| 摘要 | A self-adjusting clutch release mechanism comprising a clutch pedal normally held against a stop by a return spring. A pawl is pivotally connected to the pedal and engages a ratchet member that is linked to the release lever of a clutch. Displacement of the ratchet member by the pawl when the pedal is moved disengages the clutch. The pawl disengages from the ratchet member when the pedal is held against the stop. A spring connected to the ratchet member takes up any slack in the connection between the ratchet member and the clutch when the pawl is disengaged. | ||||||
| 权利要求 | 1. A self-adjusting actuating mechanism comprising a pivotally mounted lever, stop means constructed to engage said lever when it is in a first position, spring means constructed to urge said lever to said first position, ratchet means constructed to be connected to an actuatable mechanical device, pawl means pivotally connected to said lever, said ratchet means being movably supported relative to said pawl, means urging said pawl means into engagement with said ratchet means, stop means engaging said pawl when said lever is in said first position causing said pawl to be disengaged from said ratchet, said pawl means engaging said ratchet means when said lever is in a second position and constructed to transmit motion from said lever to said ratchet means. 2. A self-adjusting actuating mechanism comprising a pivotally mounted lever, stop means constructed to engage said lever when it is in a first position, ratchet means constructed to be connected to an actuatable mechanical device, spring means conStructed to urge said ratchet means to an actuated position, pawl means pivotally connected to said lever, said ratchet means being movably supported relative to said pawl, means urging said pawl means into engagement with said ratchet means, stop means engaging said pawl when said lever is in said first position causing said pawl to be disengaged from said ratchet, said pawl means engaging said ratchet means when said lever is in a second position and constructed to transmit motion from said lever to said ratchet means. 3. A self-adjusting actuating mechanism comprising a pivotally mounted lever, stop means constructed to engage said lever when it is in a first position, first spring means constructed to urge said lever to said first position, ratchet means constructed to be connected to an actuatable mechanical device, second spring means constructed to urge said ratchet means to an actuated position, pawl means pivotally connected to said lever, said ratchet means being movably supported relative to said pawl, means urging said pawl means into engagement with said ratchet means, stop means engaging said pawl when said lever is in said first position causing said pawl to be disengaged from said ratchet, said pawl means engaging said ratchet means when said lever is in a second position and constructed to transmit motion from said lever to said ratchet means. 4. A self-adjusting actuating mechanism according to claim 1 and including: said ratchet means comprising a member supported to pivot about an axis coincident with the pivot axis of said lever, said member having ratchet teeth engageable by said pawl. 5. A self-adjusting clutch release mechanism comprising a pivotally mounted pedal, spring means constructed to urge said pedal to a first position, stop means constructed to engage said pedal when it is in said first position, ratchet means constructed to be connected to the clutch release lever of a clutch assembly, spring means urging said ratchet means to a clutch release position, pawl means pivotally connected to said pedal, spring means urging said pawl means into engagement with said ratchet means, stop means engaging said pawl means when said pedal is in said first position causing pawl means to be disengaged from said ratchet means, said pawl means engaging said ratchet means when said pedal is in a second position and constructed to transmit motion from said pedal to said ratchet means 6. A self-adjusting clutch release mechanism according to claim 5 and including: said ratchet means comprising a member supported to pivot about an axis coincident with the pivot axis of said pedal, said member having ratchet teeth engageable by said pawl. 7. A self-adjusting clutch release mechanism according to claim 6 and including: said member being pivotally supported on said pedal. 8. A self-adjusting actuating mechanism according to claim 2 and including: said ratchet means comprising a member supported to pivot about an axis coincident with the pivot axis of said lever, said member having ratchet teeth engageable by said pawl. 9. A self-adjusting actuating mechanism according to claim 3 and including: said ratchet means comprising a member supported to pivot about an axis coincident with the pivot axis of said lever, said member having ratchet teeth engagable by said pawl. |
