Abstract:
An automatically adjusting clutch (10) in which a pressure plate (13) is biased axially towards a flywheel (11) by a main clutch engaging spring (12) to clamp a driven plate between the pressure plate and flywheel to engage the clutch. A first part (30) of the pressure plate is moveable by an adjuster relative to a second part in the form of a pivot ring (40) of the pressure plate to increase the effective axial thickness of the pressure plate to compensate for the wear of the driven plate. The adjuster having an array of adjuster teeth (44) which are disposed circumferentially around the pivot ring (40) and one or more pawls (60) which move relative to and in contact with the array as the pressure plate moves relative to the flywheel. The pawl(s) and array are arranged so that if movement of the pressure plate towards the flywheel during clutch engagement exceeds a predetermined distance, indicating a predetermined amount of wear of the driven plate, the pawl(s) move sufficiently over the array to engage behind a tooth of the array so that subsequently the pawl(s) move the first part of the pressure plate relative to the second part to make the wear adjustment.
Abstract:
A friction clutch comprising a pressure plate (120) consisting of two plate halves (120A, 120B) that are mutually axially movable by means of a wear adjustment device (111) including at least one pair of complementary ramps (190, 191), a setting element (101) rotatable relative to an adjustment ramp (190) between two positions of which one corresponds to a worn state of the friction linings (130), resilient setting means biasing the setting element (101) towards said position, and first locking means (112) for rotationally locking the setting element (101) relative to the pressure plate (120), which means may be disabled by locking means (212) that can rotationally lock said adjustment ramp (190) relative to the pressure plate (120) and may be disabled by a release element (103) arranged in such a way that the first (112) and second (212) locking means are successively enabled as the clutch is disengaged and engaged.
Abstract:
An adjusting mechanism for a clutch control cable (1, 2) includes a rod (5) which passes through a tiltable, apertured plate (14) which is operable by a clutch pedal (4) which has a captive roller (4a) engaging the plate (14). The pedal is depressed to disengage the clutch and tilts the plate (14) which engages the rod (5) and pulls the cable core (1). A helical compression spring (16) acts between the plate (14) and a washer (12) to adjust the rest position of the rod and then bring the assembly into proper adjustment. The rest position of the rod can be defined by a sliding stop (figures 2 to 5) which can operate electrical contacts (figure 10). Two springs can be used, for adjustment and for biasing the apertured plate (figures 8 and 9). The adjuster may be in-line (figures 12 to 14).
Abstract:
The disclosed cover comprises a substantially cylindrical hollow body (2), an elastic compensating membrane (3) and a compensating spring (16). The hollow body (2) has at one of its ends (CŸ ) an inlet to which is coupled the functional extremity (5) of a hydraulic cylinder (CŸ ), and at the other end a closure face (10). The membrane (3) has a retaining extension (9) for its secured positioning and prevents the liquid (FŸ ) contained in the cylinder (CŸ ) to leak to the outside. The helical spring (16) actuates permanently in a compression mode and one of its ends bears against the inside of the closure face (10) while its other end bears against the internal face (9) of the membrane (3). The membrane (3) and the hollow body (2) define a compensation chamber (15) whose volume (VŸ CŸ ) varies as a function of the pressure exerted by the fluid (FŸ ) on the external face (8) of the membrane (3). Application to the motor vehicle industry.

Abstract:
A friction clutch (1) has a pressure plate (3), a cup spring (4), a release bearing cup (22) and an automatic, continuous adjustment means (16) located inside the housing (2). The automatic adjustment of the linings (7) depending on their wear is progressively brought about by predetermined spring forces which radially turn the adjusting ring (17) with wedge-shaped ramps (18) with respect to the bottom (2a) of the housing provided with ramps, thus causing an axial advance. The advance happens at the central swivelling point (12) of the cup spring (4).
Abstract:
A dry friction clutch assembly that includes a cover assembly. A friction disc is disposed in the cover assembly. A pressure plate is disposed in the cover assembly. The pressure plate is movably engaged and disengaged with the friction disc. A wear indicator assembly is disposed in a cavity of the cover assembly. The wear indicator assembly includes a connecting link coupled to the pressure plate. The wear indicator assembly includes an indicia portion connected to the connecting link, the indicia portion moveable in response to a position of the pressure plate. A variable amount of the indicia portion is viewed in a dust cover based upon movement of the indicia portion providing a visual indication of a wear state of the friction disc.

Abstract:
A friction clutch for a motor vehicle includes an adjustment mechanism compensating for wear of a friction disk. The adjustment mechanism (40) includes a first cam ring (52) rotatably fixed and a second cam ring (54) rotatable relative to the first cam ring (52). Both cam rings (52,54) have a plurality of cam surfaces configured such that rotation of the second cam ring (54) relative to the first cam ring (52) varies a height of the adjustment mechanism (40). A torsion spring (60) applies a biasing force to the second cam ring (54). A back drive prevention assembly (70) includes a back drive spring (80) attached to the pressure plate and first cam ring (52) to prevent back drive of the second cam ring (54) through a baffle (62) including a plurality of cam teeth (72) formed on a bottom surface of the baffle (62). The cam teeth (72) are formed at an angle A relative to a bottom surface of the baffle (62) decreasing displacement and loads of the back drive spring (80).
