Problems solved by technology

The disadvantage of this type of lubricant accumulation is, on the one hand, that a certain tractive force is generated between the outer and inner friction lining due to a certain backflow of the lubricant and the possibility of a traction (schleppenden) connection between the outer and inner friction linings moment

Embodiment Construction

[0023] figure 1 The outer disk carrier 1 according to the invention is shown, in the exemplary embodiment shown, the rotor 2 of the electric machine 3 is connected to the outer disk carrier. As in known solutions, the outer disk carrier 1 is usually part of a known hybrid clutch, which is radially integrated via an annular carrier section 4 and an axially extending bearing section 5 . The position is rotatably supported by the rolling bearing 6.

[0024] In known variants, internal toothing 7 is formed on the outer disk carrier 1 , wherein, for the sake of clarity, only the toothing 8 is shown in the sectional view, and not the other toothing rows which are still visible in the sectional view. exist figure 2 The two toothings 8 of the inner toothing 7 are shown in the sectional view along the section line II-II shown in . The teeth 8 are each spaced apart from one another by a groove 9 , wherein the teeth 8 and the grooves 9 extend over the entire length of the outer disk ...

Abstract

A clutch device, the clutch device includes at least one axially extending outer friction plate support and a plurality of outer friction plates, wherein the outer friction plate support includes axially extending inner teeth, and the inner teeth have a plurality of axially extending grooves spaced apart from each other, the outer lining has outer teeth that engage in the above-mentioned inner teeth, wherein the geometry of the respective groove bottom is designed in such a way that the lubricant accumulated in the groove bottom when the outer disk carrier rotates Can be conveyed axially along the groove.

Description

technical field [0001] The invention relates to a clutch device comprising at least one axially extending outer friction plate support and a plurality of outer friction plates, wherein the outer friction plate support comprises axially extending inner teeth, the inner teeth having shafts A plurality of teeth portions spaced apart from each other toward the extending grooves, the outer friction plate has outer teeth meshing with the inner teeth. Background technique [0002] Such clutch devices are used, for example, in clutches of motor vehicles and can be designed in various ways. For example wet single clutches or double clutches are known, in which one clutch device is provided in the single clutch and two clutch devices are provided in the double clutch. Hybrid clutches are also known, which enable the selective connection of an internal combustion engine or an electric machine to a subsequent transmission, wherein, in this case, the rotor of the electric machine is con...
