Embodiment Construction

[0032] In the ensuing description, the same numerals denote the same components or components having similar functions.

[0033] exist figure 1 A clutch disc 10 for a friction clutch of a motor vehicle is shown above.

[0034] The clutch disc 10 is in particular intended to be connected to an engine flywheel (not shown) of the motor vehicle and to be actuated via a membrane mechanism which itself is controlled via a stop (not shown).

[0035] As is known, the clutch disc 10 comprises an axial shaft seat 12 connected to a transverse support side plate 14 comprising a set of transverse support elements 16 elastically deformable in the axial direction.

[0036] These support elements 16 , for example blades, support annular friction linings 18 which are fixed axially on both sides of the set of support elements 16 by means of fastening rivets 22 .

[0037] Each lining 18 comprises at least a friction material 20 around an axis of rotation A extending in the axial direction, the...

Abstract

The invention relates to a friction lining (18) and a clutch disc (10) for a friction clutch of a motor vehicle comprising such a friction lining (18), comprising at least, about an axis of rotation (A) extending in the axial direction, a friction material (20) respectively comprising a friction surface (28) and an attachment surface (26), said material (20) being rotatably linked to a foil (24) comprising a proximal surface (30) adhered to the attachment surface (26) of the friction material (20) which is characterised in that the friction lining (18) comprises at least one recess (32) which, arranged axially between the friction surface (28) of the material (20) and the proximal surface (30) of the foil (24), is made in the friction material (20) in order to reduce the overall inertia of the friction lining (18).

Description

technical field [0001] The invention relates to a clutch disc and a friction lining comprising a friction material of reduced inertia glued to a metal foil. [0002] The present invention relates more particularly to a friction lining for a clutch disc, said friction lining comprising at least a friction material around a rotational shaft extending in an axial direction, the friction material respectively comprising a friction surface and a fixed surface, so The friction material is rotatably connected with the metal foil, and the metal foil includes a near side, and the near side is fixed to the fixed surface of the friction material by glue. Background technique [0003] Many examples of friction linings of this type are known for clutch discs. [0004] Patent document FR-1.304.067 describes and shows a clutch disc comprising friction linings of the type described above, ie each formed of friction material glued to a metal foil, respectively. [0005] Such friction linin...
