Abstract

A clutch system for a transmission with one clutch (1) which comprises one disc carrier (3) and one servo mechanism (10) situated within the disc carrier (3) with dynamic pressure balance for actuating the clutch (1) and with a planet carrier of a planetary gear set (26) the spider plate (27) of which abuts in axial direction on a pressure balance space (15) of the dynamic pressure balance of the servo mechanism (10). It is proposed that the spider plate (27) be non-torsionally connected with the disc carrier (3) and be axially fixed via a locking element (31) on the disc carrier (3) in a manner such that the servo mechanism (10) is prestressed against the disc carrier (3) by the axial fixing of the spider plate (27).
