However, in the above two friction clutches, the automatic detection of the thickness of the friction lining depends on the movement of the detection spring lever. This indirect detection method will be affected by the mechanical characteristics of the spring lever, leaf spring and clutch cover. , there is a risk of unreliable

Embodiment Construction
[0022] figure 1 A schematic half-sectional view of a friction clutch according to a preferred embodiment is shown.
[0023] Friction clutches are used, for example, in vehicles for the controlled transmission of the torque delivered by the internal combustion engine to the transmission. The friction clutch according to the present embodiment is designed as a normally open clutch. The friction clutch has a mating plate 1 , a friction disc 3 and a pressure plate 2 arranged in succession along the same axis of rotation X. The friction clutch also has a clutch cover 4, which is connected to the mating plate 1 at the radially outer end by bolts. The clutch cover 4 is in the shape of a bell jar, whereby the clutch cover 4 together with the mating plate 1 forms a space for accommodating the friction disc 3 and the pressure plate 2 .
[0024] Counterplate 1 can be connected to the crankshaft of the internal combustion engine, not shown, in order to transmit the torque of the intern...

The invention relates to a friction clutch and a clutch system. The friction clutch comprises: a pressing plate (2), a matching plate (1), a spring lever (5) and a self-compensating adjusting mechanism, wherein the pressing plate (2) and the matching plate (1) are arranged coaxially and can jointly rotate about an axis of rotation (X); the spring lever (5) can act on the pressing plate, so that the pressing plate moves axially towards or away from the matching plate; the self-compensating adjusting mechanism comprises an adjusting ring (8), a ratchet wheel (10), a rotary reversing assembly and a driving spring (11); and when the friction clutch is connected, if reduction of the distance between the matching plate and the pressing plate exceeds a threshold value, a pawl of the driving spring can drive the ratchet wheel to rotate when the friction clutch is connected or disconnected again, and the adjusting ring rotates relative to the pressing plate and the spring lever, so that the axial distance between the spring lever and the pressing plate is adjusted. The clutch system comprises at least one friction clutch.
Description
technical field [0001] The invention relates to a friction clutch, in particular to a friction clutch with a self-compensating adjustment mechanism. The invention also relates to a clutch system having a friction clutch as described above. Background technique [0002] Conventional clutches change their characteristics as they wear. It is thus advantageously possible to provide a self-compensating adjustment mechanism in the automated friction clutch. Self-compensating adjustment of the clutch generally means that the clutch will compensate itself in some way throughout the life of the friction lining wear, so that the clutch characteristics change as little as possible or even keep the clutch characteristics constant. [0003] One possible configuration is a load regulating clutch. This type of self-compensating regulation compensates by destroying and rebuilding its load balancing system, the point of which is mainly to keep the load balancing system "as stable as possi...
