Embodiment Construction

[0047] Figures 1 to 5 A cover assembly 1 according to a first embodiment of the invention is shown. exist figure 1 It can be seen in the cover assembly 1 in a sectional view parallel to the axial direction or displacement direction 2 .

[0048] figure 1 Cover 3 is shown in . The cover 3 is a molded member. In particular, the cover section 4 and the holding section 5 are shown, both of which are formed in one piece from the sheet metal part forming the cover 3 by means of sheet metal forming. Arranged radially outside the holding section 5 are two wire rings 6 , a disk spring 7 and a spring element 8 . The spring element 8 is currently arranged between the cover-side wire ring 6 and the cover section 4 , ie at figure 1 On the side of the right-hand wire loop 6 facing away from the disc spring 7 . The disc spring 7 is an actuating element within the meaning of claim 1 .

[0049] The holding section 5 extends substantially away from the cover section 4 in the axial direc...

Abstract

The invention relates to a cover assembly (1) for a motor vehicle clutch, said assembly comprising an actuating element (7), such as a diaphragm spring, said element being provided to come into contact with a pressure plate (10), the actuating element (7) being in contact with a cover (3) via at least one wire ring (6). At least one spring element (8), the cross-section of which is substantially V-shaped when unstressed and substantially C-shaped when pre-stressed, lies on the wire ring (6) in order to pre-stress said wire ring (6) in an axial direction, such that during the pre-stressing process limbs of the substantially V-shaped cross-section slide along an external surface of the wire ring (6) during the transition into the substantially C-shaped cross-section.

Description

technical field [0001] The invention relates to a cover assembly for a clutch / friction clutch of a motor vehicle, with an actuating element, such as a disk spring, which is intended to come into contact with a pressure plate, wherein the actuating element is connected to the cover via at least one wire loop cling to. Background technique [0002] Clutches are generally used in the drive train of a motor vehicle to couple an internal combustion engine to at least one drive wheel or to decouple it from said drive wheel. For this purpose, a clutch is usually arranged between an output shaft of the internal combustion engine, such as a crankshaft, and an input shaft of a transmission, which is operatively connected to at least one drive wheel. Usually the pressure plate is connected in a rotationally fixed manner to the crankshaft. Usually the clutch disk is connected to the transmission input shaft in a rotationally fixed manner and in an axially displaceable manner. The clu...
