Title: Self-adjusting vehicle clutch cable
IPC: F16D23/12
Filed: 1984-03-13
Abstract: The engine clutch control has an abutment (5) located adjacent the cable near one end of the conduit (2) via which axial loads on the conduit can be transmitted to a fixture (4). - A conduit anchor (14) retains the conduit against axial displacement w.r.t. the abutment, and can be selectively released. The anchor has at least one tooth (17) which engages between projections (18) which are located, at successive positions along part of the conduit. A yieldable coupling (12,20) connects the conduit anchor and the core. (26pp Dwg.No. 1/9) EPAB- EP-118520 B An engine clutch control mechanism incorporating a flexible remote control cable comprising an inner member (1, 26, 50), (hereafter called "core"), longitudinally displaceable within a conduit (2, 27, 51), and incorporating an abutment (5, 29, 52), located adjacent the cable control near one end of the conduit (2, 27, 51), via which load on the conduit can be transmitted to a fixture (4, 53), and a conduit-anchoring device (13, 34, 42, 55) having at least one tooth (17, 39) which under a displacement force exerted on said device during an initial part of each clutch-oisengaging stroke of the core moves into intermeshing relationship with co-operating projections (18) thereby to anchor the said one end of the conduit against axial displacement relative to said abutment (there being a series of such projections extending along at least part of the conduit so as to afford a succession of adjustment positions), said device (14, 34, 42, 55) becoming automatically returned to conduit-release position as the pedal or other actuating member approaches the end of its return (clutch-engaging stroke, thereby to allow change in the effective length of the cable control to take place under any residual loading of the cable by the clutch-return spring; characterised in that there is means (12, 20, 24-25, 37-30, 44-46-48-30) forming a yielding coupling between said conduit-anchoring device (13, 34, 42, 55) and the core (1, 26, 50), which coupling services during an initial part of a clutch-releasing stroke of the core to transmit force from the core to the said conduit-anchoring device (13, 34, 42, 55) thereby to cause said displacement thereof, into conduit-anchoring position, whereafter said coupling yields to allow said clutch-disengaging stroke of the core (1, 26, 50) to continue while the conduit (2, 27, 51) remains anchored by said conduit-anchoring device. - EP-118520 B An engine clutch control mechanism incorporating a flexible remote control cable comprising an inner member (1, 26, 50), (hereafter called "core"), longitudinally displaceable within a conduit (2, 27, 51), and incorporating an abutment (5, 29, 52), located adjacent the cable control near one end of the conduit (2, 27, 51), via which load on the conduit can be transmitted to a fixture (4, 53), and a conduit-anchoring device (13, 34, 42, 55) having at least one tooth (17, 39) which under a displacement force exerted on said device during an initial part of each clutch-oisengaging stroke of the core moves into intermeshing relationship with co-operating projections (18) thereby to anchor the said one end of the conduit against axial displacement relative to said abutment (there being a series of such projections extending along at least part of the conduit so as to afford a succession of adjustment positions), said device (14, 34, 42, 55) becoming automatically returned to conduit-release position as the pedal or other actuating member approaches the end of its return (clutch-engaging stroke, thereby to allow change in the effective length of the cable control to take place under any residual loading of the cable by the clutch-return spring; characterised in that there is means (12, 20, 24-25, 37-30, 44-46-48-30) forming a yielding coupling between said conduit-anchoring device (13, 34, 42, 55) and the core (1, 26, 50), which coupling services during an initial part of a clutch-releasing stroke of the core to transmit force from the core to the said conduit-anchoring device (13, 34, 42, 55) thereby to cause said displacement thereof, into conduit-anchoring position, whereafter said coupling yields to allow said clutch-disengaging stroke of the core (1, 26, 50) to continue while the conduit (2, 27, 51) remains anchored by said conduit-anchoring device. (13pp) USAB- US4717004 A The engine clutch control incorporates a flexible remote control cable comprising a core which is axially displaceable within a conduit, is provided with a self-adjuster for compensating for clutch wear. The self-adjuster comprises a conduit-anchor for anchoring the conduti to an abutment held by a fixture. When the conduit-anchor is in its operative position it makes tooth engagement with the conduit. - The conduit-anchor is connected to the core via a yielding coupling so that the device is displaced into conduit-engaging position by forece transmitted to it form the core during an initial part of the operative stroke of the core. Following anchorage of the conduit to the abutment the operative stroke of the core continues to completion. On the return stroke the conduit anchor is released to allow conduit end to move relative to the abutment under any residual force exerted by the clutch return spring when the clutch pedal has reached the limit of its movement.
