Embodiment Construction

[0045] [45] For the sake of clarity, the dimensions of the various elements shown in the drawings are not to scale with their real dimensions. Like numbers correspond to like elements throughout the drawings.

[0046] [46] Within the scope of the present invention, the terms "axial", "axially" and "radial", "radially" are defined in relation to the axis of rotation of the friction disk. "Axial" refers to a direction parallel to the axis of rotation, while "radial" refers to a direction perpendicular to and passing through the axis.

[0047] [47] "Inner" refers to an area close to said axis of rotation, while "outer" refers to an area radially away from said axis of rotation.

[0048] [48] figure 1A schematic front view of a friction disc 1 is shown, said friction disc 1 comprising: a hub 5 that can be coupled to a driven shaft, a friction lining 3 and a cover sheet 2 shown in dotted lines. The elastic part, in particular the spring 4, is arranged so that vibrations from the...

Abstract

The present invention discloses the piece has rectangular tabs (62, 63) radially extended from a crown towards exterior, where the piece is formed of sheet iron. An internal radius of the crown is close to that of a friction lining (3). A radial width of the crown is less than or equal to 20 percentages of a radial width of the piece. The tab (63) is in sliding contact with a part of a flange of a web (2), and the tab (62) is fixed to another part of the flange. Independent claims are also included for the following: (1) a friction disk for a dry clutch (2) a method for manufacturing a friction disk.

Description

technical field [0001] [01] The present invention relates to a dry clutch friction disc, and more particularly to a dry clutch friction disc for motor vehicles. Usually, a clutch friction plate is used to be mounted on a so-called driven shaft and interposed between a clutch reaction plate and a pressure plate rotatably coupled to the drive shaft. The pressure plate presses the friction disc against the reaction plate when the clutch is operated. Background technique [0002] [02] Although applicable to any type of friction disc, the invention is particularly advantageous for so-called progressive clutch discs. [0003] [03] For example, a progressive clutch friction disc shown in accompanying drawings 7 and 8 of the patent FR1304067 includes a metal support in the shape of a substantially flat ring crown, usually called a "cover sheet (voile)", and the ring crown The outer circumference of the ring is divided into pieces so as to have fins joined or attached to the ring c...
