Embodiment Construction

[0022] figure 1 The readjustment device 1 of the friction clutch in the closed state is schematically shown in a sectional view. The pressure plate 3 , which is non-rotatably connected to the clutch housing 2 and axially by means of an energy store, not shown, such as a leaf spring, is clamped at a distance 5 relative to a pressure plate 4 arranged fixedly to the housing. This distance corresponds to the thickness of the friction linings of the clutch disc (not shown) in the clamped state, which is represented by the operating point 6 . The pressure plate 3 is acted upon by a lever system 7 pivotably mounted on the clutch housing 2 with a pressure force whose magnitude is applied on the other side of the lever system with a disengaging system (not shown) for actuating the friction clutch. to measure. In the exemplary embodiment shown, this is a so-called press-on friction clutch with a double-arm lever system 7 , for example a disk spring, which is not loaded in the shown c...

Abstract

The invention relates to a friction clutch, at least comprising a clutch housing having a pressure plate that can be displaced thereon non-rotatably and axially limited, wherein said pressure plate can be subjected by a lever system supported on the clutch housing to a contact force that is counter to the effect of energy accumulators acting between the clutch housing and the pressure plate with respect to a pressure plate fixed on the cover, while tensioning the friction linings of a clutch plate. To this end, wear of the friction linings is compensated for in that a resulting first distance between the pressure plate and lever system is compensated for by way of a rotation of a ramp system, which is disposed between the pressure plate and lever system, using a rotational device if, while the pressure plate is subjected to a maximum force by the lever system, a second predetermined distance is determined between the pressure plate and clutch housing, said second distance exceeding a predetermined value, and a rotation occurs during an alleviation of the pressure plate by the lever system and a displacement of the pressure plate occurs by means of the energy accumulators active between the pressure plate and the clutch housing.

Description

technical field [0001] The invention relates to a friction clutch with a pressure plate and a limited displacement in the axial direction relative to the pressure plate, loaded by a lever system, for establishing a friction fit with the friction plates of a clutch driven plate The pressure plate, wherein, depending on wear, readjustment of the friction clutch is achieved by readjustment of this lever system. Background technique [0002] Friction clutches with readjustment devices are known. Such a readjustment device can be realized, for example, force-controlled. Adverse wear-related changes in the contact force of a lever system, for example a disc spring, which acts on the pressure plate of the friction clutch due to wear are detected and readjusted as a function of this contact force. Alternatively, the error distance between the clutch housing and the lever system which occurs when the friction linings of the clutch disc wear is ascertained and corrected according to...
