Embodiment Construction

[0027] Referring to this figure, it can be seen that a normally open dual clutch is chosen as an example.

[0028] It must be noted, however, that the invention is in no way limited to such clutches, and that the invention is generally applicable to dual and multiple clutches, as well as normally open and normally closed clutches.

[0029] refer to figure 1 , it can be seen that the dual clutch includes an inner output shaft 1 coaxially installed inside the outer output shaft 3 .

[0030] Two friction disks 5, 7 are mounted fastened respectively to the two shafts 1, 3 and each friction disk comprises a respective friction lining 9, 11 at its periphery.

[0031] The discs 5, 7 each comprise alarm damping means 8a, 8b, known per se, for damping vibrations transmitted from the crankshaft to the clutch.

[0032] The liner 9 is arranged between the support plate 13 fixed in axial translation and the pressure plate 15 capable of axial translation.

[0033] Liner 9 is associated w...

Abstract

The invention relates to a multiple clutch assembly comprising: first (5, 9) and second (7, 11) friction elements; first (15) and second (17) plates for applying pressure to said respective friction elements; first (21) and second (25) diaphragms for actuating said respective plates, each diaphragm being mobile between a disengaged position (21a, 25a or 25b) and an engaged position (21b or 21c, 25c), said first diaphragm (21) approaching the second diaphragm (25) when it passes from the disengaged position thereof to the engaged position thereof; and first (23) and second (27) means for actuating said respective diaphragms. Said second actuating means (27) comprise means for renewing the course of the second diaphragm (25), in such a way that the second diaphragm (25) follows a pre-determined course between the disengaged position (25a or 25b) and the engaged position (25c) thereof, independently of the degree of wear of the second friction element (7, 11).

Description

technical field [0001] The invention relates to a multiple clutch assembly, in particular for a motor vehicle, and to an associated control method. Background technique [0002] As known per se, a multi-clutch assembly comprises several clutches, and usually two clutches. [0003] This clutch pack is particularly advantageous in changing gears without interruption of torque. [0004] However, a disadvantage of this clutch assembly is that the axial dimension is larger than that of a single clutch. [0005] Again, this axial dimension is a critical factor in mounting the clutch pack between the engine and gearbox of a particular vehicle. Contents of the invention [0006] It is therefore an object of the present invention to provide a multi-clutch assembly which has a smaller axial dimension than the multi-clutch assemblies currently available on the market. [0007] The object of the present invention is achieved by means of a multi-clutch assembly comprising: [0008]...
