Abstract
An inner disc carrier (LT) for a wet-type friction clutch (K) may have a driving toothing including ridges (S, SX) and grooves (N) for the form-locking accommodation of discs (L) of the friction clutch (K). Each of a first group of the ridges (S) has a first opening (A) produced in a chip-less shaping process and a section (ST) extending radially inwardly at the first opening (A) and created during production of the first opening (A). Hydraulic fluid supplied radially from inside the inner disc carrier (LT) from a first axial position is guided through the first openings (A) to the discs (L). Hydraulic fluid supplied radially from inside the inner disk carrier (LT) from a second axial position is guided past the discs (L). The sections (ST) of the ridges (S) act as a damming contour for hydraulic fluid supplied radially from the second axial position.
