Embodiment Construction

[0044] figure 1 is a sectional view of a wet friction clutch 2 comprising a friction pack 1 consisting of an inner disc carrier 3 and an outer disc carrier 4 . The inner disk carrier 3 and the outer disk carrier 4 each have a plurality of first disks 6 and second disks 7 . The first friction plate 6 and the second friction plate 7 are located in the friction plate chamber 5. Formed in the first lining carrier 3 is a first through-opening 9 through which coolant can enter, pass through the first lining carrier 6 and the second lining 7 and return along the outer lining carrier 4 and again through the second lining carrier Two through openings 10 enter the friction lining chamber 5 . A feed line 24 to the friction lining chamber 5 , which is statically sealed by a first static seal 31 and a second seal 32 , is connected to the first through-opening 9 . In the partial schematic view of the wet friction clutch 2 , only the central shaft 8 is schematically shown, around which th...

Abstract

The invention relates to a friction pack for a wet friction clutch having at least the following components: an inner disc carrier; an outer disc carrier; a disc chamber for accommodating the discs for friction-locking transmission of torque; a central shaft, the The friction plate carrier can rotate around the central axis, wherein the internal friction plate carrier has a first through opening and a second through opening, the first through opening extends from the central axis to the friction plate chamber, and the second through opening An opening extends from outside the friction lining chamber to the friction lining chamber. With the proposed wet friction clutch or friction pack, the cooling power of the coolant can be used more effectively and the required installation space and production costs can be reduced.

Description

technical field [0001] The present invention relates to a friction assembly for a wet friction clutch, and a wet friction clutch having such a friction assembly. In particular, the friction assembly or the wet friction clutch can be used in a motor vehicle with an internal combustion engine or an electric motor. In this case, the friction pack or wet friction clutch is suitable for detachably connecting a rotating input shaft with a stationary or slowly rotating output shaft. Background technique [0002] Frictional heat is generated when connecting two shafts with different rotational speeds. In order to be able to dissipate this heat adequately, the friction pack or wet friction clutch must be designed with sufficient thermal mass. If the friction clutch is designed dry, ie without coolant, the thermal mass is formed by structural parts of the friction clutch or of the friction pack. However, such dry friction clutches are not suitable for many applications because they...
