AUTOMATIC ADJUSTING DEVICE

摘要

An automatic adjusting device for a twin-plate clutch includes a pin (9) which is mounted in a bore formed in an intermediate pressure plate (7) of the clutch so as to be slidable along an axis parallel to the axis of rotation of the clutch. First (8) and second (10) abutments are provided adjacent to the pin, the first (10) abutment providing a stop for determining adjustment of the pin relative to the intermediate pressure plate and the second abutment providing a stop for determining an intermediate position of the intermediate pressure plate. A plate (11) is mounted on the pin by way of an aperture provided in the plate, the aperture being dimensioned such that the plate is tiltable relative to the pin. A third abutment (13) is provided on the intermediate pressure plate and is engageable with the tiltable plate, the third abutment defining an axis about which the plate is tiltable. A resilient member in the form of a coil spring (17) urges the tiltable plate in the axial direction of the clutch and towards the third abutment so as to cause the plate to tilt and to engage the pin. This permits adjustment of the pin relative to the intermediate pressure plate when the pin is urged against the first abutment and inhibits movement of the pin relative to the intermediate pressure plate when the pin is urged against the second abutment.
