Embodiment Construction

[0049] figure 1 A dual clutch 1 with friction clutches 2 , 3 arranged around a rotational axis 4 of transmission input shafts 6 , 7 of a transmission 5 is shown. The friction clutches 2, 3 are composed of a central pressure plate 8 and pressure plates 11, 12 each movable relative to a friction surface 9, 10, wherein between the friction surfaces 9, 10 and the pressure plates 11, 12 facing these friction surfaces Friction plates 13 , 14 of clutch disks 15 , 16 are arranged between the friction surfaces, and the clutch disks are each non-rotatably connected to a transmission input shaft 6 , 7 , eg toothed. In the illustrated embodiment, the pressure plates 11, 12 are acted upon by the transmission elements 17, 18, which are radially inwardly actuated by the actuating devices 19, 20 of the operating system 21 directly and without the leverage of the transmission elements 17, 18. Towards the movement, so that on the pressure plate 11, 12 by means of the transmission part 17, 18 ...

Abstract

The invention relates to a dual clutch (1,101,201,301,401) having two friction clutches (2,3), having a central pressure-exerting plate (8) and having two pressure plates (11,12,111,112,311,312) which are axially movable relative to said pressure-exerting plate (8) with the interposition of the friction linings (13,14) of two clutch disks (15,16), which mesh with in each case one gearbox input shaft (6,7), of actuating devices (19,20). The dual clutch (1,101,201,301,401) is held at the drive-input side, with the dual clutch (1,101,201,301,401) being supported at the gearbox side by means of an actuating system (21,321), which holds the two actuating devices (19,20), for actuating the pressure plates (11,12,111,112,311,312), and with the actuating system (21,321) being rotatably held on the clutch housing (25,125,325,425).

Description

technical field [0001] The invention relates to a double clutch with two friction clutches driven by a drive unit, which are provided with a common clutch housing, a pressure plate with two pressure surfaces fixedly connected to the housing, and two respective Axially movable pressure plate towards a pressure bearing surface. Background technique [0002] Double clutches are known which have two friction clutches with a clutch housing and a central pressure plate fixedly connected to the housing. The pressure plate is moved by the actuating device in that radially inwardly a disk spring or a lever element is axially loaded with a predetermined clutch travel. In this case, it depends on whether the friction clutch belongs to the configuration of forced compression or forced opening, that is, forced closing or pressurization, or forced pulling, that is, forced opening. The lever is supported on the clutch housing and constitutes a lever ratio, so that the axial stroke of the...
