An electromechanical servocontrol device to engage and disengage the clutch in motor vehicle speed gears, said device comprising an electric position transducer (2) connected to the accelerator pedal (1), a device (3) for generating a parabolic type function signal that correlates the motions of the accelerator pedal (1) and of the clutch drive means (12), means (14,16,17) for detecting the motor vehicle speed directly on a wheel (13), a switching device (5) that blocks the signal coming from the accelerator (1) when the speed reaches a value above a given threshold, receiving the signal from an electric contact (7) or similar devices arranged on the speed gear lever, a device for calibrating said threshold speed, a servomotor (10) connected to the clutch drive means (12), a second electric position transducer (11) of the clutch (12), a device (8) for comparing the desired position of the clutch (12) with the position pointed out by said second electric transducer (11), said comparison device (8) being connected on one side to the switching device (6) and, on the other side, to the servomotor (10) through a power amplifier (9), and a contact device (18) on the braking system of the motor vehicle which is connected to said power amplifier (9) and to a pulse generator (15) connected to the system that detects the motor vehicle speed. |
