Abstract
The control system including four actuating forks, each associated to one or two gears and having a first engagement member, and a first hydraulically-operated actuator for controlling engagement of all gears. The first hydraulically-operated actuator includes: a shaft provided with four second engagement members for engagement each with a respective first engagement member of the actuating forks and arranged to turn about and translate along its axis; a cylinder coaxial to the shaft and arranged only to translate in the direction of its axis; and a pin drivingly connected either to the shaft or the cylinder and engaging in an S-shape groove provided either in the cylinder or shaft, respectively, so as to link the rotational and translational movements of the shaft with the translational movement of the cylinder. A second hydraulically-operated actuator is arranged to lock or release selectively the translational movement of the cylinder.
