Embodiment Construction
[0032] figure 1 Shown in partial section is a friction clutch 1 arranged around an axis of rotation 4 with a housing 2 and a counterplate 3 fixedly received on the housing, indicated only schematically, axially displaceable by a disc spring 5 The pressure plate 6 , which is connected in a rotationally fixed manner to the housing 2 , can be biased against the counter pressure plate in a frictional engagement with a friction lining 7 of a clutch disk (not shown in detail).
[0033] In order to compensate for axial wear of the friction lining 7 , an adjusting ring 8 is arranged between the disk spring 5 and the pressure plate 6 , which is twisted by the spindle drive 9 when wear is detected. For this purpose, if an increased axial travel of the pressure plate 6 relative to the housing 2 occurs due to wear, the pinion 10 connected to the lead screw of the screw drive 9 and received on the housing 2 in the worn state Form-locking is established between the drive pawls 11. During...

The invention relates to a friction clutch at least comprising a housing, which is arranged about a rotational axis and which has a contact plate, which is arranged so as to be movable relative to energy stores in a rotationally-fixed and axially-limited manner against the effect of the energy stores and which can be moved axially by a disk spring to be supported on the housing relative to a counterpressure plate arranged rigidly with respect to the housing in order to clamp friction linings of a clutch disk, wherein if a distance between the contact plate and the counterpressure plate formed when friction linings are clamped is fallen below, a form fit between a pinion, which is connected to a spindle of a spindle drive arranged on the contact plate for rotationally driving an adjustment ring that is arranged between the contact plate and the disk spring and that has ramps arranged in the circumferential direction and facing the contact plate, and a drive pawl, which is fastened to the housing elastically under preloading in the direction of the contact plate, is formed and is released during an actuating motion of the contact plate relative to the housing after a rotation of the pinion by means of the drive pawl. In order to compensate a press-on force that changes over the wear range of the clutch disk, more or less cam height is compensated compared to the lining wear that has actually occurred - depending on the course of the press-on force characteristic curve - so that the operating point of the clutch is shifted in a specific manner. Likewise, by means of a "freeform" of the stop ramp, more compensation can be provided up to certain range compared to the lining wear that has actually occurred, and then less compensation can be provided compared to the lining wear that has actually occurred.
Description
technical field [0001] The invention relates to a friction clutch and a method for assembling the friction clutch, the friction clutch comprising at least one housing with a pressure plate which is torsion-proof and axially limitedly displaceable relative to the housing, the pressure plate It can be axially displaced by the disk spring supported on the housing relative to the counter pressure plate fixed on the housing under the condition that the friction lining of the clutch plate is clamped, wherein, when lower than in the friction lining clamped state When the distance formed between the pressure plate and the counter pressure plate is reduced, a positive fit is formed between the pinion and a drive pawl and after the pinion has been twisted by means of the drive pawl during the operational movement of the pressure plate relative to the housing The form-locking is released and the pinion is connected to the lead screw of the screw drive arranged on the pressure plate for t...
