Fluid conducting assembly for a multi-plate clutch and clutch unit

A clutch unit for a driveline of a motor vehicle, comprising:

• a fluid guide assembly including an inner disk carrier with a longitudinal axis and with a carrier portion, a shoulder portion, and a shaft portion, wherein the carrier portion comprises a connecting structure with projections and recesses distributed over the circumference, and radially outside, to receive inner disks with a corresponding counter structure in a rotationally fixed and axially movable manner, with the fluid guide assembly further including a fluid guide element which is axially fixedly connected to the inner disk carrier, the fluid guide element having an annular catch portion in which inflowing fluid can be caught, and a plurality of circumferentially distributed tab portions which extend in axial direction and which each have a radial through-opening;
• wherein the inner disk carrier at a radially outer side comprises a plurality of longitudinal grooves over the circumference which extend axially from the shoulder portion into the carrier portion;
• and wherein the tab portions of the fluid guide element cover the longitudinal grooves of the inner disk carrier so that a channel for the fluid is respectively formed between them,
• the clutch unit further comprising:
• a wet friction disk clutch comprising an outer disk carrier in which a disk pack composed of outer disks and inner disks is arranged;
• a support plate against which the disk pack is axially supported;
• an axially movable pressure plate for axially acting on the disk pack;
• and
• an actuating device for operating the friction disk clutch by axially moving the pressure plate;
• wherein the inner disk carrier is rotatably supported about the axis of rotation relative to the outer disk carrier;
• and
• wherein inner disks of the disk pack are connected to the connecting structure of the inner disk carrier in a rotationally fixed and axially movable manner, so that when the inner disk carrier rotates, oil flows from the catching portion along the inner wall of the fluid guide member to the tab portions to lubricate the disk pack,
• wherein the inner disk carrier is rotatably supported in a housing, and wherein the housing includes a sleeve extension which extends axially into the annular space of the fluid guide element, thereby forming a fluid labyrinth.

• and
• a fluid guide element which is axially fixedly connected to the inner disk carrier, the fluid guide element having an annular catch portion in which inflowing fluid can be caught, and a plurality of circumferentially distributed tab portions which extend in axial direction and which each have a radial through-opening;
• wherein the inner disk carrier at a radially outer side comprises a plurality of longitudinal grooves over the circumference which extend axially from the shoulder portion into the carrier portion;
• and
• wherein the tab portions of the fluid guide element cover the longitudinal grooves of the inner disk carrier so that a channel for the fluid is respectively formed between them,
• wherein the longitudinal grooves extending axially from the shoulder portion into the carrier portion comprise radially inwardly directed recesses in the shoulder portion and are closed in the axial direction at an end opposite to the shoulder portion.
