Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 304 words
A clutch actuator assembly for a motor vehicle clutch of the type being normally resiliently loaded to an engaged position effecting power transfer between the engine and transmission of the vehicle, the clutch actuator assembly comprising: A. a pedal member having a generally U-shaped cross-section pivotally mounted in the vehicle and defining an elongated longitudinal axis; B. a cable assembly including a cable fixed at one end to the vehicle clutch; C. a rack-like adjuster member axially slidably received within said pedal member U-shaped cross-section for slidable movement along said pedal member longitudinal axis and including means for attachment to the other end of said cable; D. axially resilient means in the form of a coil tension spring received within said pedal member U-shaped cross section and aligned on said longitudinal axis with said spring's one end fixed to said adjusting member and said spring's other end grounded to said pedal member; E. an actuator member pivotally mounted in the vehicle within the pedal member about the same axis as said pedal member, and including guide means for receiving the cable; F. means defining a toothed surface on said actuator member and a complementary toothed surface on said adjusting member in juxtaposition therewith, the complementary toothed surfaces being fully engaged to axially fix said cable with respect to said pedal and actuator member upon certain pivotal movement of said pedal member toward a position effecting disengagement of said clutch and said toothed surfaces being less than fully engaged upon certain pivotal movement of said pedal member toward a position effecting engagement of the clutch; and G. stop means on the vehicle engageable with the actuator member for limiting separating movement between the complementary toothed surfaces, whereby axial movement of said cable with respect to said pedal and actuator members permits compensation for clutch wear.
