Definitions

  • the present invention relates to a multi-plate clutch arrangement with at least two friction clutches, which have lamellar packages arranged radially offset from one another on plate carriers, which are connected to clutch outputs and to a clutch basket as a drive, with pistons which serve to actuate the friction clutches.
  • the invention also relates to a device for assembling a multi-plate clutch.
  • Double clutches for a drive train are known, for example, from EP 2905492 B1.
  • Such clutch assemblies are used in motor vehicle drive trains to connect a drive motor, such as an internal combustion engine, to a transmission, such as a stepped transmission.

Agencement d'embrayage multidisque à unités multiples, l'agencement comprenant au moins deux embrayages à friction (K1, K2, K0) comportant des ensembles disques disposés de manière décalée radialement les uns par rapport aux autres, sur des supports de disques (9, 10, 11, 12) reliés à des sorties (63, 64) d'embrayage et à une plaque (60) d'embrayage en tant qu'entraînement, comportant des pistons (13, 14, 15) servant à actionner les embrayages à friction (K1, K2, K0). Au moins la plaque (60) d'embrayage et les sorties (63, 64) d'embrayage sont constituées de feuilles et sont maintenues à la fois axialement et radialement par des paliers axiaux (33A, 33B, 33C, 33D, 33E) et des paliers radiaux (34A, 34B, 34C) s'étendant sur des surfaces métalliques des feuilles et ancrés contre les feuilles.
