ABSTRACT:
The device comprises four shift forks, each slidable among a first engagement position, a second engagement position and an intermediate neutral position between the two engagement positions, and an operating unit comprising four double-acting hydraulic actuators identical to each other and arranged to control each the displacement of a respective shift fork among the two engagement positions and the neutral position. The operating unit further comprises a support plate having holes for fixing to the gear case, and an actuator block accommodating the hydraulic actuators. The support plate and the actuator block are integrated to form a single body. In the assembled condition of the operating unit on the gear case, the actuator block is disposed on the side of the support plate facing towards the inside of the gear case.
