Abstract

1490566 Clutch control FRAYMON SAE 29 Nov 1974 [6 Dec 1973] 51713/74 Heading F2L In a clutch control for a motor vehicle wherein a pedal 1 acts through a master cylinder 14, fluid column 10, slave cylinder 4 and linkage 12, 13 on a thrust release bearing 7, the complete pedal travel only moves the thrust bearing 7 sufficiently to just disengage the clutch and thereafter complete separation of the plates of the clutch is effected by a vacuum or compressed air servo-motor 8 controlled by a valve 18 responsive to the pressure in the fluid column 10. As shown, when the pedal 1 has completed its stroke the pressure in the column 10 is sufficient to open the valve 18 which supplies pressure air from a vehicle brake actuating reservoir 15 to the servo-motor 8. Initial movement of a piston 5 of the servo-motor 8 closes an inlet 17 to the slave cylinder 4 and thereafter acts through the fluid in the slave cylinder, the slave piston 6 and linkage 12, 13 on the thrust bearing 7 to separate the clutch plates. The valve 18 is adjustably spring loaded to permit the pressure at which the valve 18 operates to be adjusted to that prevailing when the pedal 1 has completed its stroke. In Fig. 2 (not shown) the slave cylinder 4 is separate from the servo-motor piston 5.
