<p>The device substantially comprises a manually operated lever (L) for a gearbox that oscillates on one plane and can be set in a first (1) position and in a second (2) angular position in each of which the driving means of the device are activated, respectively, in a first and in a second configuration in which they control the manoeuvres for selecting and engaging, respectively, a higher or lower gear, and that may also be set into a third (3) and a fourth (4) angular position corresponding to a greater angle than that reached in the previous positions and in each of which said driving means are activated respectively in a third and in a fourth configuration in which they control the manoeuvres for selecting and engaging a higher or lower gear, said manoeuvres being performed with a greater activating force than that with which the same manoeuvres are performed with the lever in the first or second position; the device also comprises means of resistance (R) adapted to generate a resistant torque of a preset value for moving the gear lever from the first (1) to the third (3) angular position and from the second (2) to the fourth (4) angular position.</p> |
