摘要： The invention relates to a wet multi-plate clutch, in particular for automatic transmissions in motor vehicles, comprising annular clutch plates which are arranged in a clutch housing and are alternately subdivided into steel plates and friction disks. A radially external toothed section of the steel plates is positively connected to the clutch housing in the circumferential direction, while a radially internal toothed section of the friction disks is positively connected to a shaft or hub. The friction disks have grooves which discharge oil radially outward, and the steel plates have recesses. In order to reduce a potential drag moment when the multi-plate clutch is disengaged, the recesses (18, 20a to 20c) are incorporated into at least some of the teeth of the toothed section (14a) in a substantially radial direction outside the effective, annular frictional surfaces (14b) of the steel plates (14).
