Friction plate group and disc clutch or dis brake

A friction plate group (16, 18) for a multi-plate clutch or a multi-disc brake is described in the invention. The friction plate group (16, 18) comprises at least one inner friction plate (28) which can be coupled in rotation with an inner friction plate carrier, at least one outer friction plate (26) which can be rotationally coupled to an outer friction plate carrier, and a first axially outer amplifier ring (22). In this case, the inner friction plate (28) lies along a friction plate group axis (46) between the first amplifier ring (22) and the outer friction plate (26) and the amplifier ring (22) is connected to the outer friction plate (26) via one or more lugs (40) extending from the amplifier ring (22). In addition, a multi-disc clutch or multi-disc brake with such the friction plate group (16, 18) or more axially juxtaposed friction plate groups (16, 18) are presented. 本发明描述了种用于片式离合器或片式制动器的摩擦片组(16，18)。摩擦片组包括至少个与内摩擦片载体能转动耦联的内摩擦片(28)、至少个与外摩擦片载体能转动耦联的外摩擦片(26)和在轴向上位于外侧的第增强环(22)。在此，所述内摩擦片(28)沿着摩擦片组轴线(46)位于
