Embodiment Construction

[0038] especially from figure 1 The general construction of the clutch arrangement according to the invention can be seen in . The clutch device shown here comprises, arranged about a common axis of rotation 1 , an inner disk carrier 10 and an outer disk carrier 30 , said inner disk carrier having a plurality of first friction disks arranged rotationally fixed thereto. 20, the outer disk carrier has a plurality of second friction disks 40 arranged rotationally fixed thereto.

[0039] The first friction plate 20 and the second friction plate 40 together constitute a plate group 50 .

[0040] Furthermore, the clutch device comprises a hub element 60 which is connected in a rotationally fixed manner to the inner disk carrier 20 by means of a plurality of leaf springs 70 . The further connection between the hub element 60 and the inner disc carrier 20 is realized by means of stepped screws 80 .

[0041] Furthermore, the clutch device includes a counterplate 100 which is centered ...

Abstract

The invention relates to a clutch device and a drive train. According to the invention, the clutch device comprises an inner plate support (10) and an outer plate support (30); at least one first friction plate (20), which is arranged on the inner plate support (10) in a torque-interlocking and axially movable manner; at least one second friction plate (40), which is arranged on the outer plate support (30) in a torque-interlocking and axially movable manner, wherein the first friction plate (20) and the second friction plate (40) together form a plate pack (50); a force exertion device for exerting an axial contact pressure on the friction plates (20 and 40); a hub element (60), which is connected to the inner plate support (10) by means of leaf springs (70) in a substantially rotationally fixed manner, wherein a first end (71) of each leaf spring (70) is mechanically fixed to the hub element (60) and the other, second end (72) thereof is mechanically fixed to the inner plate support(10); and wherein one of the connections of each leaf spring (70) is provided on a corresponding connecting component by means of a step pin (80), and the step pin (80) is guided in a manner movable axially in translation in the other component, connected by means of the leaf spring (70), and the end of the step pin (80) opposite the fixing to the component has a pin head (81) having a greater radial extent than an opening (11) in the component guiding the step pin (80) in translation. The invention thus relates to a clutch device which ensures centering of the leaf spring core (90) in relation to the counter-plate (100) and facilitates assembly.

Description

technical field [0001] The invention relates to a clutch device and a drive train for a motor vehicle. Background technique [0002] Especially for applications in motorcycles, leaf spring clutches have been pioneered. However, implementing the process for component manufacturing is relatively complex. Sheet carriers are usually produced by means of a roll-forming process, which leads to the use of complex tools and a relatively high energy requirement. [0003] Clutch devices are known from two documents WO 2016 / 131450 A1 and WO 2016 / 082832 A1, in which the plate carrier is connected substantially rotationally fixed to the hub element via a leaf spring. The leaf springs are used here for the axial force loading of the disk pack for the frictional transmission of torque within the clutch device. [0004] Likewise, it is known from WO 2014 / 139526 A1 to provide a spring mechanism between the input side and the output side branch of the clutch device in order to increase the...
