ABSTRACT:
A control device for a gearbox of a vehicle is provided with fixed support. A control element carried by the fixed support is able to move along a first axis to carry out a gear rank selection operation and also able to rotate about the first axis to carry out a gear engagement/disengagement operation. An actuator having an output element movable along a second axis is orthogonal to the first axis and cooperating with the control element to rotate it about the first axis. An engagement element carried in an integral manner by the control element is also provided. A cam which can be activated selectively and is suitable for cooperating in a sliding manner with the engagement element to displace the control element axially by a predetermined quantity during the rotation of the control element about the first axis is included. Selective activation of the cam during the gear selection operation is possible.
