining for mounting on a friction disk of a motor vehicle clutch, in particular a dual clutch. Background technique [0002] A dual clutch can alternately engage a motor vehicle engine shaft with two coaxial input shafts, which may be of an automated type transmission. [0003] Thus, a dual clutch can change gear ratios while maintaining engine torque transmission to the vehicle wheels. In fact, two clutches are connected to the even and odd gear ratios respectively. When changing gear ratios, the first clutch is disengaged and the second clutch is engaged such that engine torque is gradually transferred from the first clutch to the second clutch. [0004] Each clutch includes a mechanism that includes a diaphragm for cooperating with a pressure plate that rotates integrally with the motor shaft and cover. Each diaphragm is movable between a rest position and an active position using a corre...
