Embodiment Construction

[0037] figure 1 A dry friction lining according to the first embodiment of the present invention is shown. Said lining is indicated with the general numeral 10 and is intended to be fitted to a friction device of a motor vehicle clutch.

[0038] Said friction lining 10 is provided with a friction surface 12 for cooperating with a complementary friction surface 13 of a pressure or reaction plate 14 of said clutch in order to rotationally connect said friction means with said plate 14 clutch mechanism.

[0039] Preferably, the dry friction device includes two movable supports, the supports are connected to each other through axial damping components, and each support supports a friction lining 10, and the lining is respectively connected to the The pressure plate and the reaction plate cooperate.

[0040] figure 1 A slight parallelism defect between the friction lining 10 and the plate 14 is shown, which may exist in some cases.

[0041] In order to reduce the running-in ti...

Abstract

Said dry friction lining (10) comprises a friction surface (12) for interacting with a clutch pressure or reaction plate (14), wherein said friction surface (12) comprises projections (16) whose heights (H) are substentially identical. The heights of projections extend between substantially parallel top (18) and lower (20) planes. The surface area of the assembly parts (22) of the top plane (18) intersecting the projection (16) is equal to or less than 60 % the surface area of the part (24) of the lower plane (20) intersecting the lining (10). A dry friction device comprising said friction lining, a dry clutch comprising said device and a mould whose moulding surface is shaped in such a way that it is complementary to the friction surface (12) of the friction lining (10) are also disclosed.

Description

technical field [0001] The present invention relates to a dry friction lining for a dry clutch friction device of a motor vehicle, a dry friction device, a dry clutch and a mold for molding the friction lining and a method of rodage for such a friction lining, wherein The dry friction device includes a friction lining of this type, and the dry clutch includes a friction device of this type. Background technique [0002] Motor vehicle clutches are used to transmit torque between the motor vehicle engine flywheel and the input shaft of the gearbox. To this end, the clutch comprises a mechanism that is rotationally connected to the engine flywheel and a friction device that is rotationally connected to the gearbox shaft. [0003] A distinction is usually made between dry friction linings for fitting in dry clutches ("dry clutch" in English) and wet friction linings for fitting in oil-soaked clutches ("wet clutch" in English). [0004] The dry friction lining works in an air e...
