Patent GB-2311828-A (GB)
Title: A friction clutch having an automatic wear adjuster activated by an increase in release load
Inventor: UEHARA HIROSHI
IPC: F16D13/75
Filed: 1997-02-14
Abstract: A friction clutch comprises a diaphragm spring 6 supported in a fulcrum support portion 1a by ring members 7. Wear on clutch friction facing members 4 results in an increase in displacement of pressure plate 5 and an increase in clutch release load which pulls the support portion 1a towards the facing members 4 and deflects connecting pieces 1b, thereby causing annular disc 1c to also deflect. The defection of connecting pieces 1b produces an axial gap, between the pieces 1b and base ends thereof, that is bridged by a circumferentially sliding wedged shaped slider ring 11 (also see fig 5) thus, retaining the annular disc 1c, the support portion 1a and the spring 6 at a compensated position. Connecting pieces 1b are formed so that, even when the orientation of the spring 6 changes as a result of the wear of the facing 4, the part the spring 6 that engages release bearing 8 remains substantially fixed. Tension springs (12, fig 1) urge the slider ring 11 in the circumferential direction to side wedge vanes (11a, fig 1) over and under the base ends of pieces 1b so that they axially force the portion 1c downward against a resilient force produced by the pieces 1b.
