A system for reducing the force to actuate the clutch pedal in automobiles is described, wherein the clutch-actuating pedal (2) is fixed to one end of an actuating arm (1), which has, at its other end, a pivot pin (3) as an integral part of the free end of the rod (4), the actuating arm (1) being further pivoted around a pivot pin (6) located between its ends and fixed to the vehicle body (not shown), so that a force applied on to the pedal (2) causes the pivot pin (3), provided at the other end of the actuating arm (1), to actuate, pressing the rod (4) of the plunger of the clutch master cylinder (5). This invention reduces the actuating force with a system in which the actuating arm (1), upon actuating the pedal (2), pivot pin (3) and, consequently, the lever arm (X), where the force on the rod is applied, describe a rotational path (A) around the pin (6). The component of the lever arm (X), which influences the moment applied to the pin (6), decreases as the lever arm follows the path (A), thus reducing the moment and the effort required from the driver to actuate the clutch. In addition, the master cylinder (5) itself is pivotable around a pin (9), fixed to the support (10) on the vehicle body, allowing the rod (4) to accommodate the pivot pin (3), when the latter follows the path (A), so as to enable the rod (4) to penetrate further into the master cylinder (5) of the clutch. |
